    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 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.

    Although clinical examination alone or in combination with other techniques is the only ubiquitous method for flap monitoring, it becomes problematic with buried free-tissue transfer. We present a DIEP flap sentinel skin paddle (SSP) positioning algorithm and its reliability is also investigated using a standardized monitoring protocol. All DIEP flaps were monitored with hand-held Doppler examination and clinical observation beginning immediately after surgery in recovery room and continued postoperatively at the ward. Skin paddle (SP) position was preoperatively drawn following mastectomy type incisions; in skin-sparing mastectomies types I-III a small SP (sSP) replaces nipple-areola complex; in skin-sparing mastectomy type IV, SSP is positioned between wise-pattern branches while in type V between medial/lateral branches. In case of nipple-sparing mastectomy SSP is positioned at inframammary fold or in lateral/medial branches of omega/inverted omega incision if used. Three hundred forty-seven DIEP flap breast reconstructions were reviewed and stratified according to SP type into group A including 216 flaps with large SP and group B including 131 flaps with SSP and sSP. Sixteen flaps (4.6%) were taken back for pedicle compromise, 13 of which were salvaged (81.25%), 11 among 13 from group A and 2 among 3 from group B. There was no statistical difference between the groups concerning microvascular complication rate (P = 0.108), and time until take-back (P = 0.521) and flap salvage rate (P = 0.473) resulted independent of SP type. Our results suggest that early detection of perfusion impairment and successful flaps salvage could be achieved using SSP for buried DIEP flap monitoring, without adjunctive expensive monitoring tests.

    BACKGROUND It has been reported that systemic administration of allopurinol improves cell survival. This study was aimed to evaluate effects of allopurinol on skin flaps in dogs. METHODS Twenty dogs underwent one skin flap surgery with a 2-week interval. The first procedure was performed according to the standard protocols. The second phase was started by a 1-week pretreatment with allopurinol. Length of the necrotic zone was measured and recorded daily. At each phase, flaps were removed and sent for histopathological study after 1 week observation. RESULTS Mean length of the necrotic zone in allopurinol treated skin flaps has been significantly less than normal flaps over all 7 days of observation (p<0.0001). Histopathology study showed less inflammation and more normal tissue structure in the allopurinol treated skin flaps. CONCLUSION It was demonstrated that systemic administration of allopurinol significantly improved skin flap survival. PMID:28289614

    Introduction Mastectomy skin flap necrosis (MSFN) has a reported incidence of 5%–30% in the literature. It is often a significant and underappreciated problem. The aim of this article was to review the associated challenges and possible solutions. Methods A MEDLINE search was performed using the search term “mastectomy skin flap necrosis”. Titles and abstracts from peer-reviewed publications were screened for relevance. Results MSFN is a common complication and may present as partial- or full-thickness necrosis. Predictive patient risk factors include smoking, diabetes, obesity, radiotherapy, previous scars and severe medical comorbidity. MSFN leads to a number of challenges, including wound management problems, delays to adjuvant therapy, esthetic compromise, implant extrusion, patient distress and financial loss. Careful preoperative planning and meticulous surgical technique may reduce the incidence of MSFN. A number of intraoperative techniques are available to try and predict skin flaps at risk of MSFN. MSFN may be managed operatively or nonoperatively. Early intervention may reduce the morbidity of MSFN in selected cases. Topical nitroglycerin ointment may be beneficial in reducing MSFN following immediate reconstruction, but the evidence base is still limited. Conclusion MSFN can result in considerable challenges for the patient and the health care service. This review discusses the management options for this problem. PMID:28331365

    In reconstructive surgery, occasional free flap failures occur despite the clinical and technical advances in microsurgery of the past few years. To minimize these losses a better understanding of basic flap physiology must be achieved. The objectives of this work were the investigation of the haemodynamic characteristics of skin and muscle flaps in normal and compromised circumstances, the viability of skin and muscle flaps after pedicle ligation or ischaemia, and the possible interrelationship of haemodynamics and viability. A Wistar rat groin island skin flap model was used to assess flap survival following vascular compromise produced by vessel ligation. Survival was seen earliest following loss of the artery and was not dependent on circulation through the vascular pedicle after 5 days. A study using free groin flaps in rats gave similar results. Normal free groin flaps were then transferred to irradiated Fischer F344 rats. Delayed neovascularization was shown at a time corresponding to the onset of the late phase of the response to skin radiation. A canine inferior epigastric free skin flap model was established to determine the normal haemodynamic parameters during free flap transfer. A canine gracilis free muscle flap model was developed. Normal haemodynamic parameters are given. These parameters were examined after ischaemia. Survival of the muscle followed ischaemia of 4 hours or less. Flap survival is not dependent solely on arterial input or venous drainage. More complex phenomena such as the reactive hyperaemia following ischaemia are implicated in survival.

    Several animal models of skin flap construction were reported using biomaterials in a way similar to prefabrication. However, there are few animal model using biomaterials similar to prelamination, another main way of clinical skin flap construction that has been proved to be reliable. Can biomaterials be added in skin flap prelamination to reduce the use of autogenous tissues? Beside individual clinical attempts, animal model is needed for randomized controlled trial to objectively evaluate the feasibility and further investigation. Combining human Acellular Dermal Matrix (hADM) and autologous skin graft, we prelaminated flaps based on inguinal fascia. One, two, three and four weeks later, hADM exhibited a sound revascularization and host cell infiltration. Prelaminated skin flaps were then raised and microsurgically transplanted back to groin region. Except for flaps after one week of prelamination, flaps from other subgroups successfully reconstructed defects. After six to sixteen weeks of transplantation, hADM was proved to being able to maintain its original structure, having a wealth of host tissue cells and achieving full revascularization.To our knowledge, this is the first animal model of prelaminating skin flap with biomaterials. Success of this animal model indicates that novel flap prelamination with biomaterials is feasible.

    The aim of this article is to report the application of expanding retroauricular skin fascia flap, and autogenous costal cartilage for congenital microtia reconstruction. Microtia reconstruction was generally completed in 3 surgical stages. In the first surgical stage, a 50 or 80 mL kidney-shaped tissue expander was inserted subcutaneously in the retroauricular mastoid region. Inflation of saline volume increased up to 60 to 80 mL, and skin flap was expanded for 2 to 3 months postoperatively. In the second surgical stage, removal of tissue expander, formation of retroauricular skin flap, elevation of retroauricular fascia flap, and pedicles of both flaps in remnant ear side were performed. Costal cartilage was harvested from ipsilateral side chest to the ear for reconstruction. The 3D ear framework was sculpted with stabilization of structure, contour and erection. Simultaneously, intermediate full thickness skin graft of 4 x 8 cm was obtained from previous incision site from where costal cartilage was harvested. Cartilage ear framework was anchored between skin flap and fascia flap, and fixed it symmetrically to the opposite normal ear, inferior portion of the ear framework was wrapped by remnant ear lobule, expanded skin flap covered the anterior portion of the framework, fascial flap was draped to the posterior side of framework and helical rim, then fascial flap was surfaced by intermediate full thickness skin graft. Suction drain was inserted and coated between skin flap and framework, drain was removed fifth postoperative day. Tragus construction and conchal excavation with skin graft was performed in the third stage of microtia reconstruction. Between October 2000 and October 2007, 426 cases were diagnosed as unilateral microtia patients and 22 cases were bilateral microtia patients. Therefore, 448 microtia ears were treated with tissue expander and autogenous costal cartilage. In 262 cases, structure of the helix, tragus, conchal excavation

    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.

    Before visiting a plastic surgeon, some microtia patients may undergo canaloplasty for hearing improvement. In such cases, scarred tissues and the reconstructed external auditory canal in the postauricular area may cause a significant limitation in using the posterior auricular skin flap for ear reconstruction. In this article, we present a new method for auricular reconstruction in microtia patients with previous canaloplasty. By dividing a postauricular skin flap into an upper scalp extended skin flap and a lower mastoid extended skin flap at the level of a reconstructed external auditory canal, the entire anterior surface of the auricular framework can be covered with the two extended postauricular skin flaps. The reconstructed ear shows good color match and texture, with the entire anterior surface of the reconstructed ear being resurfaced with the skin flaps. Clinical question/level of evidence; therapeutic level IV.

    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

    Background: Although there are many surgical treatments for covering the skin defect of the fore–mid foot, how to reconstruct the weight-bearing region remains a challenge. The weight-bearing region of the sole needs to withstand the pressure and shearing stresses of walking, so the plantar skin is anatomically different from other skins in the areas of texture, thickness, subcutaneous tissue, etc. Medial plantar flaps that are harvested from the instep region are regarded as the first choice for weight-bearing region reconstruction because of their excellent functional and aesthetic long-term result. However, when facing an extensive skin defect on a weight-bearing area such as a fore–mid foot avulsion, the application of this flap is limited because if we put the flap in a weight-bearing area of the forefoot, the set of vessels will be exposed to outside. Methods: We suggest 2 connected free flaps (posterior tibial artery flap and medial plantar flap) pedicled with 1 set of vessels. The medial plantar flap was used to cover the skin defect of the weight-bearing area in the forefoot. The dorsal skin defect of the injured foot was covered with a posterior tibial artery flap and supplied the medial plantar flap with the posterior tibial vessel. The midfoot skin defect was repaired by a full-skin grafting. Results: Long-term follow-up results showed that the shape and function of the injured limbs recovered almost entirely. Conclusion: This method of connected flaps is suitable for repairing large skin defects of the fore–mid foot. PMID:27975013

    Full Text Available Introduction: Numerous pharmacological agents have been used to enhance the viability of flaps. Ischemia reperfusion (I/R injury is an unwanted, sometimes devastating complication in reconstructive microsurgery. Tadalafil, a specific inhibitor of phosphodiesterase type 5 is mainly used for erectile dysfunction, and acts on vascular smooth muscles, platelets and leukocytes. Herein, the protective and therapeutical effect of tadalafil in I/R injury in rat skin flap model is evaluated. Materials and Methods: Sixty epigastric island flaps were used to create I/R model in 60 Wistar rats (non-ischemic group, ischemic group, medication group. Biochemical markers including total nitrite, malondialdehyde (MDA and myeloperoxidase (MPO were analysed. Necrosis rates were calculated and histopathologic evaluation was carried out. Results: MDA, MPO and total nitrite values were found elevated in the ischemic group, however there was an evident drop in the medication group. Histological results revealed that early inflammatory findings (oedema, neutrophil infiltration, necrosis rate were observed lower with tadalafil administration. Moreover, statistical significance (P < 0.05 was recorded. Conclusions: We conclude that tadalafil has beneficial effects on epigastric island flaps against I/R injury.

    Full Text Available Purpose. To compare the outcomes of external dacryocystorhinostomy (E-DCR by using two different flap anastomosis patterns and skin incision types. Methods. This study included 79 patients (88 eyes with lacrimal drainage system disorders who underwent E-DCR surgery. Fifty eyes of 44 patients (group A underwent E-DCR by suturing anterior and posterior flaps (H-flap of the lacrimal sac with curvilinear skin incision whereas in 38 eyes of 35 patients (group B DCR was performed by suturing only anterior flaps (U-flap with W skin incision. Results. The success rate was evaluated according to lacrimal patency and scar assessment scores. Patency was achieved in 78 patients (88.6%. In terms of groups, patency was 44 eyes (88.0% in group A and 34 eyes (89.5% in group B. There was no statistically significant difference in the success rates of lacrimal patency between the two groups. Further, there was no statistically significant difference concerning cutaneous scar scores. Conclusion. Our study suggests that anastomoses of only anterior flaps or both anterior and posterior flaps have similar success rates; suturing only anterior flaps is easier to perform and shortens the operative time. In addition, W skin incision is a reasonable alternative to curvilinear incision for reducing scar formation.

    Skin flap necrosis is a problem encountered postoperatively. The purpose of this study was to evaluate the effects of platelet-rich plasma containing fragmin/protamine microparticles (PRP&F/P MPs) on viability in a rat dorsal paired pedicle skin (DPPS) flap. Two symmetrical adjoining rectangular flaps (8 × 2 cm each) were drawn on the rat dorsum. Two days after PRP&F/P MPs-, PRP-, F/P MPs-, and saline (control)-injections (n = 8 each), flaps were elevated as a random pattern flap without the lateral thoracic, posterior intercostal, and deep circumflex iliac vessels. The flaps were immediately sutured back and the flap survival area was measured 7 d after flap elevation. The flap survival rate in PRP&F/P MPs-injected groups (73.1% ± 4.2%) was significantly higher than those in PRP (64.9% ± 4.0%), F/P MPs (59.4 ± 4.5%), and control (61.2% ± 4.2%) groups. Histologic observation of the flaps showed survived thick granulation tissue and neovascularization in PRP&F/P MPs-injected groups. When PRP&F/P MPs are administered 2 d before the flap elevation, the improved flap survivals are observed. The pre-injection of PRP&F/P MPs may thus represent a promising treatment to prevent skin flap necrosis in reconstructive surgery. Copyright © 2011 Elsevier Inc. All rights reserved.

    Conclusions: dASCs could improve flap reinnervation by 2 mechanisms: First, neurotrophic factors produced by dASCs facilitated regrowth of cutaneous axons from the surroundings of flap. Second, nerve growth factor released by dASCs induced the collateral sprouting of undamaged axons in adjacent tissues. In addition to the use of innervated flaps, dASC transplantation therapy could be a new approach to improve the sensory recovery of skin flaps.

  2. Cannula-Assisted Flap Elevation (CAFE): a novel technique for developing flaps during skin-sparing mastectomies.

    2015-02-01

    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.

    The objective of this study was to compare two noninvasive techniques, laser Doppler and optical spectroscopy, for monitoring hemodynamic changes in skin flaps. Animal models for assessing these changes in microvascular free flaps and pedicle flaps were investigated. A 2 x 3-cm free flap model based on the epigastric vein-artery pair and a reversed MacFarlane 3 x 10-cm pedicle flap model were used in this study. Animals were divided into four groups, with groups 1 (n = 6) and 2 (n = 4) undergoing epigastric free flap surgery and groups 3 (n = 3) and 4 (n = 10) undergoing pedicle flap surgery. Groups 1 and 4 served as controls for each of the flap models. Groups 2 and 3 served as ischemia-reperfusion models. Optical spectroscopy provides a measure of hemoglobin oxygen saturation and blood volume, and the laser Doppler method measures blood flow. Optical spectroscopy proved to be consistently more reliable in detecting problems with arterial in flow compared with laser Doppler assessments. When spectroscopy was used in an imaging configuration, oxygen saturation images of the entire flap were generated, thus creating a visual picture of global flap health. In both single-point and imaging modes the technique was sensitive to vessel manipulation, with the immediate post operative images providing an accurate prediction of eventual outcome. This series of skin flap studies suggests a potential role for optical spectroscopy and spectroscopic imaging in the clinical assessment of skin flaps.

    The use of skin flaps in reconstructive surgery is the first-line surgical treatment for the reconstruction of skin defects and is essentially considered the starting point of plastic surgery. Despite their excellent usability, their application includes general surgical risks or possible complications, the primary and most common is necrosis of the flap. To improve flap survival, researchers have used different methods, including the use of adipose-derived stem cells, with significant positive results. In our research we will report the use of adipose-derived stem cells in pedicle skin flap survival based on current literature on various experimental models in animals.

    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.

    Although the fibula free flap (FFF) is a useful choice for mandible reconstruction, its application for large oromandibular defects is still debated upon. We report the use of FFF with a bilobed perforator-based skin paddle for combined hemiglossectomy, floor-of-the-mouth, tonsillar pillar, and mandibular body defect. A case of an 84-year-old woman with a 2.5 × 3.5-cm exophytic ulcerated mass on the right side of the tongue, extended to omolateral gengival fornix, tonsillar pillar, and mandibular body, is reported. An osteocutaneus FFF with a 7-cm bone strut and a 17 × 10-cm bilobed shaped skin paddle was performed. The longer lobe was used to restore tongue shape, whereas the smaller lobe was used to line the pelvic floor, gingival, and tonsillar pillar. The postoperative period was uneventful. The patient was capable to protrude her neotongue beyond the virtual incisors line and to touch the hard palate at different degrees of mouth opening. The bilobed perforator-based skin paddle FFF is felt to be a sound option for large compound oromandibular defects offering the possibility to safely base the skin component on a single peroneal perforator while achieving effective tongue mobility preservation.

    Full Text Available OBJECTIVE: This study investigated the effects of buflomedil and pentoxifylline, both of which are used in reconstructive surgery of hamster skin flap microcirculation, and evaluated the skin flap survival rate by orthogonal polarization spectral imaging. METHOD: Twenty-four adult male Syrian golden hamsters were divided into three groups: a control (C, 0.1 ml 0.9% saline, buflomedil (B, 3 mg/kg/day, and pentoxifylline group (P, 14.5 mg/kg/day. Treatments administered intraperitoneally were initiated 1 hour before skin flap preparation and continued for 7 days post-operatively at 12-hour intervals. Preparations (skin flaps were divided into 12 fields, which were organized into six bands. Functional capillary density (FCD, in mm/mm², distance from the skin flap base to blood flow cessation (Dist with flow, in cm, percentage of viable skin (VA, in%, and qualitative analysis of blood flow by orthogonal polarization spectral imaging were performed at 1 and 24 hours and on the seventh post-operative day. RESULT: Bands IV, V, and VI presented no flow independent of time. The functional capillary density group B was higher than that of groups C and P, primarily after 24 hours. All groups showed an increase in D with time but reached similar final distances (C = 2.73, B = 2.78 and P = 2.70 cm. Moreover, the percentage of viable areas remained at approximately 50%. The orthogonal polarization spectral imaging was useful to assess viability by counting fields with and without blood flow. CONCLUSIONS: Functional capillary density values were higher in the buflomedil group compared to the control and pentoxifylline groups in this model. Functional capillary density did not influence D or the percentage of VA, and the technique showed favorable potential to assess/predict the viability of skin flaps within 1 h after surgery.

    The experiment was designed to compare the effect of intraoperative platelet-rich plasma (PRP) and fibrin glue application on skin flap survival. In this study, bilateral epigastric flaps were elevated in 24 rats. The right-side flaps were used as the control of the left-side flaps. Platelet-rich plasma, fibrin glue, and thrombin had been applied under the flap sites in groups 1, 2, and 3, respectively. Five days later, all flap pedicles were ligated. Necrotic area measurements, microangiography, and histologic and immunohistochemical evaluations were performed to compare the groups. Platelet-rich plasma reduced necrotic area percentages as compared with other groups. Histologically and microangiographically increased number of arterioles were observed in PRP groups. Thrombin when used alone increased flap necrosis. Vascular endothelial growth factor, platelet-derived growth factor, and transforming growth factor β3 primary antibody staining showed increased neovascularization and reepithelialization in all PRP-applied flaps. This study demonstrated that PRP, when applied intraoperatively under the skin flap, may enhance flap survival. Thrombin used alone was found to be unsuitable in flap surgery.

    Improving survival of skin flaps used in soft-tissue reconstruction is clinically an important goal, and several systemic and local agents have been used for this purpose. However, a substance that prevents the flap necrosis has not yet been defined. This study aimed to investigate whether a Rosmarinus officinalis extract could improve the skin flap survival. In this study, 21 Wistar albino rats were divided into three groups. Rectangular 8 × 2 cm random-pattern flaps were elevated from the back of the rats. Group I was considered the control group. In Group II, a 0.5-cc of Rosmarinus officinalis oil was applied with an ear bud to the flap area 30 minutes before the flap elevation. After suturing the flaps to their location, the oil was administered twice a day for a week. In Group III, 0.5 cc of the oil was applied twice a day to the area that was elevated for a week until surgery. At the end of the week, the flaps were sutured to their location, and wiped postoperatively twice a day for a week with the oil. Mean percentage of these areas was found to be 29.81%, 58.99%, and 67.68% in Group I, Group II, and Group III, respectively. The mean percentage of the flap survival areas and vessel diameters were significantly greater in the Groups II and III than in the control group (p Rosmarinus officinalis extract can increase the flap survivability.

    SUMMARY: In reconstructive surgery defects are closed using pedicled or free flaps. By raising these flaps the reconstructive surgeon creates new defects, which in turn are closed primarily or with the use of skin grafts. Inevitably, this results in extra scars that may be visible and may also lead

    Reconstruction of large defects of the lateral region of the face is rather challenging due to the unique color, texture, and thickness of soft tissues in this area. Microsurgical free flaps represent the gold standard, providing superior functional and aesthetic restoration. Purpose of this study was to assess reliability of skin-grafted latissimus dorsi (LD) flap, for a pleasant and symmetric reconstruction of the lateral aesthetic units of the face compared to a control group of patients addressed to perforator flaps. From November 2008 to June 2012, 5 patients underwent skin-grafted LD flap reconstruction of defects involving the lateral aesthetic units of the face, with 8.1 ± 0.5 × 9.7 ± 1.3 cm mean size. A 1-to-4 Likert scale was used to assess skin color, texture, shape, and bulkiness. Using the Pressure-Specified Sensory Device epicritic, proprioceptive, and protopathic sensitivities were tested. Outcomes were compared with those of a control group of 5 patients addressed to reconstruction with perforator flaps (3 anterolateral thigh flap, 2 vertical deep inferior perforator flap). At mean 21-month follow-up all flaps healed uneventfully without need for revisions, all developing more satisfactory results in terms of skin color (P = 0.028) and texture (P = 0.021) match, shape (P = 0.047) and bulkiness (P = 0.012) compared with perforator flaps. No differences in epicritic, proprioceptive, and protopathic sensitivities were observed (P > 0.05) between the two groups. Skin-grafted LD flap may be a suitable option for reconstruction of wide defects of the lateral aesthetic units of the face.

    With increasing use of immediate breast reconstruction (IBR), mastectomy skin flap necrosis (MSFN) is a clinical problem that deserves further study. We propose a validated scoring system to discriminate MSFN severity and standardize its assessment. Women who underwent skin-sparing (SSM) or nipple-sparing mastectomy (NSM) and IBR from November 2009 to October 2010 were studied retrospectively. A workgroup of breast and plastic surgeons scored postoperative photographs using the skin ischemia necrosis (SKIN) score to assess depth and surface area of MSFN. We evaluated correlation of the SKIN score with reoperation for MSFN and its reproducibility in an external sample of surgeons. We identified 106 subjects (175 operated breasts: 103 SSM, 72 NSM) who had ≥1 postoperative photograph within 60 days. SKIN scores correlated strongly with need for reoperation for MSFN, with an AUC of 0.96 for SSM and 0.89 for NSM. External scores agreed well with the gold standard scores for the breast mound photographs with weighted kappa values of 0.82 (depth), 0.56 (surface area), and 0.79 (composite score). The agreement was similar for the nipple-areolar complex photographs: 0.75 (depth), 0.63 (surface area), and 0.79 (composite score). A simple scoring system to assess the severity of MSFN is proposed, incorporating both depth and surface area of MSFN. The SKIN score correlates strongly with the need for reoperation to manage MSFN and is reproducible among breast and plastic surgeons.

    Mesenchymal stem cells(MSCs), multipotential cells that reside within the bone marrow, can be induced to differentiate into various cells, such as osteoblasts, adipocytes, chondrocytes, vascular endothelial progenitor cells, and other cell types. MSCs are being widely studied as potential cell therapy agents due to their angiogenic properties, which have been well established by in vitro and in vivo researches. Within this context, MSCs therapy appears to hold substantial promise, particularly in the treatment of conditions involving skin grafts, pedicle flaps, as well as free flaps described in literatures. The purpose of this review is to report the new advances and mechanisms underlying MSCs therapy against skin flaps necrosis.

    Background Hyperbaric oxygen preconditioning (HBO) is a new method of ischemia preconditioning.In this study,we examined its effects on skin flap survival and the mechanisms involved.Methods Thirty-six rats were divided into three groups:HBO preconditioning,control,and sham groups.An extended epigastric adipocutaneous flap based on the right superficial epigastric artery and vein was raised.A 3-hour period of flap ischemia was induced by clamping the pedicle vessels with a microvascular clamp.At the end of ischemia induction,the clamp was removed and the flap was resutured.Rats in the HBO preconditioning group were treated with HBO four times before surgery.Microcirculation in the skin flap was measured on postoperative days 1,3 and 5.The size of the flap was measured on postoperative day 5,before the animals were sacrificed.Samples of the skin flap were prepared and stained with hematoxylin and eosin.The levels of tumor necrosis factor (TNF)-o,interleukin (IL)-1β,and IL-6 in the flap samples were measured.Results Surviving flap size was significantly higher in the HBO preconditioning group compared with controls,with a reduced inflammatory response and increased perfusion.IL-1,TNF-α,and IL-6 levels in the HBO preconditioning group were lower than in controls.Conclusions HBO preconditioning improved flap survival in this ischemia-reperfusion rat model.The mechanisms responsible for this effect may relate to attenuation of the inflammatory response and increased flap perfusion following HBO preconditioning.

    Intermittent parathyroid hormone (PTH) administration increases systemic and craniofacial bone mass. However, the effect of PTH therapy on healing of tooth extraction sites is unknown. The aims of this study were to determine the effect of PTH therapy on tooth extraction socket healing and to examine whether PTH intra-oral injection promotes healing. The mandibular first molars were extracted in rats, and subcutaneous PTH was administered intermittently for 7, 14, and 28 days. In a second study, maxillary second molars were extracted, and PTH was administered by either subcutaneous or intra-oral injection to determine the efficacy of intra-oral PTH administration. Healing was assessed by micro-computed tomography and histomorphometric analyses. PTH therapy accelerated the entire healing process and promoted both hard- and soft-tissue healing by increasing bone fill and connective tissue maturation. PTH therapy by intra-oral injection was as effective as subcutaneous injection in promoting tooth extraction socket healing. The findings suggest that PTH therapy promotes tooth extraction socket healing and that intra-oral injections can be used to administer PTH.

    We evaluated the current application of Duckett paraexstrophy skin flaps for bladder exstrophy reconstruction. We reviewed the records of cases of classic exstrophy treated at our institution between September 1993 and March 2007. A total of 21 patients were identified in whom modified Duckett paraexstrophy skin flaps were used in bladder closure at our institution. Another 12 patients were referred during the same time after closure with complications with flap use. Of the 21 patients who underwent closure at our institution with our modified version of the Duckett flaps 1 (4%) had a complication, that is urethral stricture. This responded to internal urethrotomy and daily intermittent catheterization for 4 months, and the stricture stabilized. Four of the 12 referred patients responded to multiple urethral dilations, 3 underwent open repair with a buccal graft, 2 received a full-thickness skin graft and 3 underwent internal urethrotomy with daily intermittent catheterization for 4 months. Of our 21 patients with internal treatment 14 underwent bladder neck repair, 5 underwent epispadias repair and 2 were awaiting further reconstruction. Six of the 12 referred patients underwent bladder neck repair, 4 underwent epispadias repair and 2 were awaiting further reconstruction. By modifying our version of the Duckett paraexstrophy skin flaps we have lowered our complication rate significantly. While overall use of these flaps has continued to decrease, when they are required, these modifications help avoid complicating strictures and their sequelae in the bladder and upper urinary tract.

    In the present study, we evaluated the efficacy of flaps via measurement of galvanic skin responses (GSR) in patients who had undergone superficial parotidectomy either with or without sternocleidomastoid (SCM) muscle flaps. Retrospective study design was used. The setting included University of Uludag School of Medicine Department of Otorhinolaryngology. Eleven patients who had undergone superficial parotidectomy for benign diseases in our clinic between June 2003 and August 2006 were included in the study. SCM muscle flaps were used in four patients. The GSR of the patients were measured using a MP 30 System. The Mann-Whitney U test was used for the analysis of data. There were complaints that resembled Frey's syndrome in three patients in whom flaps had not been performed. Patients with flaps had no complaints. In patients with flaps, no significant GSR changes were observed between the control and operated sides (P > 0.05). In patients without flaps, the GSR levels were significantly higher on the operated side compared to the control side (P SCM flap is an efficient method by which to prevent Frey's syndrome, and the GSR test is beneficial both in diagnosiing and determining the severity of the disease as well as evaluating the efficacy of surgical techniques used to prevent Frey's syndrome.

    Reconstruction of the through-and-through defects of the oral cavity, involving oral mucosa, bone, and external skin is a major challenge. A single fibula osteocutaneous flap providing two skin islands is an option for such composite reconstruction. The number, location, and size of skin perforators were studied in the distal two thirds of the lower legs in 22 cases of fibula osteocutaneous flap mandibular reconstruction, and whether the skin paddle of the fibula flap could always be divided completely based on two distal perforators was examined. In this study, only 50% of the flaps had two or more distal perforators; thus, it was concluded that the skin paddle of the fibula osteocutaneous flap could not always be divided based on two distal skin perforators.

    We used a platysma skin flap to repair larynx and hypopharynx defects to improve postoperative laryngeal function in patients with pyriform fossa cancer. Larynx-sparing surgery and postoperative radiotherapy were used in 10 patients with pyriform fossa cancer. The surgical approaches of lymph node dissection of the neck, vertical partial laryngectomy, and pyriform fossa resection were adopted, and a platysma skin flap was used to repair the resulting defects. In this group, the overall 3-year survival rate was 75% according to the Kaplan-Meier analysis, and the local control rate was 90%. Additionally, all patients were able to speak fluently with mild-to-moderate hoarseness. The tracheal tube was removed in all cases. Laryngeal fistulas were observed in 1 patient during radiotherapy. In conclusion, a platysma skin flap can be used to rebuild the larynx and hypopharynx in larynx-sparing resection for pyriform fossa cancer. These patients can obtain good postoperative function in swallowing, breathing, and pronunciation.

    This study was conducted to determine the effects of skin-flap undermining and superficial musculoaponeurotic system (SMAS) suspension on wound-closing tension. Nine sides from five fresh-frozen cadavers were used, with closing tension measured at the two main anchor points, anteriorly (A) and posteriorly (P), with and without SMAS plication for minimal (MIN), intermediate (INT), and maximal (MAX) skin-flap undermining. Results indicated that closing tension was significantly decreased with SMAS plication, both A and P, for all three levels of skin undermining. The average decrease in closing tension with SMAS plication was: A-MIN 191 g, A-INT 95 g, A-MAX 83 g, P-MIN 235 g, P-INT 68 g, and P-MAX 70 g (P tension decreased with wider skin-flap undermining, both with and without SMAS plication. The tension-reducing effect of SMAS plication was decreased with wider skin-flap undermining. Regression analysis determined a second-order exponential curve relating closing tension to skin excision.

