Abstract

Objective: To assess the prevalence and annual incidence of bilateral vestibulopathy (BV) diagnosed in the Japanese adult population. Methods: We conducted a mail-based survey targeting otolaryngologic clinics and hospitals across Japan to estimate the annual number of patients who were diagnosed as having bilateral vestibulopathy after vestibular function tests during a 12-month period ending March 2019. Using a stratified sampling method, we selected 1,106 departments and asked them to report the number of patients with BV and their demographics. The total number of patients was estimated by multiplying the reported numbers by the reciprocal of the sampling rate and response rate. Results: The overall survey response rate was 51.4% (568 departments). The estimated number of patients diagnoses with BV in 2018 was 1,063 (95% confidential interval [CI], 127-1,998) which included 407 patients (95% CI: 134-680) newly-diagnosed with BV. The prevalence and annual incidence of BV in Japan were 0.84 and 0.32, respectively per 100,000 population in Japan. The male-to-female ratio of BV patients was 1.29, and the mean age was 63.7 ± 16.4 years (range 18-84 years). The most frequent etiologies of BV were Meniere's disease (11.4%), meningitis (3.4%), and ototoxic agents (3%). Conclusions: Patients who were diagnosed as having BV were extremely rare in Japan.
