Confirming Nasal Airway Patency Observed on Panoramic and Posterior-Anterior Cephalometric Radiographs Using an Acoustic Rhinometer and ImageJ

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…

Abnormalities on Nasal Exam Associated with Decreased CPAP Tolerance and Use

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…

Acoustic rhinometry predicts tolerance of nasal continuous positive airway pressure: A pilot study

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…

Physiological change in nasal patency in response to changes in posture, temperature, and humidity measured by acoustic rhinometry.

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,…

Comparison between Acoustic rhinometry, Nasal Inspiratory Peak Flow, and Table of Scores in Patients with Rhinitis

International Archives of Otorhinolaryngology, 2005 Authors: Orcesi da Costa, G. G., Ctenas, B. B., Takahashi, D. Y., Mion, O. Mello, Jr., J. F., Butugan, O. Conclusion: 1). Acoustic Rhinometry (ARNM) presented statistically expressive correlation with signs and symptoms before and after vasoconstrictor use when analyzed five centimeters nostrils inward. 2). There was no statistically expressive…

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…

An Interpretation Method for Objective Assessment of Nasal Congestion with Acoustic Rhinometry

Laryngoscope, 2002 Authors: B. Mamikoglu, S. M. Houser, and J. P. Corey Conclusion: “Separate computed tomography (CT) and magnetic resonance imaging (MRI) correlation studies have confirmed the reliability of AR measurements.” “Objective nasal assessment with AR allows us to assess whether an obstruction is structural, mucosal, or mixed with an objective grading of the disease…

Effect of Nasal Surgery on the Nasal Cavity as Determined by Acoustic Rhinometry

Otolaryngology–Head and Neck Surgery, 1999 Authors: B. Kemker, X. Liu, A. Gungor, R. Moinuddin, and J.P. Corey Conclusion: “Acoustic Rhinometry (AR) was used to objectively measure the success of septoplasty in relieving nasal obstruction caused by septal deviation.” “AR measurements were successful in detecting increases in CSAs 1, 2, and 3 [Cross Sectional Areas] but…

The Role of Acoustic Rhinometry in Nasal Provocation Testing

Ear, Nose and Throat Journal, 1997 Authors: R. Roithmann, MD, I. Shpirer, MD, P. Cole, MD, J. Chapnik, MD, J. P. Szalai, PhD, N. Zamel, MD Conclusion: “We conclude that acoustic rhinometry is an alternative objective method for measuring nasal mucosa responses to allergen challenge and is as sensitive as nasal airflow resistance measurements. The…

Evaluation of the Nasal Cavity by Acoustic Rhinometry in Normal and Allergic Subjects

Otolaryngology–Head and Neck Surgery, 1997 Authors: J. P. Corey, MD, B. J. Kemker, MD, R. Nelson, and A. Gungor, MD Conclusion: “Acoustic rhinometry gives a valid two-dimensional impression of the anatomy of the nasal cavity, which illustrates areas of potential obstruction, congestion, or septal abnormalities. The technique has been demonstrated to be sensitive enough to…

Preoperative and Postoperative Nasal Septal Surgery Assessment with Acoustic Rhinometry

Otolaryngology–Head and Neck Surgery, 1997 Authors: L. Shemen and R. Hamburg Conclusion: “AR is useful in the objective diagnosis of nasal obstruction, namely, it can assist in differentiating reversible mucosal disease from medically irreversible structural abnormalities.” “AR can aid in the selection of appropriate management of nasal obstruction.” “AR is useful in the objective evaluation…
