    Objective: To present our experience of treatment of complex anterior urethral strictures using penile skin flap. Study Design: Descriptive, case series. Place and Duration of Study: Department of urology Combined Military Hospital Malir Cantonment, Karachi and Armed Forces Institute of Urology, Rawalpindi from Jan 2012 to Feb 2014. Material and Methods: Total 18 patients with complex anterior urethral strictures and combined anterior and bulborurethral strictures were included. Patients underwent repair using Orandi or circularfacio-cutaneous penile skin flap depending upon the size and site of stricture. First dressing was changed after two days and an in dwelling silicone two way foleycatheter was kept in place for three weeks. Graft was assessed with regards to local infection, fistula formation and restricturing. Re-stricture was assessed by performing uroflowmetery at 6 months and 1 year. Ascending urethrogram was reserved for cases with less than 10 ml/sec Q max on uroflowmetery. Repair failure was considered when there was a need for any subsequent urethral procedure asurethral dilatation, dorsal visual internal urethrotomy, or urethroplasty. Results: Overall success rate was 83.3 percent. Of all the patients operated 1(5.6 percent) had infection with loss of flap, 3(16.7 percent) had urethral fistula and none had re stricture confirmed by uroflowmetery. Conclusion: In our study the excellent results of the penile skin flap both in anterior urethral strictures and combined anterior and bulbar urethral strictures are quite encouraging. It is easy to harvest and seems anatomically more logical. (author)

    To investigate effectiveness of advanced skin flap and V-shaped ventral incision along the root of penile shaft for concealed penis in children. Between July 2007 and January 2015, 121 boys with concealed penis were treated with advanced skin flap and V-shaped ventral incision along the root of penile shaft. The age varied from 18 months to 13 years (mean, 7.2 years). Repair was based on a vertical incision in median raphe, complete degloving of penis and tacking its base to the dermis of the skin. Advanced skin flap and a V-shaped ventral incision along the root of penile shaft were used to cover the penile shaft. The operation time ranged from 60 to 100 minutes (mean, 75 minutes). Disruption of wound occurred in 1 case, and was cured after dressing change; and primary healing of incision was obtained in the others. The follow-up period ranged from 3 months to 7 years (median, 24 months). All patients achieved good to excellent cosmetic results with a low incidence of complications. The results were satisfactory in exposure of penis and prepuce appearance. No obvious scar was observed. The penis had similar appearance to that after prepuce circumcision. A combination of advanced skin flap and V-shaped ventral incision along the root of penile shaft is a simple, safe, and effective procedure for concealed penis with a similar appearance result to the prepuce circumcision.

    To present an improved tubularized flap (ITF) technique and report the outcome of single-stage urethroplasty using preputial/penile skin flaps (PSFs) for the treatment of obliterative anterior urethral strictures (AUSs). From January 2000 to June 2012, 42 cases of obliterative AUS (3-14 cm, mean 6.38 cm) with urethral plate unsalvageable were treated using PSF-ITF urethroplasty including longitudinal skin flap, circular island flap, L-flap, Q-flap. Patients were divided into 3 groups: pendulous urethral stricture (Group A), bulbar urethral stricture (Group B) and panurethral strictures (Group C). Patients were followed up by uroflowmetry, urethrography and ureteroscope when necessary. The mean follow-up in these patients was 65 months (range 36 months-15 years). The primary success rates at 3-year follow-up were 75, 75 and 60% for Groups A, B and C, respectively. The overall success rates were 85, 83 and 70% with the remedial measure of a single visual internal urethrotomy at 3-year follow-up. A total 60% of the patients in the study completed more than 5 years of follow-up with no additional recurrence. Improved tubularized preputial/PSF urethroplasty with relatively high overall satisfaction is a novel technique for treatment of AUS when there is inadequate urethral plate or obliterative defects. © 2016 S.

    Full Text Available ABSTRACT Purpose To evaluate the surgical outcome and predictors of failure of substitution urethroplasty using either dorsal onlay buccal mucosal (BM graft or ventral onlay penile skin flap (PS for anterior urethral stricture ≥ 8cm. Patients and methods Between March 2010 and January 2016, 50 patients with anterior urethral stricture ≥ 8 cm were treated at our hospital. The surgical outcome and success rate were assessed. The predictors of failure were analyzed using multivariate analysis. Failure was considered when subsequent urethrotomy or urethroplasty were needed. Results Dorsal onlay BM graft was carried out in 24 patients, while PS urethroplasty in 26 patients. There was no significant difference between both groups regarding patients demographics, stricture characteristics or follow-up period. One case in the BM group was lost during follow-up. Stricture recurrence was detected in 7 (30.4% patients out of BM group while in 6 (23.1% patients out of PS group (p value= 0.5. No significant differences between both groups regarding overall early and late complications were observed. Occurrence of early complications and the stricture length were the only predictors of failure in univariate analysis, while in multivariate analysis the occurrence of early complications was only significant. Conclusion On short-term follow-up, both dorsal onlay BM graft and ventral onlay PS flap urethroplasty have similar success rates. However, BM graft has a potential advantage to reduce operative time and is also technically easier. The surgeon should avoid early local complications as they represent a higher risk for failure.

  6. The transverse penile pedicled flap urethroplasty: description of a simplified technique for the dissection of the Fascio-cutaneous flap.

    Urethroplasty is often required for long urethral strictures or urethral strictures that have recurred after repeated urethral dilatations or urethrotomy. The transvers penile skin pedicled flap is very versatile for the reconstruction of long urethral stricture. However the meticulous sharp dissection required to develop it takes a long time to do and may be associated with button hole injuries to the vascular pedicle and the penile skin. We describe a simplified technique of raising the flap which does not require sharp dissection and is very quick to accomplish. Technique involves using a circumcising distal penile shaft skin incision to de-glove the penis by blunt dissection. The skin substitute, adequate to give appropriate urethra calibre is similarly dissected bluntly along with its vascular pedicle from the proximal penile skin. The techniques used to facilitate successful blunt dissection are described. In 9 adults with long, multiple urethral strictures, the average time to develop the flap was 15 minutes and complication have been limited to temporary urethro-cutaneous fistula at the ventral part of the circular skin closure. These fistulae closed on conservative treatment. No patient suffered button-hole injuries to either the vascular pedicle or the penile skin. This modification to the standard sharp dissection is very quick to accomplish. It also avoids the creation of button-hole injuries to either the vascular pedicle or the penile skin. It should make the use of this versatile flap more attractive in the reconstruction of long urethral strictures in those who may wish to use this option for reconstruction of long urethral strictures.

    We investigated a reconstructive method with better sensory and erectile function for partial penile defects and report our long-term results of surgical correction using scrotal skin flaps. We retrospectively analyzed the records of 18 patients with penile defects referred to us between 1992 and 2007. All cases were treated with a scrotal skin flap initially to repair the secondary defect after penile elongation. Of the 18 cases treated during the 15-year period the mechanism of primary injury was circumcision in 3, animal bite in 9 and penile tumor dissection in 6. Penile elongation, division of the suspensory ligament and scrotal skin flaps achieved penile augmentation and enhancement. Six cases were treated with a bilateral scrotal skin flap supplied by the anterior scrotal artery and 12 were repaired with a total anterior scrotal skin flap supplied by the anterior and posterior scrotal arteries. Penile length in the flaccid and erectile states was obviously increased postoperatively (p <0.05). All patients were followed 1 to 9 years (mean 2.3) postoperatively. Deep and superficial sensation recovered and erectile function was retained. Of the 18 patients 15 reported satisfied sexual intercourse during the 0.5 to 5-year followup. The method of correcting partial penile defect using scrotal skin flaps is effective and simple according to our long-term experience. This method achieves reasonable cosmesis and penile length in most cases with better sensory and erectile function.

  8. Tubularized Penile-Flap Urethroplasty Using a Fasciocutaneous Random Pedicled Flap for Recurrent Anterior Urethral Stricture

    Full Text Available This report describes the use of a tubularized random flap for the curative treatment of recurrent anterior urethral stricture. Under the condition of pendulous lithotomy and suprapubic cystostomy, the urethral stricture was removed via a midline ventral penile incision followed by elevation of the flap and insertion of an 18-Fr catheter. Subcutaneous buried interrupted sutures were used to reapproximate the waterproof tubularized neourethra and to coapt with the neourethra and each stump of the urethra, first proximally and then distally. The defect of the penile shaft was covered by advancement of the surrounding scrotal flap. The indwelling catheter was maintained for 21 days. A 9 month postoperative cystoscopy showed no flap necrosis, no mechanical stricture, and no hair growth on the lumen of the neourethra. The patient showed no voiding discomfort 6 months after the operation. The advantages of this procedure are the lack of need for microsurgery, shortening of admission, the use of only spinal anesthesia (no general anesthesia, and a relatively short operative time. The tubularized unilateral penile fasciocutaneous flap should be considered an option for initial flap urethroplasty as a curative technique.

    Although a tourniquet is frequently used in penile surgery there is still no consensus on safe application time. The aim of the present study is to investigate the effect of malondialdehyde (MDA) levels and histological changes in skin flaps after penile tourniquet application and epinephrine injection. A total of 36 male white New Zealand rabbits were randomly divided into six groups each containing six animals. A Mathieu-like flap was raised in all of the groups and a tourniquet was applied and the penis was subjected to ischemia for 10, 20 and 40 min in groups 1, 2 and 3, respectively. The flaps were then allowed to reperfuse for 5 min. Biopsies for MDA measurement were harvested in these groups. Subcutaneous 1/200,000 epinephrine was injected into penile skin in group 4 and 5 rabbits and biopsies for MDA measurement were harvested 10 and 40 min after injection. The control group was anesthetized without tourniquet usage or epinephrine injection. Specimens taken from the harvested flaps of all groups were submitted for histological evaluation. The mean MDA levels in all experimental groups were higher than in the control group and the difference was statistically significant. Edema, congestion and extravasation were observed in groups 1, 2 and 3. Minimal congestion and edema were observed in group 4 and severe edema and extravasation in group 5. Tourniquet usage for a duration of less than 10 min is clearly safer than prolonged usage. Epinephrine injection to penile skin may show a deleterious effect on wound healing.

  11. One-sheet spiraling full thickness skin graft for penile resurfacing after paraffinoma excision

    2011-08-01

    Full Text Available In the midst of on-going non-illicit practice of silicone or paraffin injection to enlarge penis, the author reported 3 cases of surgical treatment to resurface the body of the penis after excision of the destructed penile skin using full thickness skin graft. The skin excision was performed technically through penile body degloving procedure. Full thickness skin graft was then applied as a single sheet donor tissue to cover the denuded penile body spirally. The full thickness graft, which is relatively easy to be performed, is no doubt much thinner than a skin flap, while it also bears a smaller degree of secondary contraction than split skin graft. The color of the skin is considerably matched as it comes from the groin, which is a nearby area of penis. The size and skin sensitization of the penis looks to be natural. The only disadvantage is the common possibility of either spiral or circular junctional scar in between graft edges and between the graft and the penile mucosa and skin to develop hypertrophic scar. However, this possible scar problem applies also to any other surgical scar with any donor tissue. Fortunately, the 3 cases posed no scar problem and normal appearance. All the patients have also regained their normal sexual function. (Med J Indones 2011; 20:222-5Keywords: full thickness skin graft, paraffinoma, siliconoma, sexual function

  12. Penile lengthening procedure with V-Y advancement flap and an interposing silicone sheath: A novel methodology

    2012-01-01

    Full Text Available Surgery to augment penile length has become increasingly common. Lack of standardization of this controversial procedure has led to a wide variety of poorly documented surgical techniques, with unconvincing results. The most commonly used technique involves release of the suspensory ligament, with an advancement of an infrapubic skin flap onto the penis via a V-Y plasty. This technique has a major drawback of the possibility of reattachment of the penis to the pubis. We describe a new technique of interposing a silicone sheath along with V-Y advancement flap that overrides this drawback and minimizes the loss of the gained length.

    The reaction of skin flaps to irradiation and the optimum postoperative time for irradiation was studied in the rat. Flaps showed different reactions depending on the time of irradiation. There was a correlation between the radiosensitivity and the vascularity of the flap. Those flaps in the marginal hypovascular stage of revascularization showed reactions similar to normal skin. However, severe adverse reactions were observed in the marginal hypervascular stage

    Full Text Available Objectives. Severe penile inadequacy in adolescents is rare. Phallic reconstruction to treat this devastating condition is a major challenge to the reconstructive surgeon. Phallic reconstruction using the free radial forearm flap (RFF or the pedicled anterolateral thigh flap (ALTF has been routinely used in female-to-male transsexuals. Recently we started to use these techniques in the treatment of severe penile inadequacy. Methods. Eleven males (age 15 to 42 years were treated with a phallic reconstruction. The RFF is our method of choice; the ALTF is an alternative when a free flap is contraindicated or less desired by the patient. The RFF was used in 7 patients, the ALTF in 4 patients. Mean followup was 25 months (range: 4–49 months. Aesthetic and functional results were evaluated. Results. There were no complications related to the flap. Aesthetic results were judged as “good” in 9 patients and “moderate” in 2 patients. Sensitivity in the RFF was superior compared to the ALTF. Four patients developed urinary complications (stricture and/or fistula. Six patients underwent erectile implant surgery. In 2 patients the erectile implant had to be removed due to infection or erosion. Conclusion. In case of severe penile inadequacy due to whatever condition, a phalloplasty is the preferred treatment nowadays. The free radial forearm flap is still the method of choice. The anterolateral thigh flap can be a good alternative, especially when free flaps are contraindicated, but sensitivity is markedly inferior in these flaps.

    Full Text Available Introduction: Viscoelastic properties of skin in coloured ethnic groups are less favourable compared to Caucasians for executing Keystone flaps. Keystone flaps have so far been evaluated and reported only in Caucasians. The potential of Keystone flaps in a coloured ethnic group is yet unknown. Aim: This article reviews the experience to reconstruct skin defects presenting in a coloured ethnic group, by using Keystone flaps, with a review of existing literature. Design: Uncontrolled case series. Materials and Methods: This retrospective review involves 55 consecutive Keystone flaps used from 2009 to 2012, for skin defects in various locations. Patient demographic data, medical history, co-morbidity, surgical indication, defect features, complications, and clinical outcomes are evaluated and presented. Results: In this population group with Fitzpatrick type 4 and 5 skin, the average patient age was 35.73. Though 60% of flaps (33/55 in the series involved specific risk factors, only two flaps failed. Though seven flaps had complications, sound healing was achieved by suitable intervention giving a success rate of 96.36%. Skin grafts were needed in only four cases. Conclusions: Keystone flaps achieve primary wound healing for a wide spectrum of defects with an acceptable success rate in a coloured skin population with unfavorable biophysical properties. By avoiding conventional local flaps and at times even microsurgical flaps, good aesthetic outcome is achieved without additional skin grafts or extensive operative time. All advantages seen in previous studies were verified. These benefits can be most appreciated in coloured populations, with limited resources and higher proportion of younger patients and unfavorable defects.

    Full Text Available Avulsions of penile and scrotal skin are uncommon events and are caused mainly by accidents with industrial machines and agricultural machine belts. We report the case of a 30-year old patient with avulsion and traumatic degloving of the penile and scrotal skin, with exposure of the cavernous bodies, spongy body, and testes due to an industrial machine accident. Reconstruction was performed in steps, achieving a satisfactory esthetic result, normal voiding and reestablished sexual function.

    Full Text Available The main objective in dermatologic surgery is complete excision of the tumour while achieving the best possible functional and cosmetic outcome. Also we must take into account age, sex, and tumour size and site. We should also consider the patient's expectations, the preservation of the different cosmetic units, and the final cosmetic outcome. Various reconstructive methods ranging from secondary healing to free flap applications are usedfor the reconstruction of perinasal or facial defects caused by trauma or tumour surgery. Herein, we describe the nasal infraorbital island skin flap for the reconstruction in a patient with basal cell carcinoma. No complications were observed in operation field. The infraorbital island skin flap which we describe for the perinasal area reconstruction is a safe, easily performed and versatile flap. The multidimensional use of this flap together with a relatively easy reconstruction plan and surgical procedure would be effective in flap choice.

    2016-01-01

    Discussion and conclusion: Various techniques are available for penile skin covering, such as skin grafts or cutaneous flaps. The skin of the scrotum seems to be the most suitable tissue to be used to reconstruct the skin covering of the shaft as it is the most similar. Dartos-fascio-myo-cutaneous flap is a single stage procedure that is easy and safe to perform. It can provide satisfactory cosmetic and functional results, offering a large amount of tissue, with minimal donor site morbidity.

    Full Text Available Objective. The influence of Coherent Ultrapulse, TruPulse and Erbium: YAG laser skin resurfacing on survival of the skin flaps when performed simultaneously was evaluated. Material and methods. We used twelve female Yucatan minipigs in the study. Skin flaps including paniculus carnosus were raised on the animals’ back. The flaps were sutured into the defect under tension. We designed 4 experimental groups: Control-Flaps only, Group 2-Flaps + 4 immediate TruPulse laser passes, Group 3-Flaps + 2 immediate Coherent UltraPulse laser passes, Group 4-Flaps – immediate 50J/cm2 total fluence with Erbium: YAG laser. Results. Flap survival in Control group was 98.8%. There was no flap in Group 2 with complete survival. Survival of the flaps in Group 2 (Tru-Pulse ranged from 75-90%, with average flap survival area of 85.2%. In Group 3 (UltraPulse all 24 flaps had some area of necrosis. Flap survival in Group 3 ranged from 75-95%, with an average of 85.6%. In Group 4 (Erbium: YAG flap survival area ranged from 70-95%, with all 24 flaps with some area of necrosis, with average flap survival area of 87.3%. There is a significant statistical difference in flap survival area between groups 2, 3 and 4 versus Control (p<0.001. Conclusion. The results of our study suggest that laser resurfacing of skin flaps sutured under tension in the same operative session is detrimental for skin flap survival. We also found no significant difference in flap survival area between TruPulse, Coherent UltraPulse and Erbium: YAG laser treated flaps.

    Penile cancer is a rare malignancy that is confined to the glans in up to four out of five cases. Although descriptions of glansectomy exist, there are no contemporary video explanations or large published single centre series. To show the efficacy and safety of glansectomy and split-thickness skin graft (STSG) reconstruction. Data were collected retrospectively for patients identified from surgical theatre diaries between February 2005 and January 2016. 177 patients with histologically proven squamous-cell carcinoma on the glans underwent glansectomy and STSG at a tertiary referral centre in the UK. The median follow-up was 41.4 mo. The skin is incised at the subcoronal level and deepened onto Buck's fascia. Dissection is performed over or under Buck's fascia, depending on suspicion of invasion or risk of disease. The glans is excised and a neoglans is created using a STSG. Local recurrence, cancer-specific survival, overall survival, and complications. Sixteen out of 172 patients (9.3%) experienced local recurrence during the follow-up period. Eighteen out of 174 (10.7%) patients died of penile cancer, while 29 patients in total died during the follow-up period. Of 145 patients, 9% required operative intervention for complications, including graft loss and meatal stenosis. Limitations include the retrospective data collection and the lack of functional and sexual outcomes. Glansectomy and STSG comprise a safe procedure in terms of oncologic control and complications for patients with penile cancer confined to the glans penis. Further studies are required to assess functional and sexual outcomes in these patients. We report on the management of penile cancers confined to the head of the penis using glansectomy and a split-thickness skin graft to recreate the appearance of a glans. This technique is safe and effective, with limited complications. Copyright © 2016. Published by Elsevier B.V.

    To provide sexual function and quality of life outcomes in patients with severe penile deficiency who underwent radial forearm flap phalloplasty with and without penile prosthesis implantation. Patients with history of severe penile deficiency who underwent microsurgical radial forearm flap phalloplasty with and without penile prosthesis implantation between 2007 and 2014 were identified. They completed a set of web-based validated questionnaires including the International Index of Erectile Function, the Pediatric Penile Perception Score, the Sexual Quality of Life for Men, and several items addressing general quality of life. Outcomes were compared between groups. Nine of the 12 identified patients who had prosthesis after phalloplasty and 4 out of the 7 phalloplasty-only patients completed the survey, resulting in an overall response rate of 68%. Among the phalloplasty-prosthesis patients, 66% reported current sexual activity and 78% reported regular masturbation, whereas 1 of the 4 phalloplasty-only patients reported both. Prosthesis patients scored notably higher in all domains of the International Index of Erectile Function except for sexual desire. In contrast, they demonstrated similar scores of penile perception, as well as general and sexual quality of life. Among patients who have undergone flap phalloplasty, the subsequent placement of penile prosthesis appears to effectively allow for both intercourse and masturbation, resulting in measurable improvements in orgasmic function, intercourse satisfaction, and overall sexual satisfaction. Despite these important benefits, prosthesis placement does not appear to result in improvements in penile perception scores, or general or sexual quality of life. Copyright © 2017 Elsevier Inc.

    The microflora of the penile skin-lined neovagina in male-to-female transsexuals is a recently created microbial niche which thus far has been characterized only to a very limited extent. Yet the knowledge of this microflora can be considered as essential to the follow-up of transsexual women. The primary objective of this study was to map the neo-vaginal microflora in a group of 50 transsexual women for whom a neovagina was constructed by means of the inverted penile skin flap technique. Secondary objectives were to describe possible correlations of this microflora with multiple patients' characteristics, such as sexual orientation, the incidence of vaginal irritation and malodorous vaginal discharge. Based on Gram stain the majority of smears revealed a mixed microflora that had some similarity with bacterial vaginosis (BV) microflora and that contained various amounts of cocci, polymorphous Gram-negative and Gram-positive rods, often with fusiform and comma-shaped rods, and sometimes even with spirochetes. Candida cells were not seen in any of the smears. On average 8.6 species were cultured per woman. The species most often found were: Staphylococcus epidermidis, Streptococcus anginosus group spp., Enterococcus faecalis, Corynebacterium sp., Mobiluncus curtisii and Bacteroides ureolyticus. Lactobacilli were found in only one of 30 women. There was no correlation between dilatation habits, having coitus, rinsing habits and malodorous vaginal discharge on the one hand and the presence of a particular species on the other. There was however a highly significant correlation between the presence of E. faecalis on the one hand and sexual orientation and coitus on the other (p = 0.003 and p = 0.027 respectively). Respectively 82%, 58% and 30% of the samples showed an amplicon after amplification with M. curtisii, Atopobium vaginae and Gardnerella vaginalis primer sets.

    Full Text Available Abstract Background The microflora of the penile skin-lined neovagina in male-to-female transsexuals is a recently created microbial niche which thus far has been characterized only to a very limited extent. Yet the knowledge of this microflora can be considered as essential to the follow-up of transsexual women. The primary objective of this study was to map the neo-vaginal microflora in a group of 50 transsexual women for whom a neovagina was constructed by means of the inverted penile skin flap technique. Secondary objectives were to describe possible correlations of this microflora with multiple patients' characteristics, such as sexual orientation, the incidence of vaginal irritation and malodorous vaginal discharge. Results Based on Gram stain the majority of smears revealed a mixed microflora that had some similarity with bacterial vaginosis (BV microflora and that contained various amounts of cocci, polymorphous Gram-negative and Gram-positive rods, often with fusiform and comma-shaped rods, and sometimes even with spirochetes. Candida cells were not seen in any of the smears. On average 8.6 species were cultured per woman. The species most often found were: Staphylococcus epidermidis, Streptococcus anginosus group spp., Enterococcus faecalis, Corynebacterium sp., Mobiluncus curtisii and Bacteroides ureolyticus. Lactobacilli were found in only one of 30 women There was no correlation between dilatation habits, having coitus, rinsing habits and malodorous vaginal discharge on the one hand and the presence of a particular species on the other.

    Objectives: To evaluate the surgical outcome of tubularised incised plate urethroplasty and onlay island flap repair for mid and proximal penile hypospadias. Methods: The prospective study was conducted at the Bahawal Victoria Hospital, Bahawalpur from June 2011 to May 2013. A total of 60 patients with mid and proximal penile hypospadias in the age range of 02 to 06 years were included. Patients with hypospadias other than mid and proximal penile, with chordee and history of previous hypospadias repair were excluded. Patients were divided into two equal groups. Urethroplasty was done for group I and flap repair for group II. The follow-up period was 12-24 months. SPSS 16 was used for statistical analysis. Results: The mean duration of surgery was 62+-8.72 minutes for group I and 90+-11.25 minutes for group II (p<0.0001). In group I, only 03 (10.0%) patients had complications, while in group II, 09 (30.0%) patients developed complications (p=0.02). Cosmetic results were also excellent in group I compared to group II. Conclusion: Tubularised incised plate urethroplasty was better and superior than onlay island flap repair in terms of less operative time, complication rate and satisfactory cosmetic results for mid and proximal penile hypospadias.

    Full Text Available Flaps from temporal region have been used for mid face, orbital and peri-orbital reconstruction. The knowledge of the vascular anatomy of the region helps to dissect and harvest the muscle/fascia/skin/combined tissue flaps from that region depending upon the requirement. Suprastructure maxillectomy defects are usually covered with free flaps to fill the cavity. Here we report an innovative idea in which a patient with a supra structure maxillectomy with external skin defect was covered with chimeric flap based on the parietal and frontal branches of superficial temporal artery and the temporalis muscle flap based on deep temporal artery.

    Resurfacing of facial massive soft tissue defect is a formidable challenge because of the unique character of the region and the limitation of well-matched donor site. In this report, we introduce a technique for using the prefabricated cervicothoracic skin flap for facial resurfacing, in an attempt to meet the principle of flap selection in face reconstructive surgery for matching the color and texture, large dimension, and thinner thickness (MLT) of the recipient. Eleven patients with massive facial scars underwent resurfacing procedures with prefabricated cervicothoracic flaps. The vasculature of the lateral thigh fascial flap, including the descending branch of the lateral femoral circumflex vessels and the surrounding muscle fascia, was used as the vascular carrier, and the pedicles of the fascial flap were anastomosed to either the superior thyroid or facial vessels in flap prefabrication. A tissue expander was placed beneath the fascial flap to enlarge the size and reduce the thickness of the flap. The average size of the harvested fascia flap was 6.5 x 11.7 cm. After a mean interval of 21.5 weeks, the expanders were filled to a mean volume of 1,685 ml. The sizes of the prefabricated skin flaps ranged from 12 x 15 cm to 15 x 32 cm. The prefabricated skin flaps were then transferred to the recipient site as pedicled flaps for facial resurfacing. All facial soft tissue defects were successfully covered by the flaps. The donor sites were primarily closed and healed without complications. Although varied degrees of venous congestion were developed after flap transfers, the marginal necrosis only occurred in two cases. The results in follow-up showed most resurfaced faces restored natural contour and regained emotional expression. MLT is the principle for flap selection in resurfacing of the massive facial soft tissue defect. Our experience in this series of patients demonstrated that the prefabricated cervicothoracic skin flap could be a reliable alternative

    Development of effective (trans)dermal drug delivery systems requires reliable skin models to evaluate skin drug penetration. The isolated perfused human skin flap remains metabolically active tissue for up to 6h during in vitro perfusion. We introduce the isolated perfused human skin flap as a close-to-in vivo skin penetration model. To validate the model's ability to evaluate skin drug penetration the solutions of a hydrophilic (calcein) and a lipophilic (rhodamine) fluorescence marker were applied. The skin flaps were perfused with modified Krebs-Henseleit buffer (pH7.4). Infrared technology was used to monitor perfusion and to select a well-perfused skin area for administration of the markers. Flap perfusion and physiological parameters were maintained constant during the 6h experiments and the amount of markers in the perfusate was determined. Calcein was detected in the perfusate, whereas rhodamine was not detectable. Confocal images of skin cross-sections shoved that calcein was uniformly distributed through the skin, whereas rhodamine accumulated in the stratum corneum. For comparison, the penetration of both markers was evaluated on ex vivo human skin, pig skin and cellophane membrane. The proposed perfused flap model enabled us to distinguish between the penetrations of the two markers and could be a promising close-to-in vivo tool in skin penetration studies and optimization of formulations destined for skin administration.

    Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016. Multiple incisions were made along the facial esthetic line on the keloid mass. The keloid skin was dissected and elevated as a skin flap with one or two pedicles. The scar tissue in the keloid was then removed through the incision. The wound was covered with the preserved keloid skin flap and closed without tension. Radiotherapy and hyperbaric oxygen were applied after surgery. Patients underwent follow-up examinations 6 and 12 months after surgery. Of the 45 total patients, 32 patients were cured and seven patients were partially cured. The efficacy rate was 88.9%, and 38 patients (84.4%) were satisfied with the esthetic result. We describe an efficacious and esthetically satisfactory surgical method for managing facial keloids by preserving the keloid skin as a skin flap.

    Penile enhancement was performed using acellular dermal matrix. Multiple layers of acellular dermal matrix were placed underneath the penile skin to enlarge its girth. Since March 2002, penile augmentation has been performed on 12 cases using acellular dermal matrix. Postoperatively all the patients had a 1.3-3.1 cm (2.6 cm in average) increase in penile girth in a flaccid state. The penis had normal appearance and feeling without contour deformities. All patients gained sexual ability 3 months after the operation. One had a delayed wound healing due to tight dressing, which was repaired with a scrotal skin flap. Penile enlargement by implantation of multiple layers of acellular dermal matrix was a safe and effective operation. This method can be performed in an outpatient ambulatory setting. The advantages of the acellular dermal matrix over the autogenous dermal fat grafts are elimination of donor site injury and scar and significant shortening of operation time.

    Full Text Available Reconstruction of nasal defects must preserve the integrity of complex facial functions and expressions, as well as facial symmetry and a pleasing aesthetic outcome. The reconstructive modality of choice will depend largely on the location, size, and depth of the surgical defect. Individualized therapy is the best course, and numerous flaps have been designed to provide coverage of a variety of nasal-specific defects. We describe our experience in the aesthetic reconstruction of nasal skin defects following oncological surgery. The use of different local flaps for nasal skin cancer defects is reported in 286 patients. Complications in this series were one partial flap dehiscence that healed by secondary intention, two forehead flaps, and one bilobed flap with minimal rim necrosis that resulted in an irregular scar requiring revision. Aesthetic results were deemed satisfactory by all patients and the operating surgeons. The color and texture matches were aesthetically good, and the nasal contour was distinct in all patients. All scars were inconspicuous and symmetrical. No patient had tenting or a flat nose.

    Rates of mastectomy with immediate reconstruction are rising. Skin flap necrosis after this procedure is a recognized complication that can have an impact on cosmetic outcomes and patient satisfaction, and in worst cases can potentially delay adjuvant therapies. Many retrospective studies of this complication have identified variable event rates and inconsistent associated factors. A prospective study was designed to capture the rate of skin flap necrosis as well as pre-, intra-, and postoperative variables, with follow-up assessment to 8 weeks postoperatively. Uni- and multivariate analyses were performed for factors associated with skin flap necrosis. Of 606 consecutive procedures, 85 (14 %) had some level of skin flap necrosis: 46 mild (8 %), 6 moderate (1 %), 31 severe (5 %), and 2 uncategorized (0.3 %). Univariate analysis for any necrosis showed smoking, history of breast augmentation, nipple-sparing mastectomy, and time from incision to specimen removal to be significant. In multivariate models, nipple-sparing, time from incision to specimen removal, sharp dissection, and previous breast reduction were significant for any necrosis. Univariate analysis of only moderate or severe necrosis showed body mass index, diabetes, nipple-sparing mastectomy, specimen size, and expander size to be significant. Multivariate analysis showed nipple-sparing mastectomy and specimen size to be significant. Nipple-sparing mastectomy was associated with higher rates of necrosis at every level of severity. Rates of skin flap necrosis are likely higher than reported in retrospective series. Modifiable technical variables have limited the impact on rates of necrosis. Patients with multiple risk factors should be counseled about the risks, especially if they are contemplating nipple-sparing mastectomy.

    Full Text Available INTRODUCTION : Face represents complete personality of human being. Cosmetically it is very important part of a person especially for woman. There are many situations when due to disease or trauma, facial defect arises, which requires reconstruction by either local or distant surgical flaps . METHODS AND MATERIALS : In rural places, we come across many patients suffering from trauma and skin malignancy of face. These patients require reconstruction done esthetically with local flaps. Objective of this study is to share our exper ience of providing esthetically good results at our secondary referral care center. Hereby, we present case series of 14 patients operated at our institute. These patients were analyzed according to the age, sex, nature of injury and anatomical location of lesion on the face. All these patients were operated and reconstruction of defect was done with various local flaps best suited for respective lesion, under local anesthesia or sedation. Post - operative nature of wound was analyzed for flap viability or fl ap necrosis . RESULTS : Amongst them were 7 male and 7 female, ages ranging from 4 to 80 years. 7out of 14 patients were of basal cell carcinoma, 4 were due to trauma, 2 were due to dog bite and 1 case of recurrent pleomorphic adenoma at root of nose. All patients had excellent flap viability at end of 6 months and flap achieving almost similar color and contour as that of surrounding skin. CONCLUSION : Reconstruction of facial defects by local flaps is very easy and cost effective technique. This can be don e even at secondary referral care centre with minimal availability of facilities

    We review our experience with the management of iatrogenic penile injuries. Apart from circumcision, serious damage to the penis can occur following hypospadias repair, surgery for priapism or total loss of the penis following surgical repair of bladder exstrophy. A retrospective analysis of patients with iatrogenic penile amputation referred to us between 1980 and 2000 was undertaken. Causes of injury and choice of management were reviewed. Of the 13 cases treated during the 20-year period mechanism of primary injury was circumcision in 4, hypospadias repair in 6, priapism in 1, bladder exstrophy repair in 1 and penile carcinoma in 1. A variety of techniques were used for phallic reconstruction. Penile degloving, division of suspensory ligament and rotational skin flaps achieved penile augmentation and enhancement. Reasonable cosmesis and penile length were achieved in all cases. In indicated cases microsurgical phalloplasty was technically feasible. However long-term followup showed various complications including erosions from the use of a penile stiffener. The ultimate goal of reconstructive surgery is to have a penis with normal function and appearance. The management of penile injury requires a wide variety of surgical techniques that are tailored to the individual patient. Expedient penile reconstruction is successful and therapeutic delay is associated with complications.

    Full Text Available Skin tags or acrochordons, commonly observed in the flexural surfaces and various folds of skin, are more frequently encountered in presence of obesity, diagetes and old age. Although lesions are quite characteristic clinically, at times these need to be differentiated from warts, fibromas and other benign tumors of skin and their appendages. A rare case with presence of skin tags over the shaft of penis is described.

    Full Text Available Penile torsion can be congenital and associated with hypospadias and chordee, or can be acquired after circumcision. The incidence of isolated neonatal penile torsion was 1.7 to 27% in the literature. The majority were between 10 and deg; and 20 and deg;. Generally, torsion was to the left in cases. The techniques for correction of penile torsion described in the literature are penile de-gloving and reattaching of skin, resection of Buck's fascia incising the base of the penis and removing angular ellipses of corporeal tissue with subsequent plication of tunica, and dorsal dartos flap rotation in severe cases. In conclusion, penile torsion may be familial. Therefore, brothers should be examined carefully. The degloving and realignment technique is successful in isolated penile torsion.

    A persistent problem in autologous breast reconstruction in skin-sparing mastectomies is skin restoration after skin necrosis or secondary oncological resection. As a solution to facilitate reconstruction, skin banking of free-flap skin has been proposed in cases where the overlying skin envelope must be resected, as this technique spares the patient an additional donor site. Herein, we present the largest series to date in which this method was used. We investigated its safety and the possibility of skin banking for prolonged periods of time. All skin-sparing mastectomies and immediate autologous breast reconstructions from December 2009 until June 2013 at our institution were analysed. We identified 31 patients who underwent 33 free flap reconstructions in which skin banking was performed. Our median skin banking period was 7 days, with a maximum duration of 171 days. In 22.5% of cases, the banked skin was used to reconstruct overlying skin defects, and in 9.6% of cases to reconstruct the nipple-areolar complex. Microbiological and histological investigations of the banked skin revealed neither clinical infections nor malignancies. In situ skin banking, even for prolonged periods of time, is a safe and cost-effective method to ensure that skin defects due to necrosis or secondary oncological resection can be easily reconstructed.

    2010-05-01

    Full Text Available A 10-year-old greyhound-cross dog was presented with a large, chronic skin wound extending over the interscapular region. The substantial skin defect was closed by making use of bilateral axillary skin fold flaps. It was possible to elevate the 2 skin flaps sufficiently to allow them to meet at the dorsal midline and thus facilitate complete closure of a large and awkwardly positioned wound. Small dorsal areas of the skin flaps underwent necrosis, but the resulting defects were closed without difficulty in a subsequent procedure. To the author's knowledge, this is the 1st clinical report of the use of bilateral axillary skin fold flaps in this fashion and describes an additional use of a versatile skin flap procedure.

    Sclerosing lymphangitis of the penis is a benign, under-reported condition consisting of a asymptomatic firm cord-like swelling around the coronal sulcus of the penis usually affecting men in the second or third decade of life. Penile oedema and erosions are rarely reported. Clinical signs may be remarkable contrasting with the self-limited character of the disease. We report a new case of sclerosing lymphangitis of the penis occurring in a 59-year-old patient marked by penile swelling and several overlying skin erosions, and discuss the clinical features and the pathogenesis aspects of the disease. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    More than 30 patients presented for reconstruction of penile deformities secondary to penile enlargement surgery performed by other physicians. Lengthening was performed by releasing the suspensory ligament of the penis and advancing pubic skin with a V-Y advancement flap. Girth was increased by injecting autologous fat. Specific complaints relating to the lengthening procedure involve hypertrophic and/or wide scars, a proximal penile hump from a thick, hair-bearing V-Y flap, and a low hanging penis. Complications relating to autologous fat injections include disappearance of fat, penile lumps and nodules, and shaft deformities. The repair of these deformities is described. From 1994 through October 1996, 19 men underwent 24 various combinations of reconstructive operations, such as scar revisions, V-Y advancement flap reversal, and removal of fat nodules and asymmetrical fat deposits. Penile appearance and function were improved. Complications include 1 hematoma requiring drainage, minor wound complications and 1 inadequately reversed V-Y flap. The methods of various repairs are discussed, including reconstructive limitations, timing and staging. Significant improvement can be achieved with proper reconstruction of penile deformities.

    Objective To study the effect of postoperative radiation on free skin flaps.Methods Twenty-nine patients with free skin flaps applied to the plerosis of the postoperative defectwere followed up. Twenty-eight out of 29 patients received forearm free flaps while 1 had anterolater-al femoris skin flaps in a size ranging from 14 cm× 6 cm to 8 cm× 4 cm. These flaps were exposedto 60Co radiation ranging 40-69 Gy. Results Observation during irradiation: no visible changes ofskin flaps and oral mucous membrane were detected when irradiation dose was within 40 Gy; somechanges may be detected over 40 Gy. Observation 1 - 4 months after irradiation: pigmentations werefound in areas of erosion epidermis; skin flaps got dark but without evidence of necrosis. Observation2 years after irradiation: no necrosis happened in 29 skin flaps. Hairs were found on 15 of 29flaps. Sensation occurred within the margin of 1 cm. Conclusion Free skin flap can endure irradi-ation at the dose of 60 Gy.

    One of the most challenging procedures in breast surgery is the skin-sparing mastectomy (SSM). Various techniques and incisions have evolved that characterize this procedure; however, what is common in all of them is the smaller the incision, the more difficult it is to develop the skin flaps. A procedure was developed that incorporates the use of liposuction cannulas (without suction) to create the skin flaps. The technique and results are described in this manuscript. From October of 2012 to April 2014, 289 mastectomies (171 patients) were performed using the CAFE procedure on women of all shapes and sizes. Postoperatively, no problems were experienced with flap viability using this technique. The main difference in side effects between the CAFE technique and other standard techniques for developing flaps in SSMs was more bruising than normal, but this resolved rapidly. The results for use of this technique were consistently impressive. The learning curve for this procedure is very short, especially for those who perform SSMs using sharp technique (scissors). Residents and fellows became proficient with the CAFE technique in a relatively short amount of time. Plastic surgeons were pleased with the cosmetic outcomes of their reconstructions that follow this type of mastectomy. Patients were extremely satisfied with their reconstructions as well. Incorporating the use of liposuction cannulas (without suction) makes the creation of flaps for SSM a relatively simple and rapid method. It is especially useful to assist in developing skin flaps with even the smallest of skin incisions.

    Full Text Available Abstract Introduction Isolated lymphedema of the penis is extremely rare: combined involvement of the scrotum and penis is the norm. Furunculosis as a cause is not, to our knowledge, previously reported. We present a case of isolated penile lymphedema that responded to excision of lymphedematous tissue and reconstruction with flaps. Case presentation A 32-year-old Arab man presented with a three-year history of a gradually increasing, painless penile swelling. Our patient's main complaint was non-erectile sexual dysfunction. The swelling was preceded by at least three prior episodes of severe furunculosis at the penile root. He had no other contributory past medical or family history. On examination there was gross penile enlargement, maximally at the mid shaft, associated with thickened skin at the sites of prior furunculosis. The glans and scrotum were normal. Both testes were palpable. Serology for filariasis, and urinary tract ultrasound and computed tomography scan were normal. The clinical diagnosis was lymphedema following recurrent penile furunculosis. At operation the lymphedematous tissues were removed. Closure of the penile shaft was accomplished by bilateral advancement of flaps from both ends of the penis. He resumed normal sexual activity one month after surgery. At 12 months, he had a good cosmetic result, with no signs of recurrence. Conclusions Furunculosis at the penile root may result in lymphedema confined to the penile shaft, sparing the scrotum. Excision of abnormal tissue and cover with a skin flap gave excellent cosmetic results, and allowed satisfactory sexual activity.

    This study investigated the effects of hyperbaric oxygen (HBO) and irradiation (RT) on experimental skin flaps in rats under varying conditions. Animals were assigned at random to 1 of 15 groups that represented all possible ordering effects of HBO, RT, and flap, as well as controls that included flap-only, RT-only, and HBO-only groups. Cranially based skin flaps measuring 3 x 9 cm were elevated on the dorsum. The surviving length was evaluated with fluorescein dye 7 days after the operation. Depending on the treatment condition, HBO was given either 48 hours or 24 hours before flap elevation, or within 4 hours or 48 hours after flap elevation. Rats receiving RT ( 60 Co) were given a single dose of 1000 rads to the dorsum. Results showed that all groups receiving HBO within 4 hours after flap elevation had significantly greater flap survival length, with as much as a 22% greater length of surviving flap. HBO given 48 hours before flap elevation also significantly improved flap survival over controls. RT appeared to have no immediate significant effect on flap survival. However, rats receiving RT, regardless of other factors, gained significantly less weight than did controls. Findings clearly indicate that, to be effective, HBO needs to be given as soon after surgery as possible

    To study the influence of estradiol on histomorphology of skin flaps with ischemia reperfusion injury. 48 adult male Wistar rats aged 12-14 weeks old, were randomly divided into control group (group I), ischemia-reperfusion group (group II), saline group (group III), estradiol group (group IV). Superficial epigastric artery axial flap, 3 cm x 6 cm in size, was made in the left lower quadrant abdominal of each rat. Flap model with ischemia-reperfusion injury was established by using the nondestructive micro vascular clamp to clamp the superficial epigastric artery. The general condition of the flap was observed after operation. At 7 days after operation, the survival rate of the flap was detected, the flaps were harvested to receive histology and ultrastructural observation. The neutrophils level of the superficial epigastric vein were tested. 7 days after operation, the survival rate of the flap in group IV was significantly higher than that in group II, III (P organization structure in flap.

    Flap necrosis still is a challenging problem in reconstructive surgery that results in irreversible tissue loss. This study evaluated the effect of topically applied minoxidil on angiogenesis and survival of a caudally based dorsal rat skin flap. For this study, 24 male Wistar rats were randomly divided into three groups of eight each. A caudally based dorsal skin flap with the dimensions of 9 × 3 cm was raised. After elevation of the flaps, they were sutured back into their initial positions. In group 1 (control group), 1 ml of isotonic saline was applied topically to the flaps of all the animals for 14 days. In group 2, minoxidil solution was spread uniformly over the flap surface for 7 days after the flap elevation. In group 3, minoxidil solution was applied topically to the flap surface during a 14-day period. On day 7 after the flap elevation, the rats were killed. The average area of flap survival was determined for each rat. Subdermal vascular architecture and angiogenesis were evaluated under a light microscope after two full-thickness skin biopsy specimens had been obtained from the midline of the flaps. The lowest flap survival rate was observed in group 1, and no difference was observed between groups 1 and 2. Compared with groups 1 and 2, group 3 had a significantly increased percentage of flap survival (P minoxidil is vasodilation and that prolonged use before flap elevation leads to angiogenesis, increasing flap viability.

    The use of microsurgery in the management of burn sequelae is not a new idea. According to the properties of various types of free flaps different goals can be achieved or various additional procedures have to be combined. We report the comparison of two different free flaps on a single patient for reconstruction of both upper extremities for burn sequelae. A 1-year-old child sustained severe burns on both hands, arms and thorax and was initially only treated conservatively. This resulted in severe contractures. At the age of 4-years a free gracilis flap was selected for reconstruction of his left hand and a free anterolateral thigh flap for the right hand. We noticed a better functional and esthetic result for the gracilis flap associated with a shorter operative time and a minor donor site morbidity. The intraoperative technique and time, postoperative complications, functional and esthetic results and donor site morbidities were studied in the two types of flaps chosen. A review of literature was also performed. Our experience reported a better success of the gracilis muscle flap covered with a split skin graft compared to the anterolateral thigh flap in the reconstruction of hand function after severe burn sequelae.

    A high-quality flap is necessary for repairing faciocervical scar contractures. The supraclavicular region and chest wall are the preferred choices for reconstruction. The supraclavicular island flap (SIF) pedicled by the transverse cervical artery (TCA) has been reported. Compared to the traditional SIF flap, another type of flap pedicled by the anterior perforator of transverse cervical artery (ap-TCA) is more convenient for transfer to the faciocervical area. In this article, we use this type of perforator flap and expanded perforator flap to repair the faciocervical contracture. In this study, 10 cases (deformity caused by burn or trauma to the face and neck sites) with an average age of 32 years-old, were treated by ap-TCA flap and this type of expanded flap. In between, the flap was pre-expanded for approximately 3 months prior to transfer in 6 patients. Another 4 cases did not want the expander because of the long duration required for saline filling and potential complications of the expander. Bilateral prefabricated flaps were designed in two female cases. All 12 flaps in 10 patients were transferred tension-free to the defects and no flap was lost. The size of the flap ranged from 12 cm × 8 cm to 15 cm × 20 cm. All 12 flaps survived completely. The donor sites were closed directly in the above 6 patients where an expander had been used and reconstructed by split skin graft in 4 patients where no expander had been employed. Through a mean time of 6 months' follow-up, only one female patient was disappointed with the cicatrix that presented on the upper polar skin of both breasts, the other 9 patients were satisfied with both recipient function and appearance. The color and the texture matched well with the recipient area. The ap-TCA flap and expanded ap-TCA flap can be considered reliable options for faciocervical deformities as it can be easily elevated and it matches well with faciocervical area in color. With regards to the expanded flap, we

    Penile inversion vaginoplasty is considered to be the gold standard for gender reassignment surgery in transgender women. The use of additional full-thickness skin graft as neovaginal lining is controversial. Some believe that having extra penile skin for the vulva gives better aesthetic results. Others believe that it gives inferior functional results because of insensitivity and skin graft contraction. Transgender women undergoing penile inversion vaginoplasty were studied prospectively. The option to add full-thickness skin graft is offered in patients where the penile skin length lies between 7 and 12 cm. Neovaginal depth was measured at surgery and during follow-up (3, 13, 26, and 52 weeks postoperatively). Satisfaction with the aesthetic result, neovaginal depth, and dilation regimen during follow-up were recorded. Satisfaction, sexual function, and genital self-image were assessed using questionnaires. A total of 100 patients were included (32 with and 68 without additional full-thickness skin graft). Patient-reported aesthetic outcome, overall satisfaction with the neovagina, sexual function, and genital self-image were not significantly associated with surgical technique. The mean intraoperative neovaginal depth was 13.8 ± 1.4 cm. After 1 year, this was 11.5 ± 2.5 cm. The largest decline (-15 percent) in depth is observed in the first 3 postoperative weeks (p skin graft use, in penile inversion vaginoplasty. The additional use of full-thickness skin graft does not influence neovaginal shrinkage, nor does it affect the patient- and physician-reported aesthetic or functional outcome. Therapeutic, IV.

