Definition of Turbinates


Updated June 24, 2014

Written or reviewed by a board-certified physician. See About.com's Medical Review Board.

Definition: Turbinates, which are also called nasal concha, are a network of bones, vessels and tissue within the nasal passageways that are responsible for warming, humidifying, and filtering the air we breathe. They also direct airflow within the nasal passageways. If the vessels within the turbinates become swollen due to a cold or allergies, it can cause severe congestion. If this becomes a long-term problem some doctors will surgically reduce the turbinates. Enlarged turbinates can also be responsible for sleep apnea.
Also Known As: nasal concha
