The Effectiveness of Simultaneous Lateral Tarsal Strip With Endonasal Dacryocystorhinostomy for the Treatment of Nasolacrimal Duct Obstruction and Lower Lid Laxity

초록

Purpose: The aim of this study was to evaluate the effectiveness of simultaneous lateral tarsal strip procedure (LTS) and endonasal dacryocystorhinostomy (DCR) for the treatment of nasolacrimal duct obstruction and lower lid laxity. Methods: We conducted a retrospective, interventional study of concurrent DCR with LTS for patients with nasolacrimal duct obstruction and lower lid laxity performed between March 2009 and July 2011 by a single surgeon (S.H.B.). Patient age, sex, the results of dacryoscintigraphy, time of tube removal, follow-up duration, and cause of failed surgery were recorded. Lower eyelid laxity was evaluated by a medial distraction test. Results: A total of 29 eyes in 17 patients were included in the study. The mean age was 61.1 +/- 11.8 years (range 41 to 81 years). The mean degree of lower lid laxity was 2.4 +/- 0.5. Dacryoscintigraphy showed presac delay in 22 eyes (75.9%). The tube was removed after 11.3 +/- 1.9 weeks. The primary anatomical success rate was 89.5% (27 eyes) and the functional success rate was 86.2% (25 eyes). Membranous obstructions were the cause of failed surgery in 2 patients, but both patients remained symptom free after revision surgery with a diode laser. Conclusions: Concurrently performed DCR with LTS can be an effective tool for the treatment of nasolacrimal duct obstruction and lower lid laxity. It is recommended for examining lid laxity carefully using lid distraction test in patients with epiphora.
