The frontal lobe of the brain fills the anterior cranial fossa.
The last fossa, named the posterior cranial fossa, contains the cerebellum.
The lesser wing of the sphenoid bone(ala minor)forms the dorsal boundary of the anterior cranial fossa.
With injuries of the posterior cranial fossa, damage to the bones covering the cerebellum is observed.
Eventually, the tumor may invade the intratemporal fossa and the middle cranial fossa.
Fractures of the anterior cranial fossa are accompanied by bone injuries that cover frontal lobes;
It contributes to the moulding of the orbit, nasal cavity, nasal septum andthe floor of the anterior cranial fossa.
A less common dissemination route towards the middle cranial fossa is the perineural route, via foramen rotundum.
Anterior Cranial Fossa The anterior cranial fossa comprises a holey plate at the center, the so called cribriform plate lamina cribrosa.
The frontal bone also forms the floor of the anterior cranial fossa, in which the frontal lobe of the brain resides.
Cribriform plate  comprises numerous openings through which the olfactory fibers from the nasal cavity pass through to the anterior cranial fossa.
It is separated from the middle cranial fossa by the dorsum sellae and the upper edge of the petrous bone.
These authors do not recommend endonasal approach on stage IV andon some cases of stages III with greater extension to mid cranial fossa.
In the center of the middle cranial fossa it forms the pituitary fossa in which the pituitary gland sits.
The sphenoid bone Â- This is an important bone that forms the anterior and medial floor of the middle cranial fossa, and houses the pituitary gland within its body sella turcica.
CT of temporal bones in axial plane, clearly showing a density velamentum of soft parts, engaging in the antrum of the left mastoid in attic area, endangering the ossicular chain,with bone erosion protruding the posterior cranial fossa.
Objectives: to describe a novel approach through the middle cranial fossa for exposing the cochlear basal turn for cochlear implantation.
In 2008, Montoya et al. published a case of a 75-year old man with a temporal bone IMT, with skull base invasion and involvement of cranial nerves VI, X, XI e XII. The patient was submitted to tympanomastoidectomy andhad dura mater erosion and posterior cranial fossa invasion, and he died afterwards.
 These bones also form the posterior two thirds of the floor of the middle cranial fossa, as well as the anterior surfaces of the posterior cranial fossa.
Multislice computed tomography demonstrated the presence of a subtle, apparently vascular, tube-shaped structure originating from the vertical segment of the internal carotid artery at right, with an ascending course along the cochlear promontory, crossing the oval window Figure 1,passing adjacent to the stapes crura Figure 2 towards the middle cranial fossa, with enlargement of the anterior tympanic segment of the facial nerve Figure 3.
The site where the anterior ethmoidal artery penetrates the cranial fossa is particularly interesting, considering that this is the thinnest and less resistant region of the whole skull base.
With the emergence of the endoscopic expanded endonasal approach, areas such as the clivus, the petrous bone,the middle cranial fossa and the infratemporal fossa became accessible.
Different classification have been proposed for the anterior cranial fossa encephaloceles that, in a simplified way, are divided into two major groups, according to the herniation topography.
Most usually, areas of bone destruction in the skull base are the clivus,the foramen lacerum and the middle cranial fossa, around the sphenoid sinus floor and foramen jugularis Figure 6.
Similarly to the onset of complications,the close relation between paranasal sinuses, cranial fossa and orbit expose the orbital and cranial contents to the risk of damage during paranasal sinuses surgery, especially of ethmoidal sinuses.
It may also be inferred that the abnormal dural enhancement of the cavernous sinus at this side is most probably caused by orbital involvement rather than by the cerebral abscess of the anterior cranial fossa, given the known direct pathway of infection dissemination from the orbit to the cavernous sinus in such situations.
Hence, our group has treated patients with craniofacial fibrous dysplasia under the following philosophy:lesions in the anterior skull base(anterior and middle cranial fossa) are treated with radical surgical intervention, whereas lesions in the posterior skull base(posterior fossa) have been treated with conservative surgery because of the difficulty in achieving complete tumor removal/reconstruction.
Open surgeries include partial rizothomy andmicrovascular decompression that involve the exploration of the posterior cranial fossa involving the increased risk of severe complications for example, meningitis and death.
It has greater and lesser wings,with the greater wings forming the floor of the middle cranial fossa, and the lesser wings forming the most posterior region of the anterior cranial fossa.
The surgery procedures in the Ménière's disease may be: 1. decompressive;2. vestibular neurectomies with access by the middle cranial fossa, retrosigmoid or retrolabyrinthic; 3. labyrinthectomy by transmeatal access or translabyrinthic.
