Surgery of the footplate may cause a number of possible complications such as cochlear hearing defects or even complete loss of hearing. This has made it necessary to look for improved techniques. When a laser is used for stapedotomy, the energy transmitted to the cochlea must be reduced to the lowest possible level. We thus investigated the carbon dioxide laser to determine whether it would prove to be more advantageous than the argon laser. Animal experiments showed that CO2 laser irradiation is well tolerated. Tests performed on isolated petrous bone resulted in the development of a new surgical instrument suitable for stapedotomy using the CO2 laser. Temperature and pressure measurements were carried out on a simplified model of the human cochlea. Our findings indicated that, with both types of laser, the irradiation required to perforate the otosclerotically thickened footplate adversely affects temperature and pressure development in the cochlea.
镫骨手术可能会引发多种并发症，如耳蜗听力缺陷甚至完全失聪。这使得寻求改进技术成为必要。当使用激光进行镫骨切除术时，传递到耳蜗的能量必须降至尽可能低的水平。因此，我们对二氧化碳激光进行了研究，以确定它是否比氩激光更具优势。动物实验表明，二氧化碳激光照射耐受性良好。在分离的颞骨上进行的测试促成了一种适用于使用二氧化碳激光进行镫骨切除术的新型手术器械的开发。在人类耳蜗的简化模型上进行了温度和压力测量。我们的研究结果表明，对于这两种类型的激光，穿透耳硬化增厚的镫骨底板所需的照射会对耳蜗内的温度和压力产生不利影响。
