Hearing loss is considered a problem of conduction when the outer ear, eardrum, or middle ear restricts sound from being processed.
There are many potential causes of conductive hearing loss, with some problems being easier to treat than others.

The outer ear consists of the auricle (unlabelled), the external auditory canal, and the lateral surface of the tympanic membrane (TM).
There are several other audiological tests that are also commonly abnormal in persons with conductive hearing loss. Tympanometry usually is either flat (as shown below), or shows an abnormally large volume (indicating a perforation). Other tests that may be helpful in confirming conductive hearing loss are OAE testing and temporal bone CT scan. Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, typanosclerosis (as shown above), superior canal dehiscence (which can also cause a conductive hyperacusis), external or middle ear infections (otitis externa or media), allergy with serous otitis media (fluid in middle ear), trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear such as a glomus tumor, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane. A hole in the ear drum, which is called a tympanic membrane perforation, causes a conductive hearing loss. It is generally attributed to previous ear infections or trauma (such as a tube insertion). The last step in the chain of signal transmission between sound in the air and movement of fluid in the inner ear is the middle ear. There are three small bones interposed between the large ear drum, and the small hole (oval window) across which sound is transmitted into the inner ear.
Complete ossicular chain discontinuity usuall results in a large, flat conductive hearing loss. Characteristically, hearing aids work well for conductive hearing loss, and very good hearing results can be obtained.
Surgical treatment is also generally available for conductive hearing loss as it is always due to a mechanical problem.
Most surgical treatments for otosclerosis or middle ear disease involve opening of the middle ear and repair under direct vision. However, in our opinion (which is not representative of general opinion of ear surgeons), we think it is preferable to use a hearing aid until hearing becomes unservicable, and then move onto an implanted hearing aid, and skip the middle ear surgery part altogether.
Sensorineural hearing loss is the most common type of hearing loss, occurring in 23% of population older than 65 years of age. Infections, such as meningitis, are a common cause of hearing loss in children where it occurs in approximately 20% of those with streptococcus pneumoniae meningitis (Heckenberg et al 2011). Noise induced hearing loss is a permanent hearing impairment resulting from prolonged exposure to high levels of noise. Children who are born prematurely or contract certain infections in utero are at a higher risk of hearing loss (Hille et al 2007, Roizen 2003).
While very unusual, acoustic neuromas or metastatic cancer (particularly breast) can be a source of hearing loss. Sudden hearing loss (SHL) is defined as greater than 30 dB hearing reduction, over at least three contiguous frequencies, occurring over 72 hours or less. Sensory presbyacusis is caused by loss of sensory elements in the basal (high-frequency) end of the cochlea with preservation of neurons. Cochlear conductive presbyacusis is caused by thickening of the basilar membrane caused by deposition of basophilic substance.
Because presbycusis occurs in some individuals as they age but not in others, genetic or environmental factors must also play a role in its development (Liu & Yan 2007).


In conductive hearing loss, the second most common form of hearing loss, sound is not transmitted into the inner ear.
Images marked as copyright Northwestern University were developed with the support of a National Institutes of Health (NIH) grant to Northwestern University Dept. The American Hearing Research Foundation is a non-profit foundation that funds research into hearing loss and balance disorders related to the inner ear and is also committed to educating the public about these health issues. The new MED-EL Sports Headband provides comfort and security for sports and many other physical activities. TriformanceExperience the fullest, richest range of sounds and perceive speech and music more naturally. RehabilitationCochlear implant users of all ages can practice speaking and listening skills with interactive and downloadable (re)habilitation activities.
Any problem in the outer or middle ear that prevents sound from being conducted properly is known as a conductive hearing loss.
Sensorineural hearing loss results from missing or damaged sensory cells (hair cells) in the cochlea and is usually permanent. Mild to severe sensorineural hearing loss can often be helped with hearing aids or a middle ear implant. A problem that results from the absence of or damage to the auditory nerve can cause a neural hearing loss. Hearing aids and cochlear implants cannot help because the nerve is not able to pass on sound information to the brain. This type of hearing loss is not noise-induced (though the ear may also suffer from some noise-induced hearing loss), and it is often reversible either medically or surgically if there is no damage to hair cells in the ear.
This type of hearing loss may be indicative of something more serious, such as a tumor on the hearing nerve, or something relatively easy to remedy, such as an earwax blockage in the ear canal.
Antibiotics or antifungal medications are usually prescribed for ear infections, whereas surgery is usually an option for malformed or abnormal outer or middle ear structures and other physical problems. The middle ear includes the medial surface of the eardrum, the ossicular chain of bones, the eustachian tube.
These can be immensely troublesome because their removal can be difficult, and infections are common.
It is more accurate to say that there is a hearing reduction, as generally hearing is not greatly affected -- a 10 db drop is typical. There also seems to be a weak association with increased serum calcium (de Carvalho et al, 2006) .
When these bones are fused (otosclerosis, or ossicular fixation) or broken (ossicular chain discontinuity), a conductive hearing loss is the inevitable result. When combined with a sensorineural hearing loss, this pattern may look superficially like a conductive hearing loss, because there is an air-bone gap. Persons with LVAS may develop hearing loss as well as be unusually vulnerable to inner ear disease associated with head injury. Recently some groups (Kakehata et al, 2006) are using endoscopy for repair of ossicular chain disturbances -- in our opinion, this is still very investigational and somewhat unreasonable -- when working inside a tiny space, one needs as good an exposure as one can manage.

