Recurrent laryngeal nerve section in the treatment of spastic dysphonia. 1981

J F White, and R E Knight

Spastic dysphonia is a severe vocal disability in which the patient speaks with hyperadducted vocal folds. The resulting abnormality is characterized by excessively low pitch, vocal tremor, laryngospasms, and strain-strangle voice quality. Until recently the disorder was regarded as psychogenic and treated unsuccessfully with speech therapy and psychotherapy. New evidence supports the theory that the etiology is neurologic, requiring management designed to alter neurophysiologic function. Section of the recurrent laryngeal nerve provides immediate results and a new voice virtually free of the previous unpleasant characteristics.

UI	MeSH Term	Description	Entries
D007823	Laryngeal Nerves	Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.

D007826	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.	Laryngospasm,Laryngeal Spasm,Laryngeal Spasms,Laryngospasms,Spasm, Laryngeal,Spasms, Laryngeal

D012009	Recurrent Laryngeal Nerve	Branches of the vagus (tenth cranial) nerve. The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. They carry efferents to all muscles of the larynx except the cricothyroid and carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D014832	Voice Disorders	Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.
