The nasal tip is formed by two arched cartilages with one common leg, resembling a three-legged stool. The upper legs extend above the nostrils, while the lower common leg spans the columella (the fleshy part between the nostrils). Nasal tips vary widely in their width, height, curvature, and overall shape. With a refined nasal tip, these cartilages have a strong bend in the arched region and the tripod legs are straight and strong.
