Endoscopically resectable anatomical areas include the following: Entire anterior cranial base from cribriform plate to planum sphenoidale.Dura, olfactory bulbs and lamina papyracea.Nasopharynx, clivus and odontoid process can now be reached, limited inferiorly at the nasopalatine line.Laterally, the pterygopalatine and infratemporal fossa can be reached, with the transpterygoid approach affording additional access to the petrous temporal bone, Meckel's cave and middle cranial fossa.

The infratemporal fossa is the area that lies anterolateral to the lateral pterygoid muscle containing fat and muscle (Figure 1.21c). It is usually invaded via the pterygomaxillary fissure or through the lateral pterygoid muscle.

Secretomotor – preganglionic fibres from the inferior salivary nucleus (glossopharyngeal nerve – tympanic branch of IX – lesser petrosal nerve – otic ganglion – post-ganglionic fibres in the auriculotemporal nerve). The otic ganglion is closely applied to the mandibular nerve beneath the foramen ovale in the infratemporal fossa.

This report demonstrates the importance of personalized surgical procedures, which are determined by surgical objectives, patient anatomy, and the location and extent of tumor involvement. In our institute, comprehensive resection through modern surgical approach is the preferred treatment to minimize adverse reactions for patients with long life expectancy. Fisch U developed the infratemporal fossa approach and first presented it in 1977 [16]. This approach allows for a wider view of the lateral skull base and, thus, safer and less constricted access to the tumor in this area [5]. From the clinical data, we can see that TBC mostly originated in the middle ear mastoid area, mainly concentrated in the sublabyrinthine area, and easily extended to the jugular foramen area (80%), less invasion of the labyrinthine area, which has a good indication for the operation of infratemporal fossa approach. Infratemporal fossa approach was used in all 10 patients and got good results. All patients survived without evidence of disease at a median time of follow-up of 28.8 months (range from 6 to 78 months). One patient was lost to follow-up at 12 months. Postoperative radiotherapy should be considered in subjects with high-grade diseases, especially for those with known residual tumors or extensive primary involvement regardless of the extent of resection.

The pterygopalatine or sphenopalatine fossa is a passageway between many major compartments of the skull and is thus a critical location for tumor spread. This fossa is a located in the basilar region of the skull and is bounded medially by the palatine bone, posteriorly by the pterygoid process of the sphenoidal bone, and anteriorly by the posterior wall of the maxillary sinus. It has six communications to major compartments of the skull, communicating medially to the nasal cavity via the sphenopalatine foramen, laterally to the infratemporal fossa via the pterygomaxillary fissure, anteriorly to the orbit through the inferior orbital fissure, posteriorly and superiorly to Meckel’s cave and the cavernous sinus via the foramen rotundum, posteriorly and inferiorly to the middle cranial fossa via the vidian canal, and inferiorly to the palate through the greater and lesser palatine canals. As this fossa has direct access to the nasal cavity, intracranial space, orbit, and cavernous sinus, it is a common site for direct invasion and perineural spread of disease and can present with involvement of any combination of the aforementioned compartments.15 In our patient, the carcinoma most likely spread from the nasal cavity to the sphenopalatine fossa, and then extended to the infratemporal fossa, cavernous sinus, and orbit.
Isolated cranio-orbitofacial neurofibroma mimicking vascular malformation

Magnetic resonance imaging (MRI) with gadolinium revealed a large multi-lobulated mass in the right superior orbit with insinuation into multiple anatomic compartments (Figure 2A). The mass extended posteriorly through the orbital apex, without significant compression of the optic nerve, and into the right cavernous sinus with medial displacement of the internal carotid artery. Inferiorly, the mass extended into the infratemporal fossa via the sphenopalatine foramen, with extensive involvement of the maxillary sinus and retro-maxillary space (Figure 2B). Additional lesions were noted inferior to the right pterygoid muscles, and in the right occipital upper neck region, though it was not clear if these lesions were contiguous. The findings were felt to be consistent with a macrocystic lymphatic malformation.
