James, PA, MPH; Danna Lei, BS; Aliya Hashemi BS; Benjamin Reed Sponsor: American Academy of Otolaryngology-Head & Neck Surgery Objectives: 1. Develop a composite measure of the nasal airway including objective and subjective validated parameters.…
Sleep Apnea Research Group Principal Investigator: Edward M. Weaver, MD, MPH Co-Investigators: Judy Stenstrom LPN, BA This study confirms the inter-rater and test-retest reliabilities of minimum cross-sectional area measurements of the nasal airway using acoustic rhinometry. Methods – Two separate examiners measured minimum cross-sectional area with acoustic rhinometry on 25 normal volunteers on three consecutive…
Sleep Apnea Research Group Principal Investigator: Derek J. Lam, MD Co-Principal Investigator: Edward M. Weaver, MD, MPH Co-Investigators: Kathryn T. James, PA, MPH American Journal of Rhinology (in press) Background – Studies comparing different categories of nasal measures have reported inconsistent results. We sought to compare validated measures of the nasal airway: anatomic (acoustic rhinometry),…
Tufts University–Pediatric Dentistry Authors: Jorge Landa, Alfred Rich, and Matthew Finkelman Rationale: “Currently, dentists and orthodontists rely on subjective visual assessment of the airway extraorally, and by analyzing panoramic radiographs and noting apparent structural and anatomical abnormalities. Once again this current modality of analysis lacks a standardized norm and is subject to human error and…
Sleep Apnea Research Group Principal Investigators: N. Husen, MD; E.M. Weaver, MD Abstract: “Poor tolerance and inadequate use are the greatest limitations to CPAP therapy for sleep apnea. This retrospective cohort study evaluated 306 patients who were prescribed CPAP therapy for sleep apnea at the University of Washington’s Sleep Disorders Center during the period January…

Introduction:
Obstructive sleep apnea syndrome is defined as symptomatic repetitive obstruction of the upper airway during sleep (1) and occurs in 2
Sleep Breath, 2010 Authors: Okun, M.N., Hadjiangelis, N., Green, D., Hedli, L.C., Lee, K.C., Krieger, A.C. Summary: “In summary, this study revealed some interesting findings related to airway dynamics in children with obstructive sleep apnea as compared to snorers The airway measurements using AR in this sample demonstrated larger nasal airway volume and area during…
(Accepted for Publication, 11/23/2009) Authors: Jorge Landa, Alfred Rich, and Matthew Finkelman Conclusion: “A very strong correlation was found between the anterior nasal cross-sectional area calculated from the radiographs, and the anterior nasal cross-sectional area and nasal volume from the rhinometer. “The acoustic rhinometer can be a very instrumental and reliable adjunct during the course…
Otolaryngology and head and neck surgery, 2008 Authors: Morris, L., Burschtin, O., Setlur, J., Bommelje C., Lee, K.C., Jacobs, J. B., Lebowitz, R. A. Objective: Obstructive sleep apnea events are more common in REM sleep, although there is no relationship between sleep phase and pharyngeal airway status. We studied the patency of the nasal airway…
Brazilian Journal of Otorhinolaryngology, 2008 Authors: A. de Oliveira Camargo Gomes, A. C. Martins Sampaio-Teixeira, S. H. Kiemle Trinadade, I. E. Kiemle Trinadade Conclusion: “This study used acoustic rhinometry to determine the reference values for nasal cross-sectional areas to be used, for comparison purposes, in the analysis of adults with functional and/or anatomical nasal obstruction.…
The Proceedings of the American Thoracic Society , 2008 Authors: Terri E. Weaver and Ronald R. Grunstein Relevance: “There is emerging evidence that increased nasal resistance affects CPAP use and initial acceptance of this treatment. Using acoustic rhinometry to measure the internal dimensions of the airway, those patients with smaller nasal cross-sectional area and reduced…

Conclusion: “
Otolaryngology–Head and Neck Surgery, 2006 Authors: J. P. Corey Conclusion: “In Summary, we should use acoustic rhinometry because it can be a valuable aid in the diagnosis of nasal airway obstruction in both adults and children. New standards for its use have been recently published. Acoustic rhinometry can now be used to aid in the…
American journal of rhinology 2006;20(5):456-62. Authors, Lal Devyani; Gorges Melissa L; Ungkhara Girapong; Reidy Patrick M; Corey Jacquelynne P Abstract: BACKGROUND: Acoustic rhinometry has been used to assess nasal patency and to calculate nasal cavity volume. This study used acoustic rhinometry to assess changes in nasal patency after alterations in posture, unilateral mechanical obstruction, temperature,…
American Journal of Rhinology, Volume 20, Number 2, March-April 2006 , pp. 133-137(5) Authors: Morris, Luc G.; Setlur, Jennifer; Burschtin, Omar E.; Steward, David L.; Jacobs, Joseph B.; Lee, Kelvin C. Abstract: Background: Nasal continuous positive airway pressure (nCPAP) is usually the first-line intervention for obstructive sleep apnea, but up to 50% of patients are…