    Prefabrication of supraclavicular skin provides a useful source for flaps congruent with the face skin. Among various vascular sources that have been used for this purpose, anterolateral thigh fascia seems to represent a greater value because of having a long and strong vascular pedicle and negligible donor-site morbidity. In this regard, we present a technical report on using the lateral circumflex femoral artery perforator flap harvest technique in preparing an anterolateral thigh fascia flap for the prefabrication of the supraclavicular skin. The technique proved successful in resurfacing the facial skin of a young female patient with a giant congenital melanocytic hairy nevus on the left side of her face.

    Full Text Available Temporal artery calciphylaxis has rarely been described in chronic kidney disease patients on dialysis. We report a case of 72-year-old Caucasian man with multiple comorbidities and end-stage renal disease on dialysis who presented with temporal artery calcification leading to bilateral loss of vision followed by extensive skin lesions including one on glans penis. While on peritoneal dialysis, he developed anterior ischemic optic neuropathy, had no improvement on high dose steroids, and temporal artery biopsy showed marked calcification without any evidence of vasculitis. Few weeks later on hemodialysis, he developed widespread cutaneous lesions on extremities and penile necrosis with skin biopsy revealing calciphylaxis. On literature review of calciphylaxis in chronic kidney disease, we found only four cases of temporal artery calciphylaxis leading to anterior ischemic optic neuropathy and blindness. We believe this is the first case in which the rare temporal artery calciphylaxis and the uncommon penile necrosis are being described together. The objective is to emphasize the need to recognize this condition early in the CKD patients on dialysis presenting with visual symptoms as the different treatment strategies may help prevent complete loss of vision and also modify or prevent a full blown calciphylaxis.

    In the hypospadiac penis the ventral skin is poorly developed, while dorsal skin is redundant. The classical Byars' flaps are a way to use the excess dorsal skin to cover the penile shaft. The appearance after Byars' flaps however is not natural. We use a more natural looking skin allocation with superior aesthetic results. The clue in this reconstruction is an inverted triangle shaped excision of ventral skin expanding over the edges of the hooded prepuce (which makes it look like Batman). After excision of the ventral skin it is possible to close the penile skin in the midline, thus mimicking the natural raphe. In case of preputial reconstruction the excised ventral skin makes the prepuce look more natural. The trend of further refining aesthetic appearance of the hypospadiac penis often neglects the penile skin reconstruction. A technique is presented by which the total penile appearances after surgery ameliorates due to better skin reconstruction.

    Over the last decade, lymph node flap (LNF) transfer has turned out to be an effective method in the management of lymphoedema of extremities. Most of the time, the pockets created for LNF cannot be closed primarily and need to be resurfaced with split thickness skin grafts. Partial graft loss was frequently noted in these cases. The need to prevent graft loss on these iatrogenic wounds made us explore the possibility of attempting delayed skin grafting. We have herein reported our experience with delayed grafting with autologous banked split skin grafts in cases of LNF transfer for lymphoedema of the extremities. Ten patients with International Society of Lymphology stage II-III lymphoedema of upper or lower extremity were included in this study over an 8-month period. All patients were thoroughly evaluated and subjected to lymph node flap transfer. The split skin graft was harvested and banked at the donor site, avoiding immediate resurfacing over the flap. The same was carried out in an aseptic manner as a bedside procedure after confirming flap viability and allowing flap swelling to subside. Patients were followed up to evaluate long-term outcomes. Flap survival was 100%. Successful delayed skin grafting was done between the 4th and 6th post-operative day as a bedside procedure under local anaesthesia. The split thickness skin grafts (STSG) takes more than 97%. One patient needed additional medications during the bedside procedure. All patients had minimal post-operative pain and skin graft requirement. The patients were also reported to be satisfied with the final aesthetic results. There were no complications related to either the skin grafts or donor sites during the entire period of follow-up. Delayed split skin grafting is a reliable method of resurfacing lymph node flaps and has been shown to reduce the possibility of flap complications as well as the operative time and costs. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Extensive degloving injuries of the extremities usually result in necrosis of the flap, necessitating comprehensive skin grafting. Provided there is a sufficient tool to evaluate flap viability, full-thickness skin can be used from a nonviable avulsed flap. We used a Wood's lamp to determine the viability of avulsed flaps in the operation field after intravenous injection of fluorescein dye. We experienced 13 cases during 16 months. Fifteen minutes after the intravenous injection of fluorescein dye, the avulsed skin flaps were examined and non-fluorescent areas were marked under Wood's lamp illumination. The marked area was defatted for full-thickness skin grafting. The fluorescent areas were sutured directly without tension. The non-fluorescent areas were covered by defatted skin. Several days later, there was soft tissue necrosis within the flap area. We measured necrotic area and revised the flap. Among all the cases, necrotic area was 21.3% of the total avulsed area. However, if we exclude three cases, one of a carelessly managed patient and two cases of the flaps were inappropriately applied, good results were obtained, with a necrotic area of only 8.4%. Eight patients needed split-thickness skin grafts, and heel pad reconstruction was performed with free flap. A full-thickness skin graft from an avulsed flap is a good method for addressing aesthetic concerns without producing donor site morbidity. Fluorescein dye is a useful, simple, and cost-effective tool for evaluating flap viability. Avulsed flap injuries can be managed well with Wood's lamp illumination and a full-thickness skin graft.

    Necrosis of random pattern flaps caused by inadequate blood flow, especially in the distal part of the flap is one of the biggest challenges in reconstructive surgery. Various agents have been used to prevent flap ischemia. In this study, we used omeprazole, which is a potent inhibitor of gastric acidity to increase flap viability. In this study, 35 Wistar-Albino type rats which were divided into 5 equal groups were used. Random-pattern dorsal skin flaps were raised in all groups at seventh day of the study. Group 1 was accepted as control group, and the rats in this group was only given distilled water intraperitoneally for 14 days. Group 2 and group 3 received 10 and 40 mg/kg omeprazole daily for 14 days, respectively. Group 4 and group 5 were given distilled water for the first 7 days and then after the operations they received 10 and 40 mg/kg omeprazole daily for 7 days, respectively. Survival rates of the flaps were examined seventh day after elevation of the flaps by digital imaging and scintigraphy. After assessment of the amount of necrosis, number of vascular structures were counted histopathologically. Percentage of flap necrosis was found to be less in all omeprazole received groups. On digital imaging, percentages of flap necrosis in the study groups were statistically significantly lower than that of the control group (P 0.05).In the histopathologic specimens, it was detected that the mean number of vessels in proximal (a) and distal (c) portions of the flap in the study groups showed a significant increase when compared with the control group (P usage of medications increasing gastrin during flap surgeries can be thought as a positive contributor. In this sense, this study showed that parenteral administration of omeprazole in skin flap surgery increases flap viability possibly by increasing gastrin levels.

    To evaluate the clinical outcomes of free perforator flaps combined with skin graft for reconstruction of ankle and foot soft tissue defects. Between June 2014 and October 2015, 20 cases of ankle and foot soft tissue defects were treated. There were 16 males and 4 females, aged from 19 to 61 years (mean, 43.3 years). Injury was caused by traffic accident in 7 cases, by crashing in 9 cases, and machine twist in 4 cases. The locations were the ankle in 6 cases, the heel in 3 cases, the dorsum pedis in 4 cases, and the plantar forefoot in 7 cases of avulsion injury after toes amputation. The size of wound ranged from 15 cm×10 cm to 27 cm×18 cm. The time from injury to treatment was from 11 to 52 days (mean, 27 days). The anterolateral thigh perforator flap was used in 11 cases, thoracodorsal antery perforator flap in 3 cases, medial sural artery perforator flap in 4 cases, deep inferior epigastric perforator flap in 1 case, and anteromedial thigh perforator flap in 1 case, including 5 chimeric perforator flaps, 5 polyfoliate perforator flaps, 3 flow-through perforator flaps, and 3 conjoined perforator flaps. The size of the perforator flap ranged from 10.0 cm×6.5 cm to 36.0 cm×8.0 cm, the size of skin graft from 5 cm×3 cm to 18 cm×12 cm. Venous crisis occurred in 2 flaps which survived after symptomatic treatment; 18 flaps survived successfully and skin grafting healed well. The follow-up time ranged 4-18 months (mean, 8.3 months). The flaps had good appearance, texture and color, without infection. The patients could walk normally and do daily activities. Only linear scars were observed at the donor sites. Free perforator flap can be used to reconstruct defects in the ankle and foot, especially in the weight-bearing area of the plantar forefoot. A combination of free perforator flap and skin graft is ideal in reconstruction of great soft tissue defects in the ankle and foot.

    Full Text Available Background: A soft tissue defect requiring flap cover which is longer than that provided by the conventional "long" free flaps like latissimus dorsi (LD and anterolateral thigh (ALT flap is a challenging problem. Often, in such a situation, a combination of flaps is required. Over the last 3 years, we have managed nine such defects successfully with a free "Boomerang-shaped" Extended Rectus Abdominis Myocutaneous (BERAM flap. This flap is the slightly modified and "free" version of a similar flap described by Ian Taylor in 1983. Materials and Methods: This is a retrospective study of patients who underwent free BERAM flap reconstruction of soft tissue defects of extremity over the last 3 years. We also did a clinical study on 30 volunteers to compare the length of flap available using our design of BERAM flap with the maximum available flap length of LD and ALT flaps, using standard markings. Results: Our clinical experience of nine cases combined with the results of our clinical study has confirmed that our design of BERAM flap consistently provides a flap length which is 32.6% longer than the standard LD flap and 42.2% longer than the standard ALT flap in adults. The difference is even more marked in children. The BERAM flap is consistently reliable as long as the distal end is not extended beyond the mid-axillary line. Conclusion: BERAM flap is simple in design, easy to harvest, reliable and provides the longest possible free skin/myocutaneous flap in the body. It is a useful new alternative for covering long soft tissue defects in the limbs.

The difference is even more marked in children. The BERAM flap is consistently reliable as long as the distal end is not extended beyond the mid-axillary line. BERAM flap is simple in design, easy to harvest, reliable and provides the longest possible free skin/myocutaneous flap in the body. It is a useful new alternative for covering long soft tissue defects in the limbs.

    It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients. Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a 30-mm long piece of skin, while allowing the 5 mm wide distal part of the skin to remain attached, to mimic a skin flap (hereafter called a "skin flap"). Blood perfusion was measured before and after repeated diathermy, using laser speckle contrast imaging. Blood perfusion decreased from the base to the tip of the flap: 5 mm from the base, the perfusion was 69%, at 10 mm it was 40%, at 15 mm it was 20%, and at 20 mm it was only 13% of baseline values. Diathermy further decreased blood perfusion (measured 15 mm from the base) to 13% after applying diathermy for the first time, to 6% after the second and to 4% after the third applications of diathermy. Blood perfusion falls rapidly with distance from the base of skin flaps on the human eyelid, and diathermy reduces blood perfusion even further. Clinically, it may be advised that flaps with a width of 5 mm be no longer than 15 mm (i.e., a width:length ratio of 1:3), and that the use of diathermy should be carefully considered.

    Radiation effects after reconstructive surgery (free-skin grafts and skin flaps) were studied in the rat, and the optimum time for irradiation was determined. The radiosensitivity of both free-skin grafts and skin flaps showed the same trend depending on time of irradiation after operation. The grafts or flaps irradiated in the hypervascular stage showed severe reactions to irradiation, whereas those irradiated in the hypovascular stage showed milder reactions in gross and microangiographic observation. Vascular damage should be given primary consideration when deciding the proper time for irradiation after reconstructive surgery. In general, free-skin grafts showed more severe reactions than skin flaps, especially in the grafts irradiated in the early stage after operation. The experimental results of this study cannot be readily transferred to a clinical setting, but they suggest that postoperative irradiation could be begun 3 to 4 weeks after operation with respect to graft or flap survival, and the results of the clinical cases almost coincide with these experimental results

    The hydrogen clearance technique has been used for many years by investigators to determine brain blood flow and has been partially validated in this setting using other methods of blood flow measurement. The method has been modified to allow blood flow measurements in skin, but the accuracy of H2 clearance for measuring skin blood flow has not been determined. Multiple blood flow measurements were performed using H2 clearance and radioactive microspheres on skin flaps and control skin in pigs. On 12 pigs, a total of 117 flap and 42 control skin measurements were available for analysis. There was no significant difference between the two techniques in measuring mean control skin blood flow. In skin flaps, H2 clearance was significantly correlated to microsphere-measured blood flow, but it consistently gave an overestimate. Sources of error may include injury to the tissues by insertion of electrodes, consumption of H2 by the electrodes, or diffusion of H2 from the relatively ischemic flap to its well-vascularized bed. Further studies are necessary to determine the cause of this error and to measure the technique's accuracy in skeletal muscle and other flaps

    Despite advances in understanding the underlying mechanisms of flap necrosis and improvement in surgical techniques, skin flap necrosis after reconstructive surgery remains a crucial issue. We investigated the efficacy of electroporation-mediated IL-10 gene transfer to random skin flap with an aim to accelerate wound healing and improve skin flap survival. Nine male Wistar rats (300-330 g) were divided in two groups (a) control group (n = 5), only surgery no gene transfer, and (b) experimental group, received electroporation-mediated IL-10 gene transfer 24 h before the surgery as prophylaxis (n = 4). Random skin flap (McFarlane) was performed in both groups. Planimetry, Laser Doppler imaging, and immunohistochemistry were used to evaluate the effect of IL-10 gene transfer between study groups at day 7. Electroporation-mediated IL-10 gene transfer decreased percentage of flap necrosis (p value = 0.0159) and increased cutaneous perfusion compared to the control group (p value = 0.0159). In addition, Spearman's rank correlation showed a significant negative correlation between percentage of flap necrosis and Laser Index (p value = 0.0083, r -0.83, respectively). Furthermore, significantly higher mean CD31 + vessel density was detected in the experimental group compared to the control group (p value = 0.0159). Additionally, semi-quantitative image analysis showed lower inflammatory cell count in experimental group compared to control group (p value = 0.0317). In vivo electroporation-mediated IL-10 gene transfer reduced necrosis, enhanced survival and vascularity in the ischemic skin flap.

    Skin flap procedures are employed in plastic surgery, but failure can lead to necrosis of the flap. Studies have used bone marrow mesenchymal stem cells (BM-MSCs) to improve flap viability. BM-MSCs and acellular amniotic membrane (AAM) have been introduced as alternatives. The objective of this study was to evaluate the effect of BM-MSCs and AAM on mast cells of random skin flaps (RSF) in rats. RSFs (80 × 30 mm) were created on 40 rats that were randomly assigned to one of four groups, including (I) AAM, (II) BM-MSCs, (III) BM-MSCs/AAM, and (IV) saline (control). Transplantation was carried out during the procedure (zero day). Flap necrosis was observed on day 7, and skin samples were collected from the transition line of the flap to evaluate the total number and types of mast cells. The development and the total number of mast cells were related to the development of capillaries. The results of one-way ANOVA indicated that there was no statistically significant difference between the mean numbers of mast cell types for different study groups. However, the difference between the total number of mast cells in the study groups was statistically significant (p = 0.001). The present study suggests that the use of AAM/BM-MSCs can improve the total number of mast cells and accelerate the growth of capillaries at the transient site in RSFs in rats.

    We report on a patient with a recurrence of oral cancer involving a cervical lymph node. The patient's postexcision cervical skin defect was nearly circular in shape, and the size was about 12 cm in diameter. The defect was successfully reconstructed with a boomerang-shaped pectoralis major musculocutaneous flap whose skin paddle included multiple intercostal perforators of the internal mammary vessels. This flap design is effective for reconstructing an extensive neck skin defect and enables primary closure of the donor site with minimal deformity.

    To compare donor site morbidity in patients who have undergone fibula free flap reconstruction in which the skin graft was taken from the expected cutaneous paddle of the fibula with the known complications of the popular technique of obtaining a split-thickness skin graft (STSG) from a secondary donor site. Cohort study. The tertiary care centers at Loma Linda University Medical Center and University of California, Los Angeles, Medical Center. From September 1, 2006, to March 30, 2007, 30 patients underwent fibula free flap harvest by 2 surgeons at separate tertiary care centers. Twenty-one of those procedures took place at the University of California, Los Angeles, and 9 at Loma Linda University. Patients included 15 men (50%) and 15 women (50%), with a mean age of 58 (range, 19-88) years. All 30 patients underwent fibula free flap harvest with a split-thickness skin graft (graft thickness, 0.04 cm), obtained from osteocutaneous paddle using a 5.1-cm-wide dermatome, as well as oral cavity and oropharyngeal reconstruction with the de-epithelialized skin paddle. Measures of donor site morbidity, including graft failure and wound breakdown, and measures of recipient site morbidity, including flap failure, hardware complications, intraoral complications, and the need for additional surgery. Of the 30 patients who underwent this procedure, 4 had partial skin graft failures, for a complete skin graft survival of 87%. There were no complete skin graft losses. Regarding the fibula osteocutaneous free flap, there were no complete flap losses, 1 skin paddle necrosis that required debridement, 2 postoperative orocutaneous fistulas, 1 case of infected/extruded hardware, and 1 adhesion formation that required additional surgery for lysis of adhesion and placement of the split-thickness skin graft. The outlined novel technique has similar rates of free flap survival and skin graft take compared with previously described methods. Harvesting the skin graft over the expected

    The conventional procedure of the sural neuro-fasciocutaneous flap enables the supply of blood and venous drainage by increasing the width of the adipofascial tissue and preserving tiny venous return routes. Moreover, skin graft is a common method for donor site closure, which may lead to some complications and influence the aesthetic appearance. We report modifications for a distally based sural neuro-fasciocutaneous perforator flap and a relaying flap for donor site closure without skin graft. Twelve patients undergoing the modified flap for foot and ankle reconstruction were included in this study between 2014 and 2016. A peroneal-based perforator, a superficial vein, and the vascular axis of the sural nerve were included in the pedicle. A Z-shape skin incision was performed to explore the perforator vessels and a relaying island perforator flap was used to close the donor site. All flaps survived completely without necrosis. The area of the flaps ranged from 16 × 8 cm to 30 × 15 cm. The diameter width of the pedicle ranged from 1.0 to 2.0 cm. A relaying perforator island flap was used in 10 cases for donor site closure and no skin graft was performed. There were no serious donor site complications. All patients were satisfied with the aesthetic outcome postoperatively at the final follow-up. The distally based sural neuro-fasciocutaneous perforator flap is considered a reliable method for foot and ankle reconstruction. The modification for flap pedicle and donor site closure method without skin graft should be recommended. Copyright © 2017. Published by Elsevier Ltd.

    The achievement of a normal-appearing face after surgical resurfacing remains an elusive goal. This is due in part to insufficient color matching, restoration of contours, and the persistence of visible scars. Flap prefabrication is a staged procedure that provides an independent axial blood supply to local expanded tissues. We describe a new reconstructive alternative with superior reconstructive surgical options for facial resurfacing that better matches damaged or discarded facial tissues. A superficial temporal fascial flap was harvested as the vascular supply of the prefabricated neck flap and located in a subcutaneous neck pocket over a tissue expander. After a 5-month period for expansion and maturation, the prefabricated skin flap was raised, islanded, and rotated to resurface the facial defect. Four patients with hemifacial postburn contracture and two patients affected by hemifacial vascular malformations aged 17 to 42 years (mean 29 years) were successfully treated with no major complication after a mean period of 15 months. Prefabricated neck-expanded skin flap demonstrated an excellent color and texture match with facial skin that surrounded the repair sites, and optimal aesthetic results were obtained. Importantly, facial expression was completely maintained due to thinness and pliability of the rotated skin. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Full Text Available Objective: A variety of nasal skin reconstruction methods are available to meet the esthetic patient's needs. In this article, we review some of modifications of these procedures and share our experience in reconstruction of different parts of the nasal skin following skin tumor ablation. Patients and Methods : From January 2010 to January 2014, 171 patients underwent nasal skin reconstruction after excising cancerous lesions of the involved nasal skin. The patient's history, pre- and post-operation photographs, and the surgery data were collected and assessed. Demographic data related to the type of cancer, defect size and location, type of reconstruction were collected. Results: A variety of local flaps were used based on location and defect features. Nearly all flaps healed primarily without postsurgical significant complications. Conclusion: According to the results and the outcomes of the operations, we concluded that a certain flaps are more effective than others in nasal skin reconstruction. Local flap reconstruction of the nose has good esthetic result with low complication rate.

    Electronic cigarettes (e-cigarettes) have become increasingly popular. However, information about the health risks associated with e-cigarette use is sparse. Currently, no published studies examine the effects of chronic e-cigarette exposure on microcirculation or perfusion. Using a rat skin flap model, we examined the toxic microcirculatory effects e-cigarettes may have in comparison with tobacco cigarettes. Fifty-eight rats were randomized to either exposure to room air, tobacco cigarette smoke, medium-nicotine content (1.2%) e-cigarette vapor, or a high-nicotine content (2.4%) e-cigarette vapor. After 4 weeks of exposure, a random pattern, 3 × 9 cm skin flap was elevated on the dorsum of the rats. At 5 weeks, flap survival was evaluated quantitatively, and the rats were euthanized. Plasma was collected for nicotine and cotinine analysis, and flap tissues were harvested for histopathological analysis. Evaluation of the dorsal skin flaps demonstrated significantly increased necrosis in the vapor and tobacco groups. The average necrosis within the groups was as follows: control 19.23%, high-dose vapor 28.61%, medium-dose vapor 35.93%, and tobacco cigarette 30.15%. Although the e-cigarette and tobacco cigarette groups did not differ significantly, each individual group had significantly more necrosis than the control group (Pe-cigarette exposure groups had similar amounts of flap necrosis and hypoxia when compared with the tobacco cigarette exposure group. Nicotine-containing e-cigarette vapor is similarly toxic to skin flap survival as tobacco cigarettes.

    Full Text Available Introduction Fournier’s gangrene is a poly-microbial necrotizing fasciitis that involves the perineum and/or external genitalia. Urgent surgical debridement is well recognized as essential acute treatment yet unique challenges arise for plastic surgical reconstruction to obtain a complete functional recovery. This case describes a successful delayed pedicle flap repair based upon the anterior abdominal wall. Case description A 24 year old man was admitted to ICU ten days after elective circumcision with Fournier’s gangrene. He underwent a number of surgical debridements, and was referred for plastic surgical management. He had penile reconstruction using a random pattern abdominal flap, which was performed as a three stage procedure including flap vascular delay technique. Discussion Perineal and penile skin loss can be significant and is difficult to repair. Various techniques have been used to reconstruct lost tissue: skin grafts, transposition of the testes and spermatic cords to the thigh, flaps, and other types of pediculated myocutaneous flaps. Muscle flap reconstruction provides an environment that allows for complete regeneration of the urethral epithelium but is bulky and unsightly. Skin grafts contract and may produce painful and dysfunctional reconstructions. This novel technique produces a functional, and aesthetic reconstruction. Conclusion Penile skin recovery following Fournier’s gangrene recovery is problematic. This case demonstrates the functionality of a delayed flap repair using the anterior abdominal wall.

    A suitable pharmacological substitute for the well-established surgical delay technique for random skin flaps to increase viability has been elusive. To evaluate the effects of nitroglycerin and botulinum toxin type A on random flap survival in a rat model. The present controlled experimental study was performed in the four groups of rats. One week after intervention in each group, the flap was raised and kept in situ, and flap necrosis was evaluated through follow-up. Group 1 received intradermal botulinum toxin type A (BTX-A) and topical nitroglycerin 2%; group 2 received BTX-A and topical Vaseline (Unilever, USA); group 3 received topical nitroglycerin and intradermal normal saline; and group 4 received topical Vaseline and intradermal normal saline. BTX-A reduced the area of necrosis compared with control (24% versus 56% respectively; P<0.001). Nitroglycerin application was associated with a trend toward improved flap viability (42% versus 56%; P=0.059). The combination of topical nitroglycerin and BTX-A, compared with Vaseline and BTX-A, was associated with decreased flap necrosis (16.1% versus 24%, respectively), although it was not statistically significant (P=0.45). BTX-A was effective in reducing distal flap necrosis. The effect of BTX-A was significantly more pronounced than nitroglycerin ointment.

    Cellular function and blood flow in acute, steroid-treated, and surgically delayed random skin flaps have been examined. In these studies, the period following flap elevation could be divided into early (0-2 hr), intermediate (4-6 hr), and late (12 hr) periods of ischemia, based on the cutaneous blood flow and cellular function measured by thallium-201 uptake. There was a close correlation between blood flow and cellular function during the early period of ischemia which became worse with time. Blood flow studies demonstrated a significant difference between the early and intermediate periods of ischemia which was abolished by surgical delay. Improvement in cellular function was accomplished by improved blood flow in the surgically delayed flaps, while steroid-treated flaps enhanced cellular metabolism by another mechanism. Cellular function approximated blood flow during the early and immediate period of ischemia. Steroids may augment cellular function without improving blood flow, while surgical delay improves cellular function by improving blood flow

    Full Text Available BackgroundAfter skin tumor excision on the face, extremities, or trunk, the choice of treatment for a skin defect is highly variable. Many surgeons prefer to use a local flap rather than a skin graft or free flap for small- or moderately-sized circular defects. We have used unilateral or bilateral V-Y advancement flaps, especially on the face. Here we evaluated the functional and aesthetic results of this technique.MethodsAll of the patients were pathologically diagnosed with squamous cell carcinoma (SCC, basal cell carcinoma (BCC, or malignant melanoma or premalignant lesion (Bowen's disease. Thirty-two patients underwent V-Y advancement flap repair (11 unilateral and 21 bilateral from January 2007 to June 2011. We analyzed the patients' age and satisfaction, and location and size of defect. The patients were followed up for 6 months or more.ResultsThere were 22 women and 10 men. The ages ranged from 47 to 93 years with a mean age of 66 years. The causes were SCC in 15 cases, BCC in 13 cases, malignant melanoma in 1 case, Bowen's disease in 2 cases, and another cause in 1 case. The tumor locations were the face in 28 patients, and the scalp, upper limb, and flank each in one patient. All of the flaps survived and the aesthetic results were good. Postoperative recovery was usually rapid, and no complication or tumor recurrence was observed.ConclusionsThe V-Y advancement flap is often used not only for facial circular defects but also for defects of the trunk and extremities. Its advantages are less scarring and superior aesthetic results as compared with other local flap methods, because of less scarification of adjacent tissue and because it is an easy surgical technique.

    We investigated the skin blood flow in five types of delayed deltopectoral flaps and the optimal time for transfer after delay operation using the local clearance method of Xenon-133. The results obtained are reported. 1) Characteristic differences were observed in recovery patterns of the distal blood flow among the five types of delay procedure. 2) The recovery in the distal blood flow of the D-P flap lined with a split-skin graft appeared the fastest among the five types, followed by the tubed D-P flap. 3) When using a bipedicled D-P flap, lateral incision should be performed within 10 days after delay procedure. 4) The skin blood flow of less than 5 ml/100g/min indicated a high risk of necrosis of the deltopectoral flap. 5) The optimal time for transfer was found to be when the skin blood flow of the distal region recovered to the control level.

    Objective: Technological advances have provided new alternatives to the analysis of skin flap viability in animal models; however, the interrater validity and reliability of these techniques have yet to be analyzed. The present study aimed to evaluate the interrater validity and reliability of three different methods: weight of paper template (WPT), paper template area (PTA), and photographic analysis. Approach: Sixteen male Wistar rats had their cranially based dorsal skin flap elevated. On the seventh postoperative day, the viable tissue area and the necrotic area of the skin flap were recorded using the paper template method and photo image. The evaluation of the percentage of viable tissue was performed using three methods, simultaneously and independently by two raters. The analysis of interrater reliability and viability was performed using the intraclass correlation coefficient and Bland Altman Plot Analysis was used to visualize the presence or absence of systematic bias in the evaluations of data validity. Results: The results showed that interrater reliability for WPT, measurement of PTA, and photographic analysis were 0.995, 0.990, and 0.982, respectively. For data validity, a correlation >0.90 was observed for all comparisons made between the three methods. In addition, Bland Altman Plot Analysis showed agreement between the comparisons of the methods and the presence of systematic bias was not observed. Innovation: Digital methods are an excellent choice for assessing skin flap viability; moreover, they make data use and storage easier. Conclusion: Independently from the method used, the interrater reliability and validity proved to be excellent for the analysis of skin flaps' viability.

    Cryptotia is a common congenital ear deformity in Asian populations. In cryptotia, a portion of the upper ear is hidden and fixed in a pocket of the skin of the mastoid. Here we describe our method for cryptotia correction by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. We developed a new method for correcting cryptotia by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. Following ear release, the full-thickness skin rotation flap is rotated into the defect, and the donor site is covered with an ultra-delicate split-thickness skin graft raised in continuity with the flap. All patients exhibited satisfactory release of cryptotia. No cases involved partial or total flap necrosis, and post-operative outcomes using this new technique for cryptotia correction have been more than satisfactory. Our method of using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap to correct cryptotia is simple and reliable.

    To discuss the effect of coupled external fixator and skin flap transposition on exposed and nonunion bones. The data of 12 cases of infected nonunion and exposed bone following open fracture treated in our hospital during the period of March 1998 to June 2008 were analysed. There were 10 male patients, 2 female patients, whose age were between 19-52 years and averaged 28 years. There were 10 tibial fractures and 2 femoral fractures. The course of diseases lasted for 12-39 months with the mean period of 19 months. All the cases were treated by the coupled external fixator and skin flap transposition. Primary healing were achieved in 10 cases and delayed healing in 2 cases in whom the tibia was exposed due to soft tissue defect and hence local flap transposition was performed. All the 12 cases had bony union within 6-12 months after operation with the average time of 8 months. They were followed up for 1-3 years and all fractures healed up with good function and no infection recurrence. The coupled external fixator and skin flap transposition therapy have shown optimal effects on treating infected, exposed and nonunion bones.

    Full Text Available BACKGROUND: Cyclooxygenase-2(COX-2 inhibitors provide desired analgesic effects after injury or surgery, but evidences suggested they also attenuate wound healing. The study is to investigate the effect of COX-2 inhibitor on random skin flap survival. METHODS: The McFarlane flap model was established in 40 rats and evaluated within two groups, each group gave the same volume of Parecoxib and saline injection for 7 days. The necrotic area of the flap was measured, the specimens of the flap were stained with haematoxylin-eosin(HE for histologic analysis. Immunohistochemical staining was performed to analyse the level of VEGF and COX-2 . RESULTS: 7 days after operation, the flap necrotic area ratio in study group (66.65 ± 2.81% was significantly enlarged than that of the control group(48.81 ± 2.33%(P <0.01. Histological analysis demonstrated angiogenesis with mean vessel density per mm(2 being lower in study group (15.4 ± 4.4 than in control group (27.2 ± 4.1 (P <0.05. To evaluate the expression of COX-2 and VEGF protein in the intermediate area II in the two groups by immunohistochemistry test .The expression of COX-2 in study group was (1022.45 ± 153.1, and in control group was (2638.05 ± 132.2 (P <0.01. The expression of VEGF in the study and control groups were (2779.45 ± 472.0 vs (4938.05 ± 123.6(P <0.01.In the COX-2 inhibitor group, the expressions of COX-2 and VEGF protein were remarkably down-regulated as compared with the control group. CONCLUSION: Selective COX-2 inhibitor had adverse effect on random skin flap survival. Suppression of neovascularization induced by low level of VEGF was supposed to be the biological mechanism.

    Full Text Available Background: Skin flaps are commonly used in soft-tissue reconstruction; however, necrosis can be a frequent complication. Several systemic and local agents have been used in attempts to improve skin flap survival, but none that can prevent flap necrosis have been identified. Aims: This study aims to determine whether the use of systemic Rosmarinus officinalis (R. officinalis extract can prevent flap necrosis and improve skin flap recovery. Study Design: Animal experimentation. Methods: Thirty-five Wistar albino rats were divided in five groups. A rectangular random-pattern flaps measuring 8×2 cm was elevated from the back of each rat. Group I was the control group. In Group II, 0.2 ml of R. officinalis oil was given orally 2h before surgery. R. officinalis oil was then applied orally twice a day for a week. In Group III, R. officinalis oil was given orally twice a day for one week before surgery. At the end of the week, 0.2 mL of R. officinalis oil was given orally 2 h before surgery. In Group IV, 0.2 mL of R. officinalis oil was injected subcutaneously 2 h before surgery. After the surgery, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week. In Group V, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week prior to surgery. At the end of the week, one last 0.2 mL R. officinalis oil injection was administered subcutaneously 2 h before surgery. After the surgery, 0.2 mL R. officinalis oil was injected subcutaneously twice a day for one week. Results: The mean percentage of viable surface area was significantly greater (p<0.05 in Groups II, III, IV, and V as compared to Group I. Mean vessel diameter was significantly greater (p<0.05 in Groups II, III, IV, and V as compared to Group I. Conclusion: We have determined that, in addition to its anti-inflammatory and anti-oxidant effects, R. officinalis has vasodilatory effects that contribute to increased skin flap survival.

    Radial forearm free flap is the most reliable flap for intraoral soft tissue reconstruction after cancer ablation surgery. However, unesthetic scar of the donor site and the need for a second donor site for skin graft are major disadvantages of the forearm flap. The purpose of this study was to report the clinical results of double-layered collagen graft to the donor site of the forearm free flap without skin graft. Twenty-two consecutive patients who underwent oral cancer ablation and forearm reconstruction between April 2010 and November 2013 were included in this study. Male to female ratio was 12:10, and average age was 61.0 years old (27-84). Double-layered collagen was grafted to the donor site of the forearm free flap and healed for secondary intention. Upper silicone had been trimmed at the periphery during secondary intention, and dry dressing was used. Postoperative scar healing and esthetic results and function were evaluated. An average follow-up period was 34.9 months. The scar area was decreased to 63.9 % in average. The complete healing was obtained between 1.5 and 3 months according to the defect size. There was no functional defect or impairment 3 months after operation. All patients were satisfied with the esthetic results. Three patients died of recurred cancer. Double-layered collagen graft was successfully performed in this study. Without the thigh skin graft, patients had experienced less painful postoperative healing periods and discomfort.

    The classic forehead flaps, which are designed vertically, two-staged and exteriorised pedicled peninsular flaps, are still a reconstructive option for nasal and periorbital defects. However, some drawbacks such as conspicuous donor-site scar, multi-staged procedure, rather short pedicle, hairy appearance (in narrow foreheads), and inability to use the forehead flap when the donor site is involved are often encountered during surgery. To avoid these issues, three unusual designs of the forehead flap are presented, and also a new algorithm is proposed to guide surgeons in their solutions. Nineteen patients (10 women and nine men) were managed with 21 forehead flaps to restore the nasal, medial canthal and frontal defects caused by skin tumours. The flaps were applied as interpolation island, V-Y island, and transverse peninsular designs in 12, four and three patients, respectively. All donor sites were closed primarily except one, where a split thickness skin graft was used. The average follow-up was 14 months. All flaps survived (totally) but in one partial necrosis developed. Aesthetic and functional recoveries were acceptable in all patients. Based on the algorithm presented, the forehead flaps with their superb anatomic characteristics including rich vascular supply and pliable skin can be safely used in either classic or extraordinary fashion for small to medium sized defects of the nasoorbital and frontal regions.

    Full-thickness skin loss is a challenging problem due to limited reconstructive options, demanding 75 million surgical procedures annually in the United States. Autologous skin grafting is the gold standard treatment, but results in donor-site morbidity and poor aesthetics. Numerous skin substitutes are available on the market to date, however, none truly functions as full-thickness skin due to lack of a vascular network. The creation of an autologous full-thickness skin analogue with a vascular pedicle would result in a paradigm shift in the management of wounds and in reconstruction of full-thickness skin defects. To create a clinically relevant foundation, we generated an acellular skin flap scaffold (SFS) with a perfusable vascular pedicle of clinically relevant size by perfusion decellularization of porcine fasciocutaneous flaps. We then analyzed the yielded SFS for mechanical properties, biocompatibility, and regenerative potential in vitro and in vivo. Furthermore, we assessed the immunological response using an in vivo model. Finally, we recellularized the vascular compartment of an SFS and reconnected it to a recipient's blood supply to test for perfusability. Perfusion decellularization removed all cellular components with preservation of native extracellular matrix composition and architecture. Biaxial testing revealed preserved mechanical properties. Immunologic response and biocompatibility assessed via implantation and compared with native xenogenic skin and commercially available dermal substitutes revealed rapid neovascularization and complete tissue integration. Composition of infiltrating immune cells showed no evidence of allorejection and resembled the inflammatory phase of wound healing. Implantation into full-thickness skin defects demonstrated good tissue integration and skin regeneration without cicatrization. We have developed a protocol for the generation of an SFS of clinically relevant size, containing a vascular pedicle, which can be

    To find the properties in the oscillatory components of the cutaneous blood flow on the successful free flap, a wavelet transform was applied to the laser Doppler flowmetry (LDF) signals which were measured simultaneously on the surfaces of the free latissimus dorsi myocutaneous flap and on the adjacent intact skin of the healthy limb, of 18 patients. The frequency interval from 0.0095 to 1.6 Hz was examined and was divided into five subintervals (I: 0.0095-0.021 Hz; II: 0.021-0.052 Hz; III: 0.052-0.145 Hz; IV: 0.145-0.6 Hz and V: 0.6-1.6 Hz) corresponding to endothelial metabolic, neurogenic, myogenic, respiratory and cardiac origins. The average amplitude and total power in the frequency range 0.0095-1.6 Hz as well as within subintervals I, II, IV and V were significantly lower for signals measured on the free flap than those obtained in the healthy limb. However in interval III, they were significantly higher. The normalized spectral amplitude and power in the free flap were significantly lower in only two intervals, I and II, yet in interval III they were significantly higher; no statistical significance was observed in intervals IV and V. The distinctive finding made in this study, aside from the decrease of endothelial metabolic processes and sympathetic control, was the significant increase of myogenic activity in the free flap. It is hoped that this work will contribute towards knowledge on blood circulation in free flaps and make the monitoring by LDF more reliable

    From 1988 to 2005, 8 men who presented with penoscrotal elephantiasis underwent penile shaft degloving and reduction scrotoplasty, followed by transplantation of a split-thickness skin graft (STSG) to the penile shaft. The etiology of elephantiasis in these patients included self-injection of viscous fluid and postsurgical obstructive lymphedema. In the 6 most recent cases, negative-pressure dressings were applied over the STSG to promote graft take, and STSG take rate was 100%. The results of our series corroborate those of a previous report, which showed circumferential negative-pressure dressings to be safe and efficacious in bolstering STSGs to the penile shaft. Furthermore, these results suggest that the use of negative-pressure dressings may improve graft take in this patient population.

    Random skin flaps are commonly used for wound repair and reconstruction. Electroacupuncture at The Zusanli point could enhance microcirculation and blood perfusion in random skin flaps. To determine whether electroacupuncture at The Zusanli point can improve the survival of random skin flaps in a rat model. Thirty-six male Sprague Dawley rats were randomly divided into 3 groups: control group (no electroacupuncture), Group A (electroacupuncture at a nonacupoint near The Zusanli point), and Group B (electroacupuncture at The Zusanli point). McFarlane flaps were established. On postoperative Day 2, malondialdehyde (MDA) and superoxide dismutase were detected. The flap survival rate was evaluated, inflammation was examined in hematoxylin and eosin-stained slices, and the expression of vascular endothelial growth factor (VEGF) was measured immunohistochemically on Day 7. The mean survival area of the flaps in Group B was significantly larger than that in the control group and Group A. Superoxide dismutase activity and VEGF expression level were significantly higher in Group B than those in the control group and Group A, whereas MDA and inflammation levels in Group B were significantly lower than those in the other 2 groups. Electroacupuncture at The Zusanli point can effectively improve the random flap survival.

    Breast prostheses exposure is probably the most devastating complication after a skin sparing mastectomy (SSM) and implant-based, one-stage, breast reconstruction. This complication may occur in the immediate post-operative period or in the weeks and even months after the procedure. In most cases, the cause is poor skin coverage of the implant due to skin necrosis. Eight consecutive cases of implant exposure (or risk of exposure) due to skin necrosis in SSM patients over a period of 5 years, all patients were treated using a random epigastric rotation flap, executed by the same medical team. A random epigastric flap (island or conventional rotation flap) was used to cover the skin defect. All the patients completed the procedure and all prostheses were saved; there were no cases of flap necrosis or infection. Cases of skin necrosis after SSM and immediate implant reconstruction, in which the implant is at risk of exposure, can be successfully treated with a random epigastric rotation flap.

    Surgery for reconstruction of defects after surgery should be performed selectively and the many points must be considered. The authors conducted this study to compare the local flap and skin graft by facial location in the reconstruction after resection of facial skin cancer. The authors performed the study in patients that had received treatment in Department of Plastic Surgery, Gyeongsang National University. The cases were analyzed according to the reconstruction methods for the defects after surgery, sex, age, tumor site, and tumor size. Additionally, the authors compared differences of aesthetic satisfaction (out of 5 points) of patients in the local flap and skin graft by facial location after resection of facial skin cancer by dividing the face into eight areas. A total of 153 cases were confirmed. The most common facial skin cancer was basal cell carcinoma (56.8%, 87 cases), followed by squamous cell carcinoma (37.2%, 57 cases) and bowen's disease (5.8%, 9 cases). The most common reconstruction method was local flap 119 cases (77.7%), followed by skin graft 34 cases (22.3%). 86 patients answered the questionnaire and mean satisfaction of the local flap and skin graft were 4.3 and 3.5 ( p =0.04), respectively, indicating that satisfaction of local flap was significantly high. When comparing satisfaction of patients according to results, local flap shows excellent effects in functional and cosmetic aspects would be able to provide excellent results rather than using a skin graft with poor touch and tone compared to the surrounding normal skin.

    This study was carried out to minimize the incidence of pharyngocutaneous fistula (PCF) following salvage laryngeal surgery using vascularized pedicle pectoralis major myocutaneous flap (PMMC) for enhancing wound healing, rapid intake of oral feeding, reconstruction of desqauamated irradiated skin, achieving short hospital stay and protection against catastrophic blow out mortality. Patients and Methods: This case series study of sixteen patients carried out from May 2005 to July 2009, at the National Cancer Institute, Cairo University where we applied PMMC flap in salvage laryngeal surgery for those with high risk to develop complications: Patients of poor general conditions (anemia, hypoproteinaemia, diabetics) and/or poor local conditions for healing (irradiated neck, extensive local or nodal recurrence with skin desquamation, infiltration or tumor fungation which need extensive resection). Five cases had been treated with primary cobalt radiotherapy laryngeal field only and 4 cases laryngeal field with draining neck nodes, while photon therapy was given in 4 cases as laryngeal field only and 3 cases laryngeal field with draining neck nodes. All cases were squamous cell carcinoma (13 cases grade 2, 2 cases grade 3 and one case grade 1) proved before radiotherapy. Supraglottic recurrence was detected in 7 cases (43.75%) and glottis in 9 cases (56.25%). Following salvage surgery, 11 cases were staged T3 NO, Nl and N2, 3 cases were T2 NO or Nl and 2 cases were T4 N2 with skin infiltration. Tracheostomy was there in 4 cases. Results: The study included fifteen males (93.75%) and one female (6.25%), age was between 38-73 years (mean=55.5 years). Five cases were operated on as total laryngectomy with excision of skin flaps + PMMC flap, 4 cases as total laryngectomy with skin flap excision + functional block neck dissection + PMMC flap and 7 cases as total laryngectomy -f block neck dissection with skin, excision (modified radical in 4 cases and radical in 3 cases

    Synchronous double oral cancer represents the minority of cases of head and neck cancer. After tumor ablation, 2 separate oromandibular defects, even combined with a through-and-through oral defect, pose a serious reconstructive challenge. The ideal method for reconstruction remains controversial. Based on the peroneal vessel axis, a chimeric double-skin paddle peroneal fasciocutaneous or fibular osteomyocutaneous flap could be designed to accomplish the difficult reconstruction. Six male patients, each with 2 separate oromandibular defects after tumor ablation of synchronous double oral cancer, received double-skin paddle flap reconstruction with 3 peroneal fasciocutaneous and 3 fibular osteomyocutaneous flaps. All 6 flaps survived; however, complications included 1 skin paddle lost due to insufficient perfusion of a visible perforator, and 1 superficial necrosis occurring over the tip of a longer skin paddle. One postoperative intraoral infection and 1 donor site infection were also reported. During follow-up, 3 months later, 1 patient succumbed to local recurrence and bony metastasis. One patient developed a new cancer in the maxillary gingiva, and another had osteoradionecrosis 8 months later. Four patients gained acceptable cosmesis with good oral competence. A chimeric flap based on the peroneal artery could provide a segment of fibular bone, 1 or 2 skin paddles, and a cuff of the flexor hallucis longus muscle simultaneously. For 1-stage reconstruction of separate oromandibular defects after tumor ablation of synchronous double oral cancer, this design could provide all components at 1 transfer.

    Background: Hyperbaric oxygenation has been used for various purposes, but its clinical application is limited due to its pulmonary toxicity. We evaluated the therapeutic value of normobaric hyperoxygenation (NBO) for vascularized and nonvascularized tissue transplantation. Methods: Tissue oxygen partial pressure (PtO2) was measured for various organs in mice under inspiratory oxygen of 20%, 60%, or 100%. A rectangular skin flap (1 × 4 cm) or a composite skin graft (2 × 2 cm) was made on the back of mice, which were housed under 20% or 60% oxygen for the first 3 days after surgery. Cell survival was also examined in organ culture skin samples. Results: PtO2 varied among tissues/organs, but increased depending on inspiratory oxygen concentration in all tissues/organs. Although NBO with 100% O2 was toxic, NBO with 60% O2 was safe even when used continuously for a long period. NBO did not significantly improve survival of the rectangular skin flap. On the other hand, in the composite skin graft model, the engraftment area increased significantly (52 ± 10 at 20% vs 68 ± 5.1 at 60%) and contraction decreased significantly (42 ± 8.0 at 20% vs 27 ± 5.7 at 60%). Organ culture of a composite skin sample showed significant cell death under lower oxygen concentrations, supporting the data in vivo. Conclusions: The composite graft was maintained until revascularization by plasmatic diffusion from surrounding tissues, in which PtO2 was improved by NBO. NBO may be an effective adjunct therapy that can be performed readily after nonvascularized tissue grafting. PMID:25289345

    Purpose: To treat squamous cell and basal cell carcinoma of the skin with the Freiburg flap applicator using a high dose rate modality of an Elekta Flexitron or MicroSelectron for radiation delivery by compensating the dose deviation resulting from the incomplete scatter environment. Methods: Patients were selected to have lesions greater than or equal to 2cm. A mask might be needed depending on special locations. The lesions on the eyelid and face presented in this research were, however, treated without a mask. Cutting the flap into a shape conformal to the target and attaching it to the mask were used in order to make the treatment reproducible. Patients were scanned with a Philips Big Bore Brilliant CT. A 1cm margin was added to the lesion. An Elekta Oncentra Brachy treatment planning system ver. 4.3 was used for treatment planning. 40 Gy in 10 or 8 fractions was prescribed to the 1cm depth. The Freiburg flap was aligned and verified by CT scanning prior to treatment. Results: Three patients with squamous cell and basal cell carcinoma of the skin were treated with the Freiburg flap applicator. Lesion sizes ranged from 2cm to 6 cm in a maximum dimension. With treatment planning, we made a dose correction for compensating the dose deviation resulting from the incomplete scatter environment of the flap applicators exposed to air. The flap was also covered by a 4cm bolus in order to obtain more back scattered radiation during treatment. Six month follow up showed a very good cosmetic result. Conclusion: The Freiburg flap brachytherapy offers a non-invasive skin cancer treatment with a high skin dose delivered to the tumor while a low dose sparing the surrounding health tissue. It is a promising alternative to skin cancer surgery or external beam radiation therapy.

