A cholesteatoma is a skin growth that occurs in an abnormal location, the middle ear behind the eardrum. Cholesteatoma is a serious but treatable ear condition which can only be diagnosed by medical examination.
Otitis media is the inflammation of the middle ear and occurs most commonly during the winter and early spring months.
Remember, without proper treatment, damage from an ear infection can cause chronic or permanent hearing loss. Earwax is healthy in normal amounts and serves to coat the skin of the ear canal where it acts as a temporary water repellent.
Most of the time the ear canals are self-cleaning; that is, there is a slow and orderly migration of ear canal skin from the eardrum to the ear opening.
When cerumen is removed from the ear, the physician uses sucion, a cerumen spoon, or delicate forceps to do so.
A perforated eardrum is a hole or rupture in the eardrum, a thin membrane that separates the ear canal and the middle ear.
Middle ear infections may cause pain, hearing loss, and spontaneous rupture (tear) of the ear-drum resulting in a perforation. On rare occasions a small hole may remain in the eardrum after a previously placed PE tube (pressure equalizing) either falls out or is removed by the physician.
Most eardrum perforations heal spontaneously within weeks after rupture, although some may take up to several months. The most common symptoms of swimmer’s ear are mild to moderate pain that is aggravated by tugging on the auricle and an itchy ear. WARNING: If you already have an ear infection, or if you have ever had a perforated or otherwise injured eardrum, or ear surgery, you should consult an ear, nose, and throat specialist before you go swimming and before you use any type of ear drops. The tympanogram is a test that measures how easily the eardrum vibrates back and forth and and what pressure the vibration is the easiest.
The ABR is a special hearing test that can be used to track the nerve signals arising in the inner ear as they travel through the hearing nerve (called the auditory nerve) to the region of the brain responsible for hearing. The ABR can also be used on small infants since it requires no conscious response from the person being tested. The ENG (short for electronystagmogram) is actually not a hearing test but rather a special test of the balance mechanism of the inner ear. If ear infections go untreated the infection (similar to pus) in the middle ear space can grow and grow until it bursts the eardrum, resulting in a draining ear.
Cholesteatoma and ear tubes: When a child has had tubes inserted, a small cut is made in the eardrum for the tube to fit into. Cholesteatoma prevention: The secondary effects of ear infection, including infection spreading into the mastoid (the bump behind your ear) and the development of cholesteatoma was once a leading cause of death in children. How our ears work: In order to understand what a conductive hearing loss is, it is important to know a little about how we hear. Experience a bit of hearing loss: Plug your ears with your index fingers to experience a conductive hearing loss.
You understand better if you can watch people as they speak, but this is hard as people turn their heads, move around, cover their faces with their hands, etc. A child experiencing frequent ear infections will have hearing loss that can change from day to day. My thanks to Judith Blumsack, PhD, who collaborated with me during the development of this information.  Information in this article is not intended as medical advice. A recent study on cod liver oil and ear infections shows you may reduce the severity and duration of the infection by using this healthy oil. Researchers claim that up to 75% of children will have up to three more ear infections before they turn 4 years old. This procedure is only temporary and it helps to equalize the pressures in your middle ear.
You can get more detailed information on otitis media at the National Institute on Deafness and Other Communication Disorders website.
New York - A recent study indicates cod liver oil may reduce the duration and amount of antibiotics needed to treat middle ear infection. Researchers at Columbia University discovered children undergoing surgery for inner ear tube placement had below normal levels of selenium, vitamin A and the omega 3 fatty acid, eicosapentaenoic acid (EPA). Doctors asked what would happen if these patients had increased their dietary intake of these nutrients?
Researchers found that children using cod liver oil reduced the number days on antibiotics by 12%. Now that's not a lot, but researchers believe the supplementation of a multivitamin and cod liver oil may reduce an ear infection's duration and the length of time needed to stay on antibiotics; and it may also delay the need to prescribe antibiotics.
