Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision. All patients received silicone intubation to the lacrimal system. Surgical outcome was measured in terms of patient-reported epiphora as follows: 1) complete resolution, 2) improvement >50%, 3) improvement 50% improvement. There were 4 patients (7%) who had <50% improvement. There was 1 (2%) intraoperative complication and 2 (4%) postoperative complications recorded. Piezourgery is a viable modality for performing external DCRs. The lack of surgical complications shows a potential for decreased soft tissues damage. The surgical success rate based on patient-reported epiphora is similar to those published for mechanical external DCRs. This modality may benefit the novice surgeon in the reduction of soft and mucosal tissue damage.

Methods: Patients with nasolacrimal obstruction and chronic dacryocystitis who were scheduled for an endonasal DCR underwent tear meniscus examinations before and 2 months after surgery. Vertical scans of the inferior menisci were performed before and at 1, 3, 5, 7, and 10 minutes after the instillation of rebamipide ophthalmic suspension. The tear menisci areas were measured with imaging software. Ten young adults without epiphora formed the control group.Results: Anatomical success was achieved on 22 sides of 21 patients. The patients’ postoperative tear menisci were significantly smaller than the preoperative menisci at all points during the test, and the response to volume loading in the postoperative patients was corrected to nearly that of the young, healthy adults. Nevertheless, the postoperative meniscus area tended to be larger than that of the young adults at all points.Conclusion: The reduced tear meniscus area after DCR reflected the success of the surgical procedure. However, incomplete recovery of the meniscus after the test might suggest a residual disorder of the lacrimal drainage system after DCR.

To evaluate the success rate and complications of intraoperative Mitomycin-C in dacryocystorhinostomy surgery. This study included total 90 eyes of 90 patients fulfilling the inclusion criteria.The surgical procedure of external DCR done with intraoperative Mitomycin-C with a neurosurgical cottonoid soaked with 0.2mg/ml. Mitomycin C was applied to the anastomosed flaps and osteotomy site for 10 minutes, without Silicon tube intubation. Surgery was done under local as well as general anesthesia. Patients were followed for 6 months. Out of 90 patients included in this study, only 2 patients complained of persistent epiphora after 6 months follow-up and were labeled as failed DCR. Remaining 88 had either no tearing or significant improvement of tearing after 6 months follow up and patent lacrimal system by syringing without pressure. Success rate in this procedure was 97.77% (p-value< 0.001). This study showed very high rate of success. Only complication noted was excessive nasal bleeding which was easily controlled. Intraoperative Mitomycin-C application in external DCR is safe, effective, cheap adjunct that helps to achieve good results of DCR surgery. (author)

Full Text Available Abstract Background To evaluate the clinical outcome of primary endonasal laser assisted dacryocystorhinostomy (ENL-DCR using the potassium-titanyl-phosphate laser. Methods We retrospectively reviewed all primary ENL-DCRs performed within a period of twelve months by the same combined Ophthalmology and Otorhinolaringology team in Freeman Hospital, Newcastle upon Tyne, UK. The main outcome measure for success was resolution or significant improvement of epiphora. Details of surgery, intraoperative and postoperative complications, as well as pathology associated with failure were also studied. Patients were followed up for at least 12 months. Results A total of 41 consecutive ENL-DCRs on 29 patients (22 females, 7 males, mean age 75 years were analysed. All patients had bicanalicular silicone intubation for at least 4 months. The success rate at 12 months postoperatively was 78.1%. Pathology associated with failure included: intranasal pathology (12.2%, mucocele (7.3%, and systemic sarcoidosis (2.4%. No significant intra-operative complications were recorded. Conclusion The ENL-DCR with potassium-titanyl-phosphate laser can be considered as a safe and efficient primary procedure for the treatment of nasolacrimal duct obstruction.

Endonasal dacryocystorhinostomy (DCR) has been established as a standard procedure of lacrimal surgery, since it causes much less tissue damage than ab externo procedures. Diffiulties in visualization of the target area has been a limitation to the transnasal approach. An improvement of the classical endonasal DCR was achieved by the introduction of a transcanalicular endoillumination (TCE) of the lacrimal sac using a 23-Gauge vitreoretinal light probe, which can easily be intubated into the cannaliculi and advanced into the the lacrimal sac. Illumination of the lacrimal sac guides the endonasal approach and facilitates the creation of a lacrimal bypass. In our standard procedure a bicanalicular silicone intubation through the osteotomy is finally placed. Due to the introduction of TCE of the lacrimal sac, the surgical procedure of endonasal DCR became less traumatic and needed a significantly reduced operating time.

Objective: To assess the long-term functional outcome of external dacryocystorhinostomy (DCR) in terms of epiphora. Study Design: Single-group cohort study. Place and Duration of Study: Section of Ophthalmology, The Aga Khan University Hospital, Karachi, from January 2000 to June 2010. Methodology: This study included adults who underwent external DCR surgery at the AKUH during January 2000 to June 2010. The main outcome measure was the proportion of patients reporting to have developed epiphora after surgery. During the telephonic interviews participants were asked if they had a recurrence (symptoms such as watering or discharge) after surgery. Individuals answering in affirmative were asked when the symptoms started. Data on age at surgery, gender and pre-operative symptoms were collected from medical records. Recurrence-free curves were calculated according to the Kaplan-Meier method. Results: A total of 44 persons who underwent DCR surgery were contactable by telephone in 2011 and all agreed to participate in the study. The mean age of the patients at the time of surgery was 48.0 A+- 15.8 years. Overall, 38.6% (17/44) participants reported having developed epiphora after surgery. The overall median recurrence-free time was 1.7 years; there was no statistically significant difference in the median recurrence-free time between men and women. Conclusion: The long-term functional outcome of external DCR surgery does not appear to be optimal and, in fact, far worse than the short-term results reported in the international literature.

Full Text Available Hatem A Tawfik,1 Osama R Youssef21Department of Ophthalmology, 2Department of Anesthesiology, Ain Shams University, Cairo, EgyptBackground: The purpose of this paper is to describe a simplified local anesthesia technique for external dacryocystorhinostomy (EXT-DCR.Methods: In this pilot, retrospective, noncomparative, interventional case series, 448 patients (480 eyes underwent EXT-DCR using a simplified local anesthesia technique. Nasal mucosal anesthesia was achieved using combined application of 6 mL of oxymetazoline 0.025% nasal spray and lidocaine 1% in the same spray bottle, without any packing of the nose with either pledgets or ribbon gauze. Local infiltration anesthesia consisted of subcutaneous injection of a 7 mL mixture of 2% lidocaine with 1:100,000 epinephrine injected on the flat side of the nose beneath the incision site, in addition to a second medial peribulbar injection (3 mL, 2% lidocaine without epinephrine.Results: Successful unilateral or bilateral EXT-DCR was achieved in 432/448 patients (96.4%. Four patients could not tolerate the procedure under local anesthesia and were converted to general anesthesia. Four patients required additional local anesthetic injections because of intolerable pain. Heavy sedation was essential in eight uncooperative patients because surgical manipulation was impossible. The remaining patients tolerated the procedure well. The intraoperative bleeding rate was very low except in one patient. Mean operative time was 16 minutes. Severe postoperative epistaxis was observed in four patients. Temporary anosmia developed in one patient.Conclusion: Our simplified local anesthesia approach of EXT-DCR is convenient for the patient because it avoids unnecessary nasal packing. It is also safe and effective, as evidenced by the high rate of successful completion of the procedure without conversion to general anesthesia or the need for supplemental local anesthesia.Keywords: local anesthesia, external

In this study, we compared the advantages and disadvantages of piezosurgery and hammer-chisel used in endoscopic dacryocystorhinostomy (EDCR). Between January 2012 and January 2016, 10 women and 8 men in whom piezosurgery was used (group 1) and 11 women and 7 men in whom hammer-chisel was used (group 2) during EDCR operations were compared retrospectively. Recurrence, operation time, postoperative bleeding, and operative cost were evaluated in patients who were followed for an average of 11.8 months. In addition, visual analogue scale (VAS) was used to assess pain at 6 hours postoperatively. No recurrence was observed in group 1, but recurrence was observed in 2 patients in group 2 (P = 0.685). There was no postoperative bleeding in both groups. The mean duration of operation was 30.6 ± 8.2 minutes in group 1 and 46.8 ± 9.5 minutes in group 2 (P = 0.038). The VAS score in group 1 was 2.7 ± 1.4 and the VAS score in group 2 was 5.8 ± 2.2 (P = 0.01). Piezosurgery costs an additional $325 for each patient while the use of the hammer-chisel does not incur additional costs. Piezosurgery causes shorter operation time, less recurrence, and less pain when compared with hammer-chisel.

