In this paper, I will provide an update on work published in the past 2 years on endoscopic laryngeal imaging techniques including stroboscopy, high-speed digital imaging, and videokymography. There is increasing evidence in the literature from the past 2 years on the clinical usefulness of high-speed digital imaging and kymography as an adjunct to stroboscopy to understand the pathophysiology of hoarseness. The evidence is particularly strong in cases with moderate-to-severe aperiodicity. Recent evidence suggests that these endoscopic imaging techniques (with increased spatial resolution of up to 8,000 frames per second) have potential for objectively characterizing normal and disordered vibratory motion in adults and children. High-speed digital imaging and kymography have the potential to provide quantitative and visual-perceptual measurements of vibratory function that researchers can use to improve the assessment and treatment of voice disorders in children and adults.
