A new era has arrived in auditory rehabilitation with the introduction of new technologies such as electroacoustic stimulation (EAS). EAS is indicated for patients with residual hearing at low frequencies and severe or profound hearing loss at high frequencies. These patients have no indication for conventional cochlear implant and have difficulties in adapting to individual sound amplification devices. Preservation of hearing is vital in this process; the surgical technique must be based on this concept.
To present the cochlear implant surgical technique with MED-EL Mand FlexEAS to preserve hearing in patients with hearing loss at high frequencies and to maintain low frequency hearing. We are the first institution to carry out this treatment in Brazil.
A case report of the surgical technique carried out in four patients; the procedure was carried out by the cochlear implant group of a specialized clinical hospital.
The procedures were successful and uneventful.
We described the technique used at our institution for implants using EAS; the surgical technique is complex and includes steps for preservation of hearing.
摘要：随着电声刺激（EAS）等新技术的引入，听觉康复已经进入了一个新时代。EAS 适用于低频残余听力和高频重度或极重度听力损失的患者。这些患者不适合常规的人工耳蜗植入，并且在适应个人声音放大设备方面存在困难。在这个过程中，听力保护至关重要；手术技术必须基于这一理念。
目的：介绍 MED-EL Mand FlexEAS 人工耳蜗植入手术技术，以保留高频听力损失患者的听力并维持低频听力。我们是巴西第一家开展这种治疗的机构。
方法：报告了 4 名患者的手术技术情况；该程序由专门的临床医院的人工耳蜗植入小组进行。
结果：手术过程顺利，无并发症。
结论：我们描述了我们机构使用 EAS 进行植入的技术；手术技术复杂，包括听力保护步骤。
