动静脉畸形(arteriovenous malformation,AVM)最常见于头颈部,其次为四肢,还可发生于身体任何部位的软组织、骨内、器官内,以及中枢神经系统如脑、脊髓、硬脑膜中[1]。口腔颌面部AVM既可单独发生于软组织或颌骨内,亦可二者同时累及,但以发生于成年人颞浅动脉所在的颞部或头皮下软组织中的病变最为多见。其中颌骨由于存在骨内穿越骨髓腔的动静脉血管束而成为全身惟一可发生骨内高流速血管畸形的骨骼[2]。AVM主要是由血管壁显著扩张的动脉与静脉未通 Arteriovenous malformation (AVM) is most commonly seen in the head and neck, followed by limbs, and can occur in soft tissue, in bone, in organs, and in the central nervous system such as the brain, spinal cord, and dura in any part of the body [1 ]. Oral and maxillofacial AVM can occur either in the soft tissue or in the jaw alone or both, but lesions most frequently occur in the temporal or scalp soft tissue where the superficial temporal artery is located. Due to the existence of bone in the bone through the medullary cavity of the arteriovenous vascular bundle and become the only body that can occur high-velocity intraosseous vascular malformations of the skeleton [2]. AVM is mainly failed by the significant expansion of the vessel wall arteries and veins