    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.

    To investigate the clinical application of the modified bilobed flap in the reconstruction of zygomatic-facial massive defect after resection of skin cancer. Between August 2009 and October 2011, 15 patients with skin cancer in the zygomatic-facial region underwent defect reconstruction using modified bilobed flaps after surgical removal. There were 12 males and 3 females, aged 52-78 years (mean, 64.1 years). The disease duration was 1-14 months (mean, 4.6 months). Among the patients, there were 11 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma; 1 patient had infection and the others had no skin ulceration; and tumor involved the skin layer in all patients. According to TNM staging, 13 cases were rated as T2N0M2 and 2 cases as T3N0M3. The defect size ranged from 4.0 cm x 2.5 cm to 6.5 cm x 4.0 cm after cancer resection. The modified bilobed flaps consisting of pre-auricular flap and post-auricular flap was used to repair the defect after cancer resection. The size ranged from 4.0 cm x 2.5 cm to 6.5 cm x 4.0 cm of the first flap and from 3.0 cm x 2.0 cm to 5.0 cm x 3.0 cm of the second flap. Partial incision dehiscence occurred in 1 case, and was cured after dressing change; the flaps survived and incision healed primarily in the other cases. Fourteen patients were followed up 12-24 months (mean, 18.7 months). No recurrence was found, and the patients had no obvious face asymmetry or skin scar with normal closure of eyelid and facial nerve function. At last follow-up, the results were very satisfactory in 5 cases, satisfactory in 7 cases, generally satisfactory in 1 case, and dissatisfactory in 1 case. The pre- and post-auricular bilobed flaps could be used to reconstruct the massive defects in the zygomatic-facial region after resection of skin cancer.

    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.

    Summary Background Currently about 70% of women who suffer from breast cancer undergo breast-conserving therapy (BCT) without removing the entire breast. Thus, this surgical approach is the standard therapy for primary breast cancer. If corrections are necessary, the breast surgeon is faced with irritated skin and higher risks of complications in wound healing. After radiation, an implant-based reconstruction is only recommended in selected cases. Correction of a poor BCT outcome is often only solved with an additional extended operation using autologous reconstruction. Material/Methods In our plastic surgery unit, which focuses on breast reconstruction, we offer a skin-sparing or subcutaneous mastectomy, followed by primary breast reconstruction based on free autologous tissue transfer to correct poor BCT outcomes. Between July 2004 and May 2011 we performed 1068 deep inferior epigastric artery perforator (DIEP) flaps for breast reconstruction, including 64 skin-sparing or subcutaneous mastectomies, followed by primary DIEP breast reconstruction procedures after BCT procedures. Results In all free flap-based breast reconstruction procedures, we had a total flap loss in 0.8% (9 cases). Within the group of patients after BCT, we performed 41 DIEP flaps and 23 ms-2 TRAM flaps after skin-sparing or subcutaneous mastectomies to reconstruct the breast. Among this group we had of a total flap loss in 1.6% (1 case). Conclusions In cases of large tumour sizes and/or difficult tumour locations, the initial oncologic breast surgeon should inform the patients of a possibly poor cosmetic result after BCT and radiation. In our opinion a skin-sparing mastectomy with primary breast reconstruction should be discussed as a valid alternative. PMID:23197233

    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.

    Ischemic skin flap necrosis can occur in random pattern flaps. An excess amount of reactive oxygen species is generated and causes necrosis in the ischemic tissue. Nitrosonifedipine (NO-NIF) has been demonstrated to possess potent radical scavenging ability. However, there has been no study on the effects of NO-NIF on ischemic skin flap necrosis. Therefore, they evaluated the potential of NO-NIF in ameliorating ischemic skin flap necrosis in a mouse model. A random pattern skin flap (1.0 × 3.0 cm) was elevated on the dorsum of C57BL/6 mice. NO-NIF was administered by topical injection immediately after surgery and every 24 hours thereafter. Flap survival was evaluated on postoperative day 7. Tissue samples from the skin flaps were harvested on postoperative days 1 and 3 to analyze oxidative stress, apoptosis and endothelial dysfunction. The viable area of the flap in the NO-NIF group was significantly increased (78.30 ± 7.041%) compared with that of the control group (47.77 ± 6.549%, p NIF reduced oxidative stress, apoptosis and endothelial dysfunction, which were evidenced by the decrease of malondialdehyde, p22phox protein expression, number of apoptotic cells, phosphorylated p38 MAPK protein expression, and vascular cell adhesion molecule-1 protein expression while endothelial nitric oxide synthase protein expression was increased. In conclusion, they demonstrated that NO-NIF ameliorated ischemic skin flap necrosis by reducing oxidative stress, apoptosis, and endothelial dysfunction. NO-NIF is considered to be a candidate for the treatment of ischemic flap necrosis.

    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.

    Removing skin lesions from the human body is a simple procedure, but closing the resulting defect may prove a difficult task. The surgeon quite often encounters a problem when the lesion is located in a confined anatomical area where the elasticity of the skin is limited or when the lesion is large. To obviate these difficulties, I present 4 new incisions for closure of circular and semicircular skin defects on difficult parts of the human body such as the scalp, face, axilla, back, and sacrococcygeal areas. This article describes a working model made of white bond paper that can be enlarged or reduced in size using a regular copying machine that can be prepared in advance of surgery to make sure that it adapts to a particular anatomical location. Also, it describes a geometrical analysis in order to determine the distortion of the minimal tension lines of the skin, skin wastage, and length of the suture lines. In summary, it is possible to use a variety of skin incisions, taking advantage of the minimal tension lines of the skin and also taking into consideration the anatomical characteristics of the region involved.

    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.

    2003-01-01

    Full Text Available Tissue adhesive is one of the alternative to conventional suturing and has some added advantages. Fibrin glue has been used in obtaining haemostasis following trauma to spleen and liver. It has also been used in repair of dural tear and bronchial fistula. Fibrin glue is a biological tissue adhesive based on the final stage of coagulation wherein. Thrombin acting on fibrinogen converts it into fibrin. Thus, it has two components, one is fibrinogen and another is thrombin. We have prepared both components of fibrin glue. Fibrinogen was obtained from patient's own blood and thrombin from fresh frozen plasma of screened healthy donor. The glue was used in 20 cases requiring skin graft or flap. The results were compared with conventional suturing method. Use of the fibrin glue is simple, safe, cost effective, and rapid technique to fix the skin grafts and flaps with avoidance of peroperative bleeding and postoperative collection. It also has better overall results.

    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.

    Immediate two-step coverage of dorsal finger and thumb-tip soft-tissue defects with a dorsal flag flap, which can bridge over two fingers if necessary. Soft-tissue defects on the dorsal aspect of fingers between the metacarpophalangeal and the distal interphalangeal joint as well as on the tip of the thumb. Large defects, complex hand trauma, need of a sensible thumb tip, infections, noncompliance. Marking of the flap at the middle phalanx and its flagpole pedicle, containing the dorsal digital artery. The breadth should reach to the middle of the finger and the proximal pole should not cross the middle of the proximal phalanx. With tourniquet dissection of the flap above the peritendineum with respect of the dorsal digital artery and subcutaneous veins in the pedicle. Opening of the tourniquet, in the case of flap perfusion transposition of the flap into the defect. Coverage of the donor site with skin graft. Palmar cast splinting in intrinsic-plus position for 1 week, followed by physiotherapy. Pedicle separation after 3 weeks. Continuation of physiotherapy and scar care. In 2006, ten patients were operated on, three of them for reconstruction of the thumb tip. All patients showed a survival of the flap and a good wound healing without complications. One patient developed a flexion contracture at the donor finger due to noncompliance following immobilization. The functional and aesthetic results were satisfactory in all patients, the average DASH Score ("Disabilities of the Arm, Shoulder and Hand") was 16.4, mainly due to the residuals of the overall injury.

    The most common causes of cheek defects include trauma, burn, and tumor resections. In the reconstruction of the defects in this region, it is essential to use similar or adjacent tissue considering the aesthetic and functional properties. For this purpose, numerous local, regional, or distant free flaps were described. The local flaps harvested from the head and neck region are the most frequent methods because of the similar skin color, texture, and compatibility with cheek.In this study, the reconstruction in a 29-year-old male patient who had a full-thickness cheek defect due to tumor resection on the left side was performed, wherein a hairless skin island was carried through the frontal branch of superficial temporal artery for oral mucosa, and a hairy skin island through the parietal branch of the same pedicle was carried for the bearded skin defect. No complication occurred postoperatively and both aesthetic and functional satisfactory results were obtained, providing the oral mucosal and natural beard integrity. Donor-site scarring and temporal alopecia were recorded as the disadvantages of this method.This technique is a useful method for the reconstruction of full-thickness cheek defects because of its advantages including compatibility of color and texture, reliable blood supply, requiring single-session procedure, and being able to carry 2 different skin islands on the same pedicle.

    The optimal management of severe mastectomy skin flap necrosis continues to remain a challenge. Following autologous reconstruction, small or minor areas of ischemia/tissue necrosis can result in multiple office visits, increased expenses due to dressing supplies and nursing care, and revisional operations. The purpose of this study is to describe outcomes of a common management strategy for surgeons when confronted with a patient with extensive mastectomy skin flap necrosis. Between 1997 and 2010, autologous breast reconstructions were performed in 805 women and 1076 breasts. Of these, 12 patients (15 breasts) were identified who met the criteria for massive skin flap loss (>30%). Patient photographs and wound measurements were used to estimate areas of necrosis. All patients were managed initially with local wound care followed by delayed scar excision. Wound closure was ultimately achieved in all patients. Of the patients, 40% were active smokers in the perioperative period. The average patient age was 49.6 (range, 28-59) years with a body mass index of 30.9. The average mastectomy weight was 959.5 g (range, 223-1520). In-office soft-tissue debridement and local wound care was performed until wound closure was complete, which took place at a mean of 120 days (range, 30-300) after initial surgery. The average patient had a mean of 10 office visits before scar revision. There was an average of 1.7 types of dressing changes needed before wound closure. Topical wound therapy included moisturizing gels, wet-to-dry dressing, and antibiotic ointment. Oral antibiotic therapy was used in 60% of patients. Late scar revision was performed in 87% of the patients at an average of 8.9 months (range, 1-14) after initial surgery. After the initial flap surgery, no patient required skin grafting or hospitalization. Early conservative management followed by late scar revision produced excellent results in patients with massive mastectomy skin flap loss. The outcomes described may

    Insufficient angiogenesis and microcirculatory intravascular clotting have been implicated in the pathophysiology of skin flap failure. Salvianolic acid B (Sal B), isolated from Salvia miltiorrhiza, has been reported to enhance angiogenesis in vitro. This study was aimed to determine the efficacy of Sal B on ischemia-reperfusion injury of the skin flap in Sprague-Dawley rats. Sal B was administered intraperitoneally 2 h before operation, and on the 2nd and 4th days after surgical elevation of an extended epigastric adipocutaneous flap (5 x 7 cm) in ketamine-anesthetized rats. Flap ischemia was achieved by ligating the right superficial epigastric artery and vein and clamping the left superficial epigastric artery and vein for 3 h and then released. Percentage of flap necrosis area (FNA) and plasma levels of aspartate aminotransferase, alanine aminotransferase, creatinine, and malondialdehyde were measured at 7 days after the operation. Animals were divided into six groups, including: vehicle, Sal B low dose (5 mg/kg), Sal B high dose (50 mg/kg) and each with [mesh(+)] or without mesh [mesh(-)] placement. In the three groups with mesh(+), FNA in control flaps was 53.7 +/- 6.9%, whereas low-dose and high-dose Sal B significantly improved flap survival with FNA 27.4 +/- 3.8% and 25.3 +/- 4.3%, respectively (P mesh(-), control flaps were 35.9 +/- 4.5%, whereas high-dose Sal B also significantly improved flap survival with FNA 17.9 +/- 4.7% (P < 0.05, one-way ANOVA). There were no differences in aspartate aminotransferase, alanine aminotransferase, creatinine, or malondialdehyde between groups. We conclude that Sal B attenuates ischemia-reperfusion injury of skin flap, and provides therapeutic potential in reconstructive plastic surgery.

    2014-06-01

    Balistic transfixing hand traumas require a complex reconstruction management. Stabilization and reconstruction of the injuried tissues need a double skin-paddle coverage. We present an original case report of a double skin-paddle scapular/parascapular free flap used to cover a through and through gunshot injury of the right hand. A 14-years-old patient presents a severe and extensive wound with full-thickness palmar and dorsal skin defects, dislocation of the carpal bones, median nerve and flexor tendons losses. Distal vascularization is maintained by the deep palmar arch system supplied by the ulnar artery. The radial artery is severed at the level of the first dorsal interosseous space. The measured defect of the dorsal skin was 12×7cm and the palmar one was 6×3cm. After skeletal stabilization, tendinous and nerve preparation, the hand coverage was performed using a double skin-paddle scapular/parascapular free flap. The vascular anastomoses include an end-to-side arterial suture between the circumflex scapular and the radial arteries, and an end-to-end venous suture between the circumflex scapular and the dorsal radial veins. The scapular/parascapular double skin-paddle free flap is a safe and reliable technique to achieve a dorsal and palmar hand coverage in lack of local flaps alternatives. It can be used as a good option prior to bone graft, tendinous and nervous reconstruction. Copyright © 2013. Published by Elsevier Masson SAS.

    Nisoldipine is a calcium channel blocker with low and variable oral bioavailability. This was attributed to slow dissolution and presystemic metabolism. Accordingly, the objective of this work was to enhance the dissolution rate of nisoldipine to formulate fast disintegrating tablets with rapid dissolution. Binary solid dispersions (SD) were prepared for the drug with hydroxypropyl methyl cellulose E5 (HPMC), polyvinylpyrrolidone (PVP), Pluronic F68 or polyethylene glycol 6000 (PEG 6000). SD formation increased the dissolution rate compared to pure drug with the corresponding physical mixtures failing to provide the same dissolution enhancement. This indicates that the SD enhanced dissolution is not due to the solubilizing effect of the polymer and can be due to physical change in the drug crystal which was confirmed by thermal analysis. SD with HPMC and PVP were selected for preparation of fast disintegrating tablets as they liberated most of the drug in the first 5 min. HPMC-based tablets disintegrated rapidly and released most of the drug in the first 2 min which correlated with the corresponding SD. In contrast, PVP-based tablets disintegrated slowly with gradual dissolution. This can be attributed to the binding effect of PVP. The study developed fast disintegrating tablet for intra-oral administration.

    Based on our previous animal study, we applied the "bridging effect" to the neighboring axial flap through preexpansion and prefabrication of a skin perforator flap as a new method to reconstruct a large skin defect after release of severe neck burn scar contracture. Twelve patients suffering from severe post-burn cervical contractures underwent reconstruction of large skin defects after surgical release of severe scar contractures with preexpanded and prefabricated super-thin skin perforator flaps supplied primarily by a number of perforators via the "bridging effect" from the branches of the adjacent arteries as 2-stage procedures. During the first-stage operation, 2 tissue expanders were placed accordingly, and this was followed by a subsequent second-stage procedure where an expanded super-thin skin perforator flap was transposed to reconstruct a large neck skin defect. Follow-up was between 6 months and 3 years in this series. All super-thin skin perforator flaps survived in this series with primary healing except one with a distal flap necrosis that was treated with a subsequent skin graft. All patients have had a good contour with improved range of motion in the neck. The preexpansion and prefabrication of a super-thin skin perforator flap can possibly improve the anastomoses between neighboring subdermal vascular plexuses and extend the supplying area of these vessels to the flap. This method may provide a favorable super-thin skin flap that can be used for reconstruction of large neck defects after release of post-burn cervical scar contracture as demonstrated in this case series.

  17. Reconstruction of anterior auricular conchal defect after malignancy excision: revolving-door flap versus full-thickness skin graft.

    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.

    Ruptured tendoachilles along with skin defect is a complex problem to reconstruct. Both things require a priority. Single stage reconstruction of ruptured tendoachilles tendon with skin cover using distally based superficial sural arterial flap allows us to perform both. This procedure gives excellent result, shortens the stay, thereby reducing the cost. This method is a simple solution to the complex problem like ruptured tendoachilles with skin defect. In this study, 6 patients with rupture of tendoachilles tendon due to penetrating injury, with skin defect are presented. The repair was done using aponeurotic part of tendoachilles tendon, taken from proximal part of tendoachilles in the midline measuring around 2 to 2.5 cm in width and 8 to 10 cm in length, with intact distal attachment. The tendon was turned upside down by 180 degrees and sutured to the distal stump of the tendoachilles tendon without tension. The skin defect was covered using distally based superficial sural artery flap in the same sitting. The follow-up period was 9 to 30 months. All patients showed good results. In one patient there was distal necrosis of 1.5 cm of the distally based superficial sural artery flap, which healed satisfactorily with conservative treatment. Single stage tendoachilles reconstruction can be used with good functional result and patient satisfaction.

    The dorsalis pedis flap has reliable vascularity; however, its use is limited by reports of donor site morbidity including infection, delayed healing, exposure of tendons, and later contractures. The purpose of this study was to demonstrate its continued role in lower limb trauma when the donor site is reconstructed with MatriDerm to avoid complications. A 65-year-old man presented with a displaced, Gustilo 3b open transverse fracture of his left distal fibula. He had a 2 cm(2) open wound over his lateral malleolus. Following review of possible local options, a dorsalis pedis fasciocutaneous flap was deemed best for coverage, and the donor site was closed with 1-mm MatriDerm dermal matrix and a 6/1000 inch split-thickness skin graft (STSG) in a single stage. Three months postoperatively, the foot had excellent function and cosmesis, with toes in a neutral position and a full range of movement. The dorsalis pedis flap is a valuable reconstructive option for defects of the foot and ankle. Its major limitation donor site morbidity can be overcome by the additional application of a dermal substitute such as MatriDerm under the STSG.

  20. The versatility of a glycerol-preserved skin allograft as an adjunctive treatment to free flap reconstruction

    2009-01-01

    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.

    The purpose of this study was to search for an enhanced blood supply in the distal edge of the skin at the mastoid area in total auricular reconstruction. The authors modified the Nagata method by reserving a subcutaneous fascia pedicle (diameter, 3 to 5 mm) at the intersection of the point 11 to 13 mm from the residual ear tragus (or tragus projection) and 8 to 10 mm from the lowest point of the residual ear lobe. Compared with the traditional Nagata method group, the modified Nagata method group that retained the fascia pedicle of the mastoid skin flap had higher rates of excellent and good flaps (p < 0.05). Auricular reconstruction with the modified Nagata method, retaining the fascia pedicle of the mastoid skin flap, had a reduced incidence of skin flap necrosis.

    To study the treatment results of the pre-expanded flaps for scar contracture on face, neck, and joints by comparing with the skin grafts. A total of 240 cases of scar contracture between July 2004 and June 2014 were included in the study by random sampling; skin grafts were used in 120 cases (skin graft group), and pre-expanded flaps in 120 cases (pre-expanded flap group). There was no significant difference in age, sex, injury sites, and disease duration between 2 groups (P>0.05). Re-operation rate and A&F 0-6 quantization score were used to evaluate the treatment results. The patients were followed up 12 to 75 months (mean, 23.47 months) in the skin graft group, and 12 to 61 months (mean, 19.62 months) in the pre-expanded flap group. The re-operation rate of the skin graft group was 72.5% (87/120), and was significantly higher than that of the pre-expanded flap group (19.2%, 23/120) (P=0.000). The re-operation rate of the neck contracture in teenagers was the highest. It was 93.9% in the skin graft group and 35.0% in the pre-expanded flap group. In the patients who did not undergo re-operations, A&F 0-6 quantization score of the skin graft group was 2.85±1.12, and was significantly lower than that of the pre-expanded flap group (5.22±0.74) (t=13.830, P=0.000). Pre-expanded flap for scar contracture on face, neck, and joints has lower re-operation rate and better aesthetic and functional restoration than skin graft. It should be regarded as the preferred method for teenagers.

    The aim of this study is to examine the enhanced survival effect of ischemic skin flap by combined treatment with bone marrow-derived stem cells (BMSCs) and low-level light irradiation (LLLI). The neovasculogenic effect of BMSCs induced by LLLI was detected using a wound healing and tube formation assay. ICR mice were divided into four groups: control group, LLLI group, BMSCs group, and combine-treated group. The percentage of skin flap necrosis area was calculated on the seventh post-operative day. Specimens were harvested for histologic analyses. LLLI promoted BMSC migration and tube formation. The flap survival rate of combined treated group was significantly higher than that of the control group. Histologic results demonstrated a significant increase in neovascularization in the combined treatment group. This study demonstrates that combination treatment of BMSCs and LLLI could enhance the survival of ischemic skin flap in a mouse model.

    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.

    Background 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. Methods 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. Results 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). Conclusions 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. PMID:26618115

    Full Text Available Random flaps in DM patients have poor reliability for wound coverage, and flap loss remains a complex challenge. The protective effects of aminoguanidine (AG administration on the survival of dorsal random flaps and oxidative stress were studied in diabetic rats. Two months after the onset of DM, dorsal McFarlane flaps were raised. Forty rats were divided into four groups: (1 control, (2 AG, (3 DM, and (4 DM + AG groups. Flap viability, determined with the planimetric method, and free-radical measurements were investigated. In addition, HbA1c and blood glucose levels, body weight measurements, and histopathological examinations were evaluated. The mean flap necrotic areas (% in Groups I to IV were 50.9 ± 13.0, 32.9 ± 12.5, 65.2 ± 11.5, and 43.5 ± 14.7, respectively. The malondialdehyde (MDA and nitric oxide (NO levels were higher in the DM group than in the nondiabetic group, while the reduced glutathione (GSH levels and superoxide dismutase (SOD activity were reduced as a result of flap injury. In the diabetic and nondiabetic groups, AG administration significantly reduced the MDA and NO levels and significantly increased GSH content and SOD enzyme activity. We concluded that AG plays an important role in preventing random pattern flap necrosis.

    The present study aimed to evaluate the effect of one and five sessions of treatment for intra-oral injection phobia in 55 subjects fulfilling the DSM-IV criteria for specific phobia. The subjects were randomly assigned to one or five sessions of cognitive behavioural therapy (CBT) performed by dentists. Assessments included behavioural tests and self-report instruments used pretreatment, post-treatment, and at 1 yr of follow-up. The dental anxiety scale (DAS), the injection phobia scale-anxiety, and the mutilation questionnaires were applied. Mean avoidance duration of intra-oral injections before treatment was 7.0 yr. The results showed that 89% of the subjects had received intra-oral injections from a regular dentist during the 1-yr follow-up. The only significant difference between the one- and the five-session groups was that the five-session group reported less anxiety (as measured using the DAS) at 1 yr of follow-up. It was concluded that both treatments performed by dentists specially trained in CBT have a significant treatment effect on the intra-oral injection phobia.

    Full Text Available Background The aim of this study was to collect important data on the time of oxygensaturation change in relation to skin flap color alteration using non-invasive pulse oximetryto evaluate its ability to provide continuous monitoring of skin flap perfusion.Methods An experimental study on the monitoring of blood perfusion of 20 tube-islandgroin flaps of 10 male New Zealand rabbits was performed using pulse oximetry. The animalswere randomly assigned to one of two groups representing a blockage of either arterial orvenous blood flow. The oxygen saturation change and clinical color alteration were monitoredfrom the beginning of vessel clamping until the saturation became undetectable. The resultwas analyzed by the t-test using SSPS ver. 10.0.Results The mean times from the vessel clamping until the saturation became undetectablewere 20.19±2.13 seconds and 74.91±10.57 seconds for the artery and vein clamping groups,respectively. The mean time of the clinical alteration from the beginning of vein clampingwas 34.5±11.72 minutes, while the alteration in flaps with artery clamping could not bedetected until 2.5 hours after clamping.Conclusions The use of neonate-type reusable flex sensor-pulse oximetry is objective andeffective in early detection of arterial and vein blockage. It provides real-time data on vesselocclusion, which in turn will allow for early salvaging. The detection periods of both arterialocclusion and venous congestion are much earlier than the color alteration one may encounterclinically.

    To determine the indications, frequency of complications and long term outcome associated with axial pattern flaps used to repair wound defects in dogs and cats. Medical records from two independent referral centres for dogs and cats undergoing wound repair with an axial pattern flap were reviewed. Seventy-three animals were included, 49 dogs: 24 cats. Indications for axial pattern flaps were chronic wounds (43/73; 59%) and closure following tumour resection (30/73; 41%). Axial pattern flaps used were: thoracodorsal, caudal superficial epigastric, reverse saphenous conduit, superficial brachial, deep circumflex iliac, superficial cervical, caudal auricular, lateral thoracic, cranial superficial epigastric, genicular and superficial temporal. Postoperative complications occurred in 64 patients (89%) and 8 patients (11%) had no complications. Complications were: dehiscence, swelling of the flap, necrosis, infection, discharge and seroma. Flap outcome was excellent in 16 patients (23%), good in 29 (41%), fair in 21 (30%) and poor in 5 (7%). There is a high complication rate associated with axial pattern flaps but these are usually easily managed and long term outcome is excellent, in either species. © 2015 British Small Animal Veterinary Association.

    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 surgical and chemical delay groups (p = 0.056). In conclusion, this study has shown that polidocanol 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

    Background Local skin flaps often present with flap necrosis caused by critical disruption of the blood supply. Although animal studies demonstrate enhanced angiogenesis in ischemic tissue, no strategy for clinical application of this phenomenon has yet been defined. Hypoxia-inducible factor 1 (HIF-1) plays a pivotal role in ischemic vascular responses, and its expression is induced by the prolyl hydroxylase inhibitor dimethyloxalylglycine (DMOG). We assessed whether preoperative stabilization of HIF-1 by systemic introduction of DMOG improves skin flap survival. Methods and Results Mice with ischemic skin flaps on the dorsum were treated intraperitoneally with DMOG 48 hr prior to surgery. The surviving area with neovascularization of the ischemic flaps was significantly greater in the DMOG-treated mice. Significantly fewer apoptotic cells were present in the ischemic flaps of DMOG-treated mice. Interestingly, marked increases in circulating endothelial progenitor cells (EPCs) and bone marrow proliferative progenitor cells were observed within 48 hr after DMOG treatment. Furthermore, heterozygous HIF-1α-deficient mice exhibited smaller surviving flap areas, fewer circulating EPCs, and larger numbers of apoptotic cells than did wild-type mice, while DMOG pretreatment of the mutant mice completely restored these parameters. Finally, reconstitution of wild-type mice with the heterozygous deficient bone marrow cells significantly decreased skin flap survival. Conclusion We demonstrated that transient activation of the HIF signaling pathway by a single systemic DMOG treatment upregulates not only anti-apoptotic pathways but also enhances neovascularization with concomitant increase in the numbers of bone marrow-derived progenitor cells.

    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.

    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.

  9. Computer-assisted teaching of skin flap surgery: validation of a mobile platform software for medical students.

    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.

    To sum up the efficacy of treatment of pharyngeal fistula through pectoralis major myocutaneous flap combined with fistula local skin inversion in 20 patients. A retrospective analysis of the therapeutic efficacy in 20 cases of laryngeal and laryngopharyngeal cancer with postoperative pharyngeal fistula, to whom double-deck repairing were operated on through pectoralis major myocutaneous island flap combined with inversion of skin around fistula from January 2010 to December 2013. 20 patients were treated by improved pharyngeal fistula inverting suture of pectoralis major myocutaneous flap combined with the skin around the pharyngeal fistula. Flap around the fistula were sutured without tension formation. The pectoralis major myocutaneous flaps were sutured without tension formation covering the inner flanging flap wound. 20 patients were on a nasogastric liquid diet after operation for one week and received antibiotics to prevent infection. Then they all took liquid diet after one week, and had extubation safely later. Stitches were removed 10 more days later. All the twenty patients were recovered successfully, among them, 16 cases recovered in stage Ⅰ and left the hospital 10 days later, 4 cases recovered in stage Ⅱ and left the hospital 20 days later. All the 4 cases recovered in stage Ⅱ were treated with radiotherapy. Fistulas less than 1 cm occurred near their anastomotic stomas at 7 to 14 days after operation. They were healed well by dressing change and pressure dressing. No recurrence was observed during the six months follow-up. Pectoralis major myocutaneous flap combined with fistula local skin inversion is a good way to repair pharyngeal fistula, and it is suitable for the laryngeal and laryngopharynx cancer patients with postoperative throat fistula in an internal diameter larger than 2 cm.

    Between 1983 and 1987, 76 flap grafts were performed in the leg and foot. In general, 3 types of flap were used: --51 ipsilateral flaps, the majority of which were musculo-cutaneous flaps from the medial head of gastrocnemius (17 cases). --17 cross-leg flaps from the opposite limb, the majority of which were medial fascio-cutaneous flaps (13 cases). --8 free flaps, making use of microsurgical techniques. The indications for cross-leg flaps and free flaps have become more limited in favour of local regional pedicle flaps. The lower part of the leg and amputation stumps in the foot are easily covered by distal leg pedicle flaps and amputation stumps of the upper third of the leg can be covered by a flap of fascia lata with a distal pedicle based on the superolateral branches of the peri-articular plexus of the knee.

    Intra-oral magnets are used in dentistry for a variety of purposes, and their susceptibility to corrosion is of great clinical importance. Although a number of in vitro models have been developed to study corrosion of intra-oral magnets, none have attempted to determine the possible contribution to corrosion made by oral bacteria, which are known to form a biofilm on intra-oral appliances. We have exposed demagnetized neodymium/iron/boron (Nd2Fe14B) magnets to an artificial saliva in the presence and absence of a biofilm of Streptococcus sanguils, one of the predominant organisms in the oral cavity. Over a 21-d period, a 3.2% decrease in the mass of the magnets was observed when S. sanguis was present, while in the absence of the organism the decrease in mass was 1.4%. We also examined the ability of poly(para-xylylene), a commonly-used coating, to protect the magnets against corrosion. No decrease in the mass of magnets coated with poly(para-xylylene) was detected over a 21-d period in the presence of S. sanguis. This study has shown that biofilms of S. sanguis cause appreciable corrosion of Nd2Fe14B magnets which is greater than that occurring in the absence of the organism, and that a coating of poly(para-xylylene) provides protection against such corrosion.

