Nose is the normal respiratory organ of the human body and provides heating, humidification of the air that we inhale and filters the foreign substances, allergens and microorganisms inside the air. Oxygen found in the respiratory air can be transferred to the blood circulation better in the lungs when the air is heated and humidified in the nose.
The resistance against the air flow inside the nose during respiration contributes to the good widening of the lower respiratory tract and lungs (naso-pulmonary reflex).
Lower nasal turbinates play an important role in the functioning of the nose. Lower turbinates (concha), containing rich vasculatory content in the tissues under their mucosa, adjusts the heating, humidification and filtering of the respiratory air according to the properties of the environmental air and they also adjust the resistance to be applied against the air flow.
Enlargement of the lower turbinates ( concha hypertrophy ) is one of the main reasons of nasal congestion.
Interventions on lower concha should be performed very carefully due to their critical roles in nasal respiration which is very important for normal body functions and they have to be downsized to provide normal functions but should never be completely removed.
If mouth respiration is performed due to nasal obstruction, then the oxygen of the inhaled air can not be retained sufficiently and the blood oxygen level decreases. Reflexes, developing in response to the perception of decreases in the blood oxygen level by the sensors of the brain and the blood vessels that feed the brain, may cause problems like hypertension, rhythm problems of the heart or heart failure in the long term.
Nasal obstruction also leads problems like frequent throat infections, complaints related to the drying of the throat, sleep disorders and also aggravates snoring and sleep apnea and disrupt the quality of life to a high extent.
