Our Minneapolis and St. Paul area nose doctors treat a variety of nose and sinus issues. The nose is the primary means of bringing warm, humidified, clean air into the lungs. It is the organ that filters out particles and is the first-line of immunologic defense by bringing infectious material into the mucous membranes with immunoglobulins. The nose also presents molecules to olfactory nerves which provides our sense of smell. While a wide open nose makes it easier to breathe, some restriction of airflow allows us to better fill our lungs. Partial nasal obstruction caused by the septum and turbinates cause turbulent airflow, which helps the nose filter particles before they reach the lungs. However, a deviated septum and enlarged turbinates can lead to excessive nasal obstruction. This is not only uncomfortable, but leads to less efficient, non-physiologic mouth breathing.
