The majority of carotid aneurysms are endocranial, and aneurysms of the extracranial carotid arteries are extremely rare. Traumatic aneurysms that are located in the head and neck are usually confined to the great vessels of the neck. The branches of the extracranial carotid arteries in the head and face are small and deeply located, and so partial transection resulting in pseudoaneurysm is uncommon. Authors have experienced a case of sphenopalatine artery aneurysm associated with recurrent and massive epistaxis following panfacial bone fracture. So we report this case with review of the literature.
