Diseases of vocal cords and larynx, not elsewhere classified (J38)
Clinical Information
Laryngismus - A disorder in which the adductor muscles of the VOCAL CORDS exhibit increased activity leading to laryngeal spasm. Laryngismus causes closure of the VOCAL FOLDS and airflow obstruction during inspiration.
Laryngomalacia - A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the LARYNX. This results in a floppy laryngeal wall making patency difficult to maintain.
Vocal Cord Paralysis - Congenital or acquired paralysis of one or both VOCAL CORDS. This condition is caused by defects in the CENTRAL NERVOUS SYSTEM, the VAGUS NERVE and branches of LARYNGEAL NERVES. Common symptoms are VOICE DISORDERS including HOARSENESS or APHONIA.
