Abstract

Throughout this chapter examples of imaging studies will be shown. These examples not intended to form a comprehensive atlas of imaging pathology, but to demonstrate various techniques of imaging of particular value to the otolaryngologist. The role of imaging in otology/neurotology is to know nature of the disease, structure involved, disease extent and required surgical approach. In general terms, computed tomography (CT) is superior for bone imaging of the bony anatomy, bone erosion, and bone destruction. Magnetic resonance imaging’s sharp contrast differentiation of different soft tissues makes it the investigation of choice for demonstration of the dura, the brain, cerebrospinal fluid (CSF), skeletal muscle, and tumors. Other imaging techniques less commonly utilized include the use of plain films, nuclear medicine (radionuclide imaging), and digital subtraction angiography (DSA).
