To observe the clinical effects of posterior percutaneous full-endoscopic cervical foraminotomy in patients with osseous foraminal stenosis. ⋯ Posterior percutaneous full-endoscopic cervical foraminotomy can accomplish full nerve root decompression and is a safe, feasible procedure. Therefore, it can be a treatment option for patients with osseous foraminal stenosis.

Comparative Study
Asleep robot-assisted surgery for the implantation of subthalamic electrodes provides the same clinical improvement and therapeutic window as awake surgery.
To study the impact of not performing awake clinical evaluation during the robot-assisted implantation of subthalamic nucleus deep brain stimulation (STN-DBS) electrodes on the stimulation parameters and clinical outcomes in patients with Parkinson disease (PD). ⋯ Asleep, robot-assisted implantation of STN-DBS electrodes (with accurate identification of the STN and positioning of the DBS lead) produced the same motor results and TW as awake surgery.

To report the initial and long-term remission rates and related factors, secondary treatments, and outcomes of a series of patients with Cushing disease (CD). ⋯ Life-long follow-up for patients with CD seems essential. Undetectable tumors on MRI before TSS and high Ki-67 immunopositivity were found as risk factors for tumor recurrence.

Spontaneous intraparenchymal hemorrhage (IPH) is a common neurosurgical emergency, with hemorrhage size and expansion associated with poor clinical outcomes. In this study, radiologic risk factors and specific IPH volume thresholds were calculated to identify heightened risk of neurologic deterioration and mortality. ⋯ Volume and growth of IPH are significant predictors of neurologic deterioration and death. An initial volume over 32 mL is associated with increased mortality risk, whereas risk of neurologic deterioration appears to peak at a smaller volume of 18 mL. Any measurable IPH expansion suggests elevated risk of deterioration and mortality.

To evaluate accuracy of a computed tomography (CT)-guided frameless stereotactic drilling and catheter system. ⋯ Highly accurate catheter placement is achievable using this novel flexible catheter and bone anchor system placed via frameless stereotaxy, with an average deviation between planned and actual target point of 1.60 mm ± 0.98 (1.40 mm, 0.40-4.00 mm).
