Abstract

MOST dogs and cats with common aural conditions, such as otitis externa or aural haematoma, may be treated satisfactorily without the need for diagnostic imaging. However, animals with recurrent or severe otitis, and those with more marked signs, such as para‐aural swelling, pain on opening the mouth, vestibular syndrome or facial paralysis, may benefit from a more thorough work‐up to examine the middle ear and adjacent structures. In such cases, the anatomical complexity and relative inaccessibility of these structures is best addressed by diagnostic imaging ‐ involving, as appropriate, radiography, computed tomography, magnetic resonance imaging or ultrasonography. This article reviews the use of these imaging techniques in dogs and cats with clinical signs of ear disease and illustrates some of the more typical findings.