    Skin flap necrosis after mastectomy can be a devastating complication significantly affecting patient outcomes. Routine vascular analysis (fluorescein or laser angiography) of mastectomy skin flaps in all patients has been advocated but is of questionable cost-effectiveness. The purpose of this study was to identify the incidence and causative risk factors for mastectomy skin flap necrosis and thereby calculate the fiscal reality of intraoperative vascular screening. This is an institutional review board-approved retrospective study of all patients from 2007 to 2013 who underwent mastectomy related to breast cancer. Skin flap necrosis was defined as major if it necessitated return to the operating room. Data analysis was done for determination of causative factors of necrosis, including age, body mass index, smoking, previous irradiation, coronary artery disease, chronic obstructive pulmonary disorder, hypertension, gastroesophageal reflux disease, hyperlipidemia, obstructive sleep apnea, asthma, diabetes, thyroid disease, history of lumpectomy, and breast reduction or augmentation. During this time, intraoperative vascular screening was not done. Five hundred eighty-one patients underwent 616 mastectomies with a total of 34 necrotic events (5.5%)-16 major and 18 minor. Analyses via Student t tests, univariate analyses, χ testing, and logistic regression showed that history of smoking was the only patient factor associated with postoperative necrosis (P = 0.008). More frequently represented in the necrosis group, but without statistical significance, are previous lumpectomy (P = 0.069) and immediate reconstruction (P = 0.078).For the entire study period, the actual cost to the hospital for major necrotic events was $7,123.10 or $445.19 for each of the 16 major necrotic events and $209.50 for all 34 necrotic events. Per-patient cost-effective screening would need to be less than $11.54 for all patients, $100.33 for highest risk patients (smokers), and $21.65 for

    The increases in capillary wall permeability and capillary hydrostatic pressure are considered to be the causes for the acute swelling seen in flaps; however, disruption of the circulating flap lymphatics could be another contributory factor. In this study we monitor the development of flap edema in a series of 18 prefabricated flaps and aim to delineate the natural history of this phenomenon by use of lymphography. Postoperative swelling was monitored in a series of 18 pre-expanded prefabricated cervical skin flaps used for hemi-facial burns-scar resurfacing. Time to spontaneous resolution, presence or absence of venous congestion, and clinical outcome were recorded. In two cases, indocyanine-green (ICG) lymphography was used to monitor the dermal backflow pattern until swelling had completely resolved. Average moving velocity of ICG after injection as well as flap thickness was also recorded over the follow-up period. The average moving velocity of ICG in the flap lymphatics improved from 0.48 cm/min to 1.5 cm/min in the first 12 days after flap transfer. The dermal backflow pattern was stardust in the first 12 days, indicating moderate lymphedema, transforming to splash from week three, and a robust collecting lymphatic vessel occurring from the fifth month, indicating mild lymphedema and lymphatic channel recovery, respectively. Transient swelling was observed in all prefabricated flaps in our series. We postulate that this is mostly secondary to lymphatic disruption that subsides as lymphangiogenesis takes place. ICG lymphography is an inexpensive, safe, and easy-to-use imaging technology that could be used in the monitoring of postoperative lymphedema seen in prefabricated flaps.

    Objective: To investigate the effects and related mechanism of bivalirudin on the survival of random skin flap on the back of rat. Methods: Thirty SD rats were divided into bivalirudin group and normal saline group according to the random number table, with 15 rats in each group. The random flap model with size of 9 cm×3 cm was reproduced on the back of rats in two groups. Immediately post injury, rats in bivalirudin group were intraperitoneally injected with 5 mg/mL bivalirudin (0.8 mL/kg), while rats in normal saline group were intraperitoneally injected with normal saline (0.8 mL/kg) once a day. The continuous injection lasted for 7 days. The flap was divided into distal area, middle area and proximal area averagely based on the flap blood supply. On post injury day (PID) 1, 3, and 7, the overall survival of each area of flap was observed with naked eyes. On PID 7, the survival rate of flap was calculated, and then the morphology of skin tissue at the center of the three areas of flap was observed by HE staining, the microvessel density (MVD) of the middle area of flap was calculated, and the expression of vascular endothelial growth factor (VEGF) of the middle area of flap was detected with immunohistochemical staining. Data were processed with t test. Results: (1) On PID 1, flaps of rats in two groups had different degrees of swelling, mainly concentrated in distal area, but there was no obvious necrosis. The middle area and proximal area of flaps in two groups were survived. On PID 3, the necrosis of flaps of rats in two groups was concentrated in the middle area, while the proximal area of flap was still in survival state, and most distal area of flap was necrosis with a little scab. On PID 7, the necrosis of middle area of flaps of rats in two groups was gradually fused, and the survival area of flap of rats in bivalirudin group was larger than that in normal saline group. The distal area of flap was almost necrotic, and the proximal area of flap was

    We reported on the incidence of isolated penile torsion among our healthy children and our approach to this anomaly. Between 2011 and 2014, newborn babies with penile torsion were classified according to the angle of torsion. Surgical correction (penile degloving and reattachment for moderate cases and dorsal dartos flap technique in case of resistance) after 6 months was advised to the babies with rotations more than 45°. Among 1000 newborn babies, 200 isolated penile torsions were found, and among these, 43 had torsions more than 45°, and 4 of these had angles greater than 90°. The mean angle of the rotations was found 30.45° (median: 20°). In total, 8 children with 60° torsions were previously circumcised. Surgery was performed on 19 patients, with a mean patient age of 12 ± 2 months. Of these 19, 13 babies were corrected with degloving and reattachment. This technique was not enough on the remaining 6 patients; therefore, derotational dorsal dartos flap was added to correct the torsion. After a mean of 15.6 ± 9.8 months, residual penile rotation, less than 15°, was found only in 2 children. The incidence of isolated penile torsion is 20% in newborns. However, rotation more than 45° angles are seen in 4.3% of male babies. Correction is not necessary in mild degrees, and penile degloving with reattachment is enough in most cases. If the initial correction is insufficient, dorsal dartos flap rotation is easy and effective. Prior circumcision neither disturbs the operative procedure nor affects the outcomes.

    Skin envelope degloving of fingers are rare injuries that require rapid care and surgical treatment. Mostly caused by ring finger injuries, these traumas include bone, tendon and neurovascular pedicle damage. The authors present an unusual case of finger degloving limited exclusively to the skin envelope, without skeletal, tendinous or vascular lesion. This rare case of skin envelope degloving rendered microsurgical revascularization impossible. The authors report the results at 12 months following salvage reconstruction combining a partial second toe pulp free flap for the volar side and a dermal substitute with a thin skin graft for the dorsum.

    Skin tumours of the anterior auricular concha are not uncommon. Wider excision and immediate reconstruction are required to reduce the risks of recurrence of the disease, cartilage infection and external ear distortion. Many surgical methods have been described for reconstruction of conchal defects. Post-auricular island flaps, such as the revolving-door (RD) flap, and full-thickness skin grafts (FTSGs) are the most-performed procedures. Although the RD flap has been fully described, it is not widely accepted and many surgeons, in their daily practice, prefer to use FTSG. It is a common experience that FTSGs are more subjected to centripetal contraction, decreasing the structural firmness of the conchal cavity and affecting functional and aesthetic outcomes. Furthermore, FTSGs are more prone to delay in wound healing due to the difficult access to this region that hinders adequate tie-over dressings. Between March 2003 and January 2007, 40 patients affected by T1 and T2 non-melanotic skin cancer and T1 melanoma of the anterior conchal surface of the external ear were included in a prospective study and randomly assigned to the RD reconstructed group or to the FTSG reconstructed group to investigate, compare and define advantages and disadvantages of both the techniques. Visual Analogue Scale (VAS) was used to evaluate the overall outcome and the colour and texture match. No flap or skin graft total loss was observed. Six patients (30%) showed partial failure of FTSG. The RD group demonstrated excellent cosmetic outcome, ideal colour match, adequate structure of external ear, projection and shape. Wilcoxon matched-pairs rank-sum test demonstrated statistically significant higher scores for the RD group compared to the FTSG group (p<0.0001). The RD harvesting technique is easy and quicker than the FTSG technique. RD flap should be considered as the first choice for reconstruction of anterior auricular conchal defects following wider excision of skin tumours

    Full Text Available Background: Survival of random-pattern skin flaps is important for the success of plastic and reconstructive surgeries. This study investigates isoflurane-induced protection against ischemia of skin flap and the underlying molecular mechanism in this process. Methods: Human umbilical vein endothelial cells (HUVECs and human skin fibroblast cells were exposed to isoflurane for 4 h. Expression of hypoxia inducible factor-1α (HIF-1α, heme oxygenase-1 (HO-1 and vascular endothelial growth factor (VEGF were analyzed up to 24 h post isoflurane exposure using qRT-PCR and western blot, or ELISA analyses. PI3K inhibitors - LY 294002 and wortmannin, mTOR inhibitor - rapamycin, and GSK3β inhibitor - SB 216763 were used respectively to assess the effects of isoflurane treatment and HIF-1α expression. Furthermore, 40 rats were randomly divided into 5 groups (control, isoflurane, scrambled siRNA plus isoflurane, HIF-1α siRNA plus isoflurane, and DMOG and subjected to random-pattern skin flaps operation. Rats were prepared for evaluation of flap survival and full-feld laser perfusion imager (FLPI (at 7 day and microvessel density evaluation (at 10 day. Results: Isoflurane exposure induced expression of HIF-1α protein, HO-1 and VEGF mRNA and proteins in a time-dependent manner. Both LY 294002 and wortmannin inhibited phospho-Akt, phospho-mTOR, phospho-GSK 3β and HIF-1α expression after isoflurane exposure. Both wortmannin and rapamycin inhibited isoflurane-induced phospho-4E-BP1 (Ser 65 and phospho-P70s6k (Thr 389 and HIF-1α expression. SB 216763 pre-treatment could further enhance isoflurane-induced expression of phospho-GSK 3β (Ser 9 and HIF-1α protein compared to the isoflurane-alone cells. In animal experiments, isoflurane alone, scrambled siRNA plus isoflurane, or DMOG groups had significantly upregulated vascularity and increased survival of the skin flaps compared to the controls. However, HIF-1α knockdown abrogated the protective effect of

    Full Text Available Skin allografts have been used in medical practice for over a century owing to their unique composition as a biological dressing. Skin allografts can be obtained in several preparations such as cryopreserved, glycerol-preserved, and fresh allograft. A glycerol-preserved allograft (GPA was introduced in the early 1980s. It has several advantages compared with other dressings such as ease of processing, storage and transport, lower cost, less antigenicity, antimicrobial properties, and neo-vascularisation promoting properties. Skin allografts are mainly used in the management of severe burn injuries, chronic ulcers, and complex, traumatic wounds. Published reports of the use of skin allografts in association with free flap surgery are few or non existent. We would like to share our experience of several cases of free tissue transfer that utilised GPA as a temporary wound dressing in multiple scenarios. On the basis of this case series, we would like to recommend that a GPA be used as a temporary dressing in conjunction with free flap surgery when required to protect the flap pedicle, allowing time for the edema to subside and the wound can then be closed for a better aesthetic outcome.

    2006-01-01

    Background: Patients with central breast neoplasms account for 5 to 20% of breast cancer cases and, for a long time, they have been denied Breast Conservation Surgery (BCS) and conventionally treated with mastectomy. The high incidence of Nipple-Areola-Complex (NAC) involvement usually associated with these tumors necessitates nipple and areolar resection together with an adequate safety margin around the tumor, which yields an unacceptable cosmetic result. With the help of Oncoplastic Surgical Techniques, BCS can be offered to these patients. In this study central quadrantectomy and breast reconstruction by an infero-Iaterally based pedicled flap were evaluated. Patients and Methods: This study comprised 23 women with central breast tumors treated at the National Cancer Institute (NC]), Cairo University and at the Aswan Cancer Center, Egyptian Ministry of Health. Their ages ranged from 31 to 62 years (mean: 48.4±10.2 years). Twenty-two had a palpable mass, while only I had Paget's disease of the nipple without mass. The size of their tumors ranged from 4 to 33mm (mean: 16.9±8.6mm). Only 9 women showed clinical suspicion of NAC involvement in the form of nipple retraction. Seventeen cases had their tumors strictly in the retro-areolar region, while 5 had tumors extending for a maximum of I.5Cm beyond the areolar edge. All patients underwent central quadrantec-tomy with NAC resection removing a cylinder of breast tissue reaching down to the pectoral muscle together with axillary dissection. Advancement of an infero-Iaterally based skin-glandular flap was then carried out. All patients received adjuvant radiotherapy with or without chemotherapy or hormonal therapy. Results: Fourteen patients showed pathological evidence of nipple infiltration (60.8%). The free safety margin (SM) ranged from 9 to 13mm (mean: 10. 0.9mm). This could be accomplished from the first attempt in 18 patients; however, in 5 patients a second wider excision was needed to obtain an adequate

    Full Text Available La reconstrucción del pene sigue siendo uno de los mayores retos de la Cirugía Plástica debido a la complejidad inherente que conlleva el conseguir tanto la forma anatómica como la función urológica del pene. El objetivo ideal del cirujano al realizar una faloplastia incluye la construcción, en una sola etapa, de un pene estéticamente aceptable y con sensibilidad erógena y táctil, que permita al paciente orinar de pie y mantener relaciones sexuales. La multitud existente de colgajos que pueden ser utilizados para la reconstrucción del pene sólo demuestra que ninguna de estas técnicas se considera ideal. Sin embargo, el colgajo radial es el que se utiliza más frecuentemente y es considerado universalmente como la técnica estándar. Las desventajas relativas de la misma son el número más elevado de fístulas que aparecen inicialmente, la cicatriz residual en el antebrazo y las complicaciones urológicas potenciales a largo plazo. Presentamos una reconstrucción de pene realizada mediante un colgajo libre radial antebraquial con un nuevo diseño geométrico bidimensional que permite la creación tridimensional de un neofalo con excelentes resultados estéticos.Reconstruction of penile defects remains one of the greatest challenges in Plastic Surgery because of the inherent complexity of restoring both the anatomical form and the urologic function of the penis.

The multitude of flaps used for phalloplasty only demonstrates that none of these techniques is considered ideal. Still, the radial forearm flap is the most frequently used one and universally considered as the standard technique. The relative disadvantages of this technique are the rather high number of initial fistulas, the residual

    Closure of the donor site on the index finger after raising a first dorsal metacarpal artery (DMA) flap harvest is challenging. The conventional choice is to use a full-thickness skin graft. However, this procedure is associated with several complications and a second donor site to harvest the skin graft is inevitable. The aim of this study was to design a modified incision to allow harvest of a first DMA flap without skin graft. From 2015 to 2016, 18 patients with a soft tissue defect of the thumb had reconstruction of the defect using a first DMA flap. A modified incision was used and a relaying perforator flap pedicled on the second DMA was raised through the same incision to cover the donor site. Patient satisfaction, appearance of the injured hand, and the active range of motion (ROM) were assessed. The sensitivity was evaluated by the 2-point discrimination (2-PD) test. All flaps survived completely without complications. Good coverage was obtained with only one linear scar in the dorsum of the hand and no skin grafts. All patients recovered full range of movement in their fingers and regained sensitivity of the flaps. All patients were satisfied with their hand function according to the Michigan Hand Outcomes Questionnaire (MHQ). The mean cosmetic score for the appearance of the injured hand was 8.2 out of 10. Using our modified incision, it was possible to harvest a second DMA flap at the same time as a first DMA flap allowing simultaneous coverage of the donor defect on the index finger. This prevented the need for a skin graft with all of the associated disadvantages. Copyright © 2018. Published by Elsevier Ltd.

    Skin flap grafting is a form of transplantation widely used in plastic surgery. However, ischemia/reperfusion injury is the main factor which reduces the survival rate of flaps following grafting. We investigated whether photobiomodulation (PBM) precondition prior to human adipose-derived stromal cell (hASC) spheroid (PBM-spheroid) transplantation improved skin tissue functional recovery by the stimulation of angiogenesis and tissue regeneration in skin flap of mice. The LED had an emission wavelength peaked at 660 ± 20 nm (6 J/cm 2 , 10 mW/cm 2 ). The expression of angiogenic growth factors in PBM-spheroid hASCs was much greater than that of not-PBM-treated spheroid or monolayer-cultured hASCs. From immunochemical staining analysis, the hASCs of PBM-spheroid were CD31 + , KDR + , and CD34 + , whereas monolayer-cultured hASCs were negative for these markers. To evaluate the therapeutic effect of hASC PBM-spheroid in vivo, PBS, monolayer-cultured hASCs, and not-PBM-spheroid were transplanted into a skin flap model. The animals were observed for 14 days. The PBM-spheroid hASCs transplanted into the skin flap ischemia differentiated into endothelial cells and remained differentiated. Transplantation of PBM-spheroid hASCs into the skin flap ischemia significantly elevated the density of vascular formations through angiogenic factors released by the skin flap ischemia and enhanced tissue regeneration at the lesion site. Consistent with these results, the transplantation of PBM-spheroid hASCs significantly improved functional recovery compared with PBS, monolayer-cultured hASCs, and not-PBM-spheroid treatment. These findings suggest that transplantation of PBM-spheroid hASCs may be an effective stem cell therapy for the treatment of skin flap ischemia.

    The repair of extensive upper limb skin lesions in pediatric patients is extremely challenging due to substantial limitations of flap size and donor-site morbidity. We aimed to create an oversize preexpanded flap based on intercostal artery perforators for large-scale resurfacing of the upper extremity in children. Between March 2013 and August 2016, 11 patients underwent reconstructive treatment for extensive skin lesions in the upper extremity using a preexpanded intercostal artery perforator flap. Preoperatively, 2 to 4 candidate perforators were selected as potential pedicle vessels based on duplex ultrasound examination. After tissue expander implantation in the thoracodorsal area, regular saline injections were performed until the expanded flap was sufficient in size. Then, a pedicled flap was formed to resurface the skin lesion of the upper limb. The pedicles were transected 3 weeks after flap transfer. Flap survival, complications, and long-term outcome were evaluated. The average time of tissue expansion was 133 days with a mean final volume of 1713 mL. The thoracoabdominal flaps were based on 2 to 6 pedicles and used to resurface a mean skin defect area of 238 cm ranging from 180 to 357 cm. In all cases, primary donor-site closure was achieved. Marginal necrosis was seen in 5 cases. The reconstructed limbs showed satisfactory outcome in both aesthetic and functional aspects. The preexpanded intercostal artery perforator flap enables 1-block repair of extensive upper limb skin lesions. Due to limited donor-site morbidity and a pedicled technique, this resurfacing approach represents a useful tool especially in pediatric patients.

    Phospholipid-based nanocarriers are attractive drug carriers for improved local skin therapy. In the present study, the recently developed isolated perfused human skin flap (IPHSF) model was used to directly compare the skin penetration enhancing potential of the three commonly used nanocarriers, namely conventional liposomes (CLs), deformable liposomes (DLs) and solid lipid nanoparticles (SLNs). Two fluorescent markers, calcein (hydrophilic) or rhodamine (lipophilic), were incorporated individually in the three nanosystems. The nanocarrier size ranged between 200 and 300nm; the surface charge and entrapment efficiency for both markers were dependent on the lipid composition and the employed surfactant. Both carrier-associated markers could not penetrate the full thickness human skin, confirming their suitability for dermal drug delivery. CLs exhibited higher retention of both markers on the skin surface compared to DLs and SLNs, indicating a depo formation. DLs and SLNs enabled the deeper penetration of the two markers into the skin layers. In vitro and ex vivo skin penetration studies performed on the cellophane membrane and full thickness pig/human skin, respectively, confirmed the findings. In conclusion, efficient dermal drug delivery can be achieved by optimization of a lipid nanocarrier on the suitable skin-mimicking model to assure system's accumulation in the targeted skin layer.

    Objective To observe effects of meshed relaxing short incisions on the level of superoxide dismutase and malondialdehyde in rat tension skin flap, and to investigate the mechanism of meshed relaxing short incisions (MRSI) on wound healing process of tension skin flap. Method An experimental model was designed to investingate the changes of superoxide dismutase (SOD) and malondialdehyde (MDA) in rat skin flap tissue each period of wound healing (12h, 24h, 48h, 72h after suture). In the meantime, the biochemical reaction were employed. Results Our results showed that SOD content in rat skin flap tissue from MRSI group were significant higher than that of hypertension group (P≤ 0.05), while MDA content was significantly lower (P≤ 0.05). Conclusion The decrease of MDA contents may be one of the causes that MRSI improves microcirculation of skin flap, and reduces edema and facilitates healing of skin flap.

    A histological evaluation of peeling-induced skin changes in subcutaneous undermined preauricular facial skin flaps of nine patients was performed. There were three treatment groups: Trichloroacetic acid (TCA) 25%, TCA 40% and phenol/croton oil; one group served as control. Two independent evaluators determined the epidermal and dermal thickness and the depth of necrosis (micrometre). The percentual tissue damage due to the peeling was calculated, and a one-sample t-test for statistical significance was performed. On the basis of the histomorphological changes, peeling depth was classified as superficial, superficial-partial, deep-partial and full thickness chemical burn. The histological results revealed a progression of wound depth for different peeling agents without full thickness necrosis. TCA peels of up to 40% can be safely applied on subcutaneous undermined facial skin flaps without impairing the vascular patency, producing a predictable chemical burn, whereas deep peels such as phenol/croton oil peels should not be applied on subcutaneous undermined skin so as to not produce skin slough or necrosis by impairing vascular patency.

    The purpose of this study was to develop and validate a multimedia software application for mobile platforms to assist in the teaching and learning process of design and construction of a skin flap. Traditional training in surgery is based on learning by doing. Initially, the use of cadavers and animal models appeared to be a valid alternative for training. However, many conflicts with these training models prompted progression to synthetic and virtual reality models. Fifty volunteer fifth- and sixth-year medical students completed a pretest and were randomly allocated into two groups of 25 students each. The control group was exposed for 5 minutes to a standard text-based print article, while the test group used multimedia software describing how to fashion a rhomboid flap. Each group then performed a cutaneous flap on a training bench model while being evaluated by three blinded BSPS (Brazilian Society of Plastic Surgery) board-certified surgeons using the OSATS (Objective Structured Assessment of Technical Skill) protocol and answered a post-test. The text-based group was then tested again using the software. The computer-assisted learning (CAL) group had superior performance as confirmed by checklist scores (pmultimedia method as the best study tool. CAL learners exhibited better subjective and objective performance when fashioning rhomboid flaps as compared to those taught with standard print material. These findings indicate that students preferred to learn using the multimedia method.

    2010-06-29

    Knowledge of penile embryology and anatomy is essential to any pediatric urologist in order to fully understand and treat congenital anomalies. Sex differentiation of the external genitalia occurs between the 7th and 17th weeks of gestation. The Y chromosome initiates male differentiation through the SRY gene, which triggers testicular development. Under the influence of androgens produced by the testes, external genitalia then develop into the penis and scrotum. Dorsal nerves supply penile skin sensation and lie within Buck's fascia. These nerves are notably absent at the 12 o'clock position. Perineal nerves supply skin sensation to the ventral shaft skin and frenulum. Cavernosal nerves lie within the corpora cavernosa and are responsible for sexual function. Paired cavernosal, dorsal, and bulbourethral arteries have extensive anastomotic connections. During erection, the cavernosal artery causes engorgement of the cavernosa, while the deep dorsal artery leads to glans enlargement. The majority of venous drainage occurs through a single, deep dorsal vein into which multiple emissary veins from the corpora and circumflex veins from the spongiosum drain. The corpora cavernosa and spongiosum are all made of spongy erectile tissue. Buck's fascia circumferentially envelops all three structures, splitting into two leaves ventrally at the spongiosum. The male urethra is composed of six parts: bladder neck, prostatic, membranous, bulbous, penile, and fossa navicularis. The urethra receives its blood supply from both proximal and distal directions.

    Full Text Available Knowledge of penile embryology and anatomy is essential to any pediatric urologist in order to fully understand and treat congenital anomalies. Sex differentiation of the external genitalia occurs between the 7thand 17th weeks of gestation. The Y chromosome initiates male differentiation through the SRY gene, which triggers testicular development. Under the influence of androgens produced by the testes, external genitalia then develop into the penis and scrotum. Dorsal nerves supply penile skin sensation and lie within Buck's fascia. These nerves are notably absent at the 12 o'clock position. Perineal nerves supply skin sensation to the ventral shaft skin and frenulum. Cavernosal nerves lie within the corpora cavernosa and are responsible for sexual function. Paired cavernosal, dorsal, and bulbourethral arteries have extensive anastomotic connections. During erection, the cavernosal artery causes engorgement of the cavernosa, while the deep dorsal artery leads to glans enlargement. The majority of venous drainage occurs through a single, deep dorsal vein into which multiple emissary veins from the corpora and circumflex veins from the spongiosum drain. The corpora cavernosa and spongiosum are all made of spongy erectile tissue. Buck's fascia circumferentially envelops all three structures, splitting into two leaves ventrally at the spongiosum.

    It is still difficult to prevent partial or full-thickness flap necrosis. In this study, the effects of a cream containing menthol and methyl salicylate on the viability of randompattern skin flaps were studied. Forty female Sprague-Dawley rats were divided into two equal groups. Caudally based dorsal random-pattern skin flaps were elevated, including the panniculus carnosus. In the study group, 1.5 mL of a cream containing menthol and methyl salicylate was applied to the skin of the flap, and saline solution (0.9%) was used in the control group. Upon completion of the experiment, flap necrosis was analyzed with imaging software and radionuclide scintigraphy. Histopathological measurements were made of the percentage of viable flaps, the number of vessels, and the width of the panniculus carnosus muscle. According to the photographic analysis, the mean viable flap surface area in the study group was larger than that in the control group (P=0.004). According to the scintigrams, no change in radioactivity uptake was seen in the study group (P>0.05). However, a significant decrease was observed in the control group (P=0.006). No statistically significant differences were observed between the groups in terms of the percentage of viable flaps, the number of vessels, or the width of the panniculus carnosus muscle (P>0.05). Based on these results, it is certain that the cream did not reduce the viability of the flaps. Due to its vasodilatory effect, it can be used as a component of the dressing in reconstructive operations where skin perfusion is compromised.

    Airway replacement after long-segment tracheal resection for benign and malignant disease remains a challenging problem because of the lack of a substitute conduit. Ideally, an airway substitute should be well vascularized, rigid, and autologous to avoid infections, airway stenosis, and the need for immunosuppression. We report the development of an autologous tracheal substitute for long-segment tracheal resection that satisfies these criteria and demonstrates excellent short-term functional results in a large-animal study. Twelve adult pigs underwent long-segment (6 cm, 60% of total length) tracheal resection. Autologous costal cartilage strips measuring 6 cm x 2 mm were harvested from the chest wall and inserted at regular 0.5-cm intervals between dermal layers of a cervical skin flap. The neotrachea was then scaffolded by rotating the composite cartilage skin flap around a silicone stent measuring 6 cm in length and 1.4 cm in diameter. The neotrachea replaced the long segment of tracheal resection, and the donor flap site was closed with a double-Z plasty. Animals were killed at 1 week (group I, n = 4), 2 weeks (group II, n = 4), and 5 weeks (group III, n = 4). In group III the stent was removed 1 week before death. Viability of the neotrachea was monitored by means of daily flexible bronchoscopy and histologic examination at autopsy. Long-term morbidity and mortality were determined by monitoring weight gain, respiratory distress, and survival. There was no mortality during the study period. Weight gain was appropriate in all animals. Daily bronchoscopy and postmortem histologic evaluation confirmed excellent viability of the neotrachea. There was no evidence of suture-line dehiscence. Five animals had distal granulomas that were removed by using rigid bronchoscopy. In group III 1 animal had tracheomalacia, which was successfully managed by means of insertion of a silicon stent.

    Until recently, no single, universally accepted surgical method has existed for all types of concealed penis repairs. We describe a new surgical technique for repairing concealed penis by using an advanced musculocutaneous scrotal flap. From January 2010 to June 2014, we evaluated 12 patients (12-40 years old) with concealed penises who were surgically treated with an advanced musculocutaneous scrotal flap technique after degloving through a ventral approach. All the patients were scheduled for regular follow-up at 6, 12, and 24 weeks postoperatively. The satisfaction grade for penile size, morphology, and voiding status were evaluated using a questionnaire preoperatively and at all of the follow-ups. Information regarding complications was obtained during the postoperative hospital stay and at all follow-ups. The patients' satisfaction grades, which included the penile size, morphology, and voiding status, improved postoperatively compared to those preoperatively. All patients had penile lymphedema postoperatively; however, this disappeared within 6 weeks. There were no complications such as skin necrosis and contracture, voiding difficulty, or erectile dysfunction. Our advanced musculocutaneous scrotal flap technique for concealed penis repair is technically easy and safe. In addition, it provides a good cosmetic appearance, functional outcomes and excellent postoperative satisfaction grades. Lastly, it seems applicable in any type of concealed penis, including cases in which the ventral skin defect is difficult to cover.

    Surgical delay is an invasive method requiring a two-stage surgical procedure. Hence, methods that may serve as an alternative to surgical delay have become the focus of interest of research studies. From a conceptual view, any technique that interrupts the blood flow along the edges of a proposed flap will render the flap ischemic and induce a delay phenomenon. Polidocanol (Aethoxysklerol(®)-Kreussler) was initially used as a local anesthetic. Nowadays, it has been used as a sclerosing agent to treat telangiectasias and varicose veins. The aim of this experimental study was to investigate the effects of polidocanol injected around the periphery of a random flap as a sclerosing agent on flap delay and survival in a random flap model. A preliminary histopathologic study was performed on two rats to evaluate the sclerosing effect and distribution of polidocanol injection. After the preliminary study, the main study was carried out with three groups: group 1: dorsal flap (n = 10); group 2: dorsal flap + surgical delay (n = 10), group 3: dorsal flap + chemical delay (n = 10). Tissue samples obtained from the flap and injection area revealed destruction of intradermal vessels. The area affected with sclerosis was limited to 0.1 cm beyond the injection site. Mean viable flap areas were 52.1 ± 4.38% (44.0-58.2) in group 1, 64.8 ± 8.92% (57.2-89.2) in group 2, and 71.8 ± 5.18% (64.0-84.0) in group 3. A statistically highly significant difference was found between the surgical delay and chemical delay groups versus the group without delay (p injection around the dorsal flap in the rat is a safe and easy method for nonsurgical delay. The results have shown a flap survival benefit that is superior to controls and equivalent to surgical delay. The clinical application of polidocanol, already in clinical practice for occlusal of telangiectasias, for surgical delay appears feasible.

    The radial forearm flap transfer has proved to be the standard technique in penile reconstruction. However, this operation still leads to a residual scar on the forearm. In the reconstruction of partial penis necrosis, achieving a desirable appearance and functional recovery while minimizing donor-site damage remains an unsolved problem. In this study, we report our experience using penile elongation combined with glanuloplasty to rebuild the partially necrotic penis.A retrospective review of a consecutive series of 33 patients with partial penis necrosis after microwave thermotherapy (not from our hospital) from December 2008 to May 2012 was conducted at the Department of Plastic and Reconstructive Surgery, Shanghai 9th People's Hospital. These patients, with an age range from 20 to 36 years, first underwent a scrotal skin flap transfer to cover residual cavernosum. The penis was simultaneously elongated at the proximal end. Six months later, all patients received glanuloplasty using expanded polytetrafluoroethylene that was implanted at the distal end of transferred scrotal skin flap to create the neoglans.Anthropometric measurements of preoperative and postoperative penile length were performed with an average follow-up period of 28 months. The mean extended penile length average was 2.57 cm, ranging from 3.16 to 5.73 cm. Patients' satisfaction rate was 88%. In addition, preoperative and postoperative photographs were reviewed for objective and subjective assessment of outcome parameters such as appearance of neophallus, urination, and erogenous sensation. Most importantly, the rebuilt penis postoperatively showed almost normal shape and restoration of basic physiologic function in most of the patients, with an acceptable complication rate. These preliminary results may provide a useful strategy for the reconstruction of a partially necrotic penis using a novel, simple, and effective approach.

    To investigate the feasibility and therapeutic effect of free posterior interrosseous artery flap in a bridge fashion for combined skin and bilateral artery defects at palmar side of fingers. 6 cases with combined skin and bilateral artery defects at palmar side of fingers were treated with long-pedicled free posterior interrosseous artery flap in a bridge fashion. The flap size ranged from 3.5 cm x 2.0 cm to 6.5 em x 3.0 cm. The wounds at donor sites were closed directly. All the 6 flaps survived completely without any complication, and the wounds healed primarily. The blood supply and vein drainage in all the 6 fingers were normal. 4 cases were followed up for 1-12 months (average, 7 months). Satisfactory cosmetic and functional results were achieved. The flaps looked a little bit thicker than the surrounding tissue. The long-pedicled free posterior interrosseous artery flap in a bridge fashion is a good option for reconstruction of the combined skin and bilateral artery defects at palmar side of fingers in one stage.

    Full Text Available Introduction Penile fracture is a urological emergency caused by direct trauma to an erected penis, tearing the tunica albuginea in the corpus cavernosum. The preferred treatment method is draining the hematoma and surgical repair of tunica albuginea tear as soon as possible following diagnosis. Materials and Methods Forty-nine patients who were diagnosed with penile fracture between January 2009 and December 2014 were reviewed. Physical examination was performed to see the extent of penile hematoma, the side of the penile curvature and the presence of blood in the external meatus. Two patients who were diagnosed with urethrorrhagia underwent retrograde urethrogram for urethral injury. In all patients, penile skin was peeled using a circular subcoronal degloving incision and tunica tear was repaired using absorbable suture materials. The patients were then followed for painful erections, penile deformities and erection angles. Results The average age of the 49 patients, who were included in the study, was 36.5 years (21-65. In their etiological questioning, most patients reported the fracture occurring during sexual intercourse. Retrograde urethrography was indicated in 2 patients with blood in the external meatus and were diagnosed with urethral injury. The patients were taken to emergency surgery. Tunica defects varied between 1 and 2 cm. Incomplete urethral injuries were primarily repaired around 18 French Foley catheter. None of the patients reported penile deformity or painful erections. Their erection angles were found to be within the normal range. Conclusion Even though it is a relatively rare condition, penile fractures are so important that might cause serious complications when not treated surgically. A thorough anamnesis and physical examination suffice for diagnosis.

    Full Text Available The purpose of this study was to develop and validate a multimedia software application for mobile platforms to assist in the teaching and learning process of design and construction of a skin flap. Traditional training in surgery is based on learning by doing. Initially, the use of cadavers and animal models appeared to be a valid alternative for training. However, many conflicts with these training models prompted progression to synthetic and virtual reality models. Fifty volunteer fifth- and sixth-year medical students completed a pretest and were randomly allocated into two groups of 25 students each. The control group was exposed for 5 minutes to a standard text-based print article, while the test group used multimedia software describing how to fashion a rhomboid flap. Each group then performed a cutaneous flap on a training bench model while being evaluated by three blinded BSPS (Brazilian Society of Plastic Surgery board-certified surgeons using the OSATS (Objective Structured Assessment of Technical Skill protocol and answered a post-test. The text-based group was then tested again using the software. The computer-assisted learning (CAL group had superior performance as confirmed by checklist scores (p<0.002, overall global assessment (p = 0.017 and post-test results (p<0.001. All participants ranked the multimedia method as the best study tool. CAL learners exhibited better subjective and objective performance when fashioning rhomboid flaps as compared to those taught with standard print material. These findings indicate that students preferred to learn using the multimedia method.

    Purpose: This case study was designated to confirm the optimized plan was used to treat skin surface of left leg in three stages. 1. To evaluate dose distribution and plan quality by alternating of the source loading catheters pattern in flexible Freiberg Flap skin surface (FFSS) applicator. 2. To investigate any impact on Dose Volume Histogram (DVH) of large superficial surface target volume coverage. 3. To compare the dose distribution if it was treated with electron beam. Methods: The Freiburg Flap is a flexible mesh style surface mold for skin radiation or intraoperative surface treatments. The Freiburg Flap consists of multiple spheres that are attached to each other, holding and guiding up to 18 treatment catheters. The Freiburg Flap also ensures a constant distance of 5mm from the treatment catheter to the surface. Three treatment trials with individual planning optimization were employed: 18 channels, 9 channels of FF and 6 MeV electron beam. The comparisons were highlighted in target coverage, dose conformity and dose sparing of surrounding tissues. Results: The first 18 channels brachytherapy plan was generated with 18 catheters inside the skin-wrapped up flap (Figure 1A). A second 9 catheters plan was generated associated with the same calculation points which were assigned to match prescription for target coverage as 18 catheters plan (Figure 1B). The optimized inverse plan was employed to reduce the dose to adjacent structures such as tibia or fibula. The comparison of DVH’s was depicted on Figure 2. External beam of electron RT plan was depicted in Figure 3. Overcall comparisons among these three were illustrated in Conclusion: The 9-channel Freiburg flap flexible skin applicator offers a reasonably acceptable plan without compromising the coverage. Electron beam was discouraged to use to treat curved skin surface because of low target coverage and high dose in adjacent tissues.

    Botulinum toxin (BTX) A and B are commonly used for aesthetic indications and in neuromuscular disorders. New concepts seek to prove efficacy of BTX for critical tissue perfusion. Our aim was to evaluate BTX A and B in a mouse model of critical flap ischemia for preoperative and intraoperative application. BTX A and B were applied on the vascular pedicle of an axial pattern flap in mice preoperatively or intraoperatively. Blood flow, tissue oxygenation, tissue metabolism, flap necrosis rate, apoptosis assay, and RhoA and eNOS expression were endpoints. Blood-flow measurements 1 d after the flap operation revealed a significant reduction to 53% in the control group, while flow was maintained or increased in all BTX groups (103%-129%). Over 5 d all BTX groups showed significant increase in blood flow to 166-187% (P < 0.01). Microdialysis revealed an increase of glucose and reduced lactate/pyruvate ratio and glycerol levels in the flap tissue of all BTX groups. This resulted in significantly improved tissue survival in all BTX groups compared with the control group (62% ± 10%; all P < 0.01): BTX A preconditioning (84% ± 5%), BTX A application intraoperatively (88% ± 4%), BTX B preconditioning (91% ± 4%), and intraoperative BTX B treatment (92% ± 5%). This was confirmed by TUNEL assay. Immunofluorescence demonstrated RhoA and eNOS expression in BTX groups. All BTX applications were similarly effective, despite pharmacologic dissimilarities and different timing. In conclusion, we were able to show on a vascular, tissue, cell, and molecular level that BTX injection to the feeding arteries supports flap survival through ameliorated blood flow and oxygen delivery.

    To review and present the results of a one-step method employing a free tarsal plate graft and a myocutaneous pedicle flap plus a free skin graft for reconstruction of large upper eyelid defects after tumour surgery. This was a retrospective case-series of 8 patients who underwent reconstruction of the upper eyelid after tumour removal. The horizontal defect involved 50-75% of the lid (3 pts.), more than 75% (3 pts.), and more than 75% plus the lateral canthus (2 pts.). The posterior lamella was reconstructed with contralateral upper eyelid tarsal plate. The anterior lamella was reconstructed with a laterally based myocutaneous pedicle flap in 7 patients, leaving a raw surface under the brow which was covered with a free skin graft. In 1 patient with little skin left under the brow, the anterior lamella was reconstructed with a bi-pedicle orbicularis muscle flap together with a free skin graft. All patients healed without necrosis, did not suffer from lagophthalmos, achieved reasonable cosmesis, and did not need lubricants. In one patient, a contact lens was necessary for three weeks because of corneal erosion. One patient still needs a contact lens 3 months after excision to avoid eye discomfort. Large upper eyelid defects can be reconstructed with a free tarsal plate graft and a laterally based myocutaneous pedicle flap in combination with a free skin graft. Two-step procedures can probably be avoided in most cases.

    Recently, one of the rare sugars, D-allose, has received attention from many researchers because of its availability for mass production and its various physiological functions. Among these, an antioxidative effect has been strongly suggested. In this study, we investigated whether this effect is also applicable to the field of skin surgery. In ischemia-reperfusion injury model using the rat abdominal skin island flap (male Wistar rats, n = 110), D-allose was injected intravenously 15 min before 8-h ischemia. The survival area (%) was measured by digital photographic assessment 1 wk after surgery, and multiple comparisons (Fisher's protected least significant difference) were carried out. Histopathological examination (neutrophilic infiltration into dermis in hematoxylin and eosin stain) and immunostaining (of ectodermal dysplasia-1 (ED1)-positive cells/flap) were assessed. Myeloperoxidase (MPO) activity in the skin flap (sampling at the time of 8 h after reperfusion) was measured spectrophotometrically, and Student t-test was performed. D-allose extended the survival of the remaining flaps, and a dose greater than 30 mg (0.1 mg/g) was necessary to be effective. The flap survival rates in the 30, 60, and 150 mg groups were significantly higher than that in the control (saline) group: 75.87 ± 5.90, 79.27 ± 7.81, and 77.87 ± 6.20 versus 50.53 ± 9.66, respectively (P rare sugars are safer for our bodies as well as the environment; therefore, this rare sugar project is expected to lead to the development of a safer antioxidant for skin flap surgery.

    Described in this study is a surgical concept that supports the "consider and use a pedicled perforator flap whenever possible and indicated" approach to reconstruct a particular skin defect. The operation is entirely free-style; the only principle is to obtain a pedicled perforator flap...... to reconstruct the defect. The perforators are marked with a hand-held Doppler probe and multiple flaps are designed. The appropriate flap is elevated after identifying the perforator(s). Dissection of the perforator(s) or complete incision of the flap margins are not mandatory if the flap is mobilized...... adequately to cover the defect.

    Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years. Proper evaluation of both the primary lesion and lymph nodes is critical, because nodal involvement is the most important factor of survival. The NCCN Clinical Practice Guidelines in Oncology for Penile Cancer provide recommendations on the diagnosis and management of this devastating disease based on evidence and expert consensus.

    Traditional donor-site closure has been associated with serious esthetic and functional morbidity. The purpose of this study was to assess morbidity in esthetics and function and measure the postoperative complications of the radial forearm free flap (RFFF) donor site after using combined local triangular full-thickness skin grafting. This prospective study of patients who underwent reconstruction of head and neck defects using an RFFF was conducted from July 2008 through December 2014. The donor site was repaired with a combined local triangular full-thickness skin graft. Quality of the scar, color match, tendon exposure, presence of necrosis, dehiscence of the suture, and presence of dysesthesia were recorded and analyzed using SPSS 21.0 software. One hundred consecutive patients (71 male and 29 female) underwent RFFF harvesting. RFFF donor-site defects ranged from 15 to 70 cm2; partial skin graft loss occurred in 7% of patients. Five patients (5%) had small dehiscences of the forearm skin graft, and 2 cases (2%) presented tendon exposure. In all cases, these sites healed secondarily by conservative management, with no final impairment of function. Esthetic results were considered excellent in 87%, good in 11%, and suboptimal in 2% of the cases. The combined local triangular full-thickness skin graft is a reliable method for closing RFFF donor-site defects because it obviates a second surgical site, it provides excellent color match and pliability, and it can be used for covering large defects of the donor site.

    The authors describe a case of 33 year old Caucasian married man with an irregular 6 cm penile mass associated with multiple penile ulcers. He reluctantly admitted that 10 years ago he had multiple mineral oil (Vaseline) self injections into the penis, for penile enlargement purposes. The patient had a surgical intervention 10 years ago, but he has recurrent ulcers on his penis. We have administered an intravenous antibiotic therapy combined with local therapy. The term paraffinoma describes a distinct histopathological finding that results from the injection of foreign oily substances into the skin. Although such procedure may be considered rare, they are still performed in some countries. The major point we want emphasis is following: a lot of people seek penile augmentations, it is necessary to remind physicians and the public that nonscientific and inadequate procedure such as Vaseline may lead to debilitating and destructive consequences (Tab. 1, Ref. 12).

    Aesthetic surgery to improve the appearance of the penis, scrotum, and pubic region has successfully evolved. Penile lengthening is performed by releasing the suspensory ligament of the penis followed by use of penile weights. Girth is increased by wrapping a dermal-fat graft around the penile circumference. The choice of surgery is determined by the patient's anatomy and desires.

    Iglesias, Martin; Gonzalez-Chapa, Diego R

    2013-08-01

    Some authors have mentioned that the endoscopic harvesting of the latissimus dorsi muscle flap for breast reconstruction is an uncommon technique that has been abandoned due to its technical complexity. Therefore, its use for immediate breast reconstruction after skin-sparing total mastectomies is reported for only a few patients, without clinical images of the reconstructed breast or of the donor site. This report describes 14 breast reconstructions using the aforementioned approach, with the latissimus dorsi muscle flap harvested by endoscopy plus the insertion of a breast implant in a single surgical procedure. The objective is to show images of the long-range clinical aesthetic results, both in the reconstructed breast and at the donor site as well as the complications so the reader can evaluate the advantages and disadvantages of the technique. From 2008 to 2011, 12 women who experienced skin-sparing total mastectomy and 2 women who underwent modified radical mastectomy were reconstructed using the aforementioned technique. The average age was 42 years (range 30-58 years), and the average body mass index was 29 kg/m(2) (range 22-34 kg/m(2)). Three patients were heavy smokers: one had undergone a previous abdominoplasty; one had hepatitis C; and one had undergone massive weight loss. Immediate reconstructions were performed for 11 patients, and 3 reconstructions were delayed. The implant volume ranged from 355 to 640 ml. The average endoscopic harvesting time was 163.5 min (range 120-240 min), and the average bleeding was 300 ml. Four patients experienced seromas at the donor site. Acceptance of the reconstructed breast was good in six cases, moderate in seven cases, and poor in one case. Acceptance of the donor site was good in 13 cases and moderate for 1 case. Endoscopic harvesting of the latissimus dorsi muscle has technical difficulties that have limited its acceptance. However, this technique offers the same quality of breast reconstruction as the

    Full Text Available PURPOSE: To evaluate the effects of capsaicin on the viability of ischemic random-pattern skin flaps in rats. METHODS:Forty EPM1-Wistar rats were randomized into two groups of 20 animals each, the capsaicin group and the control group. A random-pattern skin flap measuring 10 x 4cm was raised and a plastic barrier was placed between the flap and the donor site. After the surgical procedure, the control group was treated with an inert vehicle in the form of a cream applied uniformly to a rayon bandage which, in turn, was applied to the surface of the skin flap. The capsaicin group was treated in the same way, but in this case capsaicin was added to the cream. This procedure was repeated for two consecutive days. RESULTS: There was a significantly smaller amount of flap necrosis in the capsaicin group (35.07% than in the control group (44.75% (p=0.035. CONCLUSION:Topical administration of capsaicin improved the viability of ischemic random-pattern skin flaps in rats.OBJETIVO: Avaliar os efeitos da capsaicina na viabilidade de retalhos isquêmicos randômicos em ratos.

