Sensorineural hearing loss may occur following stapes surgery. The reason for this remains unclear in spite of experimental studies in animals and postmortem temporal bone evaluations in humans. In this study, we quantitatively evaluated the sensorineural elements of six human temporal bones after stapes surgery. Outer hair cell loss in the upper basal turn was present in two cases. This lesion has not previously been described in human temporal bones after stapes surgery. In temporal bones with preoperative sensorineural hearing loss, evidence of presbycusis was also present. The importance of quantification in evaluating these structures must be stressed.
镫骨手术后可能会发生感音神经性听力损失。尽管在动物身上进行了实验研究，并对人类颞骨进行了尸检评估，但原因仍不清楚。在本研究中，我们对六例镫骨手术后的人类颞骨的感音神经成分进行了定量评估。两例患者上基底转出现外毛细胞缺失。这种病变以前在镫骨手术后的人类颞骨中未曾描述过。在术前有感音神经性听力损失的颞骨中，也存在老年性聋的证据。必须强调量化在评估这些结构中的重要性。
