Linear relationship of word recognition scores (WRS) with age at CI operation for the subgroups of our patients based whether short (<10 years) or intermediate (10–19 years) or long (>20 years) duration of deafness (DoD) and whether short-term (<2 years) or long-term (>5 years) preoperative use of hearing aids. (A) Patients with short DoD (regardless of short-term or long-term hearing aid use) and those with intermediate DoD and long-term hearing aid use showed significant correlations of age at CI with postCI WRS operation. On the other hand, patients with intermediate DoD with poor hearing aid use show no such a correlation (r = 0.3; p = 0.4), suggesting that age at CI operation is not an important outcome predictor in this subgroup. (B) Patients with long DoD regardless of short-term or long-term hearing aid use showed no correlation of age at CI operation with postCI WRS (r < 0.3; p > 0.3). Patients with long DoD and short-term hearing aid use displayed the poorest postCI WRS (mean = 32%).
