Abstract

ObjectiveTo evaluate outcomes of cochlear implantation (CI) in patients with unilateral sensorineural hearing loss (USNHL) and explore effects and stimulation current in USNHL patients with bony cochlear nerve canal (BCNC) stenosis versus normal cochlear nerve canals.MethodsA prospective study was conducted on 23 USNHL patients who underwent CI (MED-EL) from May 2019 to March 2023. Preoperative CT and MRI scans were performed to measure BCNC width. Subjects were divided into BCNC stenosis (BCNC-S) and BCNC normal (BCNC-N) groups. Hearing thresholds, speech recognition scores (SRS), sound localization ability, and auditory/musical abilities were assessed before and two years after CI. Differences were determined using Stata statistical software, with significance defined as p < .05.ResultsEleven patients were diagnosed with BCNC stenosis. CI significantly improved SRS under noisy conditions (p = .027) and sound localization ability (p < .05), as well as auditory and musical quality (p < .05). No significant differences in outcomes were found between BCNC-S and BCNC-N groups. BCNC-S group had higher stimulation current than BCNC-N group.ConclusionsCI provides similar improvements for USNHL patients with or without BCNC stenosis.SignificanceThe findings will contribute to the understanding of cochlear implant outcomes in patients with USNHL and BCNC stenosis.

伴有或不伴有骨性耳蜗神经管狭窄的单侧感音神经性听力损失患者人工耳蜗植入术的效果。

目的评价单侧感音神经性听力损失（USNHL）患者人工耳蜗植入术（CI）的效果，探讨伴有骨性耳蜗神经管（BCNC）狭窄的USNHL患者与正常耳蜗神经管的对比效果及刺激电流。方法对2019年5月至2023年3月接受CI （MED-EL）治疗的23例USNHL患者进行前瞻性研究。术前行CT和MRI扫描测量BCNC宽度。将受试者分为BCNC狭窄组（BCNC- s）和BCNC正常组（BCNC- n）。听力阈值、语音识别评分（SRS）、声音定位能力和听觉/音乐能力分别在CI前和CI后两年进行评估。采用Stata统计软件测定差异，显著性定义为p p =。027)和声音定位能力(p p
