Improving the Results of Endonasal Dacryocystorhinostomy with Mitomycin C Application: A Prospective Case –Control Study

The objective of the study was to evaluate the advantage of mitomycin C in primary endoscopic endonasal dacryocystorhinostomy without stenting. Randomised case control design. Tertiary academic centre in central India. 112 patients who presented with epiphora and diagnosed as chronic dacryocystitis after syringing by ophthalmologist, were selected and randomised into two groups with or without mitomycin C intraoperative application. 112 eyes underwent endoscopic-dacryocystorhinostomy. Additional surgeries were done according to necessity. Mitomycin C was applied in concentration of 0.4  mg/dl for 5 min. Patients were followed up on OPD-basis at the end of 1st week, 1st month, 3rd month and over phone call at end of 1 year. Symptomatic improvement assessed by verbal enquiry and clinically by syringing by ophthalmologist. 8 patients underwent septal surgery in case group and 4 in control group along with 1 concha bullosa correction in the case group (p <  0.05). Nil intraoperative complications (p <  0.05) and nil postoperative complication noted (p <  0.05). Functional and anatomical patency found to be 100% at the end of 1st week in both groups, 96.5% at 3rd month in case group and 96.4% and 92.9% at 1 month and 3 month respectively in control group. Nasal endoscopy of all surgical failures showed restenosis in both case group and control g roup except 1 patient with granulation in control group. Eventhough intraoperative mitomycin C application is e...
