Use of the operating microscope for indirect microlaryngoscopy in routine office practice has been broadened by the development of a supplementary system which offers indirect microlaryngostroboscopy as a practical tool for routine laryngological practice. The supplementary system has been adapted to the Zeiss operating microscope equipped with a 300 mm objective. The original light source on the microscope is replaced by a stroboscopic bulb which flashes in synchrony with the output of an audible tone generator. The tone generator is used to guide the patient's vocalization during the examination, and, thereby, produces a stop‐action image of the vocal cords. Its use in conjunction with clinical judgment by the examiner can aid in the diagnosis and treatment of various dysfunctions of the vocal cords.
