The audiogram demonstrates a right conductive hearing loss seen by the difference in hearing levels between the red triangles and the black brackets. The left ear hearing levels shown by the blue line are normal. This child demonstrated good function at home and in preschool and did not require intervention at this point.

Audiogram of a 5-year-old girl with right unilateral external auditory canal atresia (EACA) is shown. The audiogram demonstrates a right conductive hearing loss seen by the difference in hearing levels between the red triangles and the black brackets. The left ear hearing levels shown by the blue line are normal. This child demonstrated good function at home and in preschool and did not require intervention at this point.

Her functioning in kindergarten continues to be excellent, and she has noticed hearing improvement at home. Her physical examination shows a pinpoint opening at the external auditory canal (EAC) now, and this audiogram confirms improved hearing in the right ear compared to the prior audiogram in Image 2. Her right conductive hearing loss is shown by the distance between the black brackets and the red triangles.
