Carotid cavernous fistula after minimal facial trauma. Report of a case

The carotid cavernous fistula has historically been associated with extensive facial trauma as a result of direct or indirect forces. Most fistulas of traumatic origin develop as a result of a fracture through the base of the skull, which produces a force causing laceration of the internal carotid artery in the region where it approximates the cavernous sinus. We report a case in which apparently minimal head trauma resulted in the development of a carotid cavernous fistula. The rather innocuous presentation of this complication requires particular attention by the caregiver in assessing the patient sustaining maxillofacial trauma.
