Dr. Kawamoto: The first patient is a 27-year-old woman who complains about an excessively large chin (Figure 1, A and B). She has already undergone fairly extensive orthodontic therapy to convert a class III malocclusion to a class I occlusion (Figure 1, C). If this patient came into your office and said, “I don't really like this chin,” how would you advise her, Dr. Foster?

Dr. Foster: I have found this problem very difficult to treat. The temptation here would be to simply remove some of the bony prominence with a burr via a degloving approach. Although this approach has been used by some plastic surgeons, it can produce unpredictable results. If the soft tissue envelope doesn't contract and adhere properly, chin ptosis and unevenness may result, an outcome even more difficult to correct than the original deformity. A better approach would be to osteotomize the chin and set it back with some bone removal, preserving the attachment of chin pad and musculature to the bone (Figure 1, D).
