Stroboscopy

Stroboscopy is a specialized endoscopic technique used to evaluate vocal cord vibration during phonation. It employs a synchronized flashing light to create a slow-motion view of the mucosal wave, allowing detailed assessment of vocal fold function. It is indicated in patients with hoarseness, voice disorders, vocal cord lesions, and suspected early malignancy.

Performed in an outpatient setting using a rigid or flexible endoscope, it provides valuable information on symmetry, amplitude, and periodicity of vocal fold movement. The procedure is safe, well tolerated, and essential for precise diagnosis and voice assessment.
