The procedure is performed with a portable handheld screening unit.
A small prove is placed in the child's ear canal.
This probe delivers a low-volume sound stimulus into the ear.
The cochlear responds by producing an otoacoustic emission,
sometimes described as an echo, that travels back through the
middle ear to the ear canal and is analyzed by the screening unit.
In approximately 30 seconds, the result is displayed on the
screening unit as a "pass" or "refer."
Children not passing the OAE screening are assessed for
Middle ear effusion, treated as needed, then rescreened or
referred to a pediatric audiologist for further evaluation.
