The objective of the present study was to elucidate specific features of etiology and pathophysiology of recurring chronic vestibular dysfunction. It included 90 patients with this pathology of whom 24 (26.6%) presented with vascular compression of the vestibulocochlear nerve diagnosed by means of high-field MRI. This method revealed the high frequency of positionally-dependent vestibular dysfunction associated with neurovascular interactions. Analysis of the state of vestibular dysfunction during the attack-free periods demonstrated the signs of latent vestibular dysfunction in 20 (83.3%) patients. The results of the study provide additional information on the prevalence of vascular compression of the vestibulocochlear nerve in the patients presenting with recurrent chronic dizziness; moreover, they make it possible to evaluate the state of vestibular function and develop the new diagnostic criteria for vestibular paroxismia.
本研究的目的是阐明复发性慢性前庭功能障碍的病因和病理生理学的具体特征。该研究纳入了90例患有这种疾病的患者，其中24例（26.6%）通过高场MRI诊断为前庭蜗神经血管压迫。该方法揭示了与神经血管相互作用相关的位置依赖性前庭功能障碍的高发生率。对无发作期前庭功能障碍状态的分析表明，20例（83.3%）患者存在潜在前庭功能障碍的迹象。该研究结果提供了有关复发性慢性头晕患者前庭蜗神经血管压迫患病率的更多信息；此外，它们使得评估前庭功能状态和制定前庭阵发症的新诊断标准成为可能。