Study Design. Questionnaire to determine subjective success of Endo-DCR. Methods. From May 2013 to August 2014, a total of 95 eyes with epiphora presented to the Myoung Eye Plastic Surgery Clinic in Seoul, Korea, and were treated with Endo-DCR under LAS. Three nerve blocks were administered to achieve local anesthesia. Postoperatively, the wound site was packed with Nasopore to control bleeding and promote wound healing. Outcome measures included a patient questionnaire completed on postoperative day 7 to evaluate intraoperative and postoperative pain based on the VAS (0 to 10. Results. Mean intraoperative and postoperative pain scores were 1.03 and 1.64, respectively, for 95 eyes. Of the 95 eyes treated, the patients in 82 eyes (86.31% reported that they would prefer LAS over GA for a repeat Endo-DCR. The subjective and objective surgical success rates were 90.14% and 95.77%, respectively. Conclusions. Endo-DCR carried out under LAS with the patient in the leaning position is more useful, efficient, and feasible than Endo-DCR performed under GA with the patient in the supine position.

Background The aim of this study was to assess the etiological factors contributing to the failure of a dacryocystorhinostomy (DCR). Patients and methods Retrospective review was performed in 100 consecutive patients who were diagnosed with anatomically failed DCR at presentation to a tertiary care hospital over a 5-year period from 2010 to 2015. Patient records were reviewed for demographic data, type of past surgery, preoperative endoscopic findings, previous use of adjuvants such as intubation and mitomycin C, and intraoperative notes during the re-revision. The potential etiological factors for failure were noted. Results Of the 100 patients with failed DCRs, the primary surgery was an external DCR in 73 and endoscopic DCR in 27 patients. Six patients in each group had multiple revisions. The mean ages at presentation in the external and endoscopic groups were 39.41 years and 37.19 years, respectively. All patients presented with epiphora. The most common causes of failure were inadequate osteotomy (69.8% in the external group and 85.1% in the endoscopic group, P=0.19) followed by inadequate or inappropriate sac marsupialization (60.2% in the external group and 77.7% in the endoscopic group, P=0.16) and cicatricial closure of the ostium (50.6% in the external group and 55.5% in the endoscopic group, P=0.83). The least common causes such as ostium granulomas and paradoxical middle turbinate (1.37%, n=1) were noted in the external group only. Conclusion Inadequate osteotomy, incomplete sac marsupialization, and cicatricial closure of the ostium were the most common causes of failure and did not significantly differ in the external and endoscopic groups. Meticulous evaluation to identify causative factors for failure and addressing them are crucial for subsequent successful outcomes. PMID:27555748

Mitomycin-C in dacryocystorhinostomy: From experimentation to implementation and the road ahead: A review

Full Text Available Dacryocystorhinostomy (DCR is the procedure of choice in patients with epiphora due to primary acquired nasolacrimal duct obstruction. The evolution of surgical tools, fiber-optic endoscopes, effective anesthesia techniques, and the adjunct use of antimetabolites intraoperatively; namely mitomycin-C (MMC have significantly contributed to the advancement of DCR surgery. MMC is a systemic chemotherapeutic agent derived from Streptomyces caespitosus that inhibits the synthesis of DNA, cellular RNA, and protein by inhibiting the synthesis of collagen by fibroblasts. Even the cellular changes in the human nasal mucosal fibroblasts induced by MMC at an ultrastructural level have been documented. There, however, seems to be a lack of consensus regarding MMC: The dosage, the route of delivery/application, the time of exposure and subsequently what role each of these variables plays in the final outcome of the surgery. In this review, an attempt is made to objectively examine all the evidence regarding the role of MMC in DCR. MMC appears to improve the success rate of DCR.

The disease has a predilection for the upper and lower respiratory tracts (lungs, nose, sinus, and kidneys. WG may be systemic, severe, and potentially lethal, but it may also be limited to the otolaryngological area or to the eyes and the orbits. Obstruction of the lacrimal pathway is a possible complication of the disease that affects approximately 7% of patients with WG. It usually occurs as a direct extension of sinonasal disease and typically is a late manifestation. Management of such a condition is generally viewed as difficult. We report the case of a patient with a quiescent WG limited to the otolaryngological area. This patient presented a bilateral obstruction of the nasolacrimal ducts caused by bilateral extensive adhesions in the nasal cavity. Because she had several episodes of left-side acute dacryocystitis which necessitated several courses of broad-spectrum antibiotics, she successfully underwent an endonasal endoscopic dacryocystorhinostomy using a diode laser and powered instrumentation. The authors describe the clinical case, the surgical technique, and review the literature.Keywords: Wegener’s granulomatosis, recurrent dacryocystitis, endonasal DCR, diode, laser, powered instrumentation

To evaluate differences in the surgical outcomes of endoscopic dacryocystorhinostomy (DCR) according to four different surgical methods. This retrospective study included 222 patients who underwent endoscopic DCR from 2011 to 2013. All patients were assigned to one of four groups according to instruments for incision of nasal mucosa and the formation of mucosal flap: group 1, a sickle knife with mucosal flap; group 2, a sickle knife without mucosal flap; group 3, electrocautery with mucosal flap; and group 4, electrocautery without mucosal flap. The follow up period was at least 6 months. There were 33 eyes in group 1, 44 eyes in group 2, 49 eyes in group 3, and 97 eyes in group 4. There were no significant differences in success rate between groups (P = 0.878). Wound healing time was significantly different between groups (P knife may be more helpful and effective for shortening wound healing time rather than making mucosal flaps in endoscopic DCR.

METHODS: A total of 31 patients(32 eyespresenting with acute dacryocystitis were treated with EN-DCR combined with stent implantation under antibiotic cover from April 2014 to December 2015. These patients were followed up for 3 to 12mo. RESULTS: The medial canthal edema and erythema was gradually reducing within 48h in all patients. The hospitalization time took 2 to 8d(average 3.8±1.6d. Patients underwent removal of stent about 3mo after surgery. Thirty-one eyes showed no symptoms such as lacrimation or pus discharging, and irrigation of lacrimal duct was unobstructed. Irrigation of lacrimal duct was passable in 1 of 32 patients who has a relative narrow ostial. Results in this series, 31 cases were cured,1case improved, the total cure rate was 97%. CONCLUSION: There is no evidence shown that EN-DCR combined with stent implantation can increase the risk of spreading infection through tissue planes, causing septicemia, and exacerbating inflammation. Instead, it has advantages like gradual reduction in inflammatory symptoms, economic benefits of reduced patient stay, maintenance of the orbicularis muscle lacrimal pump and absence of external scar. It is indicated that EN-DCR combined with stent implantation is a safe and feasible surgical procedure for patients with acute dacryocystitis.

