Pseudoaneurysm of the internal maxillary artery secondary to subcondylar fracture: case report and literature review

Abstract

Pseudoaneurysms are an uncommon complication of mandibular condylar-subcondylar fractures; however, if present, their recognition and management is mandatory to avoid life-threatening situations. The authors report a case of internal maxillary artery pseudoaneurysm rupture that occurred after an open reduction and internal fixation of a mandibular subcondylar fracture, along with a review of the literature.

Radiological investigation of acute mandibular injury

“…[ 78 79 ] Pseudoaneurysms and dissections, particularly those involving major vessels, represent fairly uncommon but potential serious complications, however an increasing number of cases are being reported in literature. [ 79 80 81 82 83 84 85 ] This may be reflective of the increased access to imaging modalities and technological advancements. [ 79 80 ] Other important nonvascular complications associated with condylar fracture dislocations include fractures of the tympanic plate and mandibular fossa, associated dislocation into the external auditory canal and middle cranial fossa, abnormal bony development, and cranial nerve injury.…”
