Role of acoustic rhinometry in assessing rhinoseptoplasty candidates

Abstract

Introduction: Nasal obstruction is difficult to evaluate, particularly in candidates to rhinoseptoplasty. One of the methods available to assess nasal obstruction is acoustic rhinometry, which yields an estimate of nasal cross-sectional area and nasal volume as a function of distance from the nostrils. Aim: The aim of this study was to compare results from acoustic rhinometry to those obtained using other nasal obstruction evaluation methods. Alternative methods used were: Anterior rhinoscopy, nasal endoscopy, rhinomanometry, and subjective sensation of nasal obstruction as reported by the patient. Material and method: A prospective, descriptive study design was used, evaluating a total of 26 patients. Results: A good association was found between the values produced by acoustic rhinometry and those obtained by rhinomanometry and the subjective sensation of nasal obstruction reported by patients. On the other hand, the association between acoustic rhinometry and both anterior rhinoscopy and nasal endoscopy was weak. Conclusion: Acoustic rhinometry is an useful tool for assessing nasal obstruction in rhinoseptoplasty patients. However, it does not surpass a good clinical evaluation.
