We aimed to investigate the possible predictive factors and longitudinal change in long-term surgical outcome after refractory frontal lobe epilepsy surgery. ⋯ The overall seizure outcome after surgery changed most during the first 2 years. The presence of frontal focal lesions and ictal frontal rhythm predicted favorable outcome. However, APOS was predictive of early epilepsy recurrence.

Endovascular treatment of transverse-sigmoid sinus dural arteriovenous fistulas (TSDAVFs) remains challenging because of their complex anatomic factors. The aim of our study was to evaluate the long-term efficacy and safety of endovascular treatment of TSDAVFs. ⋯ Favorable and durable outcomes were achieved with endovascular treatment of TSDAVFs. TSDAVFs with cortical venous reflux carry a high risk of hemorrhage and require curative treatment.

Gross total resection for glioblastoma (GBM) has been associated with better prognosis. However, it is not always feasible, and the threshold for the extent of resection required for better prognosis has been controversial. Therefore, we compared the survival and clinical outcomes of patients with GBM who had undergone partial resection (PR) or biopsy. ⋯ PR failed to improve survival compared with biopsy for patients with GBM. Moreover, the surgical complication rate in the PR group was greater than that in the biopsy group.

To analyze treatment of microvascular decompression using the retrosigmoid approach (RA) in primary trigeminal neuralgia and hemifacial spasm using preoperative images combined with intraoperative microscopic navigation to avoid unnecessarily opening the mastoid air cells (MACs). ⋯ Image processing and intraoperative microscopic navigation can avoid unnecessarily opening MACs and might reduce postoperative cerebrospinal leakage and scalp infection after RA craniotomy.

To evaluate the stability of multiple rod-connector construct designs using a mechanical 4-point bending testing frame. ⋯ Our data indicate that the design, number, and placement of rod connectors have a significant impact on the bending stiffness of a surgical construct. Such mechanical data may influence construct design in primary and revision surgeries of the cervical spine and cervicothoracic junction.