While this is only a small scale study, the results are encouraging and more larger scale studies are needed to learn the benefits of using cod liver oil on ear infections. Please consult your health-care provider if you wish to follow up on the information presented. Just as with all other aspects of human biology, there is a broad range of Eustachian tube function in children- some children get lots of ear infections, some get none.
Allergies are common in children, but there is not much evidence to suggest that they are a cause of either ear infections or middle ear fluid. Ear infections are not contagious, but are often associated with upper respiratory tract infections (such as colds). Acute otitis media (middle ear infection) means that the space behind the eardrum - the middle ear - is full of infected fluid (pus).
Any time the ear is filled with fluid (infected or clean), there will be a temporary hearing loss. The poor ventilation of the middle ear by the immature Eustachian tube can cause fluid to accumulate behind the eardrum, as described above.
Ear wax (cerumen) is a normal bodily secretion, which protects the ear canal skin from infections like swimmer's ear. Ear wax rarely causes hearing loss by itself, especially if it has not been packed in with a cotton tipped applicator. In the past, one approach to recurrent ear infections was prophylactic (preventative) antibiotics. For children who have more than 5 or 6 ear infections in a year, many ENT doctors recommend placement of ear tubes (see below) to reduce the need for antibiotics, and prevent the temporary hearing loss and ear pain that goes along with infections. For children who have persistent middle ear fluid for more than a few months, most ENT doctors will recommend ear tubes (see below). It is important to remember that the tube does not "fix" the underlying problem (immature Eustachian tube function and poor ear ventilation). Adenoidectomy adds a small amount of time and risk to the surgery, and like all operations, should not be done unless there is a good reason. In this case, though, the ventilation tube serves to drain the infected fluid out of the ear.
The most common problem after tube placement is persistent drainage of liquid from the ear.
In rare cases, the hole in the eardrum will not close as expected after the tube comes out (persistent perforation). I see my patients with tubes around 3 weeks after surgery, and then every three months until the tubes fall out and the ears are fully healed and healthy. If a child has a draining ear for more than 3-4 days, I ask that he or she be brought into the office for an examination. Once the tube is out and the hole in the eardrum has closed, the child is once again dependant on his or her own natural ear ventilation to prevent ear infections and the accumulation of fluid.
About 10-15% of children will need a second set of tubes, and a smaller number will need a third set. Children who have ear tubes in place and who swim more than a foot or so under water should wear ear plugs.
Deep diving (more than 3-4 feet underwater) should not be done even with ear plugs while pressure equalizing tubes are in place.

The Recommendations for clinical care guidelines on the management of otitis media in Aboriginal and Torres Strait Islander populations are intended for use by health care professionals who work with Aboriginal and Torres Strait Islander populations. The clinical care guidelines were prepared by the Darwin Otitis Guidelines Group in collaboration with the OATSIH Otitis Media Technical Advisory Group and were published by the Office for Aboriginal and Torres Strait Islander Health (OATSIH).
The clinical care guidelines are divided into sections: prevention, diagnosis, prognosis, medical management, audiological management of associated hearing loss, practical considerations in health care delivery, and prioritisation of primary health care services in different settings. Options for viewing content of the guidelines include downloading the complete guidelines, viewing individual sections by clicking on the headings, and accessing pdfs from the bottom of each section.

The original 'Recommendations for Clinical Care Guidelines on the Management of Otitis Media'1 were directly linked to the Systematic Review of Existing Evidence and Primary Care Guidelines on the Management of Otitis Media in Aboriginal and Torres Strait Islander Populations (March 2001).2 This updated version is based on the 2001 Guidelines and relevant research studies published since 2001.
Our intended users are health care professionals who work with Aboriginal and Torres Strait Islander populations. Each recommendation has been explicitly linked to the source of the original relevant evidence (type and level) and any evidence ­based guidelines that have made the same recommendation. Each recommendation has been graded according to the most recent National Health and Medical Research Council (NHMRC) grading system 2010.12 Grade A recommendations are based on several level I or II studies with low risk of bias where all studies show consistent results. Body of evidence provides some support for recommendation but care should be taken in its application.
