The profoundly deaf, who gain little or no benefit from conventional hearing aids and meet various criteria are potential candidates for cochlear implantation. The last two decades have witnessed remarkable progress in this field, and it is now a routine clinical procedure. A few adult patients who are potential candidates for cochlear implantation have an unacceptably high risk for hypotensive general anaesthesia due to other systemic conditions. This group has been successfully implanted under local anaesthesia in our centre. The post-implantation progress of these patients was comparable to those carried out under hypotensive general anaesthesia. Data regarding patient selection criteria, examination, anaesthesia, surgery and the outcome are discussed. It was concluded that cochlear implantation under local anaesthesia is a safe and effective procedure for those patients who otherwise may be denied an implant.
对于传统助听器获益甚微或毫无益处且符合各种标准的极重度聋患者，是人工耳蜗植入的潜在候选者。在过去二十年里，该领域取得了显著进展，如今它已是一种常规临床手术。一些有人工耳蜗植入潜在可能的成年患者，由于其他全身状况，接受降压全身麻醉的风险高得令人难以接受。在我们中心，这组患者已成功在局部麻醉下完成植入。这些患者植入后的进展与在降压全身麻醉下进行植入的患者相当。本文讨论了关于患者选择标准、检查、麻醉、手术及结果的数据。得出的结论是，对于那些否则可能无法接受植入的患者，局部麻醉下的人工耳蜗植入是一种安全有效的手术。
