FACE - Chin Mentoplasty   The chin constitutes one of the main references in an aesthetic study of the face. The ideal chin should be located within certain aesthetic limits, working in harmony with the nose, the eyes, the mouth, etc. It can be located in a more advanced or in a more drawn back position. Both cases can be surgically corrected. The most common mentoplasty aims at correcting the retro-position (retracted chin) by introducing a silicon prosthesis.
