人工耳蜗植入术残余听力保留现状和研究进展

Current status and research progress of residual hearing preservation after cochlear implantation

摘要:

随着手术方法和电极设计等技术的创新，人工耳蜗手术取得了一定的进步，使患者残余听力得到一定的保留。所有手术方法的共同目标即是：保护耳蜗内结构，保留残余听力，以提高听觉言语能力。人工耳蜗术后残余听力的丧失被认为是多种因素的结果，近年来，为获得更好的残余听力保留，人们在电极设计与选择、新型电极涂层、围手术期药物治疗、机器人辅助、图像和电生理引导等方面的研究有了新的突破，对于残余听力的保护有了很大程度的提高。本文将对人工耳蜗术后残余听力保护相关因素的进展作一综述。

Abstract:

With the improvement of surgery methods and the advancement of electrode design and other technological innovations, certain progress has been made in cochlear implant surgery, so that residual hearing can be preserved. The common goal of all surgical methods is to protect the internal structure of the cochlea and retain residual hearing in order to improve auditory speech ability. The loss of residual hearing after cochlear implantation is considered to be the result of many factors. In recent years, in order to obtain better residual hearing preservation, new breakthroughs have been made in the research of electrode design, new electrode coating, perioperative drug therapy, robotic assistance, image guidance, and the protection of residual hearing has been greatly improved. This review will review the progress of factors associated with residual hearing protection after cochlear surgery.
