讲方言成人语后聋患者REZ-Ⅰ型人工耳蜗植入后疗效分析

Clinical effectiveness of REZ-Ⅰ cochlear implants in post-lingual deafened Chinese dialect speakers

目的:观察REZ-Ⅰ型人工耳蜗植入(CI)成人语后聋患者后听力改善情况,分析其对部分讲方言患者的临床效果。方法:将48例成人语后聋CI患者按所讲语言分为普通话组(41例)和方言组(7例),分别进行CI术后90d的声场测试和听觉能力测评,根据临床疗效判定标准对2组受试者进行临床疗效评估,并对疗效观察指标进行统计学分析。结果:2组REZ-Ⅰ型CI患者经过术后定期康复训练,在开机后90d的总有效率均为100%,且疗效观察指标经χ2检验差异无统计学意义。结论:REZ-Ⅰ型国产人工耳蜗对部分讲方言的重度、极重度成人语后聋患者疗效确切,与讲普通话的植入患者疗效相当。

objective： To investigate the improvement of severe-to-profound hearing-impaired adults received REZ-Ⅰ cochlear implant and to give an analysis to some Chinese dialect speakers.Method： With standard assessment table and standard testing program,48 post-lingual hearing-impaired adults were divided into Mandarin language group（41 cases） and dialect group（7 cases）.All of them were tested and scored for their hearing and speech perception abilities after 90 days rehabilitation.Sound field audio-metries were performed at the same time.Clinical effectiveness of each subject in the two groups were assessed according to criteria,and efficacy index were statistically analyzed.Result：The total effective rates were 100% in both groups after 90 days hearing and speech perception rehabilitation.The clinical effectiveness were equal and there was no statistic significant differences between the groups.Conclusion：REZ-Ⅰ cochlear implantation has similar effect for Chinese dialect spoken adults compared to mandarin spoken adults with post-lingual severe-to-profound hearing loss via appropriate postoperative rehabilitation.
