Acoustic neuroma, also known as vestibular schwannoma, is a non-cancerous tumor that grows on the vestibular nerve, which is responsible for transmitting information about balance and spatial orientation from the inner ear to the brain. This type of tumor usually grows slowly over many years and is often benign, but it can still cause serious health problems if it grows too large.
The exact cause of acoustic neuromas is not known, but they are believed to be caused by a genetic mutation or changes in the DNA of cells within the nerve sheath.
Treatment options for acoustic neuromas depend on the size and location of the tumor, as well as the severity of symptoms. Options may include monitoring the tumor with regular imaging tests, radiation therapy, or surgical removal of the tumor.
