Conductive Hearing Loss in Wilmington & Southport, NC
What Is Conductive Hearing Loss?
Conductive hearing loss occurs when sound cannot travel effectively through the outer ear, ear canal, eardrum, or middle ear to reach the inner ear. Unlike sensorineural hearing loss, the inner ear and auditory nerve remain intact — the problem lies in the mechanical pathway that conducts sound.
Think of it this way: the hearing system is working, but something is blocking or disrupting the signal before it ever gets there. The good news is that conductive hearing loss is often temporary and, in many cases, can be improved or fully resolved with the right medical treatment.
At Excel Audiology in Wilmington & Southport, NC, Dr. Jason Rickman and our team provide comprehensive hearing evaluations to accurately identify the type and degree of your hearing loss — and connect you with the right next steps.
How Your Ear Conducts Sound
To understand conductive hearing loss, it helps to understand how healthy hearing works. Sound waves enter the outer ear and travel down the ear canal, causing the eardrum to vibrate. Those vibrations move through three tiny bones in the middle ear — the malleus, incus, and stapes — before reaching the fluid-filled inner ear (cochlea). From there, sound is converted into nerve signals and sent to the brain.
When any part of this outer-to-middle-ear pathway is damaged, blocked, or malformed, sound cannot be conducted efficiently. The result is conductive hearing loss.
Common Causes of Conductive Hearing Loss
There are many potential causes of conductive hearing loss. Some are short-term and highly treatable; others require more involved medical or surgical care.
Earwax buildup (cerumen impaction)
Excessive wax that hardens and blocks the ear canal is one of the most common and easily corrected causes.
Middle ear infections (otitis media)
Fluid accumulation behind the eardrum, particularly common in children, can dampen sound transmission.
Swimmer’s ear (otitis externa)
An infection of the outer ear canal that causes swelling and discharge.
Perforated eardrum
A hole or tear in the eardrum, often caused by infection, trauma, or sudden changes in pressure.
Eustachian tube dysfunction
When the tube that equalizes pressure between the middle ear and throat doesn’t function properly, fluid and pressure changes impair hearing.
Otosclerosis
Abnormal bone growth in the middle ear that stiffens the ossicular chain and reduces sound conduction.
Foreign objects in the ear canal
Particularly in young children, objects lodged in the ear can obstruct the path of sound.
Structural abnormalities
Some individuals are born with malformations of the outer ear, ear canal, or middle ear structures (atresia or microtia).
Symptoms of Conductive Hearing Loss
The most common symptom is muffled or reduced hearing — as though sounds are filtered through a barrier. You may also experience:
- Difficulty hearing soft sounds or distant speech
- A sensation of fullness or pressure in the ear
- Your own voice sounding louder or different than usual
- Pain or discomfort in the ear (when infection is present)
- Drainage from the ear canal
- Tinnitus (ringing or buzzing) in some cases
Because many of these symptoms overlap with other conditions, it’s important to have a proper hearing evaluation to confirm the type and cause of hearing loss.
How Is Conductive Hearing Loss Diagnosed?
At Excel Audiology, we use a comprehensive battery of hearing tests to evaluate the entire auditory system and determine whether hearing loss is conductive, sensorineural, or mixed. Diagnostic testing typically includes:
Otoscopy
A visual inspection of the ear canal and eardrum
Tympanometry
Measures eardrum and middle ear function by detecting how the eardrum responds to changes in air pressure
Speech audiometry
Tests how well you understand speech at various volume levels
Pure-tone audiometry
Determines the softest sounds you can hear across frequencies, using both air and bone conduction
Acoustic reflex testing
Evaluates the response of the stapedial muscle to loud sounds
The combination of air conduction and bone conduction testing is key to identifying conductive hearing loss. When bone conduction thresholds are significantly better than air conduction thresholds, it points to a problem in the conductive pathway rather than the inner ear.
Treatment Options for Conductive Hearing Loss
Treatment depends on the underlying cause and can range from simple in-office procedures to medical or surgical referrals.
Earwax removal
If cerumen impaction is the cause, we offer safe professional earwax removal in our office. This alone can restore hearing dramatically.
Surgical intervention
Conditions like a perforated eardrum, otosclerosis, or structural abnormalities may require surgical repair. In these cases, we work closely with ear, nose, and throat (ENT) specialists to coordinate your care.
Medications
Ear infections are typically treated with antibiotics or antifungal medications. Eustachian tube dysfunction may respond to nasal decongestants or steroids.
Hearing aids
For patients who are not candidates for surgery, or who have residual hearing loss after treatment, hearing aids can be highly effective. Because the inner ear is functioning normally in conductive hearing loss, hearing aids often produce excellent results — sounds are amplified and reach the inner ear clearly.
Bone-anchored hearing devices (BAHA)
In cases where conventional hearing aids are not practical (such as canal atresia or chronic ear drainage), bone-anchored devices bypass the outer and middle ear entirely by transmitting sound vibrations directly through the skull to the cochlea.
Conductive vs. Sensorineural vs. Mixed Hearing Loss
It’s important to understand how conductive hearing loss differs from other types:
| Type | Where the Problem Occurs | Typically Reversible? |
|---|---|---|
| Conductive | Outer/middle ear (ear canal, eardrum, ossicles) | Often yes |
| Sensorineural | Inner ear (cochlea) or auditory nerve | Usually permanent |
| Mixed | Both outer/middle ear AND inner ear | Partially |
If you have both conductive and sensorineural components, this is called mixed hearing loss — which requires a coordinated treatment approach addressing both causes.
When to See an Audiologist
Many people delay getting their hearing checked, waiting years before seeking help. But early evaluation and treatment of conductive hearing loss can prevent the condition from worsening and, in many cases, restore hearing before permanent changes occur. You should schedule a hearing evaluation if you:
- Notice sudden or gradual changes in your hearing
- Experience muffled sounds, ear fullness, or pain
- Are frequently asking others to repeat themselves
- Have a history of ear infections, ear surgery, or head trauma
- Are concerned about a child’s hearing development

Frequently Asked Questions
Can conductive hearing loss go away on its own?
In some cases, yes — particularly when caused by fluid from an ear infection or earwax buildup. However, it’s always best to have your hearing evaluated by an audiologist rather than waiting, since some causes can worsen or cause permanent damage if left untreated.
Is conductive hearing loss permanent?
Conductive hearing loss is often temporary and treatable, especially when the cause is addressed promptly. In rare cases involving structural damage or abnormalities, some degree of permanent hearing loss may remain.
Can hearing aids help conductive hearing loss?
Yes. When medical or surgical treatment is not an option, hearing aids are very effective for conductive hearing loss because the inner ear itself is functioning normally. Sound simply needs to be amplified enough to overcome the blockage or structural issue.
How is conductive hearing loss different from sensorineural hearing loss?
Conductive hearing loss involves the outer or middle ear and is often treatable or reversible. Sensorineural hearing loss involves the inner ear or auditory nerve and is typically permanent, though manageable with hearing aids or cochlear implants.
What is mixed hearing loss?
Mixed hearing loss occurs when a person has both conductive and sensorineural hearing loss at the same time. This requires both medical management of the conductive component and audiological support (hearing aids) for the sensorineural component.
