Nasal cartilage

Nasal Cartilage

The Nasal Cartilage is a significant component of the human nose that contributes to its shape and structure. It is primarily composed of hyaline cartilage, a type of connective tissue that is both flexible and resilient.

Structure

The nasal cartilage is divided into several parts, each with its unique role and structure. These include the septal cartilage, lateral nasal cartilage, and the alar cartilage.

Septal Cartilage

The septal cartilage forms the anterior part of the nasal septum, which separates the left and right nasal cavities. It is a flat, quadrangular piece of cartilage that is attached to the perpendicular plate of the ethmoid bone and the vomer.

Lateral Nasal Cartilage

The lateral nasal cartilage is situated directly below the nasal bone and above the greater alar cartilage. It contributes to the shape of the upper part of the nose.

Alar Cartilage

The alar cartilage forms the lower part of the nose. It consists of two parts: the medial crus, which shapes the nostril's inner wall, and the lateral crus, which shapes the nostril's outer wall.

Function

The primary function of the nasal cartilage is to provide structure and shape to the nose. It also plays a crucial role in the process of respiration by ensuring the nostrils stay open for air passage.

Clinical Significance

Damage or deformities to the nasal cartilage can lead to conditions such as a deviated septum or rhinophyma. These conditions can cause breathing difficulties and may require surgical intervention, such as rhinoplasty or septoplasty, to correct.
