Abstract: Dacryocystorhinostomy (DCR) is establishing a permanent anastomosis between the lacrimal sac and the nose. Through an incision on the lower lacrimal ridge, the inner lacrimal parts are exposed, and a bone window is made in the nasal bone. Then the nasal mucosa is sutured to the lacrimal sac mucosa. This procedure constitutes of an external incision in the base of the nose and inferior to the canthus, removing a bone window anterior to the midline turbinate and then anastomosing the lacrimal sac to the nasal mucosal flaps. The operation can be done with or without silicone tube intubation.
Methods: This study was performed at the Labbafinejad hospital. The data was gathered through the patients’ medical records who underwent this procedure from 1390-1394. The most important indicators in this study are age, sex, type of operation, the affected eye, previous operations on eye/eyelids/nose, chief complaint at the first visit to the hospital, type of surgeon, and the success or failure rate of surgery. All the patients were followed after 1 day, 1 week, 6 weeks, and 3 months following the DCR surgery.
Results: The results of the Dacryocystorhinostomy surgery in 198 patients were analyzed. The average age of the patients was 49.8 ± 15.99 years. Eighty-nine patients (40.6%) were males, and 130 (59.4%) were females. Eye involvement in 201 (91.8%) patients was unilateral, and in 18 (8.2%) patients were bilateral. The overall rate of subjective and objective success was 91.8% and 93.2%, respectively. The surgery’s subjective success rate was 89.9% in DCR + ST group and 93.3% in the DCR – ST group. Objective success was 89.9% in DCR + ST group and 95.8% in DCR – ST group. The overall rate of early and late failure was 1.4% and 5.9%, respectively.
Conclusion: In summary, this study shows that external dacryocystorhinostomy surgery for acquired nasolacrimal duct obstruction at a tertiary referral eye care hospital from 1390 to 1394 resulted in a high success rate. The long-term patient follow-up also revealed that the rate of early and late failure is low.
