Review Meta Analysis Comparative Study
Endoscopic versus microsurgical resection of colloid cysts: a systematic review and meta-analysis of 1,278 patients.
Colloid cysts of the third ventricle have been successfully treated with transcranial microsurgical approaches. However, the endoscopic approach has recently been advocated as a lesser invasive technique. We conducted a systematic review and meta-analysis of published studies to compare the outcomes between the two approaches. ⋯ Microsurgical resection of colloid cysts is associated with a higher rate of complete resection, lower rate of recurrence, and fewer reoperations than with endoscopic removal. However, the rate of morbidity is higher with microsurgery than with endoscopy.

Review Meta Analysis
Efficacy and safety of subdural drains after burr-hole evacuation of chronic subdural hematomas: systematic review and meta-analysis of randomized controlled trials.
To determine whether the use of a subdural drain after burr-hole evacuation of a chronic subdural hematoma is safe and effective in preventing recurrence and subsequent operations, and as such improving functional outcomes. ⋯ The meta-analysis demonstrates that the insertion of a subdural drain was associated with a statistically significant reduction in the risk of symptomatic recurrence and the requirement for further surgical intervention of chronic subdural hematoma after surgical evacuation. Furthermore, it was associated with statistically significant improvements in both short-term and long-term functional outcome.

Radiation safety and spine surgery: systematic review of exposure limits and methods to minimize radiation exposure.
Ionizing radiation is typically used during spine surgery for localization and guidance in instrumentation placement. Minimally invasive (MI) surgical procedures are increasingly popular and often require significantly more fluoroscopy, placing surgeons at risk for increased radiation exposure and radiation-induced complications. This study provides recommendations for minimizing risk of radiation-induced injury to spine surgeons and summarizes studies addressing radiation exposure in spine procedures. ⋯ Spine surgeons should reduce their exposure to radiation to minimize risk of potential long-term complications. Strategies include minimizing fluoroscopy use and dose, proper use of protective gear, and appropriate manipulation of fluoroscopic equipment.

To describe the technical and anatomic nuances related to endoscopic endonasal approaches (EEAs) to the paramedian skull base. ⋯ Approaches to the paramedian skull base are the most challenging and complex of all endoscopic endonasal techniques. Because of their technical complexity, it is recommended that surgeons master endoscopic endonasal anatomic approaches oriented to median structures (sagittal plane) before approaching paramedian (coronal plane) pathologies.

The anatomy of the skull base is extremely complex with an abundance of critical neurovascular bundles and their corresponding foramina as well as the insertions and origins of multiple masticatory and craniocervical muscles. These anatomic intricacies increase the difficulty of surgery within this area. ⋯ EEAs are important techniques in contemporary skull base surgery. Understanding the indications for and limitations of these approaches help to maximize outcomes.
