Diagnostic Audiology Services
Our expert physicians and audiologists coordinate treatment plans to ensure you receive excellent management for your hearing problems. You’ll be able to get all of your hearing healthcare services in one location instead of traveling between offices or specialties. Our audiology services include the following:
Diagnostic Audiological Evaluation:
Battery of tests used to assess the type and severity of the hearing loss as well as the health and condition of the auditory pathway and surrounding anatomy. This evaluation reveals whether a hearing loss is the result of a treatable medical condition that warrants medical or surgical management or if the hearing loss is the result of a non-medical condition such as noise exposure or aging. Procedures include otoscopy, middle ear analysis, acoustic reflex testing, air and bone conduction pure tone threshold testing, word recognition/speech testing and otoacoustic emissions.
Battery of tests that measure information about the eardrum (tympanic membrane), the status of the middle ear and the functioning of the acoustic reflex. A puff of air is delivered into the ear to measure how the eardrum moves in response to change in air pressure. The results are used to determine the presence of middle-ear fluid, ear drum perforations, and other middle ear disorders.
Otoacoustic Emissions (OAE):
The OAE test is used to determine cochlear (inner ear) status and is performed by placing an earphone in the patient’s ear canal and introducing various sounds. It requires no behavioral response from the patient so it can be done on patients of all ages, and even a sleeping or comatose patient. The results can be used to: screen hearing in neonates, infants, or difficult to test individuals with developmental disabilities; differentiate between the sensory and neural components of sensorineural hearing loss; estimate hearing sensitivity within a limited range, and; test for functional or feigned hearing loss.
Series of tests to evaluate the balance system. When the head is in motion, the inner-ear balance organs send signals to the eye muscles to keep vision in focus making eye movements a non invasive way to evaluate the balance system. Specialized video goggles with infrared cameras are used to record and measure eye movements as patients follow a moving light with their eyes and as they sit and lie in different positions. Each ear canal is stimulated by warm and cool water (caloric test) irrigations. The water causes a temperature change in the inner ear fluids which creates characteristic eye movements (called nystagmus) that can be measured and compared for each ear as well as to a large group of normative data. The information obtained from the VNG helps diagnose patients’ complaints of dizziness, vertigo and imbalance
BAHA (Bone Anchored Hearing Aid) Evaluation and Fitting:
The BAHA is a partially implanted hearing system for patients who cannot be helped by traditional hearing aids. Candidates for the BAHA include people who lack an outer ear or ear canal opening, people who have chronic middle ear infections, chronically draining ears, people who have a conductive hearing loss that cannot be treated medically, and patients who are deaf in one ear with normal or near normal hearing in the other ear. A surgical procedure is performed to place a small titanium implant in the skull behind the ear. After healing, a sound processor is attached to the implant. The sound is delivered to the inner ear through bone conduction, bypassing the outer and middle ear and stimulating the inner ear. In patients with single sided deafness the sound is delivered directly to the good ear via bone conduction and eventually the brain is able to distinguish between sound that comes from the deaf side via the BAHA and sound that comes directly from the hearing ear. To learn more about the BAHA, visit the Hearing Health Care Support & Resource Center. If you think you may receive benefit from this type of device schedule an appointment with one of our ENT physicians and the Audiologist. They will work together to determine if this system is appropriate for you.
