To explore the safety and efficacy of cochlear implantation among elderly patients with severe to profound hearing loss.
Eight pre-elderly and elderly patients with an medium age of 58 years who suffered from bilateral severe to profound sensorineural hearing loss received cochlear implantation between November 2008 and November 2009. The patients' tolerance to implant surgery and the occurrence of complications were observed. Three months after switch-on, aided threshold and speech performance were measured.
The surgery was uneventful in all cases with normal intraoperative neural response telemetry elicited. Three months after switch-on, average aided threshold across speech frequencies was 35 - 50 dB HL measured in sound field with warble tone. The results of speech audiometry showed large variation between individuals. Some patients achieved good performance in monosyllable recognition test, disyllables threshold test and sentences recognition test under both bubble noise and quiet conditions.
Pre-elderly and elderly patients can endure a state of general anesthesia for cochlear surgery without complications. Cochlear implant can provide reconstruction of speech recognition capabilities for elderly patients suffering from severe to profound hearing loss. Cochlear implantation can improve the quality of life of elderly patients with hearing loss.
探讨老年重度至极重度听力损失患者人工耳蜗植入的安全性和有效性。
2008年11月至2009年11月，8例平均年龄58岁的老年及准老年双侧重度至极重度感音神经性听力损失患者接受了人工耳蜗植入。观察患者对植入手术的耐受性及并发症发生情况。开机3个月后，测量助听阈值和言语表现。
所有病例手术均顺利，术中神经反应遥测正常。开机3个月后，在声场中用啭音测量的言语频率平均助听阈值为35 - 50 dB HL。言语测听结果显示个体间差异较大。部分患者在气泡噪声和安静条件下的单音节识别测试、双音节阈值测试和句子识别测试中表现良好。
老年及准老年患者能够耐受人工耳蜗手术的全身麻醉状态且无并发症。人工耳蜗可为老年重度至极重度听力损失患者提供言语识别能力重建。人工耳蜗植入可提高老年听力损失患者的生活质量。
