Cortical auditory evoked potential (CAEP) response for a child diagnosed with normal hearing in her left ear (A) and single-sided deafness in her right ear after age 5 years (B). The child received a cochlear implant (CI) in her right ear age 9.86 years. Pre-CI, the child demonstrates an age-appropriate CAEP response with normal morphology and a P1 response falling within normal limits in the child’s normal hearing ear (A), and a borderline delayed P1 response marked by immature morphology for the child’s age in her deaf ear (B). The developmental trajectory of the child’s SSD ear following CI shows a decrease in P1 latency within 3 months (C2), the development of higher-order N1 and P2 CAEP components within 8 months (C3), and the emergence of an age-appropriate CAEP response with normal P1 latency and morphology within 14 months after CI (C4).
