Objective, Noninvasive Evaluation of Velopharyngeal Function in Cleft and Noncleft patients

Cleft Palate-Craniofacial journal, January 1998 Authors: M. Kunkel, U. Wahlmann, W. Wagner Conclusion: “Cleft palate and control patients showed overlapping ranges of velopharyngeal mobility, indicating that muscle function cannot be classified as normal or pathologic by a single acoustic measurement. An objective method of assessing velopharyngeal mobility may, however, provide a diagnostic tool for monitoring…

Objective evaluation of velopharyngeal function by acoustic reflection measurements

Mund Kiefer GesichtsChirurgie, 1998 Authors: M. Kunkel, U. Wahlmann, W. Wagner Introduction: “Today, acoustic rhinometry can be viewed as an accepted diagnostic tool, frequently used in the planning and follow-up of functional nasal surgery, as well as in the quantitative evaluation of allergic mucosal reactions. “Even for further peripheral airways, Jackson et al. reported that,…

Comparison of Glottic Areas Measured by Acoustic Reflections vs. Computerized Tomography

Journal of Applied Physiology, 1998 Authors: A. D. D’Urzo, I. Rubinstein, V. G. Lawson, K. P. Vassal, A. S. Rebuck, A. S Slutsky, and V. Hoffstein Conclusion: “The acoustic reflection method is essentially a physiological tool, dedicated to performing only a single measurement, namely that of airway area. The major advantage of the acoustic reflections…

Nasal Airway dimensions in Term Neonates Measured by Continuous Wide-band Noise Acoustic Rhinometry

Acta Otolaryngolica, 1997 Authors: P. G. Djupesland and B. Lyholm Conclusion: “The results presented in this study, confirming those from previous studies (11, 13), further emphasize the potentials and advantages of the acoustic reflection technique as an investigative tool in studies of respiratory dynamics in infants. The examination takes only seconds to perform, is non-invasive,…

Airway Dimensions in the Human Determined by Non-invasive Acoustic Imaging

Study Draft to Bruno Louis at INSERM U.292, 1997 Authors: B. Louis, P. Drinker, G. M. Glass, D. Isabey and J. J. Fredberg Conclusion: “The acoustic reflection method is a powerful tool to study the physiopathological properties of the upper airways. It permits, at the bedside and in the clinical situation, an accurate non-invasive and…

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…

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…

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…

The Nasal Valve and Current Technology

American Journal of Rhinology, 1996 Authors: P. Cole and R. Roithmann Conclusion: “Although it is an invaluable diagnostic technique, imaging is not employed for assessment of nasal patency, but both rhinomanometry and acoustic rhinometry are widely used for this purpose. The latter two techniques are sensitive and objective, and they provide complementary information on patency…

Acoustic Reflectometry and Endotracheal Intubation

Anesthesia and Analgesia, 1996

Authors: D. M. Eckmann, PhD, JD, R. Glassenberg, MD, N. Gavriely, DSc, MD

Conclusion: “As an adjunct to physical examination, acoustic reflection measurements may provide a simple method to identify difficult-
to-intubate and potential failed endotracheal intubation patients not identified by physical examination and relevant medical history alone.”

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…

Is Area of the Retroglossal space Differently Affected by Posture in Apneic and Nonapneic Snorers?

European Respiratory Journal, 1995 Authors: A. Monnier, B. Lousis, F. Lofaso, l. Gilain, C. Van Surell, D. Touchard, A. Harf, J. Fredberg and D. Isabey Conclusion: “In conclusion, the present acoustic results do not reveal geometrical differences between apneic and nonapneic which could have been masked in previous acoustic studies. Above all, our results demonstrate…
