目的:观察鼻内窥镜下泪道浚通联合硅胶管逆行植入和丝裂霉素C(MMC)应用治疗泪道阻塞的手术疗效。方法:鼻内窥镜下利用泪道浚通联合类Y形硅胶管规范泪道逆行植入和MMC应用,留置Y形管3mo,跟踪观察并统计其中106例106眼的治疗结果。结果:鼻内窥镜下泪道浚通后MMC应用,置留、拔管操作特别简单容易,创伤甚微。全部治疗在门诊完成,期间患者正常生活、工作、学习。3a以上随访治疗结果:有效以上率96.2%(102眼);显效以上率92.5%(98眼);治愈率84.9%(90眼);无效3.8%(4眼)。结论:鼻内窥镜下泪道浚通联合硅胶管逆行植入和MMC应用技术是治疗泪道阻塞的首选与补充方法,损伤小,成功率高,并发症少,手术费用低。

AIM:To investigate the surgery effect of lacrimal passages dredging,silicon tube implantation and mitomycin C (MMC) retrograde treatment by endoscopy for lacrimal duct obs-truction. METHODS:Totally 106 cases underwent the lacrimal passages dredging,Y-shaped silicon tube implantation, and mitomycin C application after 3 months,and the surgery effect were observed. RESULTS:Lacrimal passages dredging,silicon tube implantation and mitomycin C retrograde treatment by endoscopy extubation,the operation had easy procedure, and very little trauma.A normal life,work,study were recorded.Following-up 3 years:the effective rate of 96.2%or more were in 102 eyes,marked effect accounted for 92.5%(98 eyes),cure rate was in 90 eyes(84.9%) and invalid in 4 eyes(3.8%). CONCLUSION:The above technique is the preferred and supplementary treatment method for lacrimal duct obstruction,which also have less damage,higher success rate,fewer complications and lower operation costs.
