Abstract
In this chapter, the basic techniques involved in the midline suboccipital approach and its variations are explained, focusing on intracranial lesion exposure, patient positioning, and bony opening sites. The midline suboccipital approach varies from case to case: the range of bony openings is altered up and down or left and right, depending on the lesion location. To approach lesions in the fourth ventricle and cerebellar hemisphere accurately, exposure of the vermian and/or cerebellar hemispheric surfaces must be considered when selecting patient positioning and bony opening site [13, 15]. Furthermore, preoperative interpretation of lesion location is vital [6, 10].
