Mentoplasty is an aesthetic surgery that restructuring of the jaw to make it compatible with the face. This surgery improves the appearance of the chin and the overall proportions of the face. There are common consensus facial features that can make an individual look over or under attractive. All the structures on the face should be harmonious and balanced within themselves. In addition to the fact that the relations, angles and distances of these structures with each other are different in each person, "ideal values" can be calculated for each person. The ideal jaw position should be 2-3 mm behind an imaginary vertical line drawn downward from the base of the nose. A deviation of more than 2-3 mm is considered a weak jaw, and vice versa, a strong jaw. For women, the ideal jaw position may be slightly behind this ideal place, which creates a more desirable aesthetic appearance. For men, a strong jawline that gives a masculine look is preferred.
