otosclerosis 7

Otosclerosis Description

Otosclerosis describes a condition of abnormal bone growth around one of the three small bones in the middle ear space called the “stapes.” [7]

This abnormal bone growth can cause hearing loss by disrupting the normal functioning of the middle ear. The stapes bone plays a crucial role in transmitting sound vibrations from the eardrum to the inner ear, and any abnormalities in this process can lead to hearing difficulties.

Causes and Effects

The exact causes of otosclerosis are not fully understood, but it is believed to be related to irregular turnover of the bone that surrounds the inner ear. This condition can lead to hearing loss or ringing in the ears (tinnitus). [6]

It's worth noting that otosclerosis is an inherited disease that affects the bone of the ear, and its symptoms can vary from person to person. [5]

Main Symptom of Otosclerosis

The main symptom of otosclerosis is hearing loss. At first, you may notice that you can't hear low-pitched sounds or people whispering [7].

Other Possible Symptoms

In addition to hearing loss, other possible symptoms of otosclerosis include:

• Tinnitus (ringing or buzzing in the ears)
• Vertigo (dizziness)

These symptoms can vary from person to person and may not be present in all cases of otosclerosis.

Diagnostic Tests for Otosclerosis

Otosclerosis can be diagnosed through various tests that help identify the condition and rule out other possible causes of hearing loss.

• Hearing Tests: Hearing tests are essential in diagnosing otosclerosis. There are specific patterns of hearing loss that are suggestive of otosclerosis, such as a hearing loss that affects all frequencies (pitches) [5].
• Tympanometry Test: A tympanometry test is also used to diagnose otosclerosis. This test involves gently placing a probe into the ear that changes the pressure against the eardrum, and a readout from the test helps the doctor assess the condition of the middle ear [4].
• Imaging Tests: Imaging tests such as CT scans may be used to look for other causes of hearing loss and to confirm the diagnosis of otosclerosis. A temporal-bone CT scan may be used to examine the bones and tissues inside the ear [2, 8].

These diagnostic tests help doctors identify the condition and determine the best course of treatment.

Unfortunately, there is no medicine that can reverse the effects of otosclerosis [7]. In some people who have progressive inner ear injury, fluoride therapy may be recommended to help slow down the progression of symptoms [5][8][9].

However, it's essential to note that sodium fluoride and calcium are the only drugs used in the treatment of otosclerosis, but their effectiveness is still being researched [4][6]. Some studies have suggested that taking fluoride, calcium, and vitamin D supplements may help to slow the progression of symptoms, but more research is needed to confirm this [8].

It's also worth mentioning that steroid therapy is not typically used in the treatment of otosclerosis, unlike in cases of sensorineural hearing loss [1]. If you have been diagnosed with otosclerosis, it's crucial to consult with an ear, nose, and throat (ENT) specialist or a hearing specialist for personalized advice on managing your condition.

Differential Diagnosis of Otosclerosis

Otosclerosis, a condition characterized by abnormal bone growth in the middle ear, can be challenging to diagnose due to its similarity with other conditions. The differential diagnosis for otosclerosis includes:

• Paget disease: A condition that affects the bones and can cause hearing loss similar to otosclerosis.
• Fibrous dysplasia: A rare disorder where normal bone is replaced by fibrous tissue, leading to hearing loss and other symptoms.
• Osteogenesis imperfecta: A genetic disorder that causes fragile bones and can lead to hearing loss, among other complications.

These conditions share similar symptoms with otosclerosis, such as hearing loss and abnormalities in the middle ear. Therefore, a comprehensive diagnosis is essential to rule out these differential diagnoses and confirm the presence of otosclerosis.
