41 year-old before and 3 weeks after neck liposuction Our 41 year-old patient came to us wanting to get rid of stubborn fat underneath her chin that seemed resistant to diet and exercise. She underwent neck liposuction in our clinic under local anesthesia. The procedure took 15 minutes. These are her results 3 weeks after neck liposuction. These results are why Dr. Maia is known as one of the best plastic surgeons in the D.C. area.
