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
