The ethmoid labyrinth. An anatomical and radiological study.

After an osteological description of the ethmoid labyrinth, the authors examine the radiological techniques which best display the topography, interrelation and configuration of the ethmoid cells. On the basis of their observations they conclude that standard radiographic examinations cannot provide an adequately clear anatomical-radiological representation of these cells and must therefore be supplemented with polytomography and computerized tomography.
