内頸動脈鼓室内異常走行例

抄録

We report a rare case of an aberrant internal carotid artery running in the tympanic cavity. The patient was a 5-year-old girl with otitis media exudativa. During a myringotomy of the left ear, a profuse aural hemorrhage occurred. The bleeding was stopped by packing tightly with tampons. A CTscan revealed an aberrant internal carotid artery in the tympanic cavity. To avoid a faulty myringotomy, recognition of this entity is essential, and careful observation preoperatively under a microscope is required.
