“…The foramina allow the olfactory nerves to course through toward the olfactory bulb [ 3 - 5 ]. The lateral laminae of the cribriform plate are the thinnest portions of the ethmoid roof, making the cribriform structure anatomically delicate to increased intracranial pressure [ 2 , 6 ].…”

“…Congenital herniation is thought to be due to an error with the development of the mesoderm, whereas acquired forms of brain herniation are secondary to traumatic or iatrogenic origins. Herniation through the anterior cranial fossa and through the cribriform plate requires rigid reconstruction with a multilayer repair being necessary in these patients in order to avoid spinal fluid leakage [ 2 ].…”

“…A theory suggested by Dange et al proposed that chronically sustained intracranial hypertension upon the cribriform plate resulted in erosion [ 2 ]. Their study presented the case of a space-occupying lesion (an extra-axial mass) which resulted in the progressive destruction of the cribriform plate secondary to increased intracranial pressure.…”

“…Anatomical variations observed in the cribriform plate may also lead to the plate becoming weakened, thus allowing herniation to follow. These variations include a lack of occlusion of the foramina along the olfactory fibers in the cribriform plate, a persistent cranial pharyngeal canal, the presence of a fistula in the embryological remnants of the olfactory bulb lumen, and meningeal dysplasia at the site of the olfactory nerves [ 2 ].…”

“…Normally, the brain will try to counteract the added volume by decreasing volume elsewhere in order to maintain equilibrium; shifting CSF or reducing venous blood flow may accomplish this, i.e., the Monro-Kellie doctrine. The herniation of brain tissue is more commonly observed traversing the foramen magnum, tentorial incisura, and subfalcine space [ 1 - 2 ].…”

Herniations of the brain and/or meninges through an opening of the skull often occur through the foramen magnum, e.g., Chiari malformations and encephaloceles. The herniation of brain matter through the cribriform plate is a rare incident and has not been reported frequently. The presence of such an occurrence still requires attention and anatomical understanding. This review will examine the potential causes of cribriform plate herniation and its distinguishability to nasal encephaloceles. The sloping of brain tissue toward potential space/opening in response to elevated pressures in the cranium to accommodate for the added pressure are features seen in herniation. The presence of a pedicle and stalk seen in an encephalocele define its characteristics, which are not visible in a ‘classical’ herniation. Cerebrospinal fluid (CSF) fistula commonly occurs at the cribriform plate, and due to the structural weakness, a pathway is formed. This is often seen in conjunction with meningoceles. Delineating between herniation and encephaloceles is important for both clinicians and neurosurgeons.
