Troubles oro-myo-fonctionnels & Syndrome d' Apnées Obstructives du Sommeil (SAOS) : impact sur la voix et la cognition

Abstract : Objective : This study assesses the importance of orofacial myofunctional disorders in the context of Obstructive Sleep Apnea Syndrom (OSAS) and their impact on cognition and voice. The literature describes three major altered functions in the OSAS: orofacial functions, cognitive function, and vocal function.
Material and Method : The population is composed of 11 patients with a Body Mass Index (BMI) less than 35 kg / m2: 4 subjects «No OSAS», 2 subjects «Mild OSAS», 1 subject «Moderate OSAS» and 4 subjects «Severe OSAS». The orofacial assessment evaluates 5 major areas : Face, Eyes, Lips, Cheeks & Mandible and Tongue. Cognitive assessment consists of an evaluation of memory in everyday life. Finally, the acoustic analysis are performed from an / a/ held.
Results : The results show that subjects with high Apnea Hypopnea Index (AHI) have impaired lingual motor skills (p=0.03). The depressor labii inferioris is impaired too, and hinder the lower lip motricity. The impact of lingual dysfunction on cognitive function is significantly confirmed in prospective memory (p=0,0032) and temporospatial orientation (p=0,018), and the desaturation index is correlated to the Global Memory Index (GMI) of the Rivermead Behavioral Memory Test (RBMT). Finally, there is no correlation between the lingual deficit and the vocal parameters. Only genioglossal / diaphragm coupling seems to be dysfunctional, thus altering the Maximal Phonation Time (MPT) of men. The abnormalities of sleep affect the fundamental frequency, the Harmonics-to-Noise Ratio (HNR) and the MPT ofwomen.
