ABSTRACT
OBJECTIVE: To explore the application value of real-time intraoperative ultrasound in glioma surgery. METHODS: A total of 80 cases of glioma were localized by intraoperative ultrasound, and their resection degree was evaluated postoperatively by magnetic resonance imaging (MRI). RESULTS: All gliomas were located precisely by real-time intraoperative ultrasound under the guidance of preoperative MRI. Among them, 72 cases underwent total resection, 2 cases had residual tumor on post-operative MRI. Subtotal resection was performed in 8 cases. And one of them had larger residual tumor on post-operative MRI. The accuracy rate of resection was 96.2%. There was no complication related with ultrasound. CONCLUSION: Intraoperative ultrasound may help a neurosurgeon to locate lesions, select optimal approaches, guide operative procedures and estimate the extent of resection. Because of its small, flexible and convenient features, it will be widely used in neurosurgery.

OBJECTIVE: To explore the intraoperative oculomotor nerve monitoring during skull base tumor surgery for injury avoidance. METHODS: The study was conducted from January 2006 to January 2012. Monitoring group:35 skull base tumor operations were monitored by neurophysiology (22 males and 13 females). CONTROL GROUP: 26 skull base tumor operations without intraoperative monitoring were treated with microsurgery alone (16 males and 10 females). The prognoses of different groups were evaluated. RESULTS: Monitoring group:2 cases had injury of oculomotor nerve. One of them suffered mild diplopia and recovered one months later. Another one had blepharoptosis and mydriasis, reaction to light was absent and recovered six months later. CONTROL GROUP: 6 cases had injury of oculomotor nerve. Five of 6 cases recovered six months later. And one showed no recovery after a 1-year follow-up. CONCLUSION: Intraoperative monitoring of oculomotor is essential for the protection of oculomotor nerve during skull base tumor surgery.
