The anterior cranial fossa is a depression in the cranial base, which primarily supports the large frontal lobes of the cerebral hemispheres. However, in the center of the anterior cranial fossa are small depressions, the olfactory fossae, which support the olfactory bulbs (Figs. 2.1, 2.6, and 2.7).The bulbs represent the first part of the olfactory system within the brain itself.

The authors report their results on patients showing anterior cranial fossa fractures; clinical data, surgical indications, and results are reported and critically analyzed. Methods From 1991 to 2010, 223 patients were admitted in our institution with diagnosis of anterior cranial fossa fracture. Fractures were classified as type A—fracture.

The anterior cranial fossa comprises a holey plate at the center, the so called cribriform plate (lamina cribrosa). The approximately 20 cribriform foramina serve as a passageway for the olfactory nerves to the olfactory mucosa in the nasal cavity.. Both the optic nerve and the ophthalmic artery pass through the optic canal which is centrally located on the sphenoid bone.

The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain. In this article, we shall look at the borders, contents and clinical correlations of the anterior cranial fossa.

The anterior cranial fossa (ACF) is a complex anatomical region that can be affected by a broad spectrum of pathology. For the surgical treatment of these lesions, many approaches have been described, each of them with different scope and potential surgical complications, often associated with significant morbidity.

The anterior cranial fossa is a depression in the floor of the cranial base which houses the projecting frontal lobes of the brain. It is formed by the orbital plates of the frontal, the cribriform plate of the ethmoid, and the small wings and front part of the body of the sphenoid; it is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of.

A cranial fossa is formed by the floor of the cranial cavity . There are three distinct cranial fossae: Anterior cranial fossa ( fossa cranii anterior ), housing the projecting frontal lobes of the brain. Middle cranial fossa ( fossa cranii media ), separated from the posterior fossa by the clivus and the petrous crest housing the temporal lobe.

Introduction Skull base fractures are of high importance in neurotrauma. They occur in 3.5 - 24% of head injuries and are often related to brain injury (in 50% of the cases). 70% of the skull base fractures occur in the anterior fossa, 20% in the middle central skull base and 5% in the middle and posterior fossa.
