在耳硬化症术中使用激光不超过 10年 ,国外多用CO2 激光切除镫骨脚及底板开窗 ,据称无内耳并发症 ,且精确、操作快 ,但术野暴露不好时不能采用。该作者根据动物实验和临床使用经验 ,在耳硬化症患者术中一些步骤中应用波长为 1.32μm,强度 2～ 4 w,每次脉冲暴露时间为 0 .3～ 0 The use of laser surgery in otosclerosis surgery is not more than 10 years, more use of CO2 laser resection of stapes feet and the floor window, allegedly no complications of the inner ear, and accurate, fast operation, but poor surgical exposure can not be used. The author based on animal experiments and clinical experience, in patients with otosclerosis during some steps in the application wavelength of 1.32μm, intensity 2 ~ 4w, each pulse exposure time is 0-3 ~ 0
