title: New head fixation for the Riechert stereotaxic system. Technical note.
abstract: The combined use of stereotaxic and microsurgical techniques makes it possible to minimize damage to critical nervous tissue during operations in subcortical regions. The Riechert stereotaxic system has been further modified. The patient's head is fixed in the new head ring with standard Mayfield pins. The headring is connected to a standard Mayfield clamp at symmetrical bearings at 0, 90, 180, and 270 degrees, which holds the head stable in any desired position and allows unhindered access to the cranial vault and skull base.
