The inferior turbinate is located at the lowermost part of the lateral wall of the nasal cavity and consists of the inferior turbinate bone and the mucous membrane covering the surface of the turbinate and the submucous tissue. There are three turbinates in the lateral wall of the nasal cavity from the bottom to the top: inferior turbinate, middle turbinate, and superior turbinate, the largest being the inferior turbinate. When you look in the mirror, you can see two small round balls inside the nasal cavity, which are usually the inferior turbinates of the human nose. The inferior turbinates have a particularly important role to play in maintaining resistance on both sides of the nasal cavity, helping to regulate airflow and effectively keep breathing open, as well as warming, humidifying and cleaning the inhaled air. Rhinitis can lead to enlargement and hypertrophy of the inferior turbinates, resulting in a certain degree of nasal congestion, so enlarged or hypertrophied inferior turbinates are a sign of rhinitis. Through the treatment of rhinitis, the enlarged or hypertrophied inferior turbinates can be reduced to a normal level, and if necessary, the inferior turbinates can be reduced through inferior turbinate surgery to improve the symptoms of nasal congestion.
