Otosclerosis
Otosclerosis can cause hearing loss in one or both ears. When a bone in your middle ear repeatedly restores itself, it interferes with sound’s ability to travel through your ear. Our ear, nose and throat specialists are experienced in identifying the cause and delivering effective, personalised treatment.
What is otosclerosis?
Otosclerosis occurs when a tiny triangular bone (the stapes bone) deep inside the ear, called the stapes, fuses with surrounding bone tissue. This reduces the ability of the other bones in the ear to vibrate as they should, affecting the way that sound travels through your ear. This leads to reduced volume and sound quality.
The condition usually affects both ears, but in most cases, one ear is more severely affected than the other – around 10 to 15% of people may only have symptoms in one ear.
It’s a common cause of hearing loss in younger adults, with symptoms usually starting between the ages of 30 to 50. Hearing loss may stay relatively mild, but in most cases it does get worse – either quickly or over many years.
At Welbeck, our consultants diagnose and treat patients with symptoms including dizziness, tinnitus and hearing loss in our state-of-the-art Ear, Nose & Throat centre.
More information
The most common symptom of otosclerosis is gradual hearing loss in 1 or both ears, often over several years. You might notice that you can’t hear whispering or low-pitched tones or sounds, often ask people to repeat themselves, or need to have the radio or television on a higher and higher volume.
You may also experience:
ringing, buzzing, or other noises in 1 or both ears (tinnitus)
dizziness
balance problems
speaking quietly because your voice sounds loud to you
It's not known why otosclerosis happens, but it may be passed on through genes. You’re more likely to get otosclerosis if a close relative has it. But some people with otosclerosis don’t have a family history.
Risk factors for otosclerosis include:
being female – twice as many women as men are diagnosed with otosclerosis
age and race – the condition is most common in white women between the ages of 20 and 45
having brittle bone disease (osteogenesis imperfecta)
having had measles – more research is needed, but there may be a link
Diagnosing otosclerosis usually involves an initial consultation where our ear, nose and throat specialist will:
Take a medical history to understand your health.
Get a full understanding of your symptoms and how they affect you – for example, what they are, what makes them worse or better, and how they affect your daily life, such as sleeping and working.
Examine your ears.
Review any previous notes or scans.
Talk through their initial findings and what will happen next.
They may recommend running some tests, such as hearing tests, like an audiogram to check which pitches of sound you can hear and a check of your eardrum function, balance tests, and a CT scan.
As this condition appears suddenly and seems to be linked to a family history or other health conditions, there’s no way to prevent it.
It’s important to be aware that otosclerosis causes increased hearing loss as the condition progresses. If you need treatment or surgery that has side effects or potential risks, your consultant will always talk these through with you, based on your specific health history.
There are several management options available for otosclerosis, including:
Hearing aids to help improve the quality and volume of the sound you hear. They won’t prevent your otosclerosis from getting worse, but many people manage well with hearing aids that are adjusted as their hearing changes.
Stapes surgery may be performed under general or local anaesthetic, to remove the whole or part of the stapes bone, and replace it so it doesn’t keep growing to affect hearing.
Cochlear implants can be placed to bypass your inner ear structure and create a new pathway through which sounds can travel to your brain.

Frequently asked questions
Make an appointment with a Welbeck specialist if:
you notice a sudden or big change in your hearing
you think your hearing is gradually getting worse
you have tinnitus regularly, all the time, or it’s getting worse
your tinnitus is affecting your sleep or concentration
The hearing results of stapes surgery for otosclerosis can be excellent, with very good results possible in 80% to 90% of cases.
Some women say their otosclerosis symptoms get worse when they’re pregnant. Scientists think there may be a link with high levels of the female hormone oestrogen in the body during pregnancy.
If you have otosclerosis and are planning a pregnancy, are worried that pregnancy will make your condition worse, or notice hearing changes, talk to your consultant about monitoring. Some women with a pre-existing risk who have not had symptoms before may notice they start during pregnancy.
Otosclerosis is likely to get worse over time if you don’t have treatment. In some cases, it can spread to your inner ear and cause cochlear otosclerosis. You can discuss your options with your consultant and decide together whether monitoring, a hearing aid, or surgical options might work best for your case.
