Endoscopic dacryocystorhinostomy: outcomes using mucosal flap preserving technique.

Currently, transnasal approaches are preferred widely for treating chronic dacryocystitis. Restenosis which count for the most common causes of failure in endoscopic dacryocystorhinostomy (EDCR) reduces the success rate. We intended to make a large fistula, potentially minimizing granulation tissue, and synechiae by means of creating a large bony ostium and preserving mucosal flaps and intubation with silicone tube (STI). In this study, long-term follow-up results of EDCR with mucosa preservation were discussed. 126 patients underwent endonasal DCRs from January 2004 to March 2009. A large ostium was created preserving mucosa; nasal and lacrimal flaps were approximated and the new ostium was stented with silicone tube. Surgical success rate was 93 % with STI and with preservation of nasal and lacrimal flaps. In conclusion, EDCR is an easy surgical procedure with low complication rates. Intranasal pathologies can also be corrected in the meantime. Success depends on creating a large bony ostium and preventing restenosis. EDCR preserving nasal and lacrimal flaps with STI is recommended as an alternative procedure in chronic dacryocystitis with high success rates.
