Chances are your cheekbone will probably not equal out. Has this inequality always been present? Is there any pain involved. Just making sure it's not some sort of abcess, just normal feature asymmetry. If this is slight, most likely it is just that. Many people have eyes or ears that are not of equal size, one nostril larger than another etc. Personally, I have a similar feature as yourself. One cheekbone is more defined than the other. It is a minor asymmetry and just makes for a "better side".
