Abstract:
[ABSTRACT]OBJECTIVETo investigate the relationships between the characteristics of the upper airway anatomy, including the basis nasi, and the severity of obstructive sleep apnea hypopnea syndrome(OSAHS). METHODSFifty OSAHS patients and 40 normal subjects received three-dimensional CT scan and poly somnography(PSG). Variables between the two groups were compared. The association between the PSG parameters and the upper airway anatomic features were analyzed. RESULTSThere were significant differences in several CT variables between OSAHS patients and normal subjects(P<0.05), including the minimal lateral airway dimension and the minimal cross-sectional airway area of both velopharynx and glossopharynx, the minimal anterior-posterior airway dimension of velopharynx, and the airway width of basis nasi. The result of logistic regression analysis suggested that the minimal cross-sectional airway area of velopharynx and the airway width of basis nasi were significant predictors of the OSAHS(P<0.05, the values of the odds ratio were 0.978 and 0.589). The correlation analysis suggested that the airway width and the airway area of basis nasi both correlated significantly with several CT variables of pharynx(P<0.05), among these results, the correlation coefficents between these two variables and the mCSA of velopharynx were 0.536 and 0.425 respectively. CONCLUSIONNarrowed basis nasi and velopharynx might be important anatomical features in OSAHS patients. There are correlations between the characteristics of basis nasi and the anatomy of pharyngeal airway.
