Also doctor Palmer you said that you have: “found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty”. you recommend removing the excess skin at the time if implant removal. Could this same procedure be done at a different time? Is it as effective and long term as a genioplasty? What are the risks of a genioplasty? Thanks Jeannnn
