To analyze the correlation between intracranial air and electrode displacement after deep brain stimulation. Compared the accuracy of the electrodes on both sides while bilateral intracranial air. A total of 133 patients with bilateral DBS from February 2017 to February 2019 in neurosurgery department of the General Hospital of Northern Theater Command were included. A total of 266 electrodes were implanted, including 160 sides of subthalamic nucleus, 2 sides of ventromedial nucleus of thalamus and 104 sides of Globus pallidus interior. All patients underwent three-dimensional reconstruction of the head 2 hours after operation and 1 week after operation, which was fused with the preoperative surgical plan.The volume of the intracranial air is obtained by summing up the CT layer-by-layer measurements after surgery. The distance between the implanted electrode and the preoperative target on the X and Y axes in the target plane is measured.Values were expressed as means±SEM,and the test was performed. Bivariate
