Conductive hearing loss assessment in children with otitis media with effusion. A comparison of pure tone and BERA results.
A comparison between pure-tone audiometry and brainstem electric response audiometry was made in 25 children with a conductive hearing loss due to otitis media with effusion. Pure-tone audiometry, including bone and air-conduction thresholds, was recorded using standard procedures. BERA was used to construct a latency-intensity function and from this the conductive hearing loss could be estimated. For all frequencies except for 2000 Hz a good correlation was found between the conductive loss in the pure-tone audiogram and the conductive loss as estimated by BERA. The moderate correlation for 2000 Hz is due to a 'Carhart'-notch-like phenomenon in the pure-tone audiogram.
