Also known as: Otospongiosis and Hearing loss - otosclerosis
- Hearing loss (slow at first, but worsens over time)
- Ringing in the ears (tinnitus)
- Vertigo or dizziness
- A total replacement is called a stapedectomy.
- Sometimes only part of the stapes is removed and a small hole is made in the bottom of it. This is called a stapedotomy. Sometimes a laser is used to help with the surgery.
- DO NOT blow your nose for 2 to 3 weeks after surgery.
- Avoid people with respiratory or other infections.
- Avoid bending, lifting, or straining, which may cause dizziness.
- Avoid loud noises or sudden pressure changes, such as scuba diving, flying, or driving in the mountains until you have healed.
- Complete deafness
- Funny taste in the mouth or loss of taste to part of the tongue, temporary or permanent
- Infection, dizziness, pain, or a blood clot in the ear after surgery
- Nerve damage
- You have hearing loss
- You develop fever, ear pain, dizziness, or other symptoms after surgery
Otosclerosis is an abnormal bone growth in the middle ear that causes hearing loss.
The exact cause of otosclerosis is unknown. It may be passed down through families.
People who have otosclerosis have an abnormal sponge-like bone growing in the middle ear. This growth prevents the ear bones from vibrating in response to sound waves. These vibrations are needed in order for you to hear.
Otosclerosis is the most common cause of middle ear hearing loss in young adults. It typically begins in early to mid-adulthood. It is more common in women than in men. The condition may affect one or both ears.
Risks for this condition include pregnancy and a family history of hearing loss. White people are more likely to develop this condition than people of other races.
Exams and Tests
A hearing test (audiometry/audiology) may help determine the severity of hearing loss.
A special imaging test of the head called a temporal-bone CT may be used to look for other causes of hearing loss.
Otosclerosis may slowly get worse. The condition may not need to be treated until you have more serious hearing problems.
Using some medicines such as fluoride, calcium, or vitamin D may help to slow the hearing loss. However, the benefits of these treatments have not yet been proven.
A hearing aid may be used to treat the hearing loss. This will not cure or prevent hearing loss from getting worse, but it may help with symptoms.
Surgery can cure or improve conductive hearing loss. Either all or part of one of the small middle ear bones behind the eardrum (stapes) is removed and replaced with a prosthesis.
Otosclerosis gets worse without treatment. Surgery can restore some or all of your hearing loss. Pain and dizziness from the surgery go away within a few weeks for most people.
To reduce the risk of complications after surgery:
If surgery does not work, you may have total hearing loss. Treatment for total hearing loss involves developing skills to cope with deafness, and using hearing aids to transmit sounds from the non-hearing ear to the good ear.
Complications may include:
