Laryngostroboscope
A laryngostroboscope is to observe the movements of a vocal cord during phonation. Our hospital has a full HD laryngostroboscope. This magnifies the vocal cord by moving 100 to 300 times a second, and shows its movements in slow motion or stop motion that leads to an accurate diagnosis. Laryngostroboscopy is to check whether the vocal fold mucosa moves well, whether the vocal fold mucosa vibrates properly, whether the vocal cord moves regularly, whether the vocal fold mucosa moves symmetrically, whether the vocal cord contact is safe, and whether gastric acid runs back.
