Ethmoidbereichsgerüst
Ethmoidbereichsgerüst is a descriptive term used to denote the structural framework of the ethmoid region—the complex bony and air-filled elements of the skull that form the central part of the nasal cavity and the medial orbital walls. It encompasses the ethmoid bone with its cribriform plate, perpendicular plate, ethmoidal labyrinth (ethmoid air cells), and the superior and middle nasal conchae, together creating support for mucosa, pathways for airflow, and partitions between the nasal and cranial cavities.
Functionally, this framework contributes to nasal airflow conditioning, olfaction (olfactory nerve fibers traverse the cribriform plate),
Clinically, the ethmoid region is important in sinusitis, orbital complications, cerebrospinal fluid leaks, and skull base
