Purpose: To assess the results of external dacryocystorhinostomy and bicanalicular silicone tube intubation (EDSR+STI) operations in our patients with acquired nasolacrimal duct obstruction.
Materials and Methods: A total of 80 EDSR+STI operations that were performed under general anaesthesia on 74 patients with acquired nasolacrimal duct obstruction aged 9 to 62 (median 36,9) were evaluated retrospectively.
Results: Thirteen patients (17,5%) were male and 61 (82,5%) were female. Seventy-nine of the 80 operations were initial procedures and in these procedures 73 (91,25%) open passages were obtained. Median postoperative follow-up period was 7,4 months (3 to 32 months). One (1,25%) procedure was made for restoration of a complication of a patient who was operated in a different center and in this patient open passage was obtained as well. In six patients (7,5%) eyes passages were closed. Four of these patients who were younger than 50 years old were reoperated and in two of them (50%) open passages re-obtained. Overall in 76 (95%) of the 80 nasolacrimal duct obstruction the passages were open. In one (1,25%) eye cutaneous fistula was developed and was repaired successfully. In five (6,25%) eyes punctum erosion were observed. The most important postoperative early complaint epistaxis was seen in nine (11,25%) procedures.
Conclusion: External DSR+STI is a safe and effective procedure and it may be performed as an initial operation in patients with acquired nasolacrimal duct obstruction
