Cartilage is cartilage tissue, which consists of chondrocytes and intercellular substance. The matrix in cartilage is in a gel state and has great toughness. Cartilage is a connective tissue that plays a supporting role. There are no blood vessels and lymphatic vessels in cartilage, and nutrients penetrate into the intercellular space from the blood vessels in cartilage membrane, thus nourishing bone cells.

Hypertrophy of alar:

The hypertrophy of the alar is an aesthetic defect of the nose, which is more common in yellow people and black people. It is also very common in clinic, often coexisting with saddle nose and blunt nose. When it is serious, it often gives people a rude or dull feeling.

The edge of the alar should be a harmonious arc, not too high, too low, too straight or asymmetrical. When the alar droops, the alar hypertrophy can be manifested as the front, back or all alar edges drooping, and the side view can cover the columella, forming a false columella invagination deformity, which should be distinguished from the true columella invagination.
