Abstrakt:	Objectives: Otitis media with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) is a new category of otitis media in which cases of otitis media due to ANCA-associated vasculitis (AAV) are classified, regardless of ANCA variant or ANCA serotype. We aimed to describe the clinical features and course of patients with OMAAV and identify factors associated with hearing outcomes. Methods: We retrospectively analysed 30 patients with OMAAV, classified based on the criteria proposed by the Japan Otological Society in 2016. Results: Single-positive myeloperoxidase-ANCA, single-positive proteinase 3-ANCA, double-positive ANCA, and double-negative ANCA were identified in 47%, 33%, 7%, and 13% of the patients, respectively. All patients subjected to audiometry showed hearing impairments, and 85% were affected bilaterally. Mixed- and sensorineural-type hearing impairments were identified in 80% and 20% of impaired ears, respectively. Hypertrophic pachymeningitis (HPM) was identified in 37% of the patients. Immunosuppressive therapy was administered to 93% of patients, and the median air conduction hearing levels at pre- and post-treatment were 66.1 dB and 43.4 dB, respectively, indicating significant hearing improvements. HPM and a long interval between disease onset and treatment initiation were significantly correlated with poor hearing prognosis. Conclusions: OMAAV develops under any type of ANCA-serology and typically causes mixed or sensorineural bilateral hearing loss. The early initiation of immunosuppressive therapy and the absence of HPM were associated with good hearing outcomes. (© Japan College of Rheumatology 2021. Published by Oxford University Press.
