Reviewing hundreds of years of history, this chapter details the development of means of visualizing the larynx and the vocal folds, and explores how these technologies influenced theories of voice production. Key investigators in vocal physiology are discussed, and their contributions put into context with modern understandings of voice production. These leaders helped bring about the growth of the field of laryngology, which occurred in parallel with improvements in laryngeal imaging. The chapter tracks these developments, starting with Garcia’s laryngeal mirror, then continues through the rest of the nineteenth and twentieth centuries. Among the innovations described are the use of stroboscopy to study the opening and closing vibratory pattern in different vocal registers; the development and application in Groningen of videokymography to examine fast and irregular vibratory events; and the development of VoceVista, a non-invasive tool which combines electroglottography with acoustical information on the sung production.

Repetitive Trauma

Microvascular lesions, also called varices or capillary ectasias, in contrast to vocal fold polyps with telangiectatic vessels, are relatively small lesions arising from the microcirculation of the vocal fold. Varices are most commonly seen in female professional vocalists and may be secondary to repetitive trauma, hormonal variations, or repeated inflammation. Microvascular lesions may either be asymptomatic or cause frank dysphonia by interrupting the normal vibratory pattern, mass, or closure of the vocal folds. They may also lead to vocal fold hemorrhage, scarring, or polyp formation. Laryngovideostroboscopy is the key in determining the functional significance of vocal fold varices. Management of patients with a varix includes medical therapy, speech therapy, and occasionally surgical vaporization. Indications for surgery are recurrent hemorrhage, enlargement of the varix, development of a mass in conjunction with the varix or hemorrhage, and unacceptable dysphonia after maximal medical and speech therapy due to a functionally significant varix.

Subharmonic Frequency

This study observes in detail an F 0 /2 (sounding an octave below an original tone) subharmonic vibratory pattern produced in a normal larynx. Simultaneous electroglottographic and photoglottographic measurements reveal two different open phases within a subharmonic cycle—the first shorter with a simple shape, the second longer with a shape containing a “ripple.” Such parameters as the large open quotient (ca. 0.8) and the high airflow values (ca. 1000 cm 3 /s) distinguish this phonation from the vocal fry (pulse) register. Using an electronic divider to track the subharmonic frequency, a method has been developed to observe the subharmonic vibration of the vocal folds stroboscopically. The stroboscopic visualization reveals an unusual mucosal movement during the “ripple,” characterized by an opening movement of the upper margins, which interrupts the closing movement of the vocal folds. An explanation is offered that this vibratory pattern arises as a consequence of detuning of the usually identical frequencies of the dominant modes of the vocal folds, with 3:2 entrainment replacing the normal 1:1 pattern.
