Which type of endoscopic technique may include video stroboscopy?

The laryngeal mirror technique is a traditional method used for examining the larynx directly, but it does not typically involve any advanced imaging technologies. In contrast, video stroboscopy is a sophisticated technique that uses strobe lights to capture the rapid movement of the vocal folds during phonation, allowing for detailed analysis of voice production. This technique is particularly beneficial because it provides a visual assessment of the dynamics of vocal fold vibration at different pitch levels.

While other methods like cinematography, electromyography, and electroglottography provide valuable information about vocal function and muscle activity, they do not encompass the specific visual analysis features associated with video stroboscopy. Cinematography focuses on capturing motion but is not specifically utilized for laryngeal examination like stroboscopy. Electromyography measures electrical activity in muscles, which is important for understanding muscle function but does not provide images of the vocal folds. Electroglottography measures vocal fold contact area, which assists in assessing vocal function without the detailed visualization offered by stroboscopy. Therefore, laryngeal mirror technique, though basic, is the most relevant choice related to the inclusion of video stroboscopy in the context of examining the vocal folds.
