RESUMEN
@#AIM: To compare the intraoperative bleeding and the postoperative therapeutic effect of two nasal mucosal incisions in nasal endoscopic dacryocystorhinostomy.<p>METHODS: Retrospective study. Sixty-three patients(66 eyes)with chronic dacryocystitis diagnosed by ophthalmology and treated by nasal endoscopic dacryocystorhinostomy in our hospital from June 2016 to May 2018 were collected. According to the different grouping of the base of nasal mucosal flap, dacryocystorhinostomy was performed through nasal mucosal incision with middle turbinate axilla as base in group A, and dacryocystorhinostomy was performed through nasal mucosal incision with maxillary line as base in group B. The patients were followed up to 6mo after operation, and the intraoperative bleeding and postoperative efficiency were compared between the two groups.<p>RESULTS: There was significant difference in intraoperative bleeding between the two groups.(χ<sup>2</sup>=11.803, <i>P</i><0.05). The postoperative efficiency of patients in the two groups was not statistically significant(82% <i>vs</i> 73%, <i>P</i>>0.05).<p>CONCLUSION: The nasal mucosal incision with the middle turbinate axillary region as the base was associated with more bleeding during the operation, while the nasal mucosal incision with the maxillary line as the base was less bleeding during the operation, and there was no significant difference in the postoperative treatment effect.
