A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
There are conflicting studies on the association between acoustic neuromas and cellular phone use and repeated exposure to loud noise. In 2011, an arm of the World Health Organization released a statement listing cell phone use as a low grade cancer risk. The Acoustic Neuroma Association recommends that cell phone users use a hands-free device.
Patients with these tumors often have signs and symptoms corresponding to compression of both nerves. Acoustic neuroma (vestibular schwannoma) – benign neoplasm of Schwann cells affecting the vestibulocochlear nerve; Meningioma – benign tumour of the pia and arachnoid mater
Acoustic trauma can cause temporary or permanent hearing loss, relentless ringing in the ears, and reduce our quality of life. However, there are ways to protect your hearing and prevent acoustic ...
Acoustic neuroma - a slow-growing, benign tumor of the acoustic nerve. [2] Symptoms, which most often start after the age of 30, can include dizziness, headache, vertigo, loss of balance, ringing sensations, and numbness. [3] Ganglioneuroma - a tumor of the sympathetic nerve fibers arising from neural crest cells. [4]
Known causes include genetics, maternal illness and injury. Examples of these causes are physical trauma, acoustic neuroma, maternal prenatal illness such as measles, labyrinthitis, microtia, meningitis, Ménière's disease, Waardenburg syndrome, mumps (epidemic parotitis),mastoiditis or due to an overstrained nervus vestibulocochlearis after a brain surgery to close to the nerve.
One option includes treatment for a disease or disorder that may be contributing to the balance problem, such as ear infection, stroke, multiple sclerosis, spinal cord injury, Parkinson's, neuromuscular conditions, acquired brain injury, cerebellar dysfunctions and/or ataxia, or some tumors, such as acoustic neuroma. Individual treatment will ...
Although the pathophysiology of CSWS is not fully understood, it is usually caused by neurological injury, most commonly aneurysmal subarachnoid hemorrhage. [5] It is also reported after surgery for pituitary tumor, acoustic neuroma, calvarial remodeling, glioma and with infections including tuberculous meningitis, viral meningitis, metastatic carcinoma, and cranial trauma.
