Nasal concha

Nasal concha

The Nasal concha, also known as turbinates, are long, narrow and curled bone shelves that protrude into the breathing passage of the nose. They are responsible for warming, humidifying, and filtering the air prior to it reaching the lungs.

Structure

The nasal concha consists of three parts: the superior nasal concha, the middle nasal concha, and the inferior nasal concha. Each of these parts plays a crucial role in the functioning of the respiratory system.

Superior Nasal Concha

The superior nasal concha is the smallest and most superiorly located of the three nasal conchae. It is a part of the ethmoid bone.

Middle Nasal Concha

The middle nasal concha, also part of the ethmoid bone, is located below the superior nasal concha.

Inferior Nasal Concha

The inferior nasal concha is an independent bone of the skull, unlike the superior and middle nasal conchae. It is the largest and most inferiorly located of the three nasal conchae.

Function

The primary function of the nasal concha is to increase the surface area of the nasal cavity. This aids in warming and humidifying the air that passes through the nasal passages on its way to the lungs. The conchae also help to filter the air, removing any dust or small particles that may be present.

Clinical significance

Abnormalities or injuries to the nasal concha can lead to a variety of health issues, including nasal congestion, sinusitis, and sleep apnea. Treatment options can range from medication to surgery, depending on the severity of the condition.
