title: Radial forearm and forehead flap reconstruction following resection of a nasal arteriovenous malformation: A case report.
abstract: Arteriovenous malformation (AVM) is a structural vascular abnormality in which the arterial vasculature connects with the venous vasculature without capillary connections. AVM confined to the nasal cavity is considerably rare. Blurred vision can be one of the associated symptoms. A combined approach of complete surgical resection with prior superselective embolization is the treatment of choice. Following resection, the reconstruction of facial defects, particularly in the nasal area, is challenging. The present study reports the rare case of a patient with an AVM in the nasal cavity, in which embolization, resection and flap reconstruction were performed. Embolization and complete surgical resection were used to avoid recurrence. Subsequently, a combination of free radial forearm and forehead flaps was used for the reconstruction of the nasal defect, without prosthesis. To the best of our knowledge, this is the first report of AVM confined to the nasal cavity, managed by a combination of free radial forearm and forehead flap reconstruction following complete resection. The cosmetic results of the procedure were acceptable.