Full thickness soft tissue defects, up to 12 cm in length and up to 8 cm in width. Sufficient vascularization of the foot required, in osteomyelitis, and when joints, fractures, implants and tendons are exposed and when a split skin graft, a local flap, a suralis perforator flap or a free flap is not indicated. For patients, in whom a 1-2 h operation is not possible; necessity of angioplasty; decollement or scars around the distal perforators of the posterior tibial artery; local infection or necrosis of soft tissues and/or bone, which cannot be totally excised. Radical debridement; flap dissection without tourniquet; microdissection; design of the flap on the skin: pivot point ~ 10 cm (6-14 cm) proximal of the tip of the medial malleolus; base ~ 5 cm in width, between the course of the saphenous nerve and of the great saphenous vein and the Achilles tendon; adipofascial pedicle up to 15 cm in length sited over the septum between soleus and flexor digitorum muscles, following the course of the saphenous nerve, with a central skin stripe, which expands into a proximal skin island; skin island is outlined similar to the defect, but larger by 1 to 2 cm, surrounded by an adipofascial border: adjustment of the planning as well as of the elevation of these flaps according to the individual position and the caliber of perforators requires in each case the search for a perforator at the estimated pivot point. Delay of transposition, if the division of more than one perforator proximal to the pivot point obviously diminishes circulation. No "tunnelling "of the pedicle; defects of skin due to the elevation of the flap are replaced by split and meshed skin grafts or temporary

    To investigate the surgical outcomes of dorsal onlay urethroplasty (DOU) using buccal mucosa graft (BMG) or penile skin graft (PSG) and to assess the effect of stricture length in men with anterior urethral strictures. A prospective cohort included men with anterior urethral strictures between 2008 and 2015. Patients underwent DOU using PSG or BMG. Patients had urethrography and uroflowmetry at 0, 3, 6, 12 months, and urethroscopy when needed. Student's t test, Mann-Whitney U tests, and Pearson's Chi-square test were used for analysis. Sixty-nine patients (43 ± 14 year) were included, 31 received BMG, and 38 received PSG. Mean stricture length was 8 ± 3 cm, mean operative time was 145 ± 31 min, and mean follow-up was 56 ± 10 mo. Success rate was 87 % (90 % BMG vs. 84 % PSG, p = 0.4). Mean operative time was significantly shorter in PSG group (136 ± 29 min vs. 256 ± 58 min, p = 0.0005). Complications of grade I developed in 36 % (wound infection = 10 %, postvoiding dribbling = 18.8 %). Thirty of 69 patients (43 %) had strictures ≥8 cm, and 39 (57 %) had strictures <8 cm-success rate was equal for both subgroups (87 %). Mean blood loss, mean operative time, and incidence of postvoid dribbling were significantly lower in strictures <8 cm. BMG and PSG have comparable success rates in treatment of long anterior urethral strictures. Operative time is significantly longer in BMG. Long-segment strictures are associated with longer operative time, more blood loss, and more occurrence of postvoid dribbling. However, the length of the stricture has no influence on the success rate and functional outcomes of DOU.

    A novel technique to reduce donor site morbidity after radial forearm free flap (RFFF) harvest, using a local full-thickness skin graft (FTSG), is described. Thirty consecutive patients undergoing RFFF for head and neck reconstruction were enrolled in a prospective study. Donor site defect closure was performed with spindle-shaped FTSGs excised from the wavelike skin incision made for the vascular pedicle. Both the removal site of the FTSG on the volar forearm and the covered RFFF donor site healed uneventfully in 29 cases, with no impairment of function related to the skin graft. No skin graft failure and no exposure, tenting, or adherence of the flexor tendons occurred. All patients expressed satisfaction with postoperative pain, the functional outcome, and cosmetic appearance. Primary donor site defect closure could be achieved in all cases with the use of a local FTSG. This graft can be gained at the access incision for the vascular pedicle, avoids expansion of the incision for a local flap technique, and does not prolong wound healing, and thus reduces both donor site and graft site morbidity of the RFFF. This technique leads to an inconspicuous aesthetic result with no apparent relevant functional deficits and avoids the need for a second donor site.

    In breast reconstruction, sensation in the reconstructed breasts affects the patients' quality of life along with its aesthetic outcome. Fortunately, less invasive procedures such as breast-conservative surgery (BCS) and skin-sparing mastectomy (SSM) have greatly contributed to the improved aesthetic outcome in immediate breast reconstruction. However, there are few reports on the recovery of breast sensation after BCS and SSM. We retrospectively reviewed 104 consecutive patients who underwent immediate breast reconstruction with the latissimus dorsi myocutaneous flap between 2001 and 2006 at our institution. The sensations of pain, temperature, touch, and vibration were examined at the nipple and skin envelope during the follow-up period (range: 12-61 months, mean: 31 months), and a stratified analysis was performed to determine the critical factors affecting the sensation recovery after BCS and SSM. We found that large breast size significantly impaired the recovery of sensation in the nipple and skin envelope after BCS as well as SSM. Older age and high body mass index value were the factors which negatively affected the sensation in the skin envelope after SSM. While all our BCS patients underwent postoperative radiation therapy, it did not negatively affect the recovery of sensation in SSM patients. On the basis of these findings, we could further improve the sensation of the reconstructed breasts after BCS and SSM. Especially after SSM, the use of innervated flaps is recommended in the patients with large breast, increased age, or obesity when the nipple-areola complex is resected.

    Full Text Available La reconstrucción auricular es una de las más difíciles ya que implica reproducir las sofisticadas y delicadas formas del pabellón auricular. Cuando hay que resecar piel en la oreja por un cáncer cutáneo y dejamos expuesto el cartílago, sin pericondrio, suele suceder que al colocar injertos no hay una integración adecuada de los mismos por las caprichosas formas y relieves del pabellón auricular; cuando es necesario resecar el pericondrio estamos obligados a cubrir el defecto con un colgajo y no con un simple injerto. Frente a esta dificultad técnica, diseñamos un colgajo ricamente vascularizado que preserva el cartílago no afectado con una buena cubierta y al mismo tiempo respeta la anatomía de la oreja. Para la cobertura del cartílago auricular anterior usamos un colgajo fasciocutáneo posterior que se asemeja a un plato típico de la cocina mexicana que llamamos "quesadilla", donde el cartílago por su color blanco recuerda el queso y el gran colgajo fasciocutaneo recuerda la tortilla que cubre al queso. Este colgajo incluye la piel enrollada del hélix, que en un segundo tiempo retornará a su lugar de origen anatómico mediante una z-plastía asimétrica. Presentamos, de entre una serie de 13 pacientes con carcinoma de pabellón auricular, 2 casos resueltos mediante esta técnica.Auricle reconstruction is one of the most difficult techniques because of the sophisticated and delicates forms of the ear. When we need to remove the auricular skin, preserving the cartilage is very important to keep the shape of the auricle. If treating an auricular skin cancer we find an unaffected cartilage, we can use a skin grafting, but in such delicates forms and curves many times it results inappropriate or the lack of pericondrium difficult skin graft integration. When pericondrium is affected, we will need a skin flap to cover de defect. We designed a rich vascularized flap that preserves the unaffected cartilage with an adequate coverage

    Full Text Available Penile injury due to constriction by a foreign object is a rare known complication, commonly seen in pediatric age group. We report four cases of penile constriction injury in adults due to various foreign objects and different indications. Between October 2014 and March 2016, four patients (mean age 42.5 years presented with penile constriction injury with duration at presentation ranging from 18 h to 2 months. One patient had complete transection of the corpus and penile urethra. Three patients were managed successfully with daily dressings followed by split-skin grafting in one patient. One patient required delayed primary suturing after the resolution of local edema. The outcome was satisfactory in all patients with retained erectile function. Early medical attention and management is the key to success in penile constriction injury cases and to avoid complications and morbidity. Prompt removal can be challenging in cases of metal foreign bodies.

    To investigate the aesthetic effect of wound repair with flaps. One thousand nine hundred and ninety-six patients with 2082 wounds hospitalized from January 2004 to December 2011. These wounds included 503 deep burn wounds, 268 pressure sores, 392 soft tissue defects caused by trauma, 479 soft tissue defects due to resection of skin cancer and mole removal, 314 soft tissue defects caused by scar excision, and 126 other wounds. Wound area ranged from 1.5 cm x 1.0 cm to 30.0 cm x 22.0 cm. Sliding flaps, expanded flaps, pedicle flaps, and free flaps were used to repair the wounds in accordance with the principle and timing of wound repair with flaps. Five flaps showed venous congestion within 48 hours post-operation, 2 flaps of them improved after local massage. One flap survived after local heparin wet packing and venous bloodletting. One flap survived after emergency surgical embolectomy and bridging with saphenous vein graft. One flap showed partial necrosis and healed after skin grafting. The other flaps survived well. One thousand three hundred and twenty-one patients were followed up for 3 months to 2 years, and flaps of them were satisfactory in shape, color, and elasticity, similar to that of normal skin. Some patients underwent scar revision later with good results. Application of suitable flaps in wound repair will result in quick wound healing, good function recovery, and satisfactory aesthetic effect.

    Scrotal elephantiasis is a pathology of often unknown etiology. Symptomatology is characterized by an oedematius infiltration of skin and subcutaneous tissue, hard-bound aspect and purplished color. The scrotum, the penis and the perineal area are gradually affected. This pathology is very invalidating for the patient, on functional, sexual and aesthetic aspects. The authors present the case of a 58-year-old man with an enormous scrotal mass invading the penis and drowning the testicular elements, which were impossible to palpate. The aetiology was determined by exclusion and an iatrogenic origin following the cure of bilateral inguinal hernia was retained. Resection of the scrotal mass was performed. The reconstruction of the scrotal purse and the cutaneous sleeve of the penis were carried out using local flaps of the remaining healthy skin.

    Full Text Available We herein report a case of clear cell carcinoma arising from endometriosis in the groin in a 53-year-old woman. The findings of MRI and FDG/PET-CT indicated a malignant tumor, and surgical biopsy confirmed adenocarcinoma of the female genital tract. The tumor including a part of the abdominal rectus muscle and rectus sheath, subcutaneous fat, skin, and the right inguinal ligament was resected en bloc. The defect in the abdominal wall was reconstructed with a fascia lata tensor muscle skin flap. The tumor was composed of clear cell adenocarcinoma arising from extrapelvic endometriosis. The patient received chemotherapy with gemcitabine and carboplatin for 6 cycles and had no evidence of recurrence 7 months after the treatment. We herein described the diagnosis and surgical management of endometriosis-associated carcinoma in the groin.

    Full Text Available Penile augmentation has been reported in the literature by injecting various materials. This study reports our experience in management of penile augmentation complications associated with selfpenile injection of silicone liquid. After a careful ultrasound study, the penile skin was excised through a circumferential sub-coronal incision and dissected with the silicon mass. Histology was well-compatible with silicone granulomas. The patient was discharged after 24 hours. Ultrasonography has permitted preoperatively to determine if the plane between the indurated inflammatory tissue and the Buck’s fascia was preserved for the complete surgical excision of affected tissue.

    This review will highlight recent advances in the field of penile reconstructive surgery in the paediatric and adult population. It is based on the work published during the year 2001. Besides the anatomical and histological studies of the penis, major contributions have been described in congenital and acquired penile anomalies. Also, a few new techniques and modifications of old procedures are described in order to improve the final functional and aesthetic outcome. The techniques for penile enlargement present a trend in the new millennium, but are still at the stage of investigation.

    Prosthesis-assisted penile reconstruction has been performed extensively to restore a cosmetically acceptable phallus. However, a large number of patients will undergo revision surgery for various prosthesis-related complications. To develop a 1-stage prosthesis-free dynamic cavernosa reconstruction method using bilateral innervated gracilis muscles and to investigate the feasibility and reliability of the surgical design. 10 fresh cadavers were dissected to assess the availability of bilateral gracilis muscles for functional cavernosa rebuilding. 11 mongrel female dogs were involved in the penile reconstruction surgery. The neophallus consisted of bilateral gracilis muscles as the neo-cavernosa, a right gracilis skin flap as the neourethra, and a lower abdominal flap with an anterior rectus sheath as the skin envelope and neo-tunica albuginea. The function and structure of the neo-phalli were assessed 7 months postoperatively. The neurovascular pedicle length of the gracilis muscles and the volume of the gracilis venter musculi were measured in the cadaveric investigation. The average dimensions of the canine neo-phalli at rest and during electrostimulated erection were obtained and the muscular fatigue-resistant curve was drawn. Histologic evaluations also were performed. The neurovascular pedicle length and volume of the gracilis muscles were sufficient to yield a nearly normal appearance of the neo-cavernosa in the cadaveric and animal studies. The muscular fatigue-resistant curve demonstrated adequate length, stiffness, and duration of erection of the neo-phalli to accomplish normal coitus. Histologic evaluations showed an intact neourethra and nearly normal muscle structure in the inner layer of the canine neo-cavernosa, except for significantly increased amount of collagen fibers and type I/III collagen ratio in the outer layer of the neo-cavernosa. The percentage of type II (fatigue-prone) muscle fibers did not change significantly. Our preclinical

  18. Penile implants among prisoners-a cause for concern?

    Directory of Open Access Journals (Sweden)

    Lorraine Yap

    Full Text Available BACKGROUND: We report the prevalence of penile implants among prisoners and determine the independent predictors for having penile implants. Questions on penile implants were included in the Sexual Health and Attitudes of Australian Prisoners (SHAAP survey following concerns raised by prison health staff that increasing numbers of prisoners reported having penile implants while in prison. METHODS: Computer-Assisted Telephone Interviewing (CATI of a random sample of prisoners was carried out in 41 prisons in New South Wales and Queensland (Australia. Men were asked, "Have you ever inserted or implanted an object under the skin of your penis?" If they responded Yes: "Have you ever done so while you were in prison?" Univariate logistic regression and logistic regression were used to determine the factors associated with penile implants. RESULTS: A total of 2,018 male prisoners were surveyed, aged between 18 and 65 years, and 118 (5.8% reported that they had inserted or implanted an object under the skin of their penis. Of these men, 87 (73% had this done while they were in prison. In the multivariate analysis, a younger age, birth in an Asian country, and prior incarceration were all significantly associated with penile implants (p<0.001. Men with penile implants were also more likely to report being paid for sex (p<0.001, to have had body piercings (p<0.001 or tattoos in prison (p<0.001, and to have taken non-prescription drugs while in prison (p<0.05. CONCLUSIONS: Penile implants appear to be fairly common among prisoners and are associated with risky sexual and drug use practices. As most of these penile implants are inserted in prison, these men are at risk of blood borne viruses and wound infection. Harm reduction and infection control strategies need to be developed to address this potential risk.

    Fibrin glue (FG) combines fibrinogen and thrombin, under the presence of factor XIII and calcium chloride, and produces a 'fibrin clot' as would occur through the natural clotting cascade. FG is thought to close over any small vessels including lymphatics that are too small for conventional surgical closure, thereby reducing seroma formation, seroma incidence and related comorbidities. To assess the evidence on the effectiveness of FG in people undergoing breast and axillary surgery and to establish whether FG is an efficient modality to prevent postoperative seroma and seroma-related outcomes. We searched the Cochrane Breast Cancer Group's (CBCG) Specialised Register (9 December 2011), the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 1 2012), MEDLINE (9 December 2011), EMBASE (9 December 2011), LILACS (22 October 2012), SCI-E (22 October 2012), the World Health Organization's International Clinical Trial Registry (9 December 2011) and ClinicalTrials.gov (22 October 2012). Randomised controlled trials (RCTs) comparing the effectiveness of FG in terms of reducing the postoperative seroma incidence and related comorbidities in people undergoing breast and axillary surgery. At least two review authors independently scrutinised search results, selected eligible studies and extracted the data. The pooled analysis of the extracted data was achieved by the statistical analysis on Review Manager software. The quality of studies was assessed using The Cochrane Collaboration's 'Risk of bias' tool. The search of four standard electronic databases yielded 119 potentially relevant studies but only 18 RCTs involving 1252 people were found suitable for statistical analysis. There was significant heterogeneity among trials and the majority of trials were of poor quality. The use of FG under skin flaps following breast and axillary surgery failed to reduce the incidence of postoperative seroma (risk ratio (RR) 1.02; 95% Confidence Interval (CI) 0.90 to 1.16, P

    records of 6 dogs treated at the Veterinary Teaching Hospital of the University of São Paulo between July 1994 and July 1996 were reviewed for tumor features, skin flap technique and postoperative follow up. The dogs in this study were 3 females and 3 males; the mean age was 9 years. One dog was mixed breed and the other dogs were Poodle (2; Boxer (1; German Shepherd(1 and Pekingeese(1. The majority of tumors (5 tumors were located on the limbs and l was located on the perineal region. Skin flap techniques used were : H- plasty (2, W-plasty(1, transposition flap (2, single pedicle advancement flap (1. The sutures were removed 10 to 15 days after surgery. Five dogs had 100% viability of flap skin and necrosis ocurred in one dog which had a survival of 89% of the flap. One dog died 15 months after the surgery because of nontumor related causes. No evidence of recurrence was noted and tumor free interval ranged from 4-20 months. Wide surgical excision of the canine hemangiopericytoma seems to be an eficient therapy since no recurrence ocurred. Familiarity with techniques of skin flap creation can provide the surgeon with alternatives to close a large wound resulting from tumor excision. Skin flaps can bypass many problems in open wound management including delayed healing and greater expenses.

    Theoretically, a flap can be supplied by any perforator based on the angiosome theory. In this study, the technique of free-style perforator flap dissection was used to harvest a pedicled or free skin flap from a previous free flap for a second difficult reconstruction. The authors call this a free-style puzzle flap. For the past 3 years, the authors treated 13 patients in whom 12 pedicled free-style puzzle flaps were harvested from previous redundant free flaps and recycled to reconstruct soft-tissue defects at various anatomical locations. One free-style free puzzle flap was harvested from a previous anterolateral thigh flap for buccal cancer to reconstruct a foot defect. Total flap survival was attained in 12 of 13 flaps. One transferred flap failed completely. This patient had received postoperative radiotherapy after the initial cancer ablation and free anterolateral thigh flap reconstruction. Another free flap was used to close and reconstruct the wound. All the donor sites could be closed primarily. The free-style puzzle flap, harvested from a previous redundant free flap and used as a perforator flap to reconstruct a new defect, has proven to be versatile and reliable. When indicated, it is an alternative donor site for further reconstruction of soft-tissue defects.

    Full Text Available PURPOSE: To evaluate the effects of the histamine iontophoresis on the random skin flap viability in rats. METHODS: Sixty adult male Wistar rats were used. A cranially-based dorsal skin flap measuring 10 x 4 cm was raised and a plastic barrier was placed between the flap and its bed. After the surgical procedure, the animals were randomized into four groups (G1-G4 (n=15 each group as follows: G1 (control - sham electrical stimulation, G2 (electrical stimulation - direct current electrical stimulation, G3 (histamine - histamine and sham electrical stimulation and G4 (histamine iontophoresis - transdermal iontophoresis of histamine. In all groups the procedures were performed immediately after the surgery and on the two subsequent days. The percentage of flap necrosis was measured on the seventh postoperative day. RESULTS: The mean and the respective standard deviation of the percentage of flap necrosis areas were as follows: G1 (control - 47.87 ± 9.13%, G2 - 51.49 ± 8.19%, G3 - 46.33 ± 8.32% and G4 - 30.82 ± 11.25%.

    Ten patients with penile cancer were treated with radiation therapy between 1968 and 1973. Nine of ten remain free of disease though in 1 patient a new penile primary developed eight years after the radiation therapy and was treated by partial penectomy. One patient died following surgery for ''bleeding ulcer.'' He was free of penile cancer five years after radiation. The most common complication is urethral stricture and skin telangiectasia

    We present a novel technique using ventral slit with scrotal skin flaps (VSSF) for the reconstruction of adult buried penis without skin grafting. An initial ventral slit is made in the phimotic ring, and the penis is exposed. To cover the defect in the ventral shaft skin, local flaps are created by making a ventral midline scrotal incision with horizontal relaxing incisions. The scrotal flaps are rotated to resurface the ventral shaft. Clinical data analyzed included preoperative diagnoses, length of stay, blood loss, and operative outcomes. Complications were also recorded. Fifteen consecutive patients with a penis trapped due to lichen sclerosus (LS) or phimosis underwent repair with VSSF. Each was treated in the outpatient setting with no perioperative complications. Mean age was 51 years (range, 26-75 years), and mean body mass index was 42.6 kg/m(2) (range, 29.8-53.9 kg/m(2)). The majority of patients (13 of 15, 87%) had a pathologic diagnosis of LS. Mean estimated blood loss was 57 cc (range, 25-200 cc), mean operative time was 83 minutes (range, 35-145 minutes), and all patients were discharged on the day of surgery. The majority of patients (11 of 15, 73.3%) remain satisfied with their results and have required no further intervention. Recurrences in 3 of 15 (20.0%) were due to LS, panniculus migration, and concealment by edematous groin tissue; 2 of these patients underwent subsequent successful skin grafting. VSSF is a versatile, safe, and effective reconstructive option in appropriately selected patients with buried penis, which enables reconstruction of penile shaft skin defects without requiring complex skin grafting.

We registered indications, flap size and localization, success rate, and complications. Most importantly, we describe a simple approach to the design of freestyle pedicled perforator flaps and elaborate on technical aspects...

  8. Short-Term Memory Impairment and Left Dorsolateral Prefrontal Cortex Dysfunction in the Orthostatic Position: A Single Case Study of Sinking Skin Flap Syndrome

    Directory of Open Access Journals (Sweden)

    Luca Sebastianelli

    2015-01-01

    Full Text Available We describe the case of a patient who underwent craniectomy for hemorrhage of the left parietal lobe. Three weeks later, orthostatic memory impairment was detected as initial symptom of sinking skin flap syndrome (SSFS. This deficit was examined by neuropsychological testing and associated with a posture-dependent increase in the delta/alpha ratio at the F3 electrode, an electroencephalographic (EEG index related to brain hypoperfusion. This EEG spectral alteration was detected in a brain region that includes the left dorsolateral prefrontal cortex, an area known to be involved in memory processing; therefore we hypothesize that SSFS induced reversible hypoperfusion of this otherwise undamaged cortical region. Neither of these findings was present after cranioplasty. This case suggests that SSFS may induce neuropsychological deficits potentially influencing outcome in the postacute phase and is further evidence supporting the clinical benefits of early cranioplasty.

    Chen, Shao-Liang; Chiou, Tai-Fung

    2007-11-01

    The boomerang flap originates from the dorsolateral aspect of the proximal phalanx of an adjacent digit and is supplied by the retrograde blood flow through the vascular arcades between the dorsal and palmar digital arteries. To provide sensation of the boomerang flap for finger pulp reconstruction, the dorsal sensory branch of the proper digital nerve and the superficial sensory branch of the corresponding radial or ulnar nerve are included within the skin flap. After transfer of the flap to the injured site, epineural neurorrhaphies are done between the digital nerves of the pulp and the sensory branches of the flap. We used this sensory flap in five patients, with more than 1 year follow-up, and all patients achieved measurable two-points discrimination. The boomerang flap not only preserves the proper palmar digital artery but also provides an extended and innervated skin paddle. It seems to be an alternative choice for one-stage reconstruction of major pulp defect.

  12. Penile pharmacoarteriography in impotence

    International Nuclear Information System (INIS)

    Bookstein, J.J.

    1986-01-01

    Conventional arteriography is unreliable in the evaluation of arteriogenic impotence, primarily because vasoconstriction of medium and small arteries can be indistinguishable from organic obstruction. Spinal anesthesia plus intracavernosal injections of papaverine can relieve vasoconstriction, but markedly increase the cost and complexity of penile arteriography. The authors have found that internal pudendal injection of papaverine and nitroglycerin provides effective dilation and allows penile arteriography to be performed on an outpatient basis. Arteriographic quality is further enhanced by selective internal pudendal injections, the use of highly concentrated nonionic agents, and direct magnification

    Full Text Available Context: Despite the abundance of techniques for the repair of Hypospadias, its problems still persist and a satisfactory design to correct the penile curvature with the formation of neourethra from the native urethral tissue or genital or extragenital tissues, with minimal postoperative complications has yet to evolve. Aim: Persisting with such an endeavor, a new technique for the repair of distal and midpenile hypospadias is described. Materials and Methods: The study has been done in 70 cases over the past 11 years. The "Forked-Flap" repair is a single stage method for the repair of such Hypospadias with chordee. It takes advantage of the rich vascular communication at the corona and capitalizes on the established reliability of the meatal based flip-flap. The repair achieves straightening of the curvature of the penis by complete excision of chordee tissue from the ventral surface of the penis beneath the urethral plate. The urethra is reconstructed using the native plate with forked flap extensions and genital tissue relying on the concept of meatal based flaps. Water proofing by dartos tissue and reinforcement by Nesbit′s prepucial tissue transfer completes the one stage procedure. Statistical Analysis: An analysis of 70 cases of this single stage technique of repair of penile hypospadias with chordee, operated at 3 to 5 years of age over the past 11 years is presented. Results and Conclusion: The Forked Flap gives comparable and replicable results; except for a urethrocutaneous fistula rate of 4% no other complications were observed.

    Penile self-injection of various oils is still carried out among Eastern Europe people for penile girth augmentation despite the potential destructive complications of this practice are well known. Penile reactions to such foreign bodies include scarring, abscess formation, ulceration, and even Fournier's gangrene; voiding problems due to mineral oil self-injection have been reported only once. To our knowledge, we describe the first case of paraffin self-injection for penile girth augmentation presenting with acute urinary retention. A 27-year-old Romanian man presented with severe penile pain and acute urinary retention five years after having practiced repeated penile self-injections of paraffin for penile girth augmentation. The penile shaft was massively enlarged, fibrotic and phymotic; urethral catheterization failed due to severe stricture of the proximal pendulum urethra. The patients refused placement of a suprapubic catheter and underwent immediate penile surgical exploration. The scarred tissue between dartos and Buck's fascia and a fibrotic ring occluding the urethra were removed and the penile skin reconstructed. Pathology confirmed the diagnosis of paraffinoma. The patient resumed normal voiding immediately after catheter removal on second postoperative day; he was very pleased with cosmetic, sexual and voiding results at six weeks, six months and 1 year follow-up. The present report describes a novel complication of penile self-injection for penile girth augmentation. Because of the increasing number of patients seeking penile augmentation, physicians dealing with sexual medicine should pay more attention to such request to prevent the use of non medical treatments that can turn into medical disasters.

    Full Text Available Purpose: To discuss the role and mechanism of action of soft tissue reinforcement interposition flaps (STRIFs in hypospadias repairs (reinforced hypospadiac urethroplasties. Materials and Methods: Between 2000-2005, 120 consecutive hypospadiacs (distal 85, mid 20, proximal 15, who underwent primary reinforced urethroplasties employing different types of STRIFs, were retrospectively analyzed. The STRIFs were highly vascular soft tissue pedicled flaps (devoid of epithelium interposed between neo-urethras and the covering skin to reinforce the neo-urethras against fistula formation. The STRIFs were harvested, without much donor site deformity, from: preputial skin, penile skin and scrotal skin by de-epithelialization. Those from Buck′s fascia, corpus spongiosum and tunica vaginalis are STRIFs without epithelium anyway, therefore do not need de-epithelialization. Redo urethroplasties and micropenises were not included. Seven patients were excluded because they had incomplete follow-up. The remaining 113 (distal 84, mid 17, proximal 12 were followed up for nine to 40 months for number, size, location, spontaneous closure and persistence of urethro-cutaneous fistula (UCF, and other complications with regard to the severity of hypospadias, method of neourethral re-construction, types of STRIFs employed and skin cover used. A total of 158 STRIFs and 124 skin covers were used in 113 hypospadiac urethroplasties. Results: The first surgery was curative in 74 (65% of 113 patients. In the remaining 39 (35%, various complications included 12 urethro-cutaneous fistulas (UCFs, 10 urethral strictures, six cases each of penile torsion and meatal stenosis and five cases each of superficial necrosis and poor cosmesis. Of these 39 patients, 25 (64% recovered with conservative treatment and 14 (36% required re-operation, i.e. UCFs and strictures in four cases each and penile torsion, meatal stenosis and dog-ears in two cases each.

    2015-11-01

    Reconstruction of the head and neck is a challenge for otolarygology surgeons, maxillofacial surgeons as well as plastic surgeons. Defects caused by the resection and/or trauma should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Deltopectoral flap is a one such flap from chest and neck skin mainly used to cover the facial defects. This study report a patient presenting with tragic Road Traffic Accident (RTA) admitted to maxillofacial surgery department at Ramadi Teaching Hospital, Anbar province, Iraq. An incision, medially based, was done and deltopectoral fascio-cutaneous flap was used for surgical exposure and closure of defects after RTA. There was no major complication. Good aesthetic and functional results were achieved. Deltopectoral flap is an excellent alternative for the reconstruction of head and neck. Harvesting and application of the flap is rapid and safe. Only a single incision is sufficient for dissection and flap elevation.

    Objective was to present our experience with surgical and conservative management of penile fracture. This prospective study was carried out in the Urology and Nephrology Center, at Al-Thawra General and Teaching Hospital, Sana'a, Yemen from June 2003 to September 2007 and included 30 patients presenting with penile fracture. Diagnosis was made clinically in all our patients. Six patients with simple fracture were treated conservatively while 24 patients with more severe injuries were operated upon. Patient's age ranged from 24-52 years (mean 31.3 years) 46.7% of patients were under the age of 30 years and 56.7% were unmarried. Hard manipulation of the erect penis for example during masturbation was the most frequent mechanism of fracture in 53.3% of patients. Solitary tear was found in 22 patients and bilateral corporal tears associated with urethral injury were found in 2 patients. Corporal tears were saturated with synthetic absorbable sutures and urethral injury was repaired primarily. All operated patients described full erection with straight penis except 3 of the 8 patients who were managed by direct longitudinal incision, in whom mild curvature during erection was observed. The conservatively treated patients described satisfactory penile straightness and erection. The optimal functional and cosmetic results are achieved following immediate surgical repair of penis fracture. Good results can also be obtained in some selected patients with conservative management. (author)

    Full Text Available This article considers the impact and outcomes of both treatment and underlying condition of penile anomalies in adolescent males. Major congenital anomalies (such as exstrophy/epispadias are discussed, including the psychological outcomes, common problems (such as corporal asymmetry, chordee, and scarring in this group, and surgical assessment for potential surgical candidates. The emergence of new surgical techniques continues to improve outcomes and potentially raises patient expectations. The importance of balanced discussion in conditions such as micropenis, including multidisciplinary support for patients, is important in order to achieve appropriate treatment decisions. Topical treatments may be of value, but in extreme cases, phalloplasty is a valuable option for patients to consider. In buried penis, the importance of careful assessment and, for the majority, a delay in surgery until puberty has completed is emphasised. In hypospadias patients, the variety of surgical procedures has complicated assessment of outcomes. It appears that true surgical success may be difficult to measure as many men who have had earlier operations are not reassessed in either puberty or adult life. There is also a brief discussion of acquired penile anomalies, including causation and treatment of lymphoedema, penile fracture/trauma, and priapism.

    2002-07-01

    The boomerang-shaped latissimus dorsi musculocutaneous flap for breast reconstruction offers a stable platform for breast reconstruction. It allows for maximal aesthetic results with minimal complications. The authors describe a skin paddle to obtain a larger volume than either the traditional elliptical skin paddle or the extended latissimus flap. There are three specific advantages to the boomerang design: large volume, conical shape (often lacking in the traditional skin paddle), and an acceptable donor scar. Thirty-eight flaps were performed. No reconstruction interfered with patient's ongoing oncological regimen. The most common complication was seroma, which is consistent with other latissimus reconstructions.

    This study assessed the management of patients requesting penile length enhancement by division of the penile suspensory ligament. From September 1998 to January 2005, 42 patients with a variety of etiologies were included; all underwent division of the penile suspensory ligament. The outcome was assessed objectively based on increase in flaccid stretched penile length (SPL) and subjectively using the rates of patient satisfaction. The mean increase in SPL was 1.3+/-0.9 cm (range, -1 to +3 cm), with the addition of a silicone spacer placed between the pubis and penis giving a better outcome (p<0.05). The overall patient satisfaction rate was 35% but lower in the group with penile dysmorphic disorder at 27%. Division of the penile suspensory ligament or other augmentation techniques may increase penile length but usually not to a degree that satisfies the patient. Men with penile dysmorphic disorder often have unrealistic expectations regarding the outcome of surgical intervention and should be encouraged to seek psychological help primarily, with surgery reserved as the last resort.

  4. Complications of surgery for radiotherapy skin damage

    1982-01-01

    Complications of modern surgery for radiotherapy skin damage reviewed in 28 patients who had 42 operations. Thin split-thickness skin grafts for ulcer treatment had a 100 percent complication rate, defined as the need for further surgery. Local flaps, whether delayed or not, also had a high rate of complications. Myocutaneous flaps for ulcers had a 43 percent complication rate, with viable flaps lifting off radiated wound beds. Only myocutaneous flaps for breast reconstruction and omental flaps with skin grafts and Marlex mesh had no complications. The deeper tissue penetration of modern radiotherapy techniques may make skin grafts and flaps less useful. In reconstruction of radiation ulcers, omental flaps and myocutaneous flaps are especially useful, particularly if the radiation damage can be fully excised. The pull of gravity appears detrimental to myocutaneous flap healing and, if possible, should be avoided by flap design

    Full Text Available Subcutaneous penile insertion of foreign bodies is a practice performed globally but has mostly been reported outside of the United States. An incarcerated 29-year-old Caucasian male in a midwestern prison whittled a domino into a dog bone shape and placed it into his ventral penile subcutaneous tissue. He presented to our facility with erosion of the corners of the foreign body through his skin without evidence of infection. Self-insertion of foreign bodies into penile subcutaneous tissue by incarcerated American men for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation.

    Interpolation flaps are commonly used in plastic surgery to cover wide and deep defects. The need to, wait for 2 to 3 weeks until the division of the pedicle still, however, poses a serious challenge, not only extending treatment and hospital stay, but also increasing hospital expenses. To solve this problem, we have aimed to use the angiogenic potential of stem cells to selectively accelerate neovascularization with a view to increasing the viability of interpolation flaps and achieving early pedicle removal. A total of 32 rats were allocated to 2 groups as control (N = 16) and experiment (N = 16). The cranial flaps 6 × 5 cm in size located on the back of the rats were raised. Then, a total suspension containing 3 × 10(6) adipose-derived mesenchymal stem cells (ADSC) tagged with a green fluorescent protein (GFP) was injected diffusely into the distal part of the flap, receiving bed, and wound edges. In the control group, only a medium solution was injected into the same sites. After covering the 3 × 5 cm region in the proximal part of the area where the flap was removed, the distal part of the flap was adapted to the uncovered distal area. The pedicles of 4 rats in each group were divided on postoperative days 5, 8, 11, and 14. The areas were photographed 7 days after the pedicles were released. The photographs were processed using Adobe Acrobat 9 Pro software (San Jose, CA) to measure the flap survival area in millimeters and to compare groups. Seven days after the flap pedicle was divided, the rats were injected with 250 mCi Tc-99 mm (methoxy-isobutyl-isonitrie) from the penile vein, and scintigraphic images were obtained. The images obtained from each group were subjected to a numerical evaluation, which was then used in the comparison between groups. The flaps were then examined by histology to numerically compare the number of newly formed vessels. Neovascularization was also assessed by microangiography. In addition, radiographic images were obtained by

    Full Text Available For some patients with impotence and concomitant severe tunical/corporeal tissue fibrosis, insertion of a penile prosthesis is the only option to restore erectile function. Closing the tunica over an inflatable penile prosthesis in these patients can be challenging. We review our previous study which included 15 patients with severe corporeal or tunical fibrosis who underwent corporeal reconstruction with autologous rectus fascia to allow placement of an inflatable penile prosthesis. At a mean follow-up of 18 months (range 12 to 64, all patients had a prosthesis that was functioning properly without evidence of separation, herniation, or erosion of the graft. Sexual activity resumed at a mean time of 9 weeks (range 8 to 10. There were no adverse events related to the graft or its harvest. Use of rectus fascia graft for coverage of a tunical defect during a difficult penile prosthesis placement is surgically feasible, safe, and efficacious.

    2018-01-01

    Full Text Available Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5, anterior tibia (n=1, posterior axilla (n=1, ischium (n=1, and trochanter (n=2. The template for a bilateral flap was used on the sacrum (n=8, arm (n=1, and anterior tibia (n=1. The causes of the defects were meningocele (n=3, a decubitus ulcer (n=5, pilonidal sinus (n=3, and skin tumor excision (n=10. The meningocele patients were younger than 8 days. The mean age of the adult patients was 50.4 years (range, 19–80 years. All the donor areas of the flaps were closed primarily. None of the patients experienced wound dehiscence or partial/total flap necrosis. The templates guided surgeons regarding the length and the placement of the incision for a V-Y rotation advancement flap according to the size of the wound. In addition, they could be used for the training of residents.

    The male genitalia cosmetic surgery matches an ever growing need. The aim of this study is to describe our penile lengthening and widening procedures, the benefits and complications that could result from it. We perform these procedures since 1992 and treated close to 2000 patients. Thanks to our expertise and after succeeding in standardizing our techniques, we achieved a retrospective survey on 103 patients operated between 2004 and 2006. We describe here the two processes of our operating technique and we analyse the results obtained 1 month, 3 months and 1 year after the surgery. In most cases, combining a penis adipose tissue grafting, a suspensory ligament section and an adequate skin plasty is proven to be necessary in order to obtain both lengthening and widening increases. One year later, the increase is about 2.7 cm in length, corresponding to 28%, and 2.6 cm in circumference, corresponding to 27%. The complications (cutaneous necrosis, haematoma, lymphoedema, disharmonies), whenever they may exist, are most of the time spontaneously resolutive. Combining a penile fat tissue grafting with a suspensory ligament section allows us to answer to most of patients' expectations. However, several liposculpturing sessions might be necessary in order to get satisfactory results. Copyright 2009 Elsevier Masson SAS. All rights reserved.

  14. The effect of atorvastatin on survival of rat ischemic flap

    2013-04-01

    Full Text Available Management of skin avulsion with tissue exposure is a challenge for plastic surgeons. Clinical observations have suggested that longer survival of skin flap prevents further contamination and infection. Less well known is the role of atorvastatin in avulsion skin flap. Therefore, we attempted to determine whether atorvastatin could alleviate avulsion skin flap in a rat model. Twenty male Sprague–Dawley rats were randomized into two groups: the atorvastatin group and the control. Before operation, each rat received an initial blood perfusion scan as baseline data. Then, each rat received an operation of skin flap incision, elevation, and resuturing to the original position under general anesthesia. Another blood perfusion scan was performed on each rat 30 minutes, 4 days, and 7 days postoperatively. On the 7th postoperative day, the necrotic area of skin flap was measured as the skin flap viability. The skin flap tissues at 2.5 and 5 cm distal to the skin flap base were collected for histopathological analysis, as well as measurement of vascular endothelial growth factor (VEGF mRNA expression, and vascular density. Compared with 30 minutes postoperation, there was a significant increase in the ratio of skin flap blood perfusion on the 4th and 7th days postoperation in both control and atorvastatin groups (p<0.05. Compared with the control group, there was a significant decrease in necrotic area, significant increase in ratio of skin flap blood perfusion on postoperation days 4 and 7, and significant increase in vascular density under high field at 2.5 cm distal to the base of skin flap in the atorvastatin group (p<0.05. The VEGF121 and VEGF165 mRNA expression at 2.5 cm distal to the base of skin flap differed significantly between the two groups (p<0.05. Compared with the control group, atorvastatin treatment improved skin flap blood perfusion, vascular density, and necrotic area dependent on VEGF mRNA expression.

    Steatocystoma simplex is an uncommon skin lesion with a histological pattern that is identical to that of steatocystoma multiplex. We are reporting this case of steatocystoma simplex for its uncommon location in the penile foreskin, and its occurrence in a Wapishana man. A 56-year-old man of Wapishana ethnicity presented with complaints of referred penile discomfort and pain during sexual intercourse for 5 years. A physical examination revealed a mobile, compressible subcutaneous non-tender mass of 4 cm diameter located on the left-side of his penile foreskin. There were no signs of inflammation, no grip on the penile shaft, and no urethral discharge or enlargement of lymph nodes. We found no evidence of other cysts on cutaneous examination. We performed classical excision of the lesion under local anesthesia and confirmed the diagnosis of steatocystoma with the pathological report. As there were no complications, we discharged him the same day. Steatocystoma can be considered a differential diagnosis for cystic lesions on and around the penis.

    2013-07-01

    Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. A literature review was conducted on Medline considering the articles listed until January 2012. Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

  19. The Etiology and Treatment of the Softened Phallus after the Radial Forearm Osteocutaneous Free Flap Phalloplasty

    Seok-Kwun Kim

    2012-07-01

    Full Text Available BackgroundThe radial forearm osteocutaneous free flap is considered to be the standard technique for penile construction. One year after their operation, most patients experience a softened phallus, so that they suffer from difficulties in sexual intercourse. In this report, we present our experience with phalloplasty by radial forearm osteocutaneous free flap, as well as an evaluation of the etiology and treatment of the softened phallus.MethodsBetween March 2005 and February 2010, 58 patients underwent phalloplasty by radial forearm osteocutaneous free flap. Most of their neophallus had been softened subjectively and among them, 12 patients who wanted correction were investigated. We performed repetitive fat injection, artificial dermis grafting, silicone rod insertion, and rib bone with cartilaginous tip graft. Physical examination, plain radiograph, computed tomography, bone scintigraphy, and satisfaction scores were investigated.ResultsMost of the participants' penises have been softened after phalloplasty, and the skin elasticity had been also decreased. On plain radiograph, the distal end of the bone was self-rounded; however, the bone shape of the neophallus had no significant interval changes or resorption. Computed tomography showed equivocal density of cortical bone. On bone scintigraphy, the bone metabolism was active at 3 months postoperatively, and remained active 9 years postoperatively.ConclusionsThe use of a rib bone with cartilaginous tip graft could be an option for improvement of the softened phallus. Silicon rod insertion is also worth considering for rigidity of the softened phallus. Decreased rigidity due to soft tissue atrophy could be alleviated with repeated fat injection and artificial dermis grafting.

  20. Total endoscopic free flap harvest of a serratus anterior fascia flap for microsurgical lower leg reconstruction

    Erdmann, Alfons

    2014-04-01

    Full Text Available [english] Background: A tremendous number of free flaps have been developed in the past. As the surgical result depends not only on a successful flap transfer but also on the harvest, this paper details the procedures for undertaking the first total endoscopic harvest of a serratus fascia flap for free flap transplantation to the lower leg. Patient and methods: In September 2012 we performed the first total endoscopic serratus anterior fascia free flap harvest. The incision of 2.5 cm length was made 10 cm in front of anterior muscle border of the latissimus dorsi at level with the midthorax. After insertion of a flexible laparoscopic single port system we started CO gas insufflation. We used this setting to meticulously prepare a neo cavity between atissimus dorsi and M. serratus anterior. The vessels were dissected and the thoraco-dorsal nerve was separated. With a second auxiliary incision we used a clamp to support the raising of the fascia flap from the underlying muscle. Finally we clipped the vessels to the latissimus dorsi muscle and the flap vessels at the Arteria and Vena axillaris. The flap was extracted via the 2.5 cm incision.Results: We were able to perform a total endoscopic harvest of a serratus fascia flap for free flap reconstruction of soft tissues. With this new operative technique we were able to avoid a long skin incision, which in our view lowers the morbidity at the harvest area.Conclusion: We describe a new method for the total endoscopic harvest of the serratus fascia flap for free flap transfer. The flap was harvested within reasonable time and following surgery leaves the patient with minimal donor site morbidity compared to the open technique.

    To assess the postpubertal outcome of ventral penile curvature repaired in infancy in terms of recurrence and aesthetics. Postpubertal patients treated for hypospadias and ventral penile curvature in infancy at a tertiary medical center were invited to undergo assessment of the quality of the repair. Findings were compared between patients with a straight penis after skin release and patients who required dorsal plication. The cohort included 27 patients of mean age 16.5 years who were reported with straight penis after surgery. Postpubertal curvature was found in 6 of 14 patients (43%) successfully treated by skin release and 10 of 13 patients (77%) who underwent dorsal plication (P = .087). Significant curvature (≥30 degrees) was found in 1 of 14 patients in the skin-release group and 4 of 13 in the dorsal plication group (P = .16). Rates of redo urethroplasty were 2 of 14 (14%) and 5 of 10 (50%), respectively. Patient satisfaction with the appearance of the penis did not differ significantly. Ventral penile curvature repaired in infancy often recurs after puberty. The need for dorsal plication has a trend-level association with recurrence of penile curvature in puberty. It might also be related to the degree of postpubertal penile curvature and the need for redo urethroplasty. Procedure type does not affect patient satisfaction with the postpubertal appearance of the penis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available External urine collecting devices have been a boon to patients of urinary incontinence since their invention in late 90s. They have replaced the need for uncomfortable indwelling catheters in these patients. As safe as they may be, ghastly complications have occurred infrequently, mostly due to their inappropriate application. Such penile and urethral complications add to the morbidity of the patients significantly. They can be easily avoided by following few simple steps of catheter care, thus emphasizing the need to aware clinicians and health care workers about the correct application methods. Here we discuss a case of 60 year old male who developed penile skin necrosis and urethral fistula due to chronic use of condom catheter.

    Penile cancer is a disease with a high morbidity and mortality. Its prevalence is relatively rare, but the highest in some developing countries. Insight into its precursor lesions, pathogenesis and risk factors offers options to prevent this potentially mutilating disease. This review presents an overview of the different histologically and clinically identified precursor lesions of penile cancer and discusses the molecular pathogenesis, including the role of HPV in penile cancer development. A systematic review of the literature evaluating penile carcinogenesis, risk factors and molecular mechanisms involved. Careful monitoring of men with lichen sclerosis, genital Bowen's disease, erythroplasia of Queyrat and bowenoid papulosis seems useful, thereby offering early recognition of penile cancer and, subsequently, conservative therapeutic options. Special attention is given to flat penile lesions, which contain high numbers of HPV. Their role in HPV transmission to sexual partners is highlighted, but their potential to transform as a precursor lesion into penile cancer has been unsatisfactorily explored. Further research should not only focus on HPV mediated pathogenic pathways but also on the non-HPV related molecular and genetic factors that play a role in penile cancer development. Options for prevention of penile cancer include (neonatal) circumcision, limitation of penile HPV infections (either by prophylactic vaccination or condom use), prevention of phimosis, treatment of chronic inflammatory conditions, limiting PUVA treatment, smoking cessation and hygienic measures.

