Conclusion: “Both non-invasive and accurate, acoustic reflectometry (AR) provides and objective measurement of the oral cavity and pharyngeal airway caudal to the velopharynx down to the glottis. Other advantages include ease of use and repeatability, inexpensive to perform, and high patient acceptance.”
“Although video endoscopy, CT, and MRI have all been used to assess the effect of mandibular advancement on the airway, the
low cost, ease of use and repeatability, and high patient acceptance of AR make it an ideal imaging modality for the purpose. The ability to take measurements in three dimensions and at 0.2 sec intervals allows the real time assessment of both structural and functional dynamics and facilitates evaluation of an orthotic’s ability to normalize the airway dynamics of a pathological airway.”
