Recurrent laryngeal nerve injury following thyroid operations. 1977

G R Holt, and G T McMurray, and D J Joseph

Preoperative and postoperative laryngoscopy should be performed with thyroid operations. A prospective study of 121 thyroid operations from June 1970 to December 1974 was analyzed. There was a 4.2 per cent recurrent laryngeal nerve injury incidence in 217 nerves at risk, four of nine injuries being permanent. Of 217 superior laryngeal nerves at risk, 1.4% were injured, one of three permanently. Previous thyroid operations may place the laryngeal nerves at a greater risk. Transient edema of the laryngeal nerve in 13.4% of the patients was believed due to endotracheal intubation. There seemed to be no difference in the incidence of injury whether the nerves were seen or palpated. It is recommended that indirect laryngoscopy be performed in the course of evaluating thyroid disorders.

UI	MeSH Term	Description	Entries
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.

D013961	Thyroid Gland	A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.

D014827	Vocal Cords	A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.
