Abstract
A laryngoscope, for use with a binocular operating microscope, has a tube with a flared distal end and a narrow intermediate portion allowing manipulation of the tube. The proximal end of the tube is flared horizontally to an extent such that the centerlines of both objective lenses of the microscope enter the proximal opening of the tube even when the microscope is moved to the left and right to view portions of the larynx spaced laterally from the central axis of the tube. When the microscope is moved laterally, the centerline of one of the lenses intersects the interior wall of the tube, which is dark. Therefore the annoying effect of seeing objects external to the laryngoscope tube with one eye is avoided.
