Introduction: Pseudoaneurysm of the facial artery is a rare event. Rupture of the arterial wall leads to extravasation of blood into the surrounding tissue, followed by tamponade and clot formation. Left untreated this has the potential to cause catastrophic haemorrhage.Case Report: A 59-year-old male presented to our department with bony ankylosis of his temporomandibular joints bilaterally as a result of previous osteomyelitis. He underwent bilateral temperomandibular joint replacements in a two-stage procedure. Following his discharge he presented to the emergency department six weeks later in haemorrhagic shock, having lost significant blood volume from a pulsatile lesion over his right mandible. Computed tomography angiography revealed a pseudoaneurysm of the right facial artery. He proceeded to emergent embolisation with resolution of the pseudoaneurysm.
