Numbness and Swelling Post-chin Implant, Neck Lift, and Lower Facelift

If you continue to have unilateral numbness 1 year after the procedure, you should discuss this with your surgeon.
There are two major nerves that can be effected by chin augmentation and neck surgery. One is a motor nerve that is typically injured/bruised from the liposuction and typically accompanies chin augmentation; The other is a nerve coming directly out of the jaw bone, which provides feeling to the lower lip. There is one on both sides.
Therefore, if you have relatively symmetric numbness pain and tingling, this is most likely due to swelling and stretching of the nerve. It is likely to return because it would be very unlikely that both nerves were damaged. If you have profound numbness on one side to the point you are drooling and unable to "feel" you lower lip, I would be slightly more concerned but nevertheless, your nerve could still recover.
You should always keep an open dialogue with your surgeon and express your concerns.
I hope this helps.

Numbness or muscle weakness following a #facelift and other facial procedures is not uncommon.  When the skin is separated from the underlying tissues during #surgery, small sensory nerves are cut. Varying degrees of #numbness will be present after surgery and will improve gradually as the nerves reconnect to the skin. This process can take from 2-6 months for face, neck and cheeks, and to 9-12 months for the forehead and scalp. Muscle #weakness may also be present around the mouth especially if liposuction is used. This typically recovers fully in the months after surgery. If you have certain concerns about the procedures and #healing process, it is recommended to call your board-certified surgeon or their medical staff and discuss those #concerns.

Numbness of the lower lip area after a chin implant is very suggestive of inflammation of or injury to the mental nerve (the sensory nerve of the lower jaw and lip area).  I would remove the implant with the purpose of allowing the nerve to recover.  Sensory nerves are very resilient and recover with much greater predictability than motor nerves.
