About Microscopic Clearance Of The Ear

The external ear is a narrow canal that ends at the eardrum. In order to have pinpoint accuracy in removing material from the ear canal, ENT surgeons use an operating microscope that allows binocular visualisation so that procedures can be performed with very fine instruments. This is known as microscopic clearance of the ear.

Some examples include: foreign bodies, obstructing ear wax, keratosis, pus and debris related to infections of the ear. Ear wax that is not completely obstructing may nevertheless obscure the view of the eardrum and middle ear; these need to be cleared for proper examination or in preparation for hearing tests.
