15 March 2016 â¢ 2:25pm. The death of an American tourist in a horrific lion attack in South Africa in the summer of 2015 was a stark reminder of the dangers that can be posed by wildlife.

Some of the middle ear structures may be seen through an especially transparent ear drum, while the inner ear may be evaluated only by CT scans, MRI scans or indirectly by special testing, such as audiometry (hearing tests) or other special tests of inner ear function.
The following page is intended to help clarify what is meant by the widely used description of fluid in the ears with regard to middle ear disease. This figure shows a schematic of a section through the head, showing the main components of the ear. The ear canal, as far down as the ear drum, makes up the outer ear. The middle ear is the cavity behind the ear drum which contains the middle ear bones. The inner ear includes the blue coiled structure, the cochlea, which is the subject of our research. This figure shows a more schematized version of the above illustration. The color white indicates the air-filled spaces.
