Aim: To compare external dacryocystorhinostomy (DCR) and endoscopic approaches in terms of success rate and complications. Methods: In this randomized, interventional, comparative study, ninety-four patients (108 surgeries) participated in this study, 58 cases of endoscopic dacrocystorhinostomy and 50 cases of conventional external dacrocystorhinostomy were performed between December 2013 and December 2016 in the Ophthalmology department and in association with the Otorhinolaryngology department in "Diwaniya" teaching hospital in Iraq. All the patients had detailed general medical and ocular history, and they also underwent ocular and ENT examinations to exclude any nasal pathology. The level of blockage was diagnosed by lacrimal syringing and probing. Surgery was done under general anesthesia using a hypotensive technique in all patients, and the surgical outcomes and both intra and post-operative complications were analyzed. Results: Ninety-four patients (32 males and 62 females; mean age, 56 years) underwent 108 dacrocystorhinostomy surgeries for acquired Nasolacrimal duct obstruction. The success rate associated with the endoscopic procedure was higher than that associated with the external approach [53 (91.4%) versus 41 (82.0%)]; however, the difference was not statistically significant (p=0.148). Moreover, the success rate was even better following revision in both surgical procedures [55 (94.8%) versus 42 (84.0%)] and was much better with endoscopic type and showing a nearly significant value (P=0.064). The odds ratio and 95 % confidence interval were 3.49 and (0.87-13.97), respectively, which seems to demonstrate that endoscopic surgery is associated with approximately 3.5 times better successful rate in comparison with open surgery. The patients that wished to perform surgical intervention for the other eye were associated significantly more with the endoscopic procedure compared with the open procedure [54 (93.1%) vs. 40 (69.0%), respectively, (P=0.043), OR=3.38, 95% CI (0.99-11.54)] Conclusion: The endoscopic approach offered a better operation success rate for acquired Nasolacrimal duct obstruction compared with an external approach

PURPOSE: To evaluate the efficacy of endonasal revision using triamcinolone-soaked nasal packing in patients exhibiting recurrence of epiphora after endoscopic dacryocystorhinostomy. CASE SUMMARY: Four patients (4 eyes) who presented with the chief complaint of recurrence of epiphora after endoscopic dacryocystorhinostomy underwent endonasal revision under local anesthesia. On nasal endoscopy, granulation tissue and membranous tissue around the osseous foramen was removed during endonasal revision. According to the operator's judgement, the osseous foramen was additionally expanded. Following insertion of a silicone tube, triamcinolone-soaked nasal packing was used for intra-nasal packing. The silicone tube was removed after follow-up of more than 12 weeks. Immediately after removing the silicone tube, there was free passage of saline on lacrimal syringing as well as complete resolution of epiphora. At over 6 months of follow-up after tube removal, there was no recurrence of epiphora in any of the 4 patients. CONCLUSIONS: Triamcinolone-soaked nasal packing may be considered in patients with failed endoscopic dacryocystorhinostomy.

