The presence of such bone growth was thought previously to require the selection of a short electrode implant.

A series of 37 patients who underwent cochlear implantation in a four-year period were reviewed. Ten of 37 patients were noted to have cochlear neo-ossification at surgery; in seven of ten patients, ossification was predicted preoperatively by a computed tomographic scan.
