What is Laryngeal Videostroboscopy?

Laryngeal videostroboscopy is a state-of-the-art voice assessment in which an endoscope is paired with a strobe light in order to assess the structure and vibratory characteristics of the vocal folds. The vocal folds vibrate 120-210 a second depending on a patient's gender, so we are unable to see their movement with the naked eye. Videostroboscopy works by taking multiple pictures of the vocal folds in movement and editing them into a continuous video, so we can assess movement parameters and deficits.

According to the American Speech-Language-Hearing Association, it is best practice for speech-language pathologists working with patients who have voice disorders to either perform or refer to an instrumental examination completed in conjunction with a physician prior to initiating voice therapy. This is due to the inability to see how the voice is working along with any other co-occurring medical conditions through office-based assessment alone.

Through utilizing techniques such as laryngeal videostroboscopy, more accurate results are able to be collected, meaning a better understanding of vocal physiology and better patient outcomes!
