Videostroboscopy is a specialised examination of the vocal folds (vocal cords) using an endoscope placed through the nose or mouth to examine the larynx (voice box) with a strobe light. This special light source allows assessment of the vibration of the vocal folds. The examination is recorded for detailed review and for following progress.

David has a stroboscope in his consultation rooms and has extensive experience in the interpretation of this examination. David also performs videostroboscopy at the Voice Clinic at Auckland City Hospital and at North Shore Hospital.
