“…The craniotomy was associated with an orbitozygomatic, orbital, or zygomatic osteotomy in 76, 19, and two patients, respectively, so as to widen the field of view and the working cone, and decrease brain retraction. 39,41,42 Surgical Exposure. A wide extradural exposure of the skull base was created in all patients, beginning at the middle fossa to visualize the foramen ovale (with the mandibular nerve) and the foramen rotundum (with the maxillary nerve), as well as the superior orbital fissure anteriorly (with the ophthalmic nerve and the motor ocular nerves).…”

“…Eighty-one patients also underwent an extradural anterior clinoidectomy to free the optic nerve dural sheath completely and expose the paraclinoid portion of the ICA after its exit from the CS roof. 4,8,9,30,35,39,44 Such an extensive approach permits clear identification of the skull base structures and is supposed to achieve significant devascularization of the meningioma. In fact, this wide approach makes it possible to interrupt the arterial supply, not only from the middle meningeal artery that is coagulated, clipped, and divided at the exit from foramen spinosum, but also from the small arteries passing through the foramen ovale, the foramen rotundum, and the superior orbital fissure along the dural sheaths of the corresponding cranial nerves.…”

“…35 Subtotal removal is also reported to be a source of postoperative bleeding from the tumor bed with associated instances of morbidity and mortality. 5,28 In a re-view of the literature, Sindou and Pelissou 40 found that total removal of the tumor had been achieved in only 50% of cases because of the close relationship of the lesion to the cerebellopontine angle, petrous apex, cavernous sinus, and important cranial nerves. Despite the emphasis on total removal in later series, 31,45 this has not always been possible because of risks to vital structures.…”

Preservation or improvement of cranial nerve function can be achieved through total removal of a trigeminal schwannoma, and skull base approaches are better suited to achieving this goal. The zygomatic middle fossa approach is particularly helpful and safe. It allows extradural tumor removal from the cavernous sinus, the infratemporal fossa, and the posterior fossa through the expanded Meckel cave.

The lateral dural wall of the cavernous sinus is composed of two layers, the outer dural layer (dura propria) and the inner membranous layer. Tumors arising from the contents of the lateral dural wall are located between these two layers and are classified as interdural. They are in essence extradural/extracavernous. The inner membranous layer separates these tumors from the venous channels of the cavernous sinus. Preoperative recognition of tumors in this location is critical for selecting an appropriate microsurgical approach. Characteristics displayed by magnetic resonance imaging show an oval-shaped, smooth-bordered mass with medial displacement but not encasement of the cavernous internal carotid artery. Tumors in this location can be resected safely without entering the cavernous sinus proper by using techniques that permit reflection of the dura propria of the lateral wall (methods of Hakuba or Dolenc). During the last 5 years, the authors have identified and treated five patients with interdural cavernous sinus tumors, which included two trigeminal neurinomas arising from the first division of the fifth cranial nerve, two epidermoid tumors, and one malignant melanoma presumed to be primary. The pathoanatomical features that make this group of tumors unique are discussed, as well as the clinical and radiological findings, and selection of the microsurgical approach. A more favorable prognosis for tumor resection and cranial nerve preservation is predicted for interdural tumors when compared with other cavernous sinus tumors.
