Facial nerve (FN) is the seventh cranial nerve with a unique complex anatomical course. Knowledge about the normal predictable course within the temporal bone with its possible variations is crucial to avoid accidental injuries to the FN, preventing its devastating subsequences. In ear surgeries, certain landmarks and relations to each other are key for safe drilling. In this report, we describe a case with computed tomography findings during routine preoperative assessment for cochlear implant with anomalous FN course being displaced posterolaterally on the tympanic and mastoid segments. This highlights the importance of imagining before such surgeries.
