Chin Surgery or Genioplasty refers to cosmetic surgery operations that aim to improve the appearance of a person's chin, such as by chin reduction (if the chin is too large) or repositioning it (to correct a small or deficient chin). Different types of genioplasty include osseous genioplasty or sliding genioplasty, asymmetric chin point and implant genioplasty. It is an invasive procedure, requiring general anaesthetic. Depending on the type of surgery, the exact process will differ, but generally involves the bone within the chin being broken in a controlled way, allowing it to slide forwards or backwards to be moved into its new position, where it is then fixed into place with screws and metal plates. Surgery is permanent, as the bone fuses into its new position. Genioplasty surgery is not as painful as one might expect, but it does cause some discomfort that is usually worse on the second or third day following the surgery. Post surgery swelling can last for up to two weeks or longer. Genioplasty procedures cost between £3,800 and £6,500, depending on the type of operation and the surgeon.
