How are enlarged vestibular aqueducts diagnosed?
No treatment has proven effective in reducing the hearing loss associated with EVA or in slowing its progression. Although some otolaryngologists recommend steroids to treat sudden sensorineural hearing loss, there are no scientific studies to show that this treatment is effective or ineffective when an individual also has EVA. In addition, surgery to either drain liquid out of the endolymphatic sac and duct or to remove the endolymphatic sac and duct is not only ineffective in treating EVA, it can be harmful. Research has shown conclusively that these surgeries can destroy hearing. To reduce the likelihood of progression of hearing loss, individuals with enlarged vestibular aqueducts should avoid contact sports that might lead to head injury; wear head protection when engaged in activities that might lead to head injury (such as bicycle riding or skiing); and avoid situations that can lead to barotrauma (extreme, rapid changes in pressure), such as scuba diving or hyperbaric oxygen tr
