Comparison of the upper airway morphology between Dutch and Chinese adults with obstructive sleep apnea

Abstract Purpose The pathogenesis of obstructive sleep apnea (OSA) is complex and may vary between different races. It has been suggested that the anatomical balance between skeletal tissues and soft tissues around the upper airway is a key pathophysiologic factor of OSA. Therefore, the aim of this study was to compare the anatomical balance of the upper airway between Dutch and Chinese patients with OSA based on cone beam computed tomography (CBCT) images. Methods This was a cross-sectional study performed in two centers and included Dutch and Chinese adults with OSA. CBCT scans in the supine... Mehr ...
