This is a question I answered regarding a procedure done by another physician.
Numbness after a null is unavoidable and will get better in time. When you do a facelift, your skin has to be elevated to expose the structures that need lifting. This invariably will interrupt the nerves that bring sensation to your skin.
The nerves will take some time to regenerate as they grow at most 1mm a day in the best conditions but are hindered by infection, inflammation, age, genetics, health, nutrition etc.
One thing that could be considered is that a larger nerve is caught by the sutures which is rare and eventually will also recover in most instances. But rarely can require removing the suture and redone.
