STEREOTACTIC AND FUNCTIONAL NEUROSURGERY
A Contemporary Definition by Members of the WSSFN and ESSFN
Stereotactic surgery dates back to 1908, one century ago, when Sir Victor Horsley and Robert Clarke introduced their new apparatus to insert a probe or needle under accurate control into subcortical stuctures in an experimental animal model.
The deﬁnition of Stereotactic and Functional Neurosurgery was debated formally for the ﬁrst time, in 1973 during the ﬁrst meeting of the World Society for Stereotactic and Functional Neurosurgery (Philip L. Gildenberg). Since this period, general neurosurgery has made great progress inﬂuenced by new technical developments (minimal-invasive surgery, image-guided surgery, neuronavigation, radiosurgery, frarneless brain biopsy, etc).
On the other hand, many particular topics remained within the frame of the special ﬁeld of stereotactic and functional neurosurgery (for example movement disorders surgery, pain surgery, CNS drug-infusion, cell therqay, etc). Within this context an appropriate contemporary deﬁnition of Stereotactic and Functional Neursurgery is sougit for. The following deﬁnition is a synthesis and a consense after discussion among a group of experts.
2. A Contemporary Deﬁnition
Synthesis of propositions from A. Lozano, M. Hariz, P. L. Gildenberg, J. K. Krauss, S. Blond, G. Broggi, and Y. Lazorthes Stereotactic and Functional Neurosurgery is a branch of neurosurgery that utilizes dedited structural and functional neuroimaging to identify and target discrete areas of the brain and to perform speciﬁc interventions (for example ablation, neurostimulation, neuromodulation, neurotransplantation, and others) using dedicated instruments and machinery in order to relieve a variety of symptoms of neurological and other disorders and to improve function of both the structurally normal and abnormal nervous system.
