This report describes a newly developed endoscopicimage display system which is mounted on the optical unit of the surgical microscope. This system permits the neurosurgeon to watch the endoscopic image through one of the eye lenses of a surgical microscope during application of neurosurgical endoscopy under open microsurgical procedures. It frees the neurosurgeon from the major conventional inconvenience that he has to discontinue watching the microscopic view in order to look at the endoscopic images through the ocular of the endoscope or on the video monitor.
