Submentoplasty For Witch’s Chin Deformity in Denture Patients

Wednesday, July 13th, 2011

The chin is a portion of the jaw bone that not only juts outward but is also enveloped by soft tissue attachments. The mentalis muscle is one of the dominant muscles of the chin. It is a paired central muscle which has a significant effect on the lower lip. It has fibers which attach below the mandibular vestibule, known as the incisive fossa of the mandible, and then descends vertically downward to insert into the skin of the skin. It is a muscle of facial expression as it raises and pushes up the lower lip and causes wrinkling of the chin, making a pout.

While this facial expression function seems rather trivial, if the mentalis muscle loses it bony attachments one will have something to pout about. This is an unfortunate occurrence that occur from intraoral chin procedures and, most commonly, after a chin implant has been removed or from multiple chin surgeries. When the mentalis muscle loses its superior bony anchoring point, the entire chin soft tissue pad can droop. This has a classic name which well defines its appearance, known as a ‘witch’s chin’, with the chin pad falling off of the end of the bone.

The correction of the witch’s chin deformity has been well described with the mainstay treatment approach of mentalis muscle resuspension. Multiple methods of how to fix the muscle to the chin bone have been described. While it is a relatively straightforward procedure from a technical standpoint, getting a stable result with tight tissue adaptation across the convex chin is not always easy or successful.

While the common origin of a witch’s chin is chin implant surgery, many older patients who have never had chin surgery have it. It is actually exceedingly common and everyone has seen someone with it. It is the result of a natural process that largely affects older individuals….tooth loss.

.

With loss of the teeth of the lower jaw and the wearing of dentures, the top portion of the jaw bone known as the alveolus resorbs away. This is the result of no teeth as well as the pressure of wearing dentures on top of this bone. In the front part of the mandible, when the alveolar loss becomes severe, the bone resorbs down to the attachments of the mentalis muscle. If severe enough the bone loss resorbs down to the level of the mentalis muscle’s upper attachments…and the chin pad falls downward.

This is a well recognized facial look in many older individuals. This edentulous witch’s chin is not correctable by mentalis muscle reattachment since there is no bone on which to anchor it. Rather it has to be treated from underneath through a submentoplasty approach. The excessive hanging tissues have to be excised, tightened, and secured to the bottom edge of the chin bone. This will get rid of the inverted v-deformity seen in profile under the chin.

The edentulous witch’s chin deformity is the result of a natural aging process rather than one caused by surgery and cosmetic manipulation. It can be successfully treated by removing the loose hanging tissues rather than muscle resuspension.
