ANALYSIS OF DIFFERENT APPROACHES OF DACRYOCYSTORHINOSTOMY

Aims & Objective: To compare the overall success rate and complications of Endoscopic Dacrocystorhinostomy (Endo-DCR) with External approach Dacrocystorhinostomy (DCR). Materials & Methods: This study is based on randomization and comparison of, 50 cases of mechanical Endonasal Dacrocystorhinostomy & 30 cases of conventional External Dacrocystorhinostomy . These were performed from January 2023 to April 2024 in the department of Ophthalmology in collaboration with department of Otorhinolaryngology, Amaltas Institute of Medical Sciences, Dewas, Madhya Pradesh. All patients were examined in detail. Level of blockage was assessed by lacrimal syringing & conrmed by a Dacryocystography. Surgery was done under local anaesthesia .Children and uncooperative patients were given general anaesthesia. For EndoDCR surgery, 0 & 30 degree rigid endoscope was used. In selected cases silastic sheet were used. The surgical outcomes and complications were analysed. Results: Success and clinical relief were comparable in both the approaches. Endo-DCR surgery was found to take a shorter time to perform than external DCR surgery. The follow-up period was comparable in both groups. Patients were more satised in the Endo -DCR group. Conclusion: Endo-DCR surgery is an alternative to the conventional external DCR surgery for the treatment of primary acquired nasolacrimal duct obstruction . The success rates are equivalent , lesser surgical time and adequate patient satisfaction are an additive.
