Is there anything I can do to help regain mandibular nerve after Kybella paralysis of nerve?

The paralysis should wear off with time as the nerve begins to regain it's function. This should take a few months, but won't be permanent.  you can try RF treatments like venus legacy and exilis ultra with steroids and neurontin to speed up the healing.  LED may also help.  Best, Dr. Emer

unfortunately it will just take time for things to come back. You can speak to your doctor about using a little botox on the opposite side to help with symmetry. 

Thank you for your question. The good news, I am not aware of any cases of permanent nerve damage from Kybella. All the cases reported have been temporary. There is probably no definitive way to improve nerve healing. However, I would recomend dally exercises of attemtping to purse your lips as if trying to give a kiss. This will get any part of the muscle that is still working to help recruit the remainder of the muscle that is affected. Good luck.
