截面积

Methods: One hundred patients with OSAHS were enrolled in this study and divided into two groups: the stricture group (24 cases) and the nonstricture group (76 cases). The dimension of the lingual region airway, the thickness of the retropharyngeal and the lateral pharyngeal tissue, and the width and length of the tongue were determined.

Results: There was no difference of age, BMI, AHI and pulse oxygen between the stricture group and the nonstricture group. The coronal and the arrow diameters of the stricture group were less than those of the nonstricture group. The thickness of the retropharyngeal and lateral pharyngeal wall, and the width and length of the tongue of the stricture group were larger than those of the nonstricture group.
