In 1997 Kunkel and Hochban (35) utilized the acoustic rhinometry
concept introduced by Hilberg et al in 1989 (36) to evaluate the effect of maxillary movement on the nasal volume.
In the study, 114 adults presenting complaints of CRS-related symptoms completed a Sino-Nasal Outcomes Test 20 (SNOT-20) and underwent an endonasal examination, acoustic rhinometry
and smell testing.
When used on the nose, this technique is termed acoustic rhinometry
and does not provide information regarding the pharyngeal cross section.
Evaluation of the nasal cavity by acoustic rhinometry
PARTICIPANTS AND MEASUREMENTS: Twenty-nine volunteers provided symptom reports, ocular electromyograms, measurement of eye tear film break-up time, vital staining of the eye, nasal lavage, acoustic rhinometry
, transfer tests, and dynamic spirometry.
Ear, nose, and throat specialists in the Department of Otorhinolaryngology are using the Acoustic Rhinometry
System to evaluate patients who have difficulty breathing because of nasal blockage.
was used to measure the minimum cross-sectional area (MCSA) and the volume of the nasal cavity on both the left and right sides before and after laryngectomy.
evaluation (A1 Acoustic Rhinometer, GM Instruments, Kilwinning, Scotland); and
After 10 minutes of reaction rime, the degree of mucosal swelling is assessed by either acoustic rhinometry
or anterior rhinomanometry.
Unilateral and bilateral effects of nasal septum surgery demonstrated with acoustic rhinometry
, rhinomanometry, and subjective assessment.
Likewise, acoustic rhinometry
is useful in making postoperative comparisons by quantifying changes in the cross-sectional area of the nasal cavity.
We evaluated the intrasession and intersession reliability of acoustic rhinometry
in measuring nasal cross-sectional areas in 10 subjects.
