A word of caution is here called for in the way of exami-nation. If the head of the patient be turned to one side, it iseasy to mistake a right-sided paralysis for one existing on theleft, and vice versd^ as the twisting of the head may give theimpression that the paralyzed band is the one which is in theposition for phonation. If, however, thebands be watched while the head is upright,it is easy to determine which is the activeone. Again, the mirror should be held in aposition to receive the image of the larynxin a vertical manner; a disregard of thisprecaution may give rise to the same error.
