This study aims to demonstrate a decrease with normalization of nasal resistance in the forward decubital position and with an intra-nasal stent in patients with nasal obstruction.


All patients consulting for nasal obstruction at night and who have functional nasal test with pathological resistance in decubitus position are included.

Functional nasal test (non invasive tests) will be performed before and after intranasal introduction of a stent: anterior rhinomanometry to measure nasal function by the measure of resistance and acoustic rhinometry to measure the geometry of nasal fossa by the measure of minimal sectional cross area sitting, after 30 minutes of decubitus then new measurements with a stent in decubitus position in each nostril .
