Microscopic laryngology: Teaching techniques

Microscopic laryngoscopy can augment the skills of the laryngologist by adding increased magnification, depth perception and bimanual micromanipulation during direct laryngoscopy. By interfacing the Zeiss operating microscope to a low‐light‐sensitive high‐resolution color television camera, via a fiberoptic bundle, the surgeon may operate and teach, unencumbered by the addition of television equipment. This unique capability enhances the teaching of laryngology by:1 Crystallizing the three‐dimensional anatomical visual image of the student. 2 Allowing appreciation of the dynamic laryngeal view during direct laryngoscopy. 3 Demonstrating the fine, accurate maneuvers of laryngeal instruments. 4 Allowing the instructor to monitor visually the surgical actions of the novice, advising and directing his manipulations, while allowing the student to gain personal surgical skills and confidence. 5 Demonstrating laryngeal lesions and surgery to an unlimited audience. 6 Recording on color videotape, laryngeal anatomy, lesions and surgery.
