Abstract
Laryngeal electromyography (LEMG) has been utilized for nearly 70 years in the evaluation of voice and swallowing disorders, but many controversies still exist regarding the utility and interpretation of the data it provides. Applications have been developed for using LEMG in the evaluation of vocal fold paralysis, dysphagia, laryngeal sensation, and even voice production research. LEMG data interpretation and standardization of results between different investigators are ongoing challenges. Current research is expanding the role for needle and surface LEMG techniques to study the larynx in states of health and disease. This review summarizes recent advances in LEMG and discusses the current controversies in the use of LEMG in modern otolaryngology.
