从1983年到1993年，共有240例单侧声带麻痹（UVFP）患者在库鲁姆大学医院接受了经皮襞内硅胶注射（TCIFSI）以进行声带康复。评估其发声功能，并探讨TCIFSI对发声功能的影响。UVFP患者发声时气流增加；最大发声时间、发声基频（FO）范围和声压级（SPL）范围减小；语音信号中的基音扰动商、幅值扰动商和归一化噪声能量均有所增加。TCIFSI减少了气流，增加了发声时间和发声的FO和SPL范围，减少了声音信号中的基音和振幅扰动和噪声。患者自身主观评价显示TCIFSI术后声音有所改善。
A total of 240 patients with unilateral vocal fold paralysis (UVFP) underwent transcutaneous intrafold silicone injection (TCIFSI) for the purpose of vocal rehabilitation during the period from 1983 to 1993 in the Kurume University Hospital. Their vocal function was evaluated and the effects of TCIFSI upon the vocal function were investigated. The patients with UVFP presented with an increase in airflow during phonation; a decrease in maximum phonation time and fundamental frequency (FO) range and sound pressure level (SPL) range of phonation; and an increase in pitch perturbation quotient, amplitude perturbation quotient and normalized noise energy in the voice signal. TCIFSI resulted in a decrease in airflow, an increase in phonation time and FO and SPL range of phonation, and a decrease in pitch and amplitude perturbation and noise in the voice signal. Patient's own subjective evaluation presented with an improvement of his/her voice after TCIFSI.
