IN HIS ARTICLE, Woo states that LEMG requires complilcated equipment, but he does not really delineate the different modes of using EMG. Morphologic assessment (detecting polyphasic potentials, fibrillation potentials, etc) addresses the status of innervation and does not really require any sophisticated equipment or computerized analysis, but it does require considerable training and experience. Kinesiologic assessment is much more complicated and does require computerized storage and analysis. Single-fiber EMG (not often used in the larynx) requires more sophisticated equipment.

The "Immobile Vocal Fold Evaluation" section states that "Office-based endoscopy may not differentiate among posterior glottic stenosis, cricoarytenoid ankylosis, . . . but it can differentiate between vocal cord paralysis and fixation." If this is true, then EMG would not be needed.

The clinical applications of LEMG are still evolving. Nevertheless, it is clear that LEMG is an indispensable tool in the clinical practice of neurolaryngology. It is not a standardized . . . [Full Text of this Article]
