When lymphatics of the cribiform plate are blocked, hindering CSF absorption, intracranial pressure (ICP) is raised.
But if their conduit through the cribiform plate closes, smell loss will be irreversible.
OSNs of laboratory animals may be induced to die in vivo by experimentally manipulative methods that include olfactory bulbectomy, transection of the olfactory nerve at the cribiform plate, and intranasal exposure to chemicals known to be toxic to the OE, such as zinc sulfate and methyl bromide (Cowan and Roskams 2002).

The type of tumors observed had papillary adenomatous patterns and ductal carcinomas with cribiform pattern.
Most tumors induced in young virgin rats can be classified within three major groups: intraductal papillomas, composed of a hyperplastic epithelium; papillary carcinomas, which may be composed of epithelial cells with varying degrees of cytologic atypia, growing in solid, papillary adenomatous patterns; and ductal carcinomas with cribiform pattern.
If intracranial extension is present, it classically occurs through the foramen cecum or cribiform plate and attaches extradurally to the falx cerebri.

No definitive areas of bony deficiency in the cribiform plate were seen, but there was a questionable defect on the roof of the left ethmoid sinus (figure 1,A-C).
