Abstract：
OBJECTIVE: Ultrasonography is a new method for subjective and qualitative assessment of true vocal fold movement, and true vocal fold visualization with the lateral approach could be better than that with the anterior approach. Our aim was to explore the feasibility of lateral-approach ultrasonography in objective and quantitative assessment of true vocal fold movement.
METHODS: The lateral-approach laryngeal ultrasonography was performed during calm breathing and breath-holding on young healthy adult volunteers in Shanghai, China. The morphology and anatomical position of false vocal fold, true vocal fold, and arytenoid cartilage were observed and measured through the ultrasonic self-contained measurement function. All parameters, including the distance from false vocal fold to thyroid cartilage lamina, true vocal fold length, and the distance from true vocal fold to thyroid cartilage lamina, were obtained at the end of the calm inspiratory and breath-holding phases. Data were analyzed using a t test (P < 0.05).
RESULTS: Forty healthy adult volunteers (age 20 to 34 years, body mass index 19.5 to 23.8 kg/m2, 20 males and 20 females) with satisfactory ultrasonic images were included in the study. There were no significant differences in all laryngeal parameters between the left and right sides in either phase (P > 0.05). From the end of the calm inspiratory phase to the breath-holding phase, changes in all laryngeal parameters were significantly different (P < 0.05), regardless of gender.
CONCLUSIONS: This study demonstrated that the lateral-approach laryngeal ultrasonography seemed feasible to quantify and objectively assess true vocal fold movement, utilizing differences between laryngeal parameters before and after true vocal fold movement.

摘要：
目的：超声检查是主观和定性评估真实声带运动的新方法，外侧入路的真实声带可视化可能比前路更好。我们的目的是探讨横向超声检查在客观和定量评估真实声带运动中的可行性。
方法：对上海年轻健康成人志愿者在平静呼吸和屏气期间进行侧入路喉部超声检查，中国。假声带的形态和解剖位置，真正的声带，通过超声自包含的测量功能观察和测量软骨。所有参数,包括从假声带到甲状软骨层的距离，真实声带折叠长度，从真正的声带到甲状软骨层的距离，在平静吸气和屏气阶段结束时获得。数据分析采用t检验(P<0.05)。
结果：40名健康成人志愿者（年龄20至34岁，体重指数19.5至23.8kg/m2，20名男性和20名女性）具有令人满意的超声图像。左右两侧喉部各项参数在任一阶段均无显著性差异(P>0.05)。从平静吸气阶段结束到屏气阶段,所有喉部参数变化均有显著差异(P<0.05),不分性别。
结论：这项研究表明，侧入路喉超声检查似乎可以量化和客观评估真实的声带运动，利用真实声带运动前后喉部参数的差异。
