How Do You Spell VESTIBULAR SCHWANNOMA?

1. Vestibular Schwannoma, also referred to as acoustic neuroma, is a non-malignant or benign tumor that arises on the vestibular nerve, which is responsible for carrying signals from the inner ear to the brain. The vestibular nerve is primarily involved in maintaining balance and facilitating hearing.

   This type of tumor typically develops from Schwann cells, the supportive cells that insulate and protect nerves. It specifically affects the Schwann cells surrounding the vestibular portion of the eighth cranial nerve, known as the vestibulocochlear nerve or auditory nerve.

   Vestibular Schwannoma grows slowly and gradually, usually within the internal auditory canal, a narrow bony passage connecting the ear to the brain. As the tumor continues to grow, it may eventually extend into the nearby region called the cerebellopontine angle, where the vestibular nerve and other cranial nerves are located.

   Common symptoms of vestibular schwannoma may include hearing loss, tinnitus (ringing in the ear), dizziness, balance problems, and in more advanced cases, facial numbness or weakness. These symptoms primarily arise due to the compression of the vestibulocochlear nerve and other adjacent structures.

   Treatment options for vestibular schwannoma can vary depending on factors such as the size and growth rate of the tumor, as well as the overall health and hearing of the affected individual. Options may range from observation or monitoring, especially for small tumors with minimal symptoms, to surgical removal or radiation therapy.

Common Misspellings for VESTIBULAR SCHWANNOMA

The word "vestibular schwannoma" has its etymology rooted in medical terminology. It is derived from two main components:

1. Vestibular: The term "vestibular" is derived from the Latin word "vestibulum", which means "entrance hall" or "forecourt". In anatomy, it refers to the vestibule, a part of the inner ear responsible for balance and spatial orientation.

2. Schwannoma: The term "schwannoma" refers to a type of tumor that arises from Schwann cells, which are a specific type of glial cells that form the myelin sheath around peripheral nerves.

Therefore, "vestibular schwannoma" is a medical term used to describe a benign tumor that develops from Schwann cells and affects the vestibular nerve, which is responsible for balance and hearing. It is also commonly referred to as an acoustic neuroma.
