Abstract: Objective　To investigate the results of upper airway parameters and localization of upper airway obstruction in males with varying degrees of obstructive sleep apnea hypopnea syndrome（OSAHS） detected by fibre nasopharyngoscopy（FN） versus magnetic resonance imaging（MRI），and based on this，to analyze the correlation and consistency of the two methods for the localization of upper airway obstruction in these patients.Methods　We enrolled 93 OSAHS patients who received treatment in Department of Otolaryngology，Head and Neck Surgery，Jinhua Central Hospital from May 2014 to December 2015，including 32 with mild OSAHS（mild group），31 with moderate OSAHS（moderate group），and 30 with severe OSAHS（severe group）．The collapse degree of the hinder parts of the soft palate，the tongue and epiglottis was measured with FN.The cross-sectional area，left-right dimension and front-back dimension of the hinder part and thickness of pharyngeal wall of the soft palate，the tongue and the epiglottis were measured by MRI.SPSS 15.0 statistical software was applied to analyze the measurement results of the two methods.Results　The collapse degree，cross-sectional area，left-right dimension and front-back dimension of the hinder part of the soft palate，the tongue and epiglottis，and the lateral wall thickness of the epiglottis differed significantly between the three groups（P<0.05）．Pearson correlation analysis found that，the collapse degree and the cross-sectional area of hinder part of epiglottis were positively correlated in the mild group（r=0.53，P=0.002），while they were negatively correlated in the moderate group（r=-0.53，P=0.002）．The results of localization of upper airway obstruction by FN were consistency with MRI（Kappa=0.390，P=0.007）．Conclusion　Both FN and MRI can detect the airway soft tissue compliance and anatomical features in patients with varying degrees of OSAHS，but for the localization of upper airway obstruction，they have no correlation and consistency.Therefore，in order to comprehensively assess the upper airway obstruction in these patients，these two methods can be used together.
