Abstract:
Objective:To study the effect of surrounding tissues on the minimum cross-section area(minCSA) of upper airway in non-snoring males.Methods: Upper airway scanning by magnetic resonance imaging(MRI) was conducted in 83 non-snoring males aged 22 to 57 years. The correlation between the minCSA of upper airway and the linear, area and volume measurement items about the morphology of the surrounding tissues was analyzed. Results: The minCSA was in velopharynx or glossopharynx. In non-snoring males,the main relative factors to minCSA were transverse dimension/ transverse distance between mandible(r=0.700), transverse dimension/ pharyngeal wall thickness(r=0.680), and parapharyngeal fat volume(r=-0.290). The velopharynx was more prone to be affected by the surrounding tissues than the glossopharynx. The location of the parapharyngeal fat, the lateral pharyngeal wall and parapharyngeal fat volume had the most obvious influence on the velopharyngeal size in sequence. While the thickness of the lateral pharyngeal wall was the main factor which influenced the size of glossopharynx. Conclusion: The feature of surrounding tissues has certain influence on minCSA of upper airway in non-snoring males.