    Defects after ablative tongue cancer surgery can be reconstructed by split-thickness skin grafts or free microvascular flaps. The different surgical options may influence costs, reimbursement, and therefore possible profits. Our goal was to analyze the development of these parameters for different procedures in head and neck reconstruction in Germany over the last decade. After tumor resection and neck dissection of tongue cancer, three different scenarios were chosen to calculate costs, reimbursement, length of stay (LoS), and profits. Two options considered were reconstruction by split-thickness skin graft with (option Ia) and without (option Ib) tracheotomy. In addition, we analyzed microvascular reconstruction with radial forearm flap (option II). Furthermore, unsatisfactory results after options Ia and Ib may make secondary tongue plastic with split-thickness skin grafting necessary (option I+). The calculations were performed considering the German Diagnosis Related Group (DRG) system and compared to the specific DRG cost data of 250 German reference hospitals. The overall average length of stay (aLoS) declined from 16.7 to 12.8 days with a reduction in every option. Until 2011, all options showed similar accumulated DRG reimbursement. From 2012 onwards, earnings almost doubled for option II due to changes in the DRG allocation. As was expected, the highest costs were observed in option II. Profits (reimbursement minus costs) were also highest for option II (mean 2052 €, maximum 3630 Euros in 2015) followed by options Ia (765 €) and Ib/I+ (681 €). Average profits over time would be 17 to 19% higher if adjusted for inflation. We showed the development of the DRG allocation of two commonly used methods of reconstruction after ablative tongue cancer surgery and the associated LoS, reimbursement, costs, and profits. As expected, the highest values were found for microvascular reconstruction. Microvascular reconstruction may also be the primary choice of

    Perineal defects are encountered ever more frequently, in the treatment of vulvar cancers or abdominoperineal resection. The surgical treatment of vulvar cancer leads to significant skin defect. The aim of the reconstruction is not to provide volume but rather to resurface perineum. We propose a new solution to cover the extensive skin defect remaining after excision. We report 3 patients who underwent large excision for vulvar cancer, with lymph node dissection. For reconstruction, we performed 3 advancement flaps. Two V-Y flaps cantered on the infra-gluteal folds and based on pudendal perforator arteries were used to cover the postero-lateral parts of the defect. The third advancement flap from the superior aspect of the defect was a Y-V Mons pubis flap. The defects were successfully covered by the 3 flap technique. The first patient suffered a non-union that slowly healed by secondary intention. For the other cases, we used the same technique, but applied negative pressure wound therapy on the sutures, with excellent results. The 3 flap technique is a simple and reliable method and the donor site morbidity is minimal. It can be realised without changing the position of the patient after tumour excision, and does not require delicate perforator dissection. This surgical option can be easily applied, allowing better management of these cases. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available A new axial pattern flap based on the terminal branches of the medial circumflex femoral artery is described for coverage of ischial pressure sore. Based on the terminal branches of the transverse branch of medial circumflex femoral artery, which exit through the gap between the quadratus femoris muscle above and the upper border of adductor magnus muscle below, this fascio cutaneous flap is much smaller than the posterior thigh flap but extremely useful to cover ischeal pressure sores. The skin redundancy below the gluteal fold allows a primary closure of the donor defect. It can also be used in combination with biceps femoris muscle flap.

    Problems in the surgical treatment of radionecrotic ulcers, using a myocutaneous flap, have been reviewed in 21 patients. These problems included poor wound healing, radiation damage to important nerves and vessels there by making dissection difficult, malignant changes, infections, continuing necrosis of the tissue, and bleeding during surgery and secondary hemorrhaging. The use of a myocutaneous flap has many advantages when compared with conventional flaps and free skin grafts in the reconstruction of radionecrotic ulcers. Flap survival was good, but an incomplete excision of the ulcer delayed primary wound healing. Therefore, complete excision of the radionecrotic ulcer is imperative. (author)

    The purpose of this retrospective study was to report the outcomes of 19 dogs and 1 cat undergoing reverse saphenous conduit flap between 1999 and 2016. Reverse saphenous conduit flap was used to treat traumatic wounds and wounds resulting from tumor excision in the hind limb; the majority of cases had medial shearing injuries. All animals had complete flap survival. In five animals (20%), minor donor site dehiscence occurred, which did not require surgery. Other postoperative complications included signs of severe venous congestion in one dog. Reverse saphenous conduit flap is a useful technique to repair skin defects of the distal hind limb.

    A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis. The biopsy result was thickening of the horny layer epidermis with only a foreign body granuloma composed of inflammatory cells, and did not lead to a definitive diagnosis. Thoraca-abdominal computed tomography revealed axillary lymphadenopathy with necrosis. Suspecting tuberculosis lymphadenitis, we performed T-spot and QuantiFERONtests. The result was T-spot negative and QuantiFERONpositive, so we diagnosed the patient with penile tuberculosis, and started antituberculosis medication. In about half a year after the start of treatment the symptoms subsided, and lymphadenopathy showed reduction.

    Malignant disease involving the skin represents a significant work load to the general radiotherapist and can involve interesting diagnostic and therapeutic decisions. Primary skin cancer is also relatively common and there is a need to provide an efficient service in which the first treatment is successful in the majority of patients. The reward for careful attention to technique is very considerable both in terms of clinical cancer control and functional results. Squamous cell carcinoma, basal cell carcinoma, and intra-epidermal carcinoma constitute the majority of the lesions dealt with clinically, but metastatic disease, lymphomas, and malignant melanomas are also referred regularly for opinions and may require radiotherapy. The general principle of the techniques of assessment and radiotherapeutic management to be described are equally applicable to any malignant skin tumour once the decision has been made to accept it for radiotherapy. Dosage and fractionation may have to be adjusted to allow for the nature of the disease process and the intent of the treatment

    Free flap monitoring in autologous reconstruction after nipple-sparing mastectomy remains controversial. The authors therefore examined outcomes in nipple-sparing mastectomy with buried free flap reconstruction versus free flap reconstruction incorporating a monitoring skin paddle. Autologous free flap reconstructions with nipple-sparing mastectomy performed from 2006 to 2015 were identified. Demographics and operative results were analyzed and compared between buried flaps and those with a skin paddle for monitoring. Two hundred twenty-one free flaps for nipple-sparing mastectomy reconstruction were identified: 50 buried flaps and 171 flaps incorporating a skin paddle. The most common flaps used were deep inferior epigastric perforator (64 percent), profunda artery perforator (12.1 percent), and muscle-sparing transverse rectus abdominis myocutaneous flaps (10.4 percent). Patients undergoing autologous reconstructions with a skin paddle had a significantly greater body mass index (p = 0.006). Mastectomy weight (p = 0.017) and flap weight (p < 0.0001) were significantly greater in flaps incorporating a skin paddle. Comparing outcomes, there were no significant differences in flap failure (2.0 percent versus 2.3 percent; p = 1.000) or percentage of flaps requiring return to the operating room (6.0 percent versus 4.7 percent; p = 0.715) between groups. Buried flaps had an absolute greater mean number of revision procedures per nipple-sparing mastectomy (0.82) compared with the skin paddle group (0.44); however, rates of revision procedures per nipple-sparing mastectomy were statistically equivalent between the groups (p = 0.296). Although buried free flap reconstruction in nipple-sparing mastectomy has been shown to be safe and effective, the authors' technique has evolved to favor incorporating a skin paddle, which allows for clinical monitoring and can be removed at the time of secondary revision.

    Lymphoscintigraphy for sentinel node (SN) identification has been extensively validated in breast cancer and melanoma. The aim of this study was to evaluate the findings of lymphoscintigraphy for SN identification in carcinoma of the penis. Lymphoscintigraphy was performed in 74 consecutive patients (mean age 62.2 years, range 28-87 years) with clinically lymph node-negative squamous cell carcinoma of the penis (stage T2 or greater). Following local anaesthesia by xy-locaine 10% spray, technetium-99m nanocolloid (mean dose 64.8 MBq, range 40-131 MBq) in a volume of 0.3-0.4 ml was injected intradermally around the tumour. Shortly after injection, a 20-min dynamic study was performed with a dual-head gamma camera; subsequently, static anterior and lateral images were obtained at 30 min and 2 h using simultaneous cobalt-57 flood source transmission scanning. 57 Co-assisted skin marking defined SN location for gamma probe/blue dye-guided biopsy, which was performed the next day. The SN visualization rate was 97% (72/74). Lymphatic drainage was bilateral in 81% of the cases (58/72), exclusively to the left groin in 13% (9/72) and only to the right groin in 6%. Bilateral lymph node drainage was synchronous in 38% (22/58) and asynchronous in 62% (in 18 patients the initial route was the left groin, and in the other 18, the right groin). Visualization before 30 min occurred in 66 patients (93%), in 64 of them (88%) already during the dynamic study. A total of 173 SNs were visualized (85 in the right groin, 88 in the left groin). Pitfalls were caused by inguinal skin contamination during injection (four patients) and intracavernous administration (one patient). At surgery, a total of 161 SNs were identified and removed. Sixteen patients (22%) had a tumour-positive SN and underwent standard regional lymph node dissection subsequently. During follow-up (median 28 months, range 3-74 months), two patients with a negative SN developed lymph node metastases in the mapped basin

    The current literature provides a wide range of publications on the anthropometry of the penis specifying the relationship between penile dimensions and sex hormones, weight, height and erectile function. But most of the studies involved healthy volunteers or young patients with erectile dysfunction. Our study was conducted in patients with type 2 diabetes. Penile measurements obtained in the present study were compared those of the average Russian man. The patients were divided into groups with preserved and impaired erectile function. Erectile function was also studied relative to the variability of penile dimensions. The effect of DM duration on erectile function was defined. Comparative analysis revealed the relationship between penile anatomical dimensions and erectile function. We studied the effect of type 2 diabetes on the anatomical dimensions and elasticity of the penis, established the relationship between penile dimensions and elasticity of the penis. The correlation between the severity of erectile dysfunction and serum testosterone levels on one side, and penile dimensions on the other was found. The effect of penile dimensions on erectile function in DM patients was also examined. Determining penile dimensions and their variability due to various pathological conditions or processes, may eventually lead to better result of ED management.

    Full Text Available BackgroundGroin dissections result in large wounds with exposed femoral vessels requiring soft tissue coverage, and the reconstructive options are diverse. In this study we reviewed our experience with the use of the pedicled anterolateral thigh and vertical rectus abdominis musculocutaneous flaps in the reconstruction of large groin wounds.MethodsGroin reconstructions performed over a period of 10 years were evaluated, with a mean follow up of two years. We included all cases with large or complex (involving perineum defects, which were reconstructed with the pedicled anterolateral thigh musculocutaneous or the vertical rectus abdominis musculocutaneous (VRAM flaps. Smaller wounds which were covered with skin grafts, locally based flaps and pedicled muscle flaps were excluded.ResultsTwenty-three reconstructions were performed for large or complex groin defects, utilising the anterolateral thigh (n=10 and the vertical rectus abdominis (n=13 pedicled musculocutaneous flaps. Femoral vein reconstruction with a prosthetic graft was required in one patient, and a combination flap (VRAM and gracilis muscle flap was performed in another. Satisfactory coverage was achieved in all cases without major complications. No free flaps were used in our series.ConclusionsThe anterolateral thigh and vertical rectus abdominis pedicled musculocutaneous flaps yielded consistent results with little morbidity in the reconstruction of large and complex groin defects. A combination of flaps can be used in cases requiring extensive cover.

    Various fingertip reconstructions have been reported for situations where microsurgical finger replantation is impossible. One method is the digital artery perforator (DAP) flap. Herein we report 13 DAP flaps for fingertip and finger stump reconstruction following traumatic finger amputations, highlighting modifications to the originally described DAP flap. From October 1998 to December 2007, a total of 13 fingers (11 patients) underwent fingertip and finger stump reconstruction with modified DAP flaps following traumatic finger amputations. We performed six adipocutaneous flaps, three adipose-only flaps, two supercharged flaps and two extended flaps. Flap size ranged from 1.44 to 8 cm(2) (average 3.25 cm(2)). All flaps survived completely with the exception of partial skin necrosis in two cases. One of these cases required debridement and skin grafting. Our initial three cases used donor-site skin grafting. The donor site was closed primarily in the 10 subsequent cases. No patients showed postoperative hypersensitivity of repaired fingertips. Semmes-Weinstein (SW) test result for flaps including a digital nerve branch did not differ from those without (average 4.07 vs. 3.92). Modified DAP flaps allow for preservation of digital length, volume and finger function. They can be raised as adiposal-only flaps or extended flaps and supercharged through perforator-to-perforator anastomoses. The donor defect on the lateral pulp can be closed primarily or by skin grafting. For traumatic fingertip and finger stump reconstructions, DAP flaps deliver consistent aesthetic and functional results.

    2009-11-01

    Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). This fact by itself leads to controversy regarding the true indications for penile enhancement procedures in men without micropenis. One of the typical aspects of penile enhancement is the lack of true methodological evaluation of the more commonly performed procedures. Even recently, only few solid scientific studies are available which can shed some light on results and outcome of these controversial procedures. Although some additional data has emerged during the past year, there is still no consensus in regard to indications and surgical techniques used for penile augmentation or penile girth enhancement. There is further need for more studies to provide a better overview of the value and worthiness of these procedures.

There were 19 cases of other complications at recipient sites such as partial graft loss (8, partial flap necrosis (6 and infection (5. However, these complications were not notable and were resolved with skin grafts.ConclusionsThe free flap is an effective method of lower-extremity reconstruction. Good outcomes can be achieved with complete debridement and the selection of appropriate recipient vessels and flaps according to the recipient site.

    Accurate data regarding the size of the erect penis are of great importance to several disciplines working with male patients, but little high-quality research exists on the subject, particularly in different ethnic groups and for erect penis size. The aim of this study was to create a nomogram of erect penile dimensions in a large sample of Middle Eastern men. A retrospective cohort study of 778 men (mean age 43.7; range 20-82) attending urological outpatient clinics in Saudi Arabia was conducted. Exclusion criteria were age under 18 years, a presenting complaint of small or short penis, Peyronie's disease or complaint of congenital curvature, clinical hypogonadism, and previous penile surgery or trauma. Three erect penile dimensions following induction of erection using intracavernosal injection of Quadrimix. Mean patient body mass index (BMI) was 29.09 (standard deviation [SD] 5.76). The mean suprapubic skin-to-penile tip erect length was 12.53 cm (SD 1.93); the mean erect length from the symphysis pubis to the penile tip was 14.34 cm (SD 1.86); and the mean erect shaft circumference was 11.50 cm (SD 1.74). A nomogram was constructed and statistical analysis performed, demonstrating a weak negative correlation between BMI and erect penile length measured from the suprapubic skin (r = -0.283, P Middle Eastern men can be used as a standard when advising men with small penis anxiety. The importance of measuring erect size and allowing for infra-pubic fat interference in measurement is emphasized. We envisage that this tool can be used to educate and reassure concerned men about the size of their penises. © 2015 International Society for Sexual Medicine.

    To identify post-operative computed tomography (CT) findings associated with delayed flap failures following head and neck cancer surgery. We retrospectively reviewed 60 patients who underwent flap reconstruction after head and neck cancer surgery and post-operative (3–14 days) contrast-enhanced CT scans for suspected complications. Patients were divided into two groups: delayed flap failure patients (patients required flap revision) (n = 18) and flap success patients (n = 42). Clinical data (age, sex, T-stage, type of flap, and time interval between reconstruction surgery and CT) and post-operative CT findings of flap status (maximum dimension of the flap, intra- or peri-flap fluid collection and intra- or peri-flap air collection, fat infiltration within the flap, fistula to adjacent aerodigestive tract or skin, and enhanced vascular pedicle) were assessed and compared between the two groups. CT findings showed that the following flap anomalies were observed more frequently in the delayed flap failure group than in the flap success group: intra- or peri-flap fluid collection > 4 cm (61.1% vs. 23.8%, p < 0.05), intra- or peri-flap air collection > 2 cm (61.1% vs. 2.4%, p < 0.001), and fistula to adjacent aerodigestive tract or skin (44.4% vs. 0%, p < 0.001). The maximum dimension of the flap, fat infiltration within the flap, and enhanced vascular pedicle were not associated with delayed flap failures. A large amount of fluid or air collection and fistula are the CT findings that were associated with delayed flap failures in patients with suspected post-operative complications after head and neck cancer surgery.

    Full Text Available Implantation of an inflatable penile prosthesis (IPP is a well-established definitive solution for erectile dysfunction when conservative treatments fail. Penile implants may shorten the penis. The AMS 700 LGX IPP is in common use but reports on its mechanical reliability, medium-term postsurgical patient satisfaction, and mean penile length preservation are lacking. We investigate the mean penile length, mechanical reliability, and patient satisfaction at 6 and 12 months after implantation of the AMS 700 LGX. This prospective study consecutively enrolled men undergoing first-time IPP implant surgery from February 2009 to April 2012. Stretched flaccid penile length, penile length at 50% and 100% of stiffness (P50 and P100 and International Index of Erectile Function (IIEF and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS scores, were measured at 6 and 12 months postsurgery. Of 45 patients who underwent AMS 700 LGX implantation (median age 61 years and completed 6 months′ follow-up, 36 (80% completed the study. A significant difference in stretched flaccid penile length was seen between 6 and 12 months (P = 0.033. P100 was also significantly increased at 6 and 12 months, with a mean 10% increase (1.3 ± 0.4 cm from baseline to 12 months. Differences in mean IIEF scores at 6 and 12 months were significant for the desired domain (P = 0.0001 and for overall satisfaction (P = 0.002; however, mean EDITS scores at 6 and 12 months were not significantly improved. AMS 700 LGX is a powerful tool for preserving penile length in men undergoing penile prosthesis implantation.

    To evaluate the oncological outcomes of patients with breast cancer after nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM), followed by immediate reconstruction, as compared to conventional mastectomy (CM).SSM/NSM has been increasingly used to treat women with breast cancer who wish to preserve the overlying breast skin, but concern exist regarding its oncological safety due to the potential for residual breast tissue. We report our experience performing SSM/NSM for breast cancer treatment compared to CM with a long follow-up period.All consecutive patients who underwent mastectomy for breast cancer at Asan Medical Center between January 1993 and December 2008 were identified by retrospective medical chart review. The patients who underwent NSM/SSM, followed by immediate breast reconstruction with a pedicled transverse rectus abdominis musculocutaneous flap (TRAM), were compared to the patients who underwent CM in terms of breast-cancer specific survival (BCSS) rate, distant metastasis-free survival (DMFS) rate, and local recurrence (LR) rate.During the study period, 6028 patients underwent mastectomy for breast cancer. Of these, 1032 and 4996 underwent NSM/SSM with TRAM and CM, respectively. Their median follow-up durations were 94.4 (range, 8.1-220.2) and 110.8 (range, 6.1-262.0) months, respectively. Their 5 year BCSS rates were 95.4% and 88.1%, respectively (log-rank, P < .001). Their 5 year DMFS rates were 93.0% and 85.6%, respectively (log-rank, P < .001).Relative to CM, NSM/SSM, followed by immediate breast reconstruction, may be a viable and oncologically safe surgical treatment in selected patients with breast cancer.

    Donor-site morbidity following harvest of the radial forearm free flap was compared with that following harvest of the ulnar forearm free flap. Twenty-eight radial forearm and 27 ulnar forearm flaps were harvested in 55 patients with head and neck defects. Pressure perception was measured with Semmes-Weinstein monofilaments. Cold perception was tested with chloroethyl. Donor-site healing was evaluated. Patients were interviewed about grip and pinch strength and donor-site appearance. In the radial forearm free flap group, pressure perception and cold perception were reduced in the donor hand, whereas in the ulnar group, no differences were observed between the donor and unoperated hands. In the radial forearm group, 15 percent of patients experienced reduced strength in the donor hand, whereas in the ulnar forearm group, none of the patients reported reduced strength in the donor hand. In the radial forearm group, 14 percent had partial or complete loss of the skin graft, whereas in the ulnar forearm group, 4 percent had partial loss of the skin graft. In the radial forearm group, 18 percent of patients were dissatisfied with the appearance of the donor site, and no complaints were reported in the ulnar forearm group. The authors' study shows less donor site-morbidity following harvest of the ulnar forearm free flap than following harvest of the radial forearm free flap. These results emphasize that the ulnar forearm free flap should be considered as an alternative for the radial forearm free flap for reconstruction of soft-tissue defects. Therapeutic, III.

    Full Text Available Introduction: Physicians frequently encounter questions by parents regarding the normal size of a child′s penis. We evaluated normal variations of penile dimensions, correlation of penile length with height, weight, and body mass index (BMI of boys and analyzed the differences in penile dimensions from those reported from other countries. Materials and Methods: A cross-sectional study was conducted at our institution during October 2012-December 2012. A total of 250 subjects (birth to 10 years were evaluated and divided into 10 groups with 1-year interval taking 25 children in each. Penile dimensions measured twice by a single observer with Vernier calipers included the length of flaccid penis fully stretched and diameters at mid-shaft and corona. Diameters were multiplied by pi (π = 3.14 to calculate circumferences. Mean, standard deviation, and range were calculated. Height, weight, and BMI were noted and statistically correlated with the penile length using the Pearson correlation coefficient. Data were compared with similar studies reported on other populations in the past and individually evaluated with every study using Student′s t-test. Results: The mean values for the penile length, mid-shaft circumference, and coronal circumference were 3.34, 3.05, 3.29 cm during infancy, 4.28, 3.86, 4.11 cm during 4-5 years, and 5.25, 4.78, 5.05 cm during 9-10 years, respectively. The penile length increased with advancing age in successive age groups, but it did not have a direct correlation with either height, weight, or BMI. Penile dimensions in North Indian children were found to be statistically smaller in comparison with most studies from other countries. Conclusion: We provide the normal range and variations of penile dimensions in North Indian children.

    Full Text Available Penile hair tourniquet (PHT is a painless form of penile ischemia, typically seen in toddlers with long-haired mothers, caused by entanglement of hair on the balano-prepucial sulcus, normally associated with circumcision. Its association with hypospadias has been reported only once. A school-aged boy admitted for surgery to treat hypospadias failure was incidentally detected to have PHT and severe hourglass deformity of the penis. Urethral anastomosis and glanuloplasty were done after removal of the constricting ring, without complications. Normal erections were reported during follow up. Treatment may involve urethral reconstruction and penile reimplantation in extreme cases.

Clinical data (age, sex, T-stage, type of flap, and time interval between reconstruction surgery and CT) and post-operative CT findings of flap status (maximum dimension of the flap, intra- or peri-flap fluid collection and intra- or peri-flap air collection, fat infiltration within the flap, fistula to adjacent aerodigestive tract or skin, and enhanced vascular pedicle) were assessed and compared between the two groups. CT findings showed that the following flap anomalies were observed more frequently in the delayed flap failure group than in the flap success group: intra- or peri-flap fluid collection > 4 cm (61.1% vs. 23.8%, p 2 cm (61.1% vs. 2.4%, p < 0.001), and fistula to adjacent aerodigestive tract or skin (44.4% vs. 0%, p < 0.001). The maximum dimension of the flap, fat infiltration within the flap, and enhanced vascular pedicle were not associated with delayed flap failures. A large amount of fluid or air collection and fistula are the CT findings that were associated with delayed flap failures in patients with suspected post-operative complications after head and neck cancer surgery

    The transverse musculocutaneous gracilis (TMG) flap has become a common solution for breast reconstruction. However, the safe skin paddle limits are not yet understood. In this study, we attempted to address this issue based on our experiences with inferior and posterior skin paddle extension. Forty-four breast reconstructions with TMG flaps performed between November 2010 and January 2014 were analyzed retrospectively. For the first 20 cases, the flap skin paddle was extended 3 cm posteriorly to the middle thigh (group 1). For the next 20 flaps (group 2), the posterior tip was limited to this line, whereas more fat was recruited inferiorly. In the four cases of group 3, the skin flap was extended posteriorly with a second vascular pedicle from the profunda artery perforator (PAP) flap. The weights and the dimensions of the flaps, operating durations, and postoperative complications of the entire series were analyzed. Groups 1 and 2 were statistically compared. Flap complications were statistically more frequent in group 1 compared with group 2 (45 vs. 0%, P = 0.0012); 40% posterior flap tip necrosis was observed in group 1. Conversely, donor site complications were statistically more frequent in group 2 than in group 1 (40 vs. 5%, P = 0.019) with 35% inner thigh dehiscence. In the TMG with extended PAP flap group, the operating duration was 77 min longer compared with the rest of the series with no donor site complications. In one case, limited necrosis occurred at the anterior skin tip. Harvesting the posterior portion of the TMG up to the middle of the posterior thigh may lead to partial flap necrosis. Extending subcutaneous fat removal under the inferior skin incision may increase the risk of donor site complications. Adding a second vascular pedicle from the PAP flap may improve posterior TMG tip perfusion at the expense of a longer operation. © 2015 Wiley Periodicals, Inc.

    In breast reconstruction, the free TRAM-flap offers many advantages over the pedicled TRAM-flap. Due to its superior perfusion, the free flap rarely develops necrosis. Shaping of the flap is easier due to the lack of the thick muscle pedicle. Because the rectus muscle is spared, there is minimal donor site morbidity. However, the necessary microvascular anastomoses reduced the acceptance of the free TRAM-flap. During a 13-months period, 51 breast reconstructions were performed in 41 patients, 31 unilateral and ten bilateral. 45 flaps served for delayed reconstruction and six flaps for immediate reconstruction. The operations were performed by two teams working simultaneously. The average operating time was 3.9 hours for unilateral and 6.9 hours for bilateral delayed reconstruction. For immediate reconstruction, 6.2 and 6.3 hours were required for uni- and bilateral procedures, respectively. In 38 flaps, the thoracodorsal vessels served as recipient vessels; 13 flaps were anastomosed to the internal mammary artery and vein. Postoperative complications were observed in 13 patients. Three vessel anastomoses had to be revised. In one flap, a partial necrosis occurred; in two flaps hematoma evacuation was necessary. Two patients suffered from fat necroses at the abdomen and one umbilicus was lost. Skin irritations and seromas at the abdomen occurred in five patients. Pulmonary embolism was diagnosed in one patient three weeks postoperatively. Abdominal hernias or bulging in the epigastric area were not observed up to 15 months after reconstruction. These results reveal a low complication rate for breast reconstruction with the free TRAM-flap. The advantages of this technique as compared to the pedicled technique are discussed.

    Erosion through skin of connecting tubing of an inflatable penile prosthesis (IPP) has not been previously reported. The aim of this study was to present a case of tubing erosion, review the pertinent literature, and discuss the possible causes and management options, including preservation of the device and its components. A 42-year-old male failing to respond to medical treatment for erectile dysfunction underwent insertion of an AMS 700 IPP in 1986. Six years later, a revision was necessary because of a leak in the right cylinder and 4 years after, the pump was replaced. Fourteen years after the original implant, he presented with a portion of the tube connecting the pump to the right cylinder eroding through the skin. There was no infection. The skin area involved was resected and the original pump and tubing were buried in a new scrotal pocket after thorough irrigation. The IPP remained in place, allowing vaginal penetration and without infection for another 11 years. Three years later, it was de-functionalized, converted into a fixed volume device. It eventually was replaced 25 years after originally implanted with a semirigid prosthesis because it did not provide sufficient rigidity and because of concerns about the presence of "screws" detected during pelvic imaging. Mechanical failures in the early IPP models, as illustrated in this case, were expected. However, the long survival of the device is remarkable. Erosion of the connecting tubing through the skin is unique and, under exceptional circumstances, may be managed conservatively without replacing components of the IPP. Clinicians unfamiliar with procedures involving inflatable devices need to be aware of "foreign bodies" visible in radiological examinations in men who have had revisions of an IPP. Morales A.

    Chronic penile lymphedema arises from the abnormal retention of lymphatic fluid in the subcutaneous tissues and may be secondary to local and systemic medical conditions such as sexually transmitted diseases, filariasis, malignancy, local radiotherapy, and surgery. This case report aims to consider compulsive masturbation as a possible cause of chronic penile edema. A 40-year-old man was referred to our institute for behavioral disturbance, including compulsive masturbation. Neuropsychiatric evaluation showed moderate mental retardation, mild dysarthria and limb incoordination, anxiety, depressed mood, and impulse dyscontrol. Brain MRI pointed out diffuse white matter lesions. Urogenital examination revealed an uncircumcised penis with non-tender edema of the shaft and prepuce with areas of lichenification. Since the most common local and systemic causes of edema were excluded, chronic penile edema due to compulsive masturbation was diagnosed and the compulsive behavior treated with an antidepressant and low-dose neuroleptics. Compulsive masturbation should be taken into account when counselling patients with penile edema.

    Full Text Available Aim: The main objective of the study was to describe the use of skin fold advancement flaps (SFAFs and other reconstructive techniques for closure of large skin defects following mammary tumor excision in dogs. Materials and Methods: Twelve dogs underwent reconstruction of large ventral skin defects following mammary tumor excision with wide margins. Skin fold flaps (flank fold flap and elbow fold flap were elevated from the flank and elbow region, respectively, and transposed and sutured onto the large ventral skin defect following mastectomy in all the dogs. In addition to the skin fold flaps, other reconstructive techniques such as undermining, walking sutures, and tension-relieving suture techniques were followed during surgery in the closure of large skin defects without skin tension and compromising limb mobility. The skin flap viability was assessed subjectively by gross observation of the flap such as color, temperature, capillary perfusion, and cosmetic appearance, and scoring (1-4 was done. Tissue samples were collected from a surgical site on days 3, 6, and 12 post-operatively for histopathological evaluation and healing status of the skin flap. Results: All the surgical wounds healed primarily, without any major complications and the skin flap remained healthy throughout the healing process post-operatively. Distal flap necrosis was noticed in one case and necrosis of skin flap between two suture lines was noticed in another case in which the necrotized distal portion healed by secondary intention after 7 days. The mean survival of subdermal plexus flap in the above cases was 98% which was a subjective evaluation based on surface area of the skin defect measured by Image 'J software and the flap dimensions. The average healing of skin flap in days was 14.91±0.86. Conclusion: The SFAFs along with other reconstructive techniques help in the reconstruction of large ventral skin defects following mastectomy in dogs without much

    Lower lip reconstruction requires consideration of esthetic and functional outcome in selecting a surgical procedure, and reconstruction with local tissue is useful. The authors reconstructed full-thickness defects with a unit advancement flap. Reconstruction was performed using this method in 4 patients with lower lip squamous cell carcinoma in whom tumor resection with preservation of the mouth angle was possible. The lower lip resection width was 30 to 45 mm, accounting for 50% to 68% of the entire width of the lower lip. The flap was prepared by lateral extension from above the mental unit and matched with the potential wrinkle line of the lower lip in order to design a unit morphology surrounded by the anterior margin of the depressor labii inferioris muscle. It was elevated as a full-thickness flap composed of the orbicularis oris muscle, skin, and mucosa of the residual lower lip from the bilateral sides, and advanced to the defect. Flap transfer was adjusted by small triangular resection of the skin on the lateral side of the mental unit. The postoperative scar was inconspicuous in all patients and there was no impairment of the mouth opening-closing or articulation functions. This was a relatively simple surgical procedure. A blood supply of the flap was stable, and continuity of the orbicularis oris muscle was reconstructed by transferred the residual lower lip advancement flap from the bilateral sides. The postoperative mouth opening-closing function was sufficient, and dentures could be placed from an early phase in elderly patients. The postoperative scar was consistent with the lip unit morphology, being esthetically superior. This procedure may be applicable for reconstruction of defects approximately 1/3 to 2/3 the width of the lower lip where the mouth angle is preserved.

    The purpose of this study was to determine the effectiveness of topically applied minoxidil in the pharmacological delay phenomenon and to demonstrate the comparable microscopic and macroscopic changes between minoxidil-pretreated flaps and surgically delayed flaps. A modified version of the McFarlane flap was used. Group 1 rats, in which a caudally based dorsal skin flap was raised and sutured back, were the control group. In group II, minoxidil solution was spread over the marked skin flap area for 7 days. On the 7th day, a caudally based dorsal skin flap was elevated and then sutured back. Group III rats underwent a surgical delay procedure alone. On the 7th day after flap elevation, evaluation was done by histologic examination and calculation of the flap survival areas in all groups. The lowest flap survival rate appeared in group I and was statistically different from groups II and III. The mean surviving skin flap area in the minoxidil-pretreated group was significantly larger than that in the control group. After histologic evaluation, moderate angiogenesis was also detected in group II. We also found that surgical delay significantly reduced flap necrosis when compared to the minoxidil pretreatment group. According to our study, minoxidil may be considered an effective vasoactive agent for the stimulation of angiogenesis in rat cutaneous flaps and capable of achieving pharmacological delay and increasing flap survival.

    2017-09-01

    Full Text Available Background It can be difficult to select an appropriate flap for various defects on the hand. Although defects of the hand usually must be covered with a skin flap, some defects require a flap with rich blood supply and adequate additive soft tissue volume. The authors present their experience with the anconeus muscle free flap in the reconstruction of various defects and the release of scar contractures of the hand. Methods Ten patients underwent reconstruction of the finger or release of the first web space using the anconeus muscle free flap from May 1998 to October 2013. Adequate bed preparations with thorough debridement or contracture release were performed. The entire anconeus muscle, located at the elbow superficially, was harvested, with the posterior recurrent interosseous artery as a pedicle. The defects were covered with a uniformly trimmed anconeus muscle free flap. Additional debulking of the flap and skin coverage using a split-thickness skin graft were performed 3 weeks after the first operation. Results The average flap size was 18.7 cm2 (range, 13.5–30 cm2. All flaps survived without significant complications. Vein grafts for overcoming a short pedicle were necessary in 4 cases. Conclusions The anconeus muscle free flap can be considered a reliable reconstructive option for small defects on the hand or contracture release of the web space, because it has relatively consistent anatomy, provides robust blood supply within the same operative field, and leads to no functional loss at the donor site.

    Apprehension about the normal size of penis is a major concern for men. Aim of the present investigation is to estimate the penile length and circumference of Indian males and to compare the results with the data from other countries. Results will help in counseling the patients worried about the penile size and seeking penis enlargement surgery. Penile length in flaccid and stretched conditions and circumference were measured in a group of 301 physically normal men. Erected length and circumference were measured for 93 subjects. Mean flaccid length was found to be 8.21 cm, mean stretched length 10.88 cm and circumference 9.14 cm. Mean erected length was found to be 13.01 cm and erected circumference was 11.46 cm. Penile dimensions are found to be correlated with anthropometric parameters. Insight into the normative data of penile size of Indian males obtained. There are significant differences in the mean penile length and circumference of Indian sample compared to the data reported from other countries. Study need to be continued with a large sample to establish a normative data applicable to the general population.

Results: fifteen patients underwent scrotal reconstruction using the proposed flap. The mean age was 48.9 years (28 to 66. Skin loss estimates in the scrotal region ranged from 60 to 100%. Definitive reconstruction was performed on average 30.6 days (22 to 44 after the initial surgical treatment. The mean surgical time was 76 minutes (65 to 90 to obtain the flaps, bilateral in all cases. Flap size ranged from 10cm to 13cm in the longitudinal direction and 8cm to 10cm in the cross-sectional direction. The complication rate was 26.6% (four cases, related to the occurrence of segmental and partial dehiscence. Conclusion: the superomedial fasciocutaneous flap of thigh is a reliable and versatile option for the reconstruction of open areas in the scrotal region, showing adequate esthetic and functional results.

    Because of the unique characteristics of its integument, the affirmation "replacing like with like" becomes more than evident in the reconstruction of defects of the ultraspecialized plantar skin. But, the paucity of local resources, and especially in the forefoot, transforms this attempt in a very challenging problem. Many techniques, including skin grafts and various types of flaps were used in the management of defects in the forefoot. We present a new useful flap in the reconstruction of skin defects in the forefoot, based on small perforator vessels originating either from the plantar metatarsal arteries or plantar common digital arteries. Starting with June 2011, this flap was performed, as plantar transposition perforator flap, plantar propeller flap, or plantar propeller perforator plus flap, in seven patients with ulcers over the plantar forefoot. During a follow-up of 7 to 17 months (mean, 9.8 months), the local evolution regarding flap integration, pain, relapse, sensitive recovery, donor site, and footwear quality was analyzed. We registered a 100% survival rate of the flaps, with delayed healing in only one case. The gait resumption was possible after 6 weeks in all cases. This new flap, based on small perforator vessels from the plantar metatarsal or common digital arteries, and which provides a good, stable, and sensory recovery, seems to be a promising method in the reconstruction of plantar skin defects over the metatarsal heads.

    Osteoradionecrosis of the olecranon is an unusual pathologic entity, treated best by debridement and wound closure using vascularized tissue. Local skin is often unavailable for flap design and transposition. The radial forearm flap can be isolated on a proximal vascular pedicle and transposed to cover the wound. In the case presented, healing was brisk and complete, allowing early elbow mobilization. Although the donor site is not easily concealed, no functional impairment results from flap elevation and all full-thickness wounds are confined to the involved extremity

    Full Text Available Penile fracture is the disruption of the tunica albuginea with rupture of the corpus cavernosum secondary to blunt trauma to the erect penis. It is an unusual condition, usually underreported. According to the published literature, vigorous vaginal intercourse with women on top position is the most common etiology across the globe including India with Middle Eastern countries being the exception. A total of seven patients of penile fracture presented in emergency in the last 6 months. The etiology was penile manipulation at the time of sexual excitement in six out of seven patients of penile fracture, which was contrary to the literature published except in Middle Eastern countries. All the patients were managed by emergency exploration and repair. Thus, the incidence and etiologies of penile fracture vary according to geographic region, sexual behavior, marital status, and culture.

    Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The aim of this article was to present the management of a case of a penile epidermal inclusion cyst that occurred because of late complications of a penile girth enhancement surgery. A 52-year-old man presented with a painless, slowly growing mass in the penis, which was first noted after a penile girth enhancement surgery 20 years ago. A cystic mobile mass about 2 cm in depth was found surrounding the coronal sulcus. Excision of the mass was performed for diagnosis and treatment. There was no communication with the urethra. The pathological diagnosis was an epidermal inclusion cyst of the penis. A penile epidermal inclusion cyst in adult men is rare. It can develop after an inadequate procedure for penile girth enhancement, and should be treated by complete resection.

    Despite a variety of flap reconstruction options, the ischium remains the most difficult pressure sore site to treat. This article describes the authors' successful surgical procedure for coverage of ischial ulcers using double adipofascial turnover flaps.After debridement, the adipofascial flaps are harvested both cephalad and caudal to the defect. The flaps are then turned over to cover the exposed bone in a manner so as to overlap the 2 flaps. The skin is then closed with sutures in 2 layers. A total of 15 patients with ischial sores were treated using this surgical procedure.The follow-up period ranged from 11 to 159 months, with a mean of 93.6 months. Overall, 86.7% of the flaps (13 of 15) healed primarily. One patient had a recurrent grade II ischial pressure sore again 11 months after the operation. The other 14 patients did not have a recurrence.Treatment of ischial pressure sores with adipofascial turnover flaps provides an easy, minimally invasive procedure, with preservation of future flap options, and a soft-tissue supply sufficient for covering the bony prominence and filling dead space. This technique is a reliable and safe reconstructive modality for the management of minor ischial pressure sores.

    2010-01-01

    Full Text Available Systemic Sclerosis (SSc is a connective tissue disorder featuring vascular alterations and an immunological activation leading to a progressive and widespread fibrosis of several organs such as the skin, lung, gastrointestinal tract, heart, and kidney. Men with SSc are at increased risk of developing erectile dysfunction (ED because of the evolution of early microvascular tissutal damage into corporeal fibrosis. The entity of penile vascular damage in SSc patients has been demonstrated by using Duplex ultrasonography and functional infra-red imaging and it is now clear that this is a true clinical entity invariably occurring irrespective of age and disease duration and constituting the ‘‘sclerodermic penis’’. Once-daily phosphodiesterase type-5 (PDE5 inhibitors improve both sexual function and vascular measures of cavernous arteries by improving surrogate markers of endothelial dysfunction, that is, plasma endothelin-1 and adrenomedullin levels, which may play a potential role in preventing progression of penile fibrosis and ED. Also, the beneficial effect of long-term PDE5i add-on therapy to SSc therapy in the treatment of Raynaud's phenomenon is described.

A stress/strain recovery analysis is then conducted to verify its structural integrity. A one-dimensional beam analysis is also carried out to assist with the construction of the fan diagram...... of the rotor through modification of unsteady aerodynamic loads. Piezoelectric actuators installed inside the blade manipulate the motion of the trailing edge flap. The proposed blade rotates at higher speed and additional structures are included to support the actuators and the flap. This improves the design....... To select the actuator and design the flap actuation region, the flap hinge moment is estimated via a CFD analysis. To obtain the desired flap deflection of ±4°, three actuators are required. The design of the flap actuation region is validated using a test bed with a skin hinge. However, because the skin...

    2015-01-01

    Full Text Available Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

    With respect to skin pedicles (tubular pedicle or direct flap), an estimation of the blood supply is of great importance in making a decision as to when to perform the separation from the original blood supply. This decision is based on empiric observation of the normal time of healing and varies greatly with the site and the concepts of the individual surgery. A number of methods have been proposed for testing the circulation of pedicle skin flaps or tubes, and these methods all seem more complicated and less accurate than the isotope method that is described in this chapter

    1990-01-01

    Two aspects of the inflammatory response to infection--blood flow alteration and leukocyte mobilization--are investigated in the canine model. The elevation of paired musculocutaneous (MC) and random pattern (RP) flaps allowed comparison of healing flaps with significant differences in blood flow (lower in random pattern flaps) and resistance to infection (greater in musculocutaneous flaps). Blood flow changes as determined by radioactive xenon washout were compared in normal skin and distal flap skin both after elevation and following bacterial inoculation. Simultaneous use of In-111 labeled leukocytes allowed determination of leukocyte mobilization and subsequent localization in response to flap infection. Blood flow significantly improved in the musculocutaneous flap in response to infection. Although total leukocyte mobilization in the random pattern flap was greater, the leukocytes in the musculocutaneous flap were localized around the site of bacterial inoculation within the dermis. Differences in the dynamic blood flow and leukocyte mobilization may, in part, explain the greater reliability of musculocutaneous flaps when transposed in the presence of infection

  4. Using skin and fascial sheath of preputial sac; A new technique for surgery for congenital buried penis

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Congenital buried penis (CBP is a rare condition characterized by penis with normal length obscured under penopubic and penoscrotal skin and subcutaneous tissue. Though rare, this condition causes great parental anxiety because of abnormal shape and appearance of penis, dribbling of urine and poor hygiene. Abnormal distal attachment of fundiform ligament on penile shaft, large, redundant preputial sac, and severe paucity of nonpigmented penile skin are important anatomical factors responsible for CBP. We here describe a different approach for degloving of penis and achieving penile skin cover using skin and fascial sheath of preputial sac. This method is simple and easy to learn, teach and reproduce.

    2017-03-01

    Full Text Available Objectives: Following penile prosthesis implantation (PPI, patients may complain of a decrease in visible penis length. A dorsal phalloplasty defines the penopubic junction by tacking pubic skin to the pubis, revealing the base of the penis. This study aimed to evaluate the efficacy of a dorsal phalloplasty in increasing the visible penis length following PPI. Methods: An inflatable penile prosthesis was implanted in 13 patients with severe erectile dysfunction (ED at the Kamal Shaeer Hospital, Cairo, Egypt, from January 2013 to May 2014. During the surgery, nonabsorbable tacking sutures were used to pin the pubic skin to the pubis through the same penoscrotal incision. Intraoperative penis length was measured before and after the dorsal phalloplasty. Overall patient satisfaction was measured on a 5-point rating scale and patients were requested to subjectively compare their postoperative penis length with memories of their penis length before the onset of ED. Results: Intraoperatively, the dorsal phalloplasty increased the visible length of the erect penis by an average of 25.6%. The average length before and after tacking was 10.2 ± 2.9 cm and 13.7 ± 2.8 cm, respectively (P <0.002. Postoperatively, seven patients (53.8% reported a longer penis, five patients (38.5% reported no change in length and one patient (7.7% reported a slightly shorter penis. The mean overall patient satisfaction score was 4.9 ± 0.3. None of the patients developed postoperative complications. Conclusion: A dorsal phalloplasty during PPI is an effective method of increasing visible penis length, therefore minimising the impression of a shorter penis after implantation.

    Full Text Available OBJECTIVE: To investigate the vessel endothelial growth factor (VEGF as a risk factor in squamous cell carcinoma of the penis (SCCP. METHODS: Forty-seven patients with penile carcinoma were evaluated retrospectively. The mean age and standard deviation were 61.1±11.7 years. All of them were treated by penectomy and those with positive nodes underwent groin lymphadenectomy. Tumor grading was 35 G1 and 12 G2/3. Primary lesion stage was 24 pT1 and 23 pT2-4. Positive inguinal nodes were observed in 15 patients. Selected paraffin embedded sections were submitted to VEGF immunohistochemical analysis by the avidin-biotin-immunoperoxidase method with antigen retrieval. All slides were examined using an automatic analyzer system and the proportion of labeled cells in 10 high magnification power fields (400X were recorded in a blind analysis. RESULTS: Median (% labeling index was 2.3 in G1 versus 2.2 in G2/3 tumors (p=0.60, and 4.0 in pT1 versus 1.8 pT2-4 tumors (p=0.10. The respective data for pN0 patients was 2.8 and for pN+ was 2.1 (p=0.20. Survival curves showed no association with patients survival. CONCLUSION: In squamous cell carcinoma of the penis the VEGF immunoexpression has no association with tumor grade or stage, as well as with patient survival.

    Transgender surgeries are becoming more frequent and visual interpretation of anatomy is essential for both surgeons and patients. Since the forearm free flap phalloplasty was introduced in 1984, it has been known to provide reliable cosmetic and functional results for transitioning men compared with phalloplasty by different flaps. Surgical text descriptions were enhanced by the creation of new anatomic illustrations. The forearm free flap consists of the anterior forearm skin, subcutaneous tissue, fascia containing the radial artery as the perforator and its venae comitantes, cephalic and basilic veins, and lateral and medial antebrachial cutaneous nerves are demonstrated in relation to the surgically derived flap. Song's forearm free flap phalloplasty requires two surgical stages with a three-month interval between the stages: prelamination of a neourethra and construction of a neophallus. The neophallus created by forearm flap phalloplasty is reported to achieve acceptable aesthetical and psychological satisfaction, appropriate size and shape, and satisfying sexual intercourse. Despite increasing experiences in gender confirming surgery with modifications made by many authors, urethral complications including fistula and/or stricture formation are the leading causes of reoperation. The poor esthetic outcome of the forearm donor site and a decrease in rigidity of the neophallus are the main limitations. Illustrations of anatomy help inform surgical choice and understanding of risks and benefits by patients. The anatomy of the free forearm flap phalloplasty supports creation of a neophallus for transsexual anatomy revision. Clin.

    84 patients with oral and oropharynx cancer were treated between 1985 and 1993. Radical treatment (surgery with radiotherapy) was applied in 38 patients (45%). In 59 cases (70%) the reconstruction with flaps was necessary. In 31 patients the tongue flap was used, in 18 cases pectoralis major myocutaneous flap was used, in 6 patients pedicle skin flap was used and in 1 case the full-thickness skin graft was applied. The authors believe the tongue flap is good for reconstruction in the early stadium of cancer, and the resection of advanced cancer requires the application of the myocutaneous flap supplied with blood vessels 9 refs, 2 tabs

    Many commissural reconstruction techniques have been described for the treatment of syndactyly. This study is the first to compare long-term results of 2 commissural dorsal flap procedures (T-flap and omega-flap). Fifty-nine web-spaces in 39 patients, operated on between 1991 and 2008, were retrospectively analyzed. Thirty-six T-flap and 23 omega-flap procedures were performed using full-thickness skin graft in every case for digital resurfacing. Factors that could affect the long-term outcome were collected, including development of web-creep, clinodactyly, and flexion contracture. Patients were reviewed with a mean follow-up of 5 years and 8 months. Preoperative complexity of syndactyly influenced the development of clinodactyly and flexion contracture. Among the patients who developed clinodactyly, 96% had surgery for complex syndactyly. No difference was found between the 2 flap methods concerning digital deformation and mobility. However, web-creep occurred more frequently after T-flap than after omega-flap procedures (17% vs. 5%). The combination of either dorsal commissural T-flaps or omega-flaps with full-thickness graft to resurface digits is a reliable technique for the treatment of syndactyly with satisfactory functional and cosmetic results. Long-term results are not influenced by the type of flap. Nevertheless, the omega-flap technique, using 2 triangular lateral-palmar flaps, avoids use of skin graft to cover lateral-palmar aspects of the new commissure, consequently reducing the incidence of web-creep. In cases of syndactyly, the primary prognostic factor is whether the patient has simple or complex syndactyly. In complex syndactyly, the risk of long-term unfavorable results is higher. When complex complicated syndactyly is involved, postoperative complication rates increase. Level III.

