Vocal cord paralysis

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Vocal cord paralysis is a relatively common clinical phenomenon, and is usually due to damage to the nerve supply.

All laryngeal muscles are supplied by the recurrent laryngeal nerves, the exception being the cricothyroids which are supplied by external branches of the superior laryngeal nerves.

This condition characteristically produces a 'bovine' cough.
