What is this dent on one side of my cheek called & how to minimize it?

I’m not a big fan of this procedure because it tends to lead to premature facial aging down the road when facial fat and volume becomes somewhat of a premium.
It’s a little bit difficult to restore the volume after buccal fat has been removed.
Fillers are temporary, but probably more predictable. Fat transfer may also be an option, but it is less precise and less predictable.
Good luck,
