    A purely endoscopic neurosurgical procedure. Using this technique, both the optics and instruments are passed through a rigid, multiport chamber. This technique is ideal when performing surgery within the ventricular system using only a standard bur hole craniotomy.

    A: An anterior skull base meningioma of the planum sphenoidale to be resected with endoscope-controlled microsurgery. B: Unlike purely endoscopic surgery, in this case the endoscope is separate from the surgical instruments and functions as a light source, providing illumination near the region of interest. The base of the skull is first removed utilizing a small, elongated drill. C: The tumor is resected using microsurgical instruments with length and curvature specifically designed for the endonasal corridor.

    A: Standard 0°, 30°, 45°, and 70° angulated endoscopes used in endoscope-controlled microsurgery. The addition of high-definition optics has made endoscopic visualization comparable to microscopy. B: Instruments specifically designed for endoscope-controlled microsurgery, including malleable suctions (lower), angled micro-curettes and dissectors, and pistol-grip scissors (upper), have allowed surgical resection of regions previously visible only with the endoscope but not reachable with standard instruments.
