For the purpose of investigating the change of the laryngoscopic finding in case of the vocal cord paralysis, the authors made the precise examinations of 15 cases, operated for the struma carcinomatosa, with the complication of the postoperative unilateral permanent vocal cord paralysis. In this series, operative findings of the injury grade, especially on the recurrent and superior laryngeal nerve at ions of the paralysed vocal cords had been observed for 2 years after the operation, with recording the electromyograph of the intrinsic laryngeal muscles. The following conclusions were obtained. In the changes in positions of the paralysed vocal cords, two main currents were permitted : one, fixation in the median or paramedian position (40%), chiefly seen in the group without cutting of the recurrent laryngeal nerve and the other, transition from the median or paramedian position to the intermediate position (46.7%), chiefly seen in the group with cutting of that nerve. (2) Summarizing the changes in positions of the paralysed vocal cords with the lapse of time after the operation, the median or paramedian position was assumed at first, and later the intermediate position. With the electromyographic investigations, this finding can be explained by gradual progress of the lowering of the function of the cricothyroid muscle, caused by the degeneration of the superior laryngeal nerve fibers due to the operative influences. (3) From these investigations the complexity of the laryngeal function was again shown the necessity of the clarification of the conditions relating to the vocal cord paralysis was emphasized and new points for future studies were realized.