    Wine "after-odour" defined as the long lasting aroma perception that remains after wine swallowing is an outstanding characteristic in terms of wine quality but a relatively unstudied phenomenon. Among the different parameters that might affect wine after-odour, the adsorption of odorants by the oral mucosa could be important but has been little explored. In this work, the impact of the chemical characteristics of aroma compounds on intra-oral adsorption was assessed by an in vivo approach that determined the amounts of odorants remaining in expectorated wine samples. In addition, the subsequent aroma release after in-mouth wine exposure was studied by means of intra-oral SPME/GC-MS using three different panellists. Oral adsorption of the aroma compounds added to the wines ranged from 6% to 43%, depending on their physicochemical characteristics. A progressive intra-oral aroma decrease at different decay rates depending on compound type and panellist was also found. The strength of the aroma-oral mucosa interactions seems to explain these results more than the amount of compound adsorbed by the oral mucosa.

    This paper presented our current research about the intra-oral scanner made by MIRDC. Utilizing the sinusoidal pattern for fast phase-shifting technique to deal with 3D digitalization of human dental surface profile, the development of pseudo-phase shifting digital projection can easily achieve one type of full-field scanning instead of the common technique of the laser line scanning. Based on traditional Moiré method, we adopt projecting fringes and retrieve phase reconstruction to forward phase unwrapping. The phase difference between the plane and object can be exactly calculated from the desired fringe images, and the surface profile of object was probably reconstructed by using the phase differences information directly. According to our algorithm of space mapping between projections and capturing orientation exchange of our intra-oral scanning configuration, the system we made certainly can be proved to achieve the required accuracy of +/-10μm to deal with intra-oral scanning on the basis of utilizing active triangulation method. The final purpose aimed to the scanning of object surface profile with its size about 10x10x10mm3.

    Objective: To study the anatomic basis of the bi-pedicled V-Y gastrocnemius myocutaneous flap for repairing the composite Achilles tendon defect. Methods: The pedicle anatomy of the bi-pedicled V-Y gastrocnemius myocutaneous flap was examined on 30 cadaver specimens. The sliding distances of the flap were measured at different knee flexion degrees. The bi-pedicled V-Y gastrocnemius myocutaneous flap was applied in 12 cases of Achilles tendon defect with simultaneous skin and soft tissue defect. Results: The sural arteries could be classified into four types. After cutting off the gastrocnemius origin with a "Z-shaped" incision, the sliding distance of the flap reached (3.7±0.5)cm when the knee flexed 0°,(4.9±0.7)cm when the knee flexed 30°,(6.7±0.7)cm when the knee flexed 60°and (9.2±0.9)cm when the knee flexed 90°. All the defects healed. The patients recovered ambulation with satisfactory knee and ankle function.The follow-up was 4 months -12 years. Conclusions: Different sural artery types should be noticed during the harvest of the bi-pedicled V-Y gastrocnemius myocutaneous flap. With 90°knee flexion,this flap is suitable for one-stage repair of composite Achilles tendon defect within 9.2 cm±0.9 cm.

    Nipple pain is associated with early cessation of breastfeeding and may be caused by high intra-oral vacuum. However identification of high intra-oral vacuum is typically restricted to the research setting. This is the first reported case of an infant with high intra-oral vacuum that was clinically identified through a specific pattern of nipple trauma associated with nipple shield use. Knowledge of clinical signs associated with high intra-oral vacuum may facilitate early recognition of this unusual breastfeeding challenge. The mother of an exclusively breastfed 3 month old infant had severe bilateral nipple pain with minimal trauma that persisted from birth. The nipples were not misshapen immediately after breastfeeding and adjustments to infant attachment at the breast did not attenuate the pain. Examination of the infant's oral anatomy was unremarkable with no ankyloglossia present. Microbiological cultures of nipple swabs and breast milk were negative for bacterial and fungal growth, and prescribed antimicrobial treatments did not reduce the nipple pain. Mild blanching and erythema of the nipples were occasionally observed, and were not consistent with nipple vasospasm. Nipple shields were used regularly as they modified the pain, although this resulted in blisters that corresponded with the nipple shield holes. Measurement of infant intra-oral vacuum during breastfeeding confirmed intra-oral vacuum up to 307 % higher than reference values. Breastfeeding gradually became less painful, and after 6 months was completely comfortable. High intra-oral vacuum is difficult to assess in the clinical setting and is likely an under-reported cause of early weaning that is not well understood. This original case report highlights high intra-oral vacuum as at differential diagnosis to be considered by health professionals when evaluating mothers experiencing strong nipple pain during the initiation of breastfeeding. A clinical screening tool is needed to enable prompt

    Breast-conserving surgery (BCS) has been increasingly performed as a standard operative strategy for patients with breast cancer. The primary purpose of BCS is to acquire both local control and good cosmetic results. An insignificant difference in cancer treatment results has been shown between BCS and total mastectomy. However, achieving sufficiently cosmetic results can be difficult, particularly in patients with tumors that are large or localized to the lower quadrant. To avoid breast deformities and asymmetries after BCS, immediate reconstruction using autologous tissue has been accepted as the standard option. Rhomboid skin and adipose flap repair is a simple, less invasive procedure than the myocutaneous flap, which has primarily been performed in patients with upper quadrant lesions. We herein report the cases of two patients with lower quadrant breast cancer with skin invasion, who underwent BCS with immediate breast repair using a rhomboid flap. This procedure is therefore worth considering as one of the first options for immediate repair after BCS.

Methods: Specific small random pattern skin flaps were designed for repair of facial skin defects in 58 patients after the resection of their lesions. Results: A totle of 7 kinds of 58 pieces of small random pattern skin flaps were designed and applied in repair of facial skin defects. Of all patients, 55 achieved excellent effects with a concealed scar left but without facial deformation. The distal ends of flaps became cyanoderma and superficial blister appeared around it in 3 patients, which healed in the subsequent follow - up. The predilection sites for the formation of skin flaps in decreasing order were bucca, followed by foreheads, nose, eyelids, lips, tempus, eyebrows and mandible regions. The most widely used were sliding advancement skin flaps. Conclusion: Reasonable design of small random pattern skin flaps may result in satisfying thera eutic and cosmetic effects for repair of facial skin defects.

    Full Text Available PURPOSE: To assess the viability of McFarlane skin flaps in rats with administration of sildenafil. METHODS: Twenty Wistar rats were distributed into two groups: Control (dorsal skin flap, subdermal application of saline solution at 0.9% and Study (dorsal skin flap, subdermal application of sildenafil. Seven days after the surgery, flaps were photographed and graphically rendered. Then, they were analyzed with AutoCAD software. Three biopsies (proximal, medial and distal of each flap were collected for histological analysis. RESULTS: Macroscopic analysis showed that animals of the study group had greater necrotic areas (p=0.003 in the dorsal skin flaps. Additionally, histological analysis of the distal third of these flaps showed a tendency to less granulated tissue formation in animals treated with sildenafil. CONCLUSION: Sildenafil subdermally was associated with lower viability of the random skin flap in rats.OBJETIVO: Avaliar a viabilidade de retalhos cutâneos de ratos à McFarlane após a administração de sildenafil. MÉTODOS: Vinte ratos Wistar foram distribuídos em dois grupos: Controle (confecção do retalho cutâneo dorsal, aplicação subdérmica de solução salina a 0,9% e Estudo (confecção do retalho cutâneo dorsal, aplicação subdérmica de sildenafil. Sete dias após a operação, os retalhos foram fotografados e representados graficamente, para serem analisados com o programa AutoCad. Três biópsias (cranial, média e caudal foram coletadas de cada retalho, para análise histológica. RESULTADOS: A análise macroscópica evidenciou que os animais do grupo Estudo apresentaram maiores áreas de necrose (p=0,003 nos retalhos cutâneos dorsais. Além disso, a análise histológica dos terços distais dos retalhos mostrou uma tendência à formação de menos tecido de granulação nos animais que receberam o sildenafil. CONCLUSÃO: O sildenafil subdérmico esteve associado com uma pior viabilidade tecidual dos retalhos cut

    Full Text Available Intra-oral scanners will play a central role in digital dentistry in the near future. In this study the accuracy of three intra-oral scanners was compared.A master model made of stone was fitted with three high precision manufactured PEEK cylinders and scanned with three intra-oral scanners: the CEREC (Sirona, the iTero (Cadent and the Lava COS (3M. In software the digital files were imported and the distance between the centres of the cylinders and the angulation between the cylinders was assessed. These values were compared to the measurements made on a high accuracy 3D scan of the master model.The distance errors were the smallest and most consistent for the Lava COS. The distance errors for the Cerec were the largest and least consistent. All the angulation errors were small.The Lava COS in combination with a high accuracy scanning protocol resulted in the smallest and most consistent errors of all three scanners tested when considering mean distance errors in full arch impressions both in absolute values and in consistency for both measured distances. For the mean angulation errors, the Lava COS had the smallest errors between cylinders 1-2 and the largest errors between cylinders 1-3, although the absolute difference with the smallest mean value (iTero was very small (0,0529°. An expected increase in distance and/or angular errors over the length of the arch due to an accumulation of registration errors of the patched 3D surfaces could be observed in this study design, but the effects were statistically not significant.For making impressions of implant cases for digital workflows, the most accurate scanner with the scanning protocol that will ensure the most accurate digital impression should be used. In our study model that was the Lava COS with the high accuracy scanning protocol.

    Full Text Available Indications for the conservation of the skin flap over the tumor for potential offset of the operational access in aesthetically acceptable zone in patients with primary nodular breast cancer are discussed in the article. The survey results of 203 patients (T1–2N0–3M0 are analyzed. The study revealed that the risk factors affecting the skin flap involvement are the presence of the skin flattening as well as topographic and anatomical characteristics: tumor < 3 cm, located at a depth of < 0.46 ± 0.2 cm, tumor ≥ 3 cm located at a depth of < 1.66 cm. Based on the data the algorithm for immediate breast reconstruction from aesthetically acceptable zone for surgical oncologist is compiled.

    Reconstruction of complex upper extremity defects requires a need for multiple tissue components. The supercharged latissimus dorsi (LD)-groin compound flap is an option that can provide a large skin paddle with simultaneous functional muscle transfer. It is necessary to supercharge the flap with the superficial circumflex iliac pedicle to ensure the viability of its groin extension. In this report, we present a case of a supercharged LD-groin flap in combination with vascularized inguinal lymph nodes, which was used for upper limb reconstruction in a young male patient, following excision of high-grade liposarcoma. Resection resulted in a 28 cm × 15 cm skin defect extending from the upper arm to the proximal forearm, also involving the triceps muscle, a segment of the ulnar nerve and the axillary lymph nodes. Restoration of triceps function was achieved with transfer of the innervated LD muscle. Part of the ulnar nerve was resected and repaired with sural nerve grafts. Post-operatively, the flap survived fully with no partial necrosis, and no complications at both the recipient and donor sites. At 1-year follow up, the patient had a well-healed wound with good elbow extension (against resistance), no tumor recurrence, and no signs of lymphedema. We believe this comprehensive approach may represent a valuable technique, for not only the oncological reconstruction of upper extremity, but also for the prevention of lymphedema. © 2015 Wiley Periodicals, Inc.

    The objective of this work was to propose an automated and direct process to grade tooth wear intra-orally. Eight extracted teeth were etched with acid for different times to produce wear and scanned with an intra-oral optical scanner. Computer vision algorithms were used for alignment and comparison among models. Wear volume was estimated and visual scoring was achieved to determine reliability. Results demonstrated that it is possible to directly detect submillimeter differences in teeth surfaces with an automated method with results similar to those obtained by direct visual inspection. The investigated method proved to be reliable for comparison of measurements over time.

    On 238 intra-oral roentgenograms there were assessed curious process, shape, size extent and depth of defects as well as the possibility of complications in teeth which were not treated. There were assessed 277 defects, out of which 194 in upper teeth and 83 in lower ones. In all the teeth of the maxilla and of the mandible there was found the greatest number of amorphous defects and semilunar contact surfaces. There were also observed a lot of defects in radiciform cementum, thus, often under the gingivae. These are sites difficult for access for clinical examination. That is why radiologic examination is often conclusive in localizing curious process and in accurate diagnosing in the case of pulpits going on. (author). 4 refs, 1 fig., 3 tabs.

    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.

    Background The wound healing process is complex and still poorly understood. Sericin is a silk protein synthesized by silk worms (Bombyx mori). The objective of this study was to evaluate in vivo wound healing effects of a sericin-containing gel formulation in an incision wound model in rats. Material/Methods Twenty-eight Wistar-Albino rats were divided into 4 groups (n=7). No intervention or treatment was applied to the Intact control group. For other groups, a dorsal skin flap (9×3 cm) was drawn and pulled up with sharp dissection. The Sham operated group received no treatment. The Placebo group received placebo gel without sericin applied to the incision area once a day from day 0 to day 9. The Sericin Group 3 received 1% sericin gel applied to the incision area once a day from day 0 to day 9. Hematoxylin and eosin stain was applied for histological analysis and Mallory-Azan staining was applied for histoimmunochemical analysis of antibodies and iNOS (inducible nitric oxide synthase), and desmin was applied to paraffin sections of skin wound specimens. Parameters of oxidative stress were measured in the wound area. Results Epidermal thickness and vascularization were increased, and hair root degeneration, edema, cellular infiltration, collagen discoloration, and necrosis were decreased in Sericin group in comparison to the Placebo group and the Sham operated group. Malonyldialdehyde (MDA) levels were decreased, but superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities were increased in the sericin group. Conclusions We found that sericin had significant positive effects on wound healing and antioxidant activity. Sericin-based formulations can improve healing of incision wounds. PMID:27032876

    The submental island flap is a reliable source of skin of excellent colour, contour and texture match for facial resurfacing and leaves a well hidden donor site. The flap is safe, rapid and simple to raise. We report on its use in 12 cases of facial or intraoral reconstruction. Complications were few. However, there was one case of complete flap loss following its use in a reverse flow manner, due to the presence of an unreported, but constant, valve in the venous system of the face. We believe this flap to be a worthwhile addition to the existing surgical armamentarium.

    Objective To explore the ideal way of using the flaps of Limberg in reconstruction of facial skin defect. Methods 9 cases were diagnosed as skin cancer or nevus of the face on the pathological examination.They were resected and reconstructed using the flaps of Limberg. Results All wounds healed by first intention without venous congestion or infection of the flaps.The color.texture and contour matched well with the face. The incisions were along the margin of the facial aesthetic unit, leaving inconspicuous scars.During 3 to 6 months of follow-up, no tumor or nevus recurred.Doctors and patients are satisfied with the results. Conclusion The flaps of Limberg is a safe and effective procedure for correction of facial skin defect.However, Several principles should be followed when applying the flap. The rotational flap should be designed in the most flexible area and covered an entire aesthetic unit to take the advantage of The Trap Door Deformity. To avoid "Dog ear deformity",subcutaneous pedicle could be employed. If the defect is round, the reading man procedure would be more efficient and preferably.%目的:观察Limberg皮瓣修复面部缺损创面的效果.方法:9例面部肿物切除后皮肤软组织缺损患者设计Limberg皮瓣修复创面.其中肿瘤患者3例;色素痣患者6例.结果:9例患者术后皮瓣均未出现动脉供血和静脉回流障碍,皮瓣色泽、质地较好;伤口Ⅰ期愈合,随访3~6月未见肿物或色素痣复发,瘢痕不明显,形态满意.结论:Limberg皮瓣修复面部中小缺损创面效果良好.设计原则包括:将旋转瓣设计在临近皮肤最松弛区域并且最好完整覆盖一个凸出的美学单位;如果局部旋转后发生猫耳畸形,可以使用皮下蒂皮瓣或者改良的Limberg皮瓣(DuFourmentel皮瓣);如缺损为圆形,用阅读者皮瓣(the reading man procedure)效果可能更好.

    The use of venous flaps is controversial. The mechanism of perfusion of venous flaps is still not fully understood. The research was conducted on 56 white rats. In our experimental work we studied two different models of venous flaps: pedicled venous flap (PVF) and pedicled arterialized venous flap (PAVF). Our results showed that postoperative congestion was present in all flaps. However 66.7% of all pedicled venous flaps and 100% of all pedicled arterialized venous flaps eventually survived. Histological examination revealed that postoperatively the blood flow in the skin of the pedicled arterialized venous flap became «re-reversed» again; there were no differences between mechanism of survival of venous flaps and other flaps. On the 7-14th day in the skin of all flaps were processes of neoangiogenesis and proliferation. Hence the best scenario for the clinical use of venous flaps unfolds when both revascularization and skin coverage are required.

    Full Text Available In the skin, the concept of reperfusion injury is well established. The application of this knowledge to deal with skin flap surgery problems, has a great prophylactic potential. This experimental study was performed to evaluate the action of mannitol as a scavenger of oxygen-free radicals, after an ischemia-reperfusion injury on skin island flaps. Thirty six male Wistar rats were divided into three test groups (n = 12: a non-ischemic group (group I, and two others (groups II and III which were subjected to nine hours of ischemia following by 30 minutes of reperfusion. After seven days, all animals of group II, treated with saline, showed full skin flap necrosis. The assessment of group III, that received a 20% solution of mannitol prior to the onset of reperfusion, revealed 75% (9/12 of flap viability. These results suggest that pre-treatment with mannitol is able to enhance flaps survival with significantly less tissue necrosis (p O conhecimento acerca da lesão decorrente da reperfusão na pele, já encontra-se consolidado.

    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 the world of diagnostic imaging, radiography is an important supplementary method for dental diagnosis. In radiology, special attention must be paid to the radiological protection of patients and health professionals, and also to image quality for correct diagnosis. In Brazil, the national rules governing the operation of medical and dental radiology were specified in 1998 by the National Sanitary Surveillance Agency, complemented in 2005 by the guide 'Medical radiology: security and performance of equipment.' In this study, quality control tests were performed in public clinics with dental X-ray equipment in the State of Sergipe, Brazil, with consideration of the physical parameters that influence radiological protection and also the quality of images taken in intra-oral radiography. The accuracy of the exposure time was considered acceptable for equipment with digital timers. Exposure times and focal-spot size variations can lead to increased entrance dose. Increased dose has also been associated with visual processing of radiographic film, which often requires repeating the radiographic examination.

    The neodymium:yttrium-aluminium-garnet (Nd:YAG) laser is currently used in dental laboratories to weld metals on dental prostheses. Recently, the use of Nd:YAG has been suggested so that dentists themselves can repair broken fixed, removable and orthodontic prostheses by welding metals directly in the mouth. This work aimed to evaluate, through a four k-type thermocouple system on calf jaws, the thermal increase in the biological structures close to the metal parts during laser welding. We put two hemispherical metal plates onto mandibular molars and then laser welded them at three points with a four k-thermocouple system to determine the thermal rise in the pulp chamber, sulcus, root and bone. This procedure was carried out on 12 samples, and the results were processed. The highest values of thermal increase were found in the pulp chamber, 1.5 degrees C; sulcus, 0.7 degrees C; root, 0.3 degrees C; and bone, 0.3 degrees C. This study showed that thermal increases in pulp chamber, sulcus, root and bone were biologically compatible and that intra-oral laser welding, at the parameters used in this work, seems to be harmless to the biological structures close to the welding and thermally affected zones.

    Cinnamaldehyde and nicotine activate the transient receptor potential subtype A1 (TRPA1) channel, which may cause burning sensations. This study investigated whether cinnamaldehyde modulates nicotine-induced psychophysical and physiological responses in oral tissues. Healthy non-smokers (n = 22) received, in a randomized, double-blind, crossover design, three different gums containing 4 mg of nicotine, 20 mg of cinnamaldehyde, or a combination thereof. Assessments of orofacial temperature and blood flow, blood pressure, heart rate, taste experience, and intra-oral pain/irritation area and intensity were performed before, during, and after a 10-min chewing regime. Cinnamaldehyde increased the temperature of the tongue and blood flow of the lip, and was associated with pain/irritation, especially in the mouth. Nicotine increased the temperature of the tongue and blood flow of the cheek, and produced pain/irritation in the mouth and throat. The combination of cinnamaldehyde and nicotine did not overtly change the psychophysical or physiological responses. Interestingly, half of the subjects responded to cinnamaldehyde as an irritant, and these cinnamaldehyde responders reported greater nicotine-induced pain/irritation areas in the throat. Whether sensitivity to cinnamaldehyde can predict the response to nicotine-induced oral irritation remains to be determined. A better understanding of the sensory properties of nicotine in the oral mucosa has important therapeutic implications because pain and irritation represent compliance issues for nicotine replacement products.

    2003-01-01

    A digital intra-oral X-ray imaging sensor with an active area of 3.6x2.9 cm sup 2 and consisting of six charge-integrating CMOS signal readout circuits bump bonded to one high-resistivity silicon pixel detector has been developed and tested. The pixel size is 35 mu m. The X-rays entering the sensor window are converted directly to electrical charge in the depleted detector material yielding minimum lateral signal spread and maximum image sharpness. The signal charge is collected on the gates of the input field effect transistors of the CMOS signal readout circuits. The analog signal readout is performed by multiplexing in the current mode independent of the signal charge collection enabling multiple readout cycles with negligible dead time and thus imaging with wide dynamic range. Since no intermediate conversion material of X-rays to visible light is needed, the sensor structure is very compact. The analog image signals are guided from the sensor output through a thin cable to signal processing, AD conversio...

    The pharmacokinetics of commercial and liposome-encapsulated mepivacaine (MVC) injected intra-orally in healthy volunteers was studied. In this double blind, randomized cross-over study, 15 volunteers received, at four different sessions, 1.8 ml of the following formulations: 2% MVC with 1 : 100 000 epinephrine (MVC(2%EPI) ), 3% MVC (MVC(3%) ), 2% and 3% liposome-encapsulated MVC (MVC(2%LUV) and MVC(3%LUV) ). Blood samples were collected pre dose (0 min) and at 15, 30, 45, 60, 90, 120, 180, 240, 300, 360 min after injections. Liquid chromatography-tandem mass spectrometry was used to quantify plasma MVC concentrations. Pharmacokinetic analysis showed that the maximum plasma concentration (Cmax) and the areas under the curves (AUC(0-360) and AUC(0-∞)) after MVC(2%LUV) and MVC(2%EPI) injections were smaller (P 0.05). Cmax, AUC(0-360) and AUC(0-∞) after injection of the 2% formulations (MVC(2%LUV) and MVC(2%EPI) ) did not exhibit statistically significant differences (P > 0.05). The pharmacokinetics of MVC(2%LUV) were comparable to the pharmacokinetics of MVC(2%EPI). The liposomal formulation of 2% MVC exhibits similar systemic absorption to the local anesthetic with vasoconstrictor. © 2011 The Authors. JPP © 2011 Royal Pharmaceutical Society.

  11. Experiencia en reconstrucción auricular en cáncer de piel con colgajo en "quesadilla" Experience in auricle reconstruction after skin carcinoma with "quesadilla" flap

    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

    Mandibular residual ridge reduction (RRR) after Edlan flap vestibuloplasty, buccal mucosal graft, and split skin graft vestibuloplasty was measured on lateral cephalometric radiographs obtained 1, 3, 6, 12 and 24 months postsurgery in 50 patients. The ridge reduction was most severe during the immediate postoperative period. The different operation methods did not give rise to significant variations in the reduction pattern, neither did the sex of the patient appear to be an important factor. The temporary increase of mandibular resorption after vestibuloplasty surgery is of a magnitude comparable to the average RRR during 1 year in full denture wearers with a long denture experience.

    Ocular disturbances such as blurring of vision, mydriasis, palpebral ptosis, diplopia, ptosis, enophthalmos, miosis, and blindness (temporary or permanent) are rare complications due to intra-oral local anesthesia. Currently, the guidelines to dentists on preventing and caring for such ocular problems are lacking. Hence, we evaluated the knowledge and attitudes of dentists toward ocular complications of intra-oral anesthesia as a means to assess the need for such guidelines. A cross-sectional prospective survey targeting dentists was conducted using a self-administered questionnaire. Totally 500 standardized self-administered questionnaires were sent out by E-mail to practicing dentists or academicians. In total, 390 replies were received, and the data were analyzed. About 39% of graduates and 14% postgraduate dentists knew about ocular complications. Journals were the leading source of information among both graduates and postgraduate dentists. 8.3% graduates and 17.6% postgraduate dentists encountered ocular complications. Interestingly most of the graduates and postgraduates responded that ocular complications are underreported in the literature. 90.5% graduates and 84.3% postgraduates are in the opinion that more research should be carried on ocular complications. 98.3% postgraduates and 97.3% graduates favored the prevention of ocular complications. The dentist's knowledge about ocular complications due to intra-oral anesthesia in our study group is not adequate and needs improvement. Although the awareness and practice of taking preventive measures are satisfactory, there is a need for specific guidelines to dentists in identifying and clinically managing ocular complications of intra-oral anesthesia.

    Full Text Available Abstract Background In the present study, we examined clinical and laser-evoked potentials (LEP features in two groups of chronic tension-type headache (CTTH patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. Methods Eighteen patients with diagnosed CTTH participated in this open label, controlled study. A baseline evaluation was performed for clinical features, Total Tenderness Score (TTS and a topographic analysis of LEPs obtained manually and the pericranial points stimulation in all patients vs. healthy subjects. Thereafter, patients were randomly assigned to a two-month treatment by either amitriptyline or intra-oral appliance. Results and discussion Both the intra-oral appliance and amitriptyline significantly reduced headache frequency. The TTS was significantly reduced in the group treated with the appliance. The amplitude of P2 response elicited by stimulation of pericranial zones showed a reduction after amitriptyline treatment. Both therapies were effective in reducing headache severity, the appliance with a prevalent action on the pericranial muscular tenderness, amitriptyline reducing the activity of the central cortical structures subtending pain elaboration Conclusion The results of this study may suggest that in CTTH both the interventions at the peripheral and central levels improve the outcome of headache.

    To explain the adaptation technique using an intra-oral cone (IOC) for radiation therapy, and to determine the optimal schedule resulting in a high local control rate and an acceptable complication rate using direct electron beam radiation for the treatment of tongue cancer. Thirty patients with the tongue cancer (T1:T2:T3=16:11:3) were treated with 6-15 MeV electron radiation using an IOC. Twenty-six patients were treated with electron radiation using an IOC with or without an excisional biopsy. The other four patients were treated with a combination of the external beam radiation and electron radiation using the IOC. In order to formulate a safe and effective treatment program, we calculated the biologically effective dose (BED). The two- and five-year local control rates for all patients were 63% and 52%, respectively. The two- and five-year overall survival rates for all patients were 73% and 69%, respectively. Local control was achieved in 12 of 15 patients who were irradiated with a BED of 90.9 Gy(10) or more, whereas it was not achieved in nine of the 15 patients who were treated with less than a BED of 90.9 Gy(10) (p=0.03). The application of electron radiation using an IOC for the treatment of tongue cancer provides acceptable local control and adverse effect rates, especially for elderly patients considered to be high risk for complications from anesthesia. The optimum BED(10) value for the treatment of early tongue cancer using the IOC technique appears to be at least 90.9 Gy(10). Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Identification of a dead person is important in starting the investigation into the circumstances of death. In the absence of forensic odontologist, it is vital that general dentists are able to compare the ante mortem-post mortem (AM-PM records and with their ability, correctly interpret the individuality of the person. Aims: This study wascarried out to find out the accuracy with which undergraduate, graduate and post-graduate dentists can do this comparison, using the simulated AM-PM intra-oral peri-apical (IOPA view radiographs. Setting and Design: A total of 60 investigators of which 20 undergraduate students, 20 general dentists, 20 post-graduate dentists viewed 10 pairs of simulated AM and PM radiographs and recorded their findings. Materials and Methods: Ten pairs of simulated AM-PM IOPA view radiographs were given to 60 dentists to investigate their discriminatory potential for dental identification purposes. The results were statistically analyzed. Statistical Analysis: χ2 -test and Mann-Whitney U-test were carried out to compare the sensitivity, specificity and accuracy of the three types of examiners (UG, G, PG. Results: The results showed sensitivity of 59.8%, specificity of 62.6%, accuracy of 61% for undergraduate students, sensitivity of 86.6%, specificity of 87.5%, accuracy of 87% for graduate doctors, sensitivity of 89.3%, specificity of 92.3% and accuracy of 90.5% for post-graduate doctors respectively. Conclusion: Inexperienced investigators in forensic identification showed fairly acceptable results, therefore, introduction of forensic odontology in an undergraduate course may help general dentists to provide better service, if required, in the absence of a forensic odontologist.

    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.

    The rat saphenous flap is described as a new experimental model for free flap studies. This is a fasciocutaneous free flap based on the saphenofemoral vascular pedicle. The flap may include the entire medial aspect of the lower leg between the knee and ankle. Thirty flaps were harvested from 15 inbred rats. Each flap was transferred to the anterior neck of a recipient rat of the same inbred strain so that 15 flaps were vascularized free flaps using the standard end-to-end microvascular technique and the other 15 flaps were nonvascularized free grafts. All but two (technical failure) of the vascularized flaps showed complete survival, whereas all nonvascularized flaps completely necrosed 2 weeks after transfer. It was concluded that the rat saphenous flap has several advantages such as a long and consistent vascular pedicle, ease of harvest, and an all-or-none survival pattern. Furthermore, as a unique feature of this flap, histological analysis revealed that the rat saphenous flap is composed of the skin and underlying fascia without panniculus carnosus. We therefore suggest that the rat saphenous flap is the first true fasciocutaneous free flap model in the rat. In this paper, in addition to illustrating the anatomy of the saphenous vessels and describing a new fasciocutaneous free flap model based on these vessels, we have documented some anatomical details of the rat leg that have never been described in the literature related to the rat anatomy.

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

    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.

    Our aim was to summarize the treatment of degloving injury involving multiple fingers using combined abdominal superficial fascial flap, dorsalis pedis flap, dorsal toe flap, and toe-web flap. Each degloved finger was debrided under microscopic guidance and embedded in the superficial layer of the abdominal fascia. The abdominal skin was sutured to the skin on the back and side of the hand to promote circumferential healing. After removal, the only remaining injured region was on the flexor surface, and this was repaired by multiple dorsal toe flaps, toe-web flaps, and dorsalis pedis flaps to provide blood vessels and sensory nerves. All fingers had proper flap thickness 3-6 months after surgery, and required only lateral Z-plasty modification with web deepening and widening to narrow the fingers and extend their relative length. We completed flap-graft and finger narrowing for 25 fingers in eight patients. Abdominal skin flaps and dorsal toe flaps were grafted, and resulted in both firmness and softness, providing finger flexibility. The dorsal toe flap provided good blood circulation and sensory nerves, and was used to cover the finger-flexor surface to regain sensation and stability when holding objects. During the 1-8 years of follow-up, sensation on the finger-flexor side recovered to the S3-4 level, and patient satisfaction based on the Michigan Hand Outcomes Questionnaire was 4-5. Flap ulcers or bone/tendon necrosis were not observed. Treatment of degloving injury involving multiple fingers with combined abdominal superficial fascial flap, dorsalis pedis flap, dorsal toe flap, and toe-web flap was effective and reliable.

