Mentoplasty is the surgical procedure focused on modifying the size or position of the chin and improving its proportion to the face. It is a highly demanded technique, since together with the nose it defines the facial profile of a person, greatly affecting the aesthetic image.

It is performed when the patient has a very small chin, when the chin is too prominent or to correct abnormalities in the development of the jaw bones such as facial asymmetry. In any case, a harmonization of the facial features is sought.
