[Endo-ecto-laryngeal dysproportion: a frequent cause of dysplastic dysphonia (author's transl)].
A post-mutational laryngeal dysplasia is described which results in rapid vocal fatigue and chronic dysphonia. Pathognostically important in the respiratory position is a profile-deficient endolarynx, combined with hypoplastic Morgagni ventricle and distinct vocal cord contour in the phonatory position. We interpret this dysplasia as the consequence of a dysproportionate growth process during which the growth of the endolaryngeal soft tissue fails to match that of the laryngeal frame.
