Cheeks Appearance as a Novel Predictor of Obstructive Sleep Apnea The CASA Score Study

Summary

Cheeks appearance is a screening tool developed based on cheeks observation to identify volume, flaccidity or both to predict people with probable obstructive sleep apnea.

Conditions

• Obstructive Sleep Apnea
• Breathing, Sleep-Disordered
• Muscle Weakness
• Muscle Disorder
• Face
• Swallowing Disorder

Interventions

DIAGNOSTIC_TEST

CASA score protocol to Non-obstructive sleep apnea Group

CASA score observe the cheeks appearance: volume of the cheeks (0, 1, 2 or 3) and flaccidity, (0, 1, 2 or 3). The final score is volume + flaccidity score to have the CASA score (0-6). A photography was captured to enable the blinded evaluation of three evaluators of each participant. Ultrasonography was positioned in the face of the participant and slide to capture the muscle image (masseter muscle, buccinator and the tongue). Tongue and cheeks pressure were assessed with a device with a small bulb. Inside the mouth in the tongue, the participant is instructed to press the bulb against the hard palate. In the cheeks, the bulb is placed between the cheek and the teeth and the participant press the bulb with the cheek. Swallowing evaluation with an endoscope that enters in the nose of the participant to observe the the oropharynx; while the participant is eating liquid consistency, pureed consistency and solid food.

CASA score protocol to Severe obstructive sleep apnea Group
