Genioplasty, also known as chin surgery or chin reconstruction, is a cosmetic or reconstructive surgical procedure aimed at enhancing the appearance or function of the chin. This procedure is commonly performed to correct a recessed (weak or small) chin, a protruding chin, or to address issues related to facial balance, symmetry, or congenital deformities. Genioplasty can be either cosmetic (aesthetic improvement) or functional (addressing underlying medical conditions).
