All underwent full clinical evaluation, including physical examination, nasolarybgoscopy and polisonography. We classified individuals into groups by the value of the apnea-hypopnea index (AHI), calculated measures of association and analyzed differences by the Kruskal-Wallis and chi-square tests. Results Results ResultsResults Results: all patients with obesity type 2 had OSAS. We found a relationship between the uvula projection during nasoendoscopy and OSAS (OR: 4.9; p-value: 0.008; CI: 1.25-22.9). In addition, there was a major strength of association between the circular shape of the pharynx and the presence of moderate or severe OSAS (OR: 9.4, p-value: 0.002), although the CI was wide (1.80-53.13). The septal deviation and lower turbinate hypertrophy were the most frequent nasal alterations, however unrelated to gravity. Nasal obstruction was four times more common in patients without daytime sleepiness. The other craniofacial anatomical changes were not predictors for the occurrence of OSAS. Conclusion Conclusion Conclusion Conclusion Conclusion: oral, pharyngeal and laryngeal disorders participate in the pathophysiology of OSAS. The completion of the endoscopic examination is of great value to the evaluation of these patients. The pathophysiology of OSAS is multifactorial, however evidence shows that UA muscle control is the result of a delicate balance between different forces of intraluminal pressure during inspiration, which leads to a negative transpharyngeal pressure gradient, and the extraluminal pressure forces derived from muscle contractions that contribute to opening of the pharynx. Factors such as vasomotor tone and mucosal adhesive forces seem to collaborate with UA narrowing or collapse 3 . ...

Perfil miofuncional orofacial de pacientes com distúrbios do sono: relação com resultado da polissonografia

“…Changes in uvula structure corresponded to more severe results in polysomnographic examination. In addition, the presence of edema was significantly related to mild and / or moderate outcome (25) . It is known that upper airways soft tissue size -such as the uvula -is determined by genetic conditions but can be affected by environmental factors such as inflammation, infection and infiltration by metabolic components, alternating the tone and shape of the muscles of these structures, predisposing to narrowing and collapse during sleep (26) .…”

Does face mask affects sleep quality in patients with nasal septal deviation: evaluated by mini sleep questionnarie

“…However, it is known that these patients have lower sleep quality (17,18). In addition, since the need for sleep and daytime sleep is higher in this population, the transition to sleep is faster (19). Therefore, it was thought that they might need sleep medication less than the normal population.…”

Prevalence of predictive factors for obstructive sleep apnea in university students

“…This reinforces the importance of analyzing the factors together and in a context. Findings from Dias et al ( 2015) 16 and Araújo-Melo et al (2016) 17 showed that Mallampati classification is a predictive factor that presents considerable changes even in people without the disease.…”
