The axons of olfactory neurons narrow to a diameter of approximately 200 nm and become tightly packed where they pass through the cribriform plate pores (DeLorenzo 1957; Plattig 1989).
These defects can now easily be accessed via endoscopic transnasal techniques, especially the cribriform plate, the roof of the ethmoid sinuses and the sphenoid sinus.
Intracranial extension was found in 6 patients, and the usual mode was through the cribriform plate to the anterior cranial fossa.
Magnetic resonance imaging (MRI) demonstrated a contrast-enhancing mass within the anterior ethmoid air cells on the left, with a small amount of intracranial extension through the cribriform plate (figure 2).
On dissecting the ethmoid roof, there was erosion of the cribriform plate and adhesion of the mass to the dura but no erosion of brain tissue.
Imaging revealed the presence o fan ethmoidochoanal polyp, as well as a fracture of the posterior cribriform plate and a small associated meningocele.
The recurrence was excised, but 4 years later, the patient experienced a second recurrence; in this case, the tumor had invaded the cribriform plate and extended to the anterior cranial fossa.
The length of the septum was measured in the coronal plane from the cribriform plate superiorly to the hard palate inferiorly.
Choanal polyp originating from the cribriform plate.
Magnetic resonance imaging (MRI) obtained the same day confirmed the extension of the enhancing tumor across the cribriform plate and involvement of the anteroinferior aspect of the left frontal lobe--findings that had not been conspicuous on FDG-PET/ CT (figure 2).
Bony erosion of the anterior cribriform plate and left lamina papyracea was also noted on review of the films.
