A method is described in which an open neurosurgical target is pre-operatively marked on the skull of a patient. A target point of the scalp surface localized from neuroimaging studies is transferred onto the skull by an injection of pyoktanin blue. Its accuracy and reliability is far superior than that of the usual scalp marking. The method is simple, practical, and allows a smaller, regional craniotomy with the advantage of minimum operative invasiveness.
