BACKGROUND/AIMS: The combined electric acoustic stimulation (EAS) of one ear is a topic that has received considerable attention over the last 10 years, the technique having originally been introduced by Prof. Christoph A. von Ilberg for so-called borderline adult cochlear implant (CI) candidates. Its development has followed several parallel strands, including the modification of existing surgical approaches and the use of different CI devices (including new designs of electrode), as well as having been applied to various different groups of patients. The aim of the study described herein was to investigate the application of EAS in children with partial deafness (PD).
In 2002, we performed the first implantation of an adult patient with PD, in which we pioneered the technique of partial deafness cochlear implantation (PDCI). Encouraged by the outstanding results achieved by the application of EAS in adults, we have extended its application to children who have a significant amount of residual hearing in the ear selected for implantation. Between September 2004 and December 2007, 15 children with PD and 10 platinum hearing aid users were implanted with either a COMBI 40+ or a PULSAR, using the 'round window' technique to increase the probability of hearing preservation.
Monosyllabic word recognition increased over a 12-month period in the platinum group, from 31 to 60% under quiet conditions and from 1 to 19% under noisy conditions. In the PDCI group, the commensurate increase was from 34 to 67% under quiet conditions and from 7 to 47% under noisy conditions.
The application of EAS in children gives them the ability to understand speech, hence allowing the child's overall communication skills to be improved by increasing their efficiency and effectiveness.
背景/目的：单耳联合电声刺激（EAS）是过去10年备受关注的一个话题，该技术最初由克里斯托夫·A·冯·伊尔贝格教授引入，用于所谓的临界成年人工耳蜗（CI）候选者。其发展沿着几条平行的路线进行，包括对现有手术方法的改进、使用不同的CI设备（包括电极的新设计），并且已应用于各种不同的患者群体。本文所述研究的目的是调查EAS在部分性耳聋（PD）儿童中的应用。
2002年，我们对一名成年PD患者进行了首次植入，开创了部分性耳聋人工耳蜗植入（PDCI）技术。受EAS在成人中应用取得的出色结果鼓舞，我们将其应用扩展到在选定植入耳中有大量残余听力的儿童。在2004年9月至2007年12月期间，15名PD儿童和10名佩戴铂金助听器的使用者接受了COMBI 40+或PULSAR植入，采用“圆窗”技术以提高听力保留的概率。
在铂金组中，单音节词识别率在12个月期间有所提高，安静条件下从31%提高到60%，嘈杂条件下从1%提高到19%。在PDCI组中，相应的提高分别是安静条件下从34%提高到67%，嘈杂条件下从7%提高到47%。
EAS在儿童中的应用使他们有能力理解言语，从而通过提高效率和有效性来改善儿童的整体沟通技能。
