Conductive Hearing Loss is caused by anything that interferes with the transmission of sound from the outer to the inner ear.
Other conditions such as diabetes, untreated high blood pressure, thyroid problems and many more.

If you have recently discovered that your child has hearing loss, it’s important to get the facts about what lies ahead as soon as possible. Quick and effective intervention is usually the basis of successful treatment, but different causes of hearing loss require very different care plans. Thankfully, there are many options available for children with partial hearing loss, and some of them have the potential to completely reverse the initial symptoms. Your child may have been diagnosed with hearing difficulties, but the first step towards devising a specific care plan involves finding out the cause of the condition. Comprehensive hearing tests for children will be required to get to the root cause of your child’s problem. For instance, automated otoacoustic emissions tests (AOAE) involve a series of clicking noises. Your child may also have to undergo an automated auditory brain-stem response test, which involves sensors being place on the head and neck in order to pick up nerve responses when a sounds is played through a set of headphones. Your child will be asked to press a button or respond in an age appropriate way when each sound is heard.
Your child’s consultant or audiologist will talk you through the options available once a root cause for the hearing loss has been ascertained. If your child has irreversible hearing loss, but has some residual hearing, technology might be recommended.
You might also be given advice on the various technological aids that can improve your child’s quality of life. If your child’s hearing can be improved, there are some medications and surgical procedures that could help. In most cases, these infections can be treated with nothing more than antibiotics and careful monitoring.
Some babies are born with structural defects in their middle or outer ear, which can lead to hearing problems.
Unfortunately, some cases of hearing loss are total, in which case your child might be referred to a sign language tutor. After an initial diagnosis of hearing loss, your child will undergo a series of more detailed tests to get to the root cause of the issue.
However, with the right support, an early diagnosis and a team of experienced physicians, nurses and audiologists, your child stands a great chance of living a normal and productive life.

There are two general types of hearing loss: Conductive hearing loss and Sensorineural hearing loss. Conductive hearing loss is caused by any disruption in the passage of sound from the external ear via the middle ear to the oval window.  Possible causes are impacted wax,  tympanic membrane perforation, otitis media, middle ear effusion, ossicle problems including otosclerosis.
The decrease in auditory acuity seen in conductive hearing loss is caused by pathology of either the outer or middle ear. In these cases, hearing loss is caused by a mechanical occlusion of the external auditory meatus. What is a 'normal' tympanic membrane?A normal tympanic membrane is thin and transparent, allowing visualisation of the air in the tympanic cavity.
There are two primary categories of hearing loss in children: congenital (present at birth) and acquired (occurring after birth). Some children have sensorineural hearing loss (also called nerve deafness), which is permanent.


Parents of all babies born at CUMH will be offered a hearing screening test for their baby prior to being discharged from hospital.
For babies, there is the ‘Infant Distraction Test (IDT) screen' (a behavioural test of hearing, based upon the child's ability to turn to a sound) usually performed by public health nurses on babies at around eight months of age.
At school entry, there is a hearing screening test based upon the pure tone audiometry ‘sweep' test performed by public health nurses.
It is important to observe your child for any signs of potential hearing loss.Does your child:Turn up the volume of the TV excessively loud?Respond inappropriately to questions? While these signs don't necessarily mean that your child has a hearing problem, they could be indicators of one. If the hearing loss is temporary, your audiologist or ENT surgeon will advise you on the best course of action, which may involve antibiotics or minor surgery. It may be helpful to write down questions as you think of them, and take them with you to this appointment. If your child has been diagnosed with some degree of permanent hearing loss, he or she should now be seen by the ENT (ear, nose and throat) Department on a regular basis to maintain his or her hearing aid and for regular hearing tests.
The Visiting Teacher Service is provided by the Department of Education & Science from the time of referral through to third level education. The nature and frequency of visits will depend on a range of factors, including the age of the child, severity of hearing loss, educational placement and individual learning needs. The Visiting Teacher calls to your home and supports the family, provides information about hearing loss and advises on the management of amplification devices (hearing aids, cochlear implants, FM systems, etc.) and the satisfactory development of communication skills. The involvement of the Visiting Teacher continues throughout the education of a child with a hearing loss.

