To restore auditory sensation for patient suffering loss of hearing due to bilateral acoustic neuromas.
One patient of bilateral acoustic neuromas received auditory brainstem implant (ABI) at the same surgery for resection of the second tumor. The retrosigmoid approach was used for resection of the tumor and to exposure the lateral recess of the fourth ventricle for placement of ABI electrode array. Intraoperative 7th and 9th nerves monitoring and electrically evoked auditory brainstem responses (EABR) were recorded to localize the placement of ABI electrode array.
Initial ABI switch-on was performed eight weeks after the surgery under close monitoring of vital signs. Auditory sensation was perceived on stimulation of all channels.
The multichannel ABI could effectively restore auditory sensation for patient deafened by bilateral acoustic neuromas. The accurate location of the cochlear complex during surgery was the critical factor for success of ABI.
为因双侧听神经瘤导致听力丧失的患者恢复听觉。
一名双侧听神经瘤患者在切除第二个肿瘤的同一手术中接受了听觉脑干植入（ABI）。采用乙状窦后入路切除肿瘤并暴露第四脑室侧隐窝以放置ABI电极阵列。术中记录第7和第9神经监测以及电诱发听觉脑干反应（EABR）以定位ABI电极阵列的放置位置。
术后八周在密切监测生命体征的情况下首次开启ABI。刺激所有通道时均能感知到听觉。
多通道ABI可有效为因双侧听神经瘤致聋的患者恢复听觉。手术过程中蜗复合体的准确定位是ABI成功的关键因素。
