Objective:

This study is designed to test the hypothesis that preservation of residual hearing in a pediatric population is possible using standard electrode arrays with full-length insertions. Surgical technique during implantation also is described.

Study Design:

Retrospective review of patient medical records.

Setting:

Academic tertiary care center.

Patients:

Thirty-one severely to profoundly hearing impaired pediatric patients with some residual hearing precochlear implantation.

Intervention:

Cochlear implantation using a modified" soft surgery" protocol.

Main Outcome Measures:

Preimplant and postimplant pure tone thresholds and pure-tone average were calculated from unaided preoperative and postoperative audiograms from 250, 500, and 1,000 Hz. Hearing preservation rates were determined to be complete (loss of≤ 10 dB), moderate (loss of 11-20 dB), marginal (loss of 21-40 dB), or none (loss of> 40 dB or no …
