Conclusion and possible future trends.

No technology will continue unchanged indefinitely. The Gamma Knife Perfexion sets a gold standard today, but at some unspecified future date, new ideas will emerge, though none seem to be likely in the short term. The treatment of neurosurgical conditions today cannot be sensibly undertaken by single practitioners. Teams, consisting of members with the appropriate expertise, are required to meet and discuss and agree on patient treatment that is then allocated to one or other members of the group. Conflicts will always arise but their effects can be minimized by the use of treatment teams and awareness of past conflicts and their speedy discharge into wastebasket of medical amnesia.
