This study aimed to analyse vocal performance and to investigate the nature of the neoglottal sound source in patients who had undergone supracricoid laryngectomy with cricohyoidoepiglottopexy, using a highspeed digital imaging system.The waveform of the estimated volume flow at the neoglottis, obtained by inverse filtering analysis, corresponded well to the neoglottal vibration patterns derived by multiline kymography. These findings indicated that the specific sites identified at the neoglottis by the present method were likely to be the sound source in each patient. High-speed digital imaging analysis is effective in locating the sites responsible for voice production in patients who have undergone supracricoid laryngectomy with cricohyoidoepiglottopexy. This is the first study to clearly identify the neoglottal sound source in such patients, using a high-speed digital imaging system.

本研究的目的是分析发声性能和调查的性质，在接受了环状软骨上喉切除术与环舌骨会厌固定术患者的新声门声源，使用高速数字成像系统的波形估计的体积流量在新声门，通过逆滤波分析，得到的，以及对应的新声门振动模式的多线kymography。这些结果表明，在新声门的本方法确定的特定网站可能是声源在每个病人。高速数字成像分析是有效的定位网站负责谁接受了环状软骨上喉切除术与环舌骨会厌固定术的患者的声音产生。这是第一项使用高速数字成像系统明确识别此类患者的新声门声源的研究。
