改良鼻内窥镜下泪囊鼻腔造孔术的临床观察

Modified endoscopic dacryocystorhinostomy

目的：探讨改良鼻内窥镜下泪囊鼻腔造孔术的方法及疗效。方法：常规于鼻内窥镜下制作骨孔后，制作较大的泪囊黏膜瓣，并采用自制的前针孔缝合针将泪囊、鼻腔黏膜瓣重叠缝合固定于内眦部皮肤的深面。结果：随访3—21个月，42例、56眼中，治愈38例、51眼，好转3例、4眼，无效1例、1眼。治愈率为91．1％．总有效率为98．2％。结论：鼻内窥镜下泪囊鼻腔吻合术可有效地防止吻合口远期瘢痕挛缩闭锁．具有较好的疗效。

Objective： To investigate the role of modified endoscopic dacryocystorhinostomy. Methods： A bone pore and a large membrane flap of dacryocyst were made under endoscope, and the membrane flaps of dacryocyst and nasal cavity were sewed up and fixed to the deep surface of the inner canthus by self-made needle in 42 patients （56 eyes） with chronic dacryocystitis. Results： Followed up from 3 to 21 months, 51 eyes were cured, 4 released, 1 ineffective. The cure rate was 91.1%, and the total response rate was 98.2%. Conclusion： Endoscopic dacryocystorhinostomy has salutary effect for avoiding long-term anastomotic aresia.
