Nasal Valve Manometry by Differential Pressure Measurements

Abstract

The effects on air flow of a septum spur, located in the nasal valve, are studied both theoretically and experimentally. The analytic investigation on the differential pressure between two points in the nasal valve has been carried out by means of the Bernoulli’s equation in the limit of stationary, non- dissipative and laminar air flow. On the experimental side, the nose and sinus manometer has been adapted with a double-ended probe to make differential manometry measurements. It can be argued that the differential pressure approach is useful to investigate the fluid dynamical anomalies induced by a nasal septum spur.
