The recording of auditory brain stem potentials evoked by electrical stimulation of the cochlea is a part of our assessment protocol before pediatric cochlear implantation. It constitutes an objective and reproducible method to estimate the stimulability of the auditory system for candidates to cochlear implant. Ten children, aged from 3 to 12 years, with deep deafness of the 2nd and 3rd group with no response to ABR, undergone electric stimulation of the cochlea. All patients were anesthetized and paralyzed. Electric pulses are delivered by a cochlear stimulator, through a transtympanic needle electrode, placed in the promontory. We record responses on a Medelec "Saphire" computer. One of the main problem we try to solve is the stimulus artefact which occurs during the first ms. The other one is to be sure that the recorded responses are corresponding to the neural activity of the auditory nerve and the brainstem auditory pathway.
通过电刺激耳蜗诱发听觉脑干电位的记录是我们小儿人工耳蜗植入术前评估方案的一部分。它构成了一种客观且可重复的方法，用于评估人工耳蜗植入候选人听觉系统的可刺激能力。10名年龄在3至12岁之间、属于重度聋的第二和第三组且听性脑干反应无反应的儿童接受了耳蜗电刺激。所有患者均接受麻醉并被麻痹。电脉冲由耳蜗刺激器通过置于岬部的经鼓膜针电极传递。我们在Medelec“Saphire”计算机上记录反应。我们试图解决的主要问题之一是最初几毫秒内出现的刺激伪迹。另一个问题是要确保记录的反应与听神经和脑干听觉通路的神经活动相对应。
