Abstract :
Aim: To evaluate the comparison of efficacy and adverse effects between endonasal and external dacryocystorhinostomy(DCR).
Materials and Methods: Prospective, interventional, comparative study for 76 patients of symptomatic non-traumatic naso-lacrimal duct obstruction. Patients with previously failed surgery were excluded. 36 patients underwent recanalization with endonasal approach using endoscope (0, 30 and 70 degree) equipped by video endoscopy for direct visualization on monitor and 40 patients underwent external dacryocystorhinostomy. Follow up done on day 1, 7, 21, 3 months, 6 months and one year post-operatively. Evaluation was done on the basis of symptomatic relief and patency of nasolacrimal duct on lacrimal syringing. Data was analyzed by chi square test and unpaired t- test. P value 0.05). Surgical time was significantly less in endonasal DCR than in external DCR (p
