title: Combined frontotemporal-orbitozygomatic approach for tumors of the sphenoid wing and orbit.
abstract: An extension of a combined frontotemporal and orbitozygomatic exposure was developed to remove 8 hyperostosing invasive sphenoid wing meningiomas (Group 1) and 11 complicated intraorbital tumors with and without intracranial extension (Group 2). Two separate bone flaps were created: a free frontotemporal-sphenoidal (pterional) bone flap and en bloc removal of the superior and lateral orbital margins with attached zygomatic arch. Cranio-orbital reconstruction was performed using the inner table of the pterional bone flap. Complete tumor removal was achieved in 14 patients and near total removal in 5. There was no mortality and in those patients who did not require orbital exenteration excellent to good cosmetic results were achieved in all but one case. This approach affords a wide exposure of the orbit and anterior and middle skull base, so that large tumors of the orbit and tumors involving the orbital apex, sphenoid wing, and infratemporal and pterygopalatine fossae can be removed.
