鼻泪管阻塞钻切术的改良研究及临床观察

Clinical Observation for the Improved Operation on Removed Nasolacrimal Obstruction

目的:观察使用自行设计改良的鼻泪管阻塞钻切术治疗慢性泪囊炎的疗效.方法:采用自制的环钻器等器械切除鼻泪管阻塞物,并置入自行设计的'Y'形网眼硅胶管防止再阻塞.结果:120眼中,术后3个月随访,109眼(90.83%)痊愈,4眼(3.33%)好转,7眼(5.84%)无效,总有效率94.16%,其中有50眼术后1～3年进行了随访观察,结果泪道冲洗通畅(含尚通畅)40眼(80%),不通畅10眼(20%).结论:与传统的鼻泪管阻塞钻切术比较,近期、远期疗效均有极明显提高,(P＜0.01);与泪囊鼻腔吻合术相比,有操作简单和易于掌握、推广,特别适用于农村医院的优点,故受到基层及农村医师的欢迎.

Objective:We have used the improved operation for removed nasolacrimal obstruction to kreatchronic decryocystitis.

The gencral curative rate was 94.16%. Among which 50 eyes of after operations have studied for 1~3 years. irrigation of lacrymal passages passages patency(contain part of patency)was 40 eyes(80%),non-patency 10 eyes(20%).Conciusions:Compared to decryosystoriy the operation is simple and grasped easily.We think the operation is worthy to extend specially in country hospital.
