Diagnosis of benign laryngeal tumors is based on direct or indirect visualization of the larynx, supplemented by CT.

Removal restores the voice, the functional integrity of the laryngeal sphincter, and the airway. Smaller lesions may be excised endoscopically by using a CO2 laser and general anesthesia. Larger lesions extending beyond the laryngeal framework often require pharyngotomy or laryngofissure.
