Abstract
PURPOSE: The aim of this work is to demonstrate the outcomes of endonasal dacryocystorhinostomy (En-DCR) with anterior ethmoid sinus mucosal and posterior lacrimal sac flap anastomosing in patients with previous failed DCR.
METHODS: The clinical data of patients who suffered from recurrent epiphora after failed DCR between September 2014 and March 2018 were reviewed retrospectively. Among them, those who received the second En-DCR procedure were enrolled in this study. During the surgery, anterior ethmoidectomy was performed. Posterior lacrimal sac flap was apposed closely to the mucosal of anterior ethmoid sinus instead of nasal flap at end of the surgery. Patients were followed up more than 12 months were included, the success rate and complications were recorded.
RESULTS: Sixty-one eyes of 61 patients were enrolled in the study. The success rate of our modified En-DCR was 83.6% (51/61). Among 10 eyes with postoperative obstruction, 4 eyes caused by granuloma, 2 eyes caused by scar synechia, 2 eyes caused by membranous obstruction, and 2 eyes caused by common canalicular stenosis. No serious complications such as orbital fat prolapse, cerebrospinal fluid leak, sinusitis, or visual impairment were occurred in this study.
CONCLUSION: Endoscopic approach with anterior ethmoid sinus mucosal and posterior lacrimal sac flap anastomosing is a good choice for patients with recurrent epiphora after previous failed DCR.
