Right side of the lip doesnt go down when smiling or talking or laughing after chin implant removal? Crooked smile? permanent?

It is quite possible that you have temporary loss of sensation and muscle weakness after chin surgery. Retraction of cheek, lip and other soft tissue during surgery and blunt trauma is usually the most frequent cause of this complication. Injuries of this nature would recover within 4 weeks to 6 months depending of the extent of injury, swelling, age, etc. Very few may turn into permanent loss. Be patient and stay in touch with your surgeon. Good luck.

You sound like you have numbness to your lip as a result of injury to your mental nerve.  This typically resolves over days to weeks.  In rare situations numbness can be long lasting but less severe over time.  Regarding lip asymmetry this can result from damage to the depressor muscle of the lower lip.  This can occur but  usually resolves over time.
