Abstract :

This retrospective study describes and evaluates the surgical outcome and operating time of powered (drill) and non–powered (Kerrisons punch) in primary endoscopic dacryocystorhinostomy (DCR). Forty patients who had undergone primary endoscopic DCR at a tertiary care center, Skims Medical collage Bemina from last six years,for correction of lacrimal system obstruction were investigated. The surgical technique involves elevation of a nasal mucosal flap, full sac exposure using either power drill or kerrison punch,and shaping of the mucosal flap to cover denuded bone and juxtapose exposed sac mucosa. Both kerrions punch and drill are wildly used in endoscopic DCR with non –conclusive knowledge abut differences in operative details as well as on the outcome. The aim of this study is to compare the surgical outcome and operating time of powered (drill) and non–powered (Kerrisons punch) in primary endoscopic dacryocystorhinostomy (DCR). The mean duration of follow–up was 11.7 months. Procedure success rate among drill group was 94 % vs. 89 % in kerrsions punch powered drill group (p=.0.74), while complications for both groups were statistical not significant (p=0.5). The mean operating time among kerrison punch group was significantly lower than in powered drill group (49 min vs. 84 min, p<0.05).Kerrison punch showed significant reduction in operating time when compared to powered drill for endoscopic DCR. No statistically significant difference was found between both groups regarding procedures� success rate and complication.
