Jaw Surgery for Gummy Smile, Receding Profile, and Lip Incompetence? (photo)

Possible surgical procedures for the following?

  • Bad lip incompetence at rest, closing lips causes visible chin strain
  • Receding side profile
  • Gummy smile.
  • Lower third of face is 1.5 cms longer
  • Jawline asymmetry. Not easy to see in photo because skin is soft but orthodontist pointed this out. My right jaw is longer than left & pushes chin off center. I get painful TMJ mostly on shorter left side. I did have braces for crossbite as teenager. Jaw issues weren't discussed at that time.

Orthognathic surgery is required

Seeking advice from your orthodontist is the correct first step. Now you need to seek consultation with a board certified oral maxillofacial surgeon who performs corrective jaw surgery. In general you would require a lefort 1 osteotomy of the maxilla that will reposition the upper jaw in a more superior position. This will decrease the gummy smile. Then you will possible need a bilateral sagittal split osteotomy (if your treatment plan calls for this). From your photos your chin is really small and this can definitely be corrected by advancing the chin with a genioplasty.  This will also significantly improve the lip incompetence, the asymmetry, and the muscle strain of the chin muscle.  Best of luck.
