Pathways to Clearer Sounds: Treatment and Surgery for Otosclerosis

Otosclerosis is a condition that affects the middle ear, leading to hearing loss. Fortunately, there are various treatment options available, including surgical interventions, which can greatly improve the quality of life for individuals with this condition. In this article, we will discuss the different pathways to clearer sounds through the treatment and surgery for otosclerosis.

Understanding Otosclerosis

Otosclerosis is a progressive disorder that primarily affects the bones of the middle ear. In individuals with otosclerosis, abnormal bone growth occurs around the stapes bone, preventing it from vibrating properly. This leads to hearing loss as sound waves cannot be effectively transmitted to the inner ear.

Otosclerosis can have a significant impact on an individual’s daily life. It can make it difficult to engage in conversations, enjoy music, and even perform everyday tasks. Understanding the underlying cause of otosclerosis is crucial in determining the most appropriate treatment pathway.

Symptoms of Otosclerosis

The symptoms of otosclerosis can vary from mild to severe and may include:

  • Gradual hearing loss, which may initially be more pronounced when listening to low-pitched sounds. This can make it challenging to follow conversations, especially in noisy environments.
  • Tinnitus, a ringing or buzzing noise in the ear. This persistent sound can be distracting and interfere with concentration and sleep.
  • Dizziness or problems with balance. This can affect the individual’s ability to move around confidently and may increase the risk of falls.

It is important to note that the symptoms of otosclerosis can be similar to other ear conditions. Therefore, it is crucial to consult with a healthcare professional for an accurate diagnosis. An ear, nose, and throat specialist can perform a thorough examination, which may include a hearing test and imaging studies, to confirm the presence of otosclerosis.

Non-Surgical Treatments for Otosclerosis

Before considering surgical options, non-surgical treatments may be explored to manage the symptoms of otosclerosis. These can include:

Hearing Aids

Hearing aids can effectively amplify sounds and improve hearing in individuals with otosclerosis. They work by capturing external sounds and converting them into electrical signals, which are then transmitted to the ear through a small speaker. Hearing aids can be customized to the individual’s specific hearing needs, providing a tailored solution for their hearing loss.

In addition to amplifying sounds, modern hearing aids also come with advanced features such as noise reduction, directional microphones, and feedback cancellation. These features help individuals with otosclerosis to better understand speech, filter out background noise, and prevent the annoying feedback whistling sound.

Bone-Anchored Hearing System (BAHS)

A BAHS is another non-surgical option that can help individuals with otosclerosis. This system consists of a small device that is attached to a titanium implant placed behind the ear. The device transmits sound vibrations directly to the inner ear, bypassing the middle ear to improve hearing.

The BAHS works by capturing sounds through a microphone in the external device. The sound is then converted into vibrations, which are transmitted through the implant and directly stimulate the inner ear. This direct stimulation can be particularly beneficial for individuals with otosclerosis, as it bypasses the areas of the middle ear affected by the abnormal bone growth.


While there is no medication that can cure otosclerosis, certain medications may help manage its symptoms. Fluoride supplements, for example, have been found to slow down the progression of the condition in some cases. Fluoride helps to strengthen the bone and can potentially reduce the abnormal bone growth associated with otosclerosis.

Medications that improve blood flow to the inner ear can also be prescribed to alleviate symptoms such as tinnitus. These medications, known as vasodilators, help to increase blood circulation, delivering essential nutrients and oxygen to the inner ear. By improving blood flow, vasodilators may reduce the severity of tinnitus and improve overall hearing function.

Surgical Interventions for Otosclerosis

Surgery may be recommended when non-surgical treatments do not provide sufficient relief or when the condition significantly affects an individual’s quality of life. The two most common surgical interventions for otosclerosis are stapedectomy and stapedotomy.


A stapedectomy is a surgical procedure where the stapes bone is completely removed and replaced with a prosthesis. This prosthesis allows sound vibrations to pass directly to the inner ear, bypassing the abnormal bone growth.

During the procedure, a small incision is made behind the ear, and the middle ear is accessed. The stapes bone is carefully removed, and the prosthesis is placed in its position. The incision is then closed, and the patient is required to refrain from any strenuous activities for a few weeks to facilitate proper healing.

Stapedectomy is a highly effective surgical intervention for otosclerosis, with a success rate of over 90%. It can significantly improve hearing and restore the individual’s quality of life. However, it is important to note that like any surgical procedure, stapedectomy carries some risks, including infection, damage to the facial nerve, and sensorineural hearing loss.


Stapedotomy is a less invasive surgical procedure compared to stapedectomy. Instead of removing the entire stapes bone, a small hole is created in it. The prosthesis is then inserted into this hole, allowing for improved transmission of sound waves.

Similar to stapedectomy, stapedotomy requires a small incision behind the ear. The procedure is performed using a microscope or an endoscope for enhanced precision. The recovery process is also similar, with postoperative care aimed at protecting the ear from trauma or infection.

Stapedotomy is generally recommended for individuals with otosclerosis who have a specific type of abnormal bone growth that makes them unsuitable candidates for stapedectomy. The success rate of stapedotomy is also high, with most individuals experiencing significant improvement in their hearing abilities.

Risks and Considerations

As with any surgical procedure, there are risks and considerations associated with surgical interventions for otosclerosis. These can include:

  • Infection at the surgical site. Steps are taken to minimize the risk of infection, including the use of sterile techniques and antibiotics.
  • Damage to the facial nerve. Surgeons take great care to avoid the facial nerve during the procedure, but there is a small risk of damage.
  • Hearing loss or worsening of existing hearing loss. While the goal of surgery is to improve hearing, there is a small risk of hearing loss due to complications or unforeseen factors.
  • Tinnitus. Surgery can sometimes trigger or worsen tinnitus, although this is rare.
  • Balance problems. The inner ear plays a role in balance, and surgery in this area can potentially affect balance. However, balance problems after otosclerosis surgery are uncommon.
  • Perilymphatic fistula, a condition where there is a leakage of fluid from the inner ear. This is a rare complication but may require further treatment if it occurs.
  • Sensorineural hearing loss, a type of hearing loss that occurs due to damage to the inner ear or auditory nerve. While rare, this complication can occur during surgery.

It is essential to have a thorough discussion with an ear, nose, and throat specialist to weigh the potential risks and benefits before deciding on surgical intervention. The specialist will evaluate the individual’s specific condition and medical history to determine the most appropriate surgical approach.


Otosclerosis is a condition that can significantly impact an individual’s hearing abilities and overall quality of life. While non-surgical treatments, such as hearing aids and BAHS, can provide relief for some, surgical interventions like stapedectomy and stapedotomy are often necessary for long-term improvement.

Consulting with a healthcare professional is crucial in determining the most appropriate treatment pathway for otosclerosis. By understanding the available options and carefully considering the risks and benefits, individuals can find their pathway to clearer sounds and improved hearing.
