Stabilization and manipulation of instruments in endoscopic neurosurgery has traditionally
been a manual task. Conventional self-retaining retractors have failed to provide
reliable fixation for endoscopic procedures. Most surgeons rely on a team approach
to endoscopy with one individual controlling the endoscope while the other manipulates
instruments within the field of view. This two-surgeon approach is manpower intensive
and not an option at many facilities. Recently developed technology provides the independent
practitioner with another option. Several nitrogen-powered stabilizing arms have been
introduced which decrease or eliminate problems with post-positioning drift. To facilitate
fine maneuvering of the endoscope, a new positioning arm is available with an incorporated
microdriver capable of sub-millimeter adjustments. We present an illustrative case
of the utility of this device in selected endoscopic procedures.
