title: Supraclavicular flap: reconstructive strategy for massive facial arteriovenous malformations.
abstract: Arteriovenous malformations (AVMs) are uncommon errors of vascular morphogenesis. Hemodynamically, they are high-flow lesions. Approximately 50% of AVMs are located in the craniofacial region. The successful treatment of vascular anomalies depends on the profound knowledge of the biologic behavior of vascular lesions and their correct classification. Vascular malformations that persist lifelong require treatment in most cases, especially when clinical symptoms occur. On the basis of individual parameters such as the diameter, location, or growth behavior, different therapeutic options such as cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgical intervention, and/or embolization can be performed successfully. Subtotal excision or proximal ligation of the feeding vessel frequently results in rapid progression of the AVMs. Hence, the correct treatment consists of highly selective embolization (superselective) followed by complete resection 24 to 48 hours later. Reconstructive procedures in the head and neck region use a wide range of flaps for defect closure. The methods range from local, mostly fasciocutaneous flaps and skin grafts, to free microsurgical flaps. To ensure a satisfactory functional and aesthetic result, good texture and color of the flap are always essential. Moreover, the donor-site defect needs to be reduced, with no resulting functional or aesthetic impairment. The supraclavicular flap has been used successfully for difficult facial reconstruction cases, providing acceptable results without using microsurgical techniques. We treated 2 patients with facial AVM by this method. Both of the lesions were located within the cheek and lip. There were no procedure-related complications, and the cosmetic results were excellent.
