Conclusion: “This study demonstrates that sitting awake patients with idiopathic OSA have significantly smaller cross sectional areas of the pharynx and the glottis than do subjects without OSA. This study also demonstrates and anatomic predisposition to the development of upper airway occlusion that may not be detectable on clinical examination, but that is detectable with acoustic reflections.”
