Stereotactically-Guided Microsurgical Resection of Deep-Seated Brain Lesions: Minimization of Established and Development of New Unconventional Approaches

Abstract

Since April 1987 we have operated upon 209 patients with deep-seated or subcortically located lesions of differing etiology utilizing stereotactical microresection techniques in conjunction with the Dortmunder microstereotactic device. By means of these techniques the size and subsequent trauma of established surgical approaches were minimized; the approaches could be chosen more selectively according to lesion-situs and the functional topographic-anatomic considerations enroute; additionally, new, unconventional, transparenchymal, low-trauma approaches were adopted. A survey of our concept of minimal invasive neurosurgery stemming from the utilization of stereotactic microresection techniques with approach optimization and modification is presented.
