目的:观察与探讨经鼻蝶穿刺垂体瘤半导体激光间质内热疗术的方法与长期疗效.方法:采用805nm半导体激光,输出功率25W,CT或X线引导下经鼻蝶穿刺将光导纤维导入垂体瘤中心分次热凝.结果:3例术后症状皆改善,内分泌指标正常.1例术后1年肿瘤消失,1例术后2年开颅手术.结论:本术式具有操作简单、方便快捷、定位准确、损伤轻、病人痛苦少恢复快、并发症少、经济安全等特点.

Objective: To study the method and long-term curative effect of diode laser interstitial heat therapy for pituitary tumor by transnasal-sphenoidal approach conducted by CT or X ray. Methods: 805nm diode laser, output power of which is 25W, optical fiber is conducted by transnasal-sphenoidal approach through CT or X ray to have heat therapy. Results: Symptoms get better for all 3 patients, and endocrine indexs are normal. 1 patient has no pituitary tumor 1 year after operation, and 1 patient is made craniotomy 2 years after operation. Conclusion: This methods have advantage of simple manipulation, accurate location, slight injury, less complication, less painful and economics.
