The aim of this study was to explore the value of transcutaneous laryngeal ultrasonography in the diagnosis of vocal fold polyps. From December 2016 to June 2019, 87 patients with vocal fold polyps diagnosed pathologically in the Otolaryngology Head and Neck Surgery Department of the Second Affiliated Hospital of Xi'an Jiaotong University were enrolled and examined by electronic laryngoscopy and percutaneous laryngeal ultrasound on the same day before operation. To observe the effect of calcification length as a percentage of thyroid cartilage at the glottic level on vocal fold display, the characteristics of ultrasound images of vocal fold polyps and the value of transcutaneous laryngeal ultrasonography in the diagnosis of vocal fold polyps were assessed. Among 87 patients, the calcification rate of thyroid cartilage at the glottic level was 33.3%. The differences in calcification rate and percentage of calcification length between males and females were statistically significant. The rate of detection of vocal folds decreased gradually with an increase in calcification length percentage. Imaging features of vocal fold polyps were hypo-echoic with a clear boundary and regular shape. The detection rates for circular and non-circular polyps were 92.0% and 70.6%. Ultrasound was more likely to detect circular than non-circular polyps; however, the difference was not significant. Transcutaneous laryngeal ultrasonography can identify the morphology and location of vocal fold polyps and is non-invasive and highly accurate. Therefore, it has the potential to be an effective supplement to laryngoscopy for initial screening and post-operative review of vocal fold polyps.
本研究旨在探讨经皮喉超声在诊断声带息肉中的价值。2016 年 12 月至 2019 年 6 月，西安交通大学第二附属医院耳鼻喉科头颈外科共收治 87 例经病理诊断为声带息肉的患者，所有患者均于术前同日接受电子喉镜和经皮喉超声检查。观察甲状软骨在声门水平的钙化长度占比对声带显示的影响，评估声带息肉超声图像特征及经皮喉超声诊断声带息肉的价值。87 例患者中，甲状软骨在声门水平的钙化率为 33.3%。男女患者甲状软骨钙化率和钙化长度百分比差异有统计学意义。随着钙化长度百分比的增加，声带的检出率逐渐降低。声带息肉的影像学特征为低回声，边界清晰，形态规则。圆形和非圆形息肉的检出率分别为 92.0%和 70.6%。超声更易检测出圆形息肉，而非圆形息肉；但差异无统计学意义。经皮喉超声可识别声带息肉的形态和位置，具有非侵入性和高度准确性。因此，它有可能成为声带息肉初始筛查和术后复查的喉镜的有效补充。
