I'm a 19 year old woman, and I've been very uncomfortable with the length of my face for many years. I've given it a lot of thought, and decided that I want this fixed. My problem is excessive maxilla length. Due to this, my face is unbalanced, and I'd like to shorten my mid-face/maxilla by at least 2 cm. I do not have a gummy smile or overbite, I just want to shorten my maxilla. Is this unrealistic? How much would it cost? I can not find very much information on this.
