The ethmoid bulla (or ethmoidal bulla) is a rounded elevation upon the lateral wall of the
ethmoidal air cells (which open into the nasal cavity upon or superior to the ethmoidal bulla[2]: 374 [3]).[2]: 377 It varies significantly based on the size of the underlying air cells.[4]
Structure
The ethmoid bulla is formed by is the largest and least variable of the middle ethmoidal air cells.[3] 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 (sources differ) inferior[5][6][1]/anterior[2]: 374 to the ethmoid bulla. The maxillary sinus also opens below the bulla.[5][6]
Development
The ethmoid bulla begins to develop between 8 weeks and 12 weeks of gestation.[6]
