| 摘要: |
| 目的：评价高频超声显示正常成人声带区结构的能力。方法：对104名健康成人志愿者进行声带区超声成像。以甲状软骨为声窗,采取前侧横切面,从前至后显示声带区结构,并实时观察声带区结构的运动情况。总结声带区解剖结构声像图特点,并且分析超声成像水平在男女性别中的差异及其年龄差异。结果：声带区结构超声显示能力的差异表现为显示深度的不同,各解剖结构的显示率分别为：甲状软骨100%、假声带、真声带和杓状软骨93.97%、声门裂84.62%、杓肌、后侧环状软骨板和环杓后肌73.08%。超声显示水平男女间有显著差异(P ＜ 0.01),且不同显示水平年龄有显著差异(P ＜ 0.01)。结论：超声对正常成人声带区解剖结构具有较好的显示能力,可满足超声评价声带麻痹研究的需要。 |

| Abstract: |
| Objective: to value the imaging ability of high frequency ultrasonography for anatomic structure of vocal cord area. Methods: Ultrasonography was performed in 104 healthy volunteers. The anterior cross sections of vocal cord area were observed from front to back, taking thyroid cartilage as the acoustic window, and their real-time movements were also observed. The ultrasonographic features were summarized and the distribution of ultrasonic imaging levels in gender and its difference in age were analyzed, respectively. Results: The imaging ability of ultrasonography for vocal cord was manifested as the imaging depth. Detection rates of vocal cord structures were 100% in thyroid cartilage, 93.97% in false vocal cord, true vocal cord and arytenoid cartilage, 84.62% for rima glottidis and 73.08% for arytenoid muscle, posterior lamina of cricoid cartilage, respectively. There were significant differences of ultrasonic imaging levels in gender and of ages between different levels (P ＜ 0.01 in both). Conclusion: There was a good imaging ability of ultrasonogrphy for anatomic structures of vocal cord area in normal healthy adults, which can meet the need of study on ultrasonography’s evaluating vocal cord paralysis. |
