Abstract:
Videostroboscopy is a valuable diagnostic tool in laryngology and voice disorders, offering additional information about vocal fold vibration that standard examination cannot detect. However, videostroboscopic data reported in current literature varies widely between authors. This study summarizes the applications of stroboscopy in recent research, and identifies reported stroboscopic parameters. Given the apparent lack of consensus, we consider the indications for and meaningful interpretation of videostroboscopy. Methods Review of 133 articles obtained from a Pubmed search with keywords “stroboscopy” and “voice” and limited to the English language and human subjects. Results Stroboscopy was reported in diverse clinical situations including paralysis, sulcus, benign glottic lesions, dysphonia, and in normal subjects. Most studies did not use a validated stroboscopy evaluation scale, instead choosing unique evaluation points. The numerous descriptive terms could be grouped into a few general parameters. The only parameter addressed in all articles was vocal fold closure, but with various differing criteria rating the quality or configuration of closure. Other common parameters included the mucosal wave, supraglottic effort, and vibration. However, mucosal wave symmetry and regularity of vibration were not universally addressed. Voice outcomes, if measured, were commonly reported without correlation to stroboscopic findings. Conclusion Recent literature presents diverse approaches to videostroboscopy. Some studies conducted a thorough examination of stroboscopic parameters, but others neglected key points. Stroboscopy was performed in several reports of glottic mass lesions or unilateral paralysis, even though vibratory dysfunction may be dwarfed relative to those greater derangements in causing dysphonia. Significance We submit a set of parameters for thorough videostroboscopy evaluation. We stress that videostroboscopy must be considered in the context of the voice and standard laryngeal exam.
