Right side of face is fatter. What can I do? (photos)

In order to determine what potential cosmetic plastic surgery options could address facial asymmetry, it it imperative to look at the face in question. Please submit a picture of the face in question so Realself practitioners could see the problem. 

Hello, thank you for your question, maybe a picture would help us to evaluate your problem more accurately, however you must remember that facial symmetry is a very rare thing, most of us have some degree of facial assymetry, it involves also having more volume on one side of the face compared to the other. Sometimes the assymetry can be caused by muscle hypertrophy (having masseter muscle stronger from chewing only with one side or masseter contraction during sleep), sometimes the assymetry is congenital and theres not much you can do about it without surgery.
I suggest you visit a board certified plastic surgeon to determine the cause of the assymetry and that way you will be able to have a customized treatment. 
I hope you find this helpful, wish you the best 

Thanks for your question and Pictures
The buccal fat pad is a rounded mass of fat in the middle of your cheek. It’s located between facial muscles, in the hollow area beneath your cheekbone. The size of your buccal fat pads affects your face shape.
Everyone has buccal fat pads. However, the size of buccal fat pads can vary greatly.
If you have larger buccal fat pads, you might feel like your face is too round or full.
You can be a candidate for a Buccal Pad removal surgery.
Best of Luck
