结论在电声刺激（EAS）人工耳蜗植入术期间，即使由多名不同的外科医生进行手术，也可能实现较高的听力保留率。目标.本研究旨在确定在欧洲多中心临床研究中使用手术治疗EAS的听力保留程度。它还旨在证明EAS在具有残余低频听力的个体中对言语感知和主观生活质量测量的影响。病人和方法。在五个参与的欧洲中心招募了18名患有严重高频听力损失的患者。受试者进行了评估的基础上听力测试电池，以及对主观助听器的好处问卷。每例受试者均尝试使用MED-EL C40+器械（带中号电极）进行听力保留人工耳蜗植入术。残余同侧听力和言语辨别能力进行了评估，在规定的时间间隔长达12个月后，联合电声模式被引入。结果结果表明，在15718例患者中，听力可能得到一定程度的保留。随着时间的推移，所有受试者在所有三项言语感知测试中都表现出统计学显著的益处。这些显著获益也反映在主观获益结局中。
Conclusion. A high rate of hearing preservation during cochlear implantation for electric acoustic stimulation (EAS) is possible, even when surgery is conducted by a number of different surgeons. Objectives. This study aimed to determine the degree of hearing preservation using surgery for EAS in a European multi-centre clinical investigation. It also aimed to demonstrate the effect of EAS in individuals with residual low frequency hearing, both on speech perception and on subjective quality of life measures. Patients and methods. Eighteen patients with profound high frequency hearing loss were recruited in five participating European centres. Subjects were assessed based on an audiologic test battery, as well as on a subjective hearing aid benefit questionnaire. Each subject underwent attempted hearing preservation cochlear implantation using the MED-EL C40+ device with a Medium electrode. Residual ipsilateral hearing and speech discrimination abilities were assessed at defined intervals up to 12 months after the combined electric-acoustic mode was introduced. Results. Results showed that some degree of hearing preservation was possible in 15718 patients. All subjects showed statistically significant benefit on all three speech perception tests over time. These significant benefits were also reflected in the subjective benefit outcomes.
