Videostroboscopy is a medical procedure used to visualize the vocal folds in motion. This technique uses a stroboscope, which emits a series of high-speed flashes of light, to create a slow-motion effect of the vocal folds' movement. This allows for a detailed examination of the vocal folds' structure and function, aiding in the diagnosis of various voice disorders.
Procedure[edit]
The procedure of videostroboscopy involves the use of a flexible endoscope or a rigid laryngoscope. The choice of instrument depends on the patient's comfort and the specific information required. The endoscope or laryngoscope is inserted through the patient's nose or mouth, respectively, and positioned above the larynx to visualize the vocal folds. The stroboscope then emits flashes of light in synchronization with the patient's vocal fold vibrations, creating a slow-motion video of the vocal folds in action.
Applications[edit]
Videostroboscopy is primarily used to diagnose voice disorders, such as vocal fold nodules, vocal fold polyps, and vocal fold paralysis. It can also be used to monitor the progress of treatment for these conditions. In addition, videostroboscopy can provide valuable information for voice therapy, helping to guide therapeutic interventions and assess their effectiveness.
Advantages and Limitations[edit]
One of the main advantages of videostroboscopy is its ability to provide a detailed view of the vocal folds in motion, which cannot be achieved with standard laryngoscopy. This can aid in the diagnosis of subtle abnormalities that may not be visible on a static image.
However, videostroboscopy also has some limitations. The procedure requires patient cooperation and can be uncomfortable. It may not be suitable for patients with severe gag reflex or those who are unable to tolerate the endoscope or laryngoscope. Furthermore, the stroboscopic effect is based on the periodic vibration of the vocal folds, and may not accurately represent irregular or chaotic vocal fold vibrations.
