Will has my normal smile returned after neck and face lift? I am post 9 weeks.

Your smile should not change with a facelift. You should check with your surgeon to make sure that there is no nerve damage to the muscles that allow you to smile.

Although the muscles of the face function normally there manifestations on facial expression are buffered by swelling. They may not appear to be completely normal until the swelling is totally resolved.

There is a nerve down by the chin which innervates the muscles which pull down the lower lip.  During a facelift, the nerve may experience some trauma, and will not work correctly for a while.  When this occurs, you won't be able to pull down the corners of your mouth and the lip will stay up over the teeth when you smile.  This occurs most commonly after liposuction of the jowls - don't know if you had that done.  The nerve should slowly recover and your smile should return to normal, but this can take up to 6 months.
