The previous concept of infantile hemangioma was to wait for observation, but this concept needs to be changed. It should be changed to early active intervention, because it is difficult to determine the time of regression and the degree of regression by waiting for observation, which often brings serious psychological burden to many children and parents. Infantile hemangiomas are clinically divided into 3 phases: rapid growth phase (0-1 year old), regression phase (1-5 years old) and regression completion phase (5-10 years old). According to the clinical manifestations, they are further divided into superficial, deep-lying and mixed types. The treatment of choice for superficial hemangiomas in infants and children is oral propranolol, followed by wet application of timolol solution. For deep hemangiomas, oral propranolol is preferred, and for mixed types, oral propranolol and timolol solution with wet compresses are preferred. Because of the limited penetration depth of laser, laser is suitable for superficial hemangiomas or mixed superficial hemangiomas. Surgical treatment is suitable for residual lesions of regressing hemangiomas.
