Definition

Mentoplasty is a term that refers to plastic surgery procedures for the chin. It comes from the Latin word mentum, which means chin, and the Greek verb plassein, which means "to form" or "to shape." Mentoplasty is also known as genioplasty or chinplasty.

Purpose

Mentoplasty may be done for several reasons:

• To correct malformations of the chin resulting from developmental abnormalities of the bones in the jaw. Sometimes the jawbones continue to grow on one side of the face but not the other, leading to facial asymmetry. In other instances a part of the jawbone is missing; this condition is known as congenital agenesis of the jaw.
• To reshape a chin that is out of proportion to other facial features.
• As part of gender reassignment...
