Structural Vocal Pathologies Practice Test

Which sign is associated with laryngeal cleft?

Inspiratory/Expiratory Stridor Hoarseness Cough with hemoptysis Fever

Correct Answer:

Inspiratory/Expiratory Stridor

Explanation:

Laryngeal cleft is a congenital abnormal connection between the larynx and the esophagus, caused by incomplete separation of the airway and alimentary tract during development. This abnormal channel disrupts normal airway protection and often leads to airflow turbulence at the laryngeal level, producing audible noise known as stridor. Because the airway abnormality affects the larynx itself, the noise can be heard during both inspiration and expiration, making inspiratory/expiratory stridor a characteristic sign. Hoarseness typically signals vocal-tract or nerve issues rather than a direct laryngeal-esophageal defect. Cough with blood or fever points more toward infection or other pathology, not specifically laryngeal cleft.
