If it is that large of an incision, he may have two drains. Though usually one drain is used. It varies from case to case. His head will most likely be bandaged, in order to keep the incision line clean. I don't see any reason as to them having to shave the whole head, but I really am not sure about that. You can try asking Dr. Levitin on the ask the expert part of this website. He has been very helpful with all of the question I have had. Hope all goes well. Good Luck. Hugs.
