Lateral nasal cartilage

The lateral nasal cartilage is a vital structure in the human nose, contributing significantly to its shape and function. It is one of the several cartilages that form the framework of the nose, providing support and maintaining the patency of the nasal passages.

Anatomy

The lateral nasal cartilage is a paired structure, meaning there is one on each side of the nose. It is situated below the nasal bone and above the greater alar cartilage. The lateral nasal cartilage is triangular in shape and connects with the septal cartilage medially and the greater alar cartilage inferiorly.

Function

The primary function of the lateral nasal cartilage is to support the lateral walls of the nose. This support is crucial for maintaining the shape of the nose and ensuring that the nasal passages remain open for proper airflow. The lateral nasal cartilage also plays a role in the aesthetic appearance of the nose, contributing to its overall contour and profile.

Clinical Significance

Damage or deformity of the lateral nasal cartilage can lead to functional and cosmetic issues. Trauma to the nose, such as from a nasal fracture, can disrupt the integrity of the lateral nasal cartilage, potentially causing nasal obstruction or a change in the shape of the nose. Surgical procedures, such as rhinoplasty, often involve modification of the lateral nasal cartilage to achieve the desired aesthetic outcome.
