Journal of Clinical Sleep Medicine, 2005 Authors: K. Monahan, H. L. Kirchner, S. Redline Conclusion: “We concluded that (1) acoustic pharyngometry identifies differences in upper airway characteristics based on gender, ethnicity, and SDB status and (2) novel parameters can assist in quantifying these pharyngeal phenotypes. The novel parameters can potentially facilitate quantitative, as an adjunct…
Journal of Korean Medical Science, 2004 Authors: D. G. Jung, H. Y. Cho, R. R. Grunstein, B. Yee Conclusion: “The morphometric measurement of oral cavity and acoustic pharyngometry enables an examiner to predict the presence or absence of OSA rapidly and accurately during an initial visit. Through this study we found the sensitivity and specificity…
Journal of Craniomandibular Practice, 2004 Author: J. S. Viviano, B.Sc., D.D.S. 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…
American Journal of Respiratory and Critical care Medicine, 2004 Authors: D. Gozal and M. M. Burnside Conclusion: “This study shows that acoustic pharyngometric measurements of the upper airway before and after topical anesthesia provide a reproducible measure of Upper Airway Collapsibility in awake children. Furthermore, a cutoff value derived from the differences in cross-section area…
Proceedings of the 26th Annual International conference of the IEEE EMBS , 2004 Authors: H. Z. Tameem and B. V. Mehta Conclusion: “The geometric information such as cross-sectional area and the volume of the vocal tract can be obtained using the [Eccovision] Acoustic Pharyngometer. The accuracy of this device is verified during this research and…
Journal of Speech, Language, and Hearing Research, 2003 Authors: S. A. Xue and G. J. Hao Conclusion: “This investigation used a derivation of acoustic reflection (AR) technology to make cross-sectional measurements of changes due to aging in the oral and pharyngeal lumina of male and female speakers. The purpose of the study was to establish…
Sleep and Breathing, 2002 Authors: J. S. Viviano, D.D.S. Conclusion: “The potential clinical usefulness of AR in the treatment of patients with SDB involves all stages of treatment: initial screening of patients, establishing patient candidacy, evaluating nasal patency, determining mandibular posture that optimizes airway patency, determining orthotic titration settings, and verifying continued efficacy of orthotic…
American Journal of Respiratory and Critical Care Medicine, 2002 Authors: K. J. Monahan, E. K. Larkin, C. L. Rosen, G. Graham, and S. Redline Conclusion: “The usefulness of any diagnostic test depends on numerous factors, including its feasibility, predictive ability (regarding predicting clinical endpoints or discriminating subgroups of the population), precision (or reliability), accuracy, and…
American Jornal of Respiratory and Critical Care Medicine, 2000 Authors: P. Jarreau, B. Louis, L. Desfrere, P. W. Blanchard, D. Isabey, A. Harf, and G. Moriette Conclusion: “In conclusion, this study showed that the [Acoustic Reflection] method is an effective way to diagnose abutment of an ETT against the tracheal wall in infants. The method…

Authors: D. I. Loube, MD, N. J. Ball, D. Phil, D. F. Schmidt, P. J. Nehring
Conclusion: “Airway volume determined by acoustic Pharyngometry may be a useful measure to predict OA treatment response and could minimize the need for post-treatment polysomnography.”
