ENT · Larynx and airway: laryngeal electromyography

Sample item

A patient has a vocal fold paralysis for 2 months. Which test predicts recovery by showing polyphasic reinnervation potentials versus fibrillation potentials?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Laryngeal electromyography

Laryngeal EMG assesses motor unit potentials in the thyroarytenoid and cricothyroid. Fibrillation potentials without motor units suggest denervation with poor recovery, whereas polyphasic units suggest reinnervation. It guides timing of permanent medialisation.

Option by option

  • A. CT neck

    CT shows structural lesions.

  • B. Videostroboscopy

    Stroboscopy shows vibration, not nerve function.

  • C. Laryngeal electromyography (correct)

    Correct. EMG gives prognosis in paralysis.

  • D. Acoustic analysis

    Acoustic analysis quantifies voice quality.
