正常聽力耳鳴者之耳石功能障礙

// Otolithic Dysfunction in Normal-Hearing Individuals With Tinnitus

本研究針對正常聽力且單側耳鳴者，評估前庭系統反射功能，包括頸肌、眼肌及咬肌的前庭誘發肌電位（VEMPs）｜結果顯示耳鳴側VEMP振幅明顯降低，雙耳非對稱性增加，且耳鳴時間越長，前庭周邊功能退化越嚴重｜研究指出耳鳴常伴隨前庭異常，VEMPs具臨床潛力作為檢測生物標記。

// This study investigated vestibular involvement in normal-hearing individuals with unilateral tinnitus by assessing sacculo-collic, utriculo-ocular, and vestibulo-masseteric reflexes using cervical, ocular, and masseter vestibular evoked myogenic potentials (VEMPs). Results showed significantly reduced VEMP amplitudes and increased interaural asymmetry in tinnitus ears compared to non-tinnitus ears and controls, while latencies remained unchanged. Longer tinnitus duration correlated with greater peripheral vestibular deterioration. The findings suggest vestibular abnormalities coexist with tinnitus, and VEMPs may serve as clinical biomarkers for detecting these abnormalities.
