After liposuction alone you can get this type of lip movement asymmetry. Many times it may not be due to a nerve injury but an injury of the muscle. There are multiple muscles that help to pull the lower lip down. Both types of injury are self healing and would be expected to have a complete recovery. The fact that you had a chin implant might slow down the healing because of more swelling.
After 6 to 8 weeks would expect to see some improvement but it will still take several more months to get back to normal.
Normal lip function should return
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.
Lip movement after chin augmentation liposuction
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.
Paralysis should be temporary
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.
Marginal mandibular branch of the facial nerve injury
You probably have an injury to the marginal mandibular branch of the facial nerve. The vast majority of the nerve injuries are temporary and will recover over time. If you have any slight movement to your right lower lip, that is a good sign. If it is completely paralyzed at this time, it still may recover but the possibility of permanent injury is present. The 1 mm. per day rule applies to nerve injuries that do not involve transection of nerves and refers to how quickly a nerve can repair itself. Since you did not have open surgery, the chance of clean transection of the nerve and thus of repairing it surgically is highly unlikely, although needle sticks can potential transect or injury small nerves. Avulsion of the nerve with the vacuum of the liposuction is possible and would be impossible to surgically repair. Hopefullly it is just bruised or contused and repair within the nerve itself will just take time.
Lip asymmetry after chin implant and lipo
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.
Give paralysis 6 to 8 weeks to subside
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!
Marginal Mandibular Nerve Palsy
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.
Paralyzed Lip After Neck Lipo and Chin Implant
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 should be self limited
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.
