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.
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.
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 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.
即使由多位不同的外科医生进行手术，在用于电声刺激（EAS）的人工耳蜗植入过程中实现高听力保留率也是有可能的。
本研究旨在通过一项欧洲多中心临床研究，确定采用EAS手术进行听力保留的程度。它还旨在证明EAS对低频残余听力个体在言语感知和主观生活质量测量方面的效果。
在五个参与研究的欧洲中心招募了18例重度高频听力损失患者。基于一套听力学测试以及一份主观助听器受益问卷对受试者进行评估。每位受试者使用带有中等电极的MED-EL C40 +设备尝试进行保留听力的人工耳蜗植入。在引入联合电声模式后长达12个月的规定间隔时间内，评估同侧残余听力和言语辨别能力。
结果显示，15/18例患者有可能实现一定程度的听力保留。随着时间推移，所有受试者在所有三项言语感知测试中均显示出具有统计学意义的益处。这些显著益处也反映在主观受益结果中。
