摘要

中耳之異位性內頸動脈是一種很稀有的病症，容易造成誤診，甚至引發嚴重的併發症。事實上，大約有百分之一的新病例是被誤診的。我們在此報告一個中耳之異位性內頸動脈的病例，其臨床上的表現為耳悶，聽力減退及頭暈。將探討病因，臨床上的特徵以及處理方法。我們的經驗顯示，當一個中耳的異位性內頸動脈確定診斷時，局部治療及耳朵的手術都是必須避免的。

Aberrant internal carotid artery in the middle ear is rare and may be misdiagnosed, leading to severe complications. Indeed, approximately 1% of new cases are misdiagnosed. We present here a case of aberrant internal carotid artery with the symptoms of aural fullness, hearing impairment, and vertigo. The aetiology, clinical characteristics, and management of this case are discussed. Our experience illustrates that after confirmation of the diagnosis of aberrant internal carotid artery, localized treatment and/or surgical procedures should be avoided.
