Hysterical aphasia, also known as functional aphasia, is a hysterical manifestation of temporary impairment of laryngeal vocal function without organic changes. It is usually seen in female patients. The patient loses normal vocal function immediately after mental stimulation. Indirect laryngoscopy Indirect laryngoscopy shows that the shape and color of the vocal folds are not abnormal, the vocal folds can be abducted during inspiration, and the vocal chambers can be opened, but the vocal folds cannot be brought together in the midline when the “coat” sound is made. When the patient is asked to cough or laugh, the vocal cords can be seen to converge toward the midline, which can be distinguished from true adductor palsy. Before the diagnostic examination, the patient should have a detailed history of mental stimulation and a history of hysteria. Detailed observation of all parts of the larynx, especially the presence of small polyps of the vocal cords, subglottic tumors or lesions of the cricoarytenoid joint, is necessary during the examination. Those with suspicious organic lesions should be closely observed until they are not completely excluded, and the diagnosis of hysterical aphasia should not be made easily.
