Boxing after long time otoplasty?

I had an otoplasty surgery 14 months ago. Now, i want to start boxing. It's possible with my training and learning how to box, i will start to be punched after 5-6 months forthcoming period. Can it be a problem for my ears to be punched ? If it's a problem, Can I fix this problem with wearing boxing head guard or the damage can still hit the ears with this head guard ?
