Purpose: In patients with nasolacrimal duct obstruction, the outcomes of surgery were evaluated according to the type or presence of flaps.
Methods: In total, 509 eyes were compared retrospectively: 178 eyes in patients treated without flaps, 126 eyes in patients treated using nasal mucosa flaps, and 205 eyes in the patient group using nasal and lacrimal sac mucosal flap were compared retrospectively. We analyzed the factors of success according to the surgical method by comparing granulation and bony ostium obstruction at 1, 3, and 6 months after surgery in each group.
Results: At 6 months after surgery, granulation was found in 6 eyes (2.93%) in the nasal and lacrimal sac mucosal flap group, 5 eyes (3.96%) in the nasal mucosal flap group, and 15 eyes (8.42%) in the group treated without flaps. Bony ostium obstruction was found in 3 eyes (1.46%) in the nasal and lacrimal sac mucosal flap group, 4 eyes (2.38%) in the nasal mucosal flap group, and 6 eyes (2.81%) in the group treated without flaps. The anatomical surgical success rate of patients treated with nasal and lacrimal sac mucosal flaps was 95.61%, which was higher than those of patients treated with nasal mucosal flaps (92.86%) and without flaps (88.20%). The functional and anatomical surgical success rate was 94.15% in the group treated with nasal and lacrimal sac mucosal flaps, 88.89% in the group treated with nasal mucosal flaps, and 84.83% in the group treated without flaps.
Conclusions: Endonasal dacryocystorhinostomy using the nasal and lacrimal sac mucosal flap is an effective method that minimizes the risk of granulation and bony ostium obstruction.