Otitis Media with Effusion (OME): Presence of fluid behind the eardrum without any acute symptoms. Persistent (Chronic) Otitis Media with Effusion: Presence of fluid in the middle ear for more than 3 months without any symptoms or signs of inflammation. Acute Otitis Media (AOM): General term for both acute otitis media without perforation and acute otitis media with perforation. Acute otitis Media with Perforation (AOMwiP): Discharge of pus through a perforation (hole) in the eardrum within the last 6 weeks.

Visual Reinforcement Audiometry: A technique that enables assessment of hearing sensitivity in young children from around 6 months to 3 years of age.
Hearing Impairment Classification: A categorisation that describes the degree of disability associated with hearing loss in the better ear. Any child with permanent or long term (more than 3 months) bilateral hearing loss greater than 20dB in the better ear should be referred to an audiologist for evaluation of hearing and communication needs.

Audiologist: An allied health practitioner responsible for the diagnosis and non-medical management of hearing loss and related verbal communication difficulties. ENT Surgeon: A medical specialist trained in advanced diagnostic, medical and surgical interventions for pathologies of the ears, nose and throat.
Good Practice Point (GPP): This recommendation has been applied where no reliable evidence exists directly assessing the impact of the recommendation. Family Education: Discuss the normal language development milestones and the importance of going to the health centre if their child develops ear discharge. Family Education: Advise the family about the likely hearing loss (usually around 25d B) and the need to re-examine the child in 3 months' time (see chronic OME below). Family Education: Advise the family about the likely hearing loss (usually around 25dB) and the need to organise a hearing test if chronic ear disease affects both ears. Family Education: Emphasise the need to take medications as prescribed and that treatment may need to continue for a long time. GPP*: Tell all expectant mothers about the importance of prevention, early detection and treatment of OM for prevention of OM associated hearing loss. GPP: Ensure that information about OM and effective communication strategies for people with hearing loss is available throughout the community. To attend the health centre as soon as possible whenever a child develops ear pain or discharge, particularly if the child is young.
Some features of OM (such as ear pain) may be absent, and that regular health centre attendance for ear examinations is recommended. GPP: Encourage mothers to continue breast feeding for at least 6 months to reduce the risk of OM. GPP: The health practitioner should tell families or caregivers that nasal discharge carries germs (viruses and bacteria) which are responsible for OM. Grade A: Give pneumococcal conjugate vaccination during infancy according to local immunisation schedule to reduce AOM, rAOM and the need for surgery. GPP: Health staff should undertake ear examinations when they do regular child health checks. GPP: Monitor for hearing loss in all children younger than 5 years and in older children at high risk of hearing impairment. GPP: Refer for hearing tests if there are parental or teacher concerns about hearing or behaviour or learning. Grade A: Accurate diagnosis of OM requires assessment of the appearance of tympanic membrane (TM) by otoscope (or video otoscope) plus compliance or mobility of the TM by pneumatic otoscopy or tympanometry. GPP: Cleaning pus from the ear canal with correctly prepared tissues spears can be done by anybody. These funnel through the ear opening, down the ear, canal, and strike your eardrum, causing it to vibrate. It is usually due to repeated infection, which causes an ingrowth of the skin of the eardrum. Persisting earache, ear drainage, ear pressure, hearing loss, dizziness, or facial muscle weakness signals the need for evaluation by an otolaryngologist-head and neck surgeon.
Old earwax is constantly being transported from the ear canal to the ear opening where it usually dries, flakes, and falls out. However, if you want to clean your ears, you can wash the external ear with a cloth over a finger, but do not insert anything into the ear canal.
It typically occurs in swimmers, but the since the cause of the infection is water trapped in the ear canal, bathing or showering may also cause this common infection.
