Incompetence of Nasal Valve

Brief summary

Several nasal dilators are currently commercially available, and can be applied endonasally (Airmax°, Nozovent and Nasanita°) or externally (Breath Right°). An objective comparison between these dilators has not been made so far, and would help the clinicians to advise the use of any of these dilators. From clinical experience, endonasal dilators are well supported and improve breathing better than the external dilators

Inclusion criteria

Patients with nasal obstruction due to external nasal valve problems and with positive Cottle sign. Age \> 18 and \< 60 years. Ability to give reliable information and written informed consent.

Exclusion criteria

Patients with nasal obstruction due to other endonasal anatomic deformities besides external nasal valve dysfunction. Patients with rhinosinusitis and/or nasal polyps evaluated by nasal endoscopy. Patients with chronic lower airway disease like severe asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis and/or other conditions that interfere with the generation of a reliable Peak Nasal Inspiratory Flow (PNIF) result.
