Recent studies highlighted how exoscopes may be employed to approach the lateral skull base. The use of exoscope-assisted procedures to repair middle cranial fossa (MCF) defects has not been fully explored. The surgical microscope in the same circumstances has been associated with relevant limitations, such as its physical obstruction, among others. The aim of this study was to present a proof of concept of exoscope-assisted surgery for MCF defects. ⋯ The exoscope allows adequate exposure of the MCF floor with identification and preservation of key anatomical structures. The exoscope represents a valuable alternative to the microscope in reconstruction of MCF defects, offering high-quality magnification and proven maneuverability.

To compare different survival prognosis scores among patients operated on for spinal metastasis from lung cancer. ⋯ The revised Tokuhashi score seemed to be the most accurate scoring system for assessing survival prognosis in patients operated on for spinal metastasis from lung cancer. Newer scores including biological parameters did not add further precision among this specific population.

Private insurers use the calendar deductible system, placing pressure on patients and medical personnel to perform medical services before the end of the year to maximize patient savings. The impact of the deductible calendar on patient-reported outcomes (PROs) after spine surgery is poorly understood. The objective of our study was to investigate if patients undergoing surgery in December had different PROs and demographics compared with all other months. ⋯ Patients undergoing elective spine surgery in December were more likely to have private insurance and be employed. PROs for ACDF and lumbar fusions were not affected by surgical timing (December yes/no). Other spinal procedures directed at more chronic diseases might be more susceptible to external influence of insurance deductibles.

Statins have been reported to reduce the rates of recurrence and improve the resolution of chronic subdural hematomas (cSDHs) treated surgically or conservatively. No studies have investigated the effect of statins in patients treated with middle meningeal artery embolization. ⋯ Patients treated with middle meningeal artery embolization alone who were on statin therapy had no differences in cSDH resolution or recurrence compared to those who were not on statin therapy. It is possible that the anti-inflammatory effects of statins may not be relevant when supply to the dura is interrupted by treatment with embolization.

Operative treatment of adolescent idiopathic scoliosis (AIS) with posterior spinal fusion aims for three-dimensional correction of coronal curve and thoracic kyphosis. Our aim was to compare two different designs of asymmetrical rods in adolescents who underwent a posterior spinal fusion with pedicle screw instrumentation for AIS with an emphasis on thoracic kyphosis restoration. ⋯ There are no significant differences in the coronal or sagittal deformity restoration in adolescent patients who underwent a posterior spinal fusion with sagittal reinforced rods and beam-like rods for adolescent idiopathic scoliosis.
