A woman with a long history of chronic otitis media had a stapedectomy after a surgical diagnosis of otosclerosis. In the histologic study of the temporal bones, done after her death four years later, the main portion of the stapes footplate was present but fractured and no otosclerosis was present. New celluluar bone which simulated otosclerosis filled the anterior oval window niche and was continuous with the middle ear surface of the footplate fragments. The new bone extended anteriorly to overlie a tympanosclerotic focus and inferiorly was continuous with the periosteum of the middle ear. At least part of the new bone formation occurred after stapedectomy. This may explain the poor long-term results frequently encountered when a stapedectomy is done on patients with tympanosclerotic fixation of the stapes footplate.
一名有慢性中耳炎长期病史的女性，在手术诊断为耳硬化症后接受了镫骨切除术。四年后她去世，对颞骨进行组织学研究时发现，镫骨足板的主要部分存在但已骨折，且未发现耳硬化症。模拟耳硬化症的新细胞性骨填充了前椭圆窗龛，并与足板碎片的中耳表面相连。新骨向前延伸覆盖鼓膜硬化灶，向下与中耳骨膜相连。至少部分新骨形成发生在镫骨切除术后。这可能解释了在对镫骨足板鼓膜硬化固定的患者进行镫骨切除术时经常遇到的长期效果不佳的情况。
