 Laryngeal EMG


At the Voice Assessment Centre we work closely with the Department of Neurophysiology at St Vincent’s Hospital which specialises in neurolaryngology. To provide more information about the functioning of the nerves and muscles of the vocal folds, you may be referred for Laryngeal Electromyography (LEMG). LEMG is a procedure where the neurologist inserts a small needle (like an acupuncture needle) into the muscle that controls movement of the vocal fold to measure its neural activity. LEMG is important in determining the prognosis for neural recovery. A vocal fold paralysis may take up to a year after injury to recover. LEMG can help determine if the damaged vocal fold is likely to regain function. This will help in planning the type and extent of any surgical intervention or treatment.