    Full Text Available Hand burn scar contractures affect patients in aesthetic and functional aspects. After releasing these scars, the defects should be repaired. The reconstruction methods include primary suturation, Z plasty, skin grafting, local or free flaps, etc. All methods have their own advantages and disadvantages. One of the most useful flaps is the reverse ulnar perforator flap. We performed a two-staged procedure for repairing a post-burn contracture release defect in a 40-year-old male. In the first stage we applied reverse ulnar perforator flap for the hand defect, and ulnar artery and vein repair in the second stage. In conclusion, this two-staged procedure is a non-primary but useful option for hand and finger defects and prevents major vascular structure damage of the forearm.

    Penile revascularization is a surgical treatment option for erectile dysfunction (ED) in healthy individuals due to a focal arterial occlusion in the absence of generalized vascular disease. Most described failures have been attributed to graft stenosis or disruption of the anastomosis. We report a novel phenomenon called Penile Artery Shunt Syndrome that contributed to persistent ED in a patient after penile microvascular arterial bypass surgery. A 26-year-old man presented for evaluation of long-standing ED, which was attributed to trauma sustained 12 years earlier. He had difficulty obtaining and maintaining erections despite oral pharmacotherapy. Clinical data related to the case were studied, analyzed, and reviewed with urologic and radiologic specialists at multiple centers that collaborated in the care of this patient. Penile duplex ultrasound peak systolic velocities and five-item International Index for Erectile Function questionnaire scores were the main outcome measures. Initial diagnostic workup of the patient confirmed severe insufficiency of the left cavernosal artery, with no evidence of venous leak. The patient underwent penile microvascular arterial bypass surgery with anastomosis of the left inferior epigastric artery to the left dorsal penile artery. The patient had persistence of severe ED despite patent anastomosis by penile duplex ultrasound. Subsequent arteriography revealed an arterial shunt due to an aberrant obturator artery arising from the donor inferior epigastric artery. The patient underwent embolization of the aberrant obturator artery, with resolution of the shunt and marked improvement in erectile function. The presence of an aberrant obturator artery arising from the inferior epigastric artery may predispose to persistent ED after revascularization due to the creation of a shunt phenomenon. Pelvic arteriography may be useful in identifying anomalous anatomic considerations prior to penile revascularization and to evaluate patients

    Hereditary renal adysplasia (HRA) is rare autosomal dominant condition. Patients have several other anomalies including Potter facies, thoracic, cardiac, and extremity deformities. The case present dysmorphic facial features such as hypertelorism, prominent epicanthic folds, a flat and broad nose, choanal stenosis, low set ears and a receding chin. He had femoral bowing, hypoplastic right tibia and agenesis of the right foot. He had rich and thin skin. He had also a dysplastic empty scrotum, penile agenesis, and anal atresia. The autopsy revealed pulmonary hypoplasia, ventricular septal defect, bilateral multicystic renal dysplasia, agenesis of ureter and bladder, intraabdominal testicles, and a single umbilical artery. The penile agenesis was first reported, and including the consanguinity in the parents might further delineate the bilateral multicystic HRA. Vater/caudal regression anomalies, Mullerian duct/aplasia, unilateral renal agenesis, and cervicothoracic somite anomalies association and Coloboma, heart anomaly, choanal atresia, retardation, retardation, genital and ear anomalies syndrome has been considered in differential diagnosis.

    Full Text Available PURPOSE: To investigate the effects of different low-level laser therapy (LLLT doses on random skin flap rats. METHODS: Forty Wistar rats were randomly divided in four groups. The control group (CG was not irradiated. The experimental groups were irradiated with a diode laser 670 nm with different energies per point: group 2 (G2 with 0.06 J; group 3 (G3 0.15 J and group 4 (G4 0.57 J. The three groups were irradiated in 12 equally distributed points in the cranial skin flap portion. They were submitted to the irradiation during the immediate, first and second postoperative days. The necrosis area was evaluated in the seventh postoperative day. RESULTS: The CG shows 49.35% of necrosis area in the skin flap; G2, 39.14%; G3, 47.01% and G4, 29.17% respectively. There was a significantly difference when G4 was compared with CG`s skin flap necrosis area. CONCLUSION: The low-level laser therapy diode 670 nm with 0.57 J energy per point increases the survival in randomic skin flap rats.OBJETIVO: Investigar os efeitos de diferentes doses de laserterapia de baixa intensidade na viabilidade de retalhos cutâneos randômicos em ratos.

    2004-01-01

    PIV measurements of the flow in the region of a flap side edge are presented for several flap configurations. The test model is a NACA 63(sub 2)-215 Hicks Mod-B main element airfoil with a half-span Fowler flap. Air is blown from small slots located along the flap side edge on either the top, bottom or side surfaces. The test set up is described and flow measurements for a baseline and three blowing flap configurations are presented. The effects that the flap tip jets have on the structure of the flap side edge flow are discussed for each of the flap configurations tested. The results indicate that blowing air from a slot located along the top surface of the flap greatly weakened the top vortex system and pushed it further off the top surface. Blowing from the bottom flap surface kept the strong side vortex further outboard while blowing from the side surface only strengthened the flap vortex system. It is concluded that blowing from the top or bottom surfaces of the flap may lead to a reduction of flap side edge noise.

    To compare the effectiveness of complex defects repair between using chimeric anterolateral thigh flap and series-wound flaps after resection of oral and maxillofacial cancer. After resection of oral and maxillofacial cancer, defect was repaired with chimeric anterolateral thigh flap in 39 patients between January 2011 and July 2014 (chimeric anterolateral thigh flap group); and defect was repaired with series-wound flaps in 35 patients between January 2009 and December 2010 (series-wound flaps group). There was no significant difference in gender, age, duration of disease, tumor type, tumor staging, defect location, and defect area between 2 groups (P > 0.05). The operation time, flap harvesting and microvascular anastomosis time, stomach tube extraction time, and oral feeding time were recorded and compared between 2 groups, and postoperative complications were observed; the effectiveness was evaluated according to clinical efficacy evaluation table of bone and soft tissue defects reconstruction surgery in oral and maxillofacial region. Vascular crisis occurred in 2 cases of chimeric anterolateral thigh flap group, and 4 cases of series-wound flaps group. Partial necrosis appeared at distal end of a series-wound flaps, and oral fistula and infection developed in 3 series-wound flaps. The other flaps and the grafted skin at donor site survived; wounds at recipient site healed by first intention. The operation time, stomach tube extraction time, and oral feeding time of chimeric anterolateral thigh flap group were significantly shorter than those of series-wound flaps group (P oral closure function, chew, language performance, and swallowing scores of the chimeric anterolateral thigh-flap group were significantly better than those of the series-wound flaps group (P oral cavity holding water test, and occlusion scores between the 2 groups (P > 0.05).

    Soft tissue defects on the lateral borders of the digits are difficult to reconstruct using local or local-regional flaps. We describe a "palmar pivot flap" to resurface an adjacent defect on the palmar-lateral aspect of the digit. The surgical technique is described. This flap is an axial pattern flap based on the subcutaneous transverse branches of the digital artery. The flap is pivoted up to 90 degrees on the neurovascular bundle in its base, into an adjacent defect. The flap can be raised from either the proximal or the middle phalangeal segments. It can cover defects sited from the level of the proximal interphalangeal joint up to the fingertip. The donor defect is limited to the same digit and is covered with a full-thickness skin graft. We have used this flap on 3 patients with defects at the middle phalangeal segment, the distal interphalangeal joint, and the fingertip. All healed primarily. One patient had a mild flexion contracture of the proximal interphalangeal joint, whereas the other 2 had no complications. The patients with distal interphalangeal joint and fingertip defects had excellent sensation in the flap (2-point discrimination of 5-6 mm). The palmar pivot flap is useful for resurfacing otherwise difficult defects on the lateral borders of the digits around and distal to the proximal interphalangeal joint, including those at the fingertip. It provides sensate, glabrous skin. The donor defect is on the same digit and is well hidden, producing an aesthetic and functional reconstruction.

    In penile cancer, the optimal diagnostics and management of metastatic lymph nodes are not clear. Advances in minimally invasive staging, including dynamic sentinel lymph node biopsy, have widened the diagnostic repertoire of the urologist. We aimed to provide an objective update of the recent trends in the management of penile squamous cell carcinoma, and inguinal and pelvic lymph node metastases. We systematically reviewed several medical databases, including the Web of Science® (with MEDLINE®), Embase® and Cochrane databases, according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines. The search terms used were penile cancer, lymph node, sentinel node, minimally invasive, surgery and outcomes, alone and in combination. Articles pertaining to the management of lymph nodes in penile cancer were reviewed, including original research, reviews and clinical guidelines published between 1980 and 2016. Accurate and minimally invasive lymph node staging is of the utmost importance in the surgical management of penile squamous cell carcinoma. In patients with clinically node negative disease, a growing body of evidence supports the use of sentinel lymph node biopsies. Dynamic sentinel lymph node biopsy exposes the patient to minimal risk, and results in superior sensitivity and specificity profiles compared to alternate nodal staging techniques. In the presence of locoregional disease, improvements in inguinal or pelvic lymphadenectomy have reduced morbidity and improved oncologic outcomes. A multimodal approach of chemotherapy and surgery has demonstrated a survival benefit for patients with advanced disease. Recent developments in lymph node management have occurred in penile cancer, such as minimally invasive lymph node diagnosis and intervention strategies. These advances have been met with a degree of controversy in the contemporary literature. Current data suggest that dynamic sentinel lymph node biopsy provides excellent

    We reviewed the results of direct vision urethrotomy for short (less than 1 cm) penile urethral strictures following hypospadias surgery. Patients with less than 1 cm anterior penile urethral strictures located proximal to the meatus underwent direct vision urethrotomy. Based on the type of initial urethroplasty patients were randomly divided into treatment with direct vision urethrotomy vs direct vision urethrotomy plus clean intermittent catheterization for 3 months. Success was defined as absent obstructive voiding symptoms and a normal urine flow 2 years following the last patient instrumentation. Of patients with urethral strictures following hypospadias repair 44% (32) had previously undergone tubularized graft urethroplasty and 56% (40) had previously undergone flap urethroplasty, including a tubularized island flap in 18, an onlay flap in 11 and urethral plate urethroplasty in 11. Direct vision urethrotomy alone was performed in 51% of patients (37), and direct vision urethrotomy and clean intermittent catheterization were performed in 49% (35). Success with the 2 methods was similar, that is 24% (9 of 37 patients) vs 22% (8 of 35). Following direct vision urethrotomy all patients with tubularized graft urethroplasty showed failure (0 of 32). Success was noted in 11% of patients (2 of 18) with tubularized island flap urethroplasty compared to 72% (8 of 11) with onlay urethroplasty and 63% (7 of 11) with urethral plate urethroplasty (each p urethrotomy does not improve the likelihood of success. Direct vision urethrotomy for short (less than 1 cm) urethral stricture usually fails following any type of tubularized graft or flap urethroplasty but it had moderate success following onlay flap and urethral plate urethroplasties.

    Full Text Available BackgroundA thinned anterolateral thigh (ALT flap is often harvested to achieve optimal skin resurfacing. Several techniques have been described to thin an ALT flap including an adipocutaneous flap, an adipofascial flap and delayed debulking.MethodsBy systematically reviewing all of the available literature in English and French, the present manuscript attempts to identify the common surgical indications, complications and donor site morbidity of the adipofascial variant of the ALT flap. The studies were identified by performing a systematic search on Medline, Ovid, EMBASE, the Cochrane Database of Systematic Reviews, Current Contents, PubMed, Google, and Google Scholar.ResultsThe study selection process was adapted from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, and 15 articles were identified using the study inclusion criteria. These articles were then reviewed for author name(s, year of publication, flap dimensions and thickness following defatting, perforator type, type of transfer, complications, thinning technique, number of cases with a particular area of application and donor site morbidity.ConclusionsThe adipofascial variant of the ALT flap provides tissue to fill large defects and improve pliability. Its strong and safe blood supply permits adequate immediate or delayed debulking without vascular complications. The presence of the deep fascia makes it possible to prevent sagging by suspending and fixing the flap for functional reconstructive purposes (e.g., the intraoral cavity. Donor site morbidity is minimal, and thigh deformities can be reduced through immediate direct closure or liposuction and direct closure. A safe blood supply was confirmed by the rate of secondary flap debulking.

    Anatomical variance of the deep circumflex iliac artery is of high clinical value in facial reconstruction using a deep circumflex iliac artery perforator (DCIAP) flap. We present the case of a 76-year-old woman treated with an osteomyocutaneous DCIAP flap variant for facial reconstruction. We also review here the literature on DCIA perforator flaps and the different anatomical variances, which might bring clinical benefits. The observed anatomy in our patient offered the possibility to raise a free flap variant with high mobility of a large skin paddle and a long vascular pedicle combined with a variable osteomuscular portion. The characteristics of the flap thus raised help overcome the disadvantages of the conventional DCIAP flap and offer excellent options for facial reconstruction.

    Microsurgical techniques have developed numerous territories suitable for free tissue transfer. However, the demand for thin cutaneous resurfacing limits the choice of flaps available to the reconstructive microsurgeon. The radial forearm flap is a thin, axial, fasciocutaneous flap, offering pliable cutaneous resurfacing, with or without sensation. We have used 15 flaps to reconstruct defects in the head and neck and lower extremity resulting from burns, blunt and avulsive trauma, radiation necrosis, and tumor ablation. Two flaps (15 percent) developed venous congestion and were salvaged by reoperation. One retrograde flap (7.5 percent) developed partial necrosis from arterial insufficiency. Neural re-innervation was successful in two out of three patients in whom it was attempted. Two patients (15%) sustained minor donor site skin graft loss that healed secondarily. In our series of predominantly older patients the donor sites have been relatively inconspicuous at one year follow-up. A functional restoration was achieved in all patients

    Objectives: To report findings in bone scans for breast cancer patients with mastectomy and breast reconstruction with transverse rectus abdominis myocutaneous flap (TRAM). Material and Methods: Inclusion criteria were: confirmed breast cancer, mastectomy, breast reconstruction with TRAM flap and bone scan performed after TRAM. Exclusion criteria were: Absence of bone scan image, breast reconstruction by other approaches. Results: Absence of uptake in TRAM flap in six patients, diminished uptake in skin near TRAM, with peripheral increased uptake in three and increased uptake in TRAM flap, in a patient with cancer recurrence, confirmed by biopsy. Conclusions: Bone scans in breast cancer patients with mastectomy and TRAM flap can have different imaging presentations, procedure details diminish reporting errors. TRAM flap may present fat necrosis areas, which should be differentiated from recurrence in bone scans. Additional imaging and biopsy will be needed to diagnose this finding. (authors).

    This study explored the feasibility and clinical efficacy of expanded flap to repair facial scar left by radiotherapy of hemangioma. From March 2000 to April 2011, 13 cases of facial cicatrices left by radiotherapy of hemangioma have been treated with implantation surgery of facial skin dilator under local anesthesia. After water flood expansion for 1-2 months, resection of facial scar was performed, and wound repairing with expansion flap transfer was done. Thirteen patients were followed up from 5 months to 3 years. All patients tolerated flap transfer well; no contracture occurred during the facial expansion flap transfer. The incision scar was not obvious, and its color and texture were identical to surrounding skin. In conclusion, the use of expanded flap transfer to repair the facial scar left by radiotherapy of hemangioma is advantageous due to its simplicity, flexibility, and large area of repairing. This method does not affect the subsequent facial appearance.

    Kasandra R. Dassoulas, MD

    2017-09-01

    Full Text Available Summary:. Low-lying rectal cancers are being treated more frequently with robotic-assisted abdominoperineal resection, obviating the need for laparotomy and the ability to raise vertical rectus abdominis musculocutaneous flaps. For female patients, posterior vaginectomy often accompanies the resection. Combined pudendal thigh flaps as an extension of bilateral gluteus advancement flaps allow for posterior vaginal resurfacing with thin pliable fasciocutaneous flaps, which rest on the gluteal flap soft-tissue bulk that obliterates the pelvic dead space. For patients with advanced cancers who have had neoadjuvant chemoradiation, the pudendal skin paddle can be planned more laterally to bring in healthier medial thigh skin. The donor incisions lie within the gluteal cleft and crease and groin creases recapitulating normal perineal anatomy and aesthetics.

    Penile paraffinoma is a well-known delayed complication of paraffin oil injection into the penis for penile girth augmentation but its MRI features have not been previously described. A 35-year-old Ukraine man presented with erectile dysfunction, voiding difficulty and an irregular, hard and painful penile mass that had progressively grown over the last year. He reported having received, seven years before, several penile injections of paraffin oil for penile girth augmentation. On physical examination, the mass was tender, poorly delimited, and involved the whole penile shaft and the cranial part of the scrotum. Preoperative MRI, performed to determine the extent of tissue to be removed and the possibilities of penile reconstruction, showed a newly-formed homogeneous tissue, compressing but not infiltrating Buck’s fascia, iso-hypointense relative to muscle on T1-weighted sequences, and with a low signal intensity at T2-weighted sequences. On T1-weighted fat suppressed sequences, it did not enhance with contrast administration. MRI data were confirmed by surgical findings, as the newly-formed scar tissue did not infiltrate Buck’s fascia. Pathology confirmed the diagnosis of penile paraffinoma. MRI seems to provide an adequate imaging of the histological events occurring after injection of paraffin oil in the subcutaneous tissues. Penile paraffinoma remains a clinical diagnosis, but MRI features may be helpful in planning an adequate surgical strategy and, in selected cases, establishing the differential diagnosis with other penile diseases, including cancer

    The concept of extended thoracodorsal artery perforator (TDAP) flap was described in 2015 for breast reconstruction. Our anatomical study aims to identify the territories vascularised by the thoracodorsal artery perforator via the deep muscular fascial network. The second goal was to define the volume of the extended TDAP flap. Ten extended TDAP flaps were dissected on 5 fresh human cadavers. Around the classical skin paddle of a TDAP flap, the dissections were performed in a subfascial level, including the muscular fascia and the adipose tissue compartments to increase the volume of the flap. After injection of methylene blue in the thoracodorsal artery, we measured the length and width, the surface and the volume of the coloured flap. The mean sizes of the extended TDAP flap were 24.9 cm × 20.1 cm. The mean surface of the total vascularization zone was 441 cm 2 . The mean volume of the vascularized flap was 193 ml. The thoracodorsal artery perforator via the deep muscular fascial network allows us to harvest a flap of 25 cm × 20 cm with a mean surface of 441 cm² and a mean volume of 193 ml. The extended TDAP flap is a credible option in breast reconstruction.

    The authors discuss the indications for homodigital island flap with a reverse vascular pedicle. This flap is based on the anastomoses between the radial and ulnar digital arteries. These anastomotic branches lie between the posterior wall of the tendon sheath and the periosteum to form an arch and are named the "digitopalmar arches". The vascularization of the reverse homodigital island flap is derived by using the middle transverse palmar arch. This flap was performed successfully in 14 patients involving 15 fingers to resurface amputation of the distal phalanx. In 6 cases the flap was used as an "artery" flap, and in 9 cases as a "sensitive" homodigital island flap. The pedicle in these cases was neurovascular also containing the digital nerve. The sensitivity of the flap was obtained by neurorraphy between the transposed digital nerve of the flap and the receiving digital nerve of the recipient finger. This technique achieves cover of the tactile pad in one operative stage and provides well vascularized skin allowing early mobilization. Sensation of the flap can be restored rapidly when neurorraphy of the transposed digital nerve is performed.

    Reconstruction of the perineum is required following oncological resections. Plastic surgical techniques can be used to restore the aesthetics and function of the perineum. The gracilis myocutaneous flap provides a substantial skin paddle, with minimal donor site morbidity. The flap is pedicled on a perforator from the medial circumflex femoral artery, giving it limited reach across the perineum. Tunnelling the flap under the adductor longus muscle may free up more of the arterial pedicle, increasing its reach. On three female cadavers, bilateral gracilis flaps were raised in the standard surgical manner, giving six flaps in total. With the flaps pedicled across the perineum, the distance from the tip of each flap was measured to the anterior superior iliac spine (ASIS). The flaps were then tunnelled under the adductor longus muscle. The distances to the ASIS were measured again. The average pedicle length was greater than 7 cm. Tunnelling the flap under the adductor longus muscle increased the reach by more than 4 cm on average. Cadaveric dissection has shown that tunnelling of the flap in a novel way increase its reach across the perineum. This additional flexibility improves its use clinically and is of benefit to plastic surgeons operating in perineal reconstruction.

    Finding an appropriate soft-tissue grafting material to close a wound located over the dorsum of a finger, especially the distal phalanx, can be a difficult task. The boomerang flap mobilized from the dorsum of the proximal phalanx of an adjacent digit can be useful when applied as an island pedicle skin flap. The vascular supply to the skin flap is derived from the retrograde perfusion of the dorsal digital artery. Mobilization and lengthening of the vascular pedicle are achieved by dividing the distal end of the dorsal metacarpal artery at the bifurcation and incorporating two adjacent dorsal digital arteries into one. The boomerang flap was used in seven individuals with injuries involving the dorsal aspect of the distal phalanx over the past year. Skin defects in all patients were combined with bone,joint, or tendon exposure. The authors found that the flap was reliable and technically simple to design and execute. This one-step procedure preserves the proper palmar digital artery to the fingertip and has proven valuable for the coverage of wide and distal defects because it has the advantages of an extended skin paddle and a lengthened vascular pedicle. When conventional local flaps are inadequate, the boomerang flap should be considered for its reliability and low associated morbidity.

    Techniques that provide a non-invasive method for evaluation of intraoperative skin flap perfusion are currently available but underutilized. We hypothesize that intraoperative vascular imaging can be used to reliably assess skin flap perfusion and elucidate areas of future necrosis by means of a standardized critical perfusion threshold. Five animal groups (negative controls, n=4; positive controls, n=5; chemotherapy group, n=5; radiation group, n=5; chemoradiation group, n=5) underwent pre-flap treatments two weeks prior to undergoing random pattern dorsal fasciocutaneous flaps with a length to width ratio of 2:1 (3 x 1.5 cm). Flap perfusion was assessed via laser-assisted indocyanine green dye angiography and compared to standard clinical assessment for predictive accuracy of flap necrosis. For estimating flap-failure, clinical prediction achieved a sensitivity of 79.3% and a specificity of 90.5%. When average flap perfusion was more than three standard deviations below the average flap perfusion for the negative control group at the time of the flap procedure (144.3+/-17.05 absolute perfusion units), laser-assisted indocyanine green dye angiography achieved a sensitivity of 81.1% and a specificity of 97.3%. When absolute perfusion units were seven standard deviations below the average flap perfusion for the negative control group, specificity of necrosis prediction was 100%. Quantitative absolute perfusion units can improve specificity for intraoperative prediction of viable tissue. Using this strategy, a positive predictive threshold of flap failure can be standardized for clinical use.

    Full Text Available Penile fracture is defined as a traumatic rupture of either corpus cavernosum or the tunica albuginea; sometimes it can be both. It may be caused by exotic masturbation acts, sexual intercourse, or other trauma to this area. This can be accompanied by injury to the urethra, which is the cause of hematuria as a symptom for some patients. Typically, diagnosis of penile rupture or fracture depends on clinical examination and history told by the patients. We are stating the importance of medical imaging in the diagnosis of patients with penile fracture by presenting a case of patient suffered from penile fracture after a fall on his penis where it affected the erection of two-third of his penis. In which, the proper diagnosis by imaging studies and taking actions accordingly can save the patients from unnecessary surgeries that indeed increase the bill of the medical care directly and indirectly. Therefore, most patients can be diagnosed cost-effectively and treated surgically without a need to delay surgery, which is often the case if one was to resort to other investigations. Investigations such as retrograde urethrography for suspected urethral injury should only be used when the diagnosis of penile fracture is in doubt.

    Cervical scar contracture causes both physical and psychological distress for burn patients. Many pedicle flaps or skin grafting have been suggested for reconstruction of cervical scar contracture with variable results in the literature. The authors present the axial thoracic flap based on the thoracic branch of the supraclavicular artery (TBSA) for reconstruction of cervical scar contracture. Postburn scar contractures in anterior neck region of 66 patients had been reconstructed with the axial pattern thoracic flaps based on the TBSA, including 1 expanded and 10 nonexpanded pedicle flaps, and 9 expanded and 46 nonexpanded island pedicle flaps, during 1988 through 2012. After removing and releasing the cervical scar contracture, the flap was designed in the thoracic region. The axial artery of the flap is the TBSA bifurcating from the intersection point of sternocleidomastoid muscle and omohyoid muscle with several concomitant veins as the axial veins. The flap can be designed in a large area within the borders of the anterior border of the trapezius muscle superiorly, the middle part of the deltoid muscle laterally, the midsternal line medially, and the level 3 to 4 cm below nipples inferiorly. After incisions were made along the medial, inferior, and lateral border, dissection was performed toward the pedicle. Donor site was closed directly in expanded cases and with skin grafting in nonexpanded cases. Cervical scar contractures were repaired with good functional and cosmetic results in 64 cases among this cohort. Flap tip necrosis in other 2 cases, caused by postoperative hematoma, was repaired by skin grafting. The color and texture of all flaps were fitted with those of the surrounding skin. The donor sites all healed primarily. The flap sensation in the thoracic region regained in the early stage postoperatively and that in cervical area recovered completely after 6 months according to the report of the patients. With reliable blood supply based on the

    Few clinical retrospective studies have reported the risk factors of pedicled flap necrosis in hand soft tissue reconstruction. The aim of this study was to identify non-technical risk factors associated with pedicled flap perioperative necrosis in hand soft tissue reconstruction via a multivariate logistic regression analysis. For patients with hand soft tissue reconstruction, we carefully reviewed hospital records and identified 163 patients who met the inclusion criteria. The characteristics of these patients, flap transfer procedures and postoperative complications were recorded. Eleven predictors were identified. The correlations between pedicled flap necrosis and risk factors were analysed using a logistic regression model. Of 163 skin flaps, 125 flaps survived completely without any complications. The pedicled flap necrosis rate in hands was 11.04%, which included partial flap necrosis (7.36%) and total flap necrosis (3.68%). Soft tissue defects in fingers were noted in 68.10% of all cases. The logistic regression analysis indicated that the soft tissue defect site (P = 0.046, odds ratio (OR) = 0.079, confidence interval (CI) (0.006, 0.959)), flap size (P = 0.020, OR = 1.024, CI (1.004, 1.045)) and postoperative wound infection (P < 0.001, OR = 17.407, CI (3.821, 79.303)) were statistically significant risk factors for pedicled flap necrosis of the hand. Soft tissue defect site, flap size and postoperative wound infection were risk factors associated with pedicled flap necrosis in hand soft tissue defect reconstruction. © 2017 Royal Australasian College of Surgeons.

    The reconstruction of the posterior trunk remains to be a challenge as defects can be extensive, with deep dead space, and fixation devices exposed. Our goal was to achieve a tension-free closure for complex defects on the posterior trunk. From August 2006 to May 2013, 18 cases were reconstructed with multiple flaps combining perforator(s) and local skin flaps. The reconstructions were performed using freestyle approach. Starting with propeller flap(s) in single or multilobed design and sequentially in conjunction with adjacent random pattern flaps such as fitting puzzle. All defects achieved tensionless primary closure. The final appearance resembled a jigsaw puzzle-like appearance. The average size of defect was 139.6 cm(2) (range, 36-345 cm(2)). A total of 26 perforator flaps were used in addition to 19 random pattern flaps for 18 cases. In all cases, a single perforator was used for each propeller flap. The defect and the donor site all achieved tension-free closure. The reconstruction was 100% successful without flap loss. One case of late infection was noted at 12 months after surgery. Using multiple lobe designed propeller flaps in conjunction with random pattern flaps in a freestyle approach, resembling putting a jigsaw puzzle together, we can achieve a tension-free closure by distributing the tension to multiple flaps, supplying sufficient volume to obliterate dead space, and have reliable vascularity as the flaps do not need to be oversized. This can be a viable approach to reconstruct extensive defects on the posterior trunk. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Romberg disease is an uncommon condition manifested by progressive hemifacial atrophy of the skin, soft tissue, and bone. Facial asymmetry with soft tissue deficiency in Romberg disease causes a significant disability affecting the social life and can bring about many psychological problems. The aim of surgical treatment is cosmetic amelioration of the defect. Several conventional reconstructive procedures have been used for correcting facial asymmetry. They include fat injections, dermal fat grafts, filler injections, cartilage and bone grafts, and pedicled and free flaps. We report our experiences with 11 patients involving 11 free flaps with a minimum 1-year follow-up. All patients were classified as having moderate to severe atrophy. The average age at disease onset was 4.5 years; the average duration of atrophy was 5.2 years. No patients were operated on with a quiescent interval of less than 1 year. The average age at operation was 20.1 years, ranging from 10 to 55 years. Reconstruction was performed using 4 groin dermofat free flaps, 4 latissimus dorsi muscle free flaps, and 3 other perforator flaps. To achieve the finest symmetrical and aesthetic results, several ancillary procedures were performed in 4 patients. These procedures included Le Fort I leveling osteotomy, sagittal split ramus osteotomy, reduction malarplasty and angle plasty, rib and calvarial bone graft, correction of alopecia, and additional fat graft. All patients were satisfied with the results. We believe that a free flap transfer is the requisite treatment modality for severe degree of facial asymmetry in Romberg disease.

    Penile fractures are classically described as presenting with rapid detumescence of an erection associated with blunt trauma. This clinical finding is due to a tear in the tunica albuginea surrounding the corpora cavernosum. In this study, we report and discuss a case of trichotillomania and penile bending impulse resulting in penile fracture, which was operated in the urology clinic. The possible psychological and psychiatric problems underlying the impulsive behavior are discussed, and the ...

    To determine whether adjuvant radiation therapy (RT) is associated with adverse patient-reported outcomes and surgical complications 1 year after skin-sparing mastectomy and immediate autologous free flap reconstruction for breast cancer. We compared 24 domains of patient-reported outcome measures 1 year after autologous reconstruction between patients who received adjuvant RT and those who did not. A total of 125 patients who underwent surgery between 2012 and 2015 at our institution were included from the Mastectomy Reconstruction Outcomes Consortium study database. Adjusted multivariate models were created incorporating RT technical data, age, cancer stage, estrogen receptor, chemotherapy, breast size, body mass index, and income to determine whether RT was associated with outcomes. At 1 year after surgery, European Organisation for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire breast symptoms were significantly greater in 64 patients who received RT (8-point difference on 100-point ordinal scale, PBREAST-Q (Post-operative Reconstruction Module), Patient-Report Outcomes Measurement Information System Profile 29, McGill Pain Questionnaire-Short Form (MPQ-SF) score, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-were not statistically different between groups. Surgical complications were uncommon and did not differ by treatment. RT to the neo-breast compared with no RT following immediate autologous free flap reconstruction for breast cancer is well tolerated at 1 year following surgery despite patients undergoing RT also having a higher cancer stage and more intensive surgical and systemic treatment. Neo-breast symptoms are more common in patients receiving RT by the EORTC Breast Cancer-Specific Quality of Life Questionnaire but not by the BREAST-Q. Patient-reported results at 1 year after surgery suggest RT following immediate autologous free flap breast reconstruction is well tolerated

    Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

    BACKGROUND: Perforator flaps are well established, and their usefulness as freestyle island flaps is recognized. The whereabouts of vascular perforators and classification of perforator flaps in the face are a debated subject, despite several anatomical studies showing similar consistency. In our...... experience using freestyle facial perforator flaps, we have located areas where perforators are consistently found. This study is focused on a particular perforator lateral to the angle of the mouth; the modiolus and the versatile modiolus perforator flap. METHODS: A cohort case series of 14 modiolus...... perforator flap reconstructions in 14 patients and a color Doppler ultrasonography localization of the modiolus perforator in 10 volunteers. RESULTS: All 14 flaps were successfully used to reconstruct the defects involved, and the location of the perforator was at the level of the modiolus as predicted...

    Full Text Available BackgroundThe global prevalence of myelomeningocele has been reported to be 0.8–1 per 1,000 live births. Early closure of the defect is considered to be the standard of care. Various surgical methods have been reported, such as primary skin closure, local skin flaps, musculocutaneous flaps, and skin grafts. The aim of this study was to describe the clinical characteristics of myelomeningocele defects and present the surgical outcomes of recent cases of myelomeningocele at our institution.MethodsPatients who underwent surgical closure of myelomeningocele at our institution from January 2004 to December 2013 were included in this study. A retrospective chart review of their medical records was performed, and comorbidities, defect size, location, surgical procedures, complications, and the final results were analyzed.ResultsA total of 14 patients underwent surgical closure for myelomeningocele defects. Twelve cases were closed with direct skin repair, while two cases required local skin flaps to cover the skin defects. Three cases of infection occurred, requiring incision and either drainage or removal of allogenic materials. One case of partial flap necrosis occurred, requiring secondary revision using a rotational flap and a full-thickness skin graft. Despite these complications, all wounds eventually healed completely.ConclusionsMost myelomeningocele defects can be managed by direct skin repair alone. In cases of large defects, in which direct repair is not possible, local flaps may be used to cover the defect. Complications such as wound dehiscence and partial flap necrosis occurred in this study; however, all such complications were successfully managed with simple ancillary procedures.

    Penile duplication (diphallus) is an extremely rare disorder. It is almost always associated with other malformations like double bladder, exstrophy of the cloacae, imperforate anus, duplication of the rectosigmoid and vertebral deformities. Meanwhile anal canal duplication, the most distal and least common duplication of the digestive tube and is a very rare congenital malformation. A 21 days old Egyptian neonate is reported with complete penile duplication and two scrotums with each one carrying two palpable testes. Both penises have normal shaft with normally located meatus. Clear urine voids from both meati spontaneously. The child had also a fold of redundant skin about 4×5 cm at the anal region in which two separate anal openings are present. In rectal examination we found two normal anuses passing stool spontaneously. Ascending (voiding) cystourethrography revealed two penises with two separate meatuses and one bladder from which the two urethras go out separately. Intravenous pyelogram (IVP) revealed two normal kidneys and ureters. Barium study revealed duplication of rectum and colon, otherwise normal GIT. In our review of the literature, we did not come across any other case of this variety of the penile duplication and congenital presence of two anuses. Unfortunately the patient expired before any surgical correction.

    The aim of this study was to investigate the vascular anatomy of the distal forearm in order to optimize the choice between the radial forearm free flap and the ulnar forearm free flap and to select the best site to harvest the flap. The radial and ulnar arteries of seven fresh cadavers were injected with epoxy resin (Araldite) and the perforating arteries were dissected. The number of clinically relevant perforators from the radial and ulnar arteries was not significantly different in the distal forearm. Most perforators were located in the proximal half of the distal one third, making this part probably the safest location for flap harvest. Close to the wrist, i.e. most distally, there were more perforators on the ulnar side than on the radial side. The ulnar artery stained 77% of the skin surface area of the forearm, showing the ulnar forearm free flap to be more suitable than the radial forearm free flap for the restoration of large defects.

    2013-01-01

    Objective: To describe the management and outcome of patients with penile fracture. Study Design: Case series. Place and Duration of Study: Department of Urology and Renal Transplantation, Jinnah Hospital, Lahore, from March 2008 to March 2011. Methodology: Sixteen patients presenting with clinical findings / history of penile fracture were included in this study. Diagnosis was made on the basis of history and clinical findings. Surgical exploration and repair was done on the same day. In all patients, a subcoronal circumferential degloving incision was made. Rent location and dimensions management and postoperative complication were noted. Postoperatively, erection was suppressed for 4 - 5 days. All patients were discharged with advice of avoidance of sex for about 8 weeks. Patients were followed-upto 6 months. Results: Majority of the patients (87.5%) were married and 13 (81.25%) were aged 18 - 45 years. The typical findings recorded in 100.0% patients were erection at time of fracture, detumescence, swelling and ecchymosis. Audible crackling sound and pain was present in 13 (81.25%) patients. Ten (62.5%) patients had rent in the proximal part of penile shaft and right lateral tear was present in 11 (68.75%) patients. Blood clots were evacuated and closure of rent was done with vicryl 2/0 (interrupted stitches). 100.0% patients had uneventful recovery with only 3 (18.75%) patients developed right chordae of erect penis after treatment. All (100.0%) patients were potent and without any problem of erection. Conclusion: Penile fracture is under-reported. A trauma to erect penis is essential to cause fracture. Surgical exploration and repair is the treatment of choice. (author)

    Full Text Available Pseudoepitheliomatous hyperplasia is an extremely rare condition presenting as a lesion on the glans penis in older men. Physical exam without biopsy cannot differentiate malignant from nonmalignant growth. We report a case of large penile mass in an elderly male with a history of lichen sclerosis, highly suspicious for malignancy. Subsequent surgical removal and biopsy demonstrated pseudoepitheliomatous hyperplasia, an unusual benign histopathologic diagnosis with unclear prognosis.

    Penis lengthening pills, stretch apparatus, vacuum pumps, silicone injections, and lengthening and thickening operations are available for men who worry about their penis size. Surgery is thus far the only proven scientific method for penile enlargement. In this article, we consider patient selection, outcome evaluation, and techniques applied. In our view, sexological counseling and detailed explanation of risks and complications are mandatory before any operative intervention.

    2012-09-01

    Full Text Available Abstract Introduction Penile fracture is an uncommon urologic emergency, and is the traumatic rupture of the tunica albuginea covering the corpus cavernosa. This usually occurs following blunt trauma sustained during coitus, masturbation or self-manipulations to hide or suppress an erection. Clinical diagnosis can often be easily made with typical history and examination findings. However, the patient may present atypically and/or with a suspicion of associated urethral injury. The roles of various diagnostic investigations are being evaluated in these situations. Case presentation We report the case of a 31-year-old African man with penile fracture and suspected associated urethral injury that occurred after self-manipulations to hide an erection. Conclusions Penile ultrasound and sonourethrography provide useful additional diagnostic information to supplement clinical history and physical examination findings and can be performed easily, at low cost and with no delays to surgery.

    2012-04-01

    Full Text Available Phalloplasty procedures for most men requiring penile augmentation surgery are cosmetic procedures; generally the patients have a normal-sized and fully functional penis but they think that their penis is too small. There are not well defined indications for penile enhancement surgery and, except for the treatment of “micropenis”, there are not established guidelines and the outcome measures for success are still unclear. All penile enhancement techniques often do not reach the expected result and the grade of patient’s satisfaction is frequently poor. Phalloplasty procedures for psychological dysmorfism are not approved by any scientific society and the majority of these procedures are performed in private settings. The ethical and medicolegal problems resulting from a penis enhancement can be various and numerous, but few of them are reported in literature. After phalloplasty an attribution of professional responsibility and request of reimbursement is not rare. In this contribution the authors summarize a panorama of several urological and medico-legal aspects related to phalloplasty procedures.

    Mastectomy skin necrosis represents a significant clinical morbidity after immediate breast reconstruction. In addition to aesthetic deformity, necrosis of the native mastectomy skin may require debridement, additional reconstruction, or prolonged wound care and potentially delay oncologic treatment. This study aims to evaluate patient and procedural characteristics to identify predictors of mastectomy skin necrosis after microsurgical breast reconstruction. A retrospective review was performed of all immediate microsurgical breast reconstructions performed at a single academic center. Patient records were queried for age, diabetes, active smoking, previous breast surgery, preoperative radiation, preoperative chemotherapy, body mass index, mastectomy type, mastectomy weight, flap type, autologous flap type, and postoperative mastectomy skin flap necrosis. There were 746 immediate autologous microsurgical flaps performed by three plastic surgeons at our institution during the study period. The incidence of mastectomy skin flap necrosis was 13.4%. Univariate analysis revealed a significantly higher incidence of mastectomy skin necrosis in patients with higher mastectomy weight (P mastectomy type. Multivariate analysis demonstrated statistically significant associations between mastectomy skin necrosis and both increasing mastectomy weight (odds ratio 1.348 per quartile increase, P = 0.009) and diabetes (odds ratio 2.356, P = 0.011). Increasing mastectomy weight and coexisting diabetes are significantly associated with postoperative mastectomy skin necrosis after microsurgical reconstruction. These characteristics should be considered during patient counseling, procedure selection, operative planning, and intraoperative tissue viability assessment. Copyright © 2015 Elsevier Inc.

    Full Text Available El linfedema peneano y escrotal tiene consecuencias funcionales, estéticas, sociales y psicológicas significativas para el paciente que lo padece. Es una enfermedad infrecuente en los países desarrollados, aunque relativamente prevalente en los países tropicales. Su causa más común es la filariasis, aunque en nuestra práctica diaria se asocia más frecuentemente a cirugía, radioterapia, procesos inflamatorios y neoplásicos. Presentamos un caso singular de linfedema penoescrotal secundario a cirugía por hernia inguinal gigante bilateral que persistía un año después de la intervención. El tratamiento quirúrgico consistió en la exéresis de toda la piel linfedematosa del escroto involucrada y el uso de colgajos de piel escrotal posterior para la cobertura testicular. En un segundo tiempo quirúrgico se llevó a cabo una extirpación total de la piel del pene y del tejido subcutáneo superficial a la fascia de Buck. Empleamos injertos de piel de grosor parcial para cubrir el pene denudado. El resultado estético postoperatorio fue aceptable y los resultados funcionales y psicológicos son satisfactorios para el paciente 3 años después de la cirugía.Lymphedema of the penis and scrotum has important functional, cosmetic, social, psychological consequences for the affected patient. It is a rare disease in the developed countries, although it is relatively frequent in tropical countries.

    Full Text Available Background. Alar rim defects are mostly acquired, resulting from burns, traumas or tumor excision. Sometimes they can accompany craniofacial clefts. However, isolated congenital alar defects are extremely rare. Case report. We presented two cases of congenital isolated alar cleft. The defect was closed by the use of an advancement flap, the technique described by Denonvilliers. We achieved both symmetry and appropriate thickness of the nostrils. Skin color and texture of the alar rim were excellent, with scars not excessively visible. Conclusion. Denonvilliers' z-plasty technique by using advancement flap provides both functionally and aesthetically satisfying outcome in patients with congenital alar rim defects.

    2013-09-01

    Studies have focused on enhancing flap viability using superoxide dismutase (SOD), but only a few used SOD from human origin, and most gave the compound systemically. We evaluated the ability of SOD to improve random skin flap survival using human recombinant copper-zinc superoxide dismutase (Hr-CuZnSOD) in variable doses, injected intradermally into the flap. Seventy male Sprague Dawley rats were randomly assigned into 4 groups. Cephalic random pattern flaps were elevated on their backs and intradermal injections of different dosages of Hr-CuZnSOD were given 15 minutes before surgery. Flap survival was evaluated by fluorescein fluorescence. Analysis of variance (ANOVA) and t test statistical analyses were performed. Flap survival in all treated groups was significantly better than in the controls. The beneficial effect of HR-CuZnSOD on flap survival is attained when it is given intradermally into the flap tissue. Theoretically, Hr-CuZnSOD delivered with local anesthetics used in flap elevation may be a valuable clinical tool. Copyright © 2012 Wiley Periodicals, Inc.

    Objective of this study was to assess the feasibility and results of preputial reconstruction and tubularized incised plate urethroplasty (TIP) in patients of proximal hypospadias with ventral penile curvature. Twenty-seven patients of proximal hypospadias who underwent preputioplasty with TIP were evaluated retrospectively. Ventral curvature was corrected by mobilization of the urethral plate with the corpus spongiosum and the proximal urethra; dorsal plication was added according to the severity of curvature. Feasibility of preputial reconstruction was assessed by applying 3 stay sutures-the first to fix the skin at the corona, the second at the junction of the inner and outer preputial skin for pulling up the skin over the glans, and the third stay on penile skin at the level of the corona for retracting the skin. Preputial reconstruction consisted of a standard 3 layered re-approximation of the margins of the dorsal hood. Age of the patients varied from 10 months to 21 years with an average of 6 years and 4 months. Ventral curvature (mild 10, moderate 13, and severe 4 cases) was corrected by the mobilization of the urethral plate and spongiosum in 14 patients, 11 cases had mobilization of the proximal urethra in addition and 2 patients required single stitch dorsal plication with the above-mentioned steps. Two patients developed urethral fistula and 1 had preputial dehiscence. Preputioplasty with TIP is feasible in proximal hypospadias with curvature without increasing the complication rate. Postoperative phimosis can be prevented by on-table testing of the adequacy of preputial skin by 3 stay sutures.

    Full Text Available Blazed up Herpes zoster lesions have been described in very few patients after free and pedicled flap transfer for reconstructive purpose. Although sensory recovery after flap reconstructions has been studied extensively most studies addressed subjective perceptions of sensation. Objective investigations of spontaneous reinervation of free and pedicled flaps are rare. We would like to present a witnessed herpes zoster infection of a latissimus dorsi skin flap 2 years after breast reconstruction.

    We present a cadaveric dissection study to investigate the anatomic feasibility of penile transplantation. Seventeen male cadavers were dissected to reveal detailed anatomy of the dorsal neurovascular structures including dorsal arteries, superficial and deep dorsal veins, and dorsal nerves of the penis. Dorsal artery diameters showed a significant decrease from proximal to distal shaft. Dominance was observed in one side. Deep dorsal vein showed a straight course and less decrease in diameter compared to artery. Dorsal nerves showed proximal branching pattern. In a possible penile transplantation, level of harvest should be determined according to the patient and the defect, where a transgender patient will receive a total allograft and a male patient with a proximal penile defect will receive a partial shaft allograft. We designed an algorithm for different levels of penile defect and described the technique for harvest of partial and total penile transplants.

    2014-02-01

    Full Text Available A 77-year-old woman presented with a 1-year history of a right medial canthal tumor, which was histopathologically diagnosed as a basal cell carcinoma. After removal of the tumor with a 4-mm safety margin, the defect occupied the areas superior and inferior to the medial canthal tendon. We first reconstructed the lower part of the defect using a nasolabial V-Y advancement flap to make an elliptic defect in the upper part. We then created a glabellar subcutaneous pedicled flap to match the residual upper elliptic defect with the major axis set along a relaxed skin tension line. The pedicled glabellar flap was passed through a subcutaneous tunnel to the upper residual defect. At 6 months postoperatively, the patient showed no tumor recurrence and a good cosmetic outcome.

    Full Text Available Context: A variety of nonvenereal diseases can affect the penis and diminish quality of life. Many present similar clinical features and a cutaneous biopsy may be necessary to clarify the diagnosis. Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period. Materials and Methods: A retrospective study was conducted. We reviewed all penile biopsies performed between January 1, 2007 and December 31, 2015 and studied the causes of the nonvenereal penile dermatoses. Results: The sample included a total of 108 patients, aged 62.9 (±17.8 years, between 16 years and 96 years of age. Eighteen dermatoses were identified. Inflammatory diseases were present in 65. 7% of patients (71/108 and neoplastic dermatoses in 34. 3% (37/108. Concerning inflammatory dermatoses, the most frequent were Zoon balanitis (27.8%, 30/108, followed by lichen sclerosus (15.7%, 17/108, psoriasis (11.1%, 12/108, and lichen planus (4.6%, 5/108. In patients with psoriasis, 10 had lesions only in the penis, similarly to all patients with lichen planus. The most frequent malignant tumor was squamous cell carcinoma (SCC (15.7%, 17/108. The most common in-situ tumor was erythroplasia of Queyrat (8.3%, 9/108. A case of basal cell carcinoma (BCC was found. Kaposi sarcoma and mycosis fungoides on penis were also diagnosed, as an additional form of presentation to their generalized disease. Conclusions: In this study, inflammatory diseases were the most frequently diagnosed dermatoses, while SCC was the most common malignant tumor found. In the majority of psoriasis and lichen planus cases, clinical lesions were only present in the genital area.

