Six of the eighteen cases were temporary; three of the six were caused by operative procedures in the clinic, and in the remaining fifteen the patients had developed the paralysis elsewhere before admission to the clinic.
FUNCTION OF THE CRICO-ARYTENOIDEUS POSTICUS MUSCLES
In bilateral abductor paralysis there is a loss of function of each crico-arytenoideus posticus muscle, which in normal function abducts the vocal cords, opening the glottis, and permits the free passage of air from the upper to the lower respiratory passages.
Cause of Loss of the Abductor Function.—To paralyze the crico-arytenoideus posticus muscles on both sides there must be one or more lesions either in the brain near the nuclei of the vagus or along the course of the
