title: Endoscope-assisted image-guided approach to the pituitary gland: preliminary cadaveric study.
abstract: The microscopic transsphenoidal approach to the pituitary gland is the current standard technique used by neurosurgeons to operate the pituitary gland. The endoscopic transsphenoidal approach to the pituitary gland is a current trend because more neurosurgeons are becoming familiar with the use of endoscopes. The use of associated image-guided surgery (or surgical navigation technology; these names are equivalent and are used interchangeably) allows a precise approach that increases the safety and efficacy of a surgical procedure. The InstaTrack system (GE Medical Systems Navigation and Visualization, Inc., Lawrence, MA) is a frameless electromagnetic navigational system used in this study. The objectives of this preliminary and conceptual cadaveric study (three heads) are to get familiarized with the use of image guidance and the study of the endoscopic anatomy of this region and to investigate the technical requirements and benefits of possible future shifting from microscopic towards endoscopic image guidance.
