Forty\u2010five children with hearing loss that resulted from bacterial meningitis were implanted from 1991 to 2006.

Six patients (37.5%) required circummodiolar drill\u2010outs, and one patient (6.25%) underwent placement of a double array cochlear implant. The nine remaining patients (56%) with cochlear obstruction required removal of fibrous tissue or drilling of the inferior basal turn, but did not require manipulation of the ascending basal turn to achieve full electrode insertion. The sensitivity, specificity, and positive and negative predictive value of MRI predicting intraoperative cochlear obstruction with 95 percent confidence intervals was 94.1 percent (71\u201399), 87.5