    Full Text Available Recurrent oronasal fistulas after cleft palate repair present a difficult problem for the cleft surgeon. Repeated surgeries to close the fistula results in increased scar formation with associated soft tissue contracture and a resultant increase in fistula size. Although locally available flaps ha s been the standard procedure for closure of small fistulae, Large fistulas requires regional flaps like tongue flaps requiring multistage transfer, with resultant intra oral scarring, to avoid the problems associated with loco regional flaps and recent in crease in success rates of free tissue transfers make them a viable, one - stage means of closing these defects. In this case report we present our clinical experience with recurren t palatal fistula and highlight the effective use of the free vastuslateralis mus cle flap as a means of repair.

    Full Text Available Abstract Background This was a method comparison study. The aim of study was to compare caries information obtained from a full mouth visual examination using the method developed by the British Association for the Study of Community Dentistry (BASCD for epidemiological surveys with caries data obtained from eight, six and four intra-oral digital photographs of index teeth in two groups of children aged 5 years and 10/11 years. Methods Five trained and calibrated examiners visually examined the whole mouth of 240 5-year-olds and 250 10-/11-year-olds using the BASCD method. The children also had intra-oral digital photographs taken of index teeth. The same 5 examiners assessed the intra-oral digital photographs (in groups of 8, 6 and 4 intra-oral photographs for caries using the BASCD criteria; dmft/DMFT were used to compute Weighted Kappa Statistic as a measure of intra-examiner reliability and intra-class correlation coefficients as a measure of inter-examiner reliability for each method. A method comparison analysis was performed to determine the 95% limits of agreement for all five examiners, comparing the visual examination method with the photographic assessment method using 8, 6 and 4 intra-oral photographs. Results The intra-rater reliability for the visual examinations ranged from 0.81 to 0.94 in the 5-year-olds and 0.90 to 0.97 in the 10-/11-year-olds. Those for the photographic assessments in the 5-year-olds were for 8 intra-oral photographs, 0.86 to 0.94, for 6 intra-oral photographs, 0.85 to 0.98 and for 4 intra-oral photographs, 0.80 to 0.96; for the 10-/11-year-olds were for 8 intra-oral photographs 0.84 to 1.00, for 6 intra-oral photographs 0.82 to 1.00 and for 4 intra-oral photographs 0.72 to 0.98. The 95% limits of agreement were −1.997 to 1.967, -2.375 to 2.735 and −2.250 to 2.921 respectively for the 5-year-olds and −2.614 to 2.027, -2.179 to 3.887 and −2.594 to 2.163 respectively for the 10-/11-year

    Oral mucositis is a common and serious side effect in patients who undergo cytotoxic cancer therapies. The purpose of this study was to investigate the preventive effects of rebamipide on radiation-induced glossitis model in rats. Glossitis was induced by a single dose of 15 Gy of X-rays to the snouts of rats (day 0). A novel form of rebamipide liquid comprising its submicronized crystals was administered intra-orally. The preventive effect of rebamipide on tongue injuries was macroscopically evaluated on day 7 following irradiation. The pretreatment period, dosing frequency, and dose dependency of rebamipide were examined. Two percent rebamipide liquid, administered six times a day for 14 days from day -7 to day 6, significantly decreased the ulcer-like area. However, no significant effect was observed when rebamipide was given either from day -4 or from day -1. Four or six times daily, 2% rebamipide liquid significantly inhibited the ulcer-like injury area ratio, but not when given twice daily. Rebamipide liquid, 1, 2, and 4% six times daily significantly reduced the area ratios of total injury and ulcer-like injury in a dose-dependent manner. Gene expression and protein levels of proinflammatory cytokines and chemokines were dramatically elevated in the irradiated tongues of control rats on day 7 without rebamipide liquid treatment. They were dose-dependently and significantly suppressed in rebamipide-treated groups. Intra-oral administration of rebamipide liquid prevented oral mucositis dose-dependently accompanied by the suppression of inflammatory expression in the radiation-induced rats' glossitis model.

    To provide a comprehensive review for development and existing problems of the perforator flaps. The related home and abroad literature concerning perforator flaps was extensively reviewed. The perforator flaps are defined as the axial flaps nourished solely by small cutaneous perforating vessels (perforating arteries and veins), which are exclusively composed of skin and subcutaneous fat. The perforator flaps have the advantages as follows: less injury at donor site, less damage to the contour of the donor site, good reconstruction and appearance of the recipient site flexible design, and short time of postoperative recovery, which have been widely used in reconstructive surgery. The perforator flaps are the new development of the microsurgery, which usher an era of small axial flaps; However, the controversies of the definition, vascular classification, the nomenclature, and the clinical application of the perforator flaps still exist, which are therefore the hot spot for future study.

    The heterodigital arterialized flap is increasingly accepted as a flap of choice for reconstruction of large finger wounds. However, in situations where the adjacent fingers sustained concomitant injuries, the use of this flap as a local flap is precluded. This paper describes our experience with the free digital artery flap as an evolution of the heterodigital arterialized flap. Four patients with large finger wounds were reconstructed with free digital artery flap. Our indications for digital artery free flap were concomitant injuries to adjacent fingers that precluded their use as donor sites. The arterial supply of the flap was from the digital artery and the venous drainage was from the dominant dorsal vein of the finger. The flap was harvested from the ulnar side of the finger. The digital nerve was left in situ to minimize donor morbidity. The donor site was covered with a full-thickness skin graft and secured with bolster dressings. Early intensive mobilization was implemented for all patients. All flaps survived. No venous congestion was noted and primary healing was achieved in all flaps. In addition to providing well-vascularized tissue for coverage of vital structures, the digital artery was also used as a flow-through flap for finger revascularization in one patient. Donor-site morbidity was minimal, with all fingers retaining protective pulp sensation and the distal and proximal interphalangeal joints retaining full ranges of motion. In conclusion, the free digital artery flap is a versatile flap that is ideal for coverage of large-sized finger defects in situations where local flaps are unavailable. Donor-site morbidity can be minimized by preservation of the digital nerve, firmly securing the skin graft with bolster dressings, and early mobilization of the donor finger.

    Objective To discuss the clinical effect of treating skin defect with vasculotrophic flaps around cephalic veins. Methods We used 45 vasculotrophic flaps around cephalic veins to treat 45 patients with skin defect, from February 2008 to March 2012. The follow-up time was 6 months to 1 year, 10 months on average. Based on the surgical methods, the surgical flaps were divided into two classes, one was antegrade flap, with the flap at the distal end of the pedicle. And the other was retrograde flap, with the flap at the proximal of the pedicle. Type I of the second class:reflux vein could be found inside the wound surface, and the cephalic vein inside the flap was anastomosed with the reflux vein inside the wound surface. Type II of the second class: reflux vein could not be found inside the wound surface, and the cephalic vein inside the flap tissues was ligated. Flaps were cut from deep fascial layer, the pedicle width has cephalic vein as the center, not less than 3.0 cm, and the flap length-to-width ratio should not be greater than 5:1. The pedicle of free flap has a strip of skin for reducing tension during suturing. The superficial cutaneous nerves should be kept when cutting the skin flaps. Results Through the method of vasculotrophic flaps around cephalic veins, 45 flaps all survived. As the cutaneous nerve was kept when cutting the flaps, the sensory function of the body was good. Conclusion The cephalic veins exist inside the fascia tissues, and have more concentrated arteries around to supply blood, which provide nutrition to cephalic veins and peripheral tissues. Various vasculotrophic flaps around cephalic veins could be designed by utilizing these tissues for blood supply. As the skin flaps only contain cephalic veins and don't injure nerves and arteries, the damage to the limb is small and higher survival rate, so it has broad application prospects.%目的:探讨头静脉周围血管营养皮瓣修复皮肤缺损的临床疗效。方法对2008年2

    ía vascular clínicamente relacionada de los colgajos perforantes.Over the past 2 decades the use of musculocutaneous perforator flaps has increased worldwide as microsurgeons have become more comfortable with the technique. Perforator flaps have now become well established as a part of the evolution of microsurgery. Since perforator flaps are based on individual musculocutaneous or septocutaneous perforators, it is imperative that the reconstructive microsurgeon has the detailed anatomical information necessary to plan perforator flap transfers. The goal of this paper is to review the various angiographic techniques which are available to study the vascular anatomy of the human body and to present our current vascular injection technique. We will show illustrative examples using the lead oxide gelatin injection technique to elucidate the relevant anatomy of perforator flap donor sites. The lead oxide gelatin injection technique has been previously reported by Salmon and Rees and Taylor. The injection technique may be used for arterial or venous injections but we have primarily used it for arterial injections. The injection steps are detailed in the paper. Over the past five years we have dissected a total of 21 human fresh cadavers after lead oxide gelatin arterial injection studies. A total of over 7000 radiographs have been reviewed and summarized. We present summarized results of the anatomical research in the areas of head and neck, upper limb, torso and lower limb regions. The lead oxide gelatin injection technique is simple and inexpensive and the computer analysis technique is straight forward and provides excellent visualization of the architecture of the human skin. The fine details identified using this injection technique provides useful information to surgeons planning transfers of skin, muscle, bone and nerve and therefore our understandingly of clinically related vascular anatomy of perforator flaps can be improved.

    Objective:To investigate the effects of the tension skin flap with different shapes on the transplantation of the reverse neurocutaneous island flap. Methods:From January 2006 to January 2012,there were 21 patients in the study (in-cluding 15 males and 6 females),and aged from 14 to 58 years old (35 years old on average). Tension skin flaps with different shapes (triangle,round and ellipse) were used to improve the blood supply of the reverse neurocutaneous island flap. The ten-sion skin flaps in the pedicle were designed triangularly (10 patients),spherically (8 patients) or elliptically (3 patients). There were 5 patients with defects in the hand (the size from 5.0 cm×2.0 cm to 8.0 cm×5.0 cm),and 16 patients with defects in the foot and inferior segment of leg,or around the ankle (the size from 6.0 cm×4.0 cm to 13.0 cm×7.0 cm). And all the patients were with the tendon and bone exposed. All the flaps were reversal transplanted ,including 5 dorsal neurocutaneous flaps of foot,4 superficial peroneal neurocutaneous flaps,4 saphenous neurocutaneous flaps,3 sural neurocutaneous flaps,2 superficial radial neurocutaneous flaps,3 lateral neurocutaneous flaps of forearm. And the survival rate,appearance and sensory recovery of the flaps were analyzed. Results:The distant part of the reversed sural neurocutaneous island flap in 1 case necrosized and healed after dressing change. The other flaps survived entirely ,and the donor site all healed primarily. The follow up time was from 3 months to 2 years (averaged 7 months),and all the flaps had recovered pain and warm sensation with perfect appear-ance. Conclusion:The tension skin flap in the pedicle can enhance the blood supply and promote survival rate of the reverse neurocutaneous island flap,and can also improve its appearance.%目的:探讨3种不同形状蒂部减张瓣在皮神经营养皮瓣逆行转移术中的应用及其疗效。方法:自2006年1月至2012年1月,皮瓣坏死患者21例,男15例,女6

    Objective To explore the surgical technique and clinical outcomes of applying the free adipofascial flap nourished by musculocutaneous perforators of the peroneal artery to repair soft tissue defects of the hand. Methods Six cases of skin defects in the hand were treated from December 2007 to October 2009 with free peroneal artery perforator fascial flap. The size of the raised flaps ranged from 5.0 cm × 4.5 cm to 10 cm × 7 cm. In most cases the musculocutaneous branch was chosen as the vascular pedicle for anastomosis.The blood vessels were anastomosed in an end-to-side fashion. The transferred fascial flap was covered with split thickness skin graft, while the donor site was closed directly. Results All the adipofascial flaps survived uneventfully. The skin graft over the fascial flap showed over 90% survival in 4 cases and 80% survival in 2 cases after 7 days. Follow-up time ranged from 3 to 12 months. Flap bulkiness was seen in one case which underwent debulking procedure 3 months later. The appearance of other 5 cases was satisfactory with only slight flap bulkiness. Only a linear scar was left at the calf donor site. Conclusion The free adipofascial flap was a modification of peroneal perforator flaps to minimize morbidity and improve cosmoses of the donor site. The adipofascial flap can also fill the void caused by soft tissue defects and provide better condition for functional reconstruction.%目的 探讨应用游离腓动脉穿支筋膜瓣修复手部软组织缺损,减少供区损伤的方法和临床效果.方法 2007年12月至2009年10月,对6例手部皮肤缺损患者,应用游离腓动脉肌皮穿支筋膜瓣进行修复,切取面积为5.0 cm×4.5 cm~10.0 cm×7.0 cm,以肌皮穿支为蒂.动脉血管蒂与受区血管采用端侧吻合,受区筋膜瓣行断层植皮覆盖.供区创面直接缝合.结果 术后6例筋膜瓣全部存活;术后7 d,筋膜表面植皮成活大于90%4例,80%2例.随访时间为3~12个月,1例皮瓣臃肿,术后3

    The objective of this study was to introduce our preliminary experience on a submerged split-thickness skin graft (STSG) technique combined with secondary vestibuloplasty to rebuild keratinized peri-implant soft tissue and oral vestibule for patients with large oromandibular defects reconstructed by composite flaps. Five patients were enrolled in this study. Stage 1 was submerged STSG and simultaneous implant placement. Stage 2 was the uncovering of the STSG and vestibuloplasty. The implant-borne fixed denture was inserted after this 2-stage treatment. All patients were followed for at least 12 months (average 18 months). Eighteen implants were placed. The rebuilt peri-implant keratinized soft tissue was healthy clinically. The STSG graft had firm adherence to the underlying periosteum. The vestibule had adequate depth to maintain local hygiene. All implants were osseointegrated and all implant-borne prostheses were functioning well. Submerged STSG technique combined with secondary vestibuloplasty may become a feasible and effective solution to rebuild keratinized soft tissue before dental implant restoration.

    It is the aim of the present study to examine the pattern of postoperative changes in the soft tissue profile of 50 edentulous patients after 3 common types of mandibular vestibuloplasty, the Edlan flap operation (n = 15), the buccal mucosal graft (n = 19), and the skin graft vestibuloplasty (n = 16). The soft tissue profile changes were recorded on lateral cephalometric radiographs taken preoperatively, and after 1, 3, 6, 12, and 24 months post surgery. The 3 groups did not differ with respect to clinical features or presurgical cranio-facial morphology. Neither was any significant difference in postoperative profile changes found between the groups. The surgery gave rise, directly and indirectly, to a number of changes in the facial soft tissue profile many of which were interrelated. The chin thickness increased by 2.3 mm, and the lower lip height exhibited a reduction of 1.8 mm at 1 month after surgery as a direct consequence of the operation. After 3 months the profile changes were mostly associated with the reduction of the anterior face height (overclosure).

    We tried to discuss the problems on radiological protection of students in the practice of technique of intra-oral radiography with use of classmates. This radiographic practice has been performed after the technical training use of 'DXTTR' as a preclinical training. The practice was performed as training to take peri-apical, bite-wing, occlusal and eccentric projections. The mean film numbers which were used to complete those technique were 56 films. In these practice, dosimetries were performed on six locations of the body surface of every student who was taken radiograms using thermoluminescent dosimeters (TLD). The measured locations were orbit, bilateral submandible, neck, chest and abdomen. The effective dose equivalent was estimated using weighting factors of International Comission on Radiological Protection (ICRP) pub. 26 and the values of tissue dose equivalent obtained by TLD measurements. The results showed that the mean value of dose equivalent of each part was 5.40 mSv at orbit, 5.06 mSv at submandible, 0.75 mSv at neck, 0.04 mSv at chest and 0.02 mSv at abdomen. The maximum value of effective equivalent dose was 17.03 mSv which was lower than the dose equivalent limit for workers (50 mSv/year) recommended by ICRP pub. 26. The mean value of effective dose equivalent was 2.36 mSv. ICRP recommended the radiation protection for students aged 18 years or over that the procedures for restricting exposure should be broadly similar to those for occupational exposure. So the results indicate that those training was considered to be controlled in some reasonable level. The mean value of risk was estimated to be 3.94 x 10{sup -5}. Because intra-oral radiographic training with use of classmates is performed under extreme non-uniform irradiation, the evaluation of effective dose equivalent was considered to be important to control this special educational exposure and useful for optimization of the educational programs of radiographic technical training

    Reconstruction of complex facial defects using cervical expanded flap prefabricated by temporoparietal fascia flap. Complex facial defects are required to restore not only function but also aesthetic appearance, so it is vital challenge for plastic surgeons. Skin grafts and traditional flap transfer cannot meet the reconstructive requirements of color and texture with recipient. The purpose of this sturdy is to create an expanded prefabricated temporoparietal fascia flap to repair complex facial defects. Two patients suffered severe burns on the face underwent complex facial resurfacing with prefabricated cervical flap. The vasculature of prefabricated flap, including the superficial temporal vessel and surrounding fascia, was used as the vascular carrier. The temporoparietal fascia flap was sutured underneath the cervical subcutaneous tissue, and expansion was begun in postoperative 1 week. After 4 to 6 months of expansion, the expander was removed, facial scars were excised, and cervical prefabricated flap was elevated and transferred to repair the complex facial defects. Two complex facial defects were repaired successfully by prefabricated temporoparietal fascia flap, and prefabricated flaps survived completely. On account of donor site's skin was thinner and expanded too fast, 1 expanded skin flap was rupture during expansion, but necrosis was not occurred after the 2nd operation. Venous congestion was observed in 1 patient, but after dressing, flap necrosis was not happened. Donor site was closed primarily. Postoperative follow-up 6 months, the color, texture of prefabricated flap was well-matched with facial skin. This method of expanded prefabricated flap may provide a reliable solution to the complex facial resurfacing.

    Objective:To evaluate the clinical application and discuss the operative indication of the reverse dorsal metacarpal flap and its compound flap on the skin defects of hand.Methods: From 1990 to 2003, we applied the reverse dorsal metacarpal flap and its compound flap to repair soft tissue defects of fingers in 122 cases, which included 90cases of the reverse metacarpal flap and 32 cases of its compound flaps with tendon grafts, nerve grafts or bone grafts. Based on the follow-up observations, we analyzed the indications of the reverse metacarpal flap and its compound flaps, the postoperative contours, flap colors and textures in comparison to contralateral fingers retrospectively.Results: In the series of 122 cases, flaps survived and the donor site defects were closed directly. The follow-up period ranged from 1-12 years. The postoperative contours,colors and textures of the flaps and its compound flaps were similar to those of normal fingers, although linear scar remained. According to standards of sense recovery(British Medical Research Council, BMRC ), the sense function of the flaps resumed S3 after operation for 1 year.In 10 cases with the tendon defects treated by the flap with tendon grafts, function of flexion-extension of fingers resumed 50%-75% in comparison to the contralateral fingers using the method of measurement of total active motion. In 7 cases with the phalangeal nonunion or bone defects treated by the flap with bone grafts, union occurred after operation for 3 months.Conclusions: To soft tissue defects on fingers with bone or tendon exposure, the reverse metacarpal flap and its compound flap are a better choice for repairing. The range of repairing is up to the distal interphalangeal joint of fingers. The second dorsal metacarpal artery is more consistent and larger as the choice of vascular pedicle, in comparison with other dorsal metacarpal arteries.Postoperative flap color and texture are similar to normal fingers.

    Full Text Available Background The first commercial system for digital radiography was introduced in 1987, and it has evolved a great deal since then. Currently, it is possible to enhance images in digital radiography. Objectives The aim of this study is to evaluate the diagnostic accuracy of image enhancement in direct digital radiography as it relates to interproximal carries assessment. Materials and Methods Following extraction, 50 human teeth were kept in acidic gel (methyl cellulose + acetate buffer PH = 4.8 for 42 days at 37°C to cause caries before mounting. Direct digital radiography was then taken. Two filters were used: sharpen and emboss. Three radiologists evaluated the images with two weeks interval. The histologic assessments were gold standard. Additionally, SPSS 20 was used to draw an ROC curve and calculate AUC. Cohen’s kappa and interclass correlation coefficient (ICC were used to measure intra- and inter-observer reliability. Results For the emboss filter, sensitivity was 95%, specificity was 100%, and accuracy was 96%. For the sharpen filter, sensitivity was 88%, specificity was 100%, and accuracy was 90%. Also, the AUC for the emboss filter was 0.97, and it was 0.94 for the sharpen filter. Cohen’s simple kappa was in the range of excellent. Conclusions Using these filters in intra-oral direct digital radiography (especially the emboss filter can help some clinicians to increase diagnostic accuracy in the assessment of inter proximal caries of posterior teeth.

    Rapid, phasic dopamine (DA) release in the mammalian brain plays a critical role in reward processing, reinforcement learning, and motivational control. Fast scan cyclic voltammetry (FSCV) is an electrochemical technique with high spatial and temporal (sub-second) resolution that has been utilized to examine phasic DA release in several types of preparations. In vitro experiments in single-cells and brain slices and in vivo experiments in anesthetized rodents have been used to identify mechanisms that mediate dopamine release and uptake under normal conditions and in disease models. Over the last 20 years, in vivo FSCV experiments in awake, freely moving rodents have also provided insight of dopaminergic mechanisms in reward processing and reward learning. One major advantage of the awake, freely moving preparation is the ability to examine rapid DA fluctuations that are time-locked to specific behavioral events or to reward or cue presentation. However, one limitation of combined behavior and voltammetry experiments is the difficulty of dissociating DA effects that are specific to primary rewarding or aversive stimuli from co-occurring DA fluctuations that mediate reward-directed or other motor behaviors. Here, we describe a combined method using in vivo FSCV and intra-oral infusion in an awake rat to directly investigate DA responses to oral tastants. In these experiments, oral tastants are infused directly to the palate of the rat--bypassing reward-directed behavior and voluntary drinking behavior--allowing for direct examination of DA responses to tastant stimuli.

    Proper fingertip reconstruction requires good skin and soft tissue coverage, preservation of function and as normal an appearance as possible. The cross finger flap results in negligible joint stiffness, minimal morbidity and little work-time loss. An important factor is the conservation of finger length permitted by this technique. This method of repair is underutilized. It is indicated in several types of fingertip amputations where bone shortening would be detrimental.

    In the present study, we examined clinical and laser-evoked potentials (LEP) features in two groups of chronic tension-type headache (CTTH) patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. Eighteen patients suffering from CTTH (IHS, 2004) participated in the study. We performed a basal evaluation of clinical features and LEPs in all patients (T0) vs. 12 age- and sex-matched controls; successively, patients were randomly assigned to a two-month treatment by amitriptyline or intra-oral device appliance. The later LEPs, especially the P2 component, were significantly increased in amplitude in the CTTH group. Both the intra-oral prosthesis and amitriptyline significantly reduced headache frequency. Total Tenderness Score was significantly reduced in the group treated by the prosthesis. The amplitude of P2 response elicited by stimulation of pericranial zones showed a reduction after amitriptyline treatment. The results of this study may confirm that pericranial tenderness is primarily a phenomenon initiating a self-perpetuating circuit, favoured by central sensitisation at the level of the cortical nociceptive areas devoted to the attentive and emotive compounds of pain. Both the interventions at the peripheral and central levels may interrupt this reverberating circuit, improving the outcome of headache.

    Paramedian forehead flaps are sometimes required to resurface large or deep nasal defects. The flap often needs to be thinned to match the contour of the surrounding skin at the recipient site. We describe a technique to thin the distal potion of the paramedian forehead flap using a flexible razor blade, the Dermablade. Once familiar with it, this same technique may be applied to thin other interpolation flaps.

    The purpose of this study was to determine the corrosive effects of multi-species biofilms on intra-oral magnets in the presence and absence of sucrose. Using pooled human saliva as an inoculum, biofilms were grown on the surfaces of 90 neodymium-iron-boron (Nd2Fe14B) magnets in a constant depth film fermentor under aerobic conditions at 37 degrees C. The fluid phase was a mucin-containing artificial saliva (delivered at a rate of 0.72/litres day-1), and, after 15 days, 100 ml of 10% (w/v) sucrose was added (as three pulses of 33.3 ml) each day for a further 15 days. Six magnets with attached biofilms were removed periodically. On each sampling occasion the numbers of aerobes, anaerobes, streptococci, veillonellae and actinomyces in each biofilm, the pH of the fermentor effluent and the dry mass of the magnets were determined. Addition of sucrose to the fermentor resulted in a fall in pH (from a mean of 6.94 to a mean of 4.96), an increase in the proportion of streptococci and a decrease in the proportion of veillonellae comprising the biofilms. The decrease in mass of the magnets was 28-fold greater in the presence of sucrose than in its absence. The results of this study have shown that the presence of sucrose affects the microbial composition of multi-species biofilms growing on Nd2Fe14B magnets and results in a marked increase in corrosion of the magnets.

MÉTODOS: Foram utilizados 18 ratos adultos jovens, machos (Wistar EPM-1, 290 a 350g, submetidos à elevação de retalho cutâneo de base cranial no dorso, divididos em três grupos (N=6 em função do tempo pós-operatório: imediato (POI, terceiro e sétimo dias (PO3 e PO7, respectivamente. Ao final, foram coletadas amostras de sangue periférico e fragmentos de tecido do retalho e de área cutânea normal fora do retalho para dosagem de MDA e de CAT. RESULTADOS: Para MDA no soro, o grupo POI apresentou valores significativamente menores que os grupos PO3 e PO7, os quais não diferiram entre si. Não foi encontrada diferença entre os valores das amostras cutâneas em nenhum dos três grupos estudados. Para os valores da capacidade antioxidante total (CAT não houve diferença significante entre os três grupos, quando analisado o soro dos animais, no entanto, para as amostras de fragmentos cutâneos, os valores diminuíram significativamente em função do tempo. CONCLUSÃO: A inexistência de diferença para os valores de MDA nas amostras cutâneas entre os grupos e a diminuição dos valores da CAT ao longo do tempo sugere que a presença de necrose na porção distal dos retalhos dos animais do grupo PO7 decorra, não somente da agressão oxidativa, mas também da diminuição da capacidade de defesa antioxidante local.PURPOSE: to study oxidative stress (MDA and total antioxidant status (CAT in fragments of randomic ischemic skin flaps from rat dorsum.

      Objective To explore the effect of autologous skin transplantation with skin flap taken on reverse side using drum type dermatome in treating extensive skin avulsion of upper limbs. Methods Retrospective analysis was con-ducted on 9 patients with extensive skin avulsion of the upper limbs admitted to our hospital from April 2006 to June 2010. All the patients underwent urgent debridement. The avulsed skin soft tissue deprived of blood supply was removed, shaved into medium split thickness skin flaps using drum type dermatome, and replanted them on the wound. Layering dressing was applied with Amikacin Saline gauzes as the inner layer, aseptic bandages in the middle and cotton pads as the outer layer. The injured extremities were suspended post operation to avoid local compression. The outer layer of dressing was changed 3 days post operation and the suture was removed 12 days post operation. Results More than 95% of the transplant survived in the 9 cases. Sporadical small wounds healed with the dressing change of MEBO and no second operation was required. Function of the injured extremities restored sufficiently with exercise. Conclusion Autologous skin transplantation with skin flap taken on reverse side using drum type dermatome is a relatively ideal surgical approach to treating extensive skin a-vulsion of upper limbs. Adequate debridement and hemostasis with appropriate dressing and overhanging to avoid compres-sion can increase the survival rate of the transplant.%  目的探讨上肢大面积皮肤撕脱伤反鼓取皮植皮术的临床效果。方法回顾性分析2006年4月至2010年6月收治的9例上肢大面积皮肤撕脱伤患者病历资料,急诊行清创术,将撕脱失去血供的皮肤软组织取下,用鼓式取皮机修成中厚皮片后,原位回植于创面,术区分层包扎,内层用阿米卡星盐水纱布、消毒绷带包扎,外层用棉垫包扎,术后悬吊,避免局部受压,术后3 d 更换外层敷料,12 d

    Dental radiology is the most frequent radiological diagnosis examination in the industrialised world and it represents almost 25% of all radiological examinations carried out in the European Union. New regulations were established in 1996 which set forth quality criteria in diagnostic radiology to improve medical radiology and to avoid inappropriate exposures. This work contains the first quantitative analysis of the parameters controlled in these compulsory quality control reports, which mean checking the process of obtaining radiological images, as well as development after five years since the establishment of said regulations. Material and Method: 7,176 official quality control reports in diagnostic radiology of dental clinics using intra-oral radiology were studied. The developmental study refers to the first 5 obligatory quality control checks carried out by the UTPR [Technical Unit of Radiology Protection] Asigma S.L. in the second half of 1996 to December 2001, and which mainly concern private facilities. Results: The results show a quantitative analysis of the parameters stated in those reports, with special reference to physical characteristics (kVp, mA, filtration, collimator, length of the exposure switch), as well as operation deviations detected (31% of facilities/year). The characteristics of the process of obtaining radiological images in these facilities was determined (type of developing, control of developing times, replacement of liquids, type of radiographic film, storage and expiry of film) and the average dose of ionising radiation used in the facilities to obtain the radiological image of a same dental part in the usual working conditions of every one of the rooms. All of this in the developmental process during the five years after the establishment of quality control regulations. In short, the results show a decrease of 18.75% in the average doses administered in these fives years of the study. 97.98% of the dental radiological facilities

    Total face skin and soft-tissue defects remain one of the biggest challenges in reconstructive surgery. Reconstruction of the entire face with uniform coverage and delicate features is difficult to achieve. To avoid the patchwork result seen in multiple flaps and skin grafts, 1 monoblock flap that has similar color, texture, and thickness might be an ideal option to minimize the incisional scars and several surgical procedures but is unavailable with current approaches because of the lack of sufficient matched tissue and the unreliable blood supply for such a large flap. To acquire a monoblock flap for full face reconstruction, we combine the prefabricated flaps, skin overexpansion, and bone marrow mononuclear stem cell transplantation for total facial resurfacing. In this article, we present our experience from our case series that provides universally matched skin and near-normal facial contour. It is a reliable and an excellent reconstructive option for massive facial skin defect.

