目的：比较两种鼻黏膜切口在鼻内镜下鼻腔泪囊吻合术中出血情况和术后治疗效果。

方法：回顾性研究。收集2016-06/2018-05在我院眼科确诊为慢性泪囊炎并接受鼻内镜下鼻腔泪囊吻合手术治疗的患者63例66眼。根据鼻黏膜瓣基底部位的不同分组，A组以中鼻甲腋为基底的鼻腔黏膜切口行泪囊鼻腔吻合术，B组以上颌骨线为基底的鼻腔黏膜切口行泪囊鼻腔吻合术。随访至术后6mo，比较两组患者术中出血和术后疗效。

结果：两组患者术中出血情况有差异(χ²=11.803，P<0.05)，术后有效率比较无差异(82% vs 73%，P>0.05)。

结论：以中鼻甲腋为基底部的鼻腔黏膜切口，术中并发出血较多； 而以上颌骨线为基底的鼻腔黏膜切口，术中出血较少。两组患者术后疗效无差异。

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.

RESULTS: There was significant difference in intraoperative bleeding between the two groups.(χ²=11.803, P<0.05). The postoperative efficiency of patients in the two groups was not statistically significant(82% vs 73%, P>0.05).

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.
