Unusually small chin can be corrected in two ways: by augmentation using an alloplastic implant, and by so-called sliding genioplasty.
Sliding genioplasty is a surgical method that requires general anesthesia. It is performed by approaching through the mouth; it requires hospital stay and longer recovery and therefore, it is used very rarely.
Augmentation using an alloplastic implant is very frequent procedure in aesthetic surgery. Augmentation technique is comprised of an incision made under the chin, making a ’tissue pocket’ and placing a silicone implant. It is performed under local anesthesia or locally-potentiated anesthesia; it takes up to 30 minutes.
