Fig 1. Age at CI-1 and pre-implant hearing.

Fig 1

Children who were implanted at later ages (n = 15) had better residual hearing (ie. lower aided thresholds) at 250 Hz when assessed with standard audiometric testing prior to implantation (R = -0.50, p = 0.026). This relationship is was also present at 500 Hz (R = -0.50, p = 0.013), but not 1000 Hz (R = -0.28, p = 0.23), 2000 Hz (R = -0.01, p = 0.97), or 4000 Hz (R = 0.15, p = 0.57).