The purpose of this study was to evaluate the effectiveness of endocanalicular diode laser dacryocystorhinostomy (DCR), which is a minimally invasive surgical technique, in pediatric patients with congenital nasolacrimal duct obstruction (NLDO). A retrospective study was carried out on patients treated between October 2008 and August 2009 for nasolacrimal duct obstruction with an endocanalicular diode laser procedure. Patients diagnosed as having nasolacrimal duct obstruction were included in this study and an endocanalicular diode laser procedure was performed. The main outcome measures were patients' previous treatments, clinical presentation, operative and postoperative complications, postoperative follow-up and resolution of epiphora. Eighteen children (10 girls, 8 boys) with a mean age of 6.11 ± 2.08 years (range, 4-10) underwent 20 endocanalicular laser DCR operations for congenital NLDO. In all eyes (100%), there was a history of epiphora and chronic dacryocystitis; two (10%) presented with acute dacryocystitis. Previous procedures included probing and irrigation of all eyes (100%) and silicone tube intubation in nine eyes (45%). None of the patients underwent any previous DCR operations. During a mean postoperative follow-up period of 20.50 ± 3.24 months (range, 14-24 months), the anatomical success rate (patency of ostium on nasal endoscopy) was 100%, and the clinical success rate (resolution of epiphora) was 85%. Endocanalicular diode laser DCR is an effective treatment modality for pediatric patients with congenital NLDO that compares favorably with the reported success rates of external and endoscopic endonasal DCR. Moreover, it has an added advantage of shorter operative time, less morbidity and avoidance of overnight admission.

Full Text Available Purpose. The aim of this study is to propose a simple and efficient combination surgery for the management of dacryocystitis with canalicular obstruction. Methods. A retrospective noncomparative case series of dacryocystitis with canalicular obstruction has been studied. Twelve patients with dacryocystitis and canalicular obstruction underwent a conventional endoscopic endonasal dacryocystorhinostomy (EE-DCR combined with a modified canalicular repair. Postoperative observations included slit lamp, fluorescein dye disappearance test, lacrimal syringing, lacrimal endoscopy, and nasal endoscopy. Results. After 6–18 months of postoperative follow-up, the symptoms of epiphora and mucopurulent discharge disappeared completely in 10 patients, and occasional or intermittent epiphora remained in 2 patients. All of the twelve patients showed an opened intranasal ostium and normal fluorescein dye disappearance test. Patent bicanalicular irrigation was achieved in 9 patients. One patient had a partial and the other two had a complete reobstruction by lacrimal irrigation to their repaired lower canaliculus; however, all of them had a patent lacrimal irrigation to upper canaliculus. The functional success rate for the combination surgery is 83% (10/12, and anatomical success rate is 75% (9/12. Conclusion. EE-DCR combined with modified canalicular repair is a simple and efficient method for the management of dacryocystitis with canalicular obstruction.

The aim of the study is to compare the subjective (relief of symptoms) and objective (endoscopic visualization of ostium patency at the time of syringing) outcomes at the end of two procedures-Endonasal DCR versus External DCR with Mitomycin C and to assess the role of Mitomycin C in maintaining patency of nasolacrimal drainage system. Prospective randomized comparative study was performed. Thirty-five patients were enrolled in each endoscopic and external dacryocystorhinostomy groups with Mitomycin C (MMC) application. The 37 eyes underwent endonasal DCR (28 unilateral primary eyes + 1 bilateral primary eyes + 5 unilateral revision eyes + 1 bilateral revision eye) while 35 eyes underwent external DCR (34 unilateral primary eyes + 1 unilateral revision eye). Mitomycin C 0.2 mg/ml was applied intra-operatively for 5 min to the ostium site at the end of endonasal or external DCR procedure. Objective assessment by syringing at the end of 1 year in the endonasal group showed 35 eyes (94%) were patent, 1 (3%) was partially blocked and 1(3%) was completely blocked; while in external group all 35 eyes (100%) were patent. Endoscopic visualization of the ostium at the time of syringing showed only one eye (3%) in the endonasal group was blocked while all the other eyes in both groups were patent. Both groups had a mean follow-up of 6-36 months. No complications were associated with use of Mitomycin C. In conclusion, intra-operative use of Mitomycin C in both endoscopic DCR and external DCR is safe and effective in increasing the success rate.

External dacryocystorhinostomy (DCR) is the method of choice to treat nasolacrimal duct (NLD) obstruction and the other approaches are compared with it, with a failure rate of 4% to 13%. The current study aimed to assess the causes of failure in external DCR by postoperative endoscopic and pathological evaluation. The current retrospective cross sectional study followed-up113 patients with external DCR and silicone intubation for three months. Silicone tubes were removed after the third months. Failure was confirmed based on the clinical findings and irrigation test. Paranasal sinus computed tomography (CT) scanning, and endoscopic and pathological evaluations were performed in the failed cases. Totally, 113 patients underwent external DCR. The patients included 71 females and 42 males. The mean age of the patients was 55.91 years; ranged from 18 to 86. Epiphora was the most common complaint before surgery (90.3%). Clinically, epiphora continued in 17 cases (15%), of which 94.11% had at least one sinus CT abnormality and 82.35% had at least one endoscopic abnormality. The most common endoscopic findings were deviated septum (70.6%), scar tissue (52.94%), concha bullosa (46.9%), septal adhesion (47.05%), enlarged middle turbinate (41.2%), and sump syndrome (11.7%). The failure was significantly associated with the chronicity of the initial symptoms (P-value=0.00). Pathologically, there were significant relationship amongst the failure rate, scar formation, and allergic rhinitis (P-values =0.00 and <0.05, respectively). Preoperative endonasal evaluation and consultation with an otolaryngologist can improve surgical outcomes and help to have a better conscious to intranasal abnormalities before external DCR surgery.

Failure of primary dacryocystorhinostomy (DCR) often requires revision surgery to inspect the cause of failure and re-establish anatomic patency. This study aims to specifcally compare the anatomical causes of failure noted during revision DCR of primary external DCR (EX-DCR) and compare the difference between consultants and fellows. A retrospective review of 37 patients who underwent revision of a primary external approach DCR over a 7-year-period in a University Hospital. All primary surgery was performed by either a consultant surgeon or senior oculoplastic fellow. Details of the initial pathology prior to primary DCR and grade of operating surgeon were collected along with perioperative surgical findings. The cause of failure of the initial surgery was classified according to perioperative findings. Failure was classified as either inappropriately sized/located ostium or fibrous/membranous soft tissue obstruction of the newly created ostium. The cause of failure of the initial surgery was soft tissue obstruction in 43.3% and an inappropriately sized/located ostium in 56.7%. In those patients whose primary surgery was performed by a consultant, 73.3% were found to have a soft tissue obstruction and 26.7% were found to have an inappropriately sized/ located ostium. In contrast, if initial surgery was performed by a fellow, 22.7% were found to have a soft tissue obstruction and 77.3% an inappropriately sized/ located ostium (p =0.002). Where the primary surgeon has been a trainee there is a trend toward inadequately sized or located ostium being the most likely causative factor in failure of primary EX-DCR.  Hippokratia 2015; 19 (3): 216-218.

