What structures make up the base of the nose?

The structures that make up the base of the nose primarily include the lower lateral cartilages, also known as alar cartilages. These cartilages play a crucial role in defining the shape and structure of the nostrils and contribute to the overall appearance of the nasal tip.

The lower lateral cartilages are flexible and allow for movement and shape when breathing, which is essential for proper respiratory function. They form a significant part of the nasal framework and support the skin and soft tissues of the nose. Understanding their role helps in comprehending various procedures in rhinoplasty and other cosmetic or reconstructive interventions involving the nasal area.

In contrast, the upper laterals are positioned above the lower laterals and contribute to the middle third of the nose, while the nasal bones form the bridge of the nose, which is distinct from the base. The alar cartilages are important in the broader context of nasal anatomy but are distinct from the lower lateral structures.
