Conductive Hearing Loss – temporary/ short-term 1. What is glue ear? For ears to work properly the middle ear needs to be kept full of air. The eustachian tube, which usually does this, runs from the middle ear to the back of the throat. In children this tube is not as vertical and wide as it will be when they get older and as a result doesn’t work as well. If the eustachian tube becomes blocked, air cannot enter the middle ear. When this happens, the cells lining the middle ear begin to produce fluid. This can be like a runny liquid which can get thicker as it fills the middle ear. With fluid blocking the middle ear, it becomes harder for sound to pass through to the inner ear. This can make quieter sounds difficult to hear. It can be like listening to the world with both fingers stuck in your ears. It’s hard work, try it for yourself! If your child has glue ear they can’t always hear everything that you say, so it’s no wonder they’re tired and irritable, or just want to be left on their own. 2. Facts about conductive hearing loss and glue ear. Glue Ear may simply clear up particularly if it is associated with a heavy cold. Glue Ear may also fluctuate and can be present one day and not the next. This can lead to permanent conductive hearing problems in later childhood. In Tower Hamlets the incidence of Glue Ear is higher than the national average. Probable causes: damp housing conditions, passive smoking, ear infections, frequent colds. Also the effect of continually sucking on baby bottles by young children causing air locks in the Eustachian tube. The attendance rate at the Audiological clinic and ENT clinic for Tower Hamlets children/pupil’s is also low leading to many children having glue ear or conductive hearing loss being untreated. 3. Educational implications of a conductive hearing loss and glue ear: The teacher needs to be aware that this type of hearing loss fluctuates and so the pupil’s listening ability may vary from day to day. Normal speech will be heard but at a quieter level and therefore when background noise is present the pupil will have difficulty hearing the speaker and may become easily distracted. If English is a second language or the pupil has additional learning needs it is likely to have a more severe effect as it will be more difficult to learn English in poor listening conditions AND with reduced or fluctuating hearing. Due to time spent with reduced hearing and/or the time spent away from school as a result of associated ear infections, children with more persistent or recurrent bouts of glue ear are at risk of social and developmental problems. These include delayed language, difficulties in learning to read, gaps in general knowledge and reasoning ability as well as social and behavioural problems. How past history of a hearing loss can affect present functioning. Full access to language will have been limited in different ways which can result in effect’s on a pupil’s understanding of vocabulary, structures, figurative language, idioms and general concepts. This means that in the best listening conditions a pupil may not understand what s/he is hearing ad assumptions cannot be made about his/her background knowledge. s/he may not have the same conceptual awareness to draw from as his/her hearing peers.
