声门面积波形(GAW)是一个典型的声门周期中相对声门面积随时间变化的曲线图。它是通过对视频频闪图像的定量分析得出的。对24例喉显微手术患者手术前后进行了GAW分析。患者包括声带息肉、息肉样变性、囊肿、声沟和Reinke‘s水肿。测量并比较5个参数：声门最大标准化面积、最大开口率、最大闭合率、声门开放50%时的开放时间百分比和声门间隙大小。术后状态的统计学显著差异包括最大声门面积增加、最大开口率增加和最大闭合率增加。声门开闭率是衡量声带柔韧性的客观指标，具有临床意义。GAW可用于声带振动能力的量化。
Glottal area waveform (GAW) is the plot of relative glottal area versus time through 1 representative glottal cycle. It is derived from the quantitative analysis of the videostroboscopic image. A GAW analysis was performed on 24 patients before and after microlaryngeal phonosurgery. Patients with vocal fold polyps, polypoid degeneration, cysts, sulcus vocalis, and Reinke's edema were included. From each GAW, 5 parameters were determined and compared: maximum normalized glottal area, maximum opening rate, maximum closing rate, percent open time at 50% glottal opening, and glottal gap size. Statistically significant differences in postoperative states included an increased maximum glottal area, an increased maximum opening rate, and an increased maximum closing rate. Glottal opening and closing rate are objective measures of vocal fold pliability that have clinical relevance. The GAW may be used to quantitate vocal fold vibratory capability.
