Genioplasty (chin surgery) in Korea - sliding vs implant?

Both work well; the choice depends on how much projection you need and your priorities. A chin implant (usually silicone/Medpor) is simpler, has shorter recovery, and suits mild-to-moderate horizontal deficiency, but carries small long-term risks of shifting or bone resorption. Sliding genioplasty cuts and advances your own chin bone — it avoids any implant, can correct height and asymmetry as well as projection, and is very stable long-term, at the cost of a more involved recovery. For a moderate increase, an implant is a reasonable, lower-recovery option, while genioplasty is preferred for larger moves or vertical/asymmetry issues. Korean surgeons are skilled in both.

This is general information — an in-person consultation with a board-certified specialist is the only way to get advice tailored to your anatomy and goals.
