结论：在内耳畸形病例中，EABR 是客观确认装置功能和外周听觉神经元直至脑干水平的植入反应性的可靠且有效的方法。目的：探讨在人工耳蜗植入过程中测量术中电诱发复合动作电位（ECAP）和电诱发听性脑干反应（EABR）对于先天性内耳异常和非先天性内耳异常患者的有用性。方法：连续 38 名 5 岁或以下患有先天性重度听力损失的儿童（40 只耳朵）。二十四（25 只耳朵）没有先天性内耳异常。 14例（15耳）畸形患者有共同空洞（4耳）、不完全分隔I型（3耳）、耳蜗发育不全III型（3耳）、前庭导水管扩大（4耳）、耳蜗神经管狭窄（1耳）。主要成果衡量指标是 ECAP 和 EABR 应对措施。结果：在没有任何畸形的 25 只耳朵中，分别有 21 只、3 只和 1 只显示“良好”、“可变”和“无”ECAP 反应，分别有 24 只和 1 只显示“良好”和“可变”耳蜗内反应。在 15 只畸形耳朵中，两只显示“良好”ECAP 反应，九只显示“可变”ECAP 反应，四只显示“无”ECAP 反应。此外，5 个显示“良好”的 EABR 响应，10 个显示“可变”的 EABR 响应。
Conclusions: EABR is a reliable and effective way of objectively confirming device function and implant-responsiveness of the peripheral auditory neurons up to the level of the brainstem in cases of inner ear malformation. Objective: To investigate the usefulness of measuring the intra-operative electrically evoked compound action potential (ECAP) and electrically evoked auditory brainstem response (EABR) in patients with and without congenital inner ear anomalies during cochlear implantation. Method: Thirty-eight consecutive children (40 ears) aged 5 or younger with congenital profound hearing loss. Twenty-four (25 ears) lacked congenital inner ear anomalies. The 14 patients (15 ears) with a malformation had common cavities (four ears), incomplete partition type I (three ears), cochlea hypoplasia type III (three ears), enlarged vestibular aqueduct (four ears), and cochlear nerve canal stenosis (one ear). Main outcome measures are ECAP and EABR responses. Results: Of the 25 ears lacking any malformation, 21, three, and one showed 'Good', 'Variable', and 'No' ECAP responses, respectively, and 24 and one showed 'Good' and 'Variable' intra-cochlear responses, respectively. Of the 15 ears with a malformation, two showed 'Good' ECAP responses, nine had 'Variable' ECAP responses, and four showed 'No' ECAP responses. Moreover, five showed 'Good' EABR responses and 10 showed 'Variable' EABR responses.
