2 Otoacoustic Emissions (OAEs) Otoacoustic emissions are sounds that are produced by the cochlea (outer hair cells) and can be measured in the ear canal. When sound passing through the ear canal reaches the cochlea, the vibration stimulates thousands of tiny hair cells. This creates a byproduct that can be detected and measured: otoacoustic emissions. OAEs only occur in a normal cochlea with normal hearing sensitivity. If there is damage to the outer hair cells, which produces hearing loss, then OAEs will not be present. In general, OAEs will be present if hearing is at 30 db or better.

3 ERO SCAN Pro Why are OAEs Clinically Valuable? OAEs are widely applied in pediatric and adult patient populations for a variety of reasons. OAEs are an index of outer hair cell activity. Because of their dependence on normal cell metabolism, almost all insults to the cochlea first affect the outer hair cells. For example, vascular, noise damage or hypoxic cochlear deficits will be invariably reflected by reduced OAE amplitude. Therefore, assuming normal middle ear function, OAE abnormalities provide early and compelling evidence of cochlear (outer hair cell) dysfunction. Additional clinical advantages of OAE are: Brief test time: Usually less than a minute per ear Relatively simple technique: Little training is required Objective: Unaffected by attention, cognition, cooperation Independent of age: OAEs can even be recorded from newborn infants Ear specific: Test results for each ear Frequency specific: Information for many individual frequencies Test up to 10 frequency bands as close as 100 Hz apart Clinical Applications of OAEs Given their sensitivity to cochlear dysfunction, and the clinical advantages, it s not surprising that OAEs are useful in auditory assessment of diverse patient populations. One of the most common applications of OAEs is screening persons at risk for hearing impairment. OAE screening outcome is generally described as either Pass or Refer. A pass outcome is reported when OAEs are present ( 6 db above the noise floor) for the majority of test frequencies. Although the presence of OAEs does not always indicate normal hearing sensitivity, a pass outcome rules out serious degrees of hearing loss. A refer OAE screening outcome should be viewed as a clear risk factor for hearing loss that could affect communication. Patients who yield a refer outcome for OAE screening should be referred for diagnostic hearing assessment, and possible audiological or medical management.

4 OAE Say Hello to Tympanometry Ero Scan Pro As a non-invasive test, tympanometry can quickly and easily be performed on patients of any age, from infants to adults. The objectivity of tympanometry means the results are not dependant upon a response from the patient. Choose test to run (ie, linked OAE & Tymp) OAE PASS Result Advantages of Tympanometry: Tymp PASS Result Middle Ear evaluations Objective test method Test patients of any age Documented test results OAE REFER Result Features of Ero Scan Pro: Print to thermal paper, PDF, or 8.5 x 11 PC printer Customizable settings and protocols Optional patient management database Sequenced protocols permit a full test battery Review Result EroScan Pro Screen Shots

6 ERO SCAN Pro Reimbursement Otoacoustic emissions are reimbursable using the Current Procedural Terminology (CPT) codes. To date, health care reimbursement has varied in terms of cost per test but no problems have arisen if the appropriate codes are utilized. The most typical CPT code for OAE screening is: 92587: Evoked otoacoustic emissions; limited (single stimulus level, either transient or distortion product). This is the most typical code and would be considered a screening code or sampling of the cochlea : Comprehensive or diagnostic evaluation (comparison of transient and/or distortion product otoacoustic emissions at multiple levels and frequencies). This is for diagnostic OAE testing, or mapping of the cochlea : Tympanometry Conforms to IEC ERO SCAN is a trademark of ETYMOTIC RESEARCH, INC.
