Ultrasonography is an accessible diagnostic tool that allows noninvasive examination of the larynx and trachea, thereby minimally disturbing patient comfort. Despite the interest of ultrasonographers in these organs, specific normative values for the dimensions of their structures have not been published. This prospective cohort study aimed to establish the normal sizes for the laryngeal and tracheal structures, as assessed using ultrasound, within a neonatal population.
Between 2022 and 2023, experienced sonographers conducted ultrasonographic examinations of the larynx and trachea on 300 healthy newborns of Caucasian descent born between 32 and 42 weeks of gestation. Dimensions of the larynx, thyroid cartilage, vocal folds, glottis, epiglottis, subglottic region, trachea, epiglottis, and infrahyoid muscles were measured.
Normative values were determined for the specific structures of the larynx, trachea, and infrahyoid muscles. The normative sizes for the evaluated structures were determined separately for each sex because of the significant differences observed between the groups.
The results of this study contribute to the advancement of knowledge regarding the structure and function of these organs and may play a crucial role in enhancing the quality of airway management for newborns. The published article serves as a summary of the data obtained from a study registered at ClinicalTrials.gov (identifier NCT05636410).
Question There are no standards for the size of specific parts of the larynx and trachea in the neonatal population on ultrasound examination. Findings The article discusses the ultrasonographic norms for the dimensions of individual laryngeal and tracheal structures, developed based on the studies of 298 neonates. Clinical relevance Knowledge of ultrasound reference values for the size of laryngeal and tracheal structures facilitates the diagnosis of diseases of these organs and allows individualizing the approach to newborns, especially those requiring intensive care.
超声检查是一种可及的诊断工具，能够对喉和气管进行无创检查，从而将对患者舒适度的干扰降至最低。尽管超声检查人员对这些器官感兴趣，但尚未公布其结构尺寸的具体规范值。这项前瞻性队列研究旨在确定新生儿群体中通过超声评估的喉和气管结构的正常尺寸。
在2022年至2023年期间，经验丰富的超声检查人员对300名妊娠32至42周出生的白种裔健康新生儿进行了喉和气管的超声检查。测量了喉、甲状软骨、声带、声门、会厌、声门下区域、气管、会厌和舌骨下肌群的尺寸。
确定了喉、气管和舌骨下肌群特定结构的规范值。由于各组之间观察到显著差异，因此分别为每种性别确定了评估结构的规范尺寸。
本研究结果有助于推进对这些器官结构和功能的认识，并可能在提高新生儿气道管理质量方面发挥关键作用。发表的文章是对从ClinicalTrials.gov注册的一项研究（标识符NCT05636410）中获得的数据的总结。
问题 超声检查中新生儿群体喉和气管特定部位的大小没有标准。研究结果 本文讨论了基于对298名新生儿的研究得出的喉和气管各结构尺寸的超声规范。临床意义 了解喉和气管结构大小的超声参考值有助于诊断这些器官疾病，并有助于针对新生儿，尤其是需要重症监护的新生儿采取个体化治疗方法。
