Superolateral orbital exposure and reconstruction.

Based upon experience with 10 cases of surgical excision of orbital tumors, we describe a modification of the supraorbital and lateral approaches to the orbit. This technique gives a wide superior and lateral exposure of the orbital contents for microsurgical removal of orbital tumors. It is particularly applicable to large orbital neoplasms, tumors in the orbital apex, growths with intracranial extension, and medial orbital tumors. Two separate bone flaps are removed: a craniotomy (or cranio-orbital) flap that includes the superior and lateral orbital rim and a smaller, more posterior flap that includes the remainder of the roof and lateral wall of the orbit. After excision of a tumor, the orbital walls can be reconstructed in their entirety or the surgeon can leave out the smaller, posterior flap for orbital decompression. After reconstruction there are no significant anatomic, functional, or cosmetic deficits.
