The temporal bone was examined in a 35-year-old female with Wegener's granuromatosis. Her disease localized in the nasal cavities and the orbita, but did not exist in the lung and the kidney. The pure tone audiometry showed the moderate combined deafness of both ears. Right temporal bone findings: The surroundings of the auditory ossicles, epitympanum and eustachian tube were filled with fibrous tissue. The cochlea showed slightly flattend organ of Corti and slightly collapsed Reissner's membrane. The internal auditory canal was infiltrated with leukocytes. The VIIIth nerve was not degenerated. Left temporal bone findings: The hypertrophic submucous tissues and fibrous tissue were seen in the middle ear.
