Hemangioma is a vascular malformation, there are few congenital benign tumor in infants at birth or shortly after birth, it originated from the remnants of the embryo into vascular cells, hemangioma in oral and maxillofacial region for systemic hemangioma in 60%, most of which occurs in the facial skin, subcutaneous tissue and oral mucosa, such as the tongue, lips, mouth and other organizations, a few occurred in the jaw or deep tissue.
Hemangioma can be divided into capillary hemangioma, cavernous hemangioma and racemose hemangioma according to their clinical manifestations and histological features.
Capillary hemangioma: an abnormal expansion of capillaries. More in the face and oral mucosa. Not higher than the skin is red or purple, perimeter, irregular shape, is higher than the skin Wine porphyritic; rough surface, like bayberry like. When the tumor body is pressed out of the blood, the color of the surface of the tumor is released, and the blood is filled immediately after the pressure is relieved. Cavernous hemangioma: composed of numerous sinusoids of developmental malformations. Blue purple, soft bag. Compressible. The position element moving test is positive, that is, when the tumor body is lower than the cardiac plane, the blood flow in the tumor is blocked, the tumor body increases, and the blood flow of the tumor is higher than that of the heart plane. Sometimes in the soft body of the body and vein stone. Blood coagulation. Racemose hemangioma: a vessel that is markedly dilated by the wall of the blood vessel and is anastomosed directly to the vein. The tumor high up beads, higher surface temperature. Palpation. There is a pulsation, blowing murmur auscultation. The pulsatile pressure and the disappearance of murmur. Diagnosis of hemangioma: tumor appearance (Wine porphyritic or Yang Meizhuang). Fade or shrink. Bit test positive, palpation and venous puncture stone, blood coagulation (sponge), a palpable pulsation, auscultation blowingmurmur, pressure closed arteries and murmur disappeared (plexiform). Angiography showed tumor contrast agent concentration or vascular malformation. Pathological diagnosis. Principles of treatment of hemangioma: 1 surgical treatment, the limitations can be removed, a wide range of partial resection. 2 microwave diathermy, mainly used in the cavernous type. 3 radiation therapy for infantile capillary hemangioma and superficial cavernous hemangioma. 4 sclerotherapy for cavernous hemangioma. 5 cryotherapy for Yang Meizhuang and cavernous hemangioma. 6 hormone therapy for infantile hemangiomas. 7 endovascular embolization for giant cavernous hemangioma. Medication principles: general surgical prophylaxis against infection by the use of sulfa drugs (such as compound sulfamethoxazole) or a major role in the gram positive bacteria (such as red, green, etc.). Poor health or concurrent infections often combined with drugs, commonly used for drug effects on Gram positive bacteria (such as green enzyme) + drug effect on Gram positive bacteria (such as gentamicin) + drug effect on anaerobic bacteria (such as metronidazole). Before and after surgery, patients with severe infection or complications can choose antibiotics according to clinical and drug sensitivity test.
