title: Petrous apex cholesterol granuloma treated via the endoscopic transsphenoidal approach.

They are usually treated via the transtemporal- or middle fossa approach; some are managed endoscopically. We present a patient treated by the endoscopic transsphenoidal approach and review the literature.
