Abstract
Background: Although frameless stereotactic techniques have become indispensable in neurosurgery, navigation is of particular concern when it is applied to approach a complex, tight surgical area like the temporal bone, where virtually every millimeter is important. Theoretically, the temporal bone is an ideal location in which to employ image-guided navigation because its bony construct precludes preoperative and intraoperative shift. In this context, the feasibility of using a navigational system is determined by the system's accuracy and by the spatial characteristics of the targets.
