small tears and stenosis may block the flow.
CT is very quick, and highly sensitive and specific for stenosis and occlusion of the ear canals, and bulging or rupture of the tympanic membrane. The ear canals should be thin-walled, open and gently taper to the tympanic membrane. The middle ears should be thin- walled and air filled. The density of the material in the ears can differentiate debris from stenosis, and contrast enhancement can be used to identify inflamed soft- tissues. Mineralisation of the ear canals is easily seen. MRI is less good for imaging the ear canals but can
be useful for imaging soft-tissue structures such as neoplasia, infection and nerves in or around the ears.
Myringotomy
Myringotomy should be considered if the eardrum bulges into the ear canal, is opaque or otherwise abnormal, and/ or there is evidence of otitis media. This is best done
with a video otoscope, which allows precise puncture in the caudal-ventral pars tensa using a cut catheter, ENT swab or spinal needle. This allows access to the middle ear to see the contents, collect samples for cytology and culture, to flush out debris, and instil medication.
