Turbinate 3... The anterior half of the middle turbinate acts like an awning. It provides a location free from rapid airflow and airborne particles for the anterior sinuses to open into. The space under the middle turbinate is called the middle meatus. The front of the middle turbinate can be mistaken for a polyp on nasal exam. It may be necessary to apply a topical decongestant to visualize the middle turbinate. 1999 Peter Casano
