为了彻底清除病变及改善听力,著者给373例中耳炎患者作了听骨链重建术。手术方法有三种:1.砧骨体移植术:将砧骨体磨一凹陷套在镫骨头上。2.砧骨长脚或短脚移植术:将砧骨长脚或短脚置于锤骨镫骨之间,尽量利用自体砧骨,但已被胆脂瘤侵犯之砧骨最好不用,因为这种砧骨可使鳞状上皮再次植入,遇此情况可采用同种异体砧骨。异体砧骨植入前需浸泡于70％酒精四周以上,高压灭菌消毒。移植方法有两种:将砧骨长脚或短脚置入镫骨前后脚之间,著者认为以长脚为好,在短脚上作一沟状切迹,与锤骨连接比较容易。少数病例因前庭窗龕极度狭窄,可将镫骨前后脚除去,砧骨长脚与活动的镫骨底
In order to completely remove the lesion and improve hearing, the author gave ossicular chain reconstruction in 373 cases of otitis media. There are three surgical methods: 1. Anvil body transplantation: the anvil body grinding a dent set in the bones of the head. 2. The incus long or short foot transplant: the incus long or short feet placed in the malleolar between the tarsus, try to use the autologous incus, but has been the risk of cholesteatoma incus is best not to use because This kind of incus makes the squamous epithelium re-implant, in which case allograft can be used. Allograft incus should be soaked in 70% alcohol for more than four weeks before being implanted and autoclaved. There are two methods of transplantation: the incus long or short feet into the stapes between the anterior and posterior legs, the authors believe that the long legs as well, make a groove-shaped notch on the short legs, and the malleus is relatively easy to connect. A small number of cases due to extreme narrow vestibular window niches, ankle bones can be removed before and after the foot, the incus foot and the active tarsal base
