A glued technique of external dacryocystorhinostomy.

PURPOSE: Fibrin glue was used for anastomosis of lacrimal sac and nasal mucosal flaps and was compared with the conventional suture technique in external dacryocystorhinostomy. METHODS: A prospective interventional randomized control study in which 50 consecutive patients of primary acquired nasolacrimal duct obstruction (PANDO) were equally allocated into two groups. The case group underwent glued technique of external dacryocystorhinostomy (Ext DCR) in which fibrin glue was used for the apposition of the anterior lacrimal sac and nasal mucosal flaps. In the control group, conventional technique of Ext DCR was used to suture the flaps. Functional success was assessed by improvement in epiphora and fluorescein dye disappearance test (FDDT), whereas anatomical success was assessed by lacrimal irrigation and endoscopic view of the osteotomy site. RESULTS: The anatomical success in both the groups was 92%, whereas the functional success was 92% in the case group and 88% in the control group. The difference in the success rates between the two groups was statistically non-significant. CONCLUSION: Glued technique of Ext DCR is a simple and easy alternative to suturing of the flaps. Though the final outcome was comparable in both the groups, glue can be especially useful in uncooperative cases, in cases of excessive bleeding, or in situations where the flaps are very thin or have become friable.

A Prospective Comparative Study Between Subcuticular and Sutureless Technique of Skin Closure Following External Dacryocystorhinostomy.

PURPOSE: To compare the cosmetic outcome of the surgical scar of external dacryocystorhinostomy by the subcuticular versus sutureless technique. METHODS: This was a prospective interventional randomized control study conducted at tertiary level hospital. Fifty patients of primary-acquired nasolacrimal duct obstruction were included in this study. The control group patients underwent the technique of wound closure in 2 layers, subcutaneous interrupted suture with 6-0 vicryl and superficial skin with 6-0 prolene continuous subcuticular sutures. In the case group, interrupted subcutaneous sutures with 6-0 vicryl with Steristrip for skin apposition was used. The surgical scars were assessed and graded by still photographs on a computer screen by 2 independent observers unaware of the surgical technique used at 2, 6 and 12 weeks postoperatively. RESULTS: The mean scar assessment score by the 2 observers were 2.60 (0.57), 2.04 (0.64), and 1.16 (0.89) in control group and 2.02 (0.65), 1.44 (0.70), and 0.44 (0.61) in case group at 2, 6, and 12 weeks, respectively. Scar grades were analyzed using chi-square test between the 2 group and Wilcoxon signed rank test within the group. The difference between the 2 groups were found to be statistically significant at 2, 6, and 12 weeks (P < 0.05). Thus, the technique of wound closure with steristrip lead to comparatively less scarring as compared with subcuticular technique. CONCLUSION: The authors recommend the sutureless technique of wound closure using steristrip in Ext DCR as it has superior cosmetic results as compared with subcuticular technique of external dacryocystorhinostomy.
