🎥 Stroboscopy

Seeing the Voice in Motion

The human voice is produced through rapid vibration of the vocal folds, occurring hundreds of times per second—far too fast for the naked eye to observe.
Stroboscopy is an advanced diagnostic technique that uses flashes of light synchronized with vocal vibration to create the illusion of slow-motion movement. This allows physicians to study how the vocal folds open, close, and vibrate in extraordinary detail.

At Yoskarn Clinic, this technology forms the cornerstone of accurate voice assessment and personalized treatment planning.

How Stroboscopy Works

During a stroboscopic examination:

1. A small flexible or rigid scope equipped with a strobe light and camera is positioned to view the larynx.

2. As the patient phonates (produces sound), the strobe light flashes slightly out of sync with the vibration frequency.

3. This creates a series of images that appear as continuous slow-motion footage, revealing even subtle irregularities in vibration.

Stroboscopy helps specialists identify issues such as:

• Incomplete vocal fold closure

• Nodules, cysts, or polyps

• Asymmetrical vibration

• Scar tissue or stiffness

• Early signs of functional or structural voice disorders

The Value of Stroboscopy in Voice Care

Unlike standard laryngoscopy, stroboscopy shows how the vocal folds move—not just what they look like.
This dynamic information is vital for diagnosing professional voice users, singers, teachers, and anyone experiencing hoarseness or vocal fatigue.
