The ear has three parts: the outer, middle and inner ear. The outer ear includes the part outside the head and the ear canal. The eardrum is a small circle of tissue about the size of a fingertip at the end of the ear canal. The middle ear is the space, usually filled by air, behind the eardrum. The inner ear is further inside the head and is important for hearing and balance.
Common ear problems include deafness, tinnitus and vertigo.
Detailed out-patient assessment includes microscopic and photographic evaluation, hearing tests and often MRI scans.
I do not sell hearing aids but can advise on their suitability.
