Long-term bony and soft tissue stability following advancement genioplasty.

Twenty-three patients who had undergone advancement genioplasty were evaluated an average of over 3 years postsurgically for bone and soft tissue stability. Traced serial cephalometric radiographs revealed no discernible bony remodeling from gnathion to the menton region. Six cases showed minor posterior shifting of the inferior border segment. Although good correlation existed between hard and soft tissue movement, minor soft tissue variation occurred without obvious correlation to bony remodeling.
