[Usefulness of fronto-orbito-zygomatic approach for intraorbital tumors: report of 31 cases].
We have encountered 31 cases of intraorbital tumors at the Kobe University Hospital between 1971 and 1996. We reviewed those cases taking into account the surgical approaches used, the removability of the tumors and functional outcome. Before 1991, frontal or fronto-temporal craniotomy had been mostly used whereas the fronto-orbito-zygomatic approach or fronto-orbital approach has been used only since 1992. After introduction of these approaches, functional outcome was significantly improved. Most of the tumors have been successfully removed totally. In particular, this approach is thought to be useful for tumors located in the deep portion of the orbit and for tumors extending intracranially. In addition, removal of the anterior clinoid process and the opening of the optic canal as well as the superior orbital fissure provides a wider operative view and enables the transposition of the optic nerve safely.
