Conclusion: “The real-time display of airway areas is able to show the complex interdependencies of movement of the mouth, tongue, soft palate, naso-pharynx and glottis. These aspects have not been accessible to previous researchers, who did not process data in real time. Differences in upper airway caliber between subjects are important in the pathogenesis of the sleep apnea/hypopnea syndrome (Rodenstein et al 1990). Our study shows that our simplified acoustic reflection technique is a valid was of assessing upper airway caliber.”
