How long does it take for complete healing from chin lipo? I am very concerned about a crooked smile (Photo)

Swelling typically takes 2 months to resolve, the hard and lumpy feeling usually 4 months or so-sometimes up to 6 months.  The injury to the marginal mandibular nerve is a rare complication and can be  be permanent.  Try to pay attention to the movement on your mouth every couple weeks, even if you are getting slow improvement that is a good sign that the function will return.  The injured nerve can take 6-12 months to recover, if it does.  Good luck, Jane. 

You have a left marginal mandibular nerve palsy.  Translation: the nerve that controls the left lower lip isn't working properly.  This is highly likely to resolve with time, though oral steroids may be useful in speeding up the process.  I have definitely seen these problems, and none has ever been permanent.
