Vestibular schwannoma
Vestibular Schwannoma
Vestibular Schwannoma (pronunciation: ves-ti-byoo-lar shwah-noh-muh), also known as Acoustic Neuroma, is a benign, usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear.
Etymology
The term "Vestibular Schwannoma" is derived from three words: "Vestibular", referring to the vestibular system which is responsible for the body's sense of balance; "Schwann", named after Theodor Schwann, a German physiologist who discovered the cells (Schwann cells) that form the myelin sheath around the peripheral nerves; and "oma", a suffix used in medical terminology to denote a tumor or growth.
Symptoms
The symptoms of Vestibular Schwannoma can include hearing loss, tinnitus (ringing in the ear), and balance disturbances. More severe symptoms can occur if the tumor grows large enough to compress the brainstem.
Diagnosis
Diagnosis of Vestibular Schwannoma typically involves a physical examination, hearing tests, and imaging tests such as MRI or CT scan.
Treatment
Treatment options for Vestibular Schwannoma include observation, surgery, and radiation therapy. The choice of treatment depends on the size of the tumor, the patient's overall health, and the severity of the symptoms.
