前言镫骨底板摘除术不仅为耳硬化症聋的首选疗法,其应用范围日益广泛,如中耳畸形、鼓室硬化症、以及某些慢性化脓性中耳炎的炎症业已消除而伴听骨链内固定影响听力的患者均可采用此术。为了进一步了解镫骨手术后的中耳和内耳可能发生的变化,我们用猫作了实验性的镫骨手术,观察卵圆窗移植物生长的反应,前庭误入异物以及镫骨底板摘除术后前庭进入血液对膜迷路的影响,总之为了了解术后中耳和内耳组织反应,为临床上施行此种手术后所表现的征象找出病理、生理上的依据及其预防措施。
Preface Tarsus floor excision is not only the first choice for the treatment of deafness of otosclerosis, but also has a wide range of applications. For example, middle ear deformities, tympanosclerosis, and inflammation of some chronic suppurative otitis media have been eliminated in combination with ossicular chain fixation Hearing patients can use this technique.
