Is numbness and tightness typical after after a lower face and neck lift? How long will this last?

Numbness or muscle weakness following a #facelift 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.
As the nerves regenerate, the itching, burning, tingling and shooting #sensations will occur. Ice, moisturizers and gentle #massaging are helpful during this phase of the #healing process. Frequently there is a tight feeling in the neck, jawline and cheek after a facelift. During surgery, not only the skin but the underlying muscles are tightened to create a better and longer lasting result. Additionally, the #swelling will move downward in the first week and the neck will feel even tighter. Do not be alarmed: the sensation will decrease during the first month. 
Some degree of firmness or lumpiness under the skin is normal after surgery and will resolve with time. Local #massage of the areas may accelerate the resolution of this problem, which normally takes 2-4 months to disappear completely.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.

Everything you describe is normal following these procedures except possibly the inability to pronounce certain things. Your plastic surgeon can let you know if this is normal based on his exam.Numbness resolves in the first yearTightness much sooner usually in a few months

Tightness and numbness after a lower facelift and neck lift is common immediately
post op and may last several days to weeks. The length of the symptoms depends
on the surgical technique used and the healing process of each patient. Usually
the tightness improves faster than the numbness. Patient should discuss these
symptoms concerns with their primary surgeon so he/she could guide the patient
during the healing process

At this point, numbness and tightness are very common. Most people will feel numbness around or in front of the ears temporarily. If this does not continue to improve, you should present this question to your surgeon to gain their insight. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

It is not unusual to be very numb after a lower facelift/neck lift surgery. The numbness is nearly always temporary and you should expect full recovery over time. The amount of time, however, can be variable. Nevertheless, within a couple of weeks the numbness will stop bothering you, even before you recover any sensation.Tightness is also a normal feeling, especially along the neck and jawline. This will also subside overtime.I would encourage you to discuss this concerns with your surgeon, but seems to me that this is a normal postoperative course.
