Abstract

Diseases of the larynx and trachea are a group that includes various diseases. Their diagnosis often requires invasive methods. Ultrasound is a non-invasive, reproducible and safe diagnostic method, and thanks to recent technological developments, even small structures can be imaged very precisely and evaluated by dynamic examination. It will be possible. From 2022 to 2023, 300 randomly selected stable newborns born between 32 and 42 weeks of gestation will undergo ultrasound scans of the larynx and trachea. The results of this study are presented after collecting data according to the adopted methodology. This is the first study to date to describe the ultrasonic anatomy of the larynx and trachea and to establish a reference range for the size of individual laryngeal and tracheal structures in the neonatal population. We believe that our work will contribute to the further development of this part of sonography and, in the future, reduce the number of invasive procedures in the diagnosis of these organs.
