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: Should We Be Using It?

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…

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,…

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…

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…

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…

Acoustic Rhinometry in the Evaluation of Nasal Obstruction

Laryngoscope, 1995 Authors: R. Roithmann, P. Cole, J. Chapnik, I. Shpirer, V. Hoffstein, N. Zamel Conclusion: “From a clinical point of view, the area-distance function curve [acoustic rhinometry] helps the clinician to differentiate objectively and quantify the mucosal and the structural component of nasal obstruction and to assess results of medical and/or surgical treatment. AR…

The Objective Assessment of Nasal Patency

Ear, Nose, and Throat Journal, 1993 Authors: V. W. S. Lai, MD and J. P. Corey, MD, FACS Conclusion: “Acoustic Rhinometry may become a helpful diagnostic tool as use of the technique grows. It may help the clinician in making an anatomical diagnosis to pinpoint the location and etiologic factors causing nasal obstruction. It also…

Septoplasty and Compensatory Inferior Turbinate Hypertrophy: A Randomized Study Evaluated by Acoustic Rhinometry

The Journal of Laryngology and Otology, 1993 Authors: L.F. Grymer, P. Illum, O. Hilberg Conclusion: “Septoplasty increased the areas of the narrow side significantly in both groups. The increase in area in group B was surprisingly little. This is probably an expression of the limitation of septoplasty in the treatment of slight septal deviations. The…
