Facial asymmetry refers to a twisted balance of the left and right sides at the centerline of the face. If you have facial asymmetry, you should improve them because they often involve discomfort with food intake, problems with pronunciation, and pain in the jaw joint. Double-jaw surgery is required if malocclusion, protruded lips, and lantern jaws. Needs a fine surgical plan that straightens the centerline of the face, followed by bone resection to correct the incision and asymmetry of the upper and lower jaw bones. If the entire centerline of the face is asymmetrical in the lower jawbone, the genioplasty surgery that moves the tip of the chin can be done.
