LARYNGEAL surgery requiring utilization of the operating microscope has led to the development of several new laryngoscopes. The new instrument reported here permits microscopic laryngeal surgery and consists of a simple right-angle tubular handle to which a standard laryngoscope support can be easily attached (Figure). The blade is a large oval tube similar to other laryngeal instruments. The tip is elevated, giving it characteristics desirable in an anterior commissure instrument; the width of the tip, however, is greater and the shape flatter than that of the usual anterior commissure laryngoscope. The distal one third of the blade is open, allowing full visualization of the posterior and lateral walls of the hypopharynx as well as of the larynx. The proximal portion of the blade is an oval tube which allows binocular vision. It differs from other instruments by having slots on each side to allow easy insertion of instruments, particularly when
