Stroboscopy is a specialized endoscopic imaging technique used to visualize the vocal folds (vocal cords) in slow motion. Because the vocal folds vibrate at 100–400 times per second (too fast for the naked eye), a stroboscope uses a flashing light synchronized with the vibration frequency. This creates a series of apparent still images, allowing doctors to see the mucosal wave —the ripple of tissue across the vocal fold surface. Stroboscopy has a wide range of applications in

Stroboscopy is a Greek word that means "twisted" or "turning." In the context of physics, stroboscopy refers to the use of brief, intense light flashes to illuminate an object in motion. By synchronizing the light flashes with the object's motion, the object appears to be stationary or moving in slow motion. This creates a series of apparent still images,

| Parameter | Normal finding | Abnormal finding | |-----------|----------------|------------------| | Symmetry | Folds meet symmetrically | One fold lags (paralysis) | | Periodicity | Regular vibrations | Irregular (spasmodic dysphonia) | | Amplitude | Moderate opening | Reduced (scarring) or excessive (flaccid fold) | | Mucosal wave | Ripples smoothly over fold edge | Absent (cancer) or stiff (scar) | | Glottic closure | Complete closure | Gap (paralysis, atrophy, paresis) |
