Lateral nasal cartilages

Lateral nasal cartilages

The lateral nasal cartilages are a pair of cartilages located in the nose that play a crucial role in the structure and function of the nasal anatomy. These cartilages are part of the nasal skeleton and contribute to the shape and stability of the nasal cavity.

Anatomy

The lateral nasal cartilages are situated on either side of the nasal septum, which divides the nasal cavity into two nostrils. They are connected to the upper lateral cartilages and the lower lateral cartilages, forming a framework that supports the nasal dorsum and the nasal tip. The lateral nasal cartilages are composed of hyaline cartilage, which provides both flexibility and strength.

Function

The primary function of the lateral nasal cartilages is to maintain the shape of the nose and support the nasal passages. They help to keep the nasal airways open, facilitating proper respiration and olfaction. Additionally, these cartilages play a role in the aesthetic appearance of the nose, contributing to its overall contour and profile.

Clinical Significance

Damage or deformities in the lateral nasal cartilages can lead to various medical conditions, such as nasal obstruction, deviated septum, and nasal valve collapse. Surgical procedures, such as rhinoplasty and septoplasty, often involve the lateral nasal cartilages to correct structural issues and improve both function and appearance.
