Clinicoradiographic aspects of arteriovenous malformations involving the orofacial region: A case series

Vascular malformation consists of a group of tumors that emerge from the vascular origin caused by vascular or lymphoproliferation. Arteriovenous malformations (AVMs) contribute high-flow, creating direct vein artery contact without regular capillary network. AVMs are present at birth or in congenital. Acquired AVMs occur later in life due to hormonal changes or trauma. AVM of the head and neck is a rare vascular anomaly but when present is persistent and progressive in nature and can represent a lethal benign disease and an incomplete resection frequently leads to recurrence of the lesion. Here, we present a series of three cases of AVM reported during 2019-2022 involving the orofacial region.
