Abstract
An arteriovenous malformation (AVM) is an infrequent congenital vascular anomaly that can affect the vasculature and involve the endothelium and neighboring cells of any anatomical structure. AVMs are characterized histologically by abnormal AV shunts with atypical interconnecting capillary beds. AVM can cause functional and esthetic issues like face asymmetry, pain, osteolytic changes, and unanticipated hemorrhage or squeeze and tear of the surrounding tissue without causing any symptoms. The literature search yielded limited case reports on AVMs in the facial region. Insufficient diagnosis, limited knowledge, and a lack of literature can lead to severe bleeding and potentially fatal hemorrhagic incidents following dental procedures like tooth extraction, surgery, puncture wounds, or blunt injuries in the affected area. In this manuscript, we report a case of AV malformation involving the left cheek and buccal mucosa region in a 37-year-old male patient who reported uncontrolled bleeding after trauma. This report highlights the management of AV malformation in an emergency by facial artery ligation and surgical excision.
