PS: what do you mean with "best possible conditions"?

well when a person is decapitated they die because the brain is no longer supplied with nutrients and oxygen.however its been found that the brain doesnt die immediately after the head is severed.and can live for a really short period (usually a few minutes)before damage.the exact period varies by person.after which tissue starts dying eventually leading to brain death.however as shown in the treatment of stroke,if blood supply is regained quickly enough,damage can be minimised. in the case of a severed head,while its impossible to heal nerves veins and arteries fast enough to save the brain via any kind of surgery.but if we consider people like naruto or tsunade with hundred healings ,their bodies are able to heal themselves at a remarkable rate without conscious effort.in theory if their heads were cut off but still in contact with the body,within minutes their bodies would begin to regenerate tissue and completely rejoin the head to the body with minimum brain damage if done fast enough,thereby surviving decapitation. kinda crazy but possible in a best case scenario.the head would have to be cut off cleanly with surgical precision and kept in contact with the body.