  20. Experience with peroneus brevis muscle flaps for reconstruction of distal leg and ankle defects

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Objective: Peroneus brevis is a muscle in the leg which is expendable without much functional deficit. The objective of this study was to find out its usefulness in coverage of the defects of the lower leg and ankle. Patients and Methods: A retrospective analysis of the use of 39 pedicled peroneus brevis muscle flaps used for coverage of defects of the lower leg and ankle between November 2010 and December 2012 was carried out. The flaps were proximally based for defects of the lower third of the leg in 12 patients and distally based for reconstruction of defects of the ankle in 26 patients, with one patient having flaps on both ankles. Results: Partial flap loss in critical areas was found in four patients requiring further flap cover and in non-critical areas in two patients, which were managed with a skin graft. Three of the four critical losses occurred when we used it for covering defects over the medial malleolus. There was no complete flap loss in any of the patients. Conclusion: This flap has a unique vascular pattern and fails to fit into the classification of the vasculature of muscles by Mathes and Nahai. The unusual feature is an axial vessel system running down the deep aspect of the muscle and linking the perforators from the peroneal artery and anterior tibial artery, which allows it to be raised proximally or distally on a single perforator. The flap is simple to raise and safe for the reconstruction of small-to moderate-sized skin defects of the distal third of the tibia and all parts of the ankle except the medial malleolus, which is too far from the pedicle of the distally based flap. The donor site can be closed primarily to provide a linear scar. The muscle flap thins with time to provide a good result aesthetically at the primary defect.

    Purpose: To report results for 49 men with squamous cell carcinoma (SCC) of the penis treated with primary penile interstitial brachytherapy at one of two institutions: the Ottawa Regional Cancer Center, Ottawa, and the Princess Margaret Hospital, Toronto, Ontario, Canada. Methods and Materials: From September 1989 to September 2003, 49 men (mean age, 58 years; range, 22-93 years) had brachytherapy for penile SCC. Fifty-one percent of tumors were T1, 33% T2, and 8% T3; 4% were in situ and 4% Tx. Grade was well differentiated in 31%, moderate in 45%, and poor in 2%; grade was unspecified for 20%. One tumor was verrucous. All tumors in Toronto had pulsed dose rate (PDR) brachytherapy (n = 23), whereas those in Ottawa had either Iridium wire (n 22) or seeds (n = 4). Four patients had a single plane implant with a plastic tube technique, and all others had a volume implant with predrilled acrylic templates and two or three parallel planes of needles (median, six needles). Mean needle spacing was 13.5 mm (range, 10-18 mm), mean dose rate was 65 cGy/h (range, 33-160 cGy/h), and mean duration was 98.8 h (range, 36-188 h). Dose rates for PDR brachytherapy were 50-61.2 cGy/h, with no correction in total dose, which was 60 Gy in all cases. Results: Median follow-up was 33.4 months (range, 4-140 months). At 5 years, actuarial overall survival was 78.3% and cause-specific survival 90.0%. Four men died of penile cancer, and 6 died of other causes with no evidence of recurrence. The cumulative incidence rate for never having experienced any type of failure at 5 years was 64.4% and for local failure was 85.3%. All 5 patients with local failure were successfully salvaged by surgery; 2 other men required penectomy for necrosis. The soft tissue necrosis rate was 16% and the urethral stenosis rate 12%. Of 8 men with regional failure, 5 were salvaged by lymph node dissection with or without external radiation. All 4 men with distant failure died of disease. Of 49 men, 42 had an intact

  2. Ipsilateral fasciocutaneous flaps for leg and foot defects

    2003-01-01

    Full Text Available It was a revolutionary enhancement for lower limb reconstruction when fasciocutaneous flaps were first described and used in clinical practice in 1981. Subsequently persistent studies were made to emphasize and confirm the rich vascular network associated with deep fascia. Thereafter studies were directed to identify the various types of perforators supplying the deep fascia and the overlying subcutaneous tissue and skin. Accordingly the scientists classified these flaps keeping in mind their clinical applications. The authors of this article have also performed extensive research on various aspects. This has led to better understanding about the finer details of vascularity. Based on this various modifications have been made for safe application of reconstruction for defects extending from knee to sole. To avoid complications the clinician should be able to select the proper procedure as regards the donor site and the possible preoperative and postoperative technical faults. A well-designed and meticulously executed flap usually has smooth recovery. Both Colour Doppler and Audio Doppler are useful tools in planning a safe flap. Now these flaps have proved to be standard technique without requiring a special set up extensive training.

    It has been suggested that the application of penile-extender devices increases penile length and circumference. However, there are a few scientific studies in this field. The aim of this study was to assess the efficacy of a penile-extender (Golden Erect(®) , Ronas Tajhiz Teb, Tehran, Iran) in increasing penile size. This prospective study was performed on subjects complaining about "short penis" who were presented to our clinic between September 15, 2008 and December 15, 2008. After measuring the penile length in flaccid and stretched forms and penile circumference, patients were instructed to wear Golden Erect(®) , 4-6 hours per day during the first 2 weeks and then 9 hours per day until the end of the third month. The subjects were also trained how to increase the force of the device during determined intervals. The patients were visited at the end of the first and third months, and penile length and circumference were measured and compared with baseline. The primary end point of the study was changes in flaccid and stretched penile lengths compared with the baseline size during the 3 months follow-up. Twenty-three cases with a mean age of 26.5 ± 8.1 years entered the study. The mean flaccid penile length increased from 8.8 ± 1.2 cm to 10.1 ± 1.2 cm and 10.5 ± 1.2 cm, respectively, in the first and third months of follow-up, which was statistically significant (P penis (9.3 ± 0.86 cm vs. 8.8 ± 0.66 cm, P penis girth enhancement using penile extender.

    2014-11-01

    To assess if the bench model fidelity interferes in the acquisition of rhomboid flap skills by medical students. Sixty novice medical students were randomly assigned to 5 practice conditions with instructor-directed Limberg rhomboid flap skills training: didactic materials (control group 1), low-fidelity rubberized line (group 2) or ethylene-vinyl acetate (group 3) bench models; high-fidelity chicken leg skin (group 4) or pig foot skin (group 5) bench models. Pretests and posttests were applied, and Global Rating Scale, effect size, and self-perceived confidence were used to evaluate all flap performances. Medical students from groups 2 to 5 showed better flap performances based on the Global Rating Scale (all P 0.05). The magnitude of the effect was considered large (>0.80) in all measurements. There was acquisition of rhomboid flap skills regardless of bench model fidelity.

    To describe the versatility of the axial pattern flap based on the cutaneous perforating branch of the angularis oris artery for reconstruction of large facial defects in dogs, including complications and clinical outcomes. Retrospective clinical case series. Client-owned dogs (n = 8). Facial flaps (n = 9) based at the commissure of the lip with a caudodorsal orientation were utilized, with established anatomical borders. Flaps were elevated deep to the panniculus carnosus in a caudal to rostral direction, preserving the angularis oris artery, its cutaneous perforator, and surrounding cutaneous vasculature. Flaps were rotated dorsally or ventrally to cover the defect. Primary closure of the donor site was by direct apposition in all cases. Angularis oris axial pattern flaps were most commonly used to close large defects of the nasomaxillary area rostral to the eyes (6 dogs), followed by orbital (2) and intermandibular (1) defects. Defects occurred because of tumor resection (6 dogs), trauma (2), and a chronic, non-healing wounding (1). All flaps healed with acceptable functional and cosmetic outcomes without major complications. Followup ranged from 10 days to 16 months. Minor postoperative complications included flap edema (8 dogs), partial incisional dehiscence (3), distal tip necrosis (2), and oroantral fistula recurrence (1). Angularis oris axial pattern flaps provided hirsute, full-thickness skin coverage of a variety of large facial defects with minor complications, and should be considered when restructuring large defects of the rostral face or chin. © Copyright 2015 by The American College of Veterinary Surgeons.

    To provide an alternative choice for covering trochanteric pressure sores, we report on a modified pedicle anterolateral thigh (ALT) myocutaneous flap based on the descending branch of the lateral circumflex femoral artery. From August 2007 to January 2010, 20 consecutive patients (10 men and 10 women) underwent 21 pedicled ALT myocutaneous flaps for reconstruction of trochanteric pressure sores. The flap was designed and elevated, resembling the ALT perforator flap including part of the vastus lateralis muscle but without skeletonisation of the perforators. The mean age of patients was 79.4 years (range: 46-103). The mean follow-up period was 13.9 months (range: 3-32). The flaps were 8-21 cm long and 5-11 cm wide. All flaps healed without major complications. All donor sites were closed primarily without skin grafting and showed good aesthetic results. No recurrence was observed. This modified design of pedicled ALT myocutaneous flap without skeletonisation of perforators is a reliable and easily harvested flap for reconstruction of trochanteric pressure sores with limited morbidity.

    To explore the clinical effect of the lobulated medial sural artery perforator flap in repairing soft tissue defect in hand or foot. Since March 2012 to September 2014, 6 cases with soft tissue defects in hands or feet were treated by lobulated medial sural artery flaps pedicled with 1st musculo-cutaneous perforator and 2st musculo-cutaneous perforator of the medial sural artery. The size of the flaps ranged from 4.5 cm x 10.0 cm to 6.0 cm x 17.0 cm. 5 cases of lobulated flap survived smoothly, only 1 lobulated flap had venous articulo, but this flap also survived after the articulo was removed by vascular exploration. All flaps had desirable appearance and sensation and the two-point discrimination was 6 mm in mean with 4 to 12 months follow-up (average, 7 months). Linear scar was left in donor sites in 3 cases and skin scar in 3 cases. There was no malfunction in donor sites. Lobulated medial sural artery perforator flap is feasible and ideal method for the treatment of soft tissue defect in hand or foot with satisfactory effect.

    We developed a new surgical model of penile girth enhancement in dog, with minimal damage, fewer complications, and high success rate, to enable the experimental investigation of penile implants. We obtained materials for penile girth enhancement by processing the pericardium and blood vessel wall collected from pigs. Incisions were made at the penile bulb for the implantation of the materials, and facilitate observation and data collection, based on the anatomical features of dog's penis. We measured the girth of the flaccid penis before and after the operation, and erectile function at 1-month postoperation. In addition to evaluation of recovery from the incision and local pathological changes, ultrasonic examination was performed to monitor the long-term changes associated with implantation. The mean girth of the flaccid penis significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm postoperation. Dogs resumed normal mating at 1 month after the operation, without any significant change in the mating time. Ultrasonic examination clearly illustrated the implants, and helped in the measurement of the distance between the materials and the baculum. Chinese Rural dog is a promising animal model for penile girth enhancement surgery. The findings demonstrated that surgical implantation into penile bulb was associated with less damage, faster postoperative recovery, and higher success. For the first time, ultrasonic examination provided objective data on the surgical outcomes of penile girth enhancement.

    Injury to the penis may result from penetrating or nonpenetrating trauma. Nonpenetrating injury to the erect penis can produce albugineal tear, intracavernous hematoma or extraalbugineal hematoma from rupture of the dorsal vessels. Nonpenetrating injury to the flaccid penis usually follows blunt perineal traumas producing extratunical or cavernosal haematomas, or cavernosal artery tear followed by high flow priapism. Differential diagnosis between albugineal tear and other penile injuries must be obtained as soon as possible, since early surgical repair of albugineal tear reduces significantly the rate of postraumatic curvature and fibrosis. Ultrasonography (US) is able to detect the exact site of the tear in most patients as an interruption of the thin echogenic line of the tunica albuginea. Other imaging techniques are rarely required in the clinical practice. Color Doppler US is the imaging modality of choice to evaluate patients with high flow priapism. Focal or diffuse cavernosal fibrosis can be identified with US as echogenic areas in the cavernosal bodies. Postraumatic erectile dysfunction can result from fibrotic changes, nerve and vascular impairment or both. Doppler evaluation of penile vasculature is required in young patients with postraumatic impotence before surgical revascularization procedures. (orig.)

    Full Text Available Due to the lack of skin elasticity defects of the distal hind limb can be a challenge to close. This article assesses a well-described, but completely under-used technique for closure of wounds on the distal tarsus. The technique was used with good success in six cases presenting to the Bryanston Veterinary Hospital with a wide range of underlying pathology ranging from trauma to neoplastic disease of the tarsus. All six cases were treated with a reverse saphenous conduit flap and two of them underwent radiation therapy with no adverse side effects. All cases showed excellent results with a very low degree of flap necrosis that never exceeded 15% of the total flap area. This skin flap provides an excellent treatment method that is reliable in closure of defects of the distal tarsus with few adverse effects. To the author’s knowledge there has been only one previously published report on the clinical use of this type of skin flap,even though the flap is well described in most texts.

    We have previously reported a small series on the closure of large myelomeningocele (MMC) defects with a keystone design perforator island flap (KDPIF) in a paediatric neurosurgical centre in Australia. We are now presenting an updated longer term follow-up of an expanded series demonstrating longer term durability of this vascularized flap for large myelomeningocele defects. The prospective data from the Monash Neurosurgical Database were used to select all cases of MMC between December 2008 and September 2016. Retrospective analysis of the neurosurgical database revealed an additional three patients who underwent KDPIF closure at the Monash Medical Centre for MMC repair at birth. Wound healing was satisfactory in all six cases. With delayed follow-up, there was no associated skin flap separation, skin flap dehiscence, skin flap necrosis, cerebro-spinal fluid leak, however two infections were encountered, both resolved with conservative management including antibiotics and simple washout. In this expanded case series with increased longevity of follow-up, the keystone design perforator island flap remains a robust alternative for closure of large myelomeningocele defects.

    The relation between sexual orientation and penile dimensions in a large sample of men was studied. Subjects were 5122 men interviewed by the Kinsey Institute for Research in Sex, Gender, and Reproduction from 1938 to 1963. They were dichotomously classified as either homosexual (n = 935) or heterosexual (n = 4187). Penile dimensions were assessed using five measures of penile length and circumference from Kinsey's original protocol. On all five measures, homosexual men reported larger penises than did heterosexual men. Explanations for these differences are discussed, including the possibility that these findings provide additional evidence that variations in prenatal hormonal levels (or other biological mechanisms affecting reproductive structures) affect sexual orientation development.

    Diphallus (penile duplication) is very rare and seen once every 5.5 million births. It can be isolated, but is usually accompanied by other congenital anomalies. Previous studies have reported many concurrent anomalies, such as bladder extrophy, cloacal extrophy, duplicated bladder, scrotal abnormalities, hypospadias, separated symphysis pubis, intestinal anomalies and imperforate anus; no penile duplication case accompanied by omphalocele has been reported. We present the surgical management of a patient with multiple anomalies, including complete penile duplication, hypo-gastric omphalocele and extrophic rectal duplication.

    A review of the current state of knowledge is made on sonographic evaluation of penile in patients with erectile dysfunction. This sonography is developed with high resolution ultrasound on gray scale, combined with color Doppler ultrasonography; which the arteries of penile are examined before and during the erection. The penile ultrasonography has meant an important tool in the evaluation of specific patients who have submitted erectile dysfunction, particularly, in those with record of trauma and history of Peyronie's disease. In addition, through a sonographic evaluation has permitted to prove manifestations of the pathophysiological phenomena of the patient in order to establish their classification and guide their treatment [es

    Full Text Available Although a rare occurrence, this event may occur as a result of self-mutilation among individuals with psychiatric disturbances or due to work-related accidents, iatrogenic injuries or the actions of individuals motivated by jealously, rage and feelings of betrayal. In western societies, most penile amputations are the result of self-aggression during a psychotic episode, the treatment of victims involves resuscitation, stabilization and immediate psychiatric support. The amputated tissue must be preserved under hypothermic conditions. Micro-surgery is currently the most widely employed method for penile replantation. This paper describes a successful case of penile replantation following 5 hours of warm ischemia.

    Since their introduction in 1991, propeller flaps are increasingly used as a surgical approach to loss of substance. The aim of this study was to evaluate the indications and to verify the outcomes and the complication rates using this reconstructing technique through a literature review. A search on PubMed was performed using "propeller flap", "fasciocutaneous flap", "local flap" or "pedicled flap" as key words. We selected clinical studies using propeller flaps as a reconstructing technique. We found 119 studies from 1991 to 2015. Overall, 1,315 propeller flaps were reported in 1,242 patients. Most frequent indications included loss of substance following tumor excision, repair of trauma-induced injuries, burn scar contractures, pressure sores and chronic infections. Complications were observed in 281/1242 patients (22.6%) occurring more frequently in the lower limbs (31.8%). Partial flap necrosis and venous congestion were the most frequent complications. The complications' rate was significantly higher in infants (70 years old) but there was not a significant difference between the sexes. Trend of complication rate has not improved during the last years. Propeller flaps showed a great success rate with low morbidity, quick recovery, good aesthetic outcomes and reduced cost. The quality and volume of the transferred soft tissue, the scar orientation and the possibility of direct donor site closure should be considered in order to avoid complications. Indications for propeller flaps are small- or medium-sized defects located in a well-vascularized area with healthy surrounding tissues.

    Full Text Available Background. Reconstruction of intrapelvic defects can be a challenging problem in patients with limited regional muscle flap options and previously resected omentum. In such situations, alternative methods of mobilizing vascularized tissue may be required. Methods. A case of a patient that underwent pelvic extirpation for recurrent rectal cancer who had limited donor sites for flap reconstruction is presented. The mucosa was removed from a blind loop of colon, and a pedicled seromuscular flap based on the colonic mesentery was placed into the pelvis for vascularized soft-tissue coverage and elimination of dead space. Results. The postoperative course was only complicated by a small subcutaneous fluid collection beneath the sacrectomy skin incision, which was drained with radiological assistance. The patient recovered without any major postoperative complications. Conclusion. Seromuscular colonic flap is a useful option for soft-tissue coverage after pelvic extirpation and should be considered by plastic surgeons when other reconstruction options are not available.

    To evaluate the changing cavernosal length of patients with diabetes mellitus (DM) and organic erectile dysfunction (ED) who were treated with inflatable, three-piece penile prostheses, a current surgical treatment option in our clinic, over the course of 12 years. Between April 2000 and December 2012, we retrospectively investigated data from patients who were diagnosed with organic ED and undergone penile prosthesis implantation (PPI). Of the 239 patients, 235 of them were included in the study. Four patients who were operated on for trans-sexuality were excluded from the study. All patients were divided into two groups as those with (Group 1) or without DM (Group 2). Data, including age, body mass index (BMI) in kg/m(2), surgical history, comorbidities, International Index of Erectile Function (IIEF) questionnaire scores, combined intracavernous injection and stimulation (CIS) test results, length of corpus cavernosum while implanting the penile prosthesis, complications, operative times, mean hospital stay, and satisfaction of the patient and partner, were recorded. Kruskal-Wallis and Mann-Whitney U tests were used for statistical analysis. A p-value of 0.05). The length of the corpus cavernosum and the destruction of cavernosal tissues do not depend only on DM. We conclude that these features may have multifactorial causes.

    Surgical excision of tumors from the face may create a defect that is difficult to restore. Skin grafts can only cover superficial defects and has a natural tendency to contract and may not take properly. Also, because of the colour mismatch, it is not cosmetically identical to the face. The use of regional flaps such as the median forehead flaps are usually bulky, can not cover a wide range of facial reconstruction and usually require the donor area to be grafted. The naso-labial flaps are very useful and versatile local flaps, with robust vascularity that can be readily elevated without a delay. The flap can be superiorly based to reconstruct defects on the cheek, side wall or the dorsum of the nose, alae, collumula and the lower eye lid. Inferiorly based flaps can be used to reconstruct defects in the upper lip, anterior floor of the mouth and the lower lip. The flap can be turned over and used as a lining of the nose and the lip. Aim of the Study: In the current study we present our experience with utilization of the nasolabial flaps in facial reconstruction. We evaluated the indications, flap designs, technique, and complications. We will also assess the final functional and aesthetic results. Material and Methods: The study included 20 patients (12 males and 8 females) presented at the surgical department, National Cancer Institute (NCl) Cairo University with skin cancer at different areas of the face. Preoperative assessment includes. Assessment of the stage of the disease, the flap design and patient general condition. The mean age of the patients was 56.3±6 years (range ]6-62 years). Fifteen patients presented with basal cell carcinoma, 2 squamous cell carcinoma, one malignant melanoma, one keratoacanthoma, and one xeroderma pigmentosa. Nasal defects constituted 75% of cases, the rest were lower eye lid (2), one upper lip and one oral commisure beside a case of cheek reconstruction. There was no major complication; only one patient suffered a reactionary

    A conventional rotor control system restricted at 1/rev frequency component is unable to vary the hub vibratory loads and the aero acoustic noise, which exist in high frequency components. Various active rotor control methodologies have been examined in the literature to alleviate the problem of excessive hub vibratory loads and noise. The active control device manipulates the blade pitch angle with arbitrary higher harmonic frequencies individually. In this paper, an active trailing-edge flap blade, which is one of the active control methods, is developed to reduce vibratory loads and noise of the rotor through modification of unsteady aerodynamic loads. Piezoelectric actuators installed inside the blade manipulate the motion of the trailing edge flap. The proposed blade rotates at higher speed and additional structures are included to support the actuators and the flap. This improves the design, as the blade is able to withstand increased centrifugal force. The cross-section of the active blade is designed first. A stress/strain recovery analysis is then conducted to verify its structural integrity. A one-dimensional beam analysis is also carried out to assist with the construction of the fan diagram. To select the actuator and design the flap actuation region, the flap hinge moment is estimated via a CFD analysis. To obtain the desired flap deflection of ±4 .deg. , three actuators are required. The design of the flap actuation region is validated using a test bed with a skin hinge. However, because the skin hinge induces additional flap hinge moment, it does not provide sufficient deflection angle. Therefore, the flap hinge is replaced by a pin-type hinge, and the results are evaluated.

    Full Text Available Background. War wounds caused by modern infantry weapons or explosive devices are very often associated with the defects of soft and bone tissue. According to their structure, tissue defects can be simple or complex. In accordance with war surgical doctrine, at the Clinic for Plastic Surgery and Burns of the Military Medical Academy, free flaps were used in the treatment of 108 patients with large tissue defects. With the aim of closing war wounds, covering deep structures, or making the preconditions for reconstruction of deep structures, free flaps were applied in primary, delayed, or secondary term. The main criteria for using free flaps were general condition of the wounded, extent, location, and structure of tissue defects. The aim was also to point out the advantages and disadvantages of the application of free flaps in the treatment of war wounds. Methods. One hundred and eleven microvascular free flaps were applied, both simple and complex, for closing the war wounds with extensive tissue defects. The main criteria for the application of free flaps were: general condition of the wounded, size, localization, and structure of tissue defects. For the extensive defects of the tissue, as well as for severely contaminated wounds latissimus dorsi free flaps were used. For tissue defects of distal parts of the lower extremities, scapular free flaps were preferred. While using free tissue transfer for recompensation of bone defects, free vascularized fibular grafts were applied, and in skin and bone defects complex free osteoseptocutaneous fibular, free osteoseptocutaneous radial forearm, and free skin-bone scapular flaps were used. Results. After free flap transfer 16 (14,4% revisions were performed, and after 8 unsuccessful revisions another free flaps were utilized in 3 (37,5% patients, and cross leg flaps in 5 (62,5% patients. Conclusion. The treatment of war wounds with large tissue defects by the application of free microvascular flaps

The aim was to present and evaluate clinical experience and results in the radial forearm free transfer for intraoral reconstructions after resections due to malignancies. Methods. This article illustrates the versatility and reliability of forearm single donor site in 21 patients with a variety of intraoral oncologic defects who underwent immediate (19 patients, 90.5% or delayed (2 patients, 9.5% reconstruction using free flaps from the radial forearm. Fascio-cutaneous flaps were used in patients with floor of the mouth (6 cases, buccal mucosa (5 cases, lip (1 case and a retromolar triangle (2 cases defects, or after hemiglossectomy (7 cases. In addition, the palmaris longus tendon was included with the flap in 2 patients that required oral sphincter reconstruction. Results. An overall success rate was 90.5%. Flap failures were detected in two (9.5% patients, in one patient due to late ischemic necrosis, which appeared one week after the surgery, and in another patient due to venous congestion, which could not be salvaged after immediate re-exploration. Two patients required re-exploration due to vein thrombosis. The donor site healed uneventfully in all patients, except one, who had partial loss of skin graft. Conclusion. The radial forearm free flap is, due to multiple advantages, an acceptable method for reconstructions after resection of intraoral malignancies.

    Jefferson Lessa Soares de Macedo

    Full Text Available ABSTRACT OBJECTIVE: To study use of the medial plantar flap for reconstruction of the heel and foot. METHOD: The authors share their clinical experience with the use of the medial plantar artery flap for coverage of tissue defects around the foot and heel after trauma. Twelve cases of medial plantar artery flap performed from January 2001 to December 2013 were included. RESULTS: Of the 12 patients, ten were male and two were female. The indications were traumatic loss of the heel pad in ten cases and the dorsal foot in two cases. All the flaps healed uneventfully without major complications, except one case with partial flap loss. The donor site was covered with a split-thickness skin graft. The flaps had slightly inferior protective sensation compared with the normal side. CONCLUSION: From these results, the authors suggest that the medial plantar artery flap is a good addition to the existing armamentarium for coverage of the foot and heel. It is versatile flap that can cover defects on the heel, over the Achilles tendon and plantar surface, as well as the dorsal foot. It provides tissue to the plantar skin with a similar texture and intact protective sensation.

    Inflatable penile prostheses (IPPs) are associated with excellent long-term outcomes and patient/partner satisfaction. A small percentage of patients remain dissatisfied, despite acceptable surgical results. This study aims to evaluate factors associated with patient satisfaction and dissatisfaction, define patient characteristics, which may identify elevated risk of postoperative dissatisfaction, and describe management strategies to optimize functional and psychological patient outcomes. A review of urologic and non-urologic cosmetic surgery literature was performed to identify factors associated with patient satisfaction/dissatisfaction. Emphasis was placed on articles defining "high risk" or psychologically challenging patients. Preoperative factors associated with patient satisfaction/dissatisfaction and character traits, which may identify elevated risk of postoperative dissatisfaction or otherwise indicate a psychologically challenging patient. Contemporary patient and partner satisfaction rates following IPP are 92-100% and 91-95%, respectively. Factors associated with satisfaction include decreased preoperative expectations, favorable female partner sexual function, body mass index ≤30, and absence of Peyronie's disease or prior prostatectomy. Determinants of dissatisfaction include perceived/actual loss of penile length, decreased glanular engorgement, altered erectile/ejaculatory sensation, pain, diminished cosmetic outcome, difficulty with device function, partner dissatisfaction and perception of unnatural sensation, complications, and extent of alternative treatments offered. Personality characteristics which may indicate psychologically challenging IPP patients include obsessive/compulsive tendencies, unrealistic expectations, patients undergoing revision surgery, those seeking multiple surgical opinions, feeling of entitlement, patients in denial of their prior erectile/sexual function and current disease status, or those with other psychiatric

    2012-01-01

    Full Text Available Introduction. Soft tissue coverage of distal leg and ankle region represents a challenge and such defect usually requires a free flap. However, this may lead to considerable donor site morbidity, is time consuming, and needs facility of microsurgery. With the introduction of perforator flap, management of small- and medium-size defects of distal leg and ankle region is convenient, less time consuming, and with minimal donor site morbidity. When local perforator flap is designed as propeller and rotated to 180 degree, donor site is closed primarily and increases reach of flap, thus increasing versatility. Material and Methods. From June 2008 to May 2011, 20 patients were treated with perforator-based propeller flap for distal leg and ankle defects. Flap was based on single perforator of posterior tibial and peroneal artery rotated to 180 degrees. Defect size was from 4 cm × 3.5 cm to 7 cm × 5 cm. Results. One patient developed partial flap necrosis, which was managed with skin grafting. Two patients developed venous congestion, which subsided spontaneously without complications. Small wound dehiscence was present in one patient. Donor site was closed primarily in all patients. Rest of the flaps survived well with good aesthetic results. Conclusion. The perforator-based propeller flap for distal leg and ankle defects is a good option. This flap design is safe and reliable in achieving goals of reconstruction. The technique is convenient, less time consuming, and with minimal donor site morbidity. It provides aesthetically good result.

    Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high

    The purpose of this prospective cohort study was to evaluate patient-based outcomes and complications following excision of mucous cysts, joint debridement, and closure with one of three types of local flaps. From 2000-2011, 35 consecutive patients with 37 digital mucous cysts were treated surgically. The surgical procedure included excision of the cyst together with the attenuated skin, joint debridement on the affected side including capsulectomy, and removal of osteophytes. Depending on the size and location of the cyst, the skin defect was covered by a transposition flap (31 cysts), an advancement flap (two cysts), or a rotation flap (four cysts). At an average follow-up time of 4 years, 4 months, there was no wound infection, flap necrosis, or joint stiffness. Preoperative nail ridging resolved in seven of nine fingers, and no nail deformities developed after surgery. One cyst, treated with a transposition flap, recurred 10 months after surgery. The average satisfaction score for the affected finger significantly improved from 4.3 to 6.8, and the average pain score decreased from 4.7 to 2.3. This treatment protocol provides reliable results. Patients were satisfied with the reduction of associated pain and the postoperative appearance of the treated finger, and postoperative complications were minimal.

    Full Text Available Covering of large wounds after mastectomy in locally advanced Ca breast with skin that can withstand radiotherapy is a challenge to the surgeon. Here this study we used a local advancement flap from the adjacent area called Thoraco - A bdominal F la p (TA flap for such giant defects. This is based on superficial and lumbar arteries and is thick to with stand consequent RT . MATERIALS AND METHODS: Of the total 107 cases of LABC 32 had post mastectomy defects of larger than 12 cm and could not be closed by simple approximation. Among the 32 cases 17 cases are covered by split thickness skin grafting. 15 cases are covered by TA flap. These cases are assessed for mean operating time, mean blood loss, post - operative stay, flap necrosis and viability of the f lap after radiotherapy. RESULTS: There is minimal extra time or blood loss in these cases . All the flaps healed well except for small edge necrosis in 4 cases. In all the patients we could start radiotherapy in the fourth week of surgery and all the flaps withstood RT well. After further evaluation probably this can be recommended as procedure for giant post mastectomy defects particularly for those who require RT early

    Self-insertion of penile foreign bodies is performed worldwide, largely due to a perception that it will enhance sexual performance and virility. There are relatively few cases reported in the United States. We report three cases of Hispanic men incarcerated in separate southwest United States prisons who utilized a similar technique to insert foreign bodies fabricated out of dominos into the subcutaneous tissues of the penis. Details of the three cases were retrospectively reviewed. Resolution of the case. In each case, an incarcerated Hispanic male or fellow inmate filed a domino into a unique shape for placement under the penile skin. Utilizing the tip of a ballpoint pen or a sharpened shard of plastic to create a puncture wound, each man inserted the domino fragment into the subcutaneous tissue of the penis. All three men presented with infection requiring operative removal. Incarcerated males put themselves at risk for injury and infection when attempting penile enhancement with improvised equipment. © 2011 International Society for Sexual Medicine.

  20. Active Control of Long Bridges Using Flaps

    DEFF Research Database (Denmark)

    Hansen, H. I.; Thoft-Christensen, Palle

    The main problem in designing ultra-long span suspension bridges is flutter. A solution to this problem might be to introduce an active flap control system to increase the flutter wind velocity. The investigated flap control system consists of flaps integrated in the bridge girder so each flap...... is the streamlined part of the edge of the girder. Additional aerodynamic derivatives are shown for the flaps and it is shown how methods already developed can be used to estimate the flutter wind velocity for a bridge section with flaps. As an example, the flutter wind velocity is calculated for different flap...... configurations for a bridge section model by using aerodynamic derivatives for a flat plate. The example shows that different flap configurations can either increase or decrease the flutter wind velocity. for optimal flap configurations flutter will not occur....

    2003-01-01

    During the past 10 years, seven pedicled rectus femoris muscle or musculocutaneous flaps were used to repair lower abdominal defects; three recalcitrant incisional hernias with previous radiotherapy, two long-standing wound infections after synthetic mesh reconstruction, one posttraumatic wall defect and one metastatic tumor. There were two flap complications, one skin paddle necrosis and one wound infection. There was no significant disability of the donor limb encountered. During the two-year and seven month average follow-up, there was no recurrence of the problems except for one minor fascial dehiscence in the patient with metastatic abdominal wall tumor. Easy approach, rapid harvest, relatively large and reliable overlying fascia lata, a single dominant neurovascular pedicle, easy primary closure of the donor site, and minimal donor site morbidity all make the rectus femoris flap a good alternative flap for lower abdominal wall reconstruction. It is especially useful in a condition where synthetic mesh would be unsuitable for defects with infection or recurrent incisional hernia after radiotherapy. (author)

    Abstract Rationale: Necrotizing fasciitis (NF), characterized by widespread fascial necrosis, is a rare disease in clinic. Fournier gangrene (FG) is a special type of NF involved of perineum and scrotum. To our knowledge, no article has reported on bilateral femoral posterior neurocutaneous perforater flap treating for FG. Patient concerns: A 61-year-old Chinese male complained of perineal skin necrosis for 19 days. The patient received treatment in other hospital due to chronic bronchitis on April 15th and body temperature ranged from 38 to 39 °C. Then he received antiinfection therapy. Perianal cutaneous occurred mild necrosis on May 08th. And the necrosis generally deteriorated. He came to our hospital for treating necrosis in area of perineum and scrotum on May 28th. Diagnoses: He was diagnosed with FG and chronic bronchitis. Interventions: The patient underwent debridement on June 2nd and received bilateral femoral posterior neurocutaneous perforater flap on June 29th. Besides, the patient was treated with whole-body nutrition support and antibiotic treatment. Outcomes: One week after the 2nd operation, the flap showed normal color. The result shows good outcome and no recurrence of the clinical symptoms occur till now. Lessons: FG is rare. Bilateral femoral posterior neurocutaneous perforater flap is an effective procedure to treat FG. The outcome of combined therapy is satisfactory. PMID:29145312

    The objective is to analyze the utility of the island supraclavicular flap in a region where skin graft cannot be used and free flap is not feasible. We assessed complications and functional outcomes. Study Design: Prospective descriptive study. Place and Duration of Study: The study was done at plastic and reconstructive surgery department CMH Rawalpindi during the period of 03 year from October 2011 to October 2014. Material and Patients: An island supraclavicular artery flap was used to reconstruct oncologic, and post burn neck contractures release defects. 30 patients were included in the study. Doppler probe was used to help with localization of vascular pedicle. All the patients with scarring in both shoulder regions, history of radiation to neck and undergoing radical neck dissection were excluded. Results: A total of 30 patients were included 20 (66.6%) male and 10 (33.3%) were female. Oncologicre section was followed by immediate reconstruction with island supraclavicular artery flap. Post burn contractures were released and covered by a pedicled supraclavicular artery flap. The recipient sites were neck, face, oral and upper chest region. The average harvest time was 1 and half hour. Donor site was closed primarily in 22 (73.3%) while 8 (26.6%) require skin grafting. Post burn contractures needed scar management with intralesional steroid, pressure garments and scar revision with Z-plasty in 4(13.3%) cases. 1 (3.3%) flap failed completely and the defect was covered with a skin graft. We had 01 (3.3%) mortality due to respiratory obstruction, despite adequate flap perfusion for 24 hours. Minor complications included, partial flap loss, seroma, and haematoma formation. In addition hypertrophied scar, spreading scar and keloid formation occurred at the donor site 18 (60%). Conclusion: Island supraclavicular artery flap with an easy learning curve is a reliable flap. It has a good colour and texture match with minimal donor site morbidity. It is an excellent

    Full Text Available A case of reconstruction after penile skin avulsion is described in an eight-year-old boy. Penile coverage was gained by use of the avulsed skin flap itself, without a graft or local tissue flap. The procedure avoids any valuable time delay; thus, enhancing the chances to obtain adequate flap viability, avoids patient discomfort caused by perineal expansion, gives a satisfactory cosmetic appearance, and taking into account his age, avoids future psychosomatic and psychosexual problems.

    A 67-year-old man visited our hospital with complaints of scrotal swelling associated with occasional febrile episodes. Physical examination disclosed a huge scrotal mass, approximately the size of a child`s head, with numerous papillomatous lesions in its surface. His past medical history was significant in that he was diagnosed with penile carcinoma at the age of 35 years old and was treated with partial penectomy followed by radiation and chemotherapy at other hospital. During this admission tumor marker squamous cell carcinoma (SCC) and microbiological tests for microfilariae were both negative. Ultrasound (US), computed tomographic (CT) scan and magnetic resonance imaging (MRI) revealed markedly thickened scrotal skin and small hydrocele with no evidence of local recurrence of the previous penile carcinoma. A percutaneous cystostomy was created because of chronic urinary retention and possible urine extravasation into the scrotum. Histopathological examination of the biopsy specimen from the scrotal mass demonstrated lymphagiectasia consistent with elephantiasis of the scrotum. Surgical excision of this huge scrotal mass was performed in August 1997. The resected tissue weighted 1,400 g. Convalescene was uneventful. He subsequently underwent perineal urethrostomy in place of the suprapubic cystostomy. (author)

    Since 14 years of age, the patient had experienced extreme penile pain within seconds of initial sexual arousal through masturbation. Penile pain was so severe that he rarely proceeded to orgasm or ejaculation. After 7 years of undergoing multiple unsuccessful treatments, he was concerned for his long-term mental health and for his future ability to have relationships. To describe a novel collaboration among specialists in sexual medicine, neurophysiology, and spine surgery that led to successful management. Collaborating health care providers conferred with the referring physician, patient, and parents and included a review of all medical records. Elimination of postpubertal intense penile pain during sexual arousal. The patient presented to our sexual medicine facility at 21 years of age. The sexual medicine physician identifying the sexual health complaint noted a pelvic magnetic resonance imaging report of an incidental sacral Tarlov cyst. A subsequent sacral magnetic resonance image showed four sacral Tarlov cysts, with the largest measuring 18 mm. Neuro-genital testing result were abnormal. The neurophysiologist hypothesized the patient's pain at erection was produced by Tarlov cyst-induced neuropathic irritation of sensory fibers that course within the pelvic nerve. The spine surgeon directed a diagnostic injection of bupivacaine to the sacral nerve roots and subsequently morphine to the conus medullaris of the spinal cord. The bupivacaine produced general penile numbness; the morphine selectively decreased penile pain symptoms during sexual arousal without blocking penile skin sensation. The collaboration among specialties led to the conclusion that the Tarlov cysts were pathophysiologically mediating the penile pain symptoms during arousal. Long-term follow-up after surgical repair showed complete symptom elimination at 18 months after treatment. This case provides evidence that (i) Tarlov cysts can cause sacral spinal nerve root radiculitis through

    Full Text Available Background The free anterolateral thigh (ALT flap has been widely used for various kinds of reconstructions. However, delayed healing at the donor site occasionally occurs due to wound dehiscence or the partial loss of grafted skin at the donor site. The aim of the present study was to identify reliable predictive factors for delayed healing at the donor site after the harvest of a free ALT flap. Methods This study included 52 patients who underwent reconstructive procedures using free ALT flaps. The delayed healing group included patients with wounds at the donor site that had not healed over 3 weeks after surgery, and the normal healing group included patients who showed wound healing within 3 weeks after surgery. Multivariate logistic regression models were created to identify the risk factors for delayed healing at the ALT flap donor site. Results Among the 52 patients, 24 (46.2% showed delayed healing at the donor site, and 6 patients required additional operative treatment. A high preoperative body mass index (BMI, smoking, and skin grafting were found to be significantly associated with delayed healing at the ALT donor site. Of the 37 patients who underwent skin grafting, 23 (62% experienced delayed healing at the donor site. Conclusions A high preoperative BMI, smoking, and skin grafting were risk factors for delayed healing at the free ALT donor site. Skin grafting at the ALT donor site should be avoided in patients with a high BMI or a habit of smoking.

    Reconstruction of the nasal clefts is a challenging task considering the nasal anatomic complexity and their possible association with craniofacial defects. The reconstruction of these defects needs extensive amounts of soft tissue that warrant the use of forehead flaps. Often presence of cranial defects and low hairline compromise the amount of tissue available for reconstruction warrenting tissue expansion. To evaluate the efficacy of tissue expansion in reconstruction of congenital nasal clefts. 9 patients with congenital nasal clefts involving multiple sub units were taken up for nasal reconstruction with expanded forehead flaps. The average amount of expansion needed was 200 ml. The reconstruction was performed in 3 stages. Expanded forehead flaps proved to be best modality for reconstruction providing the skin cover needed for ala, columella and dorsum with minimal scarring at the donor site. Expansion of the forehead flap is a viable option for multiple sub unit reconstruction in congenital nasal cleft deformities.

    Full Text Available Severe soft tissue defects as a result of lye contamination remain a huge challenge in the interdisciplinary approach of trauma surgeons and plastic surgeons. Free tissue transfer is a suitable surgical option for successful reconstruction of form and function of defects in the distal parts of the lower extremities. We report the successful two-stage reconstruction of a full thickness lye contamination at the dorsum of the foot with a free temporoparietal fascia flap covered with a split-thickness skin graft from the thigh. The described method is a suitable operative alternative to anterolateral thigh flaps or other thin fascia flaps regarding flap harvest and donor site morbidity and should be considered in the portfolio of the plastic surgeon.

  12. A TRAM flap design refinement for use in delayed breast reconstruction.

    Autologous breast reconstruction following mastectomy is commonly achieved using the free Transverse Rectus Abdominis Myocutaneous (TRAM) flap. Since its first description, refinements and modifications have resulted in improved operative techniques and more aesthetically pleasing reconstructions. Pre-operative flap design, however, is a relatively new concept that has not received much attention in the literature. Patients who undergo breast reconstruction may have large, ptotic contralateral breasts. In these patients there is a tendency to raise a large abdominal flap in an attempt to achieve symmetry, or simply a larger breast. This has the potential to lead to tight closure of the abdomen and the risk of subsequent wound problems. Reconstructions that are too small or have inadequate ptosis commit the patient to contralateral breast surgery to achieve symmetry. Pre-operatively designing the flap, using a template created from the opposite breast, can help achieve a good match, often reducing the need for contralateral breast surgery. Even when contralateral breast reduction surgery is planned in advance, many of these patients still require, and prefer, a large reconstruction in order to achieve a well-proportioned result. We present a design template that addresses these particular issues and in the senior author\\'s hands has proved to be a very effective technique. Our technique allows raising an abdominal flap of less vertical height than traditionally used (thus reducing the risk of tight abdominal closure) and incorporates an inverted V-shaped flap of skin from the inferior mastectomy skin flap into the reconstruction. This allows more flap tissue to be available to fill the upper poles of the reconstructed breast and at the same time produces good ptosis.

    2012-08-01

    The ulnar forearm fasciocutaneous flap (UFFF) is a favourable alternative to the radial forearm flap when thin and pliable tissue is required. The precise anatomy of the cutaneous perforators of UFFF has not been previously reported. The position of cutaneous perforators>0.5 mm was recorded while raising 52 consecutive free UFFFs in 51 patients at our Centre. Three (6%) UFFFs in two patients demonstrated direct cutaneous supply through a superficial ulnar artery, a known anatomic variance. There was no cutaneous perforator>0.5 mm in one flap. Among the remaining 48 dissections, an average of 3 (range, 1-6) cutaneous perforators were identified. Ninety-four percent of these forearms demonstrated at least one perforator>0.5 mm within 3 cm, and all had at least one perforator within 6 cm of the midpoint of the forearm. Proximal perforators were more likely to be musculo-cutaneous through the edge of flexor carpi ulnaris or flexor digitorum superficialis, while mid- to distal perforators were septo-cutaneous. UFFF skin paddle designed to overlie an area within 3 cm of the midpoint between the medial epicondyle and the pisiform is most likely to include at least one cutaneous perforator from the ulnar artery, without a need for intra-operative skin island adjustment. This novel anatomic finding and other practical generalisations are discussed to facilitate successful elevation of UFFF.

    Hutcheson, Florence V.; Stead, Daniel J.

    2004-01-01

    PIV measurements of the flow in the region of a flap side edge are presented for several blowing flap configurations. The test model is a NACA 63(sub 2)-215 Hicks Mod-B main-element airfoil with a half-span Fowler flap. Air is blown from small slots located along the flap side edge on either the top, bottom or side surfaces. The test set up is described and flow measurements for a baseline and three blowing flap configurations are presented. The effects that the flap tip jets have on the structure of the flap side edge flow are discussed for each of the flap configurations tested. The results indicate that blowing air from a slot located along the top surface of the flap greatly weakened the top vortex system and pushed it further off the top surface. Blowing from the bottom flap surface kept the strong side vortex further outboard while blowing from the side surface only strengthened the vortex system or accelerated the merging of the side vortex to the flap top surface. It is concluded that blowing from the top or bottom surfaces of the flap may lead to a reduction of flap side edge noise.

    Some sensation to the breast returns after breast reconstruction, but recovery is variable and unpredictable. We primarily sought to assess the impact of different types of breast reconstruction [deep inferior epigastric artery perforator (DIEP) flaps versus implants] and radiation therapy on the return of sensation. Thirty-seven patients who had unilateral or bilateral breast reconstruction via a DIEP flap or implant-based reconstruction, with or without radiation therapy (minimum follow-up, 18 months; range, 18-61 months) were studied. Of the 74 breasts, 27 had DIEP flaps, 29 had implants, and 18 were nonreconstructed. Eleven breasts with implants and 10 with DIEP flaps had had prereconstruction radiation therapy. The primary outcome was mean patient-perceived static and moving cutaneous pressure threshold in nine areas. We used univariate and multivariate analyses to assess what independent factors affected the return of sensation (significance, P sensation (P = 0.041) than did DIEP flaps. However, among irradiated breasts, skin over DIEP flaps had significantly better sensation than did that over implants (static, P = 0.019; moving, P = 0.028). Implant reconstructions with irradiated skin had significantly worse static (P = 0.002) and moving sensation (P = 0.014) than did nonirradiated implant reconstructions. Without irradiation, skin overlying implants is associated with better sensation recovery than DIEP flap skin. However, with irradiation, DIEP flap skin had better sensation recovery than did skin over implants. Neurotization trended toward improvement in sensation in DIEP flaps.

    Pressure ulcers refractory to nonoperative management may undergo flap reconstruction. This study aims to evaluate the long-term outcomes and recurrence rates of flap reconstruction for pediatric pressure ulcers. We reviewed the records of patients who underwent flap reconstruction for pressure ulcer(s) from 1995 to 2013. Twenty-four patients with 30 pressure ulcers, requiring 52 flaps were included. Ulcers were stages III and IV and mostly involved either the ischia (15/30) or sacrum (8/30). Flaps were followed for a median of 4.9 years. Twenty-three patients were wheelchair dependent, and 20 had sensory impairment at their ulcer site(s). Ten patients had a history of noncompliance with preoperative management, 8 of whom experienced ulcer recurrence. Twenty-one ulcers had underlying osteomyelitis, associated with increased admissions (P = 0.019) and cumulative length of stay (P = 0.031). Overall, there was a 42% recurrence rate in ulceration after flap reconstruction. Recurrence was associated with a preoperative history of noncompliance with nonoperative therapy (P = 0.030), but not with flap type or location, age, sex, body mass index, osteomyelitis, or urinary/fecal incontinence (P > 0.05, all). Flap reconstruction can be beneficial in the management of pediatric pressure ulcers. Although high rates of long-term success with this intervention have been reported in children, we found rates of ulcer recurrence similar to that seen in adults. Poor compliance with nonoperative care and failure to modify the biopsychosocial perpetuators of pressure ulcers will likely eventuate in postoperative recurrence. Despite the many comorbidities observed in our patient sample, compliance was the best indicator of long-term skin integrity and flap success.

