ABNORMAL MOVEMENTS OF THE GLOTTIS

_Garcia_ states, in his observations, that sometimes when the

rims of the vocal ligaments have come together, there remains

between the arytenoid cartilages a triangular space, which

does not close until the tone is produced. _Czermak_ likewise

describes this process in his pathological investigations,

and also a similar one with the laryngoscope. While, namely,

the arytenoid cartilages seem to be wholly closed, one sees

just before the beginning of the tone the vocal ligaments

standing apart in a square-shaped form, and only closing

together with the tone. At first, before I had attained to

much practice in observation, I often saw these processes

in myself, and later often in others.

That these accidental forms of the glottis bear no relation to

the generation of sounds, as _Funke_ truly says, is made evident

by an irregularity in the combined action of the muscles of the

larynx, by which the coming together of the arytenoid cartilages

takes place later than that of the ligaments, or that of the

ligaments later than that of the arytenoid cartilages.

As recently great importance has often been ascribed to these

abnormal movements of the glottis in the generation of sound,

I have felt bound to mention them.
