Acoustic Neuroma
Acoustic Neuroma
Acoustic Neuroma (pronounced: a-koo-stik noo-roh-muh), also known as Vestibular Schwannoma, is a noncancerous and usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain.
Etymology
The term "Acoustic Neuroma" is derived from the Greek words "akoustikos" meaning "of or for hearing", and "neuroma" meaning "tumor of the nerve". The term "Vestibular Schwannoma" is derived from the Latin word "vestibulum" meaning "entrance", and "Schwannoma" named after the German physiologist Theodor Schwann, who discovered the cells (Schwann cells) that the tumor originates from.
Symptoms
Symptoms of an Acoustic Neuroma include loss of hearing in the affected ear, ringing in the ear (tinnitus), and problems with balance. In rare cases, an Acoustic Neuroma can grow large enough to compress the brainstem and become life-threatening.
Diagnosis
Diagnosis of an Acoustic Neuroma is typically made through a physical examination, hearing tests, and imaging tests such as MRI (Magnetic Resonance Imaging) or CT scan (Computed Tomography).
Treatment
Treatment options for an Acoustic Neuroma include regular monitoring, radiation and surgical removal. The choice of treatment depends on the size and growth of the tumor, as well as the patient's overall health and personal preferences.
