1 Variations in the shape of the superior compartment of the FSDP due to variations in the marginating air cells. Variations in the shape of the superior compartment of the FSDP due to variations in the marginating air cells. A, No marginating air cells. B and C, Marginating air cells anteriorly and posteriorly encroach upon the lower portion of the superior compartment and its junction with the inferior compartment. In B, the uncinate process obscures the ethmoid infundibulum. Removing the uncinate process (C) exposes the course and configuration of the ethmoid infundibulum. David L. Daniels et al.
