Can boxing ‘undo’ the otoplasty surgery after 8 months of rest?

After Otoplasty and having at least 8 months rest, I was wondering if I will be risking undoing the procedure if I go back to my sport of choice, boxing. I know this sport poses a threat to untouched ears initially but with the similair risks of untouched and post-procedure ears aside, is there any more risks that I should know about/ be careful of? Can this sport ‘undo’ the procedure or only give me the same risks I already had pre-surgery? Thanks for the time and hope this can be understood.
