Abstract
The authors, each with 40 years of experience in laryngology, aim to lay out the general principles and details of a systematic method of direct laryngoscopy for adults, children, and infants. Advances in laryngoscope design and application, advantages of telescopes, use of the operating microscope, and principles of modern anesthesia are highlighted. Particular reference is made to classification of laryngoscopes, advantages of Lindholm laryngoscopes, suspension laryngoscopy, the principles of biopsy, and problems of laryngoscopy. The difficult airway and the obstructed airway are discussed in detail. With the recent renewed interest in investigation and treatment of laryngeal problems and a better understanding of laryngeal physiology and voice production, the future will, no doubt, see new procedures to treat and restore laryngeal function. The fundamentals in this report form a basis for direct laryngoscopy, endolaryngeal microsurgery, laser surgery, and phonosurgery.
