Multiplanar Reformatted Imaging of the Temporal Bone

Multiplanar reformatted imaging is a useful technique in cross-sectional imaging. Multiplanar reformatted imaging allows for the creation of images in planes that are oblique to the original volumetric data. Use of this tool is particularly important in the temporal bone, an anatomically complex structure that is composed of minute osseous landmarks, foramina, clefts, and aqueducts. For example, multiplanar reformatted imaging can be used to assess the integrity and alignment of the ossicles, highlight various pathologic entities, and evaluate the morphology of the inner ear structures. This video article discusses the use of multiplanar reformatted imaging in temporal bone imaging, focusing on its use in the assessment of normal anatomy and postoperative changes.
