Treatment of spasmodic dysphonia by means of resection of the recurrent laryngeal nerve. 1988

H Schiratzki, and B Fritzell
Department of Otorhinolaryngology, Karolinska Institutet, Huddinge Hospital, Sweden.

Over the last twelve years 44 patients suffering from spasmodic dysphonia have been seen at Huddinge hospital. There were 34 women and 10 men. 22 of these patients were for various reasons not regarded as candidates for surgery. The opposite applied to the remaining 22 patients. The outcome of a temporary nerve block guided us (the surgeons and the patients) whether to operate or not. 12 patients were thus operated upon by means of resection of the right recurrent laryngeal nerve. The immediate post-operative result was excellent in 11 of 12 patients but the voice deteriorated in 4 patients. They had revision surgery with a successful result in 3 of them. Also the other 7 patients deteriorated to some extent but not to the degree that revision surgery was necessary. It is our hypothesis that recurrencies are caused by reinnervation of the sectioned nerve.

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.

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.

D014832 Voice Disorders Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA.
