 BACKGROUND:Le FortⅠ osteotomy, one of the most common techniques applied to correct jaw deformities, is generally considered operatively safe. However, a few articles reported that this procedure can lead to formation of arteriovenous fistulae(AVF)involving the maxillary artery infrequently.

 CASE REPORT:A man in his 40s with a jaw deformity underwent Le FortⅠ osteotomy. Two days later, he noticed pulsating tinnitus in his right ear. Angiography revealed AVF between the proximal part of the maxillary artery(first segment)and the pterygoid plexus. On further evaluation, AVF were embolized with n-butyl-2-cyanoacrylate(NBCA). Obliteration of AVF was confirmed on the final angiography. The tinnitus resolved shortly after the embolization.

 CONCLUSION:Embolization with NBCA is a promising treatment for maxillary AVF after Le FortⅠ osteotomy.
