Glue ear is a term to describe the build up of fluid/mucus (essentially snot) in the middle ear space.
The condition is very common in children from the ages of 2 to 5 and occurs mostly in the winter.
An ear infection or a cold may precipitate the development of glue ear and in most children the glue ear resolves within a few weeks after onset.It may cause a and cause a hearing impairment and in some children it may persist. Occasionally it can cause children to become off balance and clumsy. Generally if it is present for more than 3 to 4 months it is likely to persist particularly in the winter season.