The outer ear includes the auricle, the external auditory canal, and the lateral surface of the tympanic membrane (TM).
Postmeningitic hearing loss can be due to lesions of the cochlea, brainstem and higher auditory pathways, but usually is related to suppurative labyrinthitis (cochlear damage). One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech.
Much research has focused on the detection of genetic causes of hearing loss, and many of them can now be diagnosed at an early age (Blanchard et al 2012, Dror & Avraham 2009, Kochhar et al 2007, Kokotas et al 2007, Robin et al 2005, Xing et al 2007).


Risk factors that correlate with hearing loss in premature infants include hypoxia, mechanical ventilation, hyperbilirubinemia, very low birth weight, and the use of ototoxic medications. It occurs most frequently in the 30- to 60-year age group and affects males and females equally. These patients have symmetrical, high-frequency sensorineural hearing loss (as shown in Figure 3). Medical conditions that are common in the elderly, such as diabetes and stroke, may also increase the risk of hearing loss with aging (Bainbridge et al 2010, Helzner et al 2005, Maia & Campos 2005, Schreiber et al 2010). Causes include a buildup of ear wax, a foreign body in the ear canal, otosclerosis, tympanosclerosis (as shown in Figure 4), external or middle ear infections (otitis externa or media), allergy with serous otitis media, trauma to the ossicular chain such as temporal bone fracture, tumors of the middle ear, erosion of the ossicular chain (cholesteatoma) and perforation of the tympanic membrane.
Malformation of the outer or middle ear structures, a middle ear infection in which fluid accumulates behind the eardrum, abnormal bone growth in the middle ear, a hole in the eardrum, or poor Eustachian tube function may be responsible for conductive hearing loss.
Hearing aids are often the best answer when surgery is not possible, because they significantly improve hearing and are convenient. These are most easily removed using an examining microscope, but in some instances, surgical removal is needed.
It is presently thought that persons taking calcium supplements are not at increased risk, and also that there is no risk from calcium channel blocker medications. The most common ones are cholesteatoma associated with chronic ear infection (it is not a true tumor) and glomus tumors.
The middle ear includes the medial surface of the TM, the ossicular chain, the eustachian tube, and the tympanic segment of the facial nerve.
These conditions are relatively common in premature infants, and the majority do not go on to develop hearing deficits.
Hearing loss in adults surviving pneumococcal meningitis is associated with otitis and pneumococcal serotype. Race and sex differences in age-related hearing loss: the Health, Aging and Body Composition Study. This process ensures that without your approval, data will not be transferred to the social networks. Though usually not necessary, cochlear implants that directly stimulate the cochlear nerves are another option. Practically, this is a very uncommon situation, of much more interest to diagnosticians than patients.
The inner ear includes the auditory-vestibular nerve, the cochlea and the vestibular system (semicircular canals).
The National Institute of Health reports that about 15 percent of Americans aged 20 to 69 have high frequency hearing loss related to occupational or leisure activities. If the loss is minor, then avoidance of noise and ototoxic medications may be an appropriate treatment.
Trauma is more likely to affect hearing in patients who suffer a temporal bone fracture or are older in age (Bergemalm, 2003). Because of occupational risk of noise induced hearing loss, there are government standards regulating allowable noise exposure.
People working before the mid 1960s may have been exposed to higher levels of noise where there were no laws mandating use of devices to protect hearing.
Occasionally, persons with acquired deafness can be treated surgically with a surgically implanted device, a cochlear implant.
