Information about Ethmoidal Bulla

Lateral wall of nasal cavity; the three nasal conchæ have been removed. (Bulla ethmoidalis is labeled at center top.)
Latinbulla ethmoidalis
subject #223 995
On the lateral wall of the middle meatus is a curved fissure, the hiatus semilunaris, limited below by the edge of the uncinate process of the ethmoid and above by an elevation named the bulla ethmoidalis; the middle ethmoidal cells are contained within this bulla and open on or near to it.

The bulla ethmoidalis is caused by the bulging of the middle ethmoidal cells which open on or immediately above it, and the size of the bulla varies with that of its contained cells.
