Patients of objective tinnitus are relatively rare. Aneurysms of superficial temporal artery are known as one of origin of objective tinnitus. A 51-year-old woman had an incised wound by windowpane in the front of light ear. The wound was closed by sutures. She was aware of tinnitus immediately after suture. The tinnitus was objectively audible with otoscope. Eighteen days later, she noticed the mass in the left preauricular region. An aneurysm of the superficial temporal artery was detected by MR angiography. The aneurysm was removed by surgery, one year after she had injured. The tinnitus disappeared immediately and did not recur following the treatment.
