Efficacy of three-dimensional (3D) endoscopy for evaluation of ventral skull base pathology has been reported in several studies, in addition to being recently reviewed in World Neurosurgery (Zaidi et al., 86:419-413, 2016). The clinical significance of 3D endoscopy is conventionally discussed with the assumption that the stereoscopic effect is constant among various 3D techniques. However, we would like to stress that the stereoscopic effect varies according to the integrated 3D technology, which can affect the surgical performance of 3D endoscopy. In the present study, we report our clinical experience of dual optical channel 3D high-definition neuroendoscopy and discuss its clinical significance. In addition, we review how depth perception is obtained during endoscopic surgery to gain a better understanding of the efficacy of 3D endoscopic surgery, which has rarely been discussed in studies involving 3D endoscopic endonasal surgery.
