Cartilage
Lower lateral (alar) cartilages
The paired cartilages of the nasal tip and alae. The alar base sits on the pyriform shelf of the maxilla.
What it is
The paired cartilages of the nasal tip and alae. The alar base sits on the pyriform shelf of the maxilla.
How the Codex reads it
The pyriform region beside the alar base belongs to Uplift, on bone, releasing the nasolabial fold from below rather than filling it.
Safety anatomy
The angular artery passes the alar base; its depth varies.

Every number in this atlas cites the study it came from. The full method, including what this site withholds on purpose, is on sources and method.
This site teaches one level above the Codex's working manual: the architecture is public, the coordinates are not. This page withholds entry points, landmark constructions, volumes and read-to-point routing, exactly as the atlas does. What is shown and what is withheld.
