Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pharyngeal sensitivity is a determinant parameter of pharyngeal functioning, particularly regarding protective dilator reflexes of upper airway. Preliminary results have suggested that the use of this parameter in diagnosis algorithm such as linear discriminant analysis and random forest could predict the presence of sleep apnea syndrome in almost 98% of patients. Our study aims at validating a new diagnosis method of sleep disordered breathing which will be compared with nocturnal polysomnography, the reference method to diagnose sleep disordered breathing. Pharyngeal sensitivity will be measured using the SENSITEST device which allows an automatic measurement of the pharyngeal sensation. The use of this parameter in diagnosis algorithm will be compared with polysomnographic results.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sleep apnea subjects

Patients with suspected sleep apnea syndrome will have nocturnal polysomnography. According to the number of respiratory events per hour of sleep, patients will be classified as "sleep apnea" or "controls". All the patients will be blindly assessed for pharyngeal sensitivity the morning following the nocturnal recording.

* instable dentures
* exaggerated gag reflex preventing pharynx examination
* no visibility of the soft palate
* systemic or topical anti-inflammatory treatments
* treatments that may increase the occurence of nocturnal respiratory events and/or leading to daytime sleepiness and cognitive impairment
* cardiac failure, or symptoms suggesting cardiac failure
* history of stroke
* contraindication for using xylocaine spray
* no affiliation to national insurance
* patient participating in another research study involving drugs that may interfere with sleep recordings and/or measurement of pharyngeal sensation
