Contemporary methodology of stereotactic neurosurgery

A survey of stereotactic operations from neurosurgical centres, one in Madras and the other in Bratislava, shows that many stereotactic operations are of the combined type. From a methodological viewpoint, stereotactic preformances may be divided into simultaneous, successive, symmetrical, asymmetrical, and one-sided, respectively. Thus, the stereotactic operation differs from the traditional concept that the patient may be cured by a single surgical performance. The stereotactic treatment usually consists of a succession of tactical steps, which make up the strategy of the whole treatment.
