AB  - The anatomy of the temporal bone was studied to determine the optimal shape and dimensions of a new receiver-stimulator for use in young children even less than 12 months of age. There was a need to make the receiver-stimulator electronic package smaller so that it could be placed within the mastoid cavity, and the antenna wider, for more efficient power and data transmission. The antenna needed to conform to the smaller radius of a young child's skull. Anatomic dissections were carried out on skulls of children from 3 to 11 months of age to establish the variations in dimensions relevant for implantation. Prototype implant designs were evaluated in these skulls and it was found that the maximum thickness the anterior section of the receiver-stimulator should be was 5.5 mm, and its maximum width, 18 mm. It was found that a prototype electronics package with these dimensions could be fitted comfortably into the average skull of an 8-month-old child. A particular constraint was the depth of the bone over the sigmoid sinus and middle fossa. The radius of curvature of the skull of young children also required the package to be bent in its center at an angle of 160°.
