Arteriovenous Fistula of the Middle Meningeal Artery—A Rare Complication After Arthroscopic Temporomandibular Joint Surgery Readily Amenable to Endovascular Treatment

The development of a traumatic arteriovenous fistula after arthroscopic surgery of the temporomandibular joint (TMJ) is an unusual event that has been limited to a few case reports. These have generally involved the superficial temporal artery and surrounding venous outlets. No cases of either postoperative or post-traumatic arteriovenous fistulas involving the extracranial middle meningeal artery (MMA), which is located on the medial surface of the TMJ, have been previously reported. We report, to our knowledge, the first case of this unusual complication and describe its successful endovascular management.
