We describe a male patient who presented a progressive conductive unilateral hearing loss 20 years after otosclerosis surgery. Computed tomography (CT) scan and magnetic resonance imaging (MRI) findings suggested a facial schwannoma in its tympanic segment. At the time of revision surgery, a facial schwannoma was found to originate at the tympanic segment, pushing the prosthesis out of the oval window fenestration. The Teflon-piston was repositioned with difficulties in the central platinotomy, and the facial schwannoma was left intact.
我们描述了一名男性患者，他在耳硬化症手术后20年出现进行性单侧传导性听力损失。计算机断层扫描（CT）和磁共振成像（MRI）结果提示鼓室段存在面神经鞘瘤。在翻修手术时，发现面神经鞘瘤起源于鼓室段，将人工听骨假体推出卵圆窗开窗处。特氟龙活塞在中央铂质切开术中重新定位困难，面神经鞘瘤未予处理。
