Predictive Value of Kushida Index and Acoustic Pharyngometry for the Evaluation of Upper Airway in Subjects With or Without Obstructive Sleep Apnea
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…
Increased Upper Airway Collapsibility in Children with Obstructive Sleep Apnea during Wakefulness
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…
Solid Modeling of Human Vocal Tract using Magnetic Resonance Imaging and Acoustic Pharyngometer
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…
Changes in the Human Vocal Tract Due to Aging and the Acoustic Correlates of Speech Production
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…
Utility of Noninvasive Pharyngometry in Epidemiologic Studies of childhood Sleep- disordered Breathing
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…
Acoustic Reflection: Review and Clinical Applications for sleep-Disordered Breathing
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…

Detection of Positional Airway Obstruction in Neonates by Acoustic Reflection
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…
Predictive Value of Pharyngometry Derived Measurements for Oral Appliance Treatment of Obstructive Sleep Apnea Syndrome
Chest, 2000
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.”
Comparison of Glottic Areas Measured by Acoustic Reflections vs. Computerized Tomography
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…
Objective evaluation of velopharyngeal function by acoustic reflection measurements
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,…
