Laryngeal Electromyography Techniques and Clinical Use.

Area of Science:

• Neurology
• Otolaryngology
• Speech-Language Pathology

Background:

• Laryngeal electromyography (LEMG) is a key diagnostic method for voice disorders.
• The technique has evolved significantly over decades due to increased interest from laryngologists and speech pathologists.
• Fewer neurophysiologists are involved in LEMG, potentially due to learning curve complexities and the need for a multidisciplinary approach.

Purpose of the Study:

• To review the essential anatomy and physiology for performing LEMG.
• To highlight the clinical utility of LEMG in the emerging field of neurolaryngology.

Main Methods:

• Literature review focusing on anatomical and physiological aspects of LEMG.
• Analysis of clinical applications and advancements in neurolaryngology.

Main Results:

• LEMG requires a solid understanding of laryngeal anatomy and neuromuscular function.
• The review provides foundational knowledge for practitioners.
• LEMG is crucial for diagnosing and managing various voice and laryngeal conditions within neurolaryngology.

Conclusions:

• LEMG is an indispensable tool for voice disorder diagnosis.
• Addressing the learning curve and fostering multidisciplinary collaboration can increase neurophysiologist participation.
• This review serves as a guide to understanding LEMG's role in neurolaryngology.
