may leave some scars, but they are usually minimal and well-hidden. The exact location and size of the scars depend on the type of jaw surgery performed and the surgical approach used.    For example, if the surgery is performed through incisions inside the mouth, there will be no visible external scarring. However, if an external incision is required, such as in cases of corrective jaw surgery, a small scar may be visible on the skin.    In general, the scars from jaw surgery tend to be small and well-concealed, and they usually fade over time. Your surgeon will provide you with specific aftercare instructions to help minimize scarring and promote healing.
