1.Characteristics of infantile hemangioma The incidence of infantile hemangioma is very high, with foreign literature reporting up to 2%-10%. About 1/3 of the lesions are present at birth and 2/3 of the lesions appear two weeks after birth, more in females than males. The lesions grow rapidly in stages until the child is one year old, and then stabilize and begin to subside after that age. Most lesions regress spontaneously, but the length of the regression period varies, with the longest lasting until about 12 years of age. Hemangiomas that occur superficially on the skin are red in color and generally protrude from the skin surface. Hemangiomas that occur subcutaneously or under the mucous membranes tend to be cyanotic in color. Deeper hemangiomas tend to have normal skin color, and the lesion appears as a moderately soft mass, usually in the parotid area. There are also cases in which both skin and deeper parts occur at the same time. 2.Treatment methods of infantile hemangioma There are many treatment methods for hemangioma, such as propranolol oral, oral or local injection of hormone, interferon injection, sclerotherapy, herbal dressing, isotope dressing or injection, imiquimod application, laser treatment, surgical excision and so on. The specific choice of treatment plan needs to be determined by an experienced specialist after a comprehensive evaluation of the child’s condition. 3.Beware of over-treatment of infant hemangioma Because many doctors do not know the biological characteristics of hemangioma, and parents are eager to seek treatment, over-treatment often occurs. Frequent or inappropriate treatment greatly increases the medical burden and medical risk of patients. For example, unnecessary surgery may be performed on the child, and overtreatment may cause scar formation, skin atrophy, abnormal skin color, and inappropriate treatment of the lips, nose, and eyelids may cause facial deformities that are difficult to correct. The basic concept of treatment for infant hemangioma includes long-term observation, moderate control treatment, and later revision treatment. According to the age of the child, the location, size and growth period of the lesion, a scientific and reasonable personalized treatment plan is formulated. For example, for lesions that are hidden, small in size and slow in growth, close observation and long-term follow-up are possible; deep parotid hemangiomas are generally treated with active early control therapy; facial skin lesions are treated with moderate control therapy and treatment methods are flexibly selected according to the response of the lesion to treatment; for areas that have a great impact on facial appearance, such as the lips, nose, ears and eyelids, mild treatment methods are chosen as much as possible to avoid over-treatment, which may cause tissue deformity; for lesions that are large in size, the treatment methods are not suitable for children. For cases with large size and serious functional disorders, early surgical excision combined with other methods are used depending on the situation; patients who have reached the completion stage of remission and have left facial deformities generally choose surgical repair.
