Vestibular schwannomas, also known as acoustic neuromas, are benign tumors that develop on the vestibular nerve, which connects the inner ear to the brain. These tumors can cause hearing loss, tinnitus, dizziness, and other neurological symptoms. At SHIFAA PAN African Hospitals, our Neurology Department specializes in the diagnosis and treatment of vestibular schwannomas, providing personalized care and advanced surgical interventions to optimize outcomes for patients.

Symptoms:

The symptoms of vestibular schwannomas may include gradual hearing loss, tinnitus (ringing in the ears), dizziness, imbalance, facial weakness or numbness, and headaches. Early detection and intervention are crucial for preserving hearing function and preventing complications associated with tumor growth.

Investigation and Diagnosis:

Diagnosing vestibular schwannomas involves a comprehensive evaluation, including a detailed medical history, physical examination, hearing tests (audiometry), and imaging studies such as MRI with gadolinium enhancement. Our neurologists collaborate with otolaryngologists and neuroradiologists to accurately diagnose vestibular schwannomas and develop individualized treatment plans.

Procedure:

Treatment for vestibular schwannomas may include observation, radiation therapy (stereotactic radiosurgery), or surgical excision. Surgery, known as microsurgical resection, aims to remove the tumor while preserving neurological function and hearing whenever possible. Our neurosurgeons utilize state-of-the-art surgical techniques, such as the retrosigmoid approach or middle fossa approach, to access and remove vestibular schwannomas with precision and minimal risk to surrounding structures.

Recovery Time:

Recovery time after surgery for vestibular schwannomas varies depending on the size and location of the tumor, as well as individual patient factors. Some patients may experience improvement in symptoms shortly after surgery, while others may require ongoing rehabilitation and supportive care. Long-term follow-up is essential to monitor for tumor recurrence and assess hearing function and neurological status.

 

What is a vestibular schwannoma?

A vestibular schwannoma, also known as an acoustic neuroma, is a benign tumor that develops on the vestibular nerve, which connects the inner ear to the brain.

 

What are the symptoms of vestibular schwannomas?

Symptoms of vestibular schwannomas may include gradual hearing loss, tinnitus (ringing in the ears), dizziness, imbalance, facial weakness or numbness, and headaches.

 

How are vestibular schwannomas diagnosed?

Diagnosing vestibular schwannomas involves a comprehensive evaluation, including a detailed medical history, physical examination, hearing tests (audiometry), and imaging studies such as MRI with gadolinium enhancement.

 

What is the treatment for vestibular schwannomas?

Treatment for vestibular schwannomas may include observation, radiation therapy (stereotactic radiosurgery), or surgical excision (microsurgical resection).

 

Can surgery preserve hearing in patients with vestibular schwannomas?

In some cases, surgery for vestibular schwannomas can preserve hearing, especially when the tumor is small and located away from the cochlear nerve. However, the extent of hearing preservation depends on various factors, and not all patients may retain their hearing after surgery.

 

Are there risks associated with surgery for vestibular schwannomas?

Risks associated with surgery for vestibular schwannomas include hearing loss, facial nerve injury, balance disturbances, cerebrospinal fluid leakage, and infection. The surgical team carefully evaluates each patient’s case to minimize risks and optimize outcomes.

 

What is the prognosis for patients with vestibular schwannomas?

The prognosis for patients with vestibular schwannomas depends on various factors, including the size and growth rate of the tumor, the extent of hearing loss, and the success of treatment. Early detection and comprehensive management can improve outcomes and quality of life for many patients.
