Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is characterized by systemic necrotizing vasculitis, and patients fall into 2 groups: those with proteinase 3-ANCA and those with myeloperoxidase-ANCA. As infections are a trigger of ANCA-associated vasculitis, this disease tends to localize in areas around the upper airway. In this study, the authors compared ear and nasal symptoms between patients with proteinase 3-ANCA and those with myeloperoxidase-ANCA. We undertook a retrospective case series study of 34 patients diagnosed with ANCA-associated vasculitis. The otologic symptoms were divided into 3 types: chronic otitis media, secretory otitis media, and sensorineural hearing loss. Chronic otitis media was more common in patients with proteinase 3-ANCA (P = .001), whereas secretory otitis media was more frequently found in patients with myeloperoxidase-ANCA (P = .007). Crust formation (P = .001), saddle nose (P = .024), and sinusitis (P = .001) were more common in patients with proteinase 3-ANCA than in those with myeloperoxidase-ANCA. Marked differences were observed in the disease spectrum between the 2 ANCA groups.
