半导体激光在经鼻泪囊鼻腔造口术中的应用

Semiconductor laser use in endoscopic transnasal dacryocystorhinostomy

目的:探讨半导体激光在经鼻泪囊鼻腔造口术中的应用价值。方法:8例鼻泪管阻塞患者在鼻内窥镜下先行鼻中隔粘膜下部分切除术或鼻息肉摘除鼻窦开放术,术中用激光光纤头发出的瞄准光确定泪囊位置,用激光切除覆盖泪囊的鼻腔外侧壁粘膜和骨质,开放泪囊。结果:术后半年鼻内窥镜检查,7例泪囊造口上皮化好、无狭窄;1例泪囊造口被瘢痕封闭,经再次激光切除瘢痕并放人扩张管,随访半年造口无封闭。结论:半导体激光能明显减少出血量,减少粘连和肉芽形成,定位准确,方法简便、快捷,值得临床推广应用。

Objective:To explore the using and value of semiconductor laser in endoscopic transnasal dacryocys-torhinostomy. Method: In 8 cases with obstruction of nasolacrimal duct,after being had submucous resection of nasal septum,nasal polypectomy or sinus resection,we used the fiberoptic light probe through! the canalis nasolacri-malis to confirmed the location of sacculus lacrimalis and resected the mucosa and bone on lateral wall of nasal cavity that covering the sacculus lacrimalis. Result; Six months after operation,the mucous was complete epithelization and ostium without stricture in seven cases. One case was covered with ulo,after reexcised with semiconductor laser and put the silicon throught the canalis nasolacrimalis,the ostium without stricture in 6 months. Conclusion; Semiconductor laser can obviously reduce bleeding,adhesion and granulation tissue,it is a good, simply and shortcut way for clinic.
