You’re finding it increasingly difficult to follow conversations, and voices sound muffled, quiet, or distorted, even though the environment hasn’t actually gotten any louder. Many people who experience these changes initially attribute them to stress or external factors. But sometimes there’s more to it: otosclerosis. This rare middle ear disorder often begins gradually and progressively impairs hearing.

Otosclerosis is a rare disorder of the middle ear in which the normally movable ossicles become abnormally ossified. In a healthy middle ear, these ossicles transmit sound to the inner ear. If they become immobile, they can no longer transmit sound properly, and our hearing gradually deteriorates. This condition is referred to as conductive hearing loss.

Hearing loss begins gradually—usually on one side at first, then on both sides—and can lead to complete deafness if the hair cells in the inner ear are destroyed by otosclerosis. Of the nearly 10 percent of the population who have abnormalities in the middle and inner ear, only 1 percent are affected by otosclerosis. Among them, about twice as many women as men are affected.

Because ossification in this rare condition can begin in different parts of the ear, symptoms may vary. The changes often begin long before symptoms appear.

• Progressive hearing loss in one ear, and later usually in both ears
• In advanced stages, tinnitus may also occur, often in the low-frequency range
• Cracking or whistling sounds in the ear
• Dizziness and nausea

This rare middle ear condition often occurs between the ages of 20 and 40 and can gradually worsen. The exact causes are not fully understood. Genetic factors and hormonal influences are suspected, such as:

• Previous viral infections such as measles, mumps, and rubella
• Autoimmune diseases
• Osteogenesis imperfecta
• Afamily history of this rare condition
• Pregnancy
• Hormone medications
• Previous hearing trauma and fractures in the ear

Good hearing is an important component of quality of life and independence: It is essential for communication, social participation, and safety in everyday life. If hearing loss goes untreated, it can have long-term consequences such as isolation, physical discomfort, and mental stress.

Because otosclerosis develops gradually, it is often not diagnosed until it is advanced. The ossification in the ear continues unchecked until then. The limitations in daily life become clearly apparent:

• Conversations in groups become increasingly tiring
• Sounds seem distorted or muffled
• It’s hard to understand phone calls
• Misunderstandings at work or in personal life become more frequent
• Those affected withdraw from social situations

It is therefore important to pay attention to symptoms and consult an ENT specialist early on. An early diagnosis leads to significantly better treatment outcomes, prevents potential complications—such as complete hearing loss—in a timely manner, and thus avoids unnecessary limitations in daily life.

To make a diagnosis, the ENT specialist first conducts a medical history interview. Using various examination methods—such as otoscopy (examination of the ear), tuning fork tests to locate the hearing problem in the ear, tone and speech audiograms (hearing tests), tests of eardrum mobility (tympanometry), as well as magnetic resonance imaging (MRI) and computed tomography (CT) scans, the ENT specialist then forms an accurate picture of the patient’s hearing status.

This rare middle ear condition cannot be cured with medication. There are only a few treatment options:

1. Cortisone therapy in the early stages to slow the ossification.
2. Surgeryin which the stiffened stapes is partially (stapedotomy) or completely (stapedectomy) replaced with a movable prosthesis so that it can transmit sound again.
3. Assistive hearing devices, including hearing training

To date, the most promising treatment is surgery under local anesthesia, which restores the mobility of the ossicles in the ear. The choice of treatment depends on the stage of the rare condition and the individual’s needs. Modern hearing aids support the best possible hearing and can help alleviate side effects such as tinnitus.

Modern hearing aids are now highly sophisticated systems that do much more than simply amplify sound. In cases of otosclerosis, they can help compensate for hearing loss by:

• selectively amplifying frequencies that are difficult to hear
• reducing background noise
• supporting directional hearing
• adapting to different listening situations
• improving speech understanding
• Accompanying tinnitus can be alleviated through targeted therapies or hearing aids with built-in noise generators.

In addition to ENT specialists, hearing care professionals are your most important points of contact when it comes to otosclerosis. They often work with patients over a long period of time and help them find the best possible hearing solution. This includes:

• Conducting and evaluating hearing tests
• Selecting and fitting hearing aids to meet individual needs
• Fine-tuning for various everyday situations
• Advice on additional treatment options

This professional support ensures that, despite this rare condition, you can actively participate in life with good hearing.

There is no specific way to prevent otosclerosis. However, early diagnosis helps ensure timely and targeted intervention. Regular hearing tests and checkups with specialized doctors can help detect abnormalities early and initiate any necessary surgery to, ideally, prevent otosclerosis from progressing to a severe stage. This is especially important for people with a family history of otosclerosis. Hearing care professionals support you through every stage of otosclerosis with personalized, state-of-the-art hearing solutions.
