Reversing an endoscopic mid-facelift - Is it possible?

Needless to say, photos would be of benefit. How your surgeon suspended the midface would also be helpful to know. I think that an endoscopic midface lift in your 20's may have been a bit aggressive but dropping the midface can likely be achieved intraorally via a subperiosteal dissection of the midface tissue. Not terribly complicated. Over time, your mid face will also fall to its original position.

You should be seen and evaluated in person by a plastic surgeon for your concerns. It is theoretically possible to release the midface and resuspend it lower, but this should be done with extreme caution to avoid traction on the lower eyelid (among other potential problems). A safer approach might be to just address the symptoms you have now, as you will lose fat in your midface with time and the problem may ultimately solve itself, but this all hinges on physical examination and a specific discussion of the issues you are having.
