Abstract

|
|
Diagnostic laryngeal electromyography (LEMG) relatively evaluates the electrophysiologic status of the larynx and provides critical clinical informations that no other tests can provide. However, LEMG is still not widely applied as a routine tool in clinical practice. One reason for this is the technical and interpretative difficulties of LEMG. But if LEMG is performed by a team approach consisting of an otolaryngologist and a neurologist, the technique and the interpretation of LEMG are not difficult to master. Another reason is that there is still not exact standard guideline for clinical application of LEMG. LEMG is an essential diagnostic test in evaluating patients with neuromuscular disorders, particulary vocal fold immobility, reduced mobility of vocal fold. The more we have used LEMG, the more we have found it useful in the evaluation and treatment of voice disorders, and the role of LEMG will be extended.
