초록
Vascular tinnitus, a sort of pulsatile tinnitus, should be differentiated with other sensorineural tinnitus because it is possible to be cured by correction of underlying systemic disease or surgery. The dehiscent high jugular bulb, a common cause of venous pulsatile tinnitus, can be cured by reconstruction of hypotympanum. We present a case of pulsatile tinnitus with dehiscent high jugular bulb which has been treated by surgery. Preoperative microscopic finding showed dark bluish pulsating mass in posteroinferior portion of tympanic membrane. Temporal bone CT showed high jugular bulb with bone defect of hypotympanum. The hypotympanum was reconstructed and high jugular bulb lowered using the harvested bony fragment from mastoid cortical bone. The pulsatile tinnitus disappeared immediately after surgery.