If you do not know if you have or ever had a perforated, punctured, ruptured, or otherwise injured eardrum, ask your ear doctor. This graph shows the amount of hearing loss expressed in units called decibels at different sound frequencies (also called Hertz). The middle ear is normally filled with air at a pressure equal to the surrounding atmosphere. A special probe is placed up against the ear canal, like an ear plug, and the equipment automatically makes the measurements. The test is useful because it can tell us where along that path the hearing loss has occurred. The test involves running a cool liquid and then a warm liquid through the ear canal (it is usually done through a small tube so the ear itself remains dry).
Typically, it is a growth in the middle ear,  in just one ear but it is possible for it to affect both ears.
The reason for this developmental abnormality is unknown however it is not believed to run in families (not a genetic disorder). This hole can be very ragged, with uneven edges that make it hard for the eardrum to heal smoothly.
Today’s modern medicine can identify cholesteatoma growths and treat them early thereby preventing the most serious hearing loss and other complications, but it is still necessary for the family or individual to seek treatment. Since the source of the problem in many cases is Eustachian tube dysfunction (ears don’t ‘pop’) in about ? – ? of cases the cholesteatoma comes back and additional surgery is needed. A conductive hearing loss happens when sound cannot successfully get from the air, through the outer and middle ear, to be able to be processed by the inner ear and then recognized by the brain. The picture of the parts of the ear will help you understand the chain of events that happens when we hear sound. There are many problems that can interfere with sound reaching the inner ear and cause a conductive hearing loss.
The hearing loss can range from 15 dB up to 60 dB and typically affects low pitch sounds more than high pitch sounds, although all hearing is likely to be affected.
When you pay more attention, the effort spent listening takes away from ‘instant understanding’ meaning figuring out what was said takes a bit more effort too, along with the effort to listen.
Those who have active ear infection along with a cholesteatoma are likely to have some conductive hearing loss that is always there and more hearing loss that fluctuates as their ear problems get better or worse over time.
A special teacher can make sure the classroom teacher understands how unilateral hearing loss affects classroom understanding and can identify the need for a classroom listening device, like a classroom amplification system or a personal FM system.  Your child will benefit from understanding the types of situations that are most challenging and hearing tactics or self-advocacy strategies he can use to ensure that he is able to get the same access to teacher instruction and peer communication as his classmates. For example, some information may be considered appropriate for viewing only by men or only by women.
They are designed to facilitate the delivery of comprehensive, effective and appropriate ear health programs.
It results from a synthesis of information derived from a process of explicit searching of the medical literature and critical appraisal.
This includes Aboriginal Health Workers, Aboriginal ear health workers, primary care and specialist physicians, nurses, remote area nurses and nurse practitioners, audiologists, audiometrists, speech therapists, and child development specialists (including Advisory Visiting Teachers and Teachers of the Deaf). Episodic OME and AOM can cause a mild hearing loss while there is fluid in the middle ear space. This is quite different from the clinical course described in most well-designed studies involving other children (where spontaneous resolution of disease is common).11 This high natural cure rate has meant that intervention studies are limited in their ability to detect sustained clinical improvement over time. Two main information sources of information have been used: i) evidence-based clinical practice guidelines, evidence summaries, and systematic reviews, and ii) high quality primary research on OM and hearing loss.
The criteria used for identifying clinical practice guidelines that have a high likelihood of scientific validity are shown in Table 6. There are likely to be other evidence-based documents in the grey literature that we were not able to identify with our search strategy.
The recommendation (a Good Practice Point) reflects the consensus view of the multidisciplinary guidelines group and is based on clinical experience.
Active inflammation or infection is nearly always associated with a middle ear effusion (fluid in the middle ear space).
Other terms have also been used to describe OME (including 'glue ear', 'serous otitis media' and 'secretory otitis media'). It is defined as the presence of fluid behind the eardrum plus at least one of the following: bulging eardrum, red eardrum, recent discharge of pus, fever, ear pain or irritability.
