he patient was a 32-year-old woman, who complained the facial weakness and the tinnitus on the right side, and occasionally the headaches, of two yearsduration.The right external auditory canal was filled with the grayish-pink tumor that had cartilage-like consistency and smooth surface. Another local findings were almost normal without the palsy of the right-sided 7th nerve. The hearing tests revealed the pure conductive deafness on the right ear. The vestibular function was normal. X-ray findings showed a small destructive process on the right petrous bone. Pre- operatively, a biopsy of the graunlar mass in the right external auditory meatus confirmed the original diagnosis of the glomus jugular tumor.The postaural radical mastoidectomy was performed without excessive bleeding under local anesthesia. The main tumor filled the entire external auditory canal, and invaded the lower part of the petrous bone and the base of the external in size of the little finger.After operation, deep X-ray therapy (2400r.) and implanatation of radon seeds (5mc) were applied. There has been no recurrence observed for two years. This case is apparently the third report of the glomus jugulare tumor from Japan.
