The ear is made up of three parts. The outer ear includes the part you can see and the canal that leads to the eardrum. The middle ear is separated from the outer ear by the eardrum and contains tiny bones that amplify sound. The inner ear is where sounds are translated to electrical impulses and sent to the brain
The symptoms of an ear infection depend on the type, but may include:
- mild deafness or the sensation that sound is muffled
- ear discharge
- loss of appetite
- itchiness of the outer ear
- blisters on the outer ear or along the ear canal
- noises in the ear – such as buzzing or humming
- vertigo (loss of balance).
Too much moisture in the ear can irritate and break down the skin in the canal, letting bacteria or fungi penetrate. It happens most often in summertime, when swimming is common.
Infection of the bone that can be felt immediately behind the ear is called the mastoiditis.
Middle ear infection (otitis media). A middle ear infection often results in the accumulation of fluids in your middle ear. Pressure from these fluids can cause the eardrum to rupture. A ruptured eardrum also called tympanic membrane perforation as it's medically known is a hole or tear in the thin tissue that separates your ear canal from your middle ear
A middle ear infection, is one of the most common conditions among children. They shouldn’t be ignored. Untreated ear infections can lead to unnecessary pain and permanent hearing loss for your child. An ear infection occurs in the middle ear and is caused by a bacterial or viral infection.
Serous otitis media is known as glue ear. Children aged between six months and two years of age are most vulnerable to this type of ear infection. Glue ear commonly develops after a middle ear infection, and is characterised by the build-up of fluid and pus within the middle ear.
Infectious myringitis is inflammation of the eardrum, caused by infection from either viruses or bacteria. The eardrum responds to the inflammation by forming small blisters. This can be quite painful.
is inflammation of the vestibular nerve which characterized by a sudden severe attack of vertigo (a false sensation of moving or spinning). May be accompanied by nausea and vomiting.
