An evaluation of newborn hearing screening brochures and parental understanding of screening result terminology.

OBJECTIVE: To assess the suitability of newborn hearing screening brochures by evaluating current state-level brochures and pregnant people's understanding of screening result terminology. DESIGN: In Study 1, state-level brochures were evaluated based on readability, design, picture appropriateness, and use of the word "refer." In Study 2, pregnant people completed a questionnaire that queried their understanding of and expected anxiety about three newborn hearing screening outcomes ("refer," "did not pass," and "pass"). STUDY SAMPLE: In Study 1, 59 newborn hearing screening brochures were analysed. In Study 2, 43 pregnant people completed surveys during a prenatal appointment. RESULTS: Most of the brochures were found deficient on at least one element. Thirty percent of brochures used the word "refer" to indicate a hearing screening failure; yet, fewer than half of participants understood its meaning. Ratings of expected anxiety were highest in response to the term "did not pass." CONCLUSIONS: Based on four study criteria of brochure suitability, 88% of available state-level newborn hearing screening brochures should be modified to make them readily understandable by a broad educational demographic. Discretion in use of the term "refer" should be made when indicating screening results, because the term is not readily understood.

Correlation of air-bone gap and size of Enlarged Vestibular Aqueduct in children.

OBJECTIVE: Enlarged vestibular aqueduct (EVA) is an inner ear malformation that represents an important cause of pediatric hearing loss. While certain elements in the history or audiogram may suggest EVA, it is most often diagnosed using computed tomography (CT). The present investigation was conducted to determine if the size of the audiometric air-bone gap (ABG) is correlated with the size of the vestibular aqueduct in the pediatric population using three vestibular aqueduct measurements. These included the fundus, midpoint, and porous widths of the vestibular aqueduct. STUDY DESIGN: This is a retrospective cohort study. SETTING: This study took place at a tertiary care referral center. PATIENTS: Fifty-five children (33 female; 22 male) with a confirmed diagnosis of unilateral or bilateral EVA as determined by prior imaging of the inner ear were included in the study. MAIN OUTCOME MEASURES: Associations of EVA measurements with ABGs at 0.5 and 1 kHz were evaluated using Pearson correlation coefficients. RESULTS: All of the correlation coefficients were positive, indicating that as EVA measurements increased so did the ABG. Only the correlation between fundus width and ABG at 1 kHz was not statistically significant. CONCLUSIONS: ABGs measured during audiometric testing correlate with the size of the EVA and ABGs can be clinical predictors of the severity of the bony abnormality. These data support the third window theory of conductive hearing loss in pediatric EVA.
