Following my facelift surgery 2 years ago, my bite is severely off and my face swells. What sort of doctor should I see?

I had a facelift, 2 years ago .Following surgery the swelling was extreme and even now my face swells and is numb on one side. Worst of all,since surgery, my bite is completely off and I have difficulty chewing & smiling .I am not even sure what sort of Dr to see or where to begin. I also have trouble turning head fully.I have tried talking to Dr and he said to give time and is evasive and takes months to get appt.He is well known but not helpful.Have you heard of bite issues w/ lift b4?
