In the United States plastic surgeons tend to lean more towards recommending chin implants while oral surgeons tend to recommend a sliding genioplasty. Both procedures have advantages and disadvantages. In more severe cases the sliding genioplasty is probably a better procedure. In the end the most important variable is finding the most experienced and talented provider. This could be a plastic surgeon or an oral surgeon since both specialties contribute to this condition. There are certainly oral surgeons who do implants and plastic surgeons who do the sliding genioplasty. I’m only sharing what my experiences have been. This could be different in different parts of the world. Best, Mats Hagstrom MD
