Enlarged Vestibular Aqueduct (EVA) is a medical condition that affects the inner ear. It is one of the most common forms of congenital inner ear malformations and is often associated with sensorineural hearing loss.
Definition[edit]
An Enlarged Vestibular Aqueduct is a condition where the vestibular aqueduct, a bony canal in the inner ear, is larger than normal. This can lead to an increase in the amount of fluid in the inner ear, which can cause hearing loss.
Symptoms[edit]
The symptoms of an Enlarged Vestibular Aqueduct can vary greatly from person to person. Some people may experience no symptoms at all, while others may have severe hearing loss. Other symptoms can include tinnitus, vertigo, and balance problems.
Causes[edit]
The exact cause of an Enlarged Vestibular Aqueduct is unknown. However, it is believed to be a congenital condition, meaning it is present at birth. It may also be associated with other inner ear abnormalities.
Diagnosis[edit]
Diagnosis of an Enlarged Vestibular Aqueduct is typically made through imaging studies, such as a CT scan or MRI. These tests can show the size of the vestibular aqueduct and any associated abnormalities.
Treatment[edit]
There is currently no cure for an Enlarged Vestibular Aqueduct. Treatment is typically focused on managing symptoms and preventing further hearing loss. This can include the use of hearing aids or cochlear implants.
Prognosis[edit]
The prognosis for individuals with an Enlarged Vestibular Aqueduct can vary greatly. Some individuals may experience progressive hearing loss, while others may have stable hearing levels. Regular monitoring and follow-up with a healthcare provider is important.
