"The third basal lamella is unique in being the only complete partition, extending fully from the lateral nasal wall to the lamina papyracea 3. For this reason, the singular term "basal lamella (of the middle turbinate)" refers specifically to this structure. Its morphology is complex and variable; contemporary descriptions favour a multi-segmental characterisation over the traditional L-shape, with the most common configuration - a sigma-concave/convex-horizontal pattern - identified in ~30% of cases in one series 4."
