Tympanoplasty can produce a stable hearing improvement in many patients with chronically inflamed ears. In our series of patients, severe damage to the inner ear following surgery occurred in 3% patients and was associated with a hearing loss of greater than 15 dB. Complete hearing loss occurred in 0.2% of the patients reviewed. In patients with an intact ossicular chain, simple myringoplasty is associated with the best results. Loss of the stapedial arches affects the postoperative air-bone gap most significantly, while loss of the manubrium mallei or the creation of a radical mastoid cavity are additional negative factors. Extent or localization of ossicular fixation has no direct influence on hearing results when appropriate ossicular reconstruction is performed.
鼓室成形术可使许多慢性炎症性耳病患者的听力得到稳定改善。在我们的患者系列中，3%的患者术后内耳发生严重损伤，并伴有大于15 dB的听力损失。在所审查的患者中，0.2%出现了完全性听力丧失。在听骨链完整的患者中，单纯鼓膜成形术的效果最佳。镫骨弓缺失对术后气骨导间距的影响最为显著，而锤骨柄缺失或乳突根治术腔的形成是另外的负面因素。当进行适当的听骨重建时，听骨固定的程度或部位对听力结果没有直接影响。
