Abstract BACKGROUND Supplementary motor area (SMA) syndrome occurs after surgery involving the SMA and is characterized by contralateral hemiparesis with or without speech impairment (dependent on involvement of the dominant SMA), which is transient and characteristically resolves over the course of weeks to months. Recurrent SMA syndrome after repeat craniotomy has not been previously described. OBJECTIVE To describe the presentation and clinical course of patients who developed recurrent SMA syndrome after redo resection of tumors involving the SMA. METHODS We performed a retrospective review of 15 patients who underwent repeated resection of low-grade glioma from the superior and middle frontal gyrus. Of these patients, we identified 6 cases of recurrent SMA syndrome. RESULTS Six patients had a documented SMA syndrome occurring after initial and subsequent resection of tumor in proximity to the SMA. Intraoperative localization of eloquent motor and language cortex was achieved in each patient by using a combination of somatosensory evoked potentials and electrocortical stimulation mapping. Location of tumor and extent of resection was examined with magnetic resonance imaging. CONCLUSION This series demonstrates that recurrent SMA syndrome occurs in patients undergoing repeat resection of tumors involving the SMA. The presence of recurrent SMA syndrome provides support for reorganization of SMA function to adjacent ipsilateral cortex after resection. Patients with recurrent neoplasms of the SMA should be counseled on the possibility of recurrent SMA syndrome.

Abstract Three-dimensional force perception is critically important in the enhancement of human force perception to minimize brain injuries resulting from excessive forces applied by surgical instruments in robot-assisted brain tumor resection. And surgeons are not responsive enough to interpret tool-tissue interaction forces. In previous studies, various force measurement techniques have been published. In neurosurgical scenarios, there are still some drawbacks to these presented approaches to forces perception. Because of the narrow, and slim configuration of bipolar forceps, three-dimensional contact forces on forceps tips is not easy to be traced in real-time. Five fundamental acts of handling bipolar forceps are poking, opposing, pressing, opening, and closing. The first three acts independently correspond to the axial force of z, x, y. So, in this paper, typical interactions between bipolar forceps and brain tissues have been analyzed. A three-dimensional force perception technique to collect force data on bipolar forceps tips by installing three Fiber Bragg Grating Sensors (FBGs) on each prong of bipolar forceps in real-time is proposed. Experiments using a tele-neurosurgical robot were performed on an in-vitro pig brain. In the experiments, three-dimensional forces were tracked in real-time. It is possible to experience forces at a minimum of 0.01 N. The three-dimensional force perception range is 0-4 N. The calibrating resolution on x, y, and z, is 0.01, 0.03, 0.1 N, separately. According to our observation, the measurement accuracy precision is over 95%.
