My Lower Lip Looks Like Popeye's After Neck Lift.

It almost appears from the photos that you had a chin implant inserted?  If you did then the function should reutnr earlier than later ie within a few weeks as it is muscular in origin. 

 

If no chin implant then it is likely that there is some injury to the facial nerve that moves the lower lip downward.  This could be in the form of swelling and irritation of the nerve or more unlikely the nerve could have been inadvertently cut during the dissection.  Hopefully that is not the case, but if it is then you may require months to regain some of the function.  Fortunately for all of the other readers out there and a message to your friends ..... this type of problem is  exceedingly rare.  I wish you the best as you recover.

Unfortunately you have suffered an injury to a branch of the facial nerve that runs just beneath the jawline. Hopefully the nerve was only stretched, not cut --you can expect full recovery if the nerve was only injured without being cut. It may take months.

 

The swelling indicates that you probably had more oozing of blood on that side--common, and should not effect the overall outcome of your surgery. Continue careful wound care to the scab and be sure to visit your surgery as often as necessary until the wounds are healed.

Good luck!
