Droopy Eye After Mid Face Lift

The midface lift attempts to lift the fat of the cheeks through an incision usually for lower eyelid surgery only.  In releasing a ligament (arcus marginalis), a strict anatomic barrier between the lower lid and the cheek converts the lid and cheek into one anatomic unit.  If there is any loss of support for the repositioned cheek, the lid falls with it.  It's somewhat hard to fix.

The fact that this question is being asked in this forum indicates that you do not enjoy very good communication with your surgeon.  If a doctor was suggesting to me that I have surgery in 12 days, I'd want to know why, what's the diagnosis, what is the procedure expected to accomplish, what are the risks and expectations.  You must find these things out.  The eye complaints may be facial nerve related.  

The dissection during a midface lift is in the area of nerves that supply the muscles around the eye. Normally, the surgery occurs in a different plane, so the nerves aren't cut, but stretching or cautery can rarely cause temporary injury. It's hard to comment about the upcoming surgery without knowing what is being planned exactly. Usually, it is more a matter of time for the nerves to heal (presuming they're not cut).