These can be divided into two basic types, called conductive and sensorineural hearing loss. Exposure to certain diseases in utero or soon after birth can harm the hearing mechanism of a baby. There are several reasons for hearing loss in children, and discovering which of them led to your child’s problems is the key to successful treatment. Sometimes, three or four different tests are needed before a definitive diagnosis can be made. If your child is old enough to communicate responses, a pure tone audiometry test could be given, which involves a series of sounds being played at varying volumes and frequencies.
There is also a chance that a bone conduction test will be ordered – involving a bone ‘vibrator’ being placed behind the ear to test how well the hearing nerve is performing. For instance, a hearing aid amplifies sounds, and cochlear implants send sound signals directly to the hearing nerve. An FM system might be added to a hearing aid in order to help your child pick up conversations when there is significant background noise.
This is particularly the case if your child is suffering from conductive hearing loss, or if there is a problem with the middle or outer ear. Certain infections can lead to a build-up of fluid in the middle ear, which can block sounds from passing.
In a small number of cases, however, the fluid build-up will need to be surgically removed, which will involve placing a tiny tube into the eardrum after the fluid has been drained away.
If this happens, you and other members of your family will need to attend lessons as well, so you can include your child in daily family life.

The most common pathologies are covered in this chapter, but this list is in no means exhaustive. Acquired hearing loss (generally appears in adults), but has an dominant autosomal genetic component with a variable penetration.


If they have a hearing loss that is undetected and untreated, they can miss much of the speech and language around them. About four in every 1,000 children at school entry level in Ireland have unilateral (in one ear) and bilateral (in both ears) mild to profound hearing loss. Most of these children have some usable hearing, and children as young as three months of age can be fitted with hearing aids. However, the first phase of a National Newborn Hearing Screening Programme was launched in Cork University Maternity Hospital (CUMH) in April 2011.
During this test, the child will listen to a range of beeps and whistles (called pure tones) and indicate when they can hear them, by pressing a button. It is important to recognise the signs of hearing loss in infants and toddlers as early as possible. If you answered "yes" to any of the above questions, or if you suspect your child may have difficulty hearing, arrange an appointment with your GP who will investigate further and refer you to an audiologist (hearing expert) or ENT (Ear Nose and Throat) consultant, if necessary. If your child has been diagnosed with permanent hearing loss, it is sometimes difficult to take in everything the specialist is saying to you. Furthermore, when your child is identified with a hearing loss, the audiologist should make a referral to your local Education Department to arrange for a visiting teacher for children with hearing loss to visit you in your home. Each Visiting Teacher is responsible for a particular region and is allocated a caseload of pupils. At present, the majority of children with a hearing loss are enrolled in the mainstream school system.
Acquired hearing loss happens at a later stage and can be due to factors such as disease, noise or trauma to the head. A bone-anchored device might be recommended if your child is unable to wear a hearing aid that fits either in or behind the ear. Captioning options are available on all modern televisions, and a range of visual aids are available for devices (such as phones) which rely on auditory signalling. Particular attention should be paid to piercings in the cartilage as these are a main contributor to chondritis (see picture). The malleus is less visible and its handle causes a depression at its join with the tympanic membrane. That means between 3,000 to 4,500 preschool and school age children in Ireland will have a permanent hearing impairment, with potential consequences for communication, literacy, social and emotional development, and later employability. Many children with temporary hearing loss can have their hearing restored through medical treatment or minor surgery. This screening service is gradually being expanded across HSE South and throughout the country. Any baby who does not have a clear response in one or both ears from the test will be seen for a full audiological (hearing) assessment at an Audiology Clinic in Cork University Hospital (CUH) shortly after discharge.
The most critical period for speech and language development is from birth to four years of age.
At this level, the Visiting Teacher continues to visit the children at home and at school, providing advice and guidance on the education of the child. In fact this case isn't a real perforation as the eardrum is still intact, it has just been sucked in towards the bottom of the tympanic cavity.Cholesteatoma is characterised by an accumulation of squamal cells in the retracted region.
The second appointment is a good time to ask any questions you may have as you would have had time to think about the situation. In addition, the Visiting Teacher discusses with parents the range of educational options available and makes recommendations regarding appropriate placement. A break in the ossicular chain is classic, and it can sometimes affect the inner ear, which is reflected in a mixed hearing loss (reduction in air and bone conduction).
