Any suggestions on bulge of fat/muscle in front of ear? (photos)

I have a strange bulging of fat and muscle on my right side that completely blocks my ear from the front. Bigger when jaw clenched and ear relaxed (if I perk my ear up it decreases the bulge). My masseter muscle isn't excessively large. I have had 3 Le-Fort surgeries but I vaguely remember this problem before, so am doubtful it is related. I have no idea what is causing this or how to treat it. All opinions welcome, thank you for your time! :)
