Alar cartilage is a small, flexible structure located in the nose. It is part of the nasal framework and helps shape the nostrils. This cartilage plays a crucial role in maintaining the structure of the nasal passages and supports the surrounding tissues. In addition to its structural function, alar cartilage contributes to the overall appearance of the nose. It works in conjunction with other components, such as the nasal septum and nasal bones, to create a balanced and functional nasal anatomy. Proper development of alar cartilage is important for both breathing and aesthetic reasons.