    Halitosis occurs in approximately 30% of the adult population and has a negative social and psychological impact on affected individuals. Mouthwashes may be used to prevent unpleasant odour, with long-duration of effect being a desirable attribute. The aim of this study was to assess the long-term efficacy of CB12 (a mixture of 0.3% zinc acetate and 0.025% chlorhexidine) for the treatment of intra-oral halitosis. Thirty-four subjects with confirmed intra-oral halitosis were randomized into a double-blind, controlled, cross-over study to one of 2 groups; (i) CB12-water-water or (ii) water-CB12-CB12. Each group comprised 3 treatments, each given evening and morning (12 h apart) on consecutive study days, with a 5 d washout between treatments. Intra-oral halitosis was assessed objectively by measuring concentrations of hydrogen sulphide, methyl mercaptan, dimethyl sulphide and total volatile sulphur compound (VSC) concentrations and subjectively using organoleptic score (OLS). These were measured at baseline, 12 h after the evening rinse (i.e. 12 h overnight assessment) and 12 h after the daytime rinse (i.e. 12 h day time assessment). CB12 significantly reduced mean hydrogen sulphide, methyl mercaptan, dimethyl sulphide and VSC concentrations, with a duration of effect lasting 12 h, whether assessed overnight (all p  ⩽  0.0003 versus water) or during the day (all p  ⩽  0.0007 versus water). CB12's effect on OLS was also evident for 12 h overnight (p  =  0.0043). CB12 was well-tolerated. In conclusion, CB12 showed a clear and durable effect on intra-oral halitosis which lasted at least 12 h, both during the day and overnight, with consistent effect on both objective and subjective variables.

    Full Text Available BackgroundSurgical ablation for locally advanced breast cancer results in large chest wall defects, which can then be managed with local flaps or skin grafts. The purpose of this article is to evaluate the outcomes of three types of local skin flaps.MethodsAmong 25 local flaps in 24 patients, 6 were bilateral advancement (BA flaps, 9 were thoracoabdominal (TA flaps, and 10 were thoracoepigastric (TE flaps. Clinical outcomes were compared including complications, the need for a secondary surgical intervention, and the timing of adjuvant therapy.ResultsThe mean defect size was 436.2 cm2. Two patients with TA flaps and 6 patients with TE flaps developed distal flap necrosis, and skin grafts were needed to treat 2 patients with TE flaps. Radiation was administered to the BA, TA, and TE patients after average postoperative durations of 28, 30, or 41 days, respectively. The incidence of flap necrosis tended to be higher in TE patients, which lead to significant delays in adjuvant radiation therapy (P=0.02.ConclusionsThree types of local skin flaps can be used to treat large chest wall defects after the excision of locally advanced breast cancer. Each flap has its own merits and demerits, and selecting flaps should be based on strict indications based on the dimensions and locations of the defects.

    Skin defects of the heel have frequently been reconstructed using the medial plantar flap; however, forefoot coverage has remained a challenge, because the alternatives for flap coverage have been very limited. We describe a case of malignant melanoma on the lateral forefoot that was radically removed and reconstructed successfully with a distally based medial plantar flap, together with a free anterolateral thigh flap. The advantages of this flap include that it does not reduce the vascular supply to the foot owing to reconstruction of the medial plantar vascular systems, reduces the risk of flap congestion, minimizes donor site morbidity, and enables the transport of structurally similar tissues to the plantar forefoot. We believe this technique is a reasonable reconstructive option for large lateral plantar forefoot defects.

    Cryptotia is one of the most common malformations of the upper auricle with aesthetic and functional consequences, however there is no standard treatment. We present the surgical technique and results of a kite flap procedure which can be used in the different cryptotia subtypes. We reviewed all patients treated in our department from 2010 to 2015, using a mastoid fascia kite flap technique. The incision of this local flap follows the retro-auricular sulcus along the rim of the helix superiorly and drawing a skin paddle inferiorly. The mastoid fascia is exposed and a superiorly and posteriorly based flap is drawn and detached from the skull. Finally, the skin paddle is rotated and sutured between the superior helix and temporal skin creating the superior sulcus. The retro-auricular incision is closed directly inferiorly. Six patients (mean age 12) and seven ears were studied. One patient had bilateral cryptotia and only two had a normal contralateral ear. Mean follow-up was of 45 months. There was no skin necrosis, no complications reported and no revision surgery. We describe a reliable flap with a simple design and improved aesthetic result, as the thickness of the flap projects the helix well, the scar is entirely hidden in the retro-auricular sulcus and the direct suture induces a harmonious medialization of the inferior part of the ear and earlobe.

    2009-01-01

    INTRODUCTION: Clinical work on the blood perfusion in skin and muscle flaps has suggested that some degree of blood flow autoregulation exists in such flaps. An autoregulatory mechanism would enable the flap to protect itself from changes in the perfusion pressure. The purpose of the present study...... was to evaluate if, and to what extent, a tissue flap could compensate a reduction in blood flow due to an acute constriction of the feed artery. Further, we wanted to examine the possible role of smooth muscle L-type calcium channels in the autoregulatory mechanism by pharmacological intervention with the L......-type calcium channel blocker nimodipine and the vasodilator papaverine. MATERIAL AND METHODS: Pedicled flaps were raised in pigs. Flow in the pedicle was reduced by constriction of the feed artery (n=34). A transit time flow probe measured the effect on blood flow continuously. Following this, three different...

    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.

    Furthermore, several modifications widen its clinical applications: the fascia lata can be included for sling or tendon reconstruction, the bulkiness could be created by including vastus lateralis muscle or deepithelization of skin flap, the pliability could be increased by suprafascial dissection or primary thinning, the pedicle length could be lengthening by proximally eccentric placement of the perforator, and so forth. Combined with these technical and conceptual advancements, the anterolateral thigh flap has become the workhorse flap for soft-tissue reconstructions from head to toe.

    2003-12-01

    Full Text Available Abstract Background Local flaps are widely used in reconstructive surgery. Tri-lobed skin flap is a relatively new flap and there has been no experimental model of this flap. This flap can be used for repair of full thickness defects in the face, ears and alar region. Based on the size of ears in a rabbit, we designed a model of ear reconstruction using expanded tri-lobed flap. Local flaps are more advantageous in that they provide excellent color and texture matching up with those of the face, adequately restore ear contour, place scars in a favorable location and ideally accomplish these goals in a single stage with minimal donor site morbidity. Methods Eight adult New Zealand rabbits were divided into two groups. 50 ml round tissue expander were implanted to four rabbits. After completion of the expansion, a superiorly based tri-lobed flap was elevated and a new ear was created from the superior dorsal skin of each rabbit. Scintigraphy with Technetium-99m pertecnetate was performed to evaluate flap viability. Results Subtotal flap necrosis was seen in all animals in non-expanded group. New ear in dimensions of the original ear was created in expanded group without complication. Perfusion and viability of the flaps were proved by Technetium-99m pertecnetate scintigraphy. Conclusion According to our knowledge this study is the first to demonstrate animal model in tri-lobed flap. Also, our technique is the first application of the trilobed flap to the possible ear reconstruction. We speculated that this flap may be used mastoid based without hair, in human. Also, tri-lobed flap may be an alternative in reconstruction of cylindrical organs such as penis or finger.

    The buccinator musculo-mucosal island or Zhao flap can be used to reconstruct a wide range of intra-oral defects including floor of mouth, tonsillar fossa and lateral tongue. We describe our experience with the inferiorly based facial artery buccinator musculo-mucosal flap for a novel use in the reconstruction of oropharyngeal tumours at the tongue base and lateral pharyngeal wall. We prospectively reviewed all patients who underwent buccinator musculo-mucosal island flap reconstruction examining indication, operative details, and post-operative outcomes. We describe our technique for its novel use in lateral pharynx/tongue base reconstruction through neck dissection access. Deeper flaps were adequately visualised and monitored using flexible nasoendoscopy. There were no flap failures with all patients achieving primary healing with minimal complications. All donor sites closed directly with minimal scarring. Two patients reported mild tightness on mouth opening and two patients reported transient weakness of the mandibular branch of the facial nerve. In our experience the buccinator musculo-mucosal island flap is an extremely versatile 'like for like' local flap option due to its long arc of rotation. As inset can be achieved via neck dissection access, this avoids lip/jaw split as per conventional oropharyngeal surgical management further minimising morbidity. We present the first series of its effective use in oropharyngeal reconstruction. Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

    Despite the great number of pedicled and free flaps that are available for defect and contour repair, the number of fascia flaps with an axial blood supply are sparse. Such flaps with their gliding function are mandatory, whenever coverage with very thin, well-vascularized tissue is necessary. To the currently established fascia flaps, (the temporoparietal fascia flap, the radial forearm fascia flap, the lateral arm fascia flap, and the serratus anterior fascia flap), we want to add a new fascia flap, the interpectoral fascia flap. We dissected the interpectoral fascia flap from 20 cadavers. In each of the 40 hemichests, the trunk of the thoracoacromial vessels was selectively injected with red polyurethane and the tissue containing the pectoral branches was separated from the overlying pectoralis major muscle and converted into an independent fascia flap. The maximum flap length was 13.5 cm and the maximum breadth was 10.3 cm. The length of the vascular pedicle before entering the flap was 3.9 cm +/- 1.4 cm with a range of 1.5-6.8 cm. Concerning the arc of rotation, all 40 flaps reached the posterior axillary fold, and 29 flaps (73%) reached the mandibular border. This new fascia flap has applications as pedicled and as free flap. The pedicled flap is used in the neck region, in the axillary region and as gliding tissue between the nipple-areola complex and the pectoralis major muscle. The usage of the fascia flap as a free flap has similar characteristics as the other fascia flaps.

    2014-05-01

    The ability to use the anterolateral thigh (ALT) flap as a vascularized fascial flap, without skin or muscle, was first documented by Koshima et al in 1989. The authors mention the possibility of using the fascia alone for dural reconstruction. Despite its description more than 20 years ago, little literature exists on the application of the ALT flap as a vascularized fascial flap. In our experience, the ALT flap can be used as a fascia-only flap for thin, pliable coverage in extremity reconstruction. After approval from the institutional review board, the medical records and photographs of patients who had undergone fascia-only ALT free flaps for extremity reconstruction were reviewed. Photographic images of patients were then matched to patients who had undergone either a muscle-only or a fasciocutaneous free flap reconstruction of an extremity. Photographs of the final reconstruction were then given to medical and nonmedical personnel for analysis, focusing on aesthetics including color and contour. Review of cases performed over a 2-year period demonstrated similar ease of harvest for fascia-only ALT flaps compared to standard fasciocutaneous ALT flaps. Fascia-only flaps were used for thin, pliable coverage in the upper and lower extremities. There was no need for secondary procedures for debulking or aesthetic flap revision. In contrast to muscle flaps, which require muscle atrophy over time to achieve their final appearance, there was a similar flap contour from approximately 1 month postoperatively throughout the duration of follow-up. When a large flap is required, the fascia-only ALT has the advantage of a single-line donor-site scar. Photograph comparison to muscle flaps with skin grafts and fasciocutaneous flaps demonstrated improved color, contour, and overall aesthetic appearance of the fascia-only ALT over muscle and fasciocutaneous flaps. The fascia-only ALT flap provides reliable, thin, and pliable coverage with improved contour and color over

    Large complex odontomas of the jaws are rare. A report of a large complex odontoma of the mandibular angle-ramus region enucleated through intra-oral buccal approach is presented. A review of the literature on different modalities of treatment is also undertaken. A large expansile complex odontoma of the angle-ramus region of the mandible was excised through an intraoral buccal approach under general anaesthesia. Recovery and immediate post-operative period were uneventful. There was no altered sensation in the distribution of the inferior alveolar nerve and lingual nerve; and wound healing was satisfactory. Post-operative radiograph 2 years after the operation showed satisfactory bone regeneration. Intraoral buccal approach to large complex odontomas of the angle-ramus region of the mandible is a relatively safe procedure with minimal complication.

  17. A new flap design for release of parallel contracture bands: dual opposing five-flap z-plasty.

    2014-12-01

    Skin contractures secondary to burn and other types of trauma can be encountered on almost every part of human body, best addressed by a custom treatment protocol tailored for each patient. Skin graft, local flap as well as distant flap options are available, each with intrinsic advantages and disadvantages. In the presence of weblike contracture the utilization of local tissue, when available, is a prefered approach for a relatively better appearance through a reasonably simpler surgical intervention, compared to skin graft applications and distant flap options. Among many other techniques and modalities utilized for this purpose, the dual opposing five-flap z-plasty method which is a novel method designed as a modification of the paired five-flap z-plasty technique promises to be a useful treatment option for the release of parallel contracture bands with satisfactory results in selected patients.

    1985-02-01

    The authors have utilized six pectoralis major myocutaneous flaps in attempts to salvage extensive necrotic wounds of the pharynx and neck. The flap was employed in the following situations: massive necrosis of the entire neck skin with both carotid artery systems exposed, radiation necrosis of the neck skin with exposure of carotid artery, dehiscence of gastric pull-up from pharynx with resultant carotid exposure, failed trapezius flap in a radionecrotic oral cavity, and two cases of pharyngocutaneous fistula with extensive soft tissue necrosis. These flaps achieved healing in all cases. One death occurred 3 weeks following complete cutaneous healing secondary to a ruptured carotid pseudoaneurysm. One flap underwent total skin loss but the entirety of the muscle survived and the fistula was successfully closed with the back of the muscle being subsequently skin grafted. One case of dehiscence of the flap from oral mucosa resulted in a minor exposure of mandible with limited osteoradionecrosis controlled by topical means. This flap has performed extremely well in these precarious and difficult situations that previously may not have been salvageable. It has also been effective in abbreviating the required hospitalization and wound care. The authors conclude that the pectoralis myocutaneous flap should be the primary choice for the management of extensive postsurgical wound necrosis.

    Soft-tissue injuries of the hand frequently require flap coverage to preserve structures damaged at the time of injury or to facilitate later reconstruction. The radial forearm flap makes local tissue readily available and offers a simple method of reconstruction. Secondary augmentation of the skin flap by means of tissue expansion appears to be a useful alternative to improve the possibilities of reconstruction. This case report describes a primary reconstruction of a hand with multiple finger amputations using both techniques: Forearm flap and tissue expansion.

    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. PMID:19881020

    2016-02-01

    Various composite free flaps are available for reconstruction of bony head and neck defects. The aim of this study was to compare the relative success of four different bony free flaps. One hundred and seventy-three microvascular composite free flap reconstructions for bony defects of the head and neck region, performed over the period April 2008 to April 2015, were reviewed retrospectively. The type of free flap, indication for free flap reconstruction, age at harvesting of the free flap, use of pre- or postoperative radiotherapy, and free flap failure were examined. For the 173 reconstructions performed, 84 fibula free flaps, 43 iliac crest free flaps, 32 scapula free flaps, and 14 osteocutaneous radial forearm free flaps were harvested. The mean age at time of harvesting was 40.7 years for the iliac crest, 57.3 years for the fibula, 64.3 years for the scapula, and 73.9 years for the osteocutaneous radial forearm free flap. No complete free flap failure was documented, nor was there any failure of bony segments. Three fibula flap skin paddles did not survive. No returns to theatre for salvage were required.

We present a comparison of the use of the ALT fasciocutaneous (ALT-FC and myocutaneous flaps.MethodsWe retrospectively reviewed patients in whom free-tissue transfer was performed between 2005 and 2011 for the reconstruction of lower extremity soft-tissue defects. Twenty-four patients were divided into two groups: reconstruction using an ALT-FC flap (12 cases and reconstruction using a vastus lateralis myocutaneous (VL-MC flap (12 cases. Postoperative complications, functional results, cosmetic results, and donor-site morbidities were studied.ResultsComplete flap survival was 100% in both groups. A flap complication was noted in one case (marginal dehiscence of the ALT-FC group, and no complications were noted in the VL-MC group. In both groups, one case of partial skin graft loss occurred at the donor site, and debulking surgeries were needed for two cases. There were no significant differences in the mean scores for either functional or cosmetic outcomes in either group.ConclusionsThe VL-MC flap is able to fill occasional dead space and has comparable survival rates to ALT-FC with minimal donor-site morbidity. Additionally, the VL-MC flap is easily elevated without myocutaneous perforator injury.

    Myocutaneous (MC) free flaps are useful for many reconstructive indications. Perforator flaps have become standard of care. The anterolateral thigh flap (ALT) donor site is popular. With the ALT flap varying sizes of vastus lateralis (VL) muscle can be harvested as a MC flap. The skin islands of these flaps have a great range of freedom when dissected on their perforator. It was hypothesised that the VL-ALT perforator flap would offer adequate tissue volume combining maximal freedom in planning with minimal donor site morbidity. From November 2001 to February 2003 a free partial VL with ALT perforator flap was used in 11 patients to reconstruct large defects. Indications for adding a muscular component were exposed bone, skull base, (artificial) dura, or osteosynthesis material, open sinuses, and lack of muscular bulk. Flaps were planned as standard ALT flaps, after which three types of dissection were performed: I. true MC flap; II. muscle flap with a skin island on one perforator, which could be rotated up to 180 degrees ; III. chimera skin perforator flap with muscle being harvested on a separate branch from the source vessel or on a side branch of the skin perforator. Mean skin size of the MC-ALT flaps was 131 cm2. Mean muscle part size of the MC-ALT flaps was 268 cm3. Muscular parts were custom designed for all defects. No total or partial flap failures were seen. Colour mismatch was seen in 6 of 8 patients, when skin was used in the facial area in this all white population. Excessive flap bulk was found in 8 of 11 patients at 6 weeks, however, only in 2 of 11 patients after 6 months. Patients were satisfied with the functional result (8 of 11 patients) as well as the cosmetic result of their reconstruction (7 of 11 patients). All less satisfied patients had received their flap for external facial skin reconstruction. Donor site morbidity was minimal. The combined free partial VL with ALT perforator flap proved valuable as a (chimera type) MC flap with maximal

    Management of long-term bedridden patients experiencing pressure sores still represents a surgical challenge due to limited flap alternatives and high recurrence rates after the treatment. Fasciocutaneous, musculocutaneous, local perforator-based flaps, and free flaps have all been used for treatment of trochanteric pressure sores. This study presents a new use of distal gluteus maximus (GM) muscle as an advancement musculocutaneous flap for coverage of trochanteric pressure sores in 7 patients. The technique involves design of a long V-shaped skin island over the distal fibers of the GM muscle, beginning from the inferoposterior wound edge and extending inferomedially, almost parallel to the gluteal crease. After its harvest as an island flap on the distal fibers of the GM muscle, the skin paddle can be advanced onto the trochanteric defect, whereas the muscle itself is rotated after severing its insertion to femur. If a second triangular skin island is designed on the proximal fibers of GM muscle to cover an associated sacral defect, 2 coexisting pressure sores can be reconstructed concomitantly with 2 skin paddles on a single muscle belly at 1 surgical setting. Of the 7 patients, 3 had 3 (bilateral trochanteric and sacral), 2 had 2 (sacral and trochanteric), and 2 had 1 (only trochanteric) pressure sores. All ulcers were closed successfully and all of the flaps survived totally without any complication except the one in which we experienced minimal wound dehiscence in the early postoperative period. Conclusively, our current surgical method provided a reliable coverage for trochanteric pressure sores although it was technically straightforward and fast. Additionally, it offers simultaneous closure of 2 pressure ulcers with 2 skin islands on a single muscle flap.

    The objective of this study was to assess the ability of a dentifrice containing 8% arginine and calcium carbonate (Pro-Argin' Technology), and 1450 ppm fluoride as sodium monofluorophosphate (MFP) to prevent enamel loss from an erosive acid challenge in comparison to a silica-based dentifrice with 1450 ppm fluoride as MFP using an intra-oral erosion model. The intra-oral clinical study used a double blind, two-treatment, crossover design. A palatal retainer was used to expose the enamel specimens to the oral environment during the five-day treatment period. The retainer was designed to house three partially demineralized bovine enamel samples. The study population was composed of 24 adults, ages 18 to 70 years. The study consisted of two treatment periods, with a washout period lasting seven (+/- three) days preceding each treatment phase. A silica-based dentifrice without fluoride was used during the washout period. The Test Dentifrice used in this study contained 8% arginine and calcium carbonate (Pro-Argin Technology), and 1450 ppm fluoride as sodium monofluorophosphate (MFP). The Control Dentifrice was silica-based and contained 1450 ppm fluoride as MFP. The treatment period lasted five days, during which the panelists wore the retainer 24 hours a day (except during meals and the ex vivo acid challenges) and brushed with their assigned product while wearing the retainer. The panelists brushed once in the morning and once in the evening each day for one minute, followed by a one-minute swish with the slurry and a rinse with 15 ml of water. The panelists brushed only their teeth and not the specimens directly. There were four ex vivo challenges with 1% citric acid dispersed throughout the day: two in the morning, one in the afternoon, and one in the evening. Mineral loss was monitored by a quantitative light fluorescence (QLF) technique. Twenty-three of 24 subjects successfully completed the study. The one subject who did not complete the study did so for

    An intra-oral remineralization study was conducted to compare the ability of a dentifrice containing 8% arginine and calcium carbonate (Pro-Argin Technology), and 1450 ppm fluoride as sodium monofluorophosphate (MFP) to remineralize acid-softened bovine enamel specimens compared to a silica-based dentifrice with 1450 ppm fluoride as MFP. The intra-oral clinical study employed a double blind, two-treatment, crossover design, and used an upper palatal retainer to expose the enamel specimens to the oral environment during product use and periods of remineralization. The retainer was designed to house three partially demineralized bovine enamel samples. The study population was comprised of 30 adults, ages 18 to 70 years. The study consisted of two treatment phases with a washout period lasting seven (+/- three) days preceding each treatment phase. A silica-based dentifrice without fluoride was used during the washout period. The Test Dentifrice used in this study contained 8% arginine, calcium carbonate, and 1450 ppm fluoride as sodium monofluorophosphate (MFP). The Control Dentifrice was silica-based and contained 1450 ppm fluoride as MFP. The treatment period consisted of a three-day lead-in period with the assigned product. The panelists brushed two times per day during the three-day lead-in period with the assigned product. On the fourth day, the panelists began brushing with the assigned product with the retainer in their mouth. The panelists brushed for one minute, followed by a one-minute swish with the slurry and a rinse with 15 ml of water in the morning, in the afternoon, and night with the retainer in the mouth. The panelists brushed only their teeth and not the specimens directly. Changes in mineral content before and after treatment were measured using a Knoop microhardness tester. The results of the study showed that percent remineralization values for the Test Dentifrice and Control Dentifrice were 14.99% and 8.66%, respectively. A statistical analysis

    Microsurgical free tissue transfer is regarded as the best available method of tissue reconstruction for intractable defects. The ideal soft tissue flap is thought to be the anterolateral thigh flap. On the basis of 334 procedures involving the latissimus dorsi (LD) flap, we discuss the advantages of the LD flap over the current universal option, and we aimed to establish whether the LD could also gain universal status in all reconstructive fields.Three hundred thirty-four reconstructive procedures using the LD flap were performed in 322 patients between September 2002 and July 2012. In accordance with defect characteristics, we performed 334 procedures using flaps, which included the LD muscle flap with skin graft, the myocutaneous flap, the muscle-sparing flap, the perforator flap, the chimeric flap, and the 2-flap technique using the serratus anterior branch.Flap-related complications occurred in 21 patients (6.3%), including total and partial flap failure. In 253 cases, the donor site was closed primarily, and in the remaining cases, we used split-thickness skin grafts. Donor-site complications occurred in 20 cases (6%). In 11 of the 182 cases, no suitable perforators were identified during surgery.The advantages of the LD as a donor site include the possibility of various harvesting positions without position change, versatility of components, availability of muscle to fill extensive defects, and presence of thick fascia to enable full abdominal reconstruction. On the basis of our experience, we concluded that this flap has the potential to be used as widely as, or in preference to, the anterolateral thigh flap in most reconstructive areas.

    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.

    Presented at the following academic meetings: ○ 56th Meeting of the Italian Society of Plastic, Reconstructive and Aesthetic Surgery (SICPRE) Fasano (Brindisi), Italy, September 26-29, 2007 ○ 42nd Meeting of the European Society for Surgical Research (ESSR), Warsaw, Poland, May 21-24, 2008 ○ Winter Meeting, British Association of Plastic, Reconstructive and Aesthetic Surgeons, (BAPRAS) London, December 1-3, 2009 Background: The anterolateral free flap has become increasingly popular at our institution year on year. We decided to review our experience with this flap and study the reasons for this trend. Methods: A retrospective review of all anterolateral thigh free flaps performed at Addenbrooke's University Hospital from the available charts was carried out. This chart review included patients' demographics, indications, flap size, recipient vessels used, ischemia time, flap, and donor site outcomes. All flap perforator vessels were located preoperatively using a handheld Doppler ultrasound probe. Results: From October 1999 to December 2008, 55 anterolateral thigh flaps were performed in 55 patients to reconstruct a variety of soft-tissue defects (upper and lower limbs, chest wall, skull base, head and neck). Flap size ranged 12 to 35 cm in length and 4 to 11 cm in width. During flap elevation, the main supply to the flap was found to be a direct septocutaneous perforator in 41% (n = 23) of the cases as opposed to a musculocutaneous perforator, which was found in 59% (n = 32). The mean ischemia time was 82 minutes (range, 62-103). The overall flap success rate was 100%. Two flaps were successfully salvaged after reexploration for venous congestion. The donor site morbidity was minimal. The mean follow-up time was 18 months (range, 2-48). Discussion and Conclusion: The anterolateral thigh free flap was found to be a very reliable flap (100% success) across a wide range of clinical indications. It facilitates microvascular anastomoses as evidenced by the short

    Objective To observe the clinical effect of reverse island skin flaps with sural nerve and blood supplying vessels on repair of tissue defect of lower leg and foot. Methods Fifty-six patients with lower leg and foot tissue defects were hospitalized from June 1997 to August 2007. Among them, 10 patients suffered from soft tissue defect of lower leg; 38 patients suffered from wound infection, exposure of fracture of tibia and fibula, and osteonecrosis; 8 patients suffered from heelstick tissue defect, bone adhering sear, and osteomyelitis. The defects were repaired with sural nerve and blood vessel nourished reverse island skin flaps (46 cases) and myocutaneous flaps(10 cases). The size of flaps ranged from 5 cm×4 cm to 22 cm×16 cm. Flap donor sites were closed by direct suture or free skin grafting. Results Flaps in 55 cases sur-vived. Patients were followed up 3-6 months, there was no complication, and they were healed with satisfac-tory texture and appearance. The patients could walk normally, but with unsatisfactory sensory recovery. In one patient, the flap was broken and ulcerated 1 month after operation on account of leaving behind necrotic tibia. It was healed after second operation.

    The reconstruction of severe defects of the ankle and foot is a challenge. The ideal solution should combine a thin skin flap on the dorsum to allow shoe fitting and a muscle flap with a split-thickness skin graft on the weight-bearing area. Perforator-based thoracodorsal chimaeric flaps allow us to achieve these two goals with minimal donor-site morbidity. We present a reconstruction of an extended circumferential defect of the ankle with an exposed heel using a chimaeric thoracodorsal perforator flap with a serratus muscle flap. The skin flap was transferred on the dorsal foot, whereas the serratus anterior muscle was transferred on the exposed heel. Postoperative recovery was uneventful and the patient began full weight bearing after 3 months. Twelve months after reconstruction, natural shape and walking function were successfully achieved.

    Full Text Available Background: Fingertip defect can be treated with many flaps such as random pattern abdominal flap, retrograde digital artery island flap, V-Y advancement flap, etc. However, swelling in the fingertip, dysfunction of sensation, flexion and extension contracture or injury in the hemi-artery of the finger usually occurs during the recovery phase. Recently, digital artery perforator flaps have been used for fingertip reconstructions. With the development of super microsurgery techniques, free flaps can be more effective for sensory recovery and durability of the fingertip. Materials and Methods: Six cases (six fingers of fingertip defects were treated with free digital artery perforator flaps of appropriate size and shape from the proximal phalanx. During surgery, the superficial veins at the edge of flap were used as reflux vessels and the branches of the intrinsic nerve and dorsal digital nerve toward the flap were used as sensory nerves. The proximal segment of the digital artery (cutaneous branches towards the flap was cut off to form the pedicled free flap. The fingertips were reconstructed with the free flap by anastomosing the cutaneous branches of digital artery in the flap with the distal branch or trunk of the digital artery, the flap nerve with the nerve stump and the veins of the flap with the digital artery accompanying veins or the superficial veins in the recipient site. Results: Six flaps survived with successful skin grafting. Patients were followed up for 6-9 months. The appearance and texture of the flaps was satisfactory. The feeling within the six fingers recovered to S4 level (BMRC scale and the two point discrimination was 3-8 mm. Conclusion: Free digital artery perforator flap is suitable for repairing fingertip defect, with good texture, fine fingertip sensation and without sacrificing the branch of the digital artery or nerve.

    Intra-oral 3D scanning of dentitions has the potential to provide a fast, accurate and non-invasive method of recording dental information. The aim of this study was to assess the reliability of measurements of human dental casts made using a portable intra-oral 3D scanner appropriate for field use. Two examiners each measured 84 tooth and 26 arch features of 50 sets of upper and lower human dental casts using digital hand-held callipers, and secondly using the measuring tool provided with the Zfx IntraScan intraoral 3D scanner applied to the virtual dental casts. The measurements were repeated at least one week later. Reliability and validity were quantified concurrently by calculation of intra-class correlation coefficients (ICC) and standard errors of measurement (SEM). The measurements of the 110 landmark features of human dental casts made using the intra-oral 3D scanner were virtually indistinguishable from measurements of the same features made using conventional hand-held callipers. The difference of means as a percentage of the average of the measurements by each method ranged between 0.030% and 1.134%. The intermethod SEMs ranged between 0.037% and 0.535%, and the inter-method ICCs ranged between 0.904 and 0.999, for both the upper and the lower arches. The inter-rater SEMs were one-half and the intra-method/rater SEMs were one-third of the inter-method values. This study demonstrates that the Zfx IntraScan intra-oral 3D scanner with its virtual on-screen measuring tool is a reliable and valid method for measuring the key features of dental casts.

    Full Text Available Abstract Background Reconstruction of the head and neck after adequate resection of primary tumor and neck dissection is a challenge. It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Cervicopectoral flap is a one such flap from chest and neck skin mainly used to cover the cheek defects. Methods This study included twelve patients presenting with cancer of the head and neck to Izmir Ataturk Training Hospital and Adnan Menderes University Hospital. Tumor resection and neck dissection was performed in one session by the same surgeon. A single incision was made and a medially based cervicopectoral fascio-cutaneous flap was used for surgical exposure in neck dissection and for closure of defects after tumor resection. Results There was no major complication. Two flaps had partial superficial epidermolysis at the suture line. Good aesthetic and functional results were achieved. Conclusion The cervicopectoral 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. This flap achieves perfect surgical exposure, makes neck dissection easy and allows one to perform both tumor resection and neck dissection in one session.

