[Capillary-venous angioma of the temporo-masseteric region]

Angioma of temporomasseteric region is a capillariovenous malformation in the temporomasseteric groove which can extend into adjacent facial zones. It forms a well defined clinicopathological entity. Clinically these angiomas present typical signs of a slow output capillariovenous angioma. Several patients were investigated by standard radiology, tomography and scan imaging, allowing detection of bony, particularly maxillary deformities, and by preoperative laboratory examinations. Treatment is by first stage embolization in situ of the angioma using sclerosing agents to reduce risk of perioperative bleeding and disseminated intravascular coagulation. The second surgical stage varies with the size and site of the lesion. Treatment should be carried out fairly early in childhood to avoid facial skeletal and muscular deformities. This hopefully allows harmonious growth of face with preservation of functions that risk alteration by the temporomasseteric angioma.
