Protruding jaw bone, perhaps?

Consultation. You should have a detailed clinical examination with the appropriate studies to determine if your protruding jaw is strictly a cosmetic problem and/or a functional problem. Many patients with a protruding jaw also have a malocclusion (bite) problem and cannot chew correctly. If a malocclusion is present, a combination of orthodontics and orthognathic (jaw) surgery may be indicated for correction.
See an orthodontist. for examination and records to determine if is skeletal or the lower teeth being positioned further forward. If the patient is an adult, and the underbite is skeletal, surgery is usually required. See your orthodontist.

Yes. Depending on the degree of protrusion, a recession genioplasty can be done. In this operation, the chin bone is cut off the rest of the mandible, slid backwards and fixed into place with screws/plates so it does not protrude as much. This is done by some plastic surgeons or by maxillofacial surgeons.
Perhaps. If your jaw bone is protruding cosmetically due to a developmental problem, it can be reduced. If the jaw bone is protruding due to a pathological process, it should be removed and biopsied.
