Abstract

We describe an unusual laryngeal anomaly incidentally detected in an adult male patient who had suffered from chronic dysphonia since infancy with no change of voice quality over time. Laryngostroboscopy revealed a formation originating below the anterior commissure and protruding through the vocal folds, which computed tomography scan showed to be a calcified spur on the internal surface of the thyroid cartilage. The patient's clinical history of long-term dysphonia with a stable voice quality suggests that the anomaly may be congenital. To the best of our knowledge, no similar laryngeal malformations have been previously described.