To assess the subjective success and quality of life of adult patients post endoscopic endonasal dacryocystorhinostomy (EE-DCR) for acquired nasolacrimal duct obstruction. Retrospective, questionnaire study performed at least 6 months post EE-DCR. Hundred and ten of the 282 consecutive patients who underwent EE-DCR. A standardised questionnaire (Glasgow Benefit Inventory, GBI) was used to analyse the quality of life. The questionnaire examines four parameters, providing total, subscale, social, and physical scores. We aimed to assess patient experience following EE-DCR surgery. Total GBI scores range from -100 to +100, the former reflecting maximal negative benefit and corresponding to subjective worsening of tearing and impact on quality of life. Any positive score reflects a satisfactory surgical outcome and +100 represents maximal positive benefit. A score of zero is no perceived benefit. The average age was 62 years, 63% were female. In three of the parameters measured, there was a subjective improvement post surgery: subscale score 22.16 (95% CI: 15.23-29.09), total score 15.04 (95% CI: 9.74-20.35), and social support score 4.67 (95% CI: 0.93-8.42). Physical health scored -4.47 (95% CI: -10.25 to 1.32). Secondary analyses demonstrate no statistical significance with respect to outcome whether a trainee or consultant performed the procedure. Younger patients (under split median of 63.5) had a better total score 19.04 (95% CI: 11.35-27.74) than those older than 63.5 years (11.04, 95% CI: 3.61-18.47). This study shows that EE-DCR gave patients improvement in quality of life, proven by a validated questionnaire. The mean total score of 15.04 found in our study compares with the 18.7 recorded by Feretis et al in 2009. Results were irrespective of the grade of surgeon, similar to the findings of Fayers et al for functional successes. This study supports the use of EE-DCR for the improvement of quality of life in adult patients.

To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocystorhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3±3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 ± 9.3 months. After a mean follow-up of 14.9±7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.

To evaluate the efficacy of adjunctive mitomycin C (MMC) in transcanalicular multidiode laser dacryocystorhinostomy (TCL-DCR) in different age groups. Ninety-six eyes of 96 patients who underwent TCL-DCR for the treatment of nasolacrimal duct obstruction were included in this retrospective, comparative study. Patients were divided into 4 groups based on age and intraoperative use of MMC: group 1, TCL-DCR without MMC in the 20- to 44-year age group; group 2, TCL-DCR with MMC in the 20- to 44-year age group; group 3, TCL-DCR without MMC in the 45- to 76-year age group; group 4, TCL-DCR with MMC in the 45- to 76-year age group. The postoperative evaluation consisted of calculating and comparing the success rates between groups. Success rates at the final visit were 50% for group 1, 66.66% for group 2, 79.16% for group 3, and 84.61% for group 4. The differences between group 1 and group 4, and group 1 and group 3, were significant (p = 0.01 and p = 0.038, respectively). Logistic regression showed that age group had significant effect on success rate (p = 0.013). However, use of MMC had no significant effect on success rate (p = 0.23). The success rates of the TCL-DCR with MMC application were found to be higher than those of TCL-DCR without MMC in different age groups. However, the differences did not reach statistical significance. In addition, our study demonstrated that age may be a significant factor influencing the surgical outcome of TCL-DCR.

Medical records were screened, and photographs and videos were assessed to note the details of various ostial parameters. The major time points in evaluation were 4 weeks, 6 weeks, 3 months, and 6 months post-DCR. The ostia were defined and parameters like shape, size, location, and evolution of ostium were noted. Evaluation parameters were defined for internal common opening (ICO, ostium stents, and ostium granulomas. Ostium cicatrix and synechiae were graded based on their significance. Surgical success rates were computed and ostium characteristics in failed cases were studied.Results: A total of 125 ostia were evaluated on the aforementioned ostium parameters. Because five ostia showed a complete cicatricial closure with no recognizable features, the remaining 120 ostia were studied. The ostium location was anterior to the axilla of middle turbinate in 85.8% (103/120 of the cases. Moreover, 76.6% (92/120 of the ostia were circular to oval in shape, with a shallow base. The ostium size was >8×5 mm in 78.3% (94/120 of the cases. The ICO was found to be located in the central or paracentral basal area in 75.8% (91/120. The anatomical and functional success rates achieved were 96% and 93.6%, respectively. All the five cases with anatomical failures showed a complete cicatrization and the ICO movements were poor in all the three cases of functional failure.Conclusion: The article attempts to standardize the postoperative

To evaluate the results, complications, effectiveness, and operative results of the endocanalicular laser dacryocystorhinostomy (ECL DCR) in the distal obstructions of the lacrimal drainage system. Sixty eyes of 57 patients who had a diagnosis of distal obstruction of the lacrimal drainage system were evaluated retrospectively in this study. All patients underwent ECL DCR by diode laser between October 2008 and July 2009. Forty-nine patients (86%) were females, 8 patients (14%) were males, and age distribution was between 3 and 84 years old (median, 40 y). The canaliculi were intubated by a silicone tube. The patency of the nasolacrimal system was controlled by lacrimal lavage, loss of epiphora, and endoscopic evaluation of the endonasal rhinostomy site with routine follow-up scheduled at first day and 1-week, 1-month, and 3-month postoperative intervals. After the 60 ECL DCRs, 10 patients underwent revision ECL DCR because of the persistent epiphora. The patency of the nasolacrimal duct or the decrease of the symptoms was assigned as success. There were no symptoms at all in 83.3% of the patients. The ECL DCR in the treatment of the distal obstructions of the lacrimal drainage system was easily tolerated by the patients, cosmetically preferred because there was no incision and scar formation with high success rates, and a minimally invasive alternative technique.

To evaluate and compare the success rate of transcanalicular laser-assisted dacryocystorhinostomy with endonasal augmentation, with and without intubation, in patients suffering from primary acquired nasolacrimal duct obstruction, at 1 year of follow up. A prospective, randomized interventional pilot study was conducted at a tertiary care center, in accordance with the guidelines of Declaration of Helsinki. Sixty eyes of 60 adult patients with primary acquired nasolacrimal duct obstruction were included. The participants were divided randomly into 2 equal groups (A and B-without and with bicanalicular intubation, respectively). An osteotomy was first created using 980 nm diode laser (set at 8W continuous mode) transcanalicularly and then enlarged intranasally using Blakesley's nasal forceps, followed by bicanalicular silicon intubation in group B patients. The tubes were removed at the end of 8 weeks. The ostium size was assessed endoscopically at 8 weeks and again at the end of follow up, at 1 year. A successful outcome was defined in terms of ostium patency at the end of 1 year. The results were analyzed at the end of a follow up of 1 year, using various statistical tests (p < 0.05). The mean age of the patients was 35.3 ± 15.89 years, with 23 male and 37 female patients, the 2 groups having a similar male:female ratio. An overall success rate of 90% was achieved at the end of 1 year with no statistically significant difference between the groups. Postoperative complications like tube displacement and punctal, canalicular injury were more in the intubated group. The average osteotomy size was 8.06 ± 5.4 mm at the end of 1 year. Transcanalicular laser-assisted dacryocysto rhinostomy, with endonasal augmentation, is a scarless, effective, daycare procedure, for treatment of primary acquired nasolacrimal duct obstruction with no additional advantage offered by silicone intubation.

We attempted to compare the cytokine composition of tears between primary acquired nasolacrimal duct (NLD) obstruction and normal controls. We investigated the changes in cytokines in tears after endoscopic endonasal dacryocystorhinostomy (DCR). Eighteen patients underwent endonasal DCR, with seven patients undergoing bilateral DCR, resulting in twenty-five DCRs in total. Eleven contralateral un-operated eyes were used as normal controls. Silicone stents were removed 3 months after surgery. Tear samples were collected from all eyes before surgery, and at 1 month, 2 months, 3 months, and 4 months after surgery. The level of interleukin (IL)-1β, IL-2, IL-6, IL-10, transforming growth factor (TGF)-β2, fibroblast growth factor (FGF)-2, and vascular endothelial growth factor (VEGF) in the tears was measured. The concentrations of IL-2, IL-6, IL-10, VEGF, and FGF-2 were significantly higher in eyes with NLD obstruction than controls before surgery (P=0.006, 0.018, 0.002, 0.048, and 0.039, respectively). Most inflammatory cytokines (IL-1β, IL-2, IL-6, VEGF, and FGF-2) were higher in the tears of the DCR group compared with the controls during the postoperative follow-up, but then rapidly decreased to the level of the controls after removal of the silicone stent. The recurred eyes showed a higher level of TGF-β2 and FGF-2 in tears compared with the eyes that showed good surgical results (Ptear levels of inflammatory cytokines were higher in eyes with NLD obstruction than controls. The changes in cytokine level during the postoperative period showed the importance of cytokine analysis in understanding wound healing after DCR.

