To assess the annual incidence of vestibular neuritis (VN) in the Japanese population.
We conducted a mail-based survey targeting otolaryngologic clinics and hospitals across Japan to estimate the annual number of patients who were newly-diagnosed with VN during the one-year period of 2021. Using a stratified sampling method, we selected 1,107 departments and asked them to report the number of new patients with VN and their demographics. The total number of VN patients was estimated by multiplying the reported numbers by the reciprocal of the sampling rate and response rate.
The overall survey response rate was 40.5 % (448 departments). The estimated number of newly-diagnosed VN patients in 2021 was 8,861 (95 % confidential interval [CI], 2,290-15,432) The annual incidence of VN was 7.05 per 100,000 population in Japan. The male-to-female ratio of VN patients was 0.96, and the mean age was 60.3 ± 16.1 years (range 11-94 years).
The annual incidence of VN in Japan in 2021 had almost doubled and the mean age had become older compared to the previous study in 1993 (annual incidence; 3.5 per 100,000 per year; mean age: 45 years).
评估日本人群中前庭神经炎 (VN) 的年发病率。
我们对日本各地的耳鼻喉科诊所和医院进行了一项基于邮件的调查，以估计在 2021 年的一年期间新诊断为 VN 的患者人数。我们使用分层抽样方法，选择了 1107 个科室，并要求他们报告新 VN 患者的人数及其人口统计学信息。通过将报告的数量乘以抽样率和响应率的倒数来估计 VN 患者的总数。
总体调查响应率为 40.5%（448 个科室）。2021 年新诊断 VN 患者的估计人数为 8861 人（95%置信区间 [CI]，2290-15432）。日本 VN 的年发病率为每 100000 人 7.05 例。VN 患者的男女比例为 0.96，平均年龄为 60.3±16.1 岁（范围 11-94 岁）。
与 1993 年的先前研究相比，2021 年日本 VN 的年发病率几乎翻了一番，平均年龄也有所增加（年发病率；每年每 100000 人 3.5 例；平均年龄：45 岁）。