    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.

    Various solutions exist for management of post-pneumonectomy space empyema. We describe the use of a free deep inferior epigastric perforator (DIEP) flap to fill the space and close a pleural window. Previously, flaps involving abdominal muscle or omentum have been used for this purpose. Abdominal surgery to harvest such flaps can impair ventilatory mechanics. The DIEP flap--harvested from the abdomen, and composed primarily of skin and muscle avoids this problem, thus is a desirable technique in patients with impaired lung function. We believe this is the first report of the DIEP flap to close a postpneumonectomy empyema space.

    Galla, T J; Lukas, B; Feller, A M

    1999-03-01

    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.

    Trunk defects following soft tissue sarcoma resection are usually managed by myocutaneous flaps or free flaps. However, harvesting muscle will cause functional morbidities and some trunk regions lack reliable recipient vessels. The intercostal arteries give off multiple perforators, which distribute widely over the trunk and can supply various pedicle flaps. Our purpose is to use various intercostal artery perforator propeller flaps for trunk oncologic reconstruction. Between November 2013 and July 2014, nine intercostal artery perforator propeller flaps were performed in seven patients to reconstruct the defects following sarcoma resection in different regions of the trunk, including the back, lumbar, chest, and abdomen. Two perforators from intercostal arteries were identified for each flap using Doppler ultrasound probe adjacent to the defect. The perforator with visible pulsation was chosen as the pedicle vessel. An elliptical flap was raised and rotated in a propeller fashion to repair the defects. There were one dorsal intercostal artery perforator flap, four dorsolateral intercostal artery perforator flaps, three lateral intercostal artery perforator flaps, and one anterior intercostal artery perforator flap. The mean skin paddle dimension was 9.38 cm in width (range 6-14 cm) and 21.22 cm in length (range 13-28 cm). All intercostal artery perforator flaps survived completely, except for marginal necrosis in one flap harvested close to the previous flap donor site. The intercostal artery perforator propeller flap provides various and valuable options in our reconstructive armamentarium for trunk oncologic reconstruction. To our knowledge, this is the first case series of using intercostal artery perforator propeller flaps for trunk oncologic reconstruction and clinical application of dorsolateral intercostal artery perforator flaps.

    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.

    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.

    Full Text Available The perforator-based flaps in the sacral and ischial region is designed according to the localization of perforators that penetrate the gluteus maximus muscle, reach the intra-fascial and supra-fascial planes with the overlying skin forming a rich vascular plexus. The perforator-based flaps described in this article are highly vascularized, have minimal donor site morbidity, and do not require the sacrifice of the gluteus maximus muscle. In a period between April 2008 and March 2009, six patients with sacral pressure sore were reconstructed with propeller flap method based on superior gluteal and parasacral artery perforators. One flap loss was noted. Three cases of ischial pressure sore were reconstructed with longitudinal propeller flap cover, based on inferior gluteal artery perforator. One flap suffered wound infection and dehiscence. Two cases of pilonidal sinus were reconstructed with propeller flap based on parasacral perforators. Both the flaps survived without any complications. Donor sites were closed primarily. In the light of this, they can be considered among the first surgical choices to re-surface soft tissue defects of the sacral and ischial regions. In the series of 11 patients, two patients (18% suffered complications.

    Objective To explore the clinical outcome of free super⁃thin anterolateral femoral perforator lobulated skin flap with nerve for repairing the tissue defect of the foot and ankle. Methods Free super⁃thin anterolateral femoral perforator lob⁃ulated skin flap with nerve was transferred to repair soft tissue defects of the foot and ankle in 32 cases. There were 20 males and 12 females with an average age of 35.5 years (range, 21-50 years). The wounds located in dorsal and plantar ankle skin with ten⁃don, bone and/or internal fixation exposed. The defect area was from 12 cm×10 cm to 20 cm×15 cm. At first the site of perforator vessels were determined by Doppler, according to the wound shape and size, the flaps were designed and harvested with the site as center;the femoral lateral cutaneous nerve was carried and most tensor fascia was reserved. During flap harvesting trimming of the flap was carried out, the flap was freed and only connected with its vascular pedicle. A step⁃wise defatting was done from the pe⁃riphery of the flap towards the vascular pedicle with 1.0 to 2.0 cm tissue around the perforator preserved. Flap circulation was care⁃fully observed to prevent damage to the perforators. The vascular pedicle was disconnected and formed a split leaf skin flap, and then the flap was transferred to the foot and ankle to cover the defect. Results All the 32 flaps were survived. No vascular crisis happened and all skin grafts were survived in donor sites. Necrosis of 1.5 cm×1.0 cm of the distal flap occurred in 1 case five days after surgery and it was healed by dress changing. All the 32 cases were followed⁃up for 6 to 24 months (average, 13 months). The flaps were supple and elastic with near normal color. There was no bulkiness. Sensory function was recovered well and two point discrimination (2⁃PD) was about 3.0-5.0 mm. The function and appearance of the foot and ankle were good. According to the Chi⁃nese Medical Association of hand surgery

    Full Text Available Objective: to determine the capabilities and perspectives of island and perforator flaps for soft tissue reconstruction of the hand. Material and methods. Results of treatment of 41 patients with defects of the soft tissue of the hand, treated at the in the period from 2010 to 2013 and operated using the island flaps and perforator flaps (DAP flap. Results and conclusion. In all cases the authors have received positive functional and cosmetic results, which were evaluated using a questionnaire DASH, the average score was 12.3. Digital artery perforator flaps allow close defect covering tissue any surface fingers. The use of perforator flaps allows reconstructing soft tissue defect with the skin of the same anatomical region as identical morphologically lost. The second important advantage is that the DAP flap is not included in the magisterial arteries, allows its use as a recipient for subsequent microsurgical reconstructions.

  19. Effects of vascular endothelial growth factor on survival of surgical flaps: a review of experimental studies.

    2014-01-01

    Partial or complete necrosis of skin flaps remains a significant problem in plastic and reconstructive surgery. Growth factors have shown promise in improving flap survival through increased angiogenesis and blood supply to the flap. Vascular endothelial growth factor (VEGF) is the most widely investigated and successful one. But the mechanisms of the effects are still not very clear. In the course of a series of experiments, we indicated that tissue survival of surgical flaps could be improved by both preoperative (sustained phase effect) and intraoperative (acute phase effect) application of VEGF. We reviewed both experimental and clinical investigations on the use of VEGF with surgical flaps to summarize the evidence of both phases of VEGF activity in promotion of flaps survival in detail. With the combinations of acute and sustained phases of effects, VEGF protein and gene, VEGF morphologic actions, and VEGF histochemical modulations suggest a pattern of VEGF activity that can be superimposed on classic descriptive mechanisms of tissue survival of flaps.

    2011-04-01

    Full Text Available The distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. However, perfusion problems and venous congestion have been reported. Over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. The purpose of this paper is to describe our experience in harvesting the reversed large sural flap from the proximal and middle third of the leg for large defects on the foot. We applied the extended reversed sural flap from the proximal third of the leg in traumatized patients which had large defects on their foot. The technique was done in 3 parts: 1- the flaps were designed in the proximal third of the leg five centimeter lipofascial tissue was protected around the pedicle in distal part; 3- The pivot point was located in seven to eight cm proximal the lateral malleolus before the first fasciocutaneous perforators arising from the peroneal artery. Sural flaps from the proximal and middle third of the leg were designed in13 patients who had large defects on their foot. No flap necrosis or split thickness skin graft loss occurred. The flaps healed by the 3rd week excluding two patients. This study supports the application of our technique as a safe, easy and useable method in large defects of the foot. The results showed low rates of ischemia, venous congestion, dehiscence, infection and flap necrosis. Proximal extended and large distally based sural flap is an alternative to free tissue transfer for large defect reconstruction of the foot.

    Tensor fascia lata pedicled flap is one of the most useful flaps for reconstruction pressure sore defects on trochanteric region. Debate exists on the safe dimension of the flap, as distal tip necrosis can be encountered. The aim of the current study is to report experience of Clinic for Plastic and Reconstructive Surgery, Clinical University Center of Sarajevo, with tensor fascia lata pedicled flap in reconstructing trochanteric pressure sore defects. From January 1993 to December 2007, 39 pedicled TFL flaps were used for reconstruction trochanteric pressure sore defects in 34 patients. We used 3 local flaps for reconstruction of small trochanteric defects and one direct suture. In our study we had 43 trochanteric pressure sores and in 9 patients pressure sores were bilateral. The age ranged from 9 to 65, with average age 41,2. The resulting trochanteric defects in this study were due to debridement of pressure sore. The size of the flaps used ranged from 15 x 6 cm to 30 x 15 cm. All flaps survived. Distal tip necrosis occurred in 4 cases. All 4 cases developed in a very large flap beyond the safe limits. Wound dehiscence occurs in 3 cases. There was minimal donor side morbidity in the form of partial skin loss in 1 case. The average follow up period in this study ranged from 6 months to 15 years. Tensor fascia lata flap is reliable flap. Donor site morbidity is minimal. Problem with the flap can be encountered if the flap is not harvested with the safe limits and properly designed. Proper preoperative preparations must be taken into consideration. Chronic skin ulcers, such as pressure sores, that are refractory to conventional local wound therapies, are good examples of potential beneficiaries of the TFL musculocutaneous flap.

    The composite tissue flap of the descending genicular vessels with the adductor magnus tendon is a newly developed, reliable method to repair the Achilles tendon and relevant skin defects. The aim of this study was to evaluate the anatomy of the adductor magnus tendon-descending genicular artery bone flap, and the feasibility and value for the repair of the Achilles tendon and relevant skin defects. There were 34 adult specimens used for the anatomy of this flap. The descending genicular artery originates 10.5 ± 1.6 cm above the adductor tubercle, with a diameter of 1.8 ± 0.6 mm and a length of 1.2 ± 0.5 cm. Its articular branch is distributed in the adductor magnus tendon and the medial condyle of the femur. The saphenous branch has a diameter of 1.1 ± 0.3 mm and is distributed in the skin of the upper medial calf. A total of 16 cases of trauma-induced Achilles tendon damage and calcaneus and skin defects were repaired with the vascularized adductor magnus tendon bone flap, including the reconstruction of Achilles tendon insertion and repair of relevant skin defects. All of the composite tissue flaps were viable, the skin sensation of the flaps was recovered, and all patients walked with a normal gait. Our results suggested that the adductor magnus tendon-descending genicular artery bone flap is an alternative method to repair composite tissue defects of the Achilles tendon.

    Full Text Available To date, many techniques have been reported for vaginoplasty in male-to-female trans-sexual (MTFTS patients, such as the use of a rectum transfer, a penile-scrotal flap and a reversed penile flap. However, none of these procedures is without its disadvantages. We developed a newly kind of flap for vaginoplasty, the M-shaped perineo-scrotal flap (M-shaped flap, using skin from both sides of the scrotum, shorn of hair by preoperative laser treatment. We applied this new type of flap in 7 MTFTS patients between January 2006 and January 2007. None of the flaps developed necrosis, and the patients could engage in sexual activity within 3 months of the operation. The M-shaped flap has numerous advantages: it can be elevated safely while retaining good vascularity, it provides for the construction of a sufficient deep vagina without a skin graft, the size of the flap is not influenced entirely by the length of the penis, and it utilizes skin from both sides of the scrotal area, which is usually excised.

  6. AN ANATOMIC STUDY OF ADIPOFASCIAL FLAP OF THE LEG

    Objective To investigate the vascular anatomy of the subcutaneous tissues and fascias of the leg. Methods Four fresh cadaver legs which had been injected with colored latex were dissected under magnification to identify the origin, course an distribution of vessels from the subfascial level to the skin. The adipofascial flap was harvested from the whole medial side of the leg and fascial flap from other leg of the same cadaver. The posterior tibial artery and its first and second supra-malleolus septal arteries were retained in these flaps. Selective injection of China ink through posterior tibial artery was carried out, and dimension of ink- stained areas was recorded. Results Three main trunk vessels of the leg gave off branches to deep fascia and subcutaneous tissues, forming a large vascular plexus in the subcutaneous tissues on the deep fascia and a deli- cate, but dense and well anastomosed vascular plexus beneath the deep fascia. The vascular plexus in the subcu- taneous tissues ran deeper than the superficial venous system. The areas stained by selective injection in adipo- fascial flaps were larger than those in the fascial flaps. Conclusion Subcutaneous tissues and deep fascia can be considered as an anatomic entity nourished by two very well developed vascular networks which lie on both sides of deep fascia. Incorporation of the deep fascia can not only protect the subcutaneous tissue from being lacerated during raising of the flap, but also enhance vascularity of the adipofascial flap. Leaving superficial veins intact while raising the skin flap does not jeopardize the vascular plexus in the subcutaneous tissues and can preserve the superficial lymnphatic vessels, so that postoperative edema of the flap or the leg could be avoided.

    Full Text Available Background: Post-burn axillary and elbow scar contracture is a challenging problem to the reconstructive surgeon owing to the wide range of abduction and extension that should be achieved, respectively, while treating either of the joint. The aim of this paper is to highlight the use of subcutaneous pedicle propeller flap for the management of post-burn axillary and elbow contractures. Methodology: This is a prospective case study of axillary and elbow contractures managed at a tertiary care hospital using propeller flap based on subcutaneous pedicle from 2009 to 2014. Surgical treatment comprised of subcutaneous-based pedicle propeller flap from the normal tissue within the contracture based on central axis pedicle. The flap was rotated axially to break the contracture. The technique further encompassed a modification, a Zig-Zag incision of the flap, which was seen to prevent hypertrophy along the incision line. There was a mean period of 12 months of follow-up. Results: Thirty-eight patients consisting of 22 males and 16 females were included in this study among which 23 patients had Type II axillary contractures and 15 had moderate flexion contractures at elbow joint. The post-operative abduction achieved at shoulder joint had a mean of 168° whereas extension achieved at elbow had a mean of 175°. The functional and aesthetic results were satisfactory. Conclusion: The choice of surgical procedure for reconstruction of post-burn upper extremity contractures should be made according to the pattern of scar contracture and the state of surrounding skin. The choice of subcutaneous pedicle propeller flap should be emphasised because of the superior functional results of flap as well as ease to learn it. Moreover, the modification of propeller flap described achieves better results in terms of scar healing. There is an inter-positioning of healthy skin in between the graft, so it prevents scar band formation all around the flap.

    Although the radial forearm free flap has become a workhorse flap in head and neck reconstruction, the skin grafting of the donor is the main drawback resulting in an unacceptable contour deformity and an unsightly appearance. Several technical modifications have been therefore applied to the radial forearm (RF) flap marking, elevation, and inset to overcome this major shortcoming. In this article, we report our clinical series with the bipaddle RF flap. The authors described their 11 cases of head and neck oncologic reconstruction with the bipaddle RF flap. The skin island is designed longer and narrower and split into 2 separate skin paddles each nourished by a proximal and a distal independent perforators raising from the radial artery so that the donor site could be closed directly. The narrow design of the skin paddle and the subsequent splitting in its 2 components applying the "perforator-pedicle propeller flap method" allow for the changing of the flap shape according to the shape of the recipient site defect. From 2007 to 2013, the bipaddle RF flap method was used in 11 patients to restore head and neck defects following cancer ablation. The mean age of the patients was 43 years, ranging from 31 to 50 years. The location of the defects was the tongue (n = 7) and the intraoral region (n = 4). The defect sizes varied from 4 × 5 cm to 5 × 6 cm, and the flap maximum width was 3 cm with mean area of 26.4 cm. The healing was uneventful in all patients with excellent cosmetic and functional results of both donor site and recipient site after 20 months of mean follow-up. The bipaddle RF free flap is a reliable and versatile option for the reconstruction of a wide range of soft tissue defects of head and neck region. This method allows for a customized resurfacing of the defect because of its large variability in shape and size. The harvesting site is closed primarily, and a second donor site for skin graft is avoided.Clinical Question, Level of Evidence

    Conclusion: Treatment modalities include early wide local excision to clear margins, ensuring further local recurrence and distant metastasis. The use of local V-Y advancement fasciocutaneous flaps may be another valid option for the reconstruction of perianal skin defects, with less morbidity than other flaps described in the literature.

    The authors propose a combined flap technique to reconstruct large and medium-sized ptotic breasts in a single-stage operation by use of anatomical permanent implants. The authors enrolled 28 patients fulfilling criteria for skin-sparing mastectomy and presenting with ptotic breasts whose areola-to-inframammary fold distance was more than 8 cm. All reconstructions were performed as a single-stage procedure. After preoperative planning, a large area in the lower half of the breast was deepithelialized according to the conventional Wise pattern. Mastectomy was then carried out. To perform reconstructions, the inferomedial fibers of the pectoralis major muscle were dissected and sutured to the superior border of the inferior dermal flap. An anatomical implant was then inserted into the pouch, which was closed laterally with the previously harvested serratus anterior fascia. Skin flaps were finally closed down to the inframammary fold. The authors performed 30 procedures on 28 patients. The medium size anatomical implants was 433 cc. Twelve women achieved symmetrization in a single stage ending in a symmetric inverted-T scar. The overall complication rate was 20 percent, with four cases (13 percent) complicated by severe, extensive necrosis of the skin flaps requiring implant removal. Breast cancer treatment must nowadays optimize cosmetic results. This can be accomplished in selected cases by means of a single-stage operation that the authors call "skin-reducing mastectomy." The final scars imitate those of cosmetic surgery. Careful patient selection and improvement in the learning curve may reduce the complication rate.

    We present a 10-year retrospective study at a tertiary center designed to evaluate the advantages, complications, and comparative results using lateral circumflex femoral artery (LCFA) system free flaps for cranial base reconstruction. In this study, a cranial base defect refers to exposed intracranial contents to the skin, paranasal sinuses, nasopharynx, oropharynx, or oral cavity. These defects resulted from resections of primary or recurrent neoplasms or from secondary problems after cranial base surgery. We performed 20 flaps in 20 patients. The selection of flap was as follows: 8 combinations of anterolateral/anteromedial thigh flaps with vastus lateralis muscle or tensor fascia lata flaps, 6 ALT fasciocutaneous flaps, and 6 muscle/myocutaneous flaps. The flap's success rate was 95% (19/20). Early major complications included 1 perioperative death, and there was 1 myocardial infarction. Minor complications included 1 partial (12%) flap loss, 2 temporal cerebrospinal fluid leak, 2 donor-site hematoma, 2 minor wound breakdown, 3 facial nerve weakness, and 4 donor-site numbness. Among 20 patients undergoing LCFA system flap reconstruction, 12 are alive and disease free. Local recurrence occurred in 1 patient. She underwent ablative surgery and a new successful free flap (forearm flap); after 2 years, the patient is disease free. The LCFA system flaps in skull base reconstruction provide versatility in flap design and availability of adequate tissues to fill dead space, and it offers vascularized fascia to augment dural repairs. It also provides a very long pedicle and allows simultaneous flap harvest with low donor-site morbidity.

    Background In the past decade, there has been increasing breast reconstructions after mastectomy. The ideal material for reconstruction of a breast is fat and skin. The transverse rectus abdominis myocutaneous (TRAM) flap has been the gold standard for breast reconstruction until recently. Abdominal wall function is a major concern for plastic surgeons in breast reconstruction with TRAM flaps. The deep inferior epigastric perforator (DIEP) free flap spares the whole rectus abdominis muscle, includes skin and fat only, and therefore preserves adequate abdominal wall competence. The aim of this study was to summarize our experience in breast reconstruction with DIEP flap.Methods Between March 2000 and August 2005, a total of 43 breast reconstructions were performed on 40 patients by our surgeons using DIEP flap (3 patients had bilateral procedures), 14 of them were immediate surgeries and 26 were delayed. Abdominal function, satisfaction with the donor site and reconstructed breast, and the sensation recovery was assessed respectively during follow-up.Results The mean age of the patients was 38.6 years (range, 28-50). The size of the flaps was 11 cm×26 cm in average (height 10-12 cm, width 15-33 cm). The mean length of the vascular pedicles was 9.3 cm (range, 7-12). The patients were followed up for a mean of 16 months (range, 6-30 months). During the follow-up, 2 (5%) patients had total flap loss, 2 (5%) had partial necrosis, 4 (9%) had wound edge necrosis in the abdomen, and 1 had axillary seroma. None of the patients had hernia, and all of them were able to resume their daily activities after the operation. Patient satisfaction with the reconstructed breast rated high, 95% of the patients achieved spontaneous return of sensation in the reconstructed breast, but none of them had a sensation equivalent or approximate to the normal.Conclusions The DIEP flap has the same benefits as the TRAM flap without destroying the continuity of the rectus muscle. It can reduce

    The anatomical and function characteristics of the heel region explain the large number of methods used and the differences of opinion particularly in relation to the repair of weightbearing zones. Our study is based on 28 patients in whom we performed: ten regional flaps, six cross-leg flaps, sixteen microsurgical flaps. The temporal fascia free flap provides good results on the posterior surface with minimal sequelae at the donor site. The medial plantar flap appears to be the most suitable flap for weight-bearing zones. Cross-lep flaps allow satisfactory repair of the weightbearing zone, but the scarred appearance of the donor site is inaesthetic and immobilisation is uncomfortable. The problem of large defects is still not resolved and no really satisfactory method is available among the various distant, skin, myocutaneous, pure muscle or cross-leg flaps. The solution may reside in a combination of two flaps allowing better adaptation to the morphology of the heel. The importance of heel sensation, particularly in the weight-bearing zone, led to the concept of the use of sensitive or resensitised flaps. After a review of the literature and our results, we did not find any correlation between the sensitivity obtained and the success of the reconstruction. It therefore seems useless to perform microscopic nerve sutures in order to resensitise distant heel flaps. The patient's cooperation is essential in every case to compensate for the decreased sensitivity by means of increased visual surveillance and the wearing of suitable shoes.

    It is not uncommon that after using a fibular flap for lower gum cancer reconstruction, nonunion, chronic osteomyelitis, or fibular bone exposure occurs, which requires a composite bone and soft tissue reconstruction. Radial forearm osteocutaneous flap possesses the risk of stress fracture. Ulnar forearm osteocutaneous flap can be another option for small bone defect reconstruction. Six patients who had undergone fibular flap for mandible reconstructions and sustained either bone exposure (3 patients), chronic osteomyelitis (1 patient), malocclusion (1 patient), or osteoradionecrosis (1 patient) underwent ulnar forearm osteocutaneous flap with 3-cm ulnar bone for touch-up procedure. The distal radioulnar joints were fused with a screw. Six ulnar forearm osteocutaneous flap dissections were also performed on 4 fresh frozen cadavers to clarify the anatomic distribution of the distal ulnar artery. All 6 ulnar forearm osteocutaneous flaps survived with one re-exploration for venous occlusion. All presented bone union. Comparable to the clinical dissection, the cadaveric distal ulnar artery demonstrates a periosteal branch that runs between the proper ulnar nerve and dorsal sensory nerve. This periosteal branch comes out of an ulnar artery approximately 3 cm proximal to the wrist joint. Ulnar forearm osteocutaneous flap can provide a secondary flap of wide skin paddle and small segment bone for specific mandibular defect after a fibular flap transfer.

    To investigate the method of combining radial forearm free flap and adjacent tissue flap in reconstruction of palatomaxillary defects and its effectiveness. Between March 2005 and May 2010, 17 patients with palatomaxillary defects were treated. There were 11 males and 6 females with an age range of 45-74 years (mean, 62.5 years), including 1 case of benign tumor and 16 cases of malignant tumors (7 cases of squamous cell carcinoma of palate, 1 case of recurring squamous cell carcinoma of palate, 1 case of malignant melanoma of palate, 1 case of adenoid cystic carcinoma of palate, 1 case of malignant melanoma of maxilla, 1 case of ductal carcinoma of maxilla, and 4 cases of squamous cell carcinoma of maxilla). The maxillectomy defect ranged from 7.0 cm x 5.5 cm to 10.0 cm x 7.5 cm. According to Brown's classification for the maxillectomy defect, there were type II in 15 cases, type III in 2 cases. Palatomaxillary defects were repaired with radial forearm free flap and buccal fat pad in 11 cases, and with radial forearm free flap, buccal fat pad, and mandibular osteomuscular flap pedicled with temporal muscle in 6 cases. The effectiveness was evaluated after operation by observing the vitality of the flap, the functions of speech, swallowing, breath, and the facial appearance. All cases were followed up 6-12 months without tumor recurrence. All flaps and skin grafts at donor sites survived. The functions of speech, swallowing, and breath were normal without obvious opening limitation. The facial appearance was satisfactory without obvious maxillofacial deformity. No enophthalmos occurred in patients with orbital floor and infraorbital rim defects. The patients had no oronasal fistula with satisfactory oral and nasal functions. According to the type of palatomaxillary defects, it can have good early effectiveness to select combining radial forearm free flap and buccal fat pad or combining radial forearm free flap, buccal fat pad, and mandibular osteomuscular flap for

    The treatment of pressure sores represents a significant challenge to health care professionals. Although, pressure wound management demands a multidisciplinary approach, soft tissue defects requiring reconstruction are often considered for surgical management. Myocutaneous and fasciocutaneous flaps can provide stable coverage of pressure sores. Here, we describe our experience using a recent fasciocutaneous flap, which is named 'reading man' flap, in sacral, ischial, and trochanteric pressure sores. During a period of 1 year the authors operated 16 patients, 11 men, and 5 women, using the reading man flap. The ages of the patients ranged from 24 to 78 years. The location of pressure sores was 8 sacral, 5 ischial, and 3 trochanteric pressure sores. The mean size of pressure sores was 8 cm × 9 cm. All pressure sores covered bt the Reading Man flap healed asymptomatically. After follow-up of 2-8 months, no recurrences were encountered and no further surgical intervention was required. The reading man flap was found to be a useful technique for the closure of pressure sore in different anatomic locations. The advantage of tension-free closure and the minimal additional healthy skin excision made this flap a useful tool in pressure sore reconstructions.

    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.

    Helical rim ear defects can present a reconstructive challenge to the Mohs surgeon. Multiple options exist including wedge excision, helical rim advancement flaps, bilobed flap, and grafts, to name a few. Wedge excision of the ear may result in a noticeable anteverted, smaller ear, and disrupts auricular cartilage with the possibility of chondritis and excess pain. Helical rim advancements can result in anteversion of the ear and a smaller lobule. Mastoid interpolation flaps, which are also called retroauricular to auricular flaps, can be a useful alternative in patients who are willing to return for a second procedure. They are easy to perform and can result in a highly aesthetic reconstruction in which the ear size and form are maintained. The donor skin comes from an area that is hidden from view and heals with minimal complications. We present our suggestions for performing these reconstructions. Ways to optimize results, potential pitfalls, and postoperative care instructions are discussed. Step by step videos are included with this manuscript.

    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.

    Reconstruction of dorsalis pedis with soft tissue is challenging because it needs to preserve thin structure to ensure that the patient will be able to wear shoes. Here, we report the use of a thin superficial circumflex iliac artery perforator (SCIP) flap in dorsalis pedis reconstruction. A 67-year-old man presented with a third-degree burn, which exposed his extensor tendons. A thin SCIP flap from the left inguinal region measuring 15 × 4 cm was transferred to the dorsalis pedis region. Postoperatively, no major cosmetic or functional problems were observed. Because the invasiveness of the donor site is nearly same between SCIP flap and skin graft from inguinal region, SCIP flap is better solution in point of textural qualities for dorsalis pedis reconstruction.

    Full Text Available Eulerian Video Magnification (EVM can enhance subtle changes in videos to reveal what was once invisible to the naked eye. In this proof of concept study, we investigated using EVM as a novel form of free flap monitoring. Free flaps with skin paddles were filmed in the operating room with manipulation of their pedicles. In a representative 77-year-old female who received a latissimus dorsi-serratus-rib composite free flap, EVM was able to detect blockage of arterial or venous supply instantaneously, providing a visible representation through degree of color change in videos. EVM has the potential to serve as a powerful free flap monitoring tool with the benefit of being noninvasive, sensitive, easy-to-use, and nearly cost-free.

    Reconstruction with the latissimus dorsi muscle flap, combined with the serratus anterior fascia flap, was performed to cover two large and separate palmar and dorsal forearm skin defects in a patient, whose hand had been replanted 20 days earlier after traumatic amputation at the distal forearm level. As a result, a total forearm amputation was salvaged by microsurgical replantation and a free combined flap of the subscapular system. This new application of the combined flap allowed the reconstruction of large and separate wounds of the replanted hand, and provided gliding surfaces for tendons.

    Trismus is a frequent complication occurring after treatment of tumors of the pterygomaxillary fossa. Local flaps and full-thickness skin grafts fail to release it because they usually lead to scar contracture in previously irradiated tissues. We propose to release it with a thoracodorsal artery perforator flap, which is feasible in children like other perforator flaps. It is interesting because it is thinner than the anterolateral thigh flap and its scar may be less disgraceful and easier to hide. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    As shown in an earlier work [Vandenberghe, et. al. JFM, Vol 506, 147, 2004], a vertically flapping wing can spontaneously move horizontally as a result of symmetry breaking. In the current experimental study, we investigate the dependence of resultant velocity on flapping amplitude. We also describe the forward thrust generation and how the system dynamically selects a Strouhal number by balancing fluid and body forces. We further compare our model system with examples of biological locomotion, such as bird flight and fish swimming.

