Ask the Experts | Medical & Surgical | Hearing & Hearing Loss | Large Vestibular Aqueduct Syndrome Large Vestibular Aqueduct Syndrome Noel Cohen, MD February 18, 2002 Print Question What are the most recent advances in the management of Large Vestibular Aqueduct Syndrome (LVAS)? What is the audiologist's role? Answer There still is no effective treatment for the LVAS. Avoiding unnecessary cranial trauma and barometric pressure changes may help to delay or avoid sudden changes in hearing, but there is no good data on this. I do not believe that any medical treatment (e.g. with diuretics or steroids) helps, and surgical attacks on the endolymphatic sac have resulted in further loss. The difficulty for the audiologist is to provide flexible amplification to deal with the fluctuating hear loss, and to think of a cochlear implant in the long term.

This discussion includes factors that may affect hearing preservation with traditional cochlear implant devices as well as a discussion of research findings with hybrid/EAS devices.Editor's note 10/7/11: There have been rapid changes in the field of cochlear implantation thanks to ongoing advances in research and technology. Just since this article has been published, there are some very recent developments in EAS research at the University of Iowa. In the last three months, they have been given FDA approval to conduct two feasibility trials to study preservation of hearing with Nucleus hybrid cochlear implants in those with severe hearing loss and will be implanting children between the ages of 5 and 15 years of age. This new information about the Iowa-sponsored feasibility trials contradicts two points within questions 15 to 18 of the article: Adults with greater hearing impairment than those in the clinical trial described in the article are eligible for implantation with a Nucleus Hybrid L24 implant through the Iowa-sponsored feasibility trial, and the S12 and L24 devices are available to children through the feasibility study at the University of Iowa. Please keep this is mind as you read the article. As new advances are made in this exciting area of research and practice, we will try our best to keep you informed! Course Details
