Conclusion: “Previous studies employing the acoustic reflection technique, X- ray cephalometry, fluoroscopy, and computerized tomography have shown reduced upper airway caliber in patients with OSA. Our results confirm these findings by demonstrating that patients with OSA tend to have a lower pharyngeal cross section that the nonapneic control subjects.”
