| Anatomical terminology | |
The ethmoid bulla (or ethmoidal bulla) is an elevation on the middle meatus[1] (lateral wall of the of the nose inferior to the middle nasal concha) produced by one ore more middle ethmoidal air cells which open into the nasal cavity upon or above the ethmoidal bulla.[2] It varies significantly based on the size of air cells.
Structure
It is the largest among the middle ethmoidal cells. The size of the bulla varies with that of its contained cells. The bulla may be a pneumatised cell or a bony prominence found in middle meatus.[citation needed]
Relations
The hiatus semilunaris is situated anterior to the ethmoid bulla.[2] The maxillary sinus also opens below the bulla.[1][3]
Development
The ethmoid bulla begins to develop between 8 weeks and 12 weeks of gestation.[3]
