The aim is to study the anatomical morphology of the arcuate eminence and its relationship with the superior semicircular canal by radiological study and subsequent anatomical dissection, after milling, and to assess the correlation between the two structures. There are others in which the arcuate eminence is caused by pneumatization processes of the epitympanic region. However, there are studies in which this eminence does not coincide exactly with the superior osseous semi-circular canal, but adapts to the occipitotemporal sulcus on the inferior surface of the temporal lobe of the cerebral hemisphere. It is used in surgery of the middle cranial fossa as a reference point to locate the internal acoustic canal within the temporal bone. In the more classical treatises on human anatomy, the arcuate eminence is defined as the elevation produced by the prominence of the superior semi-circular canal on the anterior surface of the temporal bone, at the junction of the posterior third with the anterior two thirds, whereby it is related to the middle cranial fossa, and separated from it by the meninges.
