Abstract

ABSTRACT: Purpose : To evaluate the efficacy of tightening of lateral portion of orbicularis oculi muscle in patients with functional nasolacrimal duct obstruction (FNLDO). Methods : This is an interventional cross-section study for evaluation of effect of orbicularis oculi tightening procedure in patients with FNLDO. Patients with unexplained epiphora, open lacrimal system in syringing and evidences of lacrimal pump weakness in lacrimal scintigraphy underwent surgery. In this procedure, a stripe of preseptal and pretarsal orbicularis muscle was dissected, slightly resected and secured to the periosteum of lateral orbital rim. Each subject completed a questionnaire about the intensity of epiphora before surgery and 1, 3 and 6 months after surgery. Furthermore, fluorescein dye disappearance test (FDDT) was performed before surgery and repeated in the follow-up visits. At last visit, the pre- and post-operative data were analyzed and compared. Results : Fifteen eyes of 12 patients (5 males and 7 females) with the mean age of 56.7 years included in the study. Severity of epiphora and tearing effect on daily life were significantly improved following the operation. FDDT result was improved significantly after 1 month follow-up in all eyes (15 eyes), at 3 months follow-up in 80% of eyes (12 eyes) and at the end of the 6th month in 66.7% of eyes (10 eyes). Subjective and objective success rates were 87% and 80%, respectively. No significant complications or side-effects were observed. Conclusion : Tightening of lateral portion of preseptal and pretarsal orbicularis muscle seems an effective, safe, and easy procedure to decrease epiphora in patients with FNLDO.
