FAQ
ASO + Genioplasty — frequently asked questions
How much longer does surgery take when chin surgery is added?
ASO typically takes about an hour; adding genioplasty usually adds 20–30 minutes.
Why combine ASO with genioplasty?
Setting the lips back can make a weak chin more noticeable. Adjusting the chin at the same time balances the whole lower face.
Is there a visible scar?
Both procedures are performed through incisions inside the mouth, so there are no visible external scars.
