Inferior turbinate

Inferior Turbinate

The Inferior Turbinate (also known as the Inferior Nasal Concha) is one of the three pairs of turbinates in the human nose. The turbinates are long, narrow, curled bone shelves that protrude into the breathing passage of the nose. The inferior turbinate is the largest and lowest of the turbinates.

Anatomy

The inferior turbinate extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll. It has a convex and a concave side, the convex side forming part of the lateral wall of the nasal cavity, and the concave side forming one of the nasal meatuses.

Function

The primary function of the inferior turbinate is to regulate airflow and aid in the warming, humidification, and filtration of the air inhaled through the nostrils. It also plays a role in the sense of smell, as it is covered in a mucous membrane that contains smell receptors.

Clinical significance

Enlargement of the inferior turbinate, known as Inferior Turbinate Hypertrophy, can lead to chronic nasal obstruction and difficulty in breathing. This condition can be treated through various surgical procedures, including Inferior Turbinate Reduction.
