BEST ENT DOCTOR IN MUMBAI-INDIA, Stroboscopy With Microlaryngoscopy

Stroboscopy, Video Stroboscopy or Laryngeal Stroboscopy is a special method of examination of a vibrating or fast moving object, such as the vocal folds.
It uses a synchronized, flashing light passed through a flexible or rigid telescope. The flashes of light from the stroboscope are synchronized to the vocal fold vibration at a slightly slower speed, allowing the examiner to observe vocal fold vibration during sound production in what appears to be slow motion.
This slow motion picture is an illusion, as the speed of actual vocal fold vibration is not changed by stroboscopy. This special viewing allows the voice care team to evaluate each vocal fold's vibration properties during the different phases of the vocal fold's vibration cycle. Because vocal fold vibration is so fast, the slow motion view is actually derived from many successive vibration cycles. The information acquired from the stroboscopic examination of the vocal folds is essential for planning effective phonomicrosurgery (endoscopic surgery to enhance vocal function). Optimal human voice production is dependent on optimal vocal fold vibration. This requires aerodynamically competent closure of vocal folds along with pliable phonatory mucosa.
Videostroboscopy fulfills several important requirements of a complete office voice examination. It provides useful, real-time information concerning the nature of vibration, an image to detect vocal pathology, and a permanent video record of the examination
Laryngeal videostroboscopy continues to be the imaging modality of choice by voice clinicians due to its historical use and ability to efficiently capture many salient vocal fold vibratory characteristics. Because visual and objective assessments of certain laryngeal features can be unreliable using stroboscopic imaging, further research is warranted into the integration of laryngeal high-speed videoendoscopy and other alternate imaging modalities into routine clinical practice to improve the management of voice disorders.
