The middle nasal concha is a bony structure located within the nasal cavity. It is one of three conchae, which are curved bones that help to filter and humidify the air we breathe. The middle nasal concha is situated between the superior and inferior nasal conchae and plays a role in regulating airflow and supporting the mucous membranes. This structure is part of the ethmoid bone, which is crucial for the formation of the nasal cavity and the orbit of the eye. The middle nasal concha also contributes to the drainage of the paranasal sinuses, helping to maintain proper sinus function and overall respiratory health.
