Cheeks are sagging after jaw surgery and missing teeth. What is the best solution? Is facelift or botox an option? (Photos)

What is not corrected by this can be improved with hyaluronic acid fillers.  They will last over a year and can be easily adjusted if there is ever a problem.  That can't be said with the "permanent fillers" and grafted fat.

If you feel that your face does not reflect how young you feel on the inside, a facelift may be the solution to help you look and feel younger. During your consultation, your doctor will evaluate your skin texture and elasticity, as well as your underlying skin structure and your facial bone structure. Based on this evaluation, he/she will create a custom surgical plan, detailing specific techniques and recommendations to meet your goals. Your doctor should make sure you have a full understanding of what results to expect.Always insist on a board certified surgeon!
