Summary of pediatric cochlear implant (CI) recipients' hearing history.
| Variable | Count | |
|---|---|---|
| Etiology | ||
| Genetic | 7 | |
| Meningitis | 6 | |
| Other/unknown | 35 | |
| Age at identification of deafness | ||
| Birth | 39 | |
| Under 12 months | 4 | |
| 13–24 months | 3 | |
| 25–36 months | 2 | |
| Age of fit of CI (months) | ||
| 8–12 | 1 | |
| 13–24 | 16 | |
| 25–36 | 11 | |
| 37–76 | 20 | |
| M (SD) | Range | |
| Duration of CI use (years) | 14 (4.3) | 7–24.5 |
| Preimplant residual hearing (PTA) | 106 (11.9) | 85–118 |
Note. Preimplant residual hearing is expressed as mean unaided pure-tone average (PTA) for the frequencies 500, 1000, and 2000 Hz in dB HL. Other/unknown etiology for hearing loss includes auditory neuropathy (n = 3), large vestibular aqueduct (n = 1), Mondini malformation (n = 2), ototoxicity (n = 1), and unknown (n = 28).
