If I don't wear a headband would that impact how much they protrude?

I have done otoplasty for almost 3 week, only for my left ear. I wear headband for the first 2 week. But now i only tape the bandage to my ear. I notice the ear is protruding more than my first week. Does the headband affect anything about it, if I wear the headband tighter would that impact how much they protrude? Please helpp!!
