1 month post otoplasty, should I continue to wear my headband at night? Does it shape my ears?

I had an otoplasty one month ago.The doctor told me to wear a light headband for one month especially at night.Here i am now..one month after surgery and i was wondering should i wear the headband for a bit longer at night or will my ears be ok at this point and there is no danger of hurting them while i sleep. Also does the headband contributes to the ear's shape or is it just the surgery?Thank you.
