改良泪囊鼻腔吻合术的设计及远期疗效观察

The study on project and curative eftect of improved dacrystorhinostomy.

目的观察改良泪囊鼻腔吻合术中术后并发症的疗效。方法对96例(96眼)慢性泪囊炎随机分为A、B两组。A组,传统泪囊鼻腔吻合术48例;B组,改良泪囊鼻腔吻合术48例,术后用鼻内窥镜检查泪囊鼻腔吻合口形状,泪道通畅情况。结果术后随诊3年,A组术后1年、2年、3年泪道堵塞发生率10.42%(5/48)、14.58%(7/48)、18.75%(9/48)。B组术后1年、2年、3年泪道堵塞发生率2.08%(1/48)、6.25%(3/48)、8.33%(4/48)。结论改良泪囊鼻腔吻合术后吻合口位置较低、骨窗较大、术后发生再堵塞的可能性较小,术后并发症少。

Objective % observe the treatment effect and complications after dacryoly storhinostomy（ EXTDCR）on chronic dacryocystitis. Methods 96 patients with chronic dacryocystitis were randondy divided into A and B groups（n = 48）.Group A accepted EXTDCR,group B accepted improved EXTDCR, the shape of sewing up the incision and lacrimal passage were observed in nasal speculum after the operation. Results Total cases were fullowed up 6 - 36 months after operation in group A. The rate of obstruction of lacrimal ducts is respectively 10. 42 % （ 5/48 ）, 14,58 % （ 7/48 ）, 18.75 % （ 9/48 ） after followed up one year,two years and three years. But in group B,it is 2,08% （1/48）, 6.25 % （3/48） and 8.33 % （4/48）, Conclusions hnproved dacrystorhinostomy is a surgery with lower sewing up the incision and larger bone window,and It can reduce the incidence of obstraction of naso-lacrimal tinct and complications.
