For a long face with a medium-long face or a well-developed chin, if you want to shorten the length of the ideal medium-long face ratio, you can achieve a three-dimensional image through surgery. There are many reasons for the long face, such as too developed chin, developed upper and lower jaws and protruding after operation. According to the patient's bone condition and symptoms of long face, different types of surgery were used to shorten the long face after diagnosis.

1, long face caused by overdevelopment of chin bone.

Because the maxilla is too thick and too many gums are exposed when laughing, it is necessary to correct the maxilla and mandible at the same time. "If the maxilla is too long, mainly do bimaxillary surgery?" Because the length of the maxilla only shortens the maxilla, which will lead to malocclusion of teeth, it is necessary to raise the maxilla and perform bimaxillary surgery for the normal occlusion of teeth.

2, the long face caused by the sky.

Because the mandible is too developed, the lower part becomes longer and protrudes forward. Combined with facial bone structure and other parts, only mandibular surgery or maxillary surgery can be done, and bimaxillary surgery can be done.

Mandibular osteotomy can only be done if the mandible is long (covering the sky), and bimaxillary surgery can be done at the same time according to different situations! "Jaw osteotomy refers to the method of extending the osteotomy line downward to get the desired line in order to prevent nerve injury, but also to consider the functional part (nerve injury) to shorten the length of the chin through surgery, which requires professional doctors to have rich medical experience.
