Abstract

PURPOSE: The mandibular ramus sagittal split osteotomy is a common procedure in cosmetic surgery. A late complication of this procedure, pseudoaneurysm rarely happens. The purpose of this case is to present our experience that is rare late vascular complication after mandibular ramus sagittal split osteotomy.
METHODS
A 21-year-old male was operated by local plastic surgeon for treatment of mandibular prognathism. After 9 days, the man was transferred to our hospital with persistent bleeding and swelling on the mandibular area. We operated the man three times and failed to control hemorrhage. Therefore, we did angiography and found the pseudoaneurysm on the buccal and pterygoid branches of internal maxillary artery. Then we did selective embolization for removal of the pseudoaneurysm.
RESULTS
The man was operated using the therapeutic embolization, and the pseudoaneurysm was removed. The results were successful, and we couldn't find any bleeding and the pseudoaneurysm during the follow-up of 12 months.
CONCLUSION
The selective embolization is the good therapeutic method of late vascular complication after mandibular ramus sagittal split osteotomy.
