Comprehensive Treatment of Upper Lip Arteriovenous Malformation

Mohammad Jafarian et al. J Maxillofac Oral Surg. 2016 Sep.

Abstract

Arteriovenous malformations are uncommon congenital disorders in vascular development. They frequently involve craniofacial structures and result in a morphogenic abnormality with ominous arteriovenous shunting. We present a huge AVM of the upper lip in an 18-year-old patient who was successfully treated by the combination method of presurgical endovascular embolization and complete resection of the lesion. Subsequent surgical defect in upper lip, which involved more than two-third of the lip length, was reconstructed via Webster's modification of cheek advancement flap.

Keywords: Arteriovenous malformations; Embolization; Reconstruction; Resection; Upper lip.
