本文对１７例部分喉切除病人进行发音及呼吸功能检测，并以１２例正常人作为对照，结果是：垂直组与正常组基频无显著差别，但最低音的值比正常组高，最高音值比正常组低；频率微扰（ｊｉｔｔｅｒ）值比正常组高。舒适频率发音时，最长发音时间较正常组减少，气流率比正常组增加。其肺活量与预测值比较无显著差别，但呼气流速容量曲线的峰值及最大中间呼气流量与预测值比较明显减少，说明有不同程度的喉阻塞存在。水平组的呼吸功能正常，气流率、ｊｉｔｔｅｒ值接近正常值。
In this paper, 17 cases of partial laryngectomy patients with pronunciation and respiratory function tests, and 12 normal controls as a result, the vertical group and the normal group at the fundamental frequency was no significant difference, but the value of the lowest tone than the normal group, the highest tone Value is lower than normal group; jitter value is higher than normal group. When the comfortable frequency pronunciation, the longest pronunciation time reduced compared with the normal group, the airflow rate increased than the normal group. There was no significant difference between the vital capacity and the predicted value, but the peak value of the expiratory flow rate volume curve and the maximal middle expiratory flow rate decreased significantly compared with the predicted value, indicating that there were different degrees of laryngeal obstruction. The level of normal breathing function, airflow rate, jitter value close to normal.
