由于镫骨直接毗邻耳蜗及前庭,镫骨手术可能引起诸如听力减退,甚至完全听力损失等许多并发症。Thoma进行了CO_2激光应用于镫骨底板手术实验,包括三个步骤:一是借助于脑干诱发电位测听法,研究使用激光后的阈值变化的动物实验。其次通过温度测定及外科方法,在有正常底板的尸体颞骨岩部实验。其三是在简化耳蜗模型上,进行了关于人耳蜗的温度和声压测定。测验表明在CO_2激光照射期 Due to the direct contact of the stapes with the cochlea and vestibule, stapes surgery can cause many complications such as hearing loss and even complete hearing loss. Thoma conducted a CO 2 laser application in the stapes operation. This involves three steps. One is to study the use of a brainstem response potential audiometry to study animal experiments using threshold changes after a laser. Second, through the temperature measurement and surgical methods, in the normal floor of the cadaveric petrous bone rock experiment. The third is to simplify the cochlear model, carried out on the human cochlea temperature and sound pressure measurements. The tests showed that during CO2 laser irradiation
