Use of traditional two-dimensional (2-D) neuroendoscopy is limited by lack of depth perception. The advent of next-generation three-dimensional (3-D) endoscopes potentially compensates for this limitation. The aim of this study was to objectively compare the 2 modalities in a controlled laboratory environment. ⋯ Our data do not support the superiority of the 3-D endoscope over its conventional 2-D congener, although its use may shorten the learning curve associated with neuroendoscopy, regardless of subjects' prior experience with neuroendoscopy.
