Answer: If you are sure the top of the tree is dead, cutting it off will give the new sprout a chance to grow into a new tree. Cut back the branches on the top of the tree and look for live tissue - it will be green in the middle of the cut. If there's green, that branch is still alive, as is the trunk. If the tissue is brown, that branch is dead. Keep cutting back until you find green tissue. If you can't find any, the entire top of the tree is dead and you can prune it off. Best wishes with maple!
