Comparison of External Dacryocystorhinostomy and Transcanalicular Multidiod Laser Dacryocystorhinostomy Results in Patients with Acquired Nasolacrimal Duct Obstruction

Abstract

Aim: Comparison of external dacryocystorhinostomy (DSR) and transcanalicular multidiod laser dacryocystorhinostomy (TK-DSR) results in acquired nasolacrimal duct obstruction cases. Methods: Data of patients diagnosed with acquired nasolacrimal duct obstruction and operated were retrospectively screened. The results of external DSR surgeries in 49 eyes of 47 patients and TK-DSR surgeries in 35 eyes of 34 patients were compared. Patients' nasolacrimal passageway clearance was checked on postoperative tenth day, and later on the first, third, sixth and twelfth months. Results: In our study, surgical success rate determined at the twelfth month was 65.3% in TK-DSR cases and 86.1% in external DSR cases. Mean operation duration was 53.02 ± 5.04 minutes in the external DSR group and 22.62 ± 3.72 minutes in TK-DSR group. In TK-DSR group, nasal synechia was seen in 6 patients (17.1%), concha burn in 2 patients (5.7%) and canalicular occlusion in 1 patient (2.8%); while hemorrhage was observed in 16 patients (32.6%) and skin fistulae developed in 2 patients (4.1%) in external DSR group. Conclusion: Despite advantages of TK-DSR, such as shortened operation time, less bleeding, no need for skin incision, and less damage to the lacrimal pump system, surgical success rates seem to be higher in external DSR. Appropriate surgical technique should be applied to appropriate patients considering the advantages of surgical techniques and success rates..
