Hemangioma can be essentially divided into two types: one is caused by abnormal vascular development during embryonic development, excessive vascular development or abnormal differentiation of blood vessels (hamartoma), and the other is caused by vascular endothelium. A recent article published in the "Chinese Journal of Traditional Chinese and Western Medicine" shows that the incidence of hemangioma in humans is relatively high. Oral and maxillofacial hemangiomas account for 60% of the total body count, among which oral hemangiomas occur. The rate is 23.49%. Since the growth of oral and maxillofacial hemangioma directly affects the appearance and function of the face, treatment methods have become a topic of constant discussion in the medical community. Hemangioma is a common benign tumor in the oral and maxillofacial area. It is caused by the proliferation of vascular endothelium. It can generally be divided into capillary hemangioma, cavernous hemangioma and vine hemangioma. The symptoms of different types of hemangioma are also different. The clinical manifestations of oral hemangioma are capillary hemangioma: the tumor is It is composed of a large number of intertwined and dilated capillaries. It appears as a bright red or purple patch that is flush with the skin surface or slightly raised, with clear borders, irregular shape, and varying sizes. When the tumor is pressed with fingers, the pressure will recede. Afterwards, the color returns. Cavernous hemangioma: The tumor consists of enlarged blood vessel cavities and blood sinusoids lined with endothelial cells. The blood sinusoids are of varying sizes and are filled with venous blood and show no communication with each other. Symptoms are soft and slow-growing. When the head is lowered, the tumor expands due to congestion, and the tumor returns to its original shape after returning to normal position. If the surface of the tumor or the mucous membrane is purple, the skin color will be normal. The mass is soft at diagnosis, with unclear borders and no tenderness. It shrinks when squeezed and returns to its original size after the pressure is relieved. The tumor is mainly formed by the anastomosis of dilated arteries and veins and appears as a bead-shaped or earthworm-shaped tumor. . There is a sense of pulsation and tremor on palpation, and there is a blowing noise on auscultation.

If all the arteries supplying blood are compressed, the above-mentioned pulsations and murmurs will disappear.
