[Vocal cord paralysis in the intermediary and paramedian position. Etiology and treatment].

The purpose of this paper is to recall the neuroanatomical bases of the motrice laryngeal innervation and the consequences of a lesion at that level. On the other hand, the type of management and effective therapy our service uses in those cases of unilateral of bilateral vocal cord paralysis. The management is principally based on the E.M.G., the objective phonatory measurements including the spectral voice analysis. The unilateral paralysis is usually treated by the speech pathologist reeducation and, if necessary, GAX collagen injection in the vocal cord. The bilateral paralysis, generally in adduction, is cured in the most cases with a CO2 laser arytenoidectomy.
