作者认为,镫骨切除的方法虽然有多种,且多数也有一定效果,但尚不能解决术中存在的全部问题。保守性镫骨手术有底板切除与底板部分切除,因其保存了镫骨“拱”(镫骨的上部结构)。关于是否保存镫骨“拱”的问题早已存在争论,目前多数术者趋向于将其去除,把镫骨上部结构当作无用之物随便舍弃,而代之以金属或塑料的人工听骨小柱。作者凭其个人经验认为,长期使用人工听骨装置之效果并不理想,因此提出一种保守性镫骨手术,将镫骨“拱”变为有用之物而加以保存,称之为镫骨“后拱”成形术。十年中作者根据保存镫骨的三条原理及十条准则进行镫骨“后拱”成形术,凡是第一次手术的病例有85%以上可以采用这种方法。
The author believes that although there are many methods of stapes resection, and most have some effect, but still can not solve all the problems in the operation. Conservative tarsal surgery with floor resection and partial removal of the floor, because it preserves stapes “arch” (stapes superstructure). The question of whether or not to save stapes “arch” has long been debated. At present, most surgeons tend to remove it and use stapes superstitiously as a useless object, but replace it with a metal or plastic artificial ossicle . The author, based on his personal experience, believes that the long-term use of artificial bone devices is not ideal, and therefore proposed a conservative stapes surgery, stapes “arch” into something useful to be saved, called stapes “ Posterior arch ”angioplasty. In ten years, the author performed stapes “posterior arching” according to the three principles of stomatology preservation and ten criteria. This method can be used for more than 85% of all cases of the first operation.
