  Purpose

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.

Primary Outcome Measures:
  • We aim to compare the novel diagnosis method with nocturnal polysomnography which is the reference method to diagnose sleep disordered breathing. [ Time Frame: Measurement performed the morning following the nocturnal polysomnography ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • We will determine the severity of sleep apnea for which pharyngeal sensitivity is predictive of sleep apnea syndrome. To simplify the procedure, we will precise the role of pharyngeal anesthesia in the diagnostic predictive value of the algorithm. [ Time Frame: similar to primary outcome measure ] [ Designated as safety issue: No ]

Arms Assigned Interventions
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.
Device: Measurement of pharyngeal sensitivity (SENSITEST)
Measurement of pharyngeal sensitivity using the SENSITEST the morning following the nocturnal polysomnographic recording to diagnose sleep disordered breathing.