Maxillectomy followed by radiotherapy and/or chemotherapy can result in lacrimal blockage and the need for subsequent dacryocystorhinostomy (DCR). Endonasal endoscopic DCR, as opposed to external DCR, allows better accuracy and leaves no scar. To date no report was published regarding the results of endoscopic DCR in these patients. The current study presents a retrospective review of all patients with paranasal and skull base tumors who developed nasolacrimal duct blockage after ablative maxillectomy with or without radiotherapy and/or chemotherapy and underwent endonasal endoscopic DCR between January 2006 and October 2012 in a tertiary reference medical center. According to our results, ten patients underwent 11 subsequent endonasal endoscopic DCR. There were 6 men and 4 women with a median age of 55 years (range, 19-81 years); four suffered from benign tumors and six had malignant tumors. All underwent maxillectomy. Six received high-dose radiotherapy. Time interval between primary ablative surgery and endonasal endoscopic DCR was 18 months (range, 7-118 months). Silicone stents were removed after median period of 11 weeks (range, 1-57 weeks). Nine out of ten patients experienced symptomatic improvement following one endonasal endoscopic DCR. One patient had recurrent epiphora and underwent a successful endonasal endoscopic revision DCR. In conclusion, endonasal endoscopic DCR in patients with paranasal and skull base tumors, who previously underwent maxillectomy, is generally successful and not associated with a high rate of complications or failure. Moreover, our findings may suggest that silicone stents can be removed shortly after the operation with high success rate.

To determine the functional and aesthetic outcomes of periciliary "v-incision" external dacryocystorhinostomy (DCR) and to compare with conventional approach. Charts review of consecutive cases of "v-incision" (VDCR) or conventional DCR performed in a single institute, between January 2007 and March 2014. All procedures were performed or supervised by a single surgeon. Two periciliary incisions were made near the skin-mucosal junction at the upper and lower eyelid margins medial to the punctum joining at the medial canthal angle to form a "v" shape. Subcutaneous dissection was carried out inferomedially to reach the anterior lacrimal crest. DCR was then performed in the usual manner. Functional success was defined as no persistent or recurrent epiphora and patency on irrigation of the lacrimal drainage system at least 6 months post-surgery. A cross-sectional aesthetic survey was conducted by asking the patients to rate their scar appearance satisfaction on a visual analogue scale (VAS). External photographs were graded by two independent, masked physicians using VAS as well as the Stony Brook scar evaluation scale (SBSES). Sixty-one patients with median age of 64 years met the inclusion criteria, with median follow-up duration of 28 months. Thirty-eight eyes underwent VDCR, and 23 had conventional DCR. The functional success rate for VDCR was 83.3, 95 % confidence intervals (95%CI) [lower 0.68, upper 0.92] and for conventional DCR was 73.9 %, 95%CI [lower 0.54, upper 0.87]; without statistically significant difference (p = 0.38). VDCR patients rated higher aesthetic outcome on VAS (mean scores 95.5 ± 16.8 vs 82.9 ± 25.1, p = 0.03). On the SBSES, both observers gave higher aesthetic scores to the VDCR group (observer #1 4.6 ± 1.1 and #2 4.7 ± 1.2, p aesthetic outcomes as reported by surgeons and patients. However, a higher proportion of trainees under supervision performed conventional DCR, and it is uncertain whether the outcomes were

Approximately 5% to 10% of patients continue to experience persistent epiphora following an anatomically successful dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction or stenosis. To investigate the management and success rate of so-called "functional failure" of DCR for nasolacrimal duct obstruction by experienced lacrimal surgeons. Multicenter retrospective case series including 5 Australian and New Zealand centers. Participants included 61 patients (71% women [n = 46]; mean age, 66 years) with functional epiphora after 65 DCRs (69% transnasal) who were recruited over a mean of 7.6 years. Inclusion criteria included confirmed preoperative diagnosis of nasolacrimal duct obstruction or stenosis, age greater than 18 years, recurrent or persistent epiphora after DCR, an anatomically successful DCR, and follow-up longer than 6 months. Exclusion criteria included evidence of lacrimal hypersecretion, eyelid malposition, and punctal or canalicular abnormalities. The number, type, timing, and success of all clinical interventions performed for the management of functional epiphora after DCR. Epiphora recurred a mean of 8.9 months after primary DCR; 89% of the cases (n = 58) had evidence of a patent ostium and 100% were patent on lacrimal irrigation. Intubation with a lacrimal stent was performed in 82% of the cases at the time of surgery, and all stents were removed a mean of 8 weeks postoperatively. Epiphora was reported immediately following DCR in 32% (n = 21) of the cases and within 6 weeks after removal of the stent in 31% (n = 20); late recurrence (>12 months after DCR) developed in 37% (n = 24) of the cases. In a total of 15% of the cases, participants declined any treatment following DCR. The remainder underwent a mean of 1.3 interventions (range, 1-3) during a mean of 23 to 41 months after primary DCR, following which 72% (n = 47) of the cases had a successful outcome; 12% (n = 8) failed to achieve improvement, and the patients declined further

Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

Full Text Available Chronic dacryocystitis is often seen in middle-aged and old women, especially in menopause. The opening of the obstruction of the nasolacrimal duct is the key to the treatment of chronic dacryocystitis. At present, surgical treatment is the main type of operation. The commonly used methods include the transnasal canthus skin dacryocystorhinostomy and the endoscopic dacryocystorhinostomy. With the development of technology, the application of laser technology and new lacrimal duct silicon rubber tube makes the clinical treatment of chronic dacryocystitis more perfect. Lacrimal endoscope technology can obtain more intuitive image of lacrimal duct data, to determine the nature, location and degree of obstruction of lacrimal passage and treatment plan is particularly important, is a major breakthrough in the field of diagnosis and treatment of lacrimal duct obstruction, diagnosis and treatment method is currently the most advanced in the field.

The most common cause for the failure of external dacryocystorhinostomy (DCR) surgery is the formation of granulation tissue at the osteotomy site or common canaliculus. The aims of this study were to assess the efficacy of intraoperative adjunctive mitomycin C (MMC) treatment in external DCR surgery and to compare this procedure with the standard DCR procedure alone in the long term (1 year). In this prospective, double-masked, randomized, controlled trial, patients with primary acquired nasolacrimal duct obstruction were randomized (using a random number table) into 2 groups based on surgical procedure. In the MMC group, intraoperative adjunctive MMC 0.2 mg/mL was applied to the osteotomy site for 30 minutes. The control group underwent standard DCR procedure only. The results of the DCR surgeries were assessed using objective findings (eg, cessation of excessive tearing via nasolacrimal duct irrigation and the improvement in height of tear meniscus) and subjective symptoms (asking patients to describe the degree of tearing improvement). Both the patients and the researchers who were assessing the study outcomes were masked to treatment group. One hundred eyes of 100 Turkish patients were assessed and equally randomized to the MMC (27 women, 23 men; mean [SD] age, 47.0 [7.6] years) and control (26 women, 24 men; mean age, 46.6 [8.8] years) groups. The follow-up period was not significantly different between the MMC and the control groups (13.1 [1.1] vs 13.2 [1.4] months). Significantly more eyes in the MMC group than the control group remained symptom-free throughout the 1-year follow-up period (45/50 [90%] vs 33/50 [66%]; P=0.005). Significantly more patients in the control group than the MMC group had an improvement in symptoms at the 1-year follow-up (8/50 [16%] vs 2/50 [4%] eyes; P=0.005). Based on the patency of the drainage system, the success rate was significantly greater in the MMC group than the control group (48/50 [96%] vs 42/50 [84%]; P=0.005). Based

