影响人工耳蜗置入后听力改善的因素

目的：如何解释和预测人工耳蜗存在的较大个体差异，从而预测置入后康复效果，不仅倍受听力学者和临床医师的关心，也是置入者及其家属密切关注的问题。通过对接受人工耳蜗置入患者的临床资料及置入后康复情况进行分析与评估，探讨人工耳蜗置入后康复效果的可能影响因素。 方法：28例患者均来源于青岛大学医学院附属医院耳鼻咽喉科，于2002-06/2008-04成功行人工耳蜗置入。分别按年龄、置入后康复训练时间，是否佩戴助听器，术中神经反应遥测技术反应情况、置入前有无残余听力等分组，观察其听觉言语改善情况，对所获结果进行临床分析，观察各因素对听力言语改善情况的影响。 结果：人工耳蜗置入年龄越小听觉言语改善效果越好，残余听力的存在及置入前助听器佩戴对提高置入后听觉言语改善效果有帮助，术中神经反应遥测技术反应良好的患者置入后的听觉言语改善效果也较好，康复训练时间越长效果越好。 结论：人工耳蜗置入后听觉言语改善效果的影响因素包括置入年龄、残余听力、置入前助听器佩戴，术中神经反应遥测技术反应及置入后康复训练时间。

Influential factors of auditory rehabilitation after cochlear implant

OBJECTIVE: How to explain and predict individual difference of artificial cochlea so as to evaluate rehabilitative effect of implant has been paid much attention by audiological scholars, clinical physicians, patients, and their relatives. This study was designed to analyze and evaluate rehabilitative status of patients accepting artificial cochlea implantation to investigate the relative influential factors of auditory rehabilitation. METHODS: A total of 28 patients were selected from Department of Otolaryngology Head and Neck, Affiliated Hospital of Qingdao Medical College from June 2002 to April 2008. They were accessed by age, time of rehabilitation training, usage of hearing aids, audiology and aural image before surgery, and NRT monitoring in cochlear implantation so as to observe auditory improvement. The clinical results were analyzed to detect the effect of various factors on auditory rehabilitation. RESULTS: Age, preoperative preparations and good audiology and aural image are important premises for a successful rehabilitation. Longer the time of using hearing aids and language rehabilitation are, and better results will get. NRT response during operation is also an important factor for good auditory rehabilitation. CONCLUSION: The influential factors of auditory rehabilitation after cochlear implant included the age, audition remains, usage of hearing aids, NRT response during operation, and the time after the cochlear implant operation.
