Role of Extracellular Fluid Volume in Inducing or Aggravating Obstructive Sleep Apnea-Hypopnea in Patients with Resistant Hypertension

Prosserman 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…

Short- and Long-term effects of CPAP on upper airway anatomy and collapsibility in OSAH

Sleep 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…

Heritability of Upper Airway Dimensions Derived Using Acoustic Pharyngometry

European 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…

Oral appliances for the treatment of obstructive sleep apnea

Asian 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…

Acoustic Pharyngometry: Clinical and Instrumental Correlations in Sleep Disorders

Revista 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.”…

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…

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…

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…
