Videostroboscopy is a specialized endoscopic procedure that allows for the examination of the vocal folds during phonation, typically by illuminating them with a strobe light to capture their motion. This technique provides critical insights into both the vibratory characteristics of the vocal folds and any potential pathologies present.
The primary function of videostroboscopy is to observe the vibratory motion of the vocal folds in detail, making it possible to assess their movement patterns, symmetry, and coordination during speech. This is particularly valuable in identifying issues such as nodules, polyps, or other lesions that may affect voice production. Additionally, the technology can reveal subtle abnormalities in the timing and regularity of vocal fold vibration that might not be noticeable during a standard examination.
This capability is crucial for speech-language pathologists and otolaryngologists as it helps inform diagnosis and treatment planning for individuals experiencing voice disorders. By providing a dynamic view of vocal fold function, videostroboscopy stands out as a significant tool in the analysis of vocal fold health and activity.
