[Dysphonia in adults caused by unilateral pseudohypertrophy of the ventricular band with deformation of the thyroid cartilage. Apropos of three cases]

Abstract

The association of dysphonia appearing in adulthood with unilateral bulging of the false cord associated with a convex deformation of the overlying thyroid cartilage is to be remarked in three cases. The origin, which was presumably acquired by gradual deformation of the thyroid cartilage with age, is discussed in the light of the literature and the clinical history. A past traumatic cause can also be implicated (1 case). CT-Scan is essential for the diagnostic of the cartilage deformation and eliminates laryngeal tumors. In one of the cases reported, we were able to demonstrate the possibility of treatment by CO2 laser resection of the false cord hypertrophy.
