Which procedure should I consider in combination with otoplasty for Plagiocephaly? (photos)

Hello everyone, i want to ask about surgery about plagiocephaly it really concerns me mentally, i really dont know what it needed and i hear a lot of mixed opinions about this topic if it can or cannot be improved for sure ill hit otoplasty but i dont know what else, i prefer my smaller side but i dont know what are the chances for improvement, thanks everyone
