Abstract:
To observe the reliability and short-term and mid-term efficacy of a new designed multi-functional lacrimal sac nasal drainage stent on the treatment of nasolacrimal duct obstruction after endonasal endoscopic dacryocystorhinostomy ( EES-DCR ) , and to evaluate its clinical application value. METHODS: A retrospective case series study was carried out. Seventy - six patients ( 79 eyes ) with nasolacrimal duct obstruction underwent EES-DCR and a new type of multi-functional lacrimal sac nasal drainage stent was implanted. The nasal lacrimal drainage stent was pulled out 2~3mo later after surgery and the patients received 3~6mo follow-up afterwards. RESULTS: ln 79 eyes, stents were successfully implanted in 77 eyes (97. 5%). All stents of 77 eyes could be pulled out successfully 2 ~ 3mo after the operation. Sixty eyes were cured with unobstructed lacrimal irrigation and symptom of epiphora disappeared;15 eyes were improved of epiphora and mild reflux during lacrimal irrigation were found, overall effective rate was 97. 4%, 2 eyes failed in stent implantation. ln 6mo follow-up, nocomplications such as stent displacement or slip was occurred, the epithelization of anastomotic stoma was good.CONCLUSlON: Surgical technique of using the multi-function nasolacrimal stent is simple and fast, and implantation of the new designed stents has a rapid recovery with fewer complications. The usage of the new stents not only improves the success rate but also broadens surgical indications of EES-DCR, it is a safe and effective method for the treatment of nasolacrimal duct obstruction.
