A conductive hearing loss occurs when there is a problem with the one or more of the parts of the ear that conduct sound into the inner ear. There are many potential causes of conductive hearing loss, with some causes being easier to treat than others.
If you have any questions about conductive hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist.
An audiogram shows the softest sounds a person can hear at different frequencies (pitches). The frequencies displayed on the horizontal axis of the audiogram are those most crucial to hearing and understanding conversation, with low frequencies on the left and higher frequencies on the right.
Information on audiograms is encoded using symbols, each of which represents a different test condition. Audiologists present stimuli via bone and air conduction to determine the type of hearing loss.
When the outer or middle ear is blocked or damaged, bone conduction thresholds will be better than air conduction hearing levels.
Sensorineural hearing loss occurs when there is damage to the cochlea or to the auditory nerve pathways.
Test method and desired patient response is determined by patient age and developmental level. As children approach age 2 ? years, VRA is no longer effective because it cannot hold the child’s interest for the duration of the test. Preschool: At 2 ? years of age, most children learn games used in conditioned play audiometry (CPA). School-aged Children: At around age 4 years, children are ready to respond in a more adult-like manner known as a voluntary response.
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. The ear canal, ear drum, and the tiny bones in the middle ear make up the conductive system and any hearing loss caused by a problem in one or more of these areas is called a conductive hearing loss. 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. 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 hearing threshold is determined to be the lowest intensity (dBHL) at which multiple presentations of a frequency specific tone were detected 50% of the time.
For example, the sound “sss” presents at a high frequency, while an “ooo” presents at a lower frequency. Air conduction testing involves the use of headphones, insert earphones, or speakers to deliver sounds to the ear canal through the middle ear and into the inner ear.
Conductive hearing loss is defined as air conduction thresholds greater than 15 dB (outside the normal range) with bone conduction thresholds within the normal range. Consistent, reliable behavioral threshold testing is possible with children as young as 6 months developmental age. 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.

Unlike a sensorineural hearing loss a conductive hearing loss occurs because the sound entering the ear is reduced or dampened by the obstruction; there is no damage to the delicate nerves in the inner ear. Rarely, there may be more serious causes of conductive hearing loss and these conditions, if left unidentified and untreated, may have profound medical consequences. Hearing aids are often the best answer when surgery is not possible, because they significantly improve hearing and are convenient.


The shaded region on the audiogram shows the range where most conversational speech occurs.
In general, a red “O” is used to represent the right ear while a blue “X” represents the left ear.
To the right is an audiogram of an individual with conductive hearing loss in the left ear.
Traditionally, the test setting involves the child and the audiologist sitting at a small table in a sound booth.
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.
A conductive hearing loss can often be partially or completely reversed with medical intervention.
Though usually not necessary, implantable hearing devices such as a bone-anchored hearing aid are an excellent alternative if neither surgery nor a traditional hearing aid are feasible options.
In bone conduction testing a bone oscillator is placed behind the ear on the mastoid bone to deliver sounds directly to the inner ear by vibration, bypassing the outer and middle ear. Notice that air conduction results show a moderate hearing loss while bone conduction results show that the cochlea and sensorineural pathway are responding within the range of normal hearing sensitivity. The child is trained to respond to a stimulus by performing a task such as putting block in a bucket or a peg in a board.
Practically, this is a very uncommon situation, of much more interest to diagnosticians than patients. Normal hearing is defined as having threshold at an intensity greater than or equal to 15dB HL. Comparing air conduction and bone conduction thresholds helps determine whether a hearing loss is classified conductive, sensorineural, or mixed. In a sound-treated room, an audiologist can quickly train a child to look towards something interesting like a puppet or video when a sound is heard (i.e. In cases where a child will not or cannot wear earphones for ear-specific threshold testing, sounds may be presented via speakers (in the “soundfield”).
This technique enables audiologists to draw general conclusions about a child’s hearing but does not give any ear-specific information.
Arrows connected to audiogram symbols indicate a no response value, indicating that at the specified frequency no response was detected. The Guidelines for Audiometric Symbols can be found on the website of the American Speech-Language-Hearing Association (ASHA).
