Techniques in microlaryngoscopic photography.

A microlaryngoscopic photographic technique is described similar to that technique advocated by Kleinsasser. This technique is an uncomplicated routine method, which can be adopted by anyone using the Zeiss surgical microscope. With a relaxed, intubated patient, alignment of the optical axis of the microscope with the central axis of the laryngoscope, and with careful focusing, using the over-changed (9.5 A, 7.6 V) 6 V 50 W bulb, shutter at 22, magnification of 16 or 25, and with 1/4 second exposure time, and the Kodak Ektachrome HS film (125 ASA), the result should be satisfactory.
