Functional impairments of nasal breathing are generally associated with an external malposition of the nose caused either by an accident or congenital malformations. Generally the outer nose is visibly crooked, meaning it can be straightened at the same time. Similarly, it is not only crookedness in the septum but also severe swelling in the nasal concha, nasal polyps or chronic mucosal changes in the sinuses that can hinder nasal breathing or cause problems with smell, headaches, recurring infections of the upper airways or increased snoring at night. Minimally invasive procedures mean the complaints can be alleviated pain-free with just a light tamponade over one night.