Background: To compare the post operative ostial patency at the rhinostomy site in the patients undergoing the primary endoscopic dacryocystorhinostomy, using Mitomycin-C application and Merocel packing. Methods: The patients visiting the Otorhinolaryngology out patients department at the tertiary referral hospital were included in this study. The study was prospective in nature and comprised of 50 patients suffering from primary dacryocystitis. Endonasal endoscopic dacryocystorhinostomy was done in the patients suffering from the chronic dacryocystitis with postsaccular obstruction of lacrimal system. The patients were divided in two equal groups containing 25 patients in each group. In first group (Group- A) Mitomycin-C (0.5 mg/ml for 15 min) was locally applied at the rhinostomy site and nasal cavity was packed with bactigras after the surgery, whereas in the second group, nasal cavity was packed with Merocel after reposition of the flap without application of any drug. Follow up was done every week in the first month, then monthly till the six months after the surgery. The post operative results were compared in terms of ostial patency at the rhinostomy site at one month, three months and six months of follow up. The surgical technique used remained same throughout the period of study. Results: The post operative ostial patency of rhinostomy stoma was better in the group of the patients undergoing application of Mytomycin-C at the rhinostomy site as compared to the packing of the nasal cavity with Merocel. The difference between both the groups was statistically significant. The rhinostomy created was free from synachiae and granulation tissue formation on follow up examination in the group of the patients having application of Mitomycin-C at the time of surgery. Ultimately the ostial patency was better in the patients having application of Mitomycin-C. Conclusion: Mitomycin-C has statistically significant beneficial effect in the maintenance of ostial patency after primary endonasal endoscopic dacryocystorhinostomy as compared to the merocel packing alone after the surgery.
Résumé
Aim: The study aims to report a single trainee’s experience of learning and performing endoscopic endonasal dacryocystorhinostomy (En‑DCR). Settings and Design: This study was a retrospective, interventional case series. Subjects and Methods: Fifty‑four eyes of fifty patients presenting at a tertiary eye care center over 1 year were included in the study. All cases underwent endoscopic DCR with mitomycin‑C and silicone intubation. The parameters studied included demographics, clinical features, intraoperative details, and postoperative ostium evaluation. Stent removal and nasal endoscopy were performed at 6 weeks and a further ostium evaluation at 3 and 6 months following surgery. Anatomical success rate was defined as patent irrigation, and functional success rate was defined as positive functional endoscopic dye test and absence of epiphora. Results: Fifty‑four eyes of fifty patients were operated, and three cases were lost to follow‑up after surgery. The mean age at presentation was 34 (4–75) years. Clinical diagnosis included primary acquired nasolacrimal duct (NLD) obstruction in 72% (39/54), acute dacryocystitis in 15% (8/54), failed DCR in 7% (4/54), and persistent congenital NLD obstruction in 5% (3/54). The first five cases needed intervention by the mentor for superior osteotomy. Common variations in anatomical landmarks were posterior location of sac, large ethmoidal bulla, high internal common opening, and thick maxillary bone. Surgical time taken in the last 27 eyes was significantly lesser compared to the surgical duration taken in the initial 27 cases (P < 0.05). Anatomical and functional success rate was 94% (48/51) at 6 months follow‑up period. Conclusions: Endoscopic En‑DCR has a good success rate when performed by oculoplastic surgery trainees. Nasal anatomical variations, instrument handling, and adaptation to monocular view of endoscope are few of the challenges for beginners. Structured skill transfer can help trainees to learn and perform En‑DCR with acceptable success rates.
Résumé
Chronic dacryocystitis results very often from obstruction to the nasolacrimal duct. It manifests as epiphora or watering of the eyes. The lacrimal sac gets expanded and also the wall of the sac gets thickened as a result of collection of mucopus due to obstruction of the nasolacrimal duct. Treatment of chronic dacryocystitis is by a surgical approach which consists of making an opening between the lacrimal sac and the nasal cavity above the obstruction. This operation is called dacryocystorhinostomy which can be done by external approach or nasal endoscopic approach. The intranasal or nasal endoscopic approach is the more functional route of surgery because it preserves the lacrimal apparatus as near normal as possible. Hence this surgery is being advocated as the first line of treatment for epiphora of chronic dacryocystitis. Experience of nasal endoscopic dacryocystorhinostomy done at Government Medical College, Government General Hospital, Nizamabad, Telangana is being reported with comparison of results published in literature.
Résumé
PURPOSE: To evaluate the correlation between clinical manifestation of patients with nasolacrimal duct obstruction and pathological characteristics of lacrimal sac and dacryolith found during endoscopic dacryocystorhinostomy. METHODS: This retrospective study included 158 patients (189 eyes) who received endoscopic dacryocystorhinostomy. We defined lacrimal dacryolith by gross discovery in the lacrimal sac during surgery or findings during pathological examination as dacryolith or calcification, including size and distribution in pathology slides. We correlated the relationship between the patients' clinical manifestations, surgical results, lacrimal sac's pathological findings including calcification, inflammation and fibrosis, and pathological findings of lacrimal sac dacryolith. RESULTS: Dacryolith was found in 61 eyes (32.3%) and among them, grossly found in 13 eyes (6.9%). Dacryolith's filling defect on dacryocystography was found in 17 eyes (9.0%) and based on grossly found dacryolith, dacryocystography's sensitivity and specificity were 58.8% and 1.7%, respectively. The average size of dacryolith was 0.3 +/- 0.8 mm2 with an average distribution of 20.1 +/- 17.9%. Distribution of dacryolith and the proportions of inflammatory cells and fibrosis in the lacrimal sac were negatively correlated (p < 0.05). The size of dacryolith and the proportions of fibrosis in the lacrimal sac were also negatively correlated (p = 0.008). In cases where the proportion of calcification in pathology slides was over 50%, the duration of symptoms in the calcification-dominant group was shorter than in other groups (p = 0.006). The success rates of endoscopic dacryocystorhinostomy with dacryolith and without dacryolith were 91.8% and 80.5%, respectively (p = 0.046). CONCLUSIONS: The patients with lacrimal sac dacryolith in nasolacrimal duct obstruction showed shorter duration of symptoms, lower fibrosis of lacrimal sac, and higher surgical success rates than the other cases. Therefore, additional research may be necessary to determine the mechanism of dacryolith formation and early treatment in nasolacrimal duct obstruction with lacrimal sac dacryolith.

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.
