作者从1976年至1982年行半砧骨植入的听骨重建术85例。除9例失访外对其余76例进行随访研究。共分二组:第一组为19例鼓膜完整无活动病灶者,第二组为57例慢性化脓性中耳炎伴或不伴发胆脂瘤或为改良乳突根治术腔。对第二组患者在完全清除胆脂瘤后才考虑行听骨重建术。随访时间6月至6年。评价气骨导差方法根据500,1000和2000Hz的平均听阈和语言接受阈。根据有无病变而选择耳后或耳内切口。切除不可逆病灶后检查听骨链,根据圆窗反射判断镫骨活动度,同时检查槌骨是否可用以重建听骨链。当砧骨有
From 1976 to 1982, the authors performed 85 cases of hemi-implants under half anvil incision. The remaining 76 patients were followed up except for 9 missed visits. Divided into two groups: the first group of 19 patients with intact tympanic membrane lesions, the second group of 57 cases of chronic suppurative otitis media with or without cholesteatoma or modified mastoid cavity. The second group of patients after complete removal of cholesteatoma only consider the line of bone reconstruction. Follow-up time from June to 6 years. The evaluation of the air-bone conduction method was based on average hearing thresholds and language acceptance thresholds of 500, 1000 and 2000 Hz. According to the presence or absence of lesions and choose ear or ear incision. After removal of irreversible lesions examination ossicular chain, according to the reflection of the circular window to determine the degree of stapes activity, and check the hammer can be used to reconstruct the ossicular chain.
