Abstract |
Vocal cord paralysis is a comlex disorder which may result from numerous causes. It is often associated with trauma, disease in adjacent tissue, or a generalized neuroligical disorder.
Laryngeal EMG is a useful technique for vocal cord paralysis. However it has not been
used due to the uncertainties of normal human vocal cord physiology and the technical
difficulties in performing these studies.
We investigated the pathophysiology of vocal cord paralysis with laryngeal
electromyography(LEMG). We studied 20 patients with idiopathic vocal cord paralysis. 6
patients were denervated in the cricothyroid(CT) and 6 patients in the
thyroarytenoid(TA), and 3 patients in both CT and TA muscles.
These indicated superior laryngeal neuropathy, recurrent laryngeal neuropathy, and
proximal laryngeal or vagus neuropathy, respectively. LEMG proved to be a safe and
effective procedure in the diagnosis of laryngeal neuropathy, and make it possible to use
electromyography as a routine procedure in diagnosis laryngeal paralysis. |
