Rhinomanometry measures air pressure and the rate of airflow in the nasal airway during respiration. These measurements are then used to calculate nasal airway resistance. Rhinomanometry is intended to be an objective quantification of nasal airway patency.
Acoustic rhinometry is a technique used to assess the geometry of the nasal cavity and nasopharynx and for evaluating nasal obstruction. The technique is based on an analysis of sound waves reflected from the nasal cavities.
Both techniques are proposed for use in comparing decongestive action of antihistamines and corticosteroids. These techniques are also proposed for assessment of an individual prior to or following nasal surgery. Testing is generally done in an outpatient setting.
Rhinomanometry and/or acoustic rhinometry for the diagnosis of all nasal conditions is considered investigational.
Any specific products referenced in this policy are just examples and are intended for illustrative purposes only.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
Published scientific evidence in the form of well-designed studies in peer review journals is lacking regarding the utilization of rhinomanometry and acoustic rhinometry in clinical management. There is no evidence that these techniques are more clinically relevant or accurate compared to self-assessment and self-reporting.
