[Otitis media with antineutrophil cytoplasmic antibody-associated vasculitis]

Objective:To analyze clinical features, diagnosis and treatment of otitis media with antineutrophil cytoplasmic antibody（ANCA） -associated vasculitis（OMAAV）. Methods:This study reported three OMAAV patients and discussed the diagnosis and treatment of OMAAV combined with the recent literature. Results:Two males and one female were included. The age of these three patients ranged from 56 to 72 years. Their characteristics were as follows: ①tympanic membrane with granulation and bloody secretions in two patients; ②progressive bone-conducted hearing loss within a short period of time; ③facial palsy in two patients; ④the laboratory test of ANCA is positive; ⑤conventional treatment of otitis media is ineffective, while glucocorticoid combined with immunosuppressive therapy is effective. Conclusion:OMAAV is a rare disease and prone to misdiagnosis. Early diagnosis and treatment with corticosteroids and immunosuppressants are critical. Invasive tests and surgery during the active phase of OMAAV may aggravate symptoms and should be avoided.