Definition of CSOM varies in the duration of persistent ear discharge (from 2 weeks to 12 weeks). Other terms have also been used to describe otitis externa (including 'tropical ear' and 'swimmers' ear'). This will apply to most rural and remote Aboriginal communities where persistent disease and chronic perforation of the eardrum are common. This may include the use of symptoms, signs, laboratory tests, or risk scores for the detection of existing or future middle ear disease. It is also called a 'ventilation tube', a 'PE tube' (pressure equalisation tube), or a 'tympanostomy tube'. A perforation in this location may be associated with a deep retraction pocket or cholesteatoma. This may include the use of risk factors, symptoms, signs, electro-acoustic tests or behaviouraI tests for the detection of existing or future hearing loss. This is done using headphones (air conduction) or via bone conductors (bone conduction).Testing is possible from around 3 years of age. Hearing impairment classification applies a graded scale of mild, moderate, severe and profound. Refer to section E for more information about signs, consequences and recommendations of hearing impairment.
This will include consideration of suitability for personal amplification or assistive devices.
Primary health care happens in local communities in a manner acceptable to the local community and with their full participation. Their responsibilities include provision of hearing aids and devices, and auditory training. The recommendation reflects the consensus of the multidisciplinary guidelines group and is based on clinical experience.
If hearing loss is 20-35dB, the child will benefit from classroom sound-field amplification and enhanced communication strategies (e.g. AOMwoP (Acute Otitis Media)Bulging of the eardrum or ear pain plus fluid in the middle ear.
Recurrent AOM3 or more episodes of AOM in the previous 6 months or 4 or more episodes in the last 12 months. If hearing loss is 20 -35dB the child will benefit from classroom sound-field amplification and enhanced communication strategies.
Discuss the normal language development milestones and the importance of presenting early to the health centre if their child develops ear discharge.
Chronic Dry PerforationPerforation without any signs of discharge for greater than 3 months. If hearing loss is 20-35dB, the child will benefit from classroom sound-field amplification and enhanced communication strategies.
If swimming is known to be associated with new or persistent ear infections in an individual, it is reasonable to recommend keeping the ear dry. Assessment tools include simplified parental questionnaires, pneumatic otoscopy and tympanometry (in children older than 4 months). Syringing or cleaning with tissue spears may be required to remove wax, pus or foreign bodies from the ear canal. The vibrations are passed to the small bones of the middle ear, which transmit them to the hearing nerve in the inner ear. Cholesteatomas often take the form of a cyst or pouch that sheds layers of old skin that builds up inside the ear. The middle ear is connected to the nose by the eustachian tube, which equalizes pressure in the middle ear. When water is trapped in the ear canal, bacteria that normally inhabit the skin and ear canal multiply, causing infection and irritation of the ear canal. Simple tests, such as ones done in many schools, may be useful for screening, but a careful audiogram is necessary for accurate diagnosis of most hearing problems. If the middle ear is filled with fluid, the eardrum will not vibrate properly and the tympanogram will be flat.
For example, the ABR is often used for individuals with a sensorineural (nerve) loss in just one ear.


Special electrodes automatically record the nerve signal; the patient can even be asleep during the test. This change in temperature stimulates the inner ear which in turn causes rapid reflex movements of the eyes. This growth can be present behind the eardrum at birth or it can develop later, sometimes as a complication of middle ear infections. Ear infections that can cause conductive hearing loss and ear drainage are very common, especially in young children. Sometimes there are parts of the eardrum tissue that do not heal cleanly and these bits extend into the middle ear space, resulting in the risk for skin tissue to begin to grow in the middle ear, layer upon layer to develop a cholesteatoma. Children who get ear tubes early and  subsequent tubes inserted without delay when needed, are much less likely to develop a cholesteatoma.
It may be necessary, after surgery, for the ear to be cleaned as needed by a health care professional.
For example, if a person has a build-up of earwax in the ear channel that is enough to interfere with the sound reaching the eardrum, that person would have a conductive hearing loss.
