Facial Lipo Damage Not Getting Better After 8-weeks?

Nerve recovery can take up to two years before one has to accept a  (permanent) nerve deficit. Most likely your facial nerve branch was bruised by the liposuction and needs to (spontaneously) recover.

Observation and patience are the treatment of choice. Maybe your Plastic Surgeon wants to send you to a Neurologist for a consultation and nerve studies. This studies very often can give you and your Surgeon a better idea about the time needed for the nerve branch to recover and what your chances are for complete recovery of the Nerve.

Good luck and lots of patience!

Your nerve will come back almost certain.  I am not a fan of Smart Lipo.  Possible the laser heated the nerve and it just needs to grow back.  Nerves such as this can be out up to a year but large series of study including my own indicate they nearly all return.   Mar McGregor, MD  studied many  nerve injuries and found 100% came back in a year.   In 30 years I have had a few go out but all returned.  My longest wait was 4 months.  In 30 years I had some weaknesses for a week or two and that is rare but we see it.   All came back.  I believe your nerve will regenerate.  After injury the nerve hibernates for 4 weeks and then starts regenerating.  Be patient.   Wait with patience is all you can really do.  My Best,  Dr C
