鼻泪管阻塞钻切术的改良研究及疗效观察

目的 使用自行设计改良的鼻泪管阻塞钻切术治疗慢性泪囊炎。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,故受到了基层及农村医师的欢迎。

Clinical observation of improved stricturotomy of naso lacrbnal duct on chronic dacrycystitis

Objective To investigte the effect of improved sricturotomy of naso lacrimal duct on chronic dacrycystitis. Methods We removed the obstructions in the nasolacrimal duct with self - made trephine in 120 eyes, then placed the Y shaped silica gel tube with mesh into nasolacrimal duct to prevent postoperative obstruction. Result Postoperatively, All the patients were followed up for 3 months. 109 eyes (90. 83%) were cured,4 eyes (3.33%) were improved,7 eyes (5.84%) showed noneffective. The effective rate was 94. 16%.50 eyes were followed up for 1 to 3 years.40 eyes (80%) among them were unobstructed or party unobstructed by using irrigation of lacrimal passage.The short - term and Long - term effect of the improved stricturotomy of nasolacrimal duct were significantly better than the conventional one. Conclusion The improved stricturotomy of nasolacrimal duct is a simple and effective method to cure chronic dacrycystitis.
