Smaller Nasal Volumes as Stigmata of Aberrant Neurodevelopment in Schizophrenia

American Journal of Psychiatry, 2004 Authors: Moberg, P.J, Roalf, D.R, Gur, R.E., Turetsky, B.I. Method: ” A measurement of nasal volume was acquired by acoustic rhinometry for 40 male schizophrenia patients and 24 healthy male comparison subjects.” Results: “The patients had smaller posterior nasal volume than the comparison subjects but did not differ in anterior…

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…

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…

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…

Assessing Orthotic Normalization of Pharyngeal Dynamics

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…
