Figure 3. Audiograms of patients III-2 and IV-2. (A) Audiogram of patient III-2 at age of 5 years. (B) Audiogram of patient III-2 at age of 8 years. (C) Audiogram of patient IV-2 at age 5 years. Bilateral air–bone gaps are recognized, especially at lower frequencies in patient III-2. Circle or × indicate unmasked examination of air conduction for the right or left ear, triangle or square indicate masked examination of air conduction for right or left ear, < or > indicate unmasked bone conduction for right or left ear, [ or ] indicate masked bone conduction for right or left ear.
