Otitis media is an ear infection of the middle ear that causes pain, fever and hearing loss
Otitis media is one of the commonest ear problems in children – by the age of five, nearly every child has experienced at least one episode of otitis media, so otitis media is one the commonest children’s ear problems
Most ear infections either resolve on their own (viral) or are effectively treated by antibiotics (bacterial)
Fluid in the middle ear may remain for months after the infection resolves
Ear infections and/or fluid in the middle ear may become a chronic problem leading to other issues such as hearing loss, behavior, and speech problems
Recurrent otitis media
Situations where middle-ear infections are likely to recur:
Children prone to upper respiratory infections
When fluid in the middle ear is present from previous infections
Children’s day care
Where the Eustachian tube does not function
Chronic otitis media (Glue ear)
Otitis media with middle ear fluid that has been present for three months or more is called glue ear
The middle ear fluid is often thick like glue
Risk factors for glue ear include:
Poor Eustachian tube function
Children under the age of three
A recent ear infection
Colder weather
Other children’s problems such as cleft palate
The Eustachian tube
The Eustachian tube connects the middle ear to the throat
Its purpose is to equalize middle ear pressure
When the ear “pops” the reason is that the Eustachian tube has opened and equalized pressure
If the Eustachian tube does not function properly then middle ear fluid cannot drain and fluid in the middle ear interferes with hearing
Children tend to grow out of otitis media and glue ear with development of the Eustachian tube and accordingly, children older than seven or eight years are less prone to middle ear problems
Complications of persistent glue ear
Glue ear can cause the ear drum to thin and fall in – called a retraction pocket
This can lead to further complications and hearing loss
If the ear drum is severely retracted chronic middle ear disease and cholesteatoma may develop
A cholesteatoma is an abnormal growth of skin misplaced in the middle ear
Who needs ear grommets?
Grommets are often recommended when a person experiences repeated middle ear infection (acute otitis media) or has hearing loss caused by the persistent presence of middle ear fluid (otitis media with effusion)
These conditions most commonly occur in children, but can also be present in teens and adults and can lead to speech and balance problems, hearing loss, or changes in the structure of the ear drum
Other less common conditions that may warrant the placement of grommets are malformation of the ear drum or Eustachian tube, Down Syndrome, cleft palate, and barotrauma (injury to the middle ear caused by a sudden change in air pressure), usually seen with altitude changes such as flying and scuba diving
In children, where there are problems associated with glue ear and hearing loss including delay in speech development, learning difficulties, behavioural problems, frequent ear aches or balance
Childrens ear grommets
Ear grommet placement aims to:
Treat children’s ear problems and restore hearing loss caused by middle ear fluid
Improve speech problems and balance problems
Improve behavior and sleep problems caused by chronic ear infections
Reduce the risk of future ear infection
Treat ear drum retraction and chronic middle ear disease
