Management of pseudoaneurysm of internal maxillary artery resulting from trauma

Sekhar Chakrabarty et al. J Maxillofac Oral Surg. 2015 Mar.

Abstract

Pseudoaneurysm of internal maxillary artery following trauma is a rare clinical entity. A rapidly growing swelling in the facial region following fracture of the mandibular subcondylar region is an indication of a developing aneurysm. A case of pseudoaneurysm of the internal maxillary artery following condylar fracture of mandible is reported. The case was treated successfully by surgery.

Keywords: Internal maxillary artery; Mandibular condylar fracture; Pseudoaneurysm.
