Summary

Nasofibroscopy is the gold standard for laryngeal pathology diagnosis. However, this examination is invasive and can be poorly tolerated in the pediatric population. Laryngeal ultrasound appears to be a better tolerated alternative. However, few data exist in the pediatric population in the literature. The aim of this study is to evaluate the feasibility of laryngeal ultrasound in a larger pediatric population of pathological and non-pathological subjects.

Detailed description

According to current knowledge, the gold standard for diagnosing laryngeal pathologies is flexible fiberoptic laryngoscopy (FFL), as it allows visualisation of the motricity of the laryngeal structures and the appearance of the mucous membranes. However, this is an invasive examination, which can be poorly tolerated in the pediatric population. This poor tolerance can make it difficult to obtain an accurate diagnosis because of the child's movements. With the aim of improving patient comfort without compromising diagnostic performance, some studies describe laryngeal ultrasound (LUS) as an alternative to FFL. This imaging examination appears to be better tolerated than FFL because it is less invasive for the patient. However, there are few data available in the infant population. The main limitations of LUS are obtaining a satisfactory ultrasound window and inter-rater reproducibility. For these reasons, the aim of this study is to assess the feasibility of LUS in the pediatric population and to obtain reference frame enabling the different laryngeal structures to be visualised. We will include around one hundred patients treated in the pediatric ENT unit, with or without laryngeal pathology. An ultrasound record will be performed during the consultation in addition to the usual examination. The record will be analysed by a blinded assessor. A single consultation will be required and no follow-up is planned.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	laryngeal ultrasound	laryngeal ultrasound with linear probe will be positioned on the patient's neck. A list of anatomical sites to be visualised will be determined beforehand. Once all the pre-determined structures have been visualised, in an axial and sagittal plane, we will note the position of the ultrasound probe and its orientation. This will enable us to determine the ideal position of the ultrasound probe for obtaining all the elements of interest on a section that will be called the reference section.
