In addition, the provider will perform otoscopic screening as part of the physical exam. Tympanometry is also an optional tool. Otoacoustic Emissions (OAE) Technology Otoacoustic emissions (OAE) screening is a hearing test that uses a small probe inserted into the external ear canal to introduce a sound stimulus (series of beeps) and measures the response sound, like an echo, emitted by the inner ear (cochlea) of a normal hearing person. The cochlea of a person with hearing loss greater than 25-30 dB does not emit a sound in response to a sound stimulus. As of July 2010, OAEs are not part of the Minnesota Department of Health’s (MDH) hearing screening procedures. However, many studies have shown that screening children 0-3 years of age may be beneficial with OAEs. 14 The OAE technology is very good for children who are unable to respond to a sound by raising their hand or dropping a toy into a bucket to indicate response to the stimulus. It is not recommended for children over age 3 years who are developmentally able to perform pure tone audiometry, either by the play or hand raising method. However, OAE technology may not be able to detect a mild hearing loss (defined as a 20dB to a 40dB loss), which can impact a child’s performance in school. One study shows that 37% of children with mild hearing loss fail at least one grade. 6 6
Ages/Grades: 1 month* to 3 years SCREENING PROCEDURES HEARING HISTORY Purpose: To determine if medical factors exist to put the child at risk for hearing loss Description: A review of the history questions with the parent or caregiver Equipment: Forms: See JCIH Risk Factors and Mommy Can You Hear me? http://www.health.state.mn.us/divs/fh/mch/unhs/resources/brochures/chec klist-english.html Facilities: Comfortable, private interview area Procedure: Question the parent/caregiver about the child's hearing history. Pass: No positive response to hearing history Rescreen/ Refer: Refer to the Joint Committee on Infant Hearing Position Statement (2007) for a list of hearing loss risk indicators (page 13). Children with one or more risk factors should have ongoing hearing screening and at least one diagnostic audiology assessment by 24 to 30 months of age. 1516 *For the 0-1 month time frame: The C&TC periodicity schedule indicates O/S. At this visit (or the first C&TC visit if this one is not scheduled), the parent should be asked if the infant had newborn screening in the nursery and if so, did the infant pass newborn screening. If the answer is no to either of these questions, the infant should be referred for OAE and/or ABR screening. 7
