There are a lot more knowledgeable people on this forum than I, but from what I have read I would leave it be and monitor the healing over this growing season before making any rash decisions. As to the pruning advice, we would need a little more info. What is your goal for the tree? How tall do you want it? What rootstock is it on? Are you now going to cage the trees or do you plan on letting them grow tall enough to avoid future deer brows? Etc. etc.
There are also some really handy pruning guides on this forum if you do a search. Good luck!
