Abstract
Carotid-cavernous sinus fistulas (CCFs) are abnormal connections between the cavernous sinus and the carotid arterial system (the internal carotid artery, external carotid artery, or both). CCFs may be classified as spontaneous or acquired and as direct (high blood flow) or dural (low blood flow) [[1]]. Direct CCFs represent 70% to 90% of all CCFs, and mostly result from head trauma, especially basal skull fractures [[2]]. Patients with CCFs may present with signs and symptoms such as conjunctival chemosis, decreased vision, proptosis, diplopia, orbital pain, audible bruits, headache, and blindness [[2] [3]]. In this report, we present the case of a 49-year-old man with a CCF and ophthalmic symptoms, resulting from a left zygomaticomaxillary complex fracture.
