title: Novel endovascular treatment of enlarging facial artery pseudoaneurysm resulting from molar extraction: a case report.
abstract: OBJECTIVE
  A novel endovascular therapy to treat a pseudoaneurysm as a complication of molar tooth extraction is described.
  
  
  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.
