Hemangiomas (including maxillofacial hemangiomas) can be biologically divided into three phases, namely the proliferative phase, the stable phase and the regressive phase. Hemangiomas generally continue to grow for 6 to 8 months, and after a resting period of 1 to 2 months, they mostly enter the regressive phase at 8 to 12 months. It is generally believed that the natural regression rate is 50-60% within 5 years of age, 75% within 7 years of age, and 90% within 9 years of age. In clinical treatment, the principles and methods of treatment vary according to the characteristics of each stage of hemangioma. Hemangiomas in the proliferative phase require active treatment, with the aim of removing the lesion or at least delaying its development to create favorable conditions for later treatment. In the receding phase, the aim of treatment is to improve the appearance and function.
