Mandibular retraction deformity is common in daily life. Just because it is difficult for people to see their profile, it is difficult to realize that mandibular retraction is a major defect in appearance. Mandibular retraction deformity is mostly caused by congenital mandibular dysplasia or related to heredity. There are also acquired trauma, infection and other reasons, which damage the growth and development center of mandibular solid bone, make it close prematurely, and cause mandibular retraction. Modern medical plastic surgery technology can push the retracted mandible forward to a suitable position, making you a beauty from front to side.
