本文介绍42例经皮折叠内硅胶注射技术及44例手术的功能效果。在局部麻醉下，病人仰卧位注射。针穿过环甲间隙插入。针的位置和注射效果是通过连接到电视摄像机和屏幕的纤维镜来监测的。使用由最大发声时间（MPT）、平均气流速率（MFRc）、发声基频（FO）范围和声压级（SPL）范围、音高扰动商（PPQ）、幅度扰动商（APQ）和归一化噪声能量（NNEa）组成的测试电池，对术前和术后的发声功能进行多维度评估。多数患者术后MPT、FO范围、SPL范围增加，MFRc、PPQ、APQ、NNEa降低。在基于这些参数的测试值的整体评价中，16个程序的结果为优，16个程序为好，7个程序为一般，5个程序为差。最常见的失败原因是注射量不足。
This paper presents the technique of transcutaneous intrafold silicone injection and the functional results of 44 procedures in 42 patients. The injection is given under local anesthesia with the patient in a supine position. The needle is inserted through the cricothyroid space. The location of the needle as well as the effect of injection is monitored by means of a fiberscope connected to a television camera and screen. The preoperative and postoperative vocal function was multidimensionally evaluated with the use of a test battery consisting of the maximum phonation time (MPT), mean airflow rate (MFRc), fundamental frequency (FO) range and sound pressure level (SPL) range of phonation, pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and normalized noise energy (NNEa). In the majority of the patients, MPT, FO range, and SPL range increased and MFRc, PPQ, APQ, and NNEa decreased postoperatively. In the overall evaluation based on the test values of these parameters, the result was excellent for 16 procedures, good for 16, fair for 7, and poor for 5. The most frequent cause of failure was an insufficient amount injected.
