Abstract (English): Background: Despite the growing use of cervical (cVEMP) and ocular (oVEMP) VEMP tests, their effectiveness in predicting chronic dizziness in vestibular neuritis (VN) patients remains unclear. Our research examines the link between long-lasting dizziness and inner ear assessments, encompassing VEMPs induced by air-conducted sound (ACS), bone-conducted vibration (BCV), and galvanic vestibular stimulation (GVS). Objectives: This study explores prognostic markers by examining the relationship between the persistence of dizziness symptoms and various inner ear test findings in VN patients. Material and methods: A retrospective cohort of 60 unilateral VN patients underwent comprehensive audiovestibular tests, including pure tone audiometry, cVEMP and oVEMP induced by ACS, BCV, GVS, and caloric tests. Patient subgroups were established based on dizziness duration: short-term (<3 months) and long-term (≥3 months). Results: No substantial correlation existed between the dizziness duration and the outcomes of any particular single inner ear test. However, patients exhibiting concurrent abnormal GVS-cVEMP and GVS-oVEMP were more likely to experience prolonged dizziness, indicating more extensive vestibular system involvement. Conclusions: Concurrent abnormalities in GVS-cVEMP and GVS-oVEMP may indicate a higher chance of long-term dizziness in VN. Significance: This study identifies concurrent abnormalities in GVS-cVEMP and GVS-VEMP as a potential prognostic marker for prolonged dizziness in VN. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 尽管颈部(cVEMP)和眼部(oVEMP)VEMP 测试的使用越来越广泛, 但它们在预测前庭神经炎 (VN) 患者慢性头晕方面的有效性仍不清楚。本研究考察长期头晕与内耳评估之间的联系, 这些评估包括由气导声音 (ACS)、骨导振动 (BCV) 和电前庭刺激 (GVS) 引起的 VEMP 。 本研究通过检查 VN 患者头晕症状的持续性与各种内耳测试结果之间的关系来探索预后指标。 回顾性队列中的 60 名单侧 VN 患者接受了全面的听觉前庭测试, 包括纯音测听、由 ACS、BCV、GVS 引起的 cVEMP 和 oVEMP以及热量测试。根据头晕持续时间将患者分为短期(<3 个月)和长期(≥3 个月)两组。 头晕持续时间与任何单个内耳测试结果之间没有显著相关性。然而, 同时出现 GVS-cVEMP 和 GVS-oVEMP 异常的患者更有可能出现长期头晕, 表明前庭系统受累范围更广。 GVS-cVEMP 和 GVS-oVEMP 同时出现异常可能表明 VN 患者发生长期头晕的可能性更高。 本研究将 GVS-cVEMP 和 GVS-VEMP 同时异常界定为 VN 患者长期头晕的潜在预后指标。 [ABSTRACT FROM AUTHOR]
