Fell on Chin in 5th Grade, and Has Been Uneven Since. What Can I Do to Fix It? How Much Will It Cost? (photo)

Cost factors vary significantly for a number of good reasons: Prices vary greatly because the surgery itself encompasses a wide range of techniques that can be performed to different extents. My recommendation is to first find the most qualified surgeons where you want the surgery performed that are board certified by the American Board of Plastic Surgery you trust, then compare prices between them. See the below link on suggestions on how to find the most qualified plastic surgeon for your procedure. General Factors that influence the price of plastic surgery include:


1. Location - Will it be performed in a hospital with an overnight stay, an independent out- patient facility or a doctor’s office? Geographical location also has a significant influence. RealSelf has average charges for most areas of the USA.


2. Type of Anesthesia - local, IV sedation or General Anesthesia? Will a board certified anesthesiologist, nurse anesthetist, or an RN be used?
    
      3. Experience and training of your surgeon. The best and longest trained is most often a plastic surgeon board certified by the American Board of Plastic Surgery
   
      4. Length and Complexity of Surgery - how difficult will your surgery be and how long it will take, etc. Will other complementary procedures also be also performed during the same surgery?

Was there any injury to your jaw bone at the time of your injury?  If not, the unevenness most likely is due to some scar tissue around the area.  If it is just scar tissue, you could have surgery to remove some of the excess tissue which would help to even out your appearance.  This would be a fairly simple procedure and could be done in the office with just local anesthesia.  The cost will vary by surgeon but should be relatively inexpensive.  

Most likely that represents an area of bone that was deposited due to the bleeding that took place under the periosteum from the fall which can happen at a younger age due to ongoing overall growth. That could be burred down/smoothed out from a small incision under the chin or could even be done from inside the mouth. (although it is a little easier recovery from below)
