It is commonly accepted that the intracochlear placement of the cochlear implant electrode is potentially damaging to the hearing rests which may exist. Consequently, cochlear implants have been recommended for totally deaf ears only. The question has been raised whether or not it is possible to preserve residual hearing during intracochlear implantation through extremely careful surgical techniques. Experience has shown, that the cochleotomy of the scala tympani anterior to the round window niche, careful preservation of the fibrine endost layer and the use of Healon are amongst the surgical procedures described which may assist in retaining the rest function of the inner ear. These observations which are discussed in detail suggest that the experienced surgeon can effect preservation of residual hearing for patients who cannot derive significant benefits from conventional acoustic amplifiers.
人们普遍认为，人工耳蜗电极植入耳蜗内部可能会对可能存在的残余听力造成损害。因此，人工耳蜗仅被推荐用于全聋的耳朵。有人提出，通过极其精细的手术技术，在耳蜗植入过程中是否有可能保留残余听力。经验表明，圆窗龛前方鼓阶的耳蜗切开术、小心保留纤维内膜层以及使用透明质酸钠等手术操作，有助于保留内耳的残余功能。这些详细讨论的观察结果表明，经验丰富的外科医生能够为那些无法从传统声学放大器中获得显著益处的患者保留残余听力。
