16th ANNUAL EARLY HEARING DETECTION & INTERVENTION MEETING
February 26-28, 2017 • Atlanta, GA
2/28/2017 | 9:40 AM - 10:10 AM | Two Part Re-Screening Proposed to Better Triage Patients | Hanover D
The goal for any newborn hearing screening protocol is to have a high level of sensitivity and specificity to hearing loss. Here, the author proposes that using a two-part hearing re-screen can add a diagnostic element to this stage of screening, which may reduce the time between re-screen and diagnosis by more accurately triaging each infant. Brashears et. al. (EHDI 2013) presented Nemours data on 375 infants which showed the sensitivity of distortion product otoacoustic emissions (DPAOE) to middle ear effusion was 80% with a specificity of 40%. The sensitivity of Automatic Auditory Brainstem Response (AABR) to permanent hearing loss was 92% with a specificity of 93%. We propose that a two-part hearing screening using AABR and DPOAE together can help practitioners determine which infants need an Audiology / ENT follow up verses Audiology only. Middle ear effusion is one of the most common reasons for a delay in the diagnosis of permanent hearing impairment. Early identification of infants at risk for chronic otitis media can lead to better speech and language outcomes for a great number of babies. In addition, the use of these technologies in combination can help uncover suspected Auditory Neuropathy Spectrum Disorder (ANSD) early on. The diagnosis of ANSD requires the use of a diagnostic ABR using at least one rarefaction and one condensation polarity click. The differential diagnosis and management considerations for ANSD, which is responsible for 10-15% of permanent hearing losses, will also be discussed.
- Attendees will be able to list 3 reason to do OAE and AABR for the re-screen
- Attendees will be able to state when to suspect Auditory Neuropathy based on a re-screening result
- Attendees will be able to state when to suspect otitis media based on a re-screen result
