Protocol for Tongue Elastography and Ultrasound Markers

NCT07024069 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 55

No results posted yet for this study

Summary

The purpose of this observational is to methodologically assess the standardisation and reliability of a protocol of ultrasound lingual markers, including tongue shear-wave elastography, attenuation indexes, and echo intensity in adult healthy subjects.

The main goals are to create a standardized protocol and its intra- et inter-rater reliability, in order to gather some data in a non-pathological population. This protocol will be used in further studies in the context of tongue fat accumulation, such as in obstructive sleep apnea syndrome.

Participants will be lying in supine position and after basic descriptive data collection (height, weight, neck circumference), submental ultrasound will be performed on them. This procedure is non-invasive, painless, safe (ultrasound does not involve ionising radiation) for the healthy participants.

Tongue ultrasound via submental approach

Descriptive and anthropometric data will be recorded for each participant, including age, sex, weight (kg), height (m), neck circumferences (cm). Body mass index (expressed in kg/m2) will be calculated. Submental ultrasound (US) images of the tongue will be performed on a patient lying supine, using a 5-15 MHz convex transducer. The parameters will be identical for all subjects and set at a depth of 9 cm, a focus of 4 cm and a gain of 45%. Each measurement will be taken thrice by a trained operator; the mean and standard deviation being used for analysis.