We report surgical treatment of a patient with dacryocystitis and retinal detachment (RD), which are rare ophthalmic involvements of Wegener granulomatosis (WG). The patient was a 26-year-old man with WG. He was diagnosed as having WG 4 years ago and he has been treated by maintenance doses of predonisolone and cyclophosphamide. Rheumatoid factor and serum antinuclear antibody were negative. Cytoplasmic pattern-antineutrophil cytoplasmic antibody (C-ANCA) and renal function were normal. He was found to have nasolacrimal duct obstruction and lattice degeneration bilaterally, retinal tear with RD in the left eye and tear without RD in the right eye. No sign of vasculitis was found in fluorescein angiography. Bilateral dacryocystorhinostomy was performed without any sign of postoperative necrosis of the wound. After the surgery, epiphora and eye discharge disappeared and lacrimal passage has been maintained without obstruction. The pathological findings of his nasal mucosa and lacrimal sac showed chronic inflammation and no typical changes of WG. There was no abnormal change in the conjunctiva and sclera after an uncomplicated scleral buckling surgery. We conclude that operations such as dacryocystorhinostomy and scleral buckling surgery may be performed successfully when WG is controlled within the normal limits of C-ANCA.

Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case.

Full Text Available In this paper the authors propose an approach for measuring the impact of innovations on hospital efficiency. The suggested methodology can be applied to any type of innovation, including technology-based innovations, as well as consumer-focused and business model innovations. The authors apply the proposed approach to measure the impact of transcanalicular diode laser-assisted dacryocystorhinostomy (DCR, i.e. an innovation introduced in the surgical procedure for treating a tear duct blockage, on the efficiency of general hospitals in Slovenia. They demonstrate that the impact of an innovation on hospital efficiency depends not only on the features of the studied innovation but also on the characteristics of hospitals adopting the innovation and their external environment represented by a set of comparable hospitals.

After 13 years the patient felt the epiphora was intolerable and underwent endoscopic dacryocystorhinostomy (DCR of the left, then the right side. Intraoperatively, during the right endoscopic DCR, a Herrick lacrimal plug was found in the common canaliculus into the lacrimal sac. Postoperatively, the patient did well with improved epiphora. The Herrick plug is designed to be intracanalicular, and this case illustrates that the plug can migrate and be retained for many years. Collared punctal plugs have a lower risk of this type of complication.

Importance of imaging diagnostics and interventional therapy for diseases of the lacrimal drainage canals

International Nuclear Information System (INIS)

Bink, A.; Berkefeld, J.; Luechtenberg, M.

2008-01-01

Epiphora (continuous watering of the eyes) is frequently caused by obstruction of the lacrimal draining system. Radiographic imaging of the tear ducts after contrast injection with the DSA (digital subtraction angiography) dacryocystography technique is still the gold standard in patients with severe epiphora which does not respond to conservative therapy. Recent techniques, such as 3D rotational dacryocystography, MRI and CT are able to show the anatomic surroundings in addition to the ductal structures and are especially useful for planning endoscopic operations. Dacryocystographically assisted interventions, such as balloon dilatation or stenting of tear duct stenoses are technically feasible. Balloon dacryocystoplasty is especially successful in patients with incomplete or short distance obstructions of the nasolacrimal duct. Stenting may improve procedural success and patency rates. Minimally invasive interventional therapy is useful as an initial treatment in selected cases, however, long-term success rates may be limited and operative dacryocystorhinostomy still plays an important role. Comparative studies for evaluation of different therapeutic options are necessary. (orig.) [de

The main characteristics of the laser radiations are: directivity, monochromaticity and spatially and temporally coherence. Using the aggregation state as a criterion for classification, we describe solid, liquid and gaseous active media. Concerning the methods used to realize the population inversion, we also describe: optically, electrically and high energy particles pumped lasers. Depending on the laser media and the mode of excitation, a laser may operate in multiple ways: the continuous-wave operation, the long-pulsed operation, the Q-switched mode of operation and the mode-locked operation. The interaction of laser radiations with the living matter is based upon four main effects: the thermal, mechanical, electrical and biological effect. The main field of therapeutical use of lasers are: the management of lid tumors and intraocular tumors, dacryocystorhinostomy, the treatment of diabetic retinopathy, thromboembolic retinal syndromes, inflammatory choriretinal disease, chorioroetinal degenerations, retinal angimatosis, retinal breaks and retinal detachment, corneal diseases, glaucoma, lens diseases. Laser has also nontherapeutical applications in diagnosis and prognosis of ophthalmologic diseases.

Fenton, S

2012-02-03

PURPOSE: To determine the efficacy of dacryocystoplasty with balloon dilation in the treatment of acquired obstruction of the nasolacrimal system in adults. METHODS: Balloon dacryocystoplasty was performed in 52 eyes of 42 patients under general anaesthetic. A Teflon-coated guidewire was introduced through the canaliculus and manipulated through the nasolacrimal system and out of the nasal aperture. A 4 mm wide 3 cm coronary angioplasty balloon catheter was threaded over the guidewire in a retrograde fashion and dilated at the site of obstruction. RESULTS: There was complete obstruction in 30% of cases and partial obstruction in 70%. The most common site of obstruction was the nasolacrimal duct. The procedure was technically successful in 94% of cases. The overall re-obstruction rate was 29% within 1 year of the procedure. There was an anatomical failure rate of 17% for partial obstruction and 69% for complete obstruction within 1 year. CONCLUSIONS: Balloon dacryocystoplasty has a high recurrence rate. There may be a limited role for this procedure in partial obstructions. Further refinements of the procedure are necessary before it can be offered as a comparable alternative to a standard surgical dacryocystorhinostomy.

Methods: A head mount was used to fix the camera on the operating surgeon′s head. Due care was taken to protect the patient′s identity. The recorded video was subsequently edited and used as a teaching tool. This retrospective, noncomparative study was conducted at three tertiary eye care centers. The surgeries recorded were ptosis correction, ectropion correction, dacryocystorhinostomy, angular dermoid excision, enucleation, blepharoplasty and lid tear repair surgery (one each. The recorded videos were reviewed, edited, and checked for clarity, resolution, and reproducibility. Results: The recorded videos were found to be high quality, which allowed for zooming and visualization of the surgical anatomy clearly. Minimal distortion is a drawback that can be effectively addressed during postproduction. The camera, owing to its lightweight and small size, can be mounted on the surgeon′s head, thus offering a unique surgeon point-of-view. In our experience, the results were of good quality and reproducible. Conclusions: A head-mounted ultra-HD video recording system is a cheap, high quality, and unobtrusive technique to record surgery and can be a useful teaching tool in external facial and ophthalmic plastic surgery.

Full Text Available Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.

Management of the nasolacrimal system is usually recommended during medial maxillectomy via external approach because of reported higher rates of postoperative epiphora. Association of the endoscopic medial maxillectomy (EMM) with epiphora, however, is not clearly stated. In this study, we attempted to evaluate whether patients develop epiphora after simple transection of the nasolacrimal duct during EMM. Medical records of 26 patients who underwent endoscopic tumor resection for inverted papilloma (IP) were retrospectively reviewed. Patients who underwent EMM with nasolacrimal canal transection were included and recalled for lacrimal system evaluation. Twelve patients were eligible for inclusion and fluorescein dye disappearance test (FDDT) was performed for each patient. Patient demographics, tumor data, surgical procedures, and follow-up time were recorded. Of the 12 patients included in the study, 6 underwent canine fossa transantral approach concurrently with EMM. The mean duration of follow-up was 21.1 months (range, 6-84 months). Eight patients were graded as 0, whereas 4 patients were graded as 1 according to FDDT. All test results were interpreted as negative for epiphora. All patients were completely symptom free of epiphora. Epiphora after EMM with nasolacrimal canal transection among patients with sinonasal tumors appears to be uncommon. Therefore, prophylactic concurrent management of nasolacrimal system including stenting, dacryocystorhinostomy (DCR), or postoperative lacrimal lavage are not mandatory for all patients.

