Hello, Thank you for your question regarding a groin incision thigh lift. I call this a crescent thigh lift. During a crescent medial thigh lift, an incision is placed high in the upper thigh, where the upper thigh meets the groin . The incision is placed in this position so the scar is hidden by most reasonable clothing. During the crescent medial thigh lift, upper thigh skin and fat are removed in a crescent shaped, therefore a crescent thigh lift. The amount of skin and fat that is removed from the upper inner thigh measures approximately the width of your hand. This completely removes the skin and fat in the upper inner thigh. The crescent medial thigh lift does pull some of the skin from the middle thigh. It does not significantly affect the skin and fat around the knee. Often, thigh and leg liposuction is combined with the crescent medial thigh lift. If you have any questions regarding a crescent medial thigh lift, please contact my office at 310-859-7770. Sincerely, Dr. Katzen.