    This study was undertaken in an attempt to improve the versatility of the posterior interosseous artery flap (PIA flap) and to decrease flap complication rate. The PIA flap was used for resurfacing 25 cases of the hand and distal forearm over a 2-year period. Observations were made on the anatomy of the PIA flap and its distal reach. Doppler analysis was made a mandatory part of the preoperative planning. Flaps were also raised from the zone of injury if Doppler confirmed the presence of good perforators. No attempt was made to identify the anastomosis between the anterior interosseous artery (AIA) and the PIA prior to flap raising since its presence was ascertained preoperatively with a Doppler and flap raising could begin straightway, saving precious tourniquet time. The surgical technique was further modified to include a large amount of fascia and subcutaneous tissue with the flap. This could perhaps be the reason for survival of larger flaps, absence of venous congestion and the low complication rate seen in our series. These flaps were used to resurface defects involving the dorsum of the hand, palm, distal forearm, wrist and fingers (both dorsal and volar surfaces). The distal reach of the flap was improved by exteriorising the pedicle and bowstringing it across the wrist which was kept in extension. The flap could thus easily reach the distal interphalangeal joint. This exteriorised pedicle was covered with a split thickness skin graft and was divided 3 weeks later under local anaesthesia making it a two-stage procedure. Adipofascial and osteocutaneous PIA flaps were also used depending on the requirement. Out of 25 flaps, 23 were of the adipofascial variety and one each of the fascial and osteocutaneous type. The majority of the patients were between 21 and 30 years old. Trauma was the leading cause of tissue deficit in our series (19/25). Within the trauma group occupational mishap (entrapment of hand in roller machine, presser machine, etc.) was the

    Free anterolateral thigh flaps are a popular flap used for the reconstruction of various soft-tissue defects. From April, 2002 to June, 2003, 32 free anterolateral thigh flaps were used to reconstruct soft-tissue defects. Twenty-three of these flaps were used for lower extremity reconstruction, and nine were used for head and neck reconstruction. There were 24 male and eight female patients, with ages between nine and 82 years. The size of the flaps ranged from 11 to 32 cm in length and 6 to 18 cm in width. Five flaps required reoperation for vascular compromise in four patients and for twisting of the pedicle in another patient. While four of these were salvaged, one flap was lost due to recipient vessel problems. Musculocutaneous perforators were found in 23 cases, and septocutaneous perforators were found in nine cases. In four cases, thinning of the flap was performed. The flap was used as a flow-through type for lower extremity reconstruction in three patients. In two patients, the flap was used as a neurosensory type for foot reconstruction. Eighteen cases underwent split-thickness skin grafting of the donor site and, in the remaining cases, the donor sites were closed primarily. In three patients, the donor areas required a partial skin regrafting procedure. No infections or hematomas were observed. Despite some variations in its vascular anatomy, the anterolateral thigh flap offers the following advantages: 1) it has a long and large-caliber vascular pedicle; 2) it has a wide, reliable skin paddle; 3) it may be harvested as a neurosensory flap; 4) it can be harvested whether its pedicle is septocutaneous or musculocutaneous; 5) it can be designed as a flow-through flap; 6) it can be elevated as a thin or musculocutaneous flap; and 7) the procedure can be performed by two teams working simultaneously, and no positional changes are required.

    To explore the application of alar thin expanded cervical flap with pedicle in anterior neck for large scars on middle and lower face. From February 2000 to July 2013, 26 patients with scars on the middle and lower face were treated with the alar thin expanded cervical flaps with pedicle in anterior neck. After the skin of anterior neck was expanded by implanting skin expanders, alar thin expanded cervical flap with pedicle in anterior neck was obtained with size of 163-275 cm(2). Then the scars on the middle and lower face with the size of 135-196 cm(2) were excised, with the area of excision allowing full coverage of the expanded flap. The flap was rotated and advanced to the middle and lower face, and the incision was closed in layers. The 26 patients were followed up for 2 to 24 months. Twenty-one flaps survived, with good appearance and function. Four flaps showed venous retardation at distal part, and only one flap showed necrosis of the right edge. They were healed by free skin grafting. The alar thin expanded cervical flap not only makes maximum use of expanded flap on the premise of ensuring blood supply, but also guarantees good color, texture, and contour of face and neck.

    Full Text Available The anterolateral thigh flap has been the workhouse flap for coverage of soft-tissue defects in head and neck for decades. However, the reconstruction of multiple and complex soft-tissue defects in head and neck with multipaddled anterolateral thigh chimeric flaps is still a challenge for reconstructive surgeries. Here, a clinical series of 12 cases is reported in which multipaddled anterolateral thigh chimeric flaps were used for complex soft-tissue defects with several separately anatomic locations in head and neck. Of the 12 cases, 7 patients presented with trismus were diagnosed as advanced buccal cancer with oral submucous fibrosis, 2 tongue cancer cases were found accompanied with multiple oral mucosa lesions or buccal cancer, and 3 were hypopharyngeal cancer with anterior neck skin invaded. All soft-tissue defects were reconstructed by multipaddled anterolateral thigh chimeric flaps, including 9 tripaddled anterolateral thigh flaps and 3 bipaddled flaps. The mean length of skin paddle was 19.2 (range: 14-23 cm and the mean width was 4.9 (range: 2.5-7 cm. All flaps survived and all donor sites were closed primarily. After a mean follow-up time of 9.1 months, there were no problems with the donor or recipient sites. This study supports that the multipaddled anterolateral thigh chimeric flap is a reliable and good alternative for complex and multiple soft-tissue defects of the head and neck.

    Carcinological head and neck reconstruction still remains a challenge due to the volume and varied tissues needed. Large and wide oromandibular defects require, not just the bone but also soft tissues for the pelvilingual reconstruction and therefore, a second free flap may become necessary in addition to a fibular flap. The option of an unique chimeric flap based on the fibular artery and its branches is less known whereas it offers the advantage of a unique flap with bone, muscle and multiple skin paddles, independent of each other. The aim of this technical note is to present step by step the surgical procedure of this chimeric flap and share this method that avoids a second free flap.

    Plantar skin has similar histologic features to the palmar area and appears to be the ideal tissue for reconstruction of the palmar region. In this study, an anatomic examination was performed to determine the superficial venous architecture of the instep area, and the use of arterialized venous instep flaps for palmar contracture release was assessed. The anatomical study was performed on 12 fresh cadaver feet. The arterialized venous instep flap, including the skin, subcutaneous tissue and superficial venous plexus, was harvested. To determine the venous structure, dissection (n = 6) and injection-corrosion (n = 6) techniques were used. In the clinical study, nine arterialized venous instep flaps were used for palmar contracture release. All flaps were harvested above the deep fascia and included skin, subcutaneous fat, and the superficial venous plexus. At the plantar site of the flap, two or three veins, one of which was used, were dissected for a sufficient length for the arterial anastomosis. The saphenous vein was used for the venous anastomosis. Dissection and injection-corrosion techniques revealed that the flap had 7-12 and 4-6 veins at its plantar and superior edges, respectively, with numerous anastomoses and interconnections between the veins. The flap dimensions were between 3 × 5 cm and 4 × 6 cm. All flaps survived, with two partial flap necrosis that healed with spontaneous epithelization. No debulking procedures were undertaken and all flaps adapted well to the recipient site. The arterialized venous instep flap is a good alternative to reconstruct palmar contractures by adding similar tissue that is thin and pliable with minimal donor site morbidity.

    Recent developments in autogenous breast reconstruction using the rectus abdominis myocutaneous free flap include attempts to reinnervate the flap tissue. We have carried out anatomical studies to determine the nature of abdominal-wall cutaneous innervation, with particular emphasis on the harvesting of sensate flaps. Dissections were performed on four embalmed and 12 fresh human cadavers (32 sides). The lowest five intercostal nerve trunks were identified and traced to the lateral border of the rectus sheath. A detailed dissection of the intramuscular course of the nerves and associated vasculature was performed. The relationship of the nerves to the vascular perforators used for rectus abdominis myocutaneous flaps was determined visually, and confirmed histologically. In contrast to previous studies, we show that nerves supplying cutaneous sensation can travel with both medial and lateral vascular perforators. In order to confirm clinically useful innervation, the abdominal flap skin of five patients undergoing TRAM flap reconstruction was stimulated electrically, and sensory recordings were made directly from the related intercostal nerve just prior to flap harvest. These studies represent, to our knowledge, the first clinical application of neurophysiological techniques to outline the perforator neurosomes of flaps based on the deep inferior epigastric vascular axis. We provide the first comprehensive study of abdominal-wall innervation with regard to sensate free-flap harvest. Our dissections show complex patterns of abdominal skin innervation that have not been previously described. The implications for sensate free TRAM and DIEP flap reconstructions, as well as the potential for more accurate inclusion of innervated flap skin, are discussed.

    The purposes of this study were to evaluate the clinical application and efficacy of the dorsalis pedis fasciocutaneous flap in the reconstruction of oral cavity defects and to assess the associated donor-site morbidity. From September 2009 to December 2012, 7 patients with associated oral cavity defects resulting from tumor resection underwent reconstruction with a dorsalis pedis fasciocutaneous flap. Surgical anatomy and harvesting procedure of the dorsalis pedis flap are described. Special consideration was given to the associated donor-site morbidity. All flaps survived without any complications. All 7 flaps were based on the dorsalis pedis artery and the greater saphenous vein for perfusion and drainage respectively. In all 7 cases, the donor site was closed with a full-thickness skin graft, with no associated healing complications or functional deficit of the foot. The resulting scar was well hidden in the lower extremity. The dorsalis pedis fasciocutaneous flap is a thin and pliable flap sharing many similarities with the radial forearm flap, thus making it ideal for intraoral reconstruction. Proper intraoperative and postoperative care of the donor site can result in minimal morbidity, as shown in this study. This flap may provide an ideal alternative to the radial forearm free flap, with the added advantages of a well-hidden scar and a high level of patient satisfaction.

    Introduction Oncological resection of the tongue can be reconstructed using a multitude of free flaps. The medial sural artery perforator (MSAP) flap has been well described in the literature in terms of its anatomy and harvest. However, functional outcome studies of post-reconstruction tongue defects using the MSAP flap have not been reported. This study represents the largest outcome study of patients with tongue reconstructions using MSAP flaps and a comprehensive review of its use. Materials and methods From December of 2010 to October of 2015, 579 patients with subtotal glossectomy and free flap reconstructions in Chang Gung Memorial Hospital were retrospectively reviewed. 27 patients were reconstructed with MSAP flap. The pre- and intra-operative factors, as well as flap-related factors were analyzed. Post-operative complications and functional outcomes were evaluated. Donor site assessment were also conducted. Results A 96.3% flap survival rate was found with an average total operating time of 6 hours and 18 minutes. 84.6% of patients had primary closure of the donor site with and the remaining either had skin grafts or delayed closure. Donor site closure can be achieved primarily with no functional deficit. Speech intelligibility remained for most patients. 100% of patients resumed normal oral feeding. Conclusion The MSAP flap is a small to medium sized flap most suited for subtotal glossectomy defects where optimal outcomes can be achieved in terms of speech clarity and restoration of oral intake.

    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 Skin necrosis and wound problems complicate surgical release of severe neglected clubfoot. This is primarily due to excessive tension on the skin edges and a poor understanding of abnormal vascular anatomy in clubfoot. We report a technique of primary skin closure using a local rotation fasciocutaneous flap using the conventional posteromedial skin incision (Turco. Primary uncomplicated wound healing was achieved within 2 weeks in all 16 rigid and neglected clubfeet (1-7 years operated by this technique. This flap is scientifically logical, technically easy and ensures primary wound healing.

    Muscle and musculocutaneous flaps have been used reliably in reconstruction of soft-tissue defects for many years. Previous experimental studies have shown musculocutaneous flaps to be superior to the random pattern and fasciocutaneous flaps in the management of infected wounds. Over the past decade, perforator flaps have gained acceptance as alternative methods of reconstruction in the clinical setting that can decrease donor-site morbidity and hospital stay, and increase patient satisfaction. The authors theorized that perforator flaps may be able to handle infected wounds better than random pattern and fasciocutaneous flaps because their blood supply is essentially the same as many of their musculocutaneous counterparts. The goal of this study was to compare the S1 perforator-based skin flap and latissimus dorsi musculocutaneous flap in the dorsal flank of the rabbit with the introduction of bacteria to simulate both superficial and deep wound infection. Measurements of oxygen tension and regional perfusion index were performed on both types of flaps to ascertain their viability and capacity to heal. The authors found no statistical significance between latissimus dorsi musculocutaneous and S1 perforator flaps in the rabbit with respect to superficial and deep wound infections. The regional perfusion index was calculated for postoperative days 1, 2, and 4. No statistically significant difference between the two flaps using the regional perfusion index could be identified. Additionally, regional perfusion for both types of flaps was greater than 0.6, indicating that their capacity to heal wounds is similar.

    Inadequate venous drainage can lead to congestion and necrosis of flaps used in the repair of defects, thereby elevating the risk of flap failure. In this study, we sought to test the hypothesis that the venous drainage was better in flow-through flaps than in conventional dorsalis pedis free flaps used in the repair of dorsal foot defects. In this retrospective study, we investigated the data of 14 patients who underwent repair with flow-through flaps (n = 7) or conventional flaps (n = 7) for dorsal foot defects, between January 2007 and December 2013. The defects ranged from 6.2 × 11 cm to 9.5 × 16 cm in size. The donor sites were resurfaced using full-thickness free-skin grafts, and after transfer, the flaps were evaluated for postoperative congestion, surviving area, and sensory function. The results showed that the operative time was significantly longer for flow-through flaps than for conventional flaps (6.4 ± 1.7 h vs. 4.3 ± 1.2 h, P = 0.020), mainly due to additional dissection of the first dorsal metatarsal artery required in the case of the former. Necrosis was observed in the case of 4 conventional flaps, but not in the case of flow-through flaps. The flow-through flaps showed significantly lower incidence of congestion and higher survival area proportion than the conventional flaps (P dorsalis pedis flaps have the advantages of lower incidence of necrosis and congestion and better survival over the conventional flaps in the repair of dorsal foot defects, and absence of additional morbidities, but required a longer operative time than conventional flaps.

    The authors conducted a two-part study to determine whether transcutaneous oxygen pressure (TcPO (2)) and transcutaneous carbon dioxide pressure (TcPCO (2)) can be used to monitor flap viability after transplantation. The first part was an animal study in which TcPO (2) and TcPCO (2) were measured in 10 epigastric island flaps subjected to arterial or venous ischemia. The second part was a clinical study in which both were measured in 27 free skin flaps. In the experimental study, TcPO (2) decreased to nearly 0 mmHg after 10 minutes of arterial and venous ischemia. TcPCO (2) increased to 100 mmHg after 60 minutes of either type of ischemia. In the clinical study, congestion was suspected in six flaps on the basis of clinical signs alone. Three congested flaps with TcPCO (2) more than 90 mmHg were selected for intervention. The remaining three congested flaps, with TcPCO (2) 80 mmHg or less, survived completely without further treatment. The TcPO (2) of all treated flaps and of the six flaps not requiring further treatment was 0 mmHg. Results of experimental study indicate that TcPO (2) is more sensitive than TcPCO (2) to flap ischemia. However, results of clinical study suggest that it is very hard to distinguish congested flaps from healthy flaps by TcPO (2) alone. The authors believe that a congested flap with a TcPCO (2) more than 90 mmHg requires further treatment.

    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

    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

    Ischemic complications after nipple-sparing mastectomy (NSM) have been associated with numerous variables. However, the impact of NSM flap thickness has been incompletely evaluated. NSM flap thickness was determined for all NSMs from 2006 to 2016 with available pre- or postoperative breast magnetic resonance imaging (MRIs). Demographics and outcomes were stratified by those with and without ischemic complications. Of 1,037 NSM reconstructions, 420 NSMs had MRI data available, which included 379 preoperative MRIs and 60 postoperative MRIs. Average total preoperative skin/subcutaneous tissue NSM flap thickness was 11.4 mm. Average total postoperative NSM flap thickness was 8.7 mm. NSMs with ischemic complications were found to have significantly thinner overall postoperative NSM flap thickness compared with those without ischemic complications (P = 0.0280). Average overall postoperative NSM flap thickness less than 8.0 mm was found to be an independent predictor of ischemic complications (odds ratio, 6.5263; P = 0.026). In NSMs with both pre- and postoperative MRIs, the overall average postoperative NSM flap thickness was 68.2% of preoperative measurements. Average overall postoperative NSM flap thickness was significantly less than average overall preoperative NSM flap thickness (P < 0.0001). NSMs with ischemic complications were found to have a significantly lower ratio of overall postoperative to preoperative flap thickness (52.0% versus 74.0%; P < 0.0001). Ischemic complications after NSM are significantly associated with thinner postoperative NSM flap thickness. Particularly, NSM flap thickness less than 8.0 mm is a positive independent predictor of ischemic complications. The ratio of postoperative to preoperative NSM flap thickness was significantly lower in reconstructions with ischemic complications.

    A posterior upper arm flap based on the profunda brachii vessels has been described to cover soft-tissue defects in the upper anterolateral chest. In our series, the posterior upper arm skin is elevated with the long head of the triceps muscle to cover seven chest-wall defects resulting from indolent postradiation open wounds following partial TRAM flap failure (n = 2), soft-tissue deficiencies following partial TRAM flap loss (n = 3), and primarily as an ancillary flap in TRAM flap breast reconstruction (n = 2). This flap also may be used to supply well-vascularized tissue in the regions of the shoulder, axilla, and posterolateral back. A prerequisite for this operation is redundant tissue of the upper arm often present in middle-aged women and in patients with lymphedema following mastectomy. In our series of seven patients, all donor sites were closed primarily, and there was no subjective functional deficit following transfer of the long head of the triceps muscle.

    Objective: To evaluates mandible reconstruction by free vascularized fibular flap with special emphasis on the immediate complications. Methods:The clinical data of 63 patients were reviewed, 35 male and 28 female(age range l6 to 73 years). Aesthetic and functional outcomes were evaluated by follow-up and/or telephone conversation. Results:Among the 63 fibular flaps, 29 were osteocutaneous flaps with one or two skin islands. All the flaps were surviving well and the success rate was 100%. Long term donor site disability was not recorded for any patient. Thirty-one patients responded for aesthetic and functional evaluation, 20 cases(64.5%) reported their facial appearance as excellent or good, 11 (35.48%) felt fair; 14 cases (45%) could eat unrestricted diet, 17(55%) could eat soft diet; 21 cases were(67.67%) speech normal, 10(22.33%) speech intelligible. Conclusion:Free fibular flap reflects good functional and esthetic results with a high degree of consistency, and acceptable level of complications, and we strongly believe the vascularized fibular flap is the first choice for mandibular reconstruction.

    Improvement of flap survival represents an ongoing challenge in reconstructive surgery. The angiogenic potential of adipose-derived stem cells (ASCs) offers a promising approach to improve the viability of random pattern flaps. Recently, to maximize the therapeutic effects of ASCs, increasing focus is being placed on how to deliver the stem cells to target lesions. The purpose of the present study was to compare the effectiveness of different administration routes of ASCs to improve the viability of the random pattern skin flap. ASCs labelled with PKH26 were applied via four methods to the cranially-based random pattern skin flaps of rats: (a) intravenous injection; (b) subcutaneous injection; (c) application with collagen sponge seeding; and (d) application with fibrin glue seeding. ASCs led to a significant increase in flap viability in the subcutaneous injection group and the collagen sponge group. Cutaneous blood flow was increased in the intravenous injection, subcutaneous injection and collagen sponge groups. Capillary density in the intravenous injection group and collagen sponge group was significantly greater than in the control group (no treatment). PKH26-positive cells via the collagen sponge were distributed more densely within the flap than in other groups. This study demonstrated that the collagen sponge method delivered ASCs most effectively within the flap and increased flap vascularity. The clinical therapeutic effects of ASCs can therefore be maximized when the optimal delivery route is chosen.

    The objective of this study was to show the use and effectiveness of nasal alar rim flap on the correction of unilateral cleft lip nasal deformity. Thirty-one patients (age range, 10-29 years; mean, 15.1 years; 14 male and 17 female patients) with unilateral cleft lip underwent rhinoplasty surgery using alar rim flap. The excessive skin of nasal alar was marked, then a skin flap was raised. This flap can be transferred medially (type 1) or laterally (type 2) to narrow the nostril or to augment the nasal sill and, of course, to correct the alar web deformity. Preoperative and postoperative photographs were measured for photogrammetric analysis in 16 patients. The alar rim flap used in patients with unilateral cleft lip made the nostrils more symmetrical. The nostril sill was augmented with flap type 1. The alar base width was narrowed with flap type 2 (P = 0.03). The alar web deformity was corrected. The alar rim flap could be an ideal treatment option for correction of alar web deformity in patients of unilateral cleft lip.

    We aimed to evaluate the role of a synthetic somatostatin analogue in delay procedure of experimental skin flaps. Thirty-six rats were randomly divided into 2 groups of 18 each to compare the possible local ischemic effect of octreotide with that of surgical delay in the dorsal random pattern skin flap model. The inducible nitric oxide synthase gene expression was assessed in the flap territory at intervals of immediate, 24 and 48 hours after preconditioning. Histologic analysis was performed in rats at 48th hour and 3 additional rats were used for microangiography. A gradual increase of daily transcript levels was detected in both groups (P < 0.05). The differences of molecular and histologic findings between the groups were not distinctive. Pharmacologically preconditioned rat displayed relevant microvascular features. Forty rats were further grouped randomly into 4 groups of 10 each. In group 1 rats, flaps were raised and reinserted without any prior intervention. Group 2 rats underwent surgical delay procedure, whereas flap territories of the others received either saline solution or octreotide 1 week before the ultimate flap harvest. After another 7-day period, both delay procedures were found effective in improving flap viability (P < 0.01). Ischemia induced by octreotide favored to investigate its utility in delay phenomenon. Although it was not as effective as the surgical delay procedure, it may be a safe pharmacologic alternative to improve the flap survival.

    To improve skin flap healing, one promising strategy in reconstructive surgery might be to optimize platelet rich plasma (PRP) bioactivity and the ischemia-altered expression of genes. We studied both the effect of PRP on ischemic flaps, and whether in vivo bioluminescence imaging (BLI) is a suitable method for the longitudinal monitoring of angiogenesis in surgical wounds. Axial murine skin flaps were created in four experimental groups. In vivo measurements of VEGFR2 expression levels were made every other day until the 14th day. The local VEGF level and microvessel density were quantified on the 14th day via ELISA and immunohistochemistry, and flap survival rates were measured. We demonstrated that PRP and induced ischemia have a beneficial influence on angiogenesis and flap healing. Combining the two resulted in a significantly robust increase in angiogenesis and flap survival rate that was corroborated by bioluminescence imaging of VEGFR2 activity. This study shows that angiogenic effects of PRP may be potentialized by the stimulus of induced ischemia during free flap harvesting, and thus the two procedures appear to have a synergistic effect on flap healing. This study further demonstrates that BLI of modulated genes in reconstructive surgery is a valuable model for longitudinal in vivo evaluation of angiogenesis.

    Fingertip amputation is the most common type of injury in the upper limb. Goals in fingertip amputation reconstruction are covering the defect, establishing maximum tactile gnosis, keeping the length of the finger, protecting the joint function, acquiring a well-padded pulp tissue, providing a bed for growing nail, obtaining a satisfactory cosmetic appearance and allowing the patient to return to work as soon as possible. Adjacent skin and soft tissue are the best covers for fingertip injuries. However, local homodigital flaps lack enough tissue to cover the defect. To solve this problem, we used V-Y rotation advancement flap bilaterally in fingertip amputations which meets all the reconstruction goals. Rotation besides advancement makes this flap more mobile and easier to cover larger defects in all amputation planes. Between 2007 and 2009, we performed bilateral V-Y rotation advancement flap on seven male patients' pulpa (average age, 37.6 years) whose fingertips were not replantable. Fourteen flaps were made on 7 fingers. There was neither total nor partial flap loss. Patients had neither cold intolerance nor scar hypersensitivity. Stiffness of the PIP joint did not occur. No obvious hooked nail occurred in patients who have remaining nail matrix. Because flaps contain neurovascular bundle, there was no difference in sensation and perfusion between the finger's pre-operative and post-operative status. The result was satisfactory with painless pinching. In addition to the various and versatile fingertip reconstruction methods, we want to present V-Y rotation advancement flap as a quick, reliable and aesthetic method.

    Full Text Available Reconstructive surgery for breast cancer are an integral method of rehabilitation of cancer patients. Breast reconstruction may be delayed and instantaneous. The article presents a description of the thoraco-epigastric flap for breast reconstruction in cancer. The operation involves the replacement of the remote volume (after radical resection of the breast and the breast skin adjacent tissues adjacent to the inframammary crease from the side of the anterior abdominal wall. Surgery is indicated when the tumor in the lower parts of the breast, closest to the skin, in combination with small size breast cancer. The article presents a clinical example of this operation. Described in detail the operation, received a good cosmetic result. The advantage of the application of thoraco-epigastric flap is in the simplicity of the technique of its execution, good blood supply, donor wound is easily sutured due to the possible wide separating cellular adjacent skin and subcutaneous tissue. The disadvantage of this method is limited and the need for careful monitoring of perforating branches of the upper epigastric artery. Thus, thoraco-epigastric flap, can be applicable when performing reconstructive operations for breast cancer in compliance with the necessary requirements for the formation of the flap and the correct attitude to feeding the flap vessels, and virtually eliminates possible complications with the healing of the flap. Undoubtedly, reconstructive plastic surgery for breast cancer, during the testimony and technical capabilities, are an essential component of surgical treatment.

    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.

    Prosthetic-based breast reconstruction can be used in combination with autologous flaps such as a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TDAP) flap to achieve symmetry. However, the LD and TDAP flaps require a different skin incision from that which is used for the mastectomy. As a new autologous flap for use in combination with prosthetic-based breast reconstruction after nipple-sparing mastectomy (NSM), we used an inframammary adipofascial flap. The patient was a 27-year-old female with moderate ptotic breasts, who had ductal carcinoma in situ in the lower outer quadrant of her left breast. After NSM through the inframammary fold (IMF) incision, the subcutaneous fat of the intended inframammary area was undermined, and the tongue shaped adipofascial flap was pulled up in the intended area. After inserting a tissue expander under the major pectoral muscle, this adipofascial flap was reflected back to the inferior portion of the breast area. After modeling the breast mound with this flap, the inframammary skin incision was sutured. Eleven months later, the patient underwent surgery to replace the expander with a permanent implant. Eight months after the replacement with an implant, the cosmetic result is good. This procedure can be performed through the same skin incision on the IMF as NSM. Total breast reconstruction using the inframammary adipofascial flap with an implant can be an alternative approach to achieving symmetry in some patients. This method is useful for breast reconstruction after NSM for young patients with moderate-ptotic breasts. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  12. New Possible Surgical Approaches for the Submammary Adipofascial Flap Based on Its Arterial Supply

    2016-01-01

    Full Text Available Introduction. Submammary adipofascial flap (SMAF is a valuable option for replacement of the inferior portion of the breast. It is particularly useful for reconstruction of partial mastectomy defects. It is also used to cover breast implants. Most surgeons base this flap cranially on the submammary skin crease, reflecting it back onto the breast. The blood vessels supplying this flap are not well defined, and the harvest of the flap may be compromised due to its uncertain vascularity. The aim of the work was to identify perforator vessels supplying SMAF and define their origin, site, diameter, and length. Materials and Methods. The flap was designed and dissected on both sides in 10 female cadavers. SMAF outline was 10 cm in length and 7 cm in width. The flap was raised carefully from below upwards to identify the perforator vessels supplying it from all directions. These vessels were counted and the following measurements were taken using Vernier caliper: diameter, total length, length inside the flap, and distance below the submammary skin crease. Conclusions. The perforators at the lateral part of the flap took origin from the lateral thoracic, thoracodorsal, and intercostal vessels. They were significantly larger, longer, and of multiple origins than those on the medial part of the flap and this suggests that laterally based flaps will have better blood supply, better viability, and more promising prognosis. Both approaches, medially based and laterally based SMAF, carry a better prognosis and lesser chance for future fat necrosis than the classical cranially based flap.

    Summary: We report a case of a young double-hand allotransplant patient who presented with a full-thickness skin necrosis of the dorsum of the left hand after vascular compromise of the allotransplantation. Considering the lack of viable dorsal tissue overlying the extensor tendons and the need for early hand rehabilitation, an ultrathin pedicled groin flap was used for the coverage. This procedure resulted in salvaging the allotransplantation, and the patient was able to successfully return to work after his surgery. To our knowledge, this is the only case of an upper extremity allotransplant salvaged by a pedicled flap.

    Degloved mutilated hand injury results in severe contracture of palmar surfaces after avulsion defects of soft tissue and insensate scarring of amputated digits at the proximal interphalangeal level. In an effort to restore the basic function of such hands, we simultaneously used a sensate in-step free flap for re-surfacing the first web space and sensate twin digital free flaps for re-surfacing the palmar defects of the thumb and index finger. Three male patients sustained degloved mutilated hand injury from a machine in a factory. The average age of the patients was 26 years. These injuries were reconstructed by concomitant twin digital neurovascularised free flaps harvested on the contralateral hands and the in-step neurovascularised free flaps harvested on the feet. The lateral plantar vascular pedicle of the in-step flaps was anastomosed to the vascular pedicle of the twin digital flaps by a flow-through fashion. All flaps survived. These flaps provided durable sensate coverage and improved pinch and grasp. The morbidity of donor fingers and feet was minimal. These described flaps supply durable glabrous sensate skin of prehensile function in degloved mutilated hands. Our method is useful in the reconstruction of degloved mutilated hands with amputated stumps of the thumb and counter digit more than 3 cm in length required for pinch and grip.

