External Dacryocystorhinostomy [DCR] is a well proven procedure where success ranges from 85 to 97% in patients with nasolacrimal duct obstruction as published in various journals.1-3 Inspite of excellent success rate, there are large number of cases with failure typically due to poor surgical technique, intranasal adhesions, fi brous obstruction at the common canaliculus, closure of the osteotomy, and fall of the mucosal fl ap.1,4 Development of scar tissue at the osteotomy site, seen endoscopically, is considered to be the main cause of failure.5 Kao et al6 have shown that the area of the osteotomy site gets reduced from 65.55 mm2 to 10.83mm2. The application of antifi brotic agents like mitomycin C7 or the placement of stents8 at the site of the osteotomy are thought to increase the success of the procedure, although previous studies have not demonstrated these interventions to be statistically signifi cant. Performing repeat surgery in cases of failed DCR is a daunting task owing to its disruption of normal anatomy of lacrimal sac area, fi brous adhesions and inadequate tissue availability for performance of anastomosis. Use of silicone stents in failed DCR is an useful adjunct for maintaining the integrity of anastomosis of nasolacrimal pathway, moreover it is commonly performed technique by oculoplastic surgeons all over the world. Silicone material is tissue friendly and is used in various intraocular and extraocular procedures in varying consistency. Elmorsy et al9 have shown that fi nal osteotomy size after DCR with silicone stent placement was larger in comparison to that with Aim of the Study : To describe a novel and alterna ve method of stent placement for failed dacryocystorhinistomy(DCR).
