[The implication of the cricothyroid muscle in paralysis of the vocal cords (author's transl)]. 1975

I Lakatos, and H von Stuckrad

A report is given about one patient with bilateral paralysis of the vocal cords. After local anesthesia of the piriform sinus and novocain blockade of the R. externus of the superior laryngeal nerve of the same side a widening of the glottis and an improvement of the respiration was observed. After section of the R. externus of the superior laryngeal nerve we could observe even an improvement of the same effect as it has been observed after local anaesthesia. These observations were proved by spirography and photo-documentation. Because of paradox movements of the vocal cords a narrowing of the glottis was observed during inspiration. Therefore the patients dyspnea did not improve to the extent as it could be expected from the widening of the glottis after this therapy. The problems are discussed in relation to the literature.

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.

D014826	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.
