At the time when this beautiful lady came to see Dr. Fushun Ma she wanted a chin implant to make her small chin bigger. After careful examination Dr. Ma believed her chin receding was moderate degree. In this instance a large implant should be used if a simple chin implant surgery was performed. As this lady is still young the implant will remain in her body form many many years side effect such as local disfigure, capsule contraction and local discomfort could happen over years of localized depression caused surrounding soft tissue atrophy. So Dr. Fushun Ma suggested her doing Advancement Genioplasty.
Like other patients this girl didn't know anything about Advancement Genioplasty. The good thing is that she is well educated and quick understanding. She instantly grabbed the major advantages and disadvantages of chin implant and chin osteotomy surgery. Then she agreed to change the original surgery plan to Advancement Genioplasty.
Her operation and post operation recovery was eventless. Two months after operation she went back to see Dr. Ma happily. She told Dr. Ma that her friends and relatives all agreed she is more beautiful than before. No body found out that she underwent surgery without her disclosing the fact. She asked Dr. Ma if the fixing titanium plate and screw need to remove. Dr. Ma told her that the fixation instruments are very safe and not necessarily to remove. If she doesn't want them to stay in the body she can come one year later and remove it under local anesthesia with a minimal invasive surgery.
Dr. Ma's Comment
This beautiful girl has shining skin, curved eyebrow, big eyes straight nose. The only draw back on her face was that her chin was small and receding. The small chin made her lips protruding giving a unhappy expression and unbalanced profile.
When one's upper and lower lips look reaching out in profile we tend to believe there is a bimaxillary protusion(upper and lower jaw overgrowth) exist and a bimaxillary reduction surgery then would be suggested. However many upper and lower lips protruding patients actually have no protruding maxilla but a small chin only. In this instance a simple surgery of Advancement Genioplasty will perfectly improve the the candidates visage. Just like this beautiful girl at the first glance we may think she had bimaxillary protruding. After careful analyze we could find out that her small chin gave her this unwanted facial outline. An Advancement Genioplasty mended her face in a great deal.