Even though you experience a hearing loss, you would likely ‘pass’ a typical hearing screening at a school or doctor’s office. This inconsistency in the ability to hear makes listening extra challenging and can contribute to children learning to ‘tune out’ when there is noise or someone is speaking at a distance.
The HealthInfoNet respects such culturally sensitive issues, but, for technical reasons, it has not been possible to provide materials in a way that prevents access by a person of the other gender. Aboriginal and Torres Strait Islander health staff working with Aboriginal and Torres Strait Islander families are likely to have the greatest impact on severe otitis media. It is best to regard OM as a spectrum of disease that ranges from mild (otitis media with effusion, OME) to severe (chronic suppurative otitis media, CSOM).
Chronic disease (persistent OME and CSOM) can cause moderate hearing loss.8,9 Additionally, the hearing loss can fluctuate depending on the health of the middle ear. For children at high risk of CSOM, we recommend interventions where there is strong evidence of short-term benefit even if the long-term benefits were less clear. While the recommendations have been based on the best available evidence, their applicability will also be dependent on local factors. Grade B recommendations are based on one or two level II studies with low risk of bias or a systematic review of level III studies with low risk of bias. A bulging eardrum, recent discharge of pus, and ear pain are the most reliable indicators of AOM.
Importantly, the diagnosis of CSOM is only appropriate if the tympanic membrane perforation is seen and if it is large enough to allow the discharge to flow out of the middle ear space. The World Health Organization has recommended that rates higher than 4% are unacceptable and represent a massive public health problem. Reduced mobility of an intact eardrum is a good indication of the presence of middle ear fluid.
This type of hearing loss may also occur secondary to dysfunction of any part of the auditory nerve. This is based on degree of deviation from normal thresholds in the 'better ear' as recorded through audiometry. In the first instance, referral would be made to state or territory funded audiological services where available. Primary health care is more than an extension of basic health services and has social and developmental dimensions.
Discuss the normal language development milestones and the importance of going to the health centre if the ear discharge does not improve.
Discuss the normal language development milestones and the importance of going to the health centre if the ear discharge gets worse. Discuss the normal language development milestones and the importance of going to the health centre if the child develops ear discharge. Cleaning with canal instruments can be done by appropriately trained individuals using direct vision (e.g. Here, the vibrations become nerve impulses and go directly to the brain, which interprets the impulses as sound (music, voice, a car horn, etc.).
Over time, the cholesteatoma can increase in size and destroy the surrounding delicate bones of the middle ear. If the middle ear is filled with air but at a higher or lower pressure than the surrounding atmosphere, the tympanogram will be shifted in its position.
This movements are recorded, and from these we can get information about how well this balance mechanism is functioning. When children go to the doctor with draining ears, it is up to the physician to rule out that a rare and serious cholesteatoma is not the cause. When the throat is a bit swollen such as when you get a cold, the Eustachian tube doesn’t open as often as it should. When a person has had multiple burst eardrums the eardrum may end up with weak spots where these holes have healed. At roughly the center of the pinna is a channel (called the ear canal) into which the sound travels on its way to what is called the eardrum (also known as the tympanic membrane). If you hold down the tabs of your ears with your index fingers to close off your ear canals you will have caused a conductive hearing loss. With your ears plugged and your back turned, listen to someone talking from across the room with some noise like the TV on. The guidelines are also suitable to be adopted for use in local clinical practice guidelines and standard treatment protocols (e.g. In all populations, every child will experience episodic OME (fluid behind the tympanic membrane) at some time.5 Nearly all children will experience at least one episode of acute otitis media (AOM). CHL is often regarded as a temporary condition because its causes are generally amenable to medical or surgical treatment.
Most important are the personal preferences of the affected individuals, and the local resources available to assist in the management of OM.
A type B tympanogram or reduced mobility of the eardrum on pneumatic otoscopy are the most reliable indicators of OME. Hearing loss, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth.
