Pseudoaneurysm of the facial artery following mandibular bilateral sagittal split osteotomy: A case report.

This article presents a case involving a 16-year-old female patient in whom a pseudoaneurysm of a facial artery branch was diagnosed two weeks after initial orthognathic surgery. The patient presented with a sensation of pressure, accompanied by pulsations synchronised with her heartbeat, located on the right side of the mandible. Ultrasound imaging, followed by CT angiography, confirmed the diagnosis of a pseudoaneurysm within the parotid region. Endovascular embolization effectively stopped blood flow to the pseudoaneurysm, leading to rapid recovery without any lasting complications. A pseudoaneurysm is a rare complication following orthognathic surgery. This complication, as a result of anatomical variation, can have serious consequences if not recognised and treated in time.
