2 years post- op facelift. Is it possible to get a mid face and neck lift without causing anymore nerve damage? (Photo)

Thank you for your enquiry. I am sorry to hear that you have experienced problems with your facelift.
Although it is not possible to say that surgery around the face and neck has zero risk of Nerf damage, some interventions are associated with lower risk levels.
The neck lift intervention in your situation, would most likely require the deep plane approach as your surgeon has most likely already tried to improve the appearance of the neck with a more limited approach.
For the appearance of the face, a mid – face lift may not deliver your expected results, as it does not tend to help the marionette lines.

The version of facelift that tends to be more effective at controlling laxity in the lower face and also absorbs some of the skin excess under the chin is the one where the scars extend in front of the hairline in the temple region. It allows a more effective reduction of the skin excess. it can be carried out in association with tightening of the SMAS or a deep plane approach, which you would probably want to avoid, but the vertical vector is the most relevant contribution.

Finally, the mid face lift is typically carried out deep to the level of the facial nerve branches and should allow a safe intervention

First off, your face dropping and nerve damage were not the result of not "doing your neck." Yes, it is possible to revise your face and neck to reshape your cheeks and fix the laxity and banding in your neck. I would also recommend targeted facial fat grafting. While there is always some risk with any surgery, this can be done quite safely by a well-trained surgeon with good technique.

I would recommend a revisionary face/necklift. The deeper structures of the neck need to be repaired appropriately as the central depression is from over-resection of fat and inadequate repair of the platysma muscle bellies in the midline. I would also recommend redraping the face and removing some of the redundant skin. It is very important to find a well-trained actual plastic surgeon (not a "facial plastic").
