CONCLUSION. The recurrence rate of vertigo due to any cause in patients with vestibular neuritis (VN) was about 26.0% in our study. No clinical characteristics were significantly associated with recurrences.
We aimed to: 1) determine the prevalence of recurrent VN; 2) compare the clinical characteristics and epidemiologic factors of patients with non-recurrent and recurrent VN; and 3) determine the prevalence of benign paroxysmal positional vertigo (BPPV) in patients with VN.
In 131 patients diagnosed as having VN (68 males, aged 49.8 ± 14.9 years and 63 females, aged 57.5 ± 12.5 years), a retrospective chart review and telephone survey about the recurrent vertigo were performed. Vestibular function testing, inner ear magnetic resonance imaging (MRI), and pure tone audiograms were performed on every patient. Vestibular function testing was repeated in patients with recurrences.
Fourteen of 131 patients (10.7%) had recurrent VN. The subjective intensity of recurrent VN was less than the first attack. There were no significant differences in clinical characteristics such as accompanying headache or preceding respiratory infection and in epidemiologic risk factors between patients with recurrent and non-recurrent VN. Twenty of 131 patients (15.3%) experienced BPPV during the follow-up period.
结论。在我们的研究中，前庭神经炎（VN）患者因任何原因导致的眩晕复发率约为26.0%。没有临床特征与复发显著相关。
我们旨在：1）确定复发性VN的患病率；2）比较非复发性和复发性VN患者的临床特征和流行病学因素；3）确定VN患者中良性阵发性位置性眩晕（BPPV）的患病率。
对131例诊断为VN的患者（68例男性，年龄49.8±14.9岁；63例女性，年龄57.5±12.5岁）进行回顾性病历审查和关于复发性眩晕的电话调查。对每位患者进行前庭功能测试、内耳磁共振成像（MRI）和纯音听力图检查。对复发患者重复进行前庭功能测试。
131例患者中有14例（10.7%）出现复发性VN。复发性VN的主观强度低于首次发作。复发性和非复发性VN患者在伴随头痛或先前呼吸道感染等临床特征以及流行病学危险因素方面没有显著差异。131例患者中有20例（15.3%）在随访期间出现BPPV。
