Those who feel their face lacks a certain amount of proportion often have their chin altered to enhance their profile. Chin augmentation, or mentoplasty, usually involves either inserting an implant into the chin or changing the shape of the bone. This is often done to improve facial symmetry after another cosmetic procedure. Most patients can return to normal living a week after surgery, but numbness or discomfort may continue for three months. Men received 58 percent of the 15,161 chin augmentation surgeries in 2005. You won't take it on the chin when paying for this operation because physician's fees average $1,600.
