Nasal dyspnea: the place of rhinomanometry in its objective assessment

Abstract

Background: "Nasal dyspnea" describes the common symptom of nasal airway obstruction, which usually is assessed subjectively. Objective, quantitative methods are needed to assess the nasal airway adequately.

Methods: Rhinomanometry, in use for >30 years, was reviewed.

Results: No other symptom of rhinitis can be measured as objectively and accurately as that of nasal obstruction. Determinations by rhinomanometry are precise, usually better than 5%. Most rhinomanometers meet the published requirements of standardization by the International Rhinologic Society. An improved system for scoring symptoms of nasal dyspnea is suggested. Rhinomanometry, potentially a gold standard for the objective measurement of obstructed nasal airflow, has a proven place in the selection of patients for septal and nasal valve reconstruction.

Conclusion: Recommendations are given for extension of the standards to account for the near universal computerization of equipment. Miniaturization of equipment will increase its application to trials of drugs for rhinitis.