Full Text Available Purpose: To evaluate the efficacy of a sleeve technique during endoscopic dacryocystorhinostomy (DCR in primary nasolacrimal duct obstruction (NLDO patients with a high lacrimal sac. Materials and Methods: The medical records of 45 patients (49 cases undergoing endoscopic DCR for primary NLDO with a high lacrimal sac were retrospectively reviewed. In 19 patients (21 cases, the thick maxilla covering the common canalicular opening was removed using a drill and a bicanalicular silicone tube was inserted (group 1. In 26 patients (28 cases, instead of removal of the thick maxilla, a sleeve was inserted into the bicanalicular silicone tube (group 2. At 6 months postoperatively, the success rate was evaluated and the size of the intranasal mucosal ostium was measured. Results: The success rates in group 1 and 2 was 90.5% and 96.4%, respectively (P = 0.400. The intranasal mucosal ostium in group 1 and 2 measured 1.7 ± 0.7 mm and 3.1 ± 1.0 mm, respectively, and the difference was significant (P = 0.042. Conclusions: In primary NLDO patients with a high lacrimal sac, DCR inserting a silicone tube and a sleeve together had a satisfactory success rate without using a drill. In comparison with traditional surgical methods, it helped enlarge the size of the intranasal mucosal ostium.

The aims of the current review are to summarize the etiopathogenesis, symptomatology, management, complications, and outcomes of iodine-131-induced nasolacrimal duct obstructions, to propose a screening protocol and elucidate the potential avenues of future research. The authors performed an electronic database (PubMed, MEDLINE, EMBASE, and Cochrane Library) search of all articles published in English on nasolacrimal duct obstructions following radioiodine therapy. These articles were reviewed along with their relevant cross references. Data reviewed included demographics, presentations, investigations, management, complications, and outcomes. In addition, based on relevant unanswered questions and current lacunae in literature, potential avenues for further research have been elucidated. The frequency of nasolacrimal duct obstruction is reported to range from 2.2% to 18% following I-131 therapy. They are mostly bilateral and noted in patients who receive more than 150 mCi radioiodine. Exact etiopathogenesis is unknown but radiotoxicity to lacrimal sac and nasolacrimal duct is believed to be mediated through a sodium-iodine symporter protein. Although uncommon, it is important to increase awareness among treating physicians and patients receiving radioiodine therapy about the potential side effect of nasolacrimal duct obstruction. Imaging modalities are useful adjuncts in the diagnosis. Dacryocystorhinostomy is the most common modality of management with good outcomes. Nasolacrimal duct obstruction following radioiodine treatment is a distinct clinical entity. Increased awareness would facilitate timely diagnosis, management, and an enhanced quality of life for the patients.

Full Text Available BACKGROUND Dacryocystitis in infants is a serious complication of congenital, but seldom of acquired nasolacrimal duct obstructions. If conservative treatment fails, dacryocystorhinostomy (DCR appears to be effective. The indications, special clinical history and results will be reviewed. PATIENTS AND METHODS From January 2006 to December 2010, a total of 30 children prospectively were involved in the study (26 male, 4 female with persistent dacryocystitis (4 patients were treated surgically by DCR and were continuously documented. The patients ranged in age from 10 months to 14 years old (mean age 4.9 years. Included in our study were 16 children (12 male, 4 female with 4 surgically treated lacrimal ducts. RESULTS The cause of dacryocystitis was congenital obstruction in 13 children and trauma (maxillary fracture in 1 child, respectively. Of these, 2 children (15% had additional anomalies of the lacrimal system, 1 (7.6% systemic malformations and 8 out of the 30 children (26% had a family history of nasolacrimal duct obstruction. We found a functional success rate (with complete resolution of symptoms of 90% (27 out of 30 lacrimal ducts over follow-up periods ranging from 1 month to 4 years (average 1 years. 8 children probing were done and remaining 18 children were managed conservatively. CONCLUSION Patients with persistent dacryocystitis due to congenital nasolacrimal duct obstruction have a prevalence of further nasolacrimal abnormalities and a family history In the case of persistent dacryocystitis, DCR is indicated after the age of 1 year and has the same success rate in infants as in adults (90-95%.

The utility of uninterrupted navigation guidance throughout the surgery with the endoscope as the navigating tool was noted. Results: Intraoperative geometric localization of the lacrimal sac and the nasolacrimal duct could be easily deciphered. Constant orientation of the lacrimal drainage system and the peri-lacrimal anatomy was possible without the need for repeated point localizations throughout the surgery. The “look ahead” features could accurately alert the surgeon of anatomical structures that exists at 5, 10 and 15 mm in front of the endoscope. Good securing of the shunt stylet with the telescope was found to be essential for constant and accurate navigation. Conclusion: Navigation-enabled endoscopes provide the surgeon with the advantage of sustained stereotactic anatomical awareness at all times during the surgery.

Full Text Available Background: Psychiatric morbidity in human immunodeficiency virus (HIV patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. Aim: The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. Materials and Methods: A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ, mini mental status examination, hospital anxiety and depression scale (HADS and sensation seeking scale (SSS and the scores were analyzed statistically. Results: Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Conclusion: Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

Purpose: To report the finding of nasolacrimal drainage system obstruction associated with radio iodine therapy and to review clinical data and the surgical treatment outcome of this rare complication. Methods: We retrospectively analyzed ophthalmological data of patients with history of thyroid carcinoma that underwent radioactive iodine I-131 therapy and were referred to lacrimal surgery. Results: 17 patients with thyroid cancer treated with thyroidectomy and radioactive iodine I-131 therapy presented symptomatic nasolacrimal duct obstruction after 13.2 months following cancer treatment. 11 patients presented bilateral epiphora, 8 had lacrimal sac mucocele. Age range was 30 to 80 years, 10 patients had less than or equal to 49 years. The mean cumulative dose of radioiodine was 571mCi (range: 200-1200 mCi). Nasal obstruction symptoms and increased salivary glands were also present in 53% of patients. All subjects underwent dacryocystorhinostomy. Dilation of the lacrimal sac and increased intraoperative bleeding was also observed in 3 younger patients. Complete epiphora and dacryocystitis resolution after surgery occurred in 82.4%, and partial in 17.6% (3 patients that still presented unilateral relapse after correction of bilateral obstruction). Mean follow-up was 6 months (range: 2-24 months). Conclusions: Cumulative high dose of radioiodine, nasal and salivary gland dysfunction are associated with lacrimal drainage obstruction. We observed a great percentage of younger patients presenting dacryocystitis when compared to the idiopathic dacryostenosis. Radioactive iodine uptake by nasolacrimal duct mucosa with subsequent inflammation, edema and fibrosis seems to have a relationship to lacrimal duct obstruction. The knowledge of this complication is important for the study and proper management of these patients (author)

