Turbinates, also known as nasal conchae, are shell-shaped structures within the nasal passages made of bones, blood vessels, and soft tissue. The nasal cavity houses three pairs of turbinates: the inferior, middle, and superior turbinates.Â
- Inferior turbinates are the largest and are located at the bottom of the nasal passage.Â
- Middle turbinates are located above the inferior turbinates.Â
- Superior turbinates are the smallest and are situated at the top of the nasal cavity.Â
These turbinates are covered with a mucosal lining that naturally swells in response to the nasal cycle, lying down, allergens, or irritants.Â
Most of the airflow in the nose passes between the middle and inferior turbinates. When these turbinates become enlarged due to inflammation or other causes, they can obstruct nasal airflow and lead to breathing difficulties.
