Conductive Hearing Loss Diagnosis in Newborn Hearing Screening Follow-up Using Wideband Immittance
Newborn hearing screening (NHS) referrals may be caused by transient or permanent 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. Wideband acoustic immittance (WAI)provides a more thorough analysis of middle ear function than standard tympanometry by testing across a broad frequency range using click stimuli rather than pure tones. Goals: This study was designed to assess whether WAI improves accuracy of detecting transient and permanent conductive hearing loss. Methods: Infants were enrolled from well-baby and NICU nurseries in a clinical trial. 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 WAI at birth and follow-up (1 and 9 months). Infants who attended a follow-up diagnostic evaluation were also assessed with toneburst air and bone conduction ABR, DPOAE and the wideband acoustic test battery. Results: 41 cases of conductive hearing loss were diagnosed, including several cases of permanent conductive hearing loss. The wideband test battery effectively diagnosed infants who referred on Stage I or II screening due to temporary middle ear problems, or who had permanent conductive hearing loss, as determined by the diagnostic ABR. Results will be discussed relative to screening and diagnostic applications of the WB test.
