What is the prevalence of Vestibular Schwannoma?
How many people does Vestibular Schwannoma affect? Does it have the same prevalence in men and women? And in the different countries?
Vestibular Schwannoma, also known as acoustic neuroma, is a relatively rare benign tumor that develops on the vestibular nerve. It accounts for approximately 6-8% of all intracranial tumors.
Although considered uncommon, the prevalence of Vestibular Schwannoma is estimated to be around 1 in 100,000 individuals per year. It typically affects adults aged 30-60 years, with a slightly higher incidence in women.
Early detection and appropriate management are crucial for minimizing potential complications and preserving hearing function. Symptoms may include hearing loss, tinnitus, dizziness, and balance problems.
Vestibular Schwannoma, also known as acoustic neuroma, is a relatively rare benign tumor that develops on the vestibular nerve responsible for balance and hearing. It arises from Schwann cells, which produce the protective covering (myelin) around nerve fibers. While the exact cause is unknown, it is believed to be associated with a genetic condition called neurofibromatosis type 2 (NF2) in some cases.
The prevalence of Vestibular Schwannoma is estimated to be around 1 in 100,000 individuals. Although it can occur at any age, it is most commonly diagnosed between the ages of 30 and 60. The tumor typically grows slowly, and its size can vary from very small to large enough to press against nearby structures in the brain, leading to symptoms such as hearing loss, tinnitus (ringing in the ears), dizziness, and balance problems.
Early detection and diagnosis are crucial for managing Vestibular Schwannoma. Magnetic resonance imaging (MRI) scans are commonly used to identify and monitor the tumor's growth. Treatment options depend on various factors including tumor size, symptoms, and the patient's overall health. These may include observation with regular monitoring, surgical removal, or radiation therapy.
While Vestibular Schwannoma is a relatively uncommon condition, it is important to be aware of its symptoms and seek medical attention if any concerning signs arise. Consulting with healthcare professionals can provide appropriate guidance and ensure timely intervention if necessary.
