The records of 203 stapedectomy operations in which we used a prosthesis from the malleus handle or a columella from the tympanic membrane were reviewed; 63 operations were primary stapedectomies, and 85% had a postoperative conductive deficit of 15 dB or less. The most common single indication for an incus bypass procedure was idiopathic malleus head fixation. Sixty-six operations were revision stapedectomies; 65% had a postoperative deficit of 15 dB or less. In 50% the bypass indication was necrosis of the incus. There were 74 stapedectomies in a previously fenestrated ear; 60% had a postoperative deficit of 15 dB or less. Incus bypass procedures in stapedectomy, when indicated, yield satisfactory hearing results. Otolaryngologists who perform stapedectomy must be familiar with these procedures.
我们回顾了203例镫骨切除术的记录，这些手术中我们使用了来自锤骨柄的假体或来自鼓膜的柱状体；63例手术为初次镫骨切除术，85%的患者术后传导性听力损失为15dB或更低。砧骨旁路手术最常见的单一指征是特发性锤骨头固定。66例手术为翻修镫骨切除术；65%的患者术后听力损失为15dB或更低。在50%的病例中，旁路手术的指征是砧骨坏死。在先前已开窗的耳中进行了74例镫骨切除术；60%的患者术后听力损失为15dB或更低。镫骨切除术中的砧骨旁路手术，在有指征时，能产生令人满意的听力结果。进行镫骨切除术的耳鼻喉科医生必须熟悉这些手术。
