Hello, the bone removed in the operation can't be repaired, and the bone will not develop again in adulthood. Therefore, bones that have been excessively excised cannot grow back on their own.

For example, if maxillofacial surgery fails, contour repair surgery is necessary. Although there are many hospitals that can do contour plastic surgery, the same surgery is rarely done for repair surgery.

Moreover, repair surgery is much more troublesome than simple contour plastic surgery, and it also has great restrictions on the choice of materials, and sometimes it can't be repaired because of too much resection.

Therefore, if contour plastic surgery fails and you want to repair it, you must go to a regular hospital, and the professional dean will give you a more suitable surgical plan according to your own situation.

I hope my suggestion is helpful to you and everything goes well ~
