Chin plastic surgery focuses on addressing disproportions, asymmetry, and imbalances in this area. These are deviations that appear inappropriate and disproportionate when looking at the face, and this modification can achieve a harmonious shape. It is considered normal when the root of the nose, upper lip, and chin projection form an imaginary common line. However, the shape and size of the chin are formed not only by the lower projection with the jawbone but also by soft tissues, which need to be assessed for quality as they may lose elasticity over time.

Chin plastic surgery allows for effective reduction, augmentation, and repositioning of the jaw with or without an implant, always ensuring that the proportions relative to other facial features are preserved as optimally as possible.
