How will cauliflower ear affect my results? 1 year post op

If you had an otoplasty a year ago and you went back to sports like wrestling and bjj that causes cauliflower ear ( I’m wearing headgear all the time during the sports but still worried) does getting cauliflower ear effect the procedure even though it’s been a year? If cauliflower ear occurred am I allowed to drain it normally and will that affect the procedure (otoplasty)? If the ear keeps refilling after draining can I put magnets on the ear so that it doesn’t refill again?
