Abstract
In 16 of 19 patients with biopsy-proved Wegener''s granulomatosis the early manifestations were limited to the ear and nose. The audiological data of 13 patients revealed middle ear involvement in 16 of 26 ears. Twenty-one of 26 ears presented with a low to moderate sensorineural hearing loss. One ear remained deaf after a sudden hearing loss in the early stage of the disease. Serologically, 4 of 6 tested patients with sensorineural hearing loss demonstrated antibodies against sarcolemma. One patient showed antinuclear antibodies. It is remarkable that these antibodies can often be detected in classic inner ear disorders. The course of inner ear function, serum findings and the success of immunosuppressive therapy in Wegener''s granulomatosis are comparable with immunologically mediated vasculitis in the inner ear.
