Hemifacial microsomia was introduced by Gorlin and Pindborg in 1964. Clinical manifestations: underdevelopment of the maxilla, mandible, zygomatic arch, ear, parotid gland and V, VII cerebral nerve, often accompanied by a lack of muscle and soft tissue thickness. Commonly used surgical methods include: osteotomy, autologous allograft bone grafting, implantation of tissue substitutes, and bone lengthening. Clinically, we should choose a treatment plan that is problem-specific, based on the patient’s age, the degree of deformity, and the cumulative range. It is recommended that the first visit be around 6 years of age for a thorough evaluation. A comprehensive planning and scheduling of future therapeutic procedures.
