Chin augmentation can be done effectively with a sliding genioplasty, using implants, or with the use of fillers. Fillers are temporary, but are very forgiving and easily adjustable, giving them certain advantages and disadvantages. Implants and sliding genioplasty, likewise have certain advantages and disadvantages. The procedures are often both done by oral surgeons and plastic surgeons. It seems like oral surgeons have a slight preference for a sliding genioplasty while plastic surgeons seem to perform implants, but there is no absolute, and either specialty could potentially do either of the procedures. In the end, the most important variable is finding a provider who has efficient schedule an experience to deliver, consistent quality outcomes.I suggest you have in person, consultations with both oral surgeons and plastic surgeons in your community. During each consultation, ask each provider to open up their portfolio and show you their entire collection of before, and after pictures of previous patients who had similar facial characteristics to your own. An experienced provider should have no difficulty showing you with the before and after pictures of at least 50 previous patients. Highly experienced surgeons should in fact have hundreds or preferably thousands of before and after pictures to choose from. Rather than focusing on which procedure is better, I suggest you focus your efforts on finding the best provider. In the end, finding the right surgeon is probably more important than which technique they use. Best, Mats Hagstrom, MD
