Community Hospital was the first hospital in Northwest Indiana to provide comprehensive vestibular assessment for patients experiencing dizziness or vertigo. Audiology Services is also known as the leading pediatric audiology department in Northwest Indiana, performing screenings on newborns in the Regular Care Nursery, Special Care Nursery and Neonatal Intensive Care Unit - as hearing loss is one of the most common birth defects with six out of every 1,000 babies born with hearing loss.
- Our office is equipped to perform Videonystagmography (VNG) which assesses the balance center portion of the inner ear. VNG is a complete diagnostic system for recording, analyzing and reporting involuntary eye movements, called nystagmus, using video imaging technology. Hi-tech video goggles with infrared cameras are worn while you look or lie in different positions.
- Auditory Brainstem Response (ABR) testing is also available to check the nerve pathway beyond the inner ear. ABR audiometry is a safe and painless test of the hearing pathway and brainstem function in response to sound or (click) stimuli.
- Tympanometry or middle ear testing is done by inserting a probe into the ear which emits a tone with a certain amount of sound energy. The probe measures how much sound energy bounces back off the eardrum, rather than being transmitted to the middle ear. The more energy that is returned to the probe, the greater the blockage of the middle ear.
- Otoacoustic Emissions (OAEs) are also performed on infants as mandated by the Newborn Screening program for the State of Indiana. An OAE measures an acoustic response that is produced by the inner ear (cochlea), which bounces back out of the ear in response to a sound stimulus. The test is performed by placing a small probe that contains a microphone and speaker into the infant's ear. As the infant rests quietly, sounds are generated in the probe and responses that come back from the cochlea are recorded. Once the cochlea processes the sound, an electrical stimulus is sent to the brainstem. In addition, there is a second and separate sound that does not travel up the nerve, but comes back out into the infant's ear canal. This "byproduct" is the otoacoustic emission. The emission is then recorded with the microphone probe and depicted on a computer screen.
