American cubic plastic surgery experts said that with the gradual development of maxillofacial plastic surgery technology, people began to think about this problem. Maybe chin plastic's surgery will make the chin and even the whole face more beautiful and charming. If the mandible is too prominent and the chin is too long, it is necessary to judge whether the whole mandible needs to be corrected or only the chin front surgery according to the combined state of the patient's teeth. If mandibular correction is needed, correct the teeth before the operation. For this kind of plastic surgery, experts suggest that it can be improved by shortening the chin. The so-called long chin shortening operation is to make triangular flaps on both sides of the subcutaneous midline, and its size depends on the degree of submandibular fat accumulation. Then free the flap and remove the excess adipose tissue and fibrous tissue band together. If the skin sags, you should remove the excess skin. Finally, the triangular flap was shifted and sutured, and the suture incision was made into a "Z" shape, hence the name "Z" plasty. This chin plastic operation is performed under local anesthesia, so there will be no pain. Solving the problem of how to shorten the chin is your safest way.
