Auditory Brainstem Implants were developed to partially restore the hearing capabilities of patients without cochlear nerves bilaterally.
this paper aims to discuss the clinical and surgical findings of four ABI patients.
Four patients diagnosed with bilateral schwannomas received auditory brainstem implants (ABI) and had one of their tumors resected in the same surgical procedure. Clinical aspects, surgical technique, anatomic landmarks, and outcomes were analyzed.
the anatomic landmarks were identified in all four patients in relation to the foramina of Luschka. Two patients had CSF leaks. The electrodes were well positioned and hearing sensation was good enough to allow for sound recognition and assist patients perform lip reading.
the outcomes observed in our patients were quite encouraging and offer great perspectives for those suffering from deep bilateral deafness and impaired central auditory pathways.
听觉脑干植入物旨在部分恢复双侧无耳蜗神经患者的听力。
本文旨在探讨4例听觉脑干植入物（ABI）患者的临床及手术结果。
4例诊断为双侧神经鞘瘤的患者接受了听觉脑干植入物（ABI），并在同一次手术中切除了其中一个肿瘤。分析了临床情况、手术技术、解剖标志及结果。
在所有4例患者中均确定了与Luschka孔相关的解剖标志。2例患者发生脑脊液漏。电极位置良好，听觉足够灵敏，能够识别声音并帮助患者进行唇读。
我们患者所观察到的结果相当令人鼓舞，为那些患有双侧重度耳聋及中枢听觉通路受损的患者提供了很好的前景。
