To compare high-speed videolaryngoscopy (HSV) parameters such as open quotient (OQ), amplitude symmetry index (ASI), phase symmetry index (PSI), and frequency symmetry index (FSI), of the unilateral vocal cord paralysis (UVCP) patients pre and post (after 6 months) autologous fat augmentation.
This retrospective study evaluated all age and gender patients with UVCP that underwent autologous fat augmentation from July 2016 to July 2019. The OQ, ASI, PSI, and FSI were calculated from the HSV recordings by using the montage and fast Fourier transform point analysis. The pre-and post-operative means were compared using a paired student t-test, with a p-value less than 0.05 considered significant.
A total of 37 patients, age 41.2 ± 11.3 years (21 to 67 years), 59.4% females and 40.6% males, were included in the study. The average duration of symptom onset was 2.3 ± 0.87 months. The post-operative mean values of OQ, ASI, PSI, and FSI following the fat augmentation were significantly improved compared to the pre-operative mean values with p-values <0.0001, 0.0018, 0.0011, and 0.0006, respectively.
There was a significant improvement in the OQ, ASI, PSI, and FSI in UVCP patients after 6 months of autologous fat augmentation, signifying an enhanced vibratory function. The ability of HSV to measure the minute details of vocal cord vibration by providing quantitative measurements has also been highlighted. The need for future prospective research with an increased sample size and longer duration of follow up is recommended.
比较单侧声带麻痹（UVCP）患者自体脂肪移植前后（6 个月后）高速视频喉镜（HSV）参数，如开口商（OQ）、幅度对称指数（ASI）、相位对称指数（PSI）和频率对称指数（FSI）。
本回顾性研究评估了 2016 年 7 月至 2019 年 7 月期间行自体脂肪移植的所有年龄和性别 UVCP 患者。通过蒙太奇和快速傅立叶变换点分析，从 HSV 记录中计算 OQ、ASI、PSI 和 FSI。使用配对学生 t 检验比较术前和术后的平均值，p 值小于 0.05 认为有统计学意义。
共纳入 37 例患者，年龄 41.2±11.3 岁（21-67 岁），女性 59.4%，男性 40.6%。症状发作的平均持续时间为 2.3±0.87 个月。与术前相比，自体脂肪移植后 OQ、ASI、PSI 和 FSI 的术后平均值均显著改善，p 值均<0.0001、0.0018、0.0011 和 0.0006。
UVCP 患者自体脂肪移植 6 个月后，OQ、ASI、PSI 和 FSI 显著改善，提示声带振动功能增强。HSV 通过提供定量测量来测量声带振动的细微细节的能力也得到了强调。建议进行未来前瞻性研究，增加样本量并延长随访时间。
