USE OF WIDEBAND ABSORBANCE MEASUREMENT TO ASSESS LARGE VESTIBULAR AQUEDUCT SYNDROME: A CASE STUDY
Journal Title: Journal of Hearing Science - Year 2017, Vol 7, Issue 1
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.

CORRELATION OF ASSR HEARING THRESHOLDS WITH ABR HEARING THRESHOLDS IN CHILDREN
Background: Hearing assessment in neonates, or in older children/teenagers with special needs, is very challenging since a pure tone audiogram is not possible due to lack of co-operation and click-ABRs are not frequency...
A FAST, “ZERO SYNAPSE” ACOUSTIC REFLEX: MIDDLE EAR MUSCLES PHYSICALLY SENSE EARDRUM VIBRATION
The middle ear muscles may be inconspicuous, but they are special. Silently standing guard at the entrance to the inner ear, their role is to spring into action whenever sound input rises, protecting the highly sensitive...

CORTICAL AUDITORY EVOKED POTENTIALS IN TWO PRELINGUALLY DEAFENED ADULTS
Background: It has been reported that in prelingually deafened adults there is maturation of the late latency response (LLR) after rehabilitation using cochlear implants. Other evidence suggests that the auditory system,...
EFFECT OF VISUAL ATTENTION ON CONTRALATERAL SUPPRESSION OF ACOUSTIC REFLEXES
Background: Cortical functions such as attention can affect the functioning of the medial efferent auditory system. This study attempts to determine the effect of visual attention on contralateral suppression of acoustic...
