Genioplasty is a type of surgery done on the chin. Both plastic surgeons and maxillofacial surgeons (surgeons who work on the mouth and jaw) can perform this type of surgery. Genioplasty is most frequently a cosmetic surgery, meaning people choose to have it for looks and not because of a medical problem. For this reason, it’s often not covered by insurance. Chin surgery is a procedure to reshape the chin to either enlarge it with an implant or reduce its profile with reduction surgery on the bone. Depending on the patient’s needs, chin surgery involves either inserting an implant or moving or reshaping bones.