    Currently the radial forearm fasciocutaneous flap and the anterolateral thigh flap are among the most popular free flaps used for reconstruction of oral soft tissue. However, there is controversy about their efficacy after reconstruction of tongue defects because of their respective intrinsic properties, so we have compared them in reconstruction of tongue defects using meta-analysis. We conducted a search in Pubmed, EMBASE, OVID, Science Direct, the Cochrane Library, and Chinese National Knowledge Infrastructure, which covered all papers published before January 2015. Twelve clinical papers, that included 366 patients with 198 radial forearm flaps and 168 anterolateral flaps, met the criteria. Relevant data were extracted and analysed using systematic meta-analyses. The results showed that the incidence of localised numbness at the donor site of the radial forearm flap postoperatively was significantly higher and satisfaction with the appearance of the donor site significantly lower than in the anterolateral thigh group. There were no differences in flap survival, incidence of vascular crises in the flap, complications, satisfaction with the appearance of the tongue, or the postoperative clarity of speech and swallowing ability. Results suggested that the anterolateral thigh flap is the ideal soft tissue flap for reconstructing defects in the tongue, as there was minimal numbness at the donor site and patients were much more satisfied. Further research is needed to address details of the site and the extent of surgical defects as well as the relations between dissection of the radial flap and repair of the skin graft.

    transplantation. Methods Between October 2007 and June 2012, 9 female patients with serious scalp avulsion and large skull exposure were treated, aged 23-54 years (mean, 38 years). The injury causes included machine twist injury in 6 cases, traffic accident injury in 2 cases, and falling from height injury in 1 case. Before admission, 3 patients had scalp necrosis after scalp in situ replantation, and 6 patients underwent debridement and dressing. The time from injury to admission was 8 hours to 7 days (mean, 1 day). The avulsed scalp area ranged from 75% to 90% of the scalp area (mean, 81%); the exposed skull area ranged from 55% to 70% of the scalp area (mean, 63%). Two patients had unilateral auricle avulse. CTA was used to observe the superficial temporal artery and vein, facial artery, external jugular vein, dorsal thoracic artery and vein, and measure the blood vessel diameter before operation. According to the CTA results, the latissimus dorsal skin flaps were desinged to repair wounds in 7 cases, the latissimus dorsal muscle flaps combined with skin graft were used to repair wounds in 2 cases. According to preoperative design, operation was successfully completed in 7 cases; great saphenous vein was used as vascular graft in 2 cases having poor images of superficial temporal vessels. The size of latissimus dorsal skin flaps ranged from 20 cm × 14 cm to 25 cm × 20 cm; the donor site was repaired with skin graft. The size of latissimus dorsal muscle flaps were 23 cm × 16 cm and 16 cm × 10 cm; the donor site was directly sutured. Results The blood vessel diameter measured during operation was close to the value measured before operation. The operation time was 6-8 hours (mean, 6.5 hours). The latissimus dorsal muscle (skin) flap and skin graft survived, with primary healing of wound or incision at donor site. The patients were followed up 3 months-2 years (mean, 6 months). The flap had soft texture and skin had no ulceration. Conclusion The free latissimus dorsi flaps

    To evaluate the effectiveness of different flaps for repair of severe palm scar contracture deformity. Between February 2013 and March 2015, thirteen cases of severe palm scar contracture deformity were included in the retrospective review. There were 10 males and 3 females, aged from 14 to 54 years (mean, 39 years). The causes included burn in 9 cases, hot-crush injury in 2 cases, chemical burn in 1 case, and electric burn in 1 case. The disease duration was 6 months to 6 years (mean, 2.3 years). After excising scar, releasing contracture and interrupting adherent muscle and tendon, the soft tissues and skin defects ranged from 6.0 cm x 4.5 cm to 17.0 cm x 7.5 cm. The radial artery retrograde island flap was used in 2 cases, the pedicled abdominal flaps in 4 cases, the thoracodorsal artery perforator flap in 2 cases, the anterolateral thigh flap in 1 case, and the scapular free flap in 4 cases. The size of flap ranged from 6.0 cm x 4.5 cm to 17.0 cm x 7.5 cm. All flaps survived well. Venous thrombosis of the pedicled abdominal flaps occurred in 1 case, which was cured after dressing change, and healing by first intention was obtained in the others. The mean follow-up time was 8 months (range, 6-14 months). Eight cases underwent operation for 1-3 times to make the flap thinner. At last follow-up, the flaps had good color, and the results of appearance and function were satisfactory. Severe palm scar contracture deformity can be effectively repaired by proper application of different flaps.

    Full Text Available Background: The facial asymmetry correction in complex craniofacial malformations presents a challenging problem for reconstructive surgeons. Progressive hemifacial atrophy (HFA and hemifacial microsomia (HFM can manifest in different grades of severity. Most patients require only soft-tissue augmentation. Free flaps are the best option for correction of severe facial soft-tissue deficiency. Materials and Methods: Twenty-two patients of HFM and HFA were included in this study from January 2006 to March 2009 in the Department of Plastic and Reconstructive Surgery, SMS Medical College and Hospital. In all cases, atrophy correction was done using de-epithelialised parascapular free flap with the de-epithelialised surface was placed under the skin. A small skin paddle was taken for monitoring. Results: All cases were reconstructed with de-epithelialised parascapular free flap. There was no flap loss in this series. Hematoma was noted in five cases. Debulking and removal of skin paddle were done in all cases after 6 months. Atrophy recurrence was not observed in any of the cases on follow-up. Conclusion: Contouring of face in cases of HMF and HFA is satisfactorily done with the parascapular free flap. It gives better cosmetic results with minimal donor site morbidity. Facial vessels are better recipient vessels for anastomosis. Keeping de-epithelialised surface of flap under the skin helped in preventing sagging.

    Medical examiners often have to solve questions such as firing distance and bullet trajectory for lethal weapons. Knowledge in the field of terminal ballistics has increased during the last 30 years and layer by layer dissection reveals superficial wounds that can be linked with the permanent cavity. At the end of the 1990s, terminal ballistics also focused on less lethal weapons and their wounds. Here, 2 different less lethal weapons with single bullets were tested on nonembalmed and undressed cadavers (N = 26) at different ranges and speeds. We have developed a technique for dissection which we call flap by flap dissection that reveals the advantage of the bullet-skin-bone entity, the absence of wounds linking its components and range of less lethal weapons.

    Full Text Available The anterolateral thigh (ALT flap is now widely established as a versatile flap which can provide ample amounts of skin, muscle and fascia to construct a variety of defects following major head and neck surgery. However, its use remains cautious due to well documented variations in its vascular anatomy for which this flap is notorious. What is less well known is the effect of variations in quadriceps muscle anatomy on the success of flap harvest. Here, we report a unique case in which fusion of the vastus intermedius (V.I and vastus lateralis (V.L muscles precluded ALT flap harvest. We also advise on appropriate management should similar cases be encountered. To our knowledge this is the first reported case of its kind in the English language literature.

    Full Text Available The treatment of breast cancer (BC is a relevant problem. Surgery is a key treatment method for BC. The volume of its operations varies from radical mastectomies to lumpectomies and, in the areas of regional metastases, from three-level lymphadenectomy to sentinel lymph node biopsy. Objective: to assess whether a displaced TRAM flap may be used for reconstructive operations for BC. The paper presents some experience in treating 11 BC patients in whom a displaced TRAMP flap was employed for reconstruction. At this time, the displaced TRAM flap was applied for delayed reconstruction in 3 patients. The mean age of the patients was 45.5 ± 15.7 years. In 8 BC patients undergoing one-stage reconstruction with a displaced TRAM flap, the treatment schedule was as follows: surgical treatment in 1 patient, combined treatment in 2 patients, and multimodality treatment in 5. The patients received targeted therapy in 3 cases or hormone therapy in 6. A lower abdominal skin-and-fat flap on one vascular pedicle was used in all the 11 patients.Indications for using a displaced TRAM flap were determined; complications were analyzed. The percentage of complications due to the use of a displaced TRAM flap was 9.1 % in our study.To reduce the rate of complications after breast reconstruction with a displaced TRAM flap, we carefully selected patients for this choiceof a plastic component. The displaced TRAM flap is one of the variants for delayed breast reconstruction despite its duration and complexity. Corrective surgery is further used to achieve breast symmetry. Corrective operations, namely, breast liposuction and submammary fold formation, were performed in 2 patients. For full breast recovery, the nipple-areolar complex is to be formed following skin-sparing mastectomies and delayed breast reconstructions. The cosmetic effect was evaluated in 11 patients as excellent in 4 (36.4 % cases, good in 7 (63.6 %. Neither local recurrences nor distant

    After Koshima and Soeda first described perforator flaps in 1988, Wei has improved the technique by describing the "free style perforator flap". These flaps have the advantage of being performed on all skin perforators and in reducing donor site morbidity. The disadvantage, however is that the size of their angiosome is not defined and the evaluation of their relay on the experience of the surgeon. An evaluation of the size of an angiosome by conducting intraoperative angiography is proposed. Intraoperative angiography is performed after injection of indocyanine green. Stimulation of the indocyanine green by infrared causes the emission of fluorescent radiation. This fluorescence is then detected by a specific camera that displays real-time visualization of the skin's perfusion. We present the case of a 39-year-old patient who had an open tibial pilon fracture, for which we performed a pedicled propeller flap based on a posterior tibial perforator. Angiography was used to determine accurately the optimal skin perfusion of the propeller flap, which was based on a perforator from the posterior tibial artery. Angiography identified several levels of skin perfusion with a high fluorescence, intermediate and absent. The non-vascularized part of the skin paddle was resected. Given the unreliability of this technique, hypoperfused area was retained. Debridment of this area, however was necessary at day 5 postoperative with repositionning of the flap. Indocyanine green angiography may be a useful decision-making tool for intraoperative surgeon. It allows to adjust the size of the propeller flap's skin paddle to it angiosome. However, this evaluation method needs to be improved with the introduction of a quantitative threshold.

    The purpose of this study was to evaluate tongue function and donor site morbidity in patients with oral cancer surgically treated and reconstructed with radial or anterolateral thigh free flaps. Twenty patients underwent primary reconstruction after hemiglossectomy between January 2002 and June 2004. Ten patients were reconstructed using a free forearm flap and the remaining with an anterolateral thigh flap. Eight patients on each group underwent postoperative radiotherapy (average, 60 Gy). All of them were followed postoperatively to determine after 6 months their functional outcome as it related to speech, deglutition, tongue mobility, and donor site morbidity. The intelligibility, deglutition, and tongue mobility were each scored on a scale ranging from 1 to 7 by an independent investigator. Data were analyzed by the 2-tail Mann-Whitney U test. No differences in mean speech intelligibility, tongue mobility, or deglutition mean scores were seen between radial forearm flap and anterolateral thigh flap (P > .05). In all anterolateral thigh flap-treated cases, the donor site was closed directly and no complications were seen. However, in all forearm flaps donor site closure was carried out with skin grafts and dorsal forearm splinting was applied for 1 week postoperatively. In 4 cases a partial skin graft failure was observed and donor sites healed for second intention. Anterolateral thigh flap, with its versatility in design, long pedicle with a suitable vessel diameter, and low donor site morbidity, could be the ideal flap for hemiglossectomy defect reconstruction.

  7. The tumbling concha-cartilage flap for correction of lop ear.

    2000-08-01

    This article presents a new surgical method that uses tumbling concha-cartilage flaps to correct lop ears. Through a posterior or anterior auricular skin incision, a rectangular or T-shaped cartilage flap is elevated from the concha and tumbled backward. After passing under the postauricular skin, the flap's tip is fixed to the lidded helix or scapha. The recoiling force of the flap's conchal side enables the lidded portion to be in a normal, erect, anatomic position. The method also increases the vertical height of the ear and creates a normally shaped scapha. Sixteen lop ears were corrected using this procedure, with most of them maintaining natural auricular features. Therefore, this method was considered effective for the correction of moderate lop ear deformity.

    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.

    Deep sternal wound infection (DSWI) is a grave complication of median sternotomy, associated with high morbidity, mortality and escalating treatment costs. There is general consensus that optimal treatment comprises radical debridement followed by coverage with a vascularised flap. However, there is ongoing debate regarding the ideal operative procedure. We present our experience with the infraareolar pectoralis major island myocutaneous flap (PEC-MI flap) as treatment of first choice in DSWI. Following a retrospective chart review, data pertaining to patient demographics, type of cardiac surgery performed, prevalence of known DSWI risk factors, identified pathogens, duration of surgery, flap-related complications, duration of hospital stay and antibiotic therapy, as well as mortality were noted. Additionally, we describe the operative technique and review the relevant literature. Twenty-five patients underwent coverage with the PEC-MI flap in our department. The average age was 69.2 years. Nineteen patients underwent coronary artery bypass surgery, 10 valve replacement, two aortic replacement surgery and one pericardiectomy. In six cases, no internal mammary artery was used in cardiac surgery, in 11 cases one and in seven cases both internal mammary arteries were used. The average duration of surgery was 154.2 min and the average hospital stay was 28.4 days. Complications which required revision surgery were haematoma in three cases, one wound dehiscence and one recurrent infection. Two cases required coverage with an additional regional flap. The PEC-MI flap has been used as flap of first choice in our clinic for treatment of DSWI. It is sufficient to raise the flap unilaterally, and it does not require skin grafting. The combination of immunocompetent bulky muscle tissue used to obliterate the sternal cavity and the large skin paddle enabling a low-tension skin closure allows reliable and efficient treatment of this severe complication.

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

    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.

    Partial skin and fat necrosis is the most common complication occurring in TRAM flaps. It is related to disturbances of the microcirculation and oxygenation in the contralateral part of the flap. It may be hypothesised that the development of necrosis is promoted by the vasoconstrictor endothelin, the production of which is enhanced in ischaemic flap tissues. The purpose of this study was to evaluate the effect of tezosentan, a new endothelin receptor blocker, on microcirculation and oxygenation in experimental TRAM flaps. The administration of tezosentan began preoperatively (3 mg/kg body weight) and then continued at a rate of 1.5 mg/kg/h. A TRAM flap with a skin island measuring 16 x 8 cm was raised in the middle of the epigastrium in minipigs. The flap was pedicled on the right superior epigastric vessels. Microcirculatory blood flow was measured with laser Doppler flowmetry and tissue oxygen tension was measured with a Clark-type microprobe. Dominant subcutaneous veins were cannulated in both the ipsilateral and the contralateral parts of the flap. Subdermal tissue oxygen tension in the contralateral part of the flap was significantly reduced 4h after surgery to 5 mmHg (ca. 48 mmHg in normal tissue) in the control group, but to only 12 mmHg in the group that had been administered tezosentan (Peffluent of the contralateral part of the flap, although microcirculatory blood flow remained virtually unchanged. Our findings suggest that tezosentan improves oxygenation and metabolism in the jeopardised contralateral flap tissue, probably as a result of a decrease in venous vascular resistance and fluid extravasation.

    The tubed, buried anterolateral thigh (ALT) flap is a popular reconstruction method for total pharyngolaryngectomy defects. The "papillon"-designed ALT flap, described by Hayden et al, offers an alternative method of using the ALT flap in this situation. We report our early experience with the papillon ALT flap in a patient cohort. On retrospective review, all patients who underwent reconstruction of circumferential total pharyngolaryngectomy defects with the papillon ALT flap from February 2012 to February 2015 were identified from our departmental database. Demographic and clinical data, operative details, and complications were analyzed from the records. Seven patients were included in this study. The mean length of hospital stay was 15 days (range, 10 to 32 days). Acute complications occurred in 5 of 7 patients, namely, partial flap loss managed by a pectoralis flap (1 of 7 [14%]); an early pharyngocutaneous fistula (4 of 7 [57%]) managed by simple repair, wound packing, or delayed repair; and a donor-site hematoma (1 of 7 [14%]). At follow-up (range, 2 to 24 months), there was 1 stricture formation, but no chronic fistula. All patients were able to swallow orally. Early results using the papillon ALT flap suggest that this technique is a viable alternative to the standard tubed ALT flap design. The advantages of this design include the following: 1) it offers simultaneous vascularized skin to resurface anterior neck skin deficiency without resorting to additional tissue elsewhere; 2) direct monitoring of the ALT flap is possible; and 3) any pharyngocutaneous fistula is exteriorized to the surface without compromising the internal neck structures and can be easily identified and repaired directly in the office.

    The optimal method for surgical management of subglottic stenosis is based upon careful assessment of the location, caliber, length, and maturity of the stenotic segment, as well as associated conditions. For patients with a mature stenosis of short length, excision of the anterior arch of the cricoid and first ring and immediate reconstruction by means of a sliding flap of the next two to three rings of trachea offer a one-stage definitive treatment without the need for grafting. We report four cases of subglottic stenosis and one case of cricoid chondroblastoma in which reconstruction of the airway was successful and prompt. For carefully selected cases, sliding flap tracheoplasty may be a useful alternative to procedures in which the airway is expanded by means of grafting.

    To study the methods and effectiveness of repairing degloving injury of the distal phalanx with homodigital bilobed flaps tiled. Between April 2008 and June 2011, 40 patients (40 fingers) with degloving injury of the distal phalanx were treated, which were caused by machine. There were 30 males and 10 females, aged from 18 to 56 years (mean, 30 years). The time from injury to operation was 1-5 hours (mean, 2.5 hours). Affected fingers included index in 13 cases, middle finger in 11 cases, ring finger in 9 cases, and little finger in 7 cases. The defect area ranged from 3.0 cm x 2.0 cm to 5.5 cm x 3.8 cm. All cases complicated by pollution and exposure of tendon and phalanx, 5 cases by phalangeal fractures, and tendon insertion had no rupture. The end dorsal branches of digital artery island flaps and digital arterial island flaps were used in 14 cases, the end dorsal branches of digital artery island flaps and near dorsal branches of digital artery island flaps in 18 cases, and the end dorsal branches of digital artery island flaps and superficial palmar digital veins arterilization island flaps in 8 cases. The area of the upper flaps ranged from 2.0 cm x 1.5 cm to 2.6 cm x 2.2 cm and the area of the next leaf flaps ranged from 2.5 cm x 2.0 cm to 3.5 cm x 2.5 cm. The donor sites were covered with free flaps. Flap blister occurred in 13 cases and vascular crisis in 3 cases. The flaps survived in 40 cases, wound healing by first intention was achieved in 38 cases, and by second intention in 2 cases. The donor skin-grafting was survival. After operation, 30 patients were followed up 8 to 20 months with an average of 10.6 months. The flaps had satisfactory appearance and soft texture, and the finger tip had no touch pain. The sensory function of the flaps was restored at 4-6 weeks after operation; two-point discrimination was 6.0 to 10.0 mm in 24 flaps at 12-15 months. According to the total active movement (TAM) evaluation system introduced by the American Society for

    2016-09-01

    Background Reconstruction of high-risk fascia, tendon, or ligament defects may benefit from vascularized tissue. The iliotibial band (ITB), a thick fibrous tract of connective tissue, serves as a potential donor site for free tissue transfer but its blood supply has not been thoroughly investigated. The aim of this anatomical study was to investigate the vascular supply to the distal ITB and its role as a free fascial flap. Methods We dissected 16 fresh-frozen cadaveric legs and injected latex into the superolateral geniculate artery (SLGA). A distal ITB fascial flap was designed and measurements were taken for flap dimensions, pedicle length and size, and SLGA perfusion territory. Results The SLGA perfused 11.5 ± 2.3 cm of distal ITB (proximal to the lateral femoral epicondyle) and provided 6.4 ± 0.7cm of pedicle length to the ITB flap. Conclusions Chimeric options to include bone (from the lateral femoral condyle), cartilage (from the lateral femoral trochlea), muscle (from vastus lateralis or biceps femoris), and skin are possible. Surgical harvest techniques are proposed, including preservation of ITB insertions to minimize lateral knee instability. Clinical validation is needed to determine the role of the distal ITB free fascial flap in reconstructive microsurgery.

    2011-01-01

    To evaluate the role of creating an alar-based advancement flap in narrowing the nasal base and correcting excessive alar flare. Case series with chart review. This is a retrospective record review study. The study included 35 cases presenting with a wide nasal base and excessive alar flaring. The surgical procedure combined the alar base reduction with alar flare excision by creating a single laterally based alar flap. Any caudal septal deformities and any nasal tip modification procedures were corrected before the nasal base narrowing. The mean follow-up period was 23 months. The mean alar flap narrowing was 6.3 mm, whereas the mean width of sill narrowing was 2.9 mm. This single laterally based advancement alar flap resulted in a more conservative external resection, thus avoiding alar wedge overresection or blunting of the alar-facial crease. No cases of postoperative bleeding, infection, or keloid were encountered, and the external alar wedge excision healed with no apparent scar that was hidden in the depth of the alar-facial crease. The risk of notching of the alar rim at the sill incision is reduced by adopting a 2-layer closure of the vestibular floor. The alar base advancement flap is an effective technique in narrowing both the nasal base and excessive alar flare. It adopts a single skin excision to correct the 2 deformities while commonly feared complications were avoided.

    Reconstruction of distal thumb injuries still remains a challenge for hand surgeons. Surgical treatment includes the use of local, regional, and free flaps. The purpose of this report is to present the results of the use of a sensitive reverse flow first dorsal metacarpal artery (FDMA) flap. The skin flap was designed on the radial side of the proximal phalanx of the index finger based on the ulnar and radial branch of the FDMA and a sensory branch of the superficial radial nerve. This neurovascular flap was used in five patients to cover distal soft-tissue thumb defects. All flaps achieved primary healing except for one patient in whom superficial partial necrosis of the flap occurred, and the defect healed by second intention. All patients maintained the thumb original length and were able to return to their previous daily activities. The reverse flow FDMA flap is a reliable option to cover immediate and delayed defects of distal thumb, offering acceptable functional and cosmetic outcomes in respect to sensibility, durability, and skin-match.

    2016-01-01

    Full Text Available Context: The most common malignant tumours of the face are basal cell carcinoma, squamous cell carcinoma and melanoma. While the results of skin graft are less than satisfactory for large areas to cover, distant flaps are bulky with a poor colour match. Local fasciocutaneous flaps provide reasonable option for reconstruction of facial defects with good colour and texture match and good success rate. Aims: This study aimed to analyse the various modalities of reconstruction after resection of facial malignancies and their advantages and disadvantages. Settings and Design: This was a retrospective study. Materials and Methods: Of 70 patients, 34 were managed with V-Y advancement flap, 24 with nasolabial flap, 8 with median forehead flap and 4 with standard forehead flap cover. The duration of follow-up ranged from 6 months to 2 years. Statistical Analysis Used: Nil. Results: Of 34 V-Y advancement flaps, 2 showed suture dehiscence at the apex of triangle which was allowed to heal secondarily with regular dressings. All the 24 nasolabial flaps were healthy without any complication. All patients had satisfactory functional and cosmetic outcomes. Conclusions: In our experience, local flaps give the best results and are the first choice for reconstruction of the face. Most defects can be best closed by nasolabial, V-Y advancement and forehead flap. Outstanding functional and cosmetic results can be achieved. Proper execution requires considerable technical skill and experience.

    The principles of perineal reconstructive surgery comprise adequate filling of the defect along with stable and durable skin coverage, with a low morbidity rate. Two-flap perineal reconstruction is a simple, fast and reliable technique that uses a single donor site. This improves scar position with low morbidity. It is based in the use of 2flaps; one flap fills the defect with a «turn over» technique and the other is a rotation - advancement flap for skin coverage. A 52-year-old male diagnosed with Lynch syndrome who underwent laparoscopic abdominoperineal amputation for adenocarcinoma of the lower rectum and developed recurrence 2years later over the perineal scar that required radical resection and perineal reconstruction. The use of this approach facilitates perineal reconstruction and enables treatment of patients with large and complex defects in frequently irradiated tissues where wound dehiscence and infection are common.

    Full Text Available OBJETIVO: Estabelecer relação entre a sobrevivência de retalhos cutâneos em ilha submetidos à isquemia prolongada e o uso da estreptoquinase e do alopurinol administrados após o período de isquemia prolongado. MÉTODOS: Foram utilizados 48 ratos machos da raça Wistar, com peso entre 300 e 350g, divididos em quatro grupos com 12 cada um, sendo; grupo controle, alopurinol, estreptoquinase e associação de alopurinol com estreptoquinase, submetidos à dissecção de retalho epigástrico em ilha, seguido de clampeamento do feixe vascular, por oito horas em isquemia mista normotérmica. Após este período, as pinças foram retiradas e cada animal recebeu o esquema terapêutico proposto através de injeção intravenosa. A análise da sobrevivência dos retalhos foi realizada no sétimo dia de pós-operatório. Foram realizadas análises descritivas (% de área necrótica e de variâncias, bem como comparações múltiplas de Dunnett T3 entre os quatro grupos e o teste da mediana. RESULTADOS: O grupo controle apresentou em média 79,88% de necrose da área total. Aqueles que receberam alopurinol apresentaram em média 64,05% de necrose e o grupo que recebeu estreptoquinase apresentou em média 55,52% de necrose. Com a associação das duas drogas, os ratos apresentaram 54,30% em média de necrose do retalho. Aplicando o teste Dunnett e o teste da mediana verificou-se de que o grupo estreptoquinase é o com menor percentual de necrose neste estudo. CONCLUSÃO: A administração sistêmica da estreptoquinase após oito horas de isquemia mista normotérmica resultou em aumento da sobrevivência de retalhos epigástricos em ilha em ratos, quando comparada à administração de alopurinol, associação do alopurinol e estreptoquinase e do grupo controle.BACKGROUND: To establish a relation between the survival rate of island skin flaps submitted to prolonged ischemia and the effect of streptokinase and allopurinol administered after the ischemic

    Full Text Available Flap surgery is treatment for periodontal disease with alveolar bone destruction. Surgical periodontal flap with conventional incision will result in gingival recession and loss of interdental papillae after treatment. Dilemma arises in areas required high aesthetic value or regions with a fixed denture. It is challenging to perform periodontal flap with good aesthetic results and minimal gingival recession. This case report aimed to inform and to explain the work procedures, clinical and radiographic outcomes of surgical papilla preservation flap in the area that requires aesthetic. Case 1 was a surgical incision flap with preservation of papillae on the anterior region of teeth 11 and 12, with a full veneer crown on tooth 12. Case 2 was a surgical incision flap with preservation of papillae on the posterior region of tooth 46 with inlay restoration. Evaluation for both cases were obtained by incision papilla preservation of primary closure was perfect, good aesthetic results, minimal gingival recession and the interdental papillae can be maintained properly. In conclusion, periodontal flap surgery on the anterior region or regions that require high aesthetic value could be addressed with papilla preservation incision. Incision papilla preservation should be the primary consideration in periodontal flap surgery if possible.DOI: 10.14693/jdi.v19i3.144

    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.

    Lateral internal sphincterotomy (LIS) is considered the surgical treatment of choice for chronic anal fissure (CAF). Flap techniques for fissure coverage have the advantage of primary wound healing, potentially providing better functional results and faster pain relief. The standard surgical strategy for CAF consisting of conventional LIS (CLIS) up to the dentate line was modified by "tailoring" the LIS to the apex of the CAF, but never greater than 1 cm, and by advancing a dermal flap for coverage of the CAF (LIS + flap) after fissurectomy. Thirty consecutive patients who underwent "LIS + flap" were compared with 32 patients who had been previously treated by CLIS. A modified, trapezoid-like Y-V flap from perianal skin was advanced into the CAF base. Pain at the first postoperative day, pain at defecation during the first week, postoperative use of analgesics, and time for patients' pain relief were significantly less at the "LIS + flap" group (P < 0.01). Objective healing was achieved faster (P < 0.01) and soiling episodes were less (P < 0.05) after "LIS + flap." The addition of a dermal flap after "conservative" LIS resulted in better healing and significantly less postoperative discomfort than the isolated application of CLIS.

    Full Text Available Background:   To introduce our experience of using the free neurovascular flap from great and second toe. Methods:   Thirteen patients (fifteen fingers sought surgical treatment for soft tissue defects of the hand at our medical institutin between March 2006 and September 2009. In two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. In twelve, in the treatment of pulp defect of finger with fibular side flap of great toe or tibial side flap of second toe. In one, in the treatment of defect of distal middle with composite flap with distal digital bone of second toe. Results:   All flaps were survived. The average subjective satisfaction score was 8.08 (range 4-10. Nine patients (69% experienced cold intolerance, and 2 patients (15% dysesthesia. The Semmes-Weinstein sensitivity score was between 3.47and 4.72 on the flap, and 0-4.18 on the donor site. The mean two-point discrimination was 6.8 mm (range 4-12. Grip strength was 10% less than in the unaffected hand. The proximal interphalangeal mobility loss was less than 15 degrees. Conclusions:   Our results indicated that these free flaps from toe are useful for patients with a small soft-tissue defect in hand.

    In secondary autologous breast reconstruction, the current standard is a flap derived from the lower abdomen or the back. If these donor sites are not available because of lack of tissue, prior operations, or simply the patient's desire to avoid these donor sites, the authors use the transverse musculocutaneous gracilis flap if feasible. The authors retrospectively evaluated only patients where secondary autologous breast reconstruction was performed with a transverse musculocutaneous gracilis flap because of the prior mentioned reasons. Indications, limitations, advantages, and technique are discussed by sharing the authors' experience in 23 patients using 26 transverse musculocutaneous gracilis flaps. No flap loss could be observed in this series. In four patients, minimal lateral skin necrosis could easily be managed by débridement and primary wound closure. In 12 cases, subsequent lipofilling was performed for a better breast shape. On average, patient satisfaction was high. Secondary reconstruction after simple mastectomy using the transverse musculocutaneous gracilis flap requires a little more experience than after skin-sparing mastectomy but, especially combined with later lipofilling, can lead to an optimally shaped breast in selected patients with substantial skin laxity and fat distribution at the inner thigh.

    Treacher Collins syndrome (TCS) is a rare genetic disorder leading to congenital craniofacial malformations. Although this syndrome presents with various symptoms, corrective surgery for bilateral microtia with low hairline is one of the most challenging operations given the complex contours of the external ear. In this technical note, a novel, simple procedure for dealing with the low hairline by using a hinged mastoid fascial flap simultaneously with costal cartilage grafting is described. Several techniques for the reconstruction of low hairline microtia have been reported previously, such as skin graft, skin flap, and tissue expander, but the high number of repeat operations and residual scars remain problematic. As a simultaneous procedure with framework grafting, the use of a temporoparietal flap with skin grafting is popular; however, its drawbacks include the operative scar, decreased hair growth, and hair thinning. Patients with TCS show anatomical variations of the superficial temporal vessels supplying the temporoparietal flap. In contrast, due to the high vascularity of the mastoid fascia, the mastoid fascial flap can be elevated safely and easily as an anteriorly, posteriorly, superiorly, or inferiorly based flap.

    Background For large tongue defects, reconstructive surgeons have devised a variety of feasible options, such as radial forearm free flap and anterolateral thigh (ALT) flap. In our institution, peroneal flap has been the workhorse flap for the soft tissue defect in head and neck reconstruction. We present our experience using peroneal flap in tongue reconstruction. Patients and Methods The study included 47 patients who had undergone tongue reconstructions with peroneal flaps after tumor resection. The size and location of the defect after tumor resection determined whether the peroneal flaps could be harvested as pure septocutaneous flaps to solely reconstruct the neotongue or to carry an additional muscle bulk to fill the adjacent defect. Retrospective chart review was used to look for postoperative complications and to perform functional assessments (which were also performed through telephone inquiry). Results Of the 47 patients, 3 (6%) had flap failure and 1 (2.1%) had partial flap necrosis. The hemiglossectomy group had better results than the total glossectomy group with respect to speech and diet, but neither of these results reached statistical significance (p = 1.0 for speech and p = 0.06 for diet). The results of the subtotal glossectomy group were better than those of the total glossectomy group with respect to diet (p = 0.03). No statistically significant differences were noted among the three groups with respect to cosmetic aspect (p = 0.64). Conclusions Considering its reasonable postoperative complication rates and functional results, peroneal flap ca
