Eight Items to Check on a Temporal Bone CT-Scan

Imaging data provided by computed tomography scans of the temporal bone are fundamental for both the diagnosis and treatment of diseases affecting this complex structure. Despite its importance, the expertise required to analyze this exam is seldom properly acquired as it is time-consuming and often neglected among young doctors and even otolaryngologists. Physicians may not even have a look at the scans but rely only on radiology reports. Radiologists, on the other hand, may not describe the individual scans the same way as clinicians. Lack of a standardized and didactic protocol for scrolling through the images obtained might also contribute to the difficulties reported by residents and physicians in daily practice. We present here a sequential checklist which could be employed in a systematic and organized manner, aiming to both develop and practice the know-how of this indispensable and challenging method of evaluation of the temporal bone.
