Pseudoaneurysms are a known complication following facial trauma and orthognathic surgery. Few reports exist of this clinical entity following traditional open techniques of repair, and none have been associated with endoscopic-assisted open reduction and internal fixation (ORIF) of a subcondylar fracture. We present a case of a 33-year-old man who developed pseudoaneurysm after endoscopic-assisted ORIF as well as a review of the literature on this topic. While uncommon, this is a potential complication that should be recognized with the use of endoscopic-assisted repair of mandibular fractures.
