Abstract

Aberrant internal carotid artery in the middle ear is rarely seen and is usually of little clinical significance if diagnosed correctly. Misdiagnosis and malmanagement, however, can lead to serious complications such as massive bleeding and neurologic sequelae. Authors experienced two cases of aberrant internal carotid artery in the middle ear, which were diagnosed by carotid angiography and temporal bone spiral CT. Here we are reporting these cases with a discussion on efficacy of spiral CT in diagnosing this anomaly.
