Purpose: A novel endovascular therapy to treat a pseudoaneurysm as a complication of molar tooth extraction is described.
Patients and methods: A 20-year-old man presented 2 weeks after third molar tooth extraction with an enlarging pulsatile jaw mass, identified as a facial artery pseudoaneurysm. Endovascular embolization with microcoils and a liquid embolic agent, Onyx, was performed. The use of Onyx in this manner is an off-label use.
Results: Immediately after treatment, the pulsatile mass resolved and remained obliterated at 2 months of follow-up.
Conclusions: Onyx embolization of facial artery vascular lesions can be safely accomplished while avoiding microvascular complications and provides a satisfactory and durable result.
