If your face is long due to your nose, that is literally it. There is no surgery that can completely shorten the face to a desired length. A lot of people will tell you a bimax + CCW rotation but that will merely shorten the philtrum and create the illusion of a shorter midface. A lip lift would make your philtrum shorter, if the philtrum is the reason your midface looks long
