Timpanometría de alta frecuencia (1.000 Hz) en lactantes y su comparación con otoemisiones acústicas, otomicroscopia y timpanometría de 226 Hz

The joint use of otomicroscopy, transient otoacoustic emissions and 226 Hz and 1 kHz tympanometry, has allowed us to diagnose otitis media with effusion in young infants more accurately than each test separately. We recommend initial use of 1 kHz tympanometry, at least in children younger than 7 months, but in the presence of hearing loss or an unclear result, 226 Hz tympanometry is a good diagnostic complement.
