| Sumario: | Background: The characteristics of auditory processing and reorganization after unilateral deafness remain unclear. Aims/Objectives: This study aimed to examine subcortical and cortical auditory neurophysiological features in young adults with unilateral deafness according to the side of deafness. Methods: Patient group: A total of 27 men (25.93- ± 3.64-year old) with unilateral deafness [15 right-sided and 12 left-sided deafness (L-SD)] were included. Twenty-one adult males (29.90 ± 3.05 years) with normal bilateral hearing were included in the Normal Control group. Neurodiagnostic Auditory Brainstem Responses (ABR) and Cortical Auditory Evoked Potentials (CAEP) tests were performed on all participants. ABR and CAEP results were compared between groups. Results: In the right-sided deafness (R-SD) group, ABR wave V amplitudes (left ear) were higher than the control group, and the III–V interpeak latencies were found to be shorter (p =.007, p =.032, respectively). In the L-SD group: CAEP wave P1N1 and N1P2 amplitudes were higher than in the R-SD group (p =.037, p =.015, respectively). Conclusions and Significance: Auditory neurophysiological biomarkers in adults with unilateral deafness differ according to the side of the deafness. The results of this study may provide preliminary information for the development of appropriate rehabilitation methods according to the deafness side after single-sided deafness. 单侧失聪后的听觉处理和重组特征尚不清楚。 本研究旨在检查单侧失聪青年的失聪侧皮层下和皮层听觉神经生理学特征。 患者组: 共纳入 27 名单侧失聪男性(25.93-±3.64 岁)[15 名右侧失聪和 12 名左侧失聪(L-SD)]。正常对照组包括 21 名双侧听力正常的成年男性(29.90 ± 3.05 岁)。所有参与者均进行了神经诊断听觉脑干反应 (ABR) 和皮层听觉诱发电位 (CAEP) 测试。比较了各组的 ABR 和 CAEP 结果。 右侧失聪(R-SD)组 ABR 波 V 振幅(左耳)高于对照组, III-V 峰间潜伏期较短(分别为 p=.007、p=.032)。L-SD 组: CAEP 波 P1N1 和 N1P2 振幅高于 R-SD 组(分别为 p=.037、p=.015)。 单侧失聪成人的听觉神经生理生物标志物因失聪侧而异。本研究结果可为单侧失聪后根据失聪侧制定适当的康复方法提供初步信息。 |
