Deep-plane Midface Lift for 31 Year Old Female?

From your post, I would turn you down to do this very difficult operation. Be careful in what you seek, because you may not achieve the result desired.

From MIAMI DR. B

As you have had 4 consultations, hopefully with qualified plastic surgeons with interest and focus in the face, you have come across 4 different approaches and opinions. The message is then, there are usually several ways to address an individual patients aesthetic concerns and goals. Generally, young patients in their 30's will benefit from mid-face volumization procedures with soft tissue fillers or cheek implants for malar volume and smile line correction, rather than more aggressive surgical repositioning operations.

However, there are hereditary conditions of poor mid-face development or sagging, where a mid-facelift procedure is a reasonable option and I have had young patients, albeit relatively few, who have benefited from such an operative approach over the years. Make sure you do your home work with a trusted specialist who has a good reputation. I would not recommend cosmetic surgery tourism and of course, never embark on a course of action based upon online information, seek a formal consultation.
