Jaw and chin Jaw and chin recontouring Like the forehead, there are specific traits that are generally more common in male chins and jaws. The back corners of male jaws tend to be fuller. The bone tends to have a sharper angle and flares out away from the face. Women's jaws tend to be rounded or straight from ear to chin, and they tend to be less full and square in the back.
Female chins tend to come to one point in the middle.
Men's tend to have two points directly below the canine teeth and a flat part between the points . This adds to men's chins looking fuller and more square, and women's looking more tapered. Male chins also tend to have more vertical height, so their chins then to be longer from the lower lip to the bas of the chin. The surgeon then uses a device to stretch the skin open and expose the jawbone. Ramus reduction , or angle of mandible reduction , involves removing bone from the flared angle back near the ears.
