The diagnosis of “cavernous hemangioma” has been modified to “venous malformation” because the essence of cavernous hemangioma is the abnormal expansion of veins. The cause of the disease is still unclear and has little to do with heredity. It will not affect your future fertility, but the lesion will gradually increase in size. Smaller venous malformations can be treated without any treatment. If it is clear that the lesions can be drawn back from the veins, you can choose to treat them with a combination of anhydrous alcohol and pinyamycin injections, which can harden the tumor, and most of the venous malformations can be treated better with several injections. Most of the venous malformations can be treated well by several injections. For some lesions that are clear in scope and located outside the head and face, surgical excision can also be performed. The YAG laser coagulation of the surface of the lesion or insertional laser irradiation of the tumor is a good option for the more difficult treatment of venous malformations in the head, face, and mouth. It has also been reported that the use of copper needles inserted and left in the tumor can cause gradual atrophy of the tumor through positive and negative charge effects.
