Computed Tomography Evaluation of the Correspondence Between the Arcuate Eminence and the Superior Semicircular Canal.

Background: The arcuate eminence (AE) has been traditionally used in middle cranial fossa (MCF) surgery as a guide to accurate location of the superior semicircular canal (SSC) deep within the temporal bone. However, the anatomic relationship between the AE and SSC is controversial. We evaluated the anatomic coincidence between the AE and the SSC in the MCF surface.
