Paralyzed Lip After Neck Lipo and Chin Implant

There are two major nerves that can be effected by chin augmentation.
One is a motor nerve that is typically injured/bruised from the liposuction (as mentioned by Dr. Yuan) and typically accompanies chin augmentation. Injury will result in the appearance you demonstrate in the picture. Liposuction will bruise the nerve temporarily with expected recovery, whereas surgery such as a facelift may actually cut the nerve, in which case recovery may not be possible. This does not seem to be the case in your specific instance.
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. Injury to this will cause numbness and tingling in the lower lip but should not effect the movement of it.
You should always keep an open dialogue with your surgeon and express your concerns.
I hope this helps.

I agree with all the other surgeons that this should be a temporary loss of function. The nerve during liposuction usually is not "cut" but injured to the point where it does not function. You should see slow improvement over 6-8 weeks, full recovery in several months.

This type of nerve paresis (or weakness) can occur after liposuction alone or with a chin implant. It could also be a muscle injury as well. It usually comes back with time but may be a month or longer.

This type of injury will typically correct itself over time - usually within 3 months or so.  Some believe that continuing to try to move the paralyzed side may help speed up recovery.

Most likely, the facial nerve branch innervating the right lip (a.k.a. marginal mandibular nerve) has been stretched or bruised. Unless the nerve is transected, function usually returns to normal. Given the procedures you had, I think that it is unlikely that the nerve has been cut - your surgeon can give you some additional insight into this.
After 6 or 8 weeks, you may see a return of the muscle function. It will be slow, not overnight. I understand that this is stressful for you! Certainly, you want to stay in close contact with your surgeon.
Best of luck for fast recovery!

First, there is no question about the paralysis being there now. It should return slowly over a period of weeks to months, so you have to be patient. Sometimes the first signs of recovery are tingling and twitching. Then you start getting slight motion and each week a little more. If it was caused by swelling it will recover faster. You might try ultrasound treatments for swelling though this may not help. I know this is most stressful, but try to be patient and see you doctor frequently for follow up.

The nerve that moves the lower lip is called the marginal mandibular branch of the facial nerve. If this nerve is injured you can get temporary or permanent weakness of the lower lip. This nerve is more at risk with the liposuction than the chin implant. Since these two procedures are often down together, it is good to know this risk. It is rare if proper and careful technique is used and is often temporary if it occurs. It can take several weeks before return of full function.

Marginal mandibular nerve dysfunction is not uncommon after face and neck liposuction, particularly if the face gets very swollen.  Swelling pressure on the nerve can temporarily choke the nerve and cause nerve dysfunction.  Although this is temporary, it can last from 3 weeks to 3 months and slowly begins to recover.  

Your likely have an injury to the marginal mandibular branch of the facial nerve.  It is unlikely that this nerve was transected during your surgery.  If the nerve was just "bruised" it should recover with time.  If there is concern, or if you would like a definitive answer, you could pursue electromyography to determine if you have an intact nerve.  Best wishes.

On a rare occasion, a paralysis of the lower lip functioning muscle known as the marginal mandibular nerve can be bruised or stretched. Simple liposuction of the neck bruised the nerve, traumatized it, but did not sever the nerve. The nerve should come back in approximately eight to twelve weeks to normal lip function.
