Enlarged Vestibular Aqueduct

Enlarged Vestibular Aqueduct (EVA): Causes, Symptoms, and Effects

Enlarged Vestibular Aqueduct (EVA) is a condition characterized by an abnormally large vestibular aqueduct, a small bony canal that connects the inner ear’s endolymphatic space to the brain. This condition can lead to hearing loss and recurrent vertigo. Hearing impairment may start mildly but progressively worsens over time. Patients often experience multiple episodes of vertigo in a single day, making balance and daily activities challenging.

Causes of Enlarged Vestibular Aqueduct

EVA is often an inherited inner ear disorder. If a close family member has experienced this condition, there is a higher likelihood of developing it. Another potential cause includes viral infections, which can contribute to inner ear abnormalities.

Symptoms of Enlarged Vestibular Aqueduct

The common symptoms of EVA include:

• Progressive Sensorineural Hearing Loss (worsening over time)
• Recurring Vertigo Attacks (dizziness episodes throughout the day)
• Balance Problems (difficulty maintaining stability)
• Tinnitus (ringing or buzzing sounds in the ears)

If you experience frequent vertigo, hearing loss, or balance issues, it is essential to consult an ENT specialist for an early diagnosis and management plan.
