Recent clinical findings of research at Trondheim University Hospital suggest that surgical correction of the nose septum in addition to volume reduction of the nose cavity may be beneficial in patients who suffer from both nose obstruction and obstructive sleep apnea syndrome(data not yet published).

This study aims to compare nose obstruction prevalence in sleep apnea patients and the general population

Primary Outcome Measures:
  • patient reported nasal obstruction [ Time Frame: 1 week ] [ Designated as safety issue: No ]

  • objective nasal obstruction [ Time Frame: 1 week ] [ Designated as safety issue: No ]
    measured by acoustical rhinometry and Peak Nasal Inspiratory Flow (PNIF).
