The important lymphatics of the cribiform plate area are accessed in this way and deep breathing potentiates lymphatic flow in the thoracic duct.
The cribiform plate, accessed via medial eye puncta and nasal areas, is treated first, then the zygomatic tract, auricular nodes and mastoid process.
It drains via the cribiform plate, transporting antigens within it to deep cervical lymphatic vessels and nodes(1,16).
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).
High-resolution computed tomography (CT) of the anterior cranial fossa demonstrated air in the cranial cavity, indicating a fracture or breach of the cribiform plate (figure 1).
Cartilage manipulation during septoplasty and subsequent insertion of the splints might have led to destabilization of the superior attachment of the middle turbinate to the cribiform plate in our patient.
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.
(6,7) The increasing use of powered microdebrider instruments along the skull base and thin bones of the cribiform plate and ethmoid sinus may be associated with a greater incidence of pneumocephalus after FESS.
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).
