摘　　要：目的分析声带息肉声像图特点,初步探讨高频超声在声带息肉诊断中的应用价值。方法收集2016年12月至2021年9月在西安交通大学第二附属医院经术后病理诊断为声带息肉的患者169例,共176个息肉,总结声带息肉的超声图像特点,观察声门水平甲状软骨钙化特点以及声门水平甲状软骨钙化范围对声带息肉显示的影响。结果声带息肉声像图均表现为上皮层与韧带层之间出现局限性均匀低回声,形态可表现为类圆形与扁平形,并有高张力与低张力之分,彩色多普勒显示96.8%的息肉内未见血流信号。与扁平息肉相比,超声更易检出类圆形息肉,但二者之间差异无统计学意义(P>0.05);男性声门水平甲状软骨钙化发生率高于女性,差异有统计学意义(P<0.05);声门水平甲状软钙化范围影响声带息肉显示率,随着钙化范围增大,声带息肉显示率逐步降低,无钙化组与中度、重度钙化组之间声带息肉显示率差异有统计学意义(均P<0.05)。结论声带息肉有典型的声像图表现,高频超声可辨别声带息肉的形态、位置、大小,尤其对于声门水平甲状腺软骨无钙化及轻度钙化的患者,超声可达到准确诊断的目的,有望成为喉镜检查的有效补充,应用于声带息肉的初步筛查及术后复查。Objective To explore the characteristics of vocal cord polyps and to study the application value of high-frequency ultrasound in the diagnosis of vocal cord polyps.Methods A total of 169 patients diagnosed with vocal cord polyps(176 polyps in total)by pathology in the Second Affiliated Hospital of Xi′an Jiaotong University from December 2016 to September 2021 were collected,the ultrasonic image characteristics of vocal cord polyps were summarized,and the characteristics of thyroid cartilage calcification at glottic level and the influence of the calcification range of thyroid cartilage at glottic level on the display of vocal cord polyps were observed.Results The sonogram images of all vocal cord polyps showed the localized uniform low echo between the upper cortex and the ligament layer,the morphology could be circular and flat,and all polyps could be divided into high tension type and low tension type,no blood flow signal was found in 96.8%of the polyps.Round polyps were more easier to be detected by ultrasound than flat polyps,but there was no significant difference(P>0.05).The incidence of thyroid cartilage calcification at glottis level was higher in men than in women,and the difference was statistically significant(P<0.05).The range of thyroid cartilage calcification at the glottic level affects the display rate of vocal cord polyps.With the increase of calcification range,the display rate of vocal cord polyps gradually decreased.There was significant difference in the display rate of vocal cord polyps between non calcification group and moderate calcification group,non calcification group and severe calcification group(all P<0.05).Conclusions Vocal cord polyps have typical sonographic appearance.High-frequency ultrasound can identify the morphology,location and size of vocal cord polyps.Especially for patients with no or mild calcification of thyroid cartilage at glottic level,ultrasound can meet the requirements of accurate diagnosis.It is expected to become an effective supplement to laryngoscopy,and a
