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…
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…
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 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…
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…
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…

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.”
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…
Journal of Applied Physiology, 1998 Authors: A. D. D’Urzo, I. Rubinstein, V. G. Lawson, K. P. Vassal, A. S. Rebuck, A. S Slutsky, and V. Hoffstein Conclusion: “The acoustic reflection method is essentially a physiological tool, dedicated to performing only a single measurement, namely that of airway area. The major advantage of the acoustic reflections…
Mund Kiefer GesichtsChirurgie, 1998 Authors: M. Kunkel, U. Wahlmann, W. Wagner Introduction: “Today, acoustic rhinometry can be viewed as an accepted diagnostic tool, frequently used in the planning and follow-up of functional nasal surgery, as well as in the quantitative evaluation of allergic mucosal reactions. “Even for further peripheral airways, Jackson et al. reported that,…
Respiration, 1998 Authors: J. Huang, H. Shen, M. Takahashi, T. Fukunaga, h. Toga, K. Takahashi, N. Ohya Conclusion: “In conclusion, we measured pharyngeal parameters in a large number of normal subjects using the acoustic reflection technique with air breathing. The pharyngeal compliance was greater in the men than in the women, and it increased with…
Cleft Palate-Craniofacial journal, January 1998 Authors: M. Kunkel, U. Wahlmann, W. Wagner Conclusion: “Cleft palate and control patients showed overlapping ranges of velopharyngeal mobility, indicating that muscle function cannot be classified as normal or pathologic by a single acoustic measurement. An objective method of assessing velopharyngeal mobility may, however, provide a diagnostic tool for monitoring…
