[Pseudohypertrophy of the ventricular bands due to deformation of the thyroid cartilage].
Hoarseness due to phonation by the false cords (dysphonia plicae ventricularis) is a common cause of functional dysphonia, in relation to excessive muscular tension in the larynx area. Nevertheless, a mechanic cause can be observed in some cases with dysphonia plicae ventricularis, which is usually due to deformation of the thyroid cartilage. We report a case with hypertrophy of the ventricular bands which was treated by vocal rehabilitation followed by suspension laryngoscopy with partial removal of the ventricular bands, without further improvement. This failure was related to a pseudohypertrophy of the ventricular bands, due to deformation of the thyroid cartilage, which was confirmed by computed tomography.
