ABSTRACT
There is a limited number of diagnostic procedures to verify the presence of large vestibular aqueduct syndrome (LVAS) in humans. The wideband absorbance (WBA) measurement technique is a non-invasive and objective tool for assessing the amount of sound energy absorbed by the
tympanic membrane over a wide frequency range. We suggest that WBA could be an aid for detecting LVAS in some hearing-impaired subjects.
We report use of WBA on a patient who had bilateral sensorineural hearing loss associated with LVAS and cochlear abnormalities in both ears.
