View Full Article (PDF) Abstract: Background: There is lack of reliable and accurate methods to predict treatment out- comes of oral appliance (OA) treatment. Acoustic pharyngometry (AP) is a non-inva- sive technique to evaluate the volume and minimal cross-sectional area of the upper airway, which may prove useful to locate the optimal position of OAs.…

DetailsInternational Journal of Pediatric Otorhinolaryngology Authors: S. A. Xue, L. Kaine, M I. Ng Abstract: AR technology has been extensively used as an objective diagnostic tool for locating structural and functional abnormalities within the oral and pharyngeal cavities, and in a variety of clinical applications, including (1) locating site and severity of vocal tract obstructions…
DetailsPresented at Respiratory Drug Delivery 2010, Orlando, Florida April, 2010 Authors: Kurt Nikander, Ian Petherbridge, Eugene Scargerry, dirk Von Hollen, John Viviano, Henry Chrystyn Summary: “Maximal lung deposition of inhaled aerosols is important in the treatment of respiratory diseases. The upper airways are known to affect the deposition of aerosol in the lungs. The design…
DetailsProsserman Centre for Health Research (Samuel Lunenfeld Research Institute), Mount Sinai Hospital, 2009 Author: Oded Friedman Discussion: Lower Body Positive Pressure Experiment “Upper airway cross-sectional area was determined using acoustic pharyngometry (Eccovision Acoustic pharyngometry; Sleep Group Solutions, Miami, Fl) at end-expiration. Two parameters, oropharyngeal junction area and mean cross-sectional area from the velum to the…
DetailsSleep Breath, 2009 Authors: L. Corda, S. Redolfi, L. Taranto Montemurro, G E. La Piana, E. Bertella, C. Tantucci Intro: “More easily and rapidly than MRI, acoustic pharyngometry can be used to assess the UA caliber and its change in OSAH patients.” Methods: “Acoustic pharyngometry UA anatomy was evaluated in the supine position by means…
DetailsEuropean Respiratory Journal, 2008 Authors: S. R. Patel, MD, J. M. Frame, E. K. Larkin, PhD, Susan Redline, MD, MPH Conclusion: “Our results suggest that upper airway dimensions derived via acoustic pharyngometry demonstrate substantial intra-familial correlation.” “Acoustic pharyngometry, because of its ease of use, is ideally suited for the study of the thousands of subjects…
DetailsAsian Biomedicine, 2007 Author: Robert L. Horchover Discussion: “Oral devices are not for every patient. An adequate evaluation should include a full medical examination and polysomnography to document sleep apnea severity and screening for predisposing factors associated with neck and shoulder muscles, including mandibular range of motion, occlusion, dentition and the intra-oral anatomy, tongue size…
DetailsRevista Brasileira de Otorrinolaringologia, 2007 Authors: M. Gelardi, A. Maselli del Giudice, F. Cariti, m. Cassano, A. Castelante Farras, J. L. Fiorella, P. Cassano Conclusion: “In our experience, acoustic pharyngometry allowed the precise observation of oral, pharyngeal and laryngeal cross-sections in the groups we studied by defining a characteristic and easily recognized airway network geometry.”…

Bradley Conclusion: “In healthy subject, displacement of fluid from the legs by LBPP causes distension of the neck and narrowing of the UA lumen. Fluid displacement from the lower to the…
DetailsClinical Linguistics and Phonetics, 2006 Authors: S. A. Xue, G. J. Hao, and R. Mayo Conclusion: “Research examining physiologic and acoustic characteristics of culturally diverse populations is sorely needed, but rarely reported. The major aim of this study was to quantify vocal tract dimensional parameters (oral length, oral volume, pharyngeal length, pharyngeal volume, total vocal…
DetailsJournal of Voice, 2006 Authors: S. A. Xue and J. G. Hao Conclusion: “Acoustic pharyngometry evaluates the geometry of the vocal tract with acoustic reflections and provides information about vocal tract cross-sectional area and volume from lip to the glottis. Variations in vocal tract diameters are needed for speech scientists to validate various acoustic models…