If the ABR is normal along that region of the path, the chances of having this tumor are quite small. This tube opens and closes to allow the pressure to equalize between the outside air and the space behind the eardrum. Sometimes a cholesteatoma is right behind the eardrum or has grown through the eardrum and the physician can easily see it. When the Eustachian tube cannot open, the eardrum is pulled inward into the middle ear space as the pressure increases. The eardrum vibrates when sound strikes it, causing a chain of extremely tiny bones (called ossicles) that are located on the other side of the eardrum to vibrate. A person born with a malformed ear in which the entrance to ear canal is closed off (atresia, microtia), would have a conductive hearing loss because the malformation would prevent sound from entering the ear normally.
There are different options for hearing aids for people with conductive hearing loss and your audiologist can help you decide if a regular hearing aid, bone conduction hearing aid, or a bone-anchored hearing device would be most appropriate.
Children are most successful when families are fully involved in advocating for their child’s needs with the school team and supporting his success at home.
In developed countries, most children will improve spontaneously.5 Concerns about OM arise in children who suffer frequent episodic AOM or persistent OME.
These local factors should always be considered when developing an ear health program and when advising families about their management options. Grade B recommendations are applicable to the Australian health care context with few caveats. However, hearing loss associated with OM can vary in severity overtime and have a substantial effect upon hearing for frequencies outside those routinely tested. Suctioning by a trained health care professional may also help to obtain a clear view of the eardrum.
It can also develop in the space in the upper part of the middle ear where the ossicles are, making it impossible to see. A weak spot on the eardrum is likely to retract farther, developing a pouch or sac that can enclose in upon itself and become the start of a cholesteatoma. If the ossicles are malformed or damaged, such as what can happen if there is a cholesteatoma,  they wouldn’t transmit sound well from the middle ear to the inner ear causing a conductive hearing loss.
Children with unilateral hearing loss are at 10 times the risk for problems in school (learning, social, behavior) compared to their classmates without hearing loss. Grade C recommendations are based on Level III studies with low risk of bias or level I or level II studies with moderate risk of bias.
It should be noted that azithromycin is not currently licensed for use in children under six months of age]. The air pressure is changing quickly in this case so your Eustachian tube has to work extra hard to equalize the pressure behind your eardrum.If your Eustachian tube is not working properly, then your ear will start to feel plugged up and it will begin to affect your hearing. If it grows large it can even dissolve through the bone separating the middle ear space and the brain.
In those cases, the only symptom may be increasing hearing loss as the ossicles are dissolved by the cholesteatoma (see conductive hearing loss, below).
The vibration of the last ossicle in the chain causes a small membranous section of the bony inner ear (called the cochlea) to also vibrate.  This vibration causes vibration of fluid that is inside the inner ear, and the vibration stimulates delicate cells inside the cochlea to respond and in turn send a message to the brain that a sound has occurred. This article is specifically about two other causes of a conductive hearing loss: cholesteatoma and chronic middle ear infections. This surprises most people because they assume that if one ear hears normally that there will be no problem. For Grade C recommendations, some inconsistencies reflect genuine uncertainty around the clinical question. It does not account for the impact of early onset, language, processing ability and environmental factors.
If no improvement despite good compliance, consider admission to hospital for IV antibiotic treatment. Serious potential complications of cholesteatoma include hearing loss, brain abscess, dizziness, facial paralysis, meningitis, and spreading of the cyst into the brain. Sometimes this fluid becomes infected by bacteria that have traveled from the throat up the Eustachian tube to the middle ear space. If a problem interferes with the sound vibrations reaching the inner ear, we say that there is a conductive hearing loss.
Grade C recommendations are probably applicable to the Australian health care context with some caveats. Hence, average hearing levels based upon a single assessment could underestimate the degree of impairment.
Once the eardrum returns to a more normal position, even if there is fluid behind it, the earache gets better. Depending on the extent of the problem, a person with a conductive hearing loss might have difficulty hearing only soft sounds or the person have difficulty hearing typical conversation.
