Audiology Services
Diagnostics and Treatment
For the convenience of our patients, Shohet Ear Associates offers all diagnostic
services on-site. These include:
- Hearing Tests - measure how well a person hears
- Tympanometry - evaluates the status of the middle ear
space and eardrum
- Otoacoustic emissions (OAE) - are an objective measure
of the inner ear's sensory cell function
- Electrocochleography (ECOG) - Asseses inner ear function
to determine if cochlear hydrops is present
- Auditory brainstem response (ABR) - A useful clinical
tool to help detect, localize and monitor auditory and neurotologic deficits
as well as estimate hearing in difficult to test patients
- Electronystagmometry (ENG) - tests balance function
- Electroneurography (ENOG) - examines facial nerve function
- Vestibular Autorotational Test (VAT)- Assesses the balance
function
In addition, our skilled audiologists offer a complete array of diagnostic
and treatment services, including:
Auditory Brainstem Response (ABR) or Brainstem
Auditory-Evoked Response (BAER)
Auditory Brainstem Response measures the level of hearing in the middle
and inner ear, and is useful when more conventional hearing tests cannot
be used. It evaluates brain wave activity in the auditory centers of
the brain when a series of clicks is presented to each ear. ABR can be used
as a screening
tool for newborns who are at risk for hearing loss, patients who may
already have hearing loss, patients with Ménière's disease or similar disorders,
and
difficult-to-evaluate patients such those who are mentally retarded,
autistic, or developmentally delayed. ( TOP )
Electronystagmography (ENG)
Electronystagmography (ENG) is used to evaluate patients with dizziness, vertigo,
or balance dysfunction. ENG includes the use of electro-oculography to record
eye movements. The vestibular system monitors the position and movements of
the head in order to stabilize retinal images. ENG provides an objective assessment
of the oculomotor and vestibular systems. ENG consists of three parts: oculomotor
evaluation, positioning/positional testing, and caloric stimulation of the
vestibular system.
The subtests of an ENG evaluate the oculomotor and vestibular systems. Comparison
of the results obtained assists in determining the source of dizziness
or unsteadiness. This includes assessing the system responsible for rapid eye
movements and refixation, the presence, absence, and ability of fixation of
spontaneous nystagmus, the ability of the oculomotor system to track a target
within the visual field, the presence or absence of nystagmus associated with
benign paroxysmal positional vertigo (BPPV), the presence or absence of nystagmus
in various body positions, and if a side of lesion can be inferred from results
of caloric irrigation.
The test requires about sixty (60) minutes to complete. Although some
people experience some dizziness during the test, the dizziness is usually
of short
duration. ( TOP )
