The purpose of this study was analyzing the characteristic of the electrically evoked auditory brainstem responses (EABR) of cochlear implantation (CI) patients with absence of cochlear modiolus (ACM) and comparing the EABR results in deaf patients with normal anatomic structures. Also we assessed the auditory rehabilitation of ACM patients after cochlear implantation.Twenty-eight profoundly deaf patients were contained, 14 of them were ACM (group A) and the rest were normal anatomic structures (group B). They all received Austria cochlear implants from 2004 to 2015. Postoperative EABR were measured and recorded with No. 2, 6, 11 electrodes in patients receving cochlear implantation. The lead-out rate and threshold of EABR between groups were compared and analyzed. The lead-out rates of EABR in group A was 71.4% and group B was 100%. The thresholds of EABR in group A were higher than group B (< 0.05). In group A, there were no statistical difference in the thresholds of EABR among electrodes No.2,6 and 11. However, in group B, there were statistical difference in the thresholds of EABR between electrodes No.2 and 11 (< 0.05), and the thresholds of No.2 was lower than No.11EABR could be used in assessing the objective auditory rehabilitation in ACM patients after cochlear implantation.
本研究旨在分析耳蜗植入（CI）患者中无蜗轴（ACM）者的电诱发听性脑干反应（EABR）特征，并将其与解剖结构正常的聋患者的EABR结果进行比较。此外，我们评估了ACM患者耳蜗植入后的听觉康复情况。纳入28例极重度聋患者，其中14例为ACM患者（A组），其余为解剖结构正常者（B组）。他们均在2004年至2015年期间接受了奥地利耳蜗植入。对接受耳蜗植入的患者用2号、6号、11号电极测量并记录术后EABR。比较并分析两组间EABR的引出率和阈值。A组EABR引出率为71.4%，B组为100%。A组EABR阈值高于B组（<0.05）。在A组中，2号、6号和11号电极间EABR阈值无统计学差异。然而，在B组中，2号和11号电极间EABR阈值有统计学差异（<0.05），且2号电极阈值低于11号。EABR可用于评估ACM患者耳蜗植入后的客观听觉康复情况。
