To augment the chin, the surgeon begins by making an incision either in the natural crease line just under the chin or inside the mouth, where gum and lower lip meet. By gently stretching this tissue, the surgeon creates a space where an implant can be inserted. This implant, made of synthetic material that feels much like natural tissue normally found in the chin, is available in a wide variety of sizes and shapes. This allows custom fitting of the implant to the configurations of the patient’s face. After implantation, the surgeon uses fine sutures to close the incision. When the incision is inside the mouth, no scarring is visible. If the incision is under the chin, the scar is usually imperceptible.

In chin reduction surgery, incisions are made either in the mouth or under the chin. The surgeon sculpts the bone to a more pleasing size. For orthognathic surgery, the surgeon will make an incision inside the mouth and reposition the facial bones. The procedure, depending on the extent of the work, takes from less than an hour to approximately three hours.
