aJORO was identified with a mild bilateral loss by ABR testing at 1 month, bilateral mild to severe loss at 19 months, and a moderately severe to profound loss (right ear) with a severe to profound hearing loss (left ear) at 20 months of age.
No audiogram on file; hearing loss reported as “bilateral profound.”
No actual audiogram on file; hearing loss reported as “moderately severe to profound.”
Bulbous deformity on apical turns bilaterally.
