Cochlear implantation in children: the problem of head growth.

Successful implantation in children requires that provision be made for later head growth. The timing and magnitude of this growth was determined by measurements made from high-resolution computerized tomographic images of developing temporal bones. The temporal bone scans of 103 children of varying ages were studied. The development of the petrous and squamous portion of the temporal bone was at its greatest in the first 2 years of life. The order of magnitude of growth varied with the different axes measured.
