title: Calcified spur of the thyroid cartilage.
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.
