Summary
A total of 333 patients with a diagnosis of functional dysphonia were studied by both
laryngeal electromyography (EMG) and spectral analysis. EMG and acoustic analysis
revealed that some patients with so-called functional dysphonia diagnosed by physical
examination alone in fact suffered from a variable degree of laryngeal nerve paralysis.
Laryngeal EMG plays an important role in determining whether patients with a diagnosis
of functional dysphonia have organic disease of the laryngeal nerves.
