[Traumatic false aneurysm associated with closed fractures of the mandible. Apropos of 3 cases].

The authors report 3 cases of trauma induced false aneurysm (internal maxillary, external carotid and internal subpetrous carotid arteries) associated to closed mandibular fractures. These rare vascular complications of ill-defined pathogeny are often due to high speed facial impact. Clinical presentation is polymorphous (pseudo-parotidis, neurological deficit) and arteriography is the main step of the paraclinic investigation. The treatment essentially depend upon both the location and the evolutivity of the false aneurysm.
