Review Meta Analysis
The role of adjuvant radiotherapy after gross total resection of atypical meningiomas.
Atypical meningiomas (AMs) frequently recur after gross total resection (GTR). ⋯ Postoperative RT for AMs may decrease risk for relapse of disease and improve local control, although most tumors are salvageable with surgery or radiation. Although the data suggest little or no impact of postoperative RT on survival, further investigation regarding the long-term efficacy and toxicity of radiation is warranted.

Review Meta Analysis Comparative Study
Arachnolysis or cerebrospinal fluid diversion for adult-onset syringomyelia? A Systematic review of the literature.
To identify surgical practice patterns in the literature for nonpediatric syringomyelia by systematic review and to determine the following: 1) What is the best clinical practice of cerebrospinal fluid (CSF) diversion to maximize clinical improvement or to achieve the lowest recurrence rate? 2) Does arachnolysis, rather than CSF diversion, lead to prolonged times to clinical recurrence? ⋯ With postinfectious and posttraumatic etiologies, arachnolysis was the only surgical treatment to have a statistically significant effect on decreasing recurrence rates. More prospective, randomized, controlled studies are required to reach a clear consensus.

Multicenter Study
Predictors of severe complications in intracranial meningioma surgery: a population-based multicenter study.
To investigate predictors of complications after intracranial meningioma resection using a standardized reporting system for adverse events. ⋯ Severe complications after meningioma resection are more encountered often in elderly patients (>70 years old), dependent patients (Karnofsky performance scale score <70), and patients who underwent longer lasting surgery (>4 hours). Patient selection, including careful consideration of the individual risk-benefit ratio, is important in improving the safety of intracranial meningioma resection.

Using current surgical methods, cranioplasty is associated with a high complication rate. We analyzed if there are preexisting medical conditions associated with complications and compared the effect of different implant materials on the degree of complications. ⋯ Based on these results, synthetic materials for cranial bone defect reconstruction exhibit more promising outcomes compared with autograft. There were differences in survival rates among synthetic materials.
