Key Points about Otosclerosis:
- Definition: Otosclerosis is a progressive ear condition where abnormal bone growth in the middle ear, particularly around the stapes bone, leads to conductive hearing loss. In some cases, the condition can affect the inner ear, resulting in sensorineural hearing loss.
- Causes: The exact cause of otosclerosis is unknown, but it is believed to have a genetic component and may be influenced by hormonal changes, viral infections, and immune factors. It is more common in females and often presents in early to middle adulthood.
- Symptoms: The main symptom is gradual hearing loss, which typically affects both ears but can be unilateral. Patients may also experience tinnitus, a sensation of fullness in the ear, and balance issues. Hearing loss may worsen during pregnancy due to hormonal changes.
- Investigations: Diagnosis is primarily clinical, supported by audiometry, which reveals a conductive hearing loss pattern. Tympanometry may show reduced compliance of the middle ear system. CT scans can help visualize the abnormal bone growth around the stapes.
- Management: Management includes hearing aids for mild cases and surgical intervention, such as stapedectomy or stapedotomy, for more severe cases. These procedures aim to bypass or remove the immobilized stapes bone to improve hearing. Cochlear implants may be considered in advanced cases with significant sensorineural involvement.
- Complications: Complications of otosclerosis can include persistent hearing loss, dizziness, and risks associated with surgical intervention, such as taste disturbances, tinnitus, and, rarely, total hearing loss. Early diagnosis and appropriate treatment can help improve outcomes.
