External dacryocystorhinostomy treatment complexity three types of children dacryocystitis

Abstract

Objective To investigate the application via the external route dacryocystorhinostomy (EXT-DCR) treatment of the feasibility in all ages, safety and clinical efficacy with purulent complexity dacryocystitis in children. Methods From August 2009 to January 2016, 27 children patients (28 eyes) with complex dacryocystitis were divided into three types: congenital complex where lacrimal bone lacrimal duct obstruction with development abnormal in 16 patients (17 eyes); dacryocystitis trauma caused 8 cases (8 eyes); EXT-DCR had undergone surgery failure or relapse in 3 cases (3 eyes). The age ranges of those patients were 6 years and 8 months to 14 years. EXT-DCR or combined with annular tears trail superfine silicone tube catheter surgery were performed under systemic anesthesia. Followed up time was 1 month to 12 months after surgery. Results Total efficiency was 92.5% (26/28) postoperatively with two cases failed. Where in complex congenital lacrimal duct obstruction with bone lacrimal duct abnormalities were the best, lacrimal patency, no purulent secretions and tears, the cure rate was 100%; traumatic dacryocystitis and EXT-DCR after failure or re-recurrence in 1 case (2 eyes), after surgery was no longer with purulent discharge, mild tears, lacrimal duct patency but a little resistance, the effective rate of 100%, the cure rate of 81.9% (9/11). Conclusions EXT-DCR or combined with lacrimal catheterization is an effective method to treat three types of children complexity dacryocystitis, there is no need to limit age. DCR is mature surgery method for 6 years old and above dacryocystitis. Key words: External dacryocystorhinostomy; Complexity dacryocystitis; Children