Full Text Available Introduction. Radioactive iodine therapy after thyroidectomy is the standard of differentiated thyroid cancer treatment in the modern world. Main dose-dependent side effects described in the literature include: sialadenitis, xerostomia, taste and/or odor loss, swelling of surrounding tissues. Ophthalmic complications are rarely reported. Aim. To assess the lacrimal system condition in patients after radioactive iodine therapy for thyroid cancer. Material and methods. The study included 17 patients (34 eyes. There were female patients aged 19 to 43 years (mean age was 31 years who underwent a course of radioactive iodine therapy for thyroid cancer. All of them complained of periodic or constant tearing in the period from 2 months to 1 year after therapy course. In four patients, there was a permanent or periodic mucopurulent discharge when pressing on the lacrimal sac area. All patients underwent a standard ophthalmological examination, including visual acuity testing, anterior segment biomicroscopy, ophthalmoscopy, and tear production tests. Dye disappearance test, Jones I and II tests, lacrimal pathways irrigation, and, if necessary, cone-ray computer tomography with preliminary lacrimal pathways contrasting were performed to evaluate the tear outflow abnormalities. Results. Tear production disorders were detected in 20 eyes (58.8% (among them, moderate dry eye syndrome was diagnosed in 3 cases; tear outflow pathology was revealed in 14 eyes (41.2% (namely naso-lacrimal duct obstruction and stenosis, and chronic purulent dacryocystitis. For patients with tear production pathology artificial tears were prescribed, and endoscopic endonasal dacryocystorhinostomy was performed in cases of tear outflow disturbances. Conclusion. The use of radioactive iodine in doses exceeding 80 mCi leads to the development of lacrimal system pathology: dry eye syndrome of various severity, and tear outflow disorders. Lacrimal system pathology significantly worsens

Objective: The purpose of this study was to investigate the diagnostic value of dynamic MRI dacryocystography (dMR-DCG) for the assessment of nasolacrimal drainage system (NLDS). Methods: The study population consisted of 35 patients with a history of epiphora. Each patient underwent bilateral dMR-DCG and conventional dacryocystography (DCG) to assess the NLDS. Two radiologists, who were unaware of the clinical data, evaluated the images separately for the level of obstruction at the nasolacrimal passage and the presence or absence of lacrimal sac dilatation. The findings from the dMRI-DCG and DCG images were compared. DCG was considered to be the gold standard imaging technique. Results: dMRI-DCG had a sensitivity of 90.5% and a specificity of 89.3% to detect nasolacrimal passage. In 24 out of 70 NLDS that were assessed, there was 100% agreement between the dMRI-DCG and DCG images in the detection of the obstructed level in the nasolacrimal pathway. The lacrimal sac dilatation finding detected by DCG was not observed by dMRI-DCG in only two patients, in whom there was a prior history of dacryocystorhinostomy (DCR) operation. These findings suggest that dMRI-DCG has 94.3% sensitivity and 100% specificity for the diagnosis of lacrimal sac dilatation. Conclusion: dMRI-DCG is an easily performed, minimally invasive imaging technique to identify the presence or absence of obstruction and its level, and lacrimal sac dilatation in the evaluation of NLDS. dMRI-DCG does not require the use of contrast material and ionizing radiation and provides functional information by depicting dynamic behaviour. Thus, dMRI-DCG could be useful as a reliable diagnostic imaging technique in many patients prior to surgery.

The objective of this study was to compare patients with epiphora and cataract in terms of the activity limitations they experience in daily life due to their visual disability and to validate the use of the Catquest-9SF questionnaire for epiphora patients. Seventy-two consecutively encountered adult patients with confirmed lacrimal obstruction and listed for dacryocystorhinostomy (DCR) or lacrimal intubation at the St. Erik Eye Hospital, Stockholm, Sweden, completed the Catquest-9SF questionnaire, which measures activity limitations in daily life due to visual disability. The psychometric qualities of the Catquest-9SF results obtained from this group of patients were evaluated by Rasch analysis. Rasch analysis was further employed to convert the ordinal raw data to a Rasch score for comparison with the preoperative scores of patients registered in the Swedish National Cataract Register (NCR) during March 2013. The Catquest-9SF exhibited good psychometric qualities when investigating epiphora patients, with the exception of a misfit for Item 4, the item regarding facial recognition. On the Rasch scale (-5.43 = no activity limitations to +5.01 = severe activity limitations), the mean score for epiphora patients was -0.82 while for patients listed for 1st eye and 2nd eye cataract surgery it was -0.17 and -0.76, respectively. An equivalence test confirmed that the reported visual disability of epiphora patients was not significantly different from visual disability reported by patients waiting for 2nd eye cataract surgery. The Catquest-9SF is a valid measure of visual disability in patients with epiphora. Epiphora patients experience visual disability to the same degree as patients awaiting 2nd eye cataract surgery. © 2017 Acta Ophthalmologica Scandinavica Foundation.

Proteus mirabilis and its role in dacryocystitis.

Borgman, Christopher J

2014-09-01

Dacryocystitis is a common inflammation of the lacrimal sac, usually from an underlying bacterial infection. Most cases can be attributed to common ocular flora such as Staphylococcus aureus or Streptococcus pneumoniae; however, uncommon bacterial causes such as Proteus mirabilis can still occur. P. mirabilis is a gram-negative bacillus that is found abundantly in people who have undergone long-term catheterization and is uncommonly found in or around the eyes except in people who have undergone long-term catheterization. Proteus species can cause conjunctivitis, canaliculitis, and dacryocystitis and have the ability to manifest into preseptal cellulitis; therefore, timely recognition and treatment are important to prevent potential further complications. An 84-year-old white man had several recurrences of acute dacryocystitis that had marginal improvement with empiric antibiotic treatment. Resultant culture of the ocular discharge revealed an uncommon bacterium, P. mirabilis. Successful dosing of oral antibiotics resolved the infection but ultimately the patient required an external dacryocystorhinostomy (DCR) procedure to maintain patency of the nasolacrimal lacrimal system and prevent recurrence. At 3 months after external DCR, the patient was symptom free with no recurrences. Dacryocystitis has a distinctive clinical presentation and is usually easily treated when appropriate oral antibiotics are directed at the underlying pathogen. In nonresponsive cases, culturing of the ocular discharge should be performed to identify the underlying pathogen. Cases of dacryocystitis caused by Proteus species are usually responsive to several standard antibiotics used orally in eye care; however, culturing and susceptibility testing can streamline the diagnostic and management sequence considerably in unclear or unresponsive cases. Typically, patients with dacryocystitis return to normal after appropriate treatment, but chronic recurrences and epiphora are potential sequelae

To develop surgical indications in dacryostenosis within the vertical portion of lacrimal pathways that would consider findings of single-photon emission computed tomography (SPECT) combined with X-ray computed tomography (CT). A total of 96 patients with isolated vertical-portion dacryostenosis (127 cases) were enrolled. The examination included collecting Munk's scores for epiphora, optical coherence tomography of the lower tear meniscus, lacrimal scintigraphy, and SPECT/CT. Group 1 (40 cases) was composed of patients with lacrimal obstruction on CT, group 2 (87 cases) - of those whose lacrimal pathways proved passable. There were also 3 patients (4 cases) from group 1, whose lacrimal pathways, despite being blocked on CT, were still passable on SPECT. Surgeries performed in group 1 were endoscopic endonasal dacryocystorhinostomy (DCR) (36 cases) and pathways recanalization with bicanalicular intubation and balloon dacryoplasty (DCP) (4 cases). In group 2, all patients (87 cases) underwent recanalization with bicanalicular intubation (supplemented with balloon DCP in 32 cases). Surgical results were evaluated 8-12 months after the treatment. In group 2, particular attention was paid to the concordance in locations of dacryostenosis provided by CT and SPECT scans. Favorable outcomes of endoscopic endonasal DCR were obtained in as many as 32 cases from group 1 (88.9%), while in 4 cases (12.1%) the condition relapsed. Of those patients whose stenosis was not complete on SPECT, 3 cases (75.0%) improved, 1 (25.0%) - relapsed. In group 2, favorable outcomes were obtained in 65 cases (74.7%), relapses were 22 (25.3%). A high concordance in stenosis locations by CT and SPECT was noted in 60 cases of those who improved (92.3%) and 3 cases of those who relapsed (13.6%). The value of information provided by SPECT/CT has proved high in patients with nasolacrimal duct stenosis or obstruction. A combined scan allows to establish causal relationships between anatomical changes
