Is addind vertical length to chin in sliding genioplasty riskier?
Producing up to a modest amount of increased chin height during sliding genioplasty shouldn't be any riskier than normal. There are limits to how much vertical lengthening can be done using your own bone so definitely check with your surgeon too.
