不同支撑物在泪囊鼻腔造孔术中的应用比较

Comparing the various supports in dacryocystorhinogotomy

目的 探讨泪囊鼻腔造孔术中采用不同支撑物的疗效,为提高泪囊鼻腔造孔术的手术成功率寻找一种有效的辅助措施.方法 68例（87眼）慢性泪囊炎随机分为治疗组和对照组,两组均接受鼻内镜下泪囊鼻腔造孔术,治疗组置入典必殊眼膏作为支撑物,联合0.02%丝裂霉素C术后泪道冲洗.对照组置入支撑管作为支撑物,观察比较其疗效.结果 随访3个月～2年,治疗组的有效率93.18%明显高于对照组的76.74%（χ^2=4.611,P＜0.05）.两者差异有统计学意义.结论 在泪囊鼻腔造孔术中应用典必殊眼膏作为泪道支撵物,术后联合0.02%丝裂霉素C冲洗泪道是一种能提高疗效的安全有效的辅助措施.

Objective To plying various support ,and find assess the therapeutic effect of apout an effective adjuvant method to improve the success rate of dacryocystorhinotomy. Methods 68 cases （87 eyes） chronic dacryocystitis were randomly divided into Tohradex group and Contrast group. All cases were treated by the procedures of dacryocystorhinotomy under endoscope. Tobradex group applied Tabradex ointment to support lacrimal duct,combined with 0.02% mitomycin C irrigation of lacrimal duct after operation, Contrast group applied intubation to support lacrimal duct,investigated and compared the therapeutic effect. Results The following up period was lasted for 3 months to two years in two group of cases. The success rate of Tobradex group was higher than Contrast group. The difference was significant by statistics （χ^2 = 4. 611 ,P 〈 0. 05）. Conclusions Applying Tobrader ointment to support lacrimal duct,combined with 0.02% mitomycin C irrgation of lacrimal duct in dacryocystorhinotomy seems a safe and effective adjuvant procedure, and can maintain higher success rate,