  17. Pedicled Instep Flap and Tibial Nerve Reconstruction in a Cynomolgus Monkey [Macaca fascicularis

    2016-01-01

    Full Text Available A male cynomolgus monkey experienced extensive soft tissue trauma to the right caudal calf area. Some weeks after complete healing of the original wounds, the monkey developed a chronic pressure sore on plantar surface of the heel of its right foot. A loss of sensitivity in the sole of the foot was hypothesized. The skin defect was closed by a medial sensate pedicled instep flap followed by counter transplantation of a full thickness graft from the interdigital webspace. The integrity of the tibial nerve was revised and reconstructed by means of the turnover flap technique. Both procedures were successful. This is an uncommon case in an exotic veterinary patient as it demonstrates a reconstructive skin flap procedure for the treatment of a chronic, denervated wound in combination with the successful reconstruction of 2.5 cm gap in the tibial nerve.

    We have developed a penile nonimaging scintillation (PNIS) probe consisting of a plastic well-type scintillation crystal interfaced to a portable computer and acquisition board. This report describes the design of the PNIS probe, performance characteristics, mode of usage and illustrative results which demonstrate its capabilities. With the PNIS probe, penile blood-pool studies were performed in nine patients utilizing 3.7 MBq (100 microCi) autologous 99mTc-labeled red blood cells (RBCs). Venous blood standards were assayed to enable conversion of the count rate to volummetric measurements. Washin of peripherally administered 99mTc-RBCs was mathematically analyzed to estimate penile blood volume and cavernosal flow rate in the flaccid state. The rate of change of penile blood volume after intracavernosal vasodilators was used to generate measures of stimulated flow. A major advantage of this device over the gamma-camera is a 3300-fold increase in count rate sensitivity, which allows for markedly improved temporal resolution while significantly reducing the radiopharmaceutical dosage. Additionally, the PNIS probe is portable, economical and is not dependent on operator-defined regions of interest. Count rate sensitivity is relatively constant within the bore, with the exception of the proximal region adjacent to the opening, where geometric efficiency is reduced. The PNIS probe is an effective device for measuring penile activity in radionuclide studies, allowing for acquisition of time-activity curves of the penis during flaccid washin of peripherally labeled red blood cells and after pharmacologic stimulation to induce erection.

    The effects of the interaction of a wake with a half-span flap on radiated noise are examined. The incident wake is generated by bars of various widths and lengths or by a simplified landing gear model. Single microphone and phased array measurements are used to isolate the effects of the wake interaction on the noise radiating from the flap side edge and flap cove regions. The effects on noise of the wake generator's geometry and relative placement with respect to the flap are assessed. Placement of the wake generators upstream of the flap side edge is shown to lead to the reduction of flap side edge noise by introducing a velocity deficit and likely altering the instabilities in the flap side edge vortex system. Significant reduction in flap side edge noise is achieved with a bar positioned directly upstream of the flap side edge. The noise reduction benefit is seen to improve with increased bar width, length and proximity to the flap edge. Positioning of the landing gear model upstream of the flap side edge also leads to decreased flap side edge noise. In addition, flap cove noise levels are significantly lower than when the landing gear is positioned upstream of the flap mid-span. The impact of the local flow velocity on the noise radiating directly from the landing gear is discussed. The effects of the landing gear side-braces on flap side edge, flap cove and landing gear noise are shown.

    Conclusions: There is an increased utilization of penile prosthetics in Saudi Arabia. The private sector performs the majority of penile prosthesis procedures, and most of them are of the semirigid type. The governmental sector is more likely to perform inflatable penile prosthesis and male incontinence device procedures. Male incontinence prosthetics' use is very limited in Saudi Arabia.

    Full Text Available Kaposi's sarcoma (KS of the penis is a very rare lesion and it is usually observed in HIV-infected patients. We introduce a case of KS of the penis in a 75 years old HIV negative patient with a peripheral T-cell lymphoma. He came to our attention with a painful ulcerated red lesion on the glans that stretched from the urethral meatus to the coronal skin. This lesion was found to be a KS balanopreputial in the classical variant. Penile KS must be included in the differential diagnosis of genital diseases especially when the clinical features of the lesion are aspecific and diagnosis can be made histologically by performing a biopsy.

    Full Text Available ABSTRACT: The most common skin lesions in small animals result from trauma, burns, or surgical resection of large tumors. Given the high importance of reconstructive surgery associated with tumors in small animals, this study reports four cases of reconstructive surgery using subcutaneous and axial tubular flaps in animals with neoplastic lesions. Subdermal and axial tubular flaps are healthy alternatives for reconstructing wounds caused by large tumor resection in areas with poor tissue elasticity.

    Full Text Available Objective: To explore the feasibility of the submental island flap in the repair of hypopharyngeal defects. Methods: We collected wet specimens of fresh cadaveric heads from the Han Chinese adult population for applied anatomy of the submental island flap, and followed five patients with pyriform sinus carcinoma after reconstruction surgery using submental island flaps. Results: We found that the average length and width of the submental island flaps were (65.20 ± 11.69 mm and (46.70 ± 6.59 mm, respectively. The skin flap in all five patients survived after surgery, and tracheal tubes and gastric tubes were removed 7–36 days after surgery. Patients were followed up for 24–42 months, pharyngeal flaps grew well, and speech and swallowing functions were satisfactory. Conclusion: The submental island flap is a preferred material for the repair of hypopharyngeal defects after hypopharyngeal carcinoma resection, because of good blood supply, easy harvesting, and high survival rate.

    Full Text Available Total nail ablation for the treatment of onychodystrophies can be performed by using chemicals, surgical resection or laser ablation of nail matrix. A female patient with bilateral severe onychodystrophy as a result of inadvertent previous nail surgeries was treated surgically. Proximal complete nail matrix resection and distal 10 mm wide transverse strip partial nail bed resection were performed. A 5 mm wide transverse strip of nail bed was left intact proximally. Proximal nail matrix defect was closed by using the skin of proximal nail fold. The distal nail bed defect was reconstructed by using triple flap technique which was composed of a main central advancement flap containing ventral toe skin and two side flaps containing nail fold skin. The patient healed without any problem and her nail problem was treated successfully. The cosmetic appearance of her first toes was acceptable. Surgical nail ablation followed by volar skin coverage of dorsal surface of the distal phalanx bone by using triple flap technique is an effective surgical treatment method for the correction of advanced nail plate deformities requiring total nail ablation.

    Invasive penile cancer is a rare disease with an approximately 22 000 cases per year. The incidence is higher in less developed countries, where penile cancer can account for up to 10% of cancers among men in some parts of Africa, South America, and Asia. To describe the human papillomavirus (HPV) DNA prevalence, HPV type distribution, and detection of markers of viral activity (ie, E6*I mRNA and p16(INK4a)) in a series of invasive penile cancers and penile high-grade squamous intraepithelial lesions (HGSILs) from 25 countries. A total of 85 penile HGSILs and 1010 penile invasive cancers diagnosed from 1983 to 2011 were included. After histopathologic evaluation of formalin-fixed paraffin-embedded samples, HPV DNA detection and genotyping were performed using the SPF-10/DEIA/LiPA25 system, v.1 (Laboratory Biomedical Products, Rijswijk, The Netherlands). HPV DNA-positive cases were additionally tested for oncogene E6*I mRNA and all cases for p16(INK4a) expression, a surrogate marker of oncogenic HPV activity. HPV DNA prevalence and type distributions were estimated. HPV DNA was detected in 33.1% of penile cancers (95% confidence interval [CI], 30.2-36.1) and in 87.1% of HGSILs (95% CI, 78.0-93.4). The warty-basaloid histologic subtype showed the highest HPV DNA prevalence. Among cancers, statistically significant differences in prevalence were observed only by geographic region and not by period or by age at diagnosis. HPV16 was the most frequent HPV type detected in both HPV-positive cancers (68.7%) and HGSILs (79.6%). HPV6 was the second most common type in invasive cancers (3.7%). The p16(INK4a) upregulation and mRNA detection in addition to HPV DNA positivity were observed in 69.3% of HGSILs, and at least one of these HPV activity markers was detected in 85.3% of cases. In penile cancers, these figures were 22.0% and 27.1%, respectively. About a third to a fourth of penile cancers were related to HPV when considering HPV DNA detection alone or adding an HPV

    To determine the incidence of isolated neonatal penile glanular torsion, describe the basic characteristics, and explore the relationship between foreskin and glans torsion. A prospective survey was conducted of all male newborns admitted to nursery after delivery, or neonates less than 3 months presenting for circumcision. Cases with associated genital malformations were excluded. The incidence of isolated neonatal penile torsion was 27% (95% CI: 22.2%-31.84%), to the left in 99% of cases. In 3.5% of cases, the penis had an angle 20 degrees. Using Spearman's correlational coefficient, deviation of penile raphe from the midline at the foreskin tip had a better correlation with glans torsion than deviation of raphe at the coronal sulcus (0.727 vs 0.570; both significant at pscope of the study.

    Full Text Available OBJECTIVE: To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. MATERIALS AND METHODS: The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospectively analyzed. RESULTS: Of 43 cases assessed, 41 were submitted to surgical exploration (95.3% and 2 were submitted to conservative treatment (4.7%. We found penile lesions involving the corpus cavernosum in 37 cases; the remaining 4 patients presented no lesions involving the corpus cavernosum, urethra or testicles but did in the superficial structures. Ten cases presented an association with testicular lesions and 14 cases association with anterior urethral lesions. CONCLUSION: Penile lesions from gunshot wounds should be treated with immediate surgical intervention. In exceptional situations featuring superficial lesions only conservative treatment may be applied.

  11. Henoch-Schonlein purpura: ultrasonography of scrotal and penile involvement

    2015-04-01

    Full Text Available Testicular or scrotal involvement has been reported in children with Henoch-Schonlein purpura (HSP, but there are very few reports on penile involvement. We report the initial and follow-up ultrasonographic findings of scrotal and penile involvement of HSP in a 5-year-old boy. On ultrasonography, scrotal soft tissue thickening and epididymal swelling with increased vascularity were noted, and on the penis, a focal mass-like lesion appeared on the dorsal surface of the distal penis, having a hypoechoic mass-like appearance without visible vascular flow on a Doppler study. After 2 days of treatment, follow-up ultrasonography showed normal scrotum and penis with a resolved soft tissue mass-like lesion. Therefore, we think that HSP ultrasonographic findings involving the scrotum and penis might help to diagnose scrotal and penile involvement in a case of HSP and to avoid unnecessary medication and/or surgical procedures.

  13. Efficient flapping flight of pterosaurs

    Science.gov (United States)

    Strang, Karl Axel

    In the late eighteenth century, humans discovered the first pterosaur fossil remains and have been fascinated by their existence ever since. Pterosaurs exploited their membrane wings in a sophisticated manner for flight control and propulsion, and were likely the most efficient and effective flyers ever to inhabit our planet. The flapping gait is a complex combination of motions that sustains and propels an animal in the air. Because pterosaurs were so large with wingspans up to eleven meters, if they could have sustained flapping flight, they would have had to achieve high propulsive efficiencies. Identifying the wing motions that contribute the most to propulsive efficiency is key to understanding pterosaur flight, and therefore to shedding light on flapping flight in general and the design of efficient ornithopters. This study is based on published results for a very well-preserved specimen of Coloborhynchus robustus, for which the joints are well-known and thoroughly described in the literature. Simplifying assumptions are made to estimate the characteristics that can not be inferred directly from the fossil remains. For a given animal, maximizing efficiency is equivalent to minimizing power at a given thrust and speed. We therefore aim at finding the flapping gait, that is the joint motions, that minimize the required flapping power. The power is computed from the aerodynamic forces created during a given wing motion. We develop an unsteady three-dimensional code based on the vortex-lattice method, which correlates well with published results for unsteady motions of rectangular wings. In the aerodynamic model, the rigid pterosaur wing is defined by the position of the bones. In the aeroelastic model, we add the flexibility of the bones and of the wing membrane. The nonlinear structural behavior of the membrane is reduced to a linear modal decomposition, assuming small deflections about the reference wing geometry. The reference wing geometry is computed for

    We study the effect of passive pitching and flexible deflection of wings on the forward flapping flight. The wings are flapped vertically in water and are allowed to move freely horizontally. The forward speed is chosen by the flapping wing itself by balance of drag and thrust. We show, that by allowing the wing to passively pitch or by adding a flexible extension at its trailing edge, the forward speed is significantly increased. Detailed measurements of wing deflection and passive pitching, together with flow visualization, are used to explain our observations. The advantage of having a wing with finite rigidity/flexibility is discussed as we compare the current results with our biological inspirations such as birds and fish.

    Full Text Available Skin avulsions of male genitals are a rare traumatic plastic surgery and urologic emergency. This kind of trauma occur mainly because of accidents with industrial machines or agricultural machine belts. In this paper we reported two patients with traumatic avulsion of penile and scrotal skin. These patients wound were covered with split thickness skin graft after two weeks. We recommend for using a split thickness skin graft to cover the penis and scrotal degloved area because of this operation has minimal invasiveness and rapid healing.

    Full Text Available INTRODUCTION: P ost electric burn defects are difficult to manage due to deep injury involving all the structures up to bony level. A good vascularized flap is required to resurface the defect for preventing the complication and for reconstruction of involved structures. AIM: Resurfacing the post electric burn defect with different flaps according to need of the defect. MATERIAL AND METHOD: All patients of electric burn hand and fore arm defect admitted to burn, p lastic and reconstructi ve department of SCB Medical College &hospital, Cuttack between January 2012 to December 2012 were included in the study. During this period the patients were followed up at weekly interval for first 2 month, then at 1 monthly interv al for next 6 - 8 month. OBSERVATION: Out of 40 cases of post electric burn forearm and hand reconstruction, 10 cases underwent groin flap cover, 6 cases underwent abdominal flap cover, 5 cases underwent cross finger flap cover 5 cases underwent free antero lateral thigh flap cover, 4 cases underwent free latissimus dorsi flap cover, 5 cases underwent first dorsal metacarpal artery flap cover, 5 cases reverse radial forearm flap cover. All the defects were resurfaced successfully with flaps. Four had marginal necrosis and six had wound infection. Eventually all flaps settled well without further intervention. Due to involvement of all important tendons & nerves, functional outcome is guarded. DISCUSSION: Hand and forearm are most commonly and most severely aff ected in electric burn injury because they are mostly first part of body to come in contact with electric circuit. Even though at initial part the injury appears to be superficial, deepe r structures like bone, tendon and neurovascular bundles are affected requiring flap cover for future reconstruction of these structures to get functional and sensate hand. CONCLUSION: Reconstruction of post electric burn defect of distal forearm and hand represents great challenge due to

    The presentation of the cult of phallus in ancient Greece and the artistic appearance of the phenomenon on vase figures and statues, as indicative of the significant role of the male genitalia in all fertility ceremonies. The examination of a great number of penile representations from the ancient Greek pottery and sculpture and the review of the ancient theater plays (satiric dramas and comedies ). Phallus in artistic representation is connected either with gods of fertility, such as the goat-footed and horned Pan or the ugly dwarf Priapus or the semi-animal nailed figures Satyrs, devotees of the god Dionysus accompanying him in all ritual orgiastic celebrations. Phallus also symbolizes good luck, health and sexuality: people bear or wear artificial phalli exactly like the actors as part of their costume or carry huge penises during the festive ritual processions. On the contrary, the Olympic gods or the ordinary mortals are not imaged ithyphallic; the ideal type of male beauty epitomized in classical sculpture, normally depicts genitals of average or less than average size. It is noteworthy that many of these images belong to athletes during or immediately after hard exercise with the penis shrunk. The normal size genitalia may have been simply a convention to distinguish normal people from the gods of sexuality and fertility, protectors of the reproductive process of Nature. The representation of the over-sized and erected genitalia on vase figures or statues of ancient Greek art is related to fertility gods such as Priapus, Pan and Satyrs and there is strong evidence that imagination and legend were replacing the scientific achievements in the field of erectile function for many centuries.

    Two work-horse approaches to postmastectomy breast reconstruction are the deep inferior epigastric perforator flap and the superior gluteal artery perforator (SGAP) flap [and its variation, the lateral septocutaneous superior gluteal artery perforator flap]. Our purpose was fourfold: 1) to analyze our experience with the SGAP flaps for simultaneous bilateral breast reconstruction; 2) to analyze our experience with lateral septocutaneous superior gluteal artery perforator flaps for that procedure; 3) to compare our results with those in the literature; and 4) to highlight the importance of preoperative three-dimensional computed tomographic angiography. A retrospective chart review was completed for 23 patients who underwent breast reconstruction between December 2005 and January 2010 via an SGAP flap (46 flaps). We reviewed flap weight, ischemia time, length of stay, overall flap survival, fat necrosis development, and emergency re-exploration. Mean weights were 571.2 ± 222.0 g (range 186-1,117 g) and 568.0 ± 237.5 g (range 209-1,115 g) for the left and right buttock flap, respectively. Mean ischemia time was 129.1 ± 15.7 and 177.7 ± 24.7 minutes for the first and second flap, respectively. Mean hospital stay was 5.3 ± 2.5 days. All flaps survived. Fat necrosis developed in five flaps (10.8%), and emergency re-exploration was required in three patients (three flaps). When harvesting abdominal tissue is a poor option, the SGAP flap is an efficacious procedure for patients desiring autologous breast reconstruction, and bilateral procedures can be performed simultaneously.

    2015-08-01

    We report the case of a 50-year-old paraplegic man with a complicated grade III/IV ischiatic pressure sore treated with a propeller flap based on the first perforator of the profunda femoris artery. Our aim was to surgically reconstruct an ischiatic pressure sore in a patient with ankylosis using a fasciocutaneous perforator propeller flap obtained from the posterior region of the thigh. Our decision to perform a profunda femoris artery perforator propeller flap reconstruction was mainly due to the anatomical contiguity of the flap with the site of the lesion and the good quality of the skin harvested from the posterior region of the thigh. The use of the perforator fasciocutaneous flap represents a muscle-sparing technique, providing a better long-term result in surgical reconstruction. The choice of the 180-degree propeller flap was due to its ability to provide a good repair of the pressure ulcer and to pass over the ischiatic prominence in the patient in the forced decubitus position. The operatory course did not present any kind of complication. Using this reconstructive treatment, we have obtained complete coverage of the ischiatic pressure sore.

    Jae Yong Jeong, MD

    2014-06-01

    Full Text Available Summary: Performing secondary rhinoplasty in patients who underwent primary rhinoplasty using a silicone implant is difficult due to thinning of nasal skin and formation of a capsule. Excess capsule formation can cause capsular contracture, resulting in short nose deformity or implant deviation, migration, or implant demarcation. Revision rhinoplasty using a capsular flap, dorsal silicone implant, and tip plasty was performed in 95 Korean patients (91 women and 4 men; mean age, 27 years who previously underwent primary augmentation rhinoplasty using silicone implants. The capsular flap was composed by creating a dual plane above the anterior capsule and below the posterior capsule. The existing silicone implant was removed, and a new silicone implant was placed under the posterior capsule. The patients were followed up for 6 months to 4 years (mean, 31.7 months. Of the 95 patients who underwent secondary augmentation rhinoplasty using a capsular flap, 88 patients (92.6% showed satisfactory results. There was no hematoma or nasal skin vascular compromise. There was no visible or palpable capsule resorption or recurrent capsular contracture. Early implant malpositioning (within 30 days postoperatively was observed in 4 patients, and tip shape dissatisfaction (within 60 days postoperatively was reported by 3 patients. Four patients underwent revision surgery and had successful outcomes. Nasal augmentation using a silicone implant and capsular flap in secondary rhinoplasty avoids complications caused by removal of the capsule. Recurrent capsule formation or clinically noticeable resorption of the capsular flap was not observed in this study.

  1. Chronic Open Infective Lateral Malleolus Bursitis Management Using Local Rotational Flap

    Yong-Beom Lee

    2017-01-01

    Full Text Available Background. Using a sinus tarsi rotational flap is an uncommon approach to treating chronic open infective lateral malleolus bursitis. Methods. We treated eight patients, including six males, using this approach. First, we debrided all the infected tissues and used a negative pressure wound closure system where needed. After acute infection had been controlled, the local rotational flap was used for cases where the wound could not be closed by a simple suture or bone exposure. The rotational flap was detached with a curved skin incision at the sinus tarsi next to the open wound and sutured to the defect, paying careful attention to the superficial peroneal nerve. The donor site was managed with a split-thickness skin graft. Results. The patients’ mean age was 74.1 years. Six patients had a wound after suppurative infection, but two patients had ulcer-type bursitis. Six patients demonstrated full flap healing, but two patients had venous congestion necrosis. Conclusion. A sinus tarsi rotational flap is a useful method to ensure healing and coverage of chronic open lateral malleolus bursitis, especially for small to medium wounds with cavity and bone exposure.

    2017-08-01

    Full Text Available Objective: In this article, we present a personalized surgical technique to relocate a fascioperichondrial flap with a proximal base as an additional measure to improve results and hide sharp edges which frequently occur following traditional otoplasty. Materials and Methods: Fascioperichondrial flap with a proximal base prepared from the dorsal side was transposed to the anterior helix and conchal excision side and secured with stitches to hide visible edges and reinforce Furnas sutures. Nine patients operated for prominent ear deformity using this modification were included in the study and follow-up period was at least 6 months. Conchal mastoid distances were calculated from the superior and middle third of the ears before and after the operation, also in follow-up controls to determine the efficiency of the method. Results: There were no suture extrusions, skin necrosis or infection. The mean difference for both the upper and middle third of the ears were considerably lower (p≤0.05 at the end of six month after the operation. There were no visible skin edges and discomfort described by the patients. Conclusion: Fascioperichondrial flap with a proximal base repositioning to conchal side is an easy procedure that can be applied simply as an adjunct to traditional techniques. Addition of this flap provides an additional tissue to reinforce suture repair and, the results seem to be more durable and strong. Another main advantage of this flap is eliminating the unnatural visible breakpoints in the conchal bowl.

    Lichen sclerosus (LS) is a chronic inflammatory skin condition that frequently involves the anogenital region. Ongoing research is focused on finding more effective treatments for tissue repair and reducing symptoms. The aim of this study is to evaluate the effectiveness of platelet-rich plasma (PRP) local injections in penile LS. Forty-five male patients affected by penile LS underwent injections of autologous PRP in the affected skin areas. Age at diagnosis and at first treatment, number of treatments, clinical conditions (phimosis, splitting, inflammation, synechiae, meatus stenosis), symptoms (pain, burning, itching), and functional impairment were considered. Treatment efficacy was also evaluated through the Investigator's Global Assessment (IGA) on a six-point Likert scale and the Dermatology Life Quality Index (DLQI). The patient age at LS diagnosis was 36.20 ± 9.19 years, while the mean age at the first PRP treatment was 42.96 ± 11.32 years (p PRP injections, it was observed in all patients a significant improvement in clinical conditions, with reduction/disappearance of symptoms. Topical steroid therapy, interrupted before PRP treatment, was not restarted by any patient. Only one patient underwent a later circumcision procedure. Both IGA scale and DLQI score showed a significant difference (p PRP treatment. PRP treatment in penile LS seems to be helpful to regenerate scarring, reduce symptoms, and improve patient quality of life. Further studies are necessary to evaluate long-term results.

    2016-06-01

    Methods of free flap monitoring have become more sophisticated and expensive. This study aims to determine the cost of free flap monitoring and examine its cost effectiveness. We examined a group of patients who had had free flaps to the head and neck over a two-year period, and combined these results with costs obtained from business managers and staff. There were 132 free flaps with a success rate of 99%. The cost of monitoring was Aus $193/flap. Clinical monitoring during this time period cost Aus$25 476 and did not lead to the salvage of any free flaps. Cost equivalence is reached between monitoring and not monitoring only at a failure rate of 15.8%. This is to our knowledge the first study to calculate the cost of clinical monitoring of free flaps, and to examine its cost-effectiveness.

    2018-04-01

    The surgical management of pressure ulcers in the paraplegic or quadriplegic population is marked by the high risk of recurrence in the long-term. In the current era of perforator flaps, newer reconstructive options are available for the management of pressure ulcers, decreasing the need to use the classically described muscular or musculocutaneous locoregional flaps. The coverage of ischial sores described in this article by a pedicled flap based on a deep femoral artery perforator, appears to be an effective first-line reconstructive option for the management of limited size pressure ulcers. A number of fifteen paraplegic or quadriplegic patients having at least one ischial bed sore with underlying osteomyelitis were included in this series. The approximate location of the deep femoral artery perforator was initially identified using the "The Atlas of the perforator arteries of the skin, the trunk and limbs", which was confirmed, with the use of a Doppler device. A fasciocutaneous transposition flap was elevated, with the pivot point based on the cutaneous bridge centered on the perforator, and then transposed to cover the area of tissue loss. The donor site was closed primarily. A total of fifteen patients were operated from November 2015 to November 2016. The series comprised of 16 first presentations of a stage 4 pressure ulcers associated with underlying osteomyelitis that were subsequently reconstructed by the pedicled deep femoral artery perforator flap. The healing rate and functional results were both satisfactory. Fasciocutaneous flap reliable by deep femoral artery perforator appears to have a promising role in the treatment of ischial pressure sores. It is an attractive option to spare the use of musculocutaneous flaps in the area. Thus this flap could be used as a first-line option to cover ischial pressure ulcers of limited size.

    Vacuum-assisted closure (VAC) therapy has been shown to be effective at reducing bacterial counts in wounds until definitive bony coverage. However, there is continued debate over timing and type of definitive wound coverage even with VAC therapy application. From 2004 to 2009, 32 patients with Gustilo type IIIB open tibia fractures were initially treated with VAC therapy were included. The number of debridements, length of treatment with VAC dressing, definitive wound coverage management, and length of hospital stay, flap-related complications, and time to radiographic fracture healing were recorded. The mean Injury Severity Score was 17.3 ± 2.0. All wounds closed after being treated with the primary VAC closure. The mean interval between the initial injury and definitive intervention was 10.9 days ± 0.3 days. Twenty of 27 patients (74%) underwent rotational muscle flaps; four received free muscle flaps and three only with split-thickness skin grafts for definitive wound coverage. Nine of 32 patients (28%) underwent below knee amputation, five without flap coverage after several VAC sessions and four after definitive flap coverage. The average time to union was 10.0 months ± 2.0 months. Eight patients developed nonunion and 11 patients developed infections. The average follow-up time is 2.4 years ± 0.2 years. Patients were divided into two groups for analysis according to the interval time. The rate of infection was significantly increased in patients who had an interval of more than 7 days from the time of injury to flap coverage. The VAC therapy may help to reduce the flap size and need for a flap transfer for type IIIB open tibial fractures. However, prolonged periods of VAC usage, greater than 7 days, should be avoided to reduce higher infection and amputation risks.

While several types of flaps have been used in covering finger defects, all have limitations or disadvantages. The purpose of this study was to introduce our clinical experiences of using the lateral tarsal artery (LTA flap to successfully restore fingers after electrical injury.Patients and methods: From 2005 to 2012, 10 patients with 14 severe electrical burns to their fingers, including six thumbs and four index and four middle fingers, were treated with LTA flap. The wound size ranged from 2.0×3.0 cm to 3.5×5.0 cm. The flap with free tendon graft was used to repair the tendon defect in four cases, free nerve graft was used to repair the feeling defect in two cases, and the flap with nerve was used to repair the feeling defect in two cases. All the patients were followed up for 3 months to 2 years.Results: All skin flaps adhered successfully and there were no complications. All patients were satisfied with the esthetic appearance and functional outcome of the finger reconstruction.Conclusion: LTA flap is a reliable method to restore fingers after severe electrical injuries.

    At present, there is a strong interest in developing Micro Air Vehicles (MAV) for applications like disaster management and aerial surveys. At these small length scales, the flight of insects and small birds suggests that unsteady aerodynamics of flapping wings can offer many advantages over fixed wing flight, such as hovering-flight, high maneuverability and high lift at large angles of attack. Various lift generating mechanims such as delayed stall, wake capture and wing rotation contribute towards our understanding of insect flight. We address the effect of asymmetric flapping of wings on lift production. By visualising the flow around a pair of rectangular wings flapping in a water tank and numerically computing the flow using a discrete vortex method, we demonstrate that net lift can be produced by introducing an asymmetry in the upstroke-to-downstroke velocity profile of the flapping wings. The competition between generation of upstroke and downstroke tip vortices appears to hold the key to understanding this lift generation mechanism.

    We have evaluated the survival of dental implants placed in vascularised fibular flap onlay grafts placed over marginal mandibulectomies and the effects on marginal bone loss of different types of soft tissue around implants under functional loading. From 2001-2009 we studied a total of 11 patients (1 woman and10 men), three of whom had had ameloblastoma and eight who had had squamous cell carcinomas resected. A total of 38 dental implants were placed either at the time of transfer of the vascularised fibular ostoseptocutaneous flaps (nine patients with 30 implants) or secondarily (two patients with eight implants). Four patients were given palatal mucosal grafts to replace intraoral skin flaps around the dental implants (n=13), and the other seven had the skin flaps around the dental implants thinned (n=25) at the second stage of implantation of the osteointegrated teeth. All vascularised fibular osteoseptocutaneous flaps were successfully transferred, and all implants survived a mean (range) of 73 (33-113) months after occlusal functional loading. The mean (SD) marginal bone loss was 0.5 (0.3) mm on both mesial and distal sides in patients who had palatal mucosal grafts, but 1.8 (1.6) mm, and 1.7 (1.5) mm, respectively, on the mesial and distal sides in the patients who had had thinning of their skin flaps. This difference is significant (p=0.008) with less resorption of bone in the group who had palatal mucosal grafts. Palatal mucosa around the implants helps to reduce resorption of bone after functional loading of implants. Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons.

    Full Text Available Traumatic finger amputations are common, causing significant functional and cosmetic deficits. Microsurgical replantation techniques are the mainstay of treatment for most such injuries although they require adequate conservation of the amputated segment for a successful result. In distal finger amputations, replantation is the procedure of choice, as long as the amputated fragment is viable. If replantation is not an option, reposition + flap using a neurovascular flap can be an efficient option, as this offers improved skin coverage. To the best of our knowledge, this case illustrates the longest cold ischaemic time with a successful outcome.

    Two staged tissue expander-implant with acellular dermal matrix (TE/I + ADM) and deep inferior epigastric perforator (DIEP) flap are the most common implant and autologous methods of reconstruction in the U.S. Implant-based techniques are disproportionally more popular, partially due to its presumed cost effectiveness. We performed a comprehensive cost analysis to compare TE/I + ADM and DIEP flap. A comparative cost analysis of TE/I + ADM and DIEP flap was performed. Medicare reimbursement costs for each procedure and their associated complications were calculated. Pooled probabilities of complications including cellulitis, seroma, skin necrosis, implant removal, flap loss, partial flap loss, and fat necrosis, were calculated using published studies from 2010 to 2016. Average actual cost for successful TE/I + ADM and DIEP flap were $13 304.55 and $10 237.13, respectively. Incorporating pooled complication data from published literature resulted in an increase in cost to $13 963.46 for TE/I + ADM and $12 624.29 for DIEP flap. The expected costs for successful TE/I + ADM and DIEP flap were $9700.35 and $8644.23, which are lower than the actual costs. DIEP flap breast reconstruction incurs lower costs compared to TE/I + ADM. These costs are lower at baseline and when additional costs from pooled complications are incorporated. © 2017 Wiley Periodicals, Inc.

    Nowadays, the transposition of microvascular free flaps is the most popular method for management of head and neck defects. However, not all patients are suitable candidates for free flap reconstruction. In addition, not every defect requires a free flap transfer to achieve good functional results. The aim of this study was to assess whether pedicled flap reconstruction of head and neck defects is inferior to microvascular free flap reconstruction in terms of complications, functionality and prognosis. The records of consecutive patients who underwent free flap or pedicled flap reconstruction after head and neck cancer ablation from 2006 to 2015, from a single surgeon, in the AOUC Hospital, Florence Italy were analysed. A total of 93 patients, the majority with oral cancer (n = 59), were included, of which 64 were pedicled flap reconstructions (69%). The results showed no significant differences in terms of functional outcome, flap necrosis and complications in each type of reconstruction. Multivariate regression analysis of flap necrosis and functional impairments showed no associated factors. Multivariate regression analysis of complicated flap healing showed that only comorbidities remained an explaining factor (p = 0.019). Survival analysis and proportional hazard regression analysis regarding cancer relapse or distant metastasis, showed no significant differences in prognosis of patients concerning both types of reconstruction. In this retrospective, non-randomised study cohort, pedicled flaps were not significantly inferior to free flaps for reconstruction of head and neck defects, considering functionality, complications and prognosis. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    2014-10-01

    Full Text Available The ventral phalloplasty (VP has been well described in modern day penile prosthesis surgery. The main objectives of this maneuver are to increase perceived length and patient satisfaction and to counteract the natural 1-2 cm average loss in length when performing implantation of an inflatable penile prosthesis. Similarly, this video represents a new adaptation for partial penectomy patients. One can only hope that the addition of the VP for partial penectomy patients with good erectile function will increase their quality of life. The patient in this video is a 56-year-old male who presented with a 4.0x3.5x1.0 cm, pathologic stage T2 squamous cell carcinoma of the glans penis. After partial penectomy with VP and inguinal lymph node dissection, pathological specimen revealed negative margins, 3/5 right superficial nodes and 1/5 left superficial nodes positive for malignancy. The patient has been recommended post-operative systemic chemotherapy (with external beam radiotherapy based on the multiple node positivity and presence of extranodal extension. The patient’s pre-operative penile length was 9.5 cm, and after partial penectomy with VP, penile length is 7 cm.

    Despite introduction of oral phosphodiesterase type 5 inhibitors and intracavernosal vasoactive agents, penile prosthesis implant remains a relevant and desired option with sales of penile prostheses continue to stay high, as many men became refractory to medical therapy and/or seeking a more effective and permanent therapy. There are two types of penile prosthesis implants: inflatable and non-inflatable types, and the inflatable penile implants can be subdivided into single-, two- and three-piece devices. Non-inflatable penile prosthesis (non-IPP) may be referred to as semi-rigid rod or malleable prosthesis. IPP is considered a superior option to malleable prosthesis as it produces penile rigidity and flaccidity that closely replicates a normal penile erectile function. Since the introduction of IPP by Scott in 1973, surgical landscape for penile prosthesis implantation has changed dramatically. Advances in prosthesis design, device technologies and surgical techniques have made penile prosthesis implant a more natural, durable and reliable device. The following article reviews the scientific advances and technological innovation in modern penile prosthesis implants over the last four decades.

    Determining the ideal volume of the harvested flap to achieve symmetry in deep inferior epigastric artery perforator (DIEP) flap breast reconstructions is complex. With preoperative imaging techniques such as 3D stereophotogrammetry and computed tomography angiography (CTA) available nowadays, we can combine information to preoperatively plan the optimal flap volume to be harvested. In this proof-of-concept, we investigated whether projection of a virtual flap planning onto the patient's abdomen using a projection method could result in harvesting the correct flap volume. In six patients (n = 9 breasts), 3D stereophotogrammetry and CTA data were combined from which a virtual flap planning was created comprising perforator locations, blood vessel trajectory and flap size. All projected perforators were verified with Doppler ultrasound. Intraoperative flap measurements were collected to validate the determined flap delineation volume. The measured breast volume using 3D stereophotogrammetry was 578 ± 127 cc; on CTA images, 527 ± 106 cc flap volumes were planned. The nine harvested flaps weighed 533 ± 109 g resulting in a planned versus harvested flap mean difference of 5 ± 27 g (flap density 1.0 g/ml). In 41 out of 42 projected perforator locations, a Doppler signal was audible. This proof-of-concept shows in small numbers that flap volumes can be included into a virtual DIEP flap planning, and transferring the virtual planning to the patient through a projection method results in harvesting approximately the same volume during surgery. In our opinion, this innovative approach is the first step in consequently achieving symmetric breast volumes in DIEP flap breast reconstructions.

    Full Text Available Gingival recession in anterior teeth is a common concern due to esthetic reasons or root sensitivity. Gingival recession, especially in multiple anterior teeth, is of huge concern due to esthetic reasons. Various mucogingival surgeries are available for root coverage. This case report presents a new bridge flap technique, which allows the dentist not only to cover the previously denuded root surfaces but also to increase the zone of attached gingiva at a single step. In this case, a coronally advanced flap along with vestibular deepening technique was used as root coverage procedure for the treatment of multiple recession-type defect. Here, vestibular deepening technique is used to increase the width of the attached gingiva. The predictability of this procedure results in an esthetically healthy periodontium, along with gain in keratinized tissue and good patient′s acceptance.

    To investigate the effectiveness of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique for congenital buried penis. Between March 2010 and June 2012, 68 boys with congenital buried penis were treated by the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique, with a median age of 4 years and 10 months (range, 3 months-13 years). Of 68 cases, 14 were classified as phimosis type, 14 as rope belt type, 20 as moderate type, and 20 as severe type. The body of penis developed well and had no deformity. After operation, complications were observed, and the effectiveness was evaluated by the designed questionnaire. Early postoperative complications occurred in 11 cases, including obvious adhesion of the outside wrapping mouth in 4 cases, scrotal skin bloat in 5 cases, and distal foreskin necrosis in 2 cases; long-term complications occurred in 9 cases, including abdominal incision scar formation in 4 cases, wrapping mouth scar stricture in 3 cases, and short penis in 2 cases. Primary healing of incision was obtained in the other boys. Fifty-four cases were followed up 6-12 months (mean, 8 months). According to the designed questionnaire, satisfaction rate with the overall view in parents was 77.78% (42/54); the clinical improvement rate was 85.19% (46/54); exposure of the penis was satisfactory in parents of 50 cases; and the parents had no psychological burden of penis exposure in 46 cases, which were significantly improved when compared with preoperative ones (P penis exposure in 29 cases (53.70%) after operation, showing no significant difference when compared with preoperative one (18 cases, 33.33%) (chi2 = 1.22, P = 0.31). Application of the penile ventral scrotum cohesion place wedge cutting and improved Brisson technique can effectively correct congenital buried penis.

    A 79-year-old female with breast carcinoma undergoing a classical Halsted radical mastectomy followed by irradiation (total; 180 Gy) 20 years before developed a left anterior chest wall ulcer. The ulcer was 10.0 x 8.0 cm in size with osteolysis of 3rd, 4th and 5th ribs, exposed pericardium, and parietal pleura with a pleuro-cutaneous fistula. After thorough debridement, an omental pedicle flap was transposed onto the chest wall defect and subsequently covered using a split-skin graft. The omental pedicle flap was 90% effective in covering the pericardial defect and resulted in a complete closure of the pleuro-cutaneous fistula. This report emphasises that an omental pedicle flap is effective in the treatment of radio-necrosis of the chest wall and also stresses the importance of judging the extent of debridement of radio-necrotic tissue.

    Fonseca Aluizio G. da

    2003-01-01

    Full Text Available INTRODUCTION: The objective of this work is to describe a conservative surgical technique as an alternative to classic penile amputations, aiming the local control of the disease, in addition to trying to preserve the patient's sexual function. SURGICAL TECHNIQUE: After a circular incision of the skin around the penis, the subfascial plane is developed until the base of the organ. The dorsal neurovascular bundle and the urethra are isolated in their distal extremities. The neurovascular bundle is sectioned distally. A retrocoronal dissection plane is developed between the glans and the corpora cavernosa. When this stage is complete, the glans is fixed only to the urethra, which is distally sectioned as well. The neurovascular bundle is fixed to the dorsal albuginea. Following the spatulation of the urethra, a neomeatus is created using the overlay skin of the penis. Between January 2001 and July 2002, we employed this technique in 6 patients who had epidermoid carcinoma of the penis, which were limited to the glans, superficial, well or moderately differentiated and measuring up to 3 cm. COMMENTS: Several conservative surgical methods for treatment of carcinoma of the penis aim the organ's preservation, in an attempt of improving the quality of life of patients, however the indexes of local recurrence and failure in disease control are significant. The described technique showed to be safe and effective for disease control, in addition to preserving sexual function in all patients who were treated, representing, thus, a quite appealing conservative surgical alternative in selected cases.

    Conclusion: This method is somewhat complicated compared to reconstruction with a single flap, but it is a combination of standard local flaps and is a simple reconstructive procedure. By adding additional resection, the suture line is consistent with the border of the facial unit, so postoperative scarring is inconspicuous. This technique is aesthetically useful because of the continuity of colour and texture resulting from the use of adjacent flaps.

    In the past 130 years, the temporalis muscle flap has been used for a variety of different indications. In this age of microsurgery and perforator flaps, the temporalis muscle flap still has many useful applications for craniofacial reconstruction. Three hundred sixty-six temporalis muscle flaps were performed in a single center between 1978 and 2012. The authors divided the cases into two series-before and after 1994-because, after 1994, they started to perform free flap reconstructions, and indications for reconstruction with a temporalis muscle flap were changed RESULTS:: In the series after 1994, flaps were most commonly used for reconstruction of defects in the maxilla, mandible, and oropharynx, in addition to facial reanimation and filling of orbital defects. Complications included total flap necrosis (1.6 percent) and partial flap necrosis (10.7 percent). The rate of material extrusion at the donor site decreased after porous polyethylene was uniformly used for reconstruction from 17.1 to 7.9 percent. The pedicled temporalis muscle flap continues to have many applications in craniofacial reconstruction. With increasing use of free flaps, the authors' indications for the pedicled temporalis muscle flap are now restricted to (1) orbital filling for congenital or acquired anophthalmia; (2) filling of unilateral maxillectomy defects; and (3) facial reanimation in selected cases of facial nerve palsy.

    A 38-year-old man with history of repaired penile fracture presented with rapid detumescence, penile pain, and ecchymosis during vaginal sexual intercourse concerning for recurrent fracture. Surgical exploration revealed ruptured superficial dorsal vein of the penis, which was subsequently ligated. Patients with traumatic penile vascular injuries often present with clinical features indistinguishable from a true penile fracture. Gradual detumescence and an absence of characteristic popping sound may indicate a vascular injury but they cannot safely rule out a true penile fracture. Both true and false penile fractures require emergent surgical exploration and repair to prevent long-term complications. Copyright © 2016 Elsevier Inc. All rights reserved.

  15. Topology optimization of pressure adaptive honeycomb for a morphing flap

    Science.gov (United States)

    Vos, Roelof; Scheepstra, Jan; Barrett, Ron

    2011-03-01

    The paper begins with a brief historical overview of pressure adaptive materials and structures. By examining avian anatomy, it is seen that pressure-adaptive structures have been used successfully in the Natural world to hold structural positions for extended periods of time and yet allow for dynamic shape changes from one flight state to the next. More modern pneumatic actuators, including FAA certified autopilot servoactuators are frequently used by aircraft around the world. Pneumatic artificial muscles (PAM) show good promise as aircraft actuators, but follow the traditional model of load concentration and distribution commonly found in aircraft. A new system is proposed which leaves distributed loads distributed and manipulates structures through a distributed actuator. By using Pressure Adaptive Honeycomb (PAH), it is shown that large structural deformations in excess of 50% strains can be achieved while maintaining full structural integrity and enabling secondary flight control mechanisms like flaps. The successful implementation of pressure-adaptive honeycomb in the trailing edge of a wing section sparked the motivation for subsequent research into the optimal topology of the pressure adaptive honeycomb within the trailing edge of a morphing flap. As an input for the optimization two known shapes are required: a desired shape in cruise configuration and a desired shape in landing configuration. In addition, the boundary conditions and load cases (including aerodynamic loads and internal pressure loads) should be specified for each condition. Finally, a set of six design variables is specified relating to the honeycomb and upper skin topology of the morphing flap. A finite-element model of the pressure-adaptive honeycomb structure is developed specifically tailored to generate fast but reliable results for a given combination of external loading, input variables, and boundary conditions. Based on two bench tests it is shown that this model correlates well

    Reconstruction of complex tissue deficiencies in which each missing component is in a different spatial relationship to each other can be particularly challenging, especially in patients with limited recipient vessels. The chimera flap design is uniquely suited to reconstruct these deformities. Chimera flaps have been previously defined in many ways with 2 main categories: prefabricated or intrinsic. Herein we attempt to clarify the definition of a true intrinsic chimeric flap and provide examples of how these constructs provide a method for reconstruction of complex defects. The versatility of the intrinsic chimera flap and its procurement from 7 different vascular systems is described. A clarification of the definition of a true intrinsic chimera flap is described. In addition, construction of flaps from the lateral femoral circumflex, deep circumflex iliac, inferior gluteal, peroneal, subscapular, thoracodorsal, and radial arterial systems is described to showcase the versatility of these chimera flaps. A true intrinsic chimera flap must consist of more than a single tissue type. Each of the tissue components receives its blood flow from separate vascular branches or perforators that are connected to a single vascular source. These vascular branches must be of appropriate length to allow for insetting with 3-dimensional spatial freedom. There are a multitude of sites from which true intrinsic chimera flaps may be harvested.

    Swimming fish and flying insects use the flapping of fins and wings to generate thrust. In contrast, microscopic organisms typically deform their appendages in a wavelike fashion. Since a flapping motion with two degrees of freedom is able, in theory, to produce net forces from a time-periodic actuation at all Reynolds numbers, we compute in this paper the optimal flapping kinematics of a rigid spheroid in a Stokes flow. The hydrodynamics for the force generation and energetics of the flapping motion is solved exactly. We then compute analytically the gradient of a flapping efficiency in the space of all flapping gaits and employ it to derive numerically the optimal flapping kinematics as a function of the shape of the flapper and the amplitude of the motion. The kinematics of optimal flapping are observed to depend weakly on the flapper shape and are very similar to the figure-eight motion observed in the motion of insect wings. Our results suggest that flapping could be a exploited experimentally as a propulsion mechanism valid across the whole range of Reynolds numbers.

    Metastatic tumors of the penis originating from the gastrointestinal tract are rare clinical conditions. We experienced a case of penile metastasis in a 59-year-old man who underwent an abdomino-peritoneal resection for a moderately-differentiated adenocarcinoma of the rectum 4 years earlier. We report penile ultrasonography and magnetic resonance imaging findings on this uncommon metastatic penile tumor from a rectal adenocarcinoma and briefly review radiologic findings and relevant literature

    Although penile implantation remains a final solution for patients with refractory impotence, undesirable postoperative effects, including penile size reduction and cold sensation of the glans penis, remain problematic. We report results of a surgical method designed to avoid these problems. From 2003 to 2013, 35 consecutive patients received a malleable penile implant. Of these, 15 men (the enhancing group) were also treated with venous ligation of the retrocoronal venous plexus, deep dorsal...

    Full Text Available Objective: Most of the malignant cutaneous carcinomas are seen in the nasal region. Reconstruction of nasal defects is challenging because of the unique anatomic properties and complex structure of this region. In this study, we present our algorithm for the nasal skin defects that occurred after malignant skin tumor excisions. Material and Methods: Patients whose nasal skin was reconstructed after malignant skin tumor excision were included in the study. These patients were evaluated by their age, gender, comorbities, tumor location, tumor size, reconstruction type, histopathological diagnosis, and tumor recurrence. Results: A total of 130 patients (70 female, 60 male were evaluated. The average age of the patients was 67.8 years. Tumors were located mostly at the dorsum, alar reg
