报告64例慢性化脓性中耳炎听骨受损方式,在胆脂瘤性中耳炎,如为鼓膜松弛部穿孔,听骨破坏一般从听骨链外侧开始,锤骨头最先受损,其次是砧骨短脚,镫骨多完好;而鼓膜紧张部穿孔时,听骨破坏从砧骨内侧面开始,砧骨长脚最先受损,砧镫关节易受累。在慢性单纯性化脓性中耳炎,听骨受损频度低,病变轻,病变多始于砧骨长脚尖端部。文中还讨论了听骨破坏方式对选择中耳手术术式中的意义。
Report of 64 cases of chronic otitis media with ossification of the bone in the risk of cholesteatoma otitis media, such as tympanic membrane perforation, ossicular damage generally occurs from the outside of the ossicular chain, the first bone hammer damage, followed by the incus short The foot and tarsal bone were all intact. When the tympanic membrane was punctured, the destruction of the sternum began from the medial aspect of the incus, and the ankle long leg was the first to be damaged. The anvils and joints were easily affected. In chronic simple purulent otitis media, the frequency of ossification of the ossicles is low, and the lesions are mild. The lesions mostly begin at the tip of the incus. The article also discusses the meaning of the mode of ossification of the ossicles in the selection of middle ear surgery.
