Embolization of pseudoaneurysm of the internal maxillary artery after orthognathic surgery.
In orthognathic surgery, Le Fort I osteotomy is one of the most often used methods for the correction of dental-facial deformities and is considered technically safe. However, this procedure may lead to diverse complications, including uncommon vascular complications. A clinical case is described of late development of pseudoaneurysm in one of the branches of the maxillary artery in a 20-year-old patient who had undergone Le Fort I osteotomy, bilateral sagittal osteotomy of mandibular branch, and mentoplasty and subsequently treated with embolization. The main forms of treating vascular injuries are reviewed, and embolization is demonstrated to be a technically safe procedure with few complications.
