Suggestion: hello, generally speaking, improper chin augmentation surgery may have two sequelae: the first is micrognathia, which is a serious deformity. This kind of people have mandibular hypoplasia, complicated with dentition recession, often accompanied by other congenital defects, which require the cooperation of plastic surgery, oral surgery and orthodontics. This kind of patient is quite rare. The second sequela of chin augmentation is the common chin deformity, which means that the position of chin is behind the second vertical line, but the occlusion of teeth is normal, so as long as the face is matched, chin padding can be used to correct this defect. You don't need to worry about the sequelae of chin augmentation. If you want to create a better chin image, you can use chin augmentation surgery. Generally speaking, the sequela of chin augmentation is not as serious as expected. As long as you choose a regular medical beauty institution, do detailed consultation before operation and do good nursing after operation, the sequelae of chin augmentation can basically be avoided. Chin augmentation surgery can bring significant changes to the chin with few complications. After the operation, the position of the chin prosthesis may be displaced due to careless collision or premature removal of the fixing belt, and it is necessary to restore the normal position through chin augmentation surgery again.
