Abstract

Anatomic variations of the petrosphenoid ligament, Dorello’s canal and the course of the abducens nerve have been extensively described over the past years. In the present report of a single cadaver dissection, we describe an unusual course of the abducens nerve at the level of the petrous bone. The right abducens nerve did not enter Dorello’s canal, but ran below the petrous bone through a narrow canal in the petrobasilar suture, which we called the “petrobasilar canal”. No anatomic variations of the left abducens nerve were noted.
