ABSTRACT

OBJECTIVE To present the modified intranasal endoscopic dacryocystorhinostomy (MIEDCR) and the clinical results. To discuss the modified operative technique and its purpose. METHODS A total of 31 cases (35 eyes) with chronic dacryocystitis who underwent MIEDCR were included in this study. There were 27 female and 4 male. The age was ranged from 9 to 70 years (mean 31 years). The preoperative dacryocystography was taken in all cases. The follow up time was 6 to 20 months. RESULTS Among the 31 cases with chronic dacyocystitis, 4 patients suffered bilateral chronic dacyocystitis. Dacryocystitis related to nasal endoscopic surgery was found in 2 cases (2 eyes). Four cases (5 eyes) had prior laser lacrimal duct surgery. Two patients had external dacrypcystorhinotomy experience. 34 MIEDCR procedures (97.1 %) were successful. Twenty eight patients (32 eyes) were free of their symptoms and kept stoma patency. The shift of mucosal flap was found in one case when Merocel was removed. The rhinostomy of another 2 cases were closed due to mucosal scar and one of them received revision surgery. There were no operative complications. CONCLUSION The preserved nasal mucosal flap which was replaced over the denuded bone would avoid scar formation and hyperostosis and is benefit to gain a satisfied and good clinical effects of dacryocystorhinostomy.
