耳软骨代泪囊治疗泪道阻塞

Lacrimal Passages Block Treated with Ear-cartilage Instead of Lacrimal Sac

使用自体耳软骨治疗陈旧性泪小管断裂、无泪囊、小泪囊及鼻腔泪囊粘膜吻合术后失败所致泪溢30例。根据泪道阻塞的不同部位和程度,将耳软骨制成管形,置于泪小管和鼻粘膜之间,并固定缝合。随访1～5年,耳软骨不被吸收和改变形状,也无排斥反应,有效率为96％。

Two third thick skin free of ear-cartilage was used to treat epiphora after long-standing canalicular laceration, port-dacsislactomy, microlacrimal sac failed of dacry-ocystorhinostomy. According to different location and severty of lacrinal passages block and suture the tube-like ear-cartilage made preoperatively to the space between canaliculus and nasalmoucous. Annular silicone tubing was inserted into the upper and lower canaliculus and the tube removed 6 months post-operatively. We treated 30 coses with the procedure described as above from 1985-1995 and followed up for l-5years. The result was satisfactory, and earcartilages not absorbed change in form or ejection. The success rate'was 96%. It worths application extending dissemination.
