The BERAphone
®
ABR transducer is optimized in size and shape for newborns up to
approximately 3 months of age. Older infants with larger ears may be difficult to test
with the BERAphone
®
. The key to an acceptable fit is to achieve contact of the ear
cushion all around its edge with no gaps between the skin and the cushion. Any gaps
can lead to a reduction in the stimulus intensity increasing test time and the chance of
a Refer outcome.
Clinical Use of the Measurement and Clinical Outcome
The easyScreen is a screening device used for audiologic evaluation and
documentation of ear and nerve disorders. In case of a positive result the patient shall
be referred for follow-up diagnostic examination. Infants who have risk factors for
hearing loss should be referred for follow-up and periodic re-screening of hearing even
if the result of the hearing screening is a Pass.
1.3 Contraindications
Contraindications to testing include recent stapedectomy or middle ear surgery, a
discharging ear, acute external auditory canal trauma, discomfort (e.g., severe otitis
externa) or occlusion of the external auditory canal. Testing should not be performed on
patients with such symptoms without a medical doctor’s approval.The BERAphone
®
is
intended for use on intact, external skin around the ears and on the scalp. It should not
be used if the skin is not intact or if the baby has a contagious dermatological condition.
