Detection of Middle Ear Dysfunction Using Wideband Acoustic Tests in Newborn Hearing Screening and Diagnostic Follow-Up
Background: More than 80% of newborn hearing screening (NHS) referrals are due to transient middle ear conditions. A major challenge in achieving diagnosis by age 3 months is determining if the referral is due to temporary or permanent hearing loss. A wideband (WB) acoustic test has the potential to improve hearing screening and diagnosis of middle-ear and cochlear dysfunction in newborns referred from hearing screening.
Goals: This study was designed to assess whether a WB test battery improves accuracy of distinguishing between CHL and SNHL, compared to gold standard diagnostic air and bone conduction ABR.
Methods: Infants (N=691) were enrolled from well-baby (N=545) and NICU nurseries (N=146). Well newborns were tested with the newborn hearing screening protocol of Stage I screening with transient evoked otoacoustic emission (TEOAE) and Stage II screening with automated auditory brainstem response (AABR) if TEOAE was referred. NICU newborns were tested with TEOAE or DPOAE and automated or diagnostic ABR. All infants were tested with the wideband acoustic test battery. Infants who attended a follow-up diagnostic evaluation (N=393) were assessed with toneburst air and bone conduction ABR, DPOAE and the wideband acoustic test battery.
Results: The study enrolled infants who referred on Stage I or II, and a similar sample of infants who passed Stage I screening. 274 infants referred on TEOAE in one or both ears (40%), 144 infants referred on AABR in one or both ears (21%), and 272 (39%) passed initial screening with OAE. The wideband test battery effectively predicted infants who referred on Stage I or II screening due to temporary middle ear problems, or who had conductive hearing loss, as determined by the diagnostic ABR. Results will be discussed relative to screening and diagnostic applications of the WB test.
- Define how transient middle ear problems affect newborn screening.
- Discuss effectiveness of wideband immittance for diagnosis of newborn hearing referrals.
- Explain how middle ear problems affect OAE and ABR screening.
