Dos
- Do have this test if a voice change persists beyond a few weeks without an obvious cause
Video Stroboscopy
A specialised slow-motion camera examination of the vocal cords, essential for diagnosing subtle voice disorders.
What is the condition?
Video stroboscopy uses a pulsing light synchronised to the vibration of the vocal cords to create a slow-motion view of how they move during speech. This reveals detail invisible to the naked eye or standard endoscopy — such as subtle stiffness, scarring, or asymmetry between the two cords — making it central to diagnosing conditions like nodules, cysts and scarring.
Treatment
What can be done?
A cornerstone diagnostic tool for any persistent voice change.
- Slow-motion assessment of vocal cord vibration
- Detects subtle scarring, stiffness or asymmetry
- Results discussed and often shown to the patient immediately
