The most common method by far is an alloplastic implant
. These can be made of solid silicone
, porous polyethylene, eptfe, with silicone being the most common. Silicone chin augmentation is a relatively minor procedure that can be done under local, iv, or general anesthesia
. Limitations are few but might include the amount of augmentation is usually a maximum of about 10-12 mm. One "pro" would be the ability to change the size of the implant if needed or to even reverse the procedure completely. Risks include implant mobility, infection, numbness
, bone resorption
, and malposition--all are rare if placed by a well trained surgeon. Recovery time is 1 week or less. Sliding genioplasty
is a much more significant surgical procedure and is only performed under general anesthesia. It is usually thought of as irreversible but theoretically it could be done. There is a longer recovery--usually at least 2 weeks. It is much more painful since the bone is being cut and slid forward. Risks include infection, malposition, numbness and implant (screw/plate) mobility. In my opinion and my recommendation to almost all of my patients is the alloplastic implant. Good luck!
