Some are mild, and some are severe and need surgery. Although it has been suggested that the consequences of craniofacial craniofacial abnormalities and are more severe in Japanese than in Caucasian OSA patients [3], craniofacial abnormalities were not significantly related to AHI in both moderate-to-severe and non-to-mild OSA groups in the present study after adjustment for other risk factors, although further study is needed.

There was no overlap in those factors that were significantly associated with AHI, indicating a different pathogenesis of the disease between moderate-to-severe versus non-to-mild Abmormalities. The use of certain medicines during pregnancy has been linked with certain anomalies. Additional three-dimensional, volumetric evaluations using computed tomography [43] or magnetic resonance imaging [44] might show more sensitively the impact of anatomical imbalance on the pathogenesis of OSA. OSA is the result of structural and functional abnormalities that promote the repetitive collapse of the upper airway during sleep.

Additionally, in nonobese subjects, age alone had a significant relationship with the AHI. Genetic counselor. Craniofacial abnormalities and obesity it has been suggested that the consequences of craniofacial abnormalities are more severe in Japanese than in Caucasian OSA patients [3], craniofacial abnormalities were not significantly related to AHI in both moderate-to-severe and non-to-mild OSA groups in the present study after adjustment for other risk factors, although further study is needed. As we did for the overall group of patients, we performed stepwise multiple regression analyses to account for AHI in the moderate-to-severe and the non-to-mild groups, using the preselected variables that were significantly related to AHI.

However, the ratio of obesity to craniofacial bony size abnodmalities anatomical balance, an important determinant of upper airway volume and OSA risk was similar between Caucasians and Chinese OSA patients.

Anatomy of pharynx in patients with obstructive sleep apnea and normal subjects. In nonobese subjects, the falls in lung volume in a supine position are likely to lead to increased airway resistance, while in obese subjects in a supine position, such falls are smaller than in nonobese subjects and can only partly explain an increase in airway resistance [34].

Effects of uvulopalatopharyngoplasty on collapsibility of the retropalatal airway in patients with obstructive sleep apnea. Moreover, that age independently correlated with non-to-mild OSA but not moderate-to-severe OSA may partly support the evidence that with increasing age OSA prevalence increases but that its severity does not [19,29]. Mandibular position SNB angle was the single most important cephalometric variable that was strongly associated in determining the severity of OSA.

Analysis of variance was done craniofacial abnormalities and obesity evaluate the difference between the mean values of the cephalometric measurements in different AHI, BMI, and NC subgroups. Stepwise multiple regression analysis was performed to examine the relationships with AHI using the preselected variables that were significantly related to AHI in the above analyses Table 3.
