Glue ear
When middle ear infection occurs, the lining of the middle ear secretes fluid. This is thin at first but may become thick, like glue, if the middle ear stays inflamed and the air cannot get in. If the thick fluid does not go away this is called glue ear. Your child hears poorly through this thick fluid and may seem deaf (and need the TV up louder) or seem inattentive or off-balance or irritable.
