Paper Abstract

A unit is presented that provides the neurosurgeon with CT, MRI, x-ray, DA, and DSA compatible headholder and multimodality image localization as well as freedom of choice for surgical approach on patient's intraoperative positioning. The unit consists of a carbon fiber ring-shaped headholder which allows free selection for location of three or four fixation pins, avoiding interference with the flap sites or craniotomy. The base ring is mounted intraoperatively on a special adapter that allows any patient positioning including supine, lateral, prone, 3/4 prone, sitting, etc. Surgical draping can be performed given a completely sterile field. An arc/quadrant localizing device can be mounted on any four alternative positions according to the neurosurgeon's preference. A PC compatible software gives the setting for any possible mounting. Intraoperative the localizing unit can be used in a 'fixed' permanent setting or as a 'non-fixed' system to provide intraoperative three-dimensional orientation. Different are adapted instruments which give the unit further capabilities, especially 'bayonet' type brain retractors (cylinders and speculum) that allows the neurosurgeon to keep the surgical corridor unobstructed from the arc. As an alternative, in the 'non-fixed' setting, self-retaining arms are fixed to the base ring and brain retractors and conventional microsurgical technique can be used without any mechanical obstruction. This article presents the unit details, methodology and the clinical experience in 103 consecutive cases of 'open stereotaxis' for resection or internal decompression of deep seated or near eloquent area lesions.
