Review Meta Analysis
Cranioplasty infection and resorption are associated with presence of a ventriculoperitoneal shunt: A systematic review and meta-analysis.
Following decompressive craniectomy, hydrocephalus is a common complication often necessitating placement of a ventriculoperitoneal shunt (VPS). Complications in the presence of a VPS have been reported, but a clear association has not been established. ⋯ Cranioplasty in the presence of a VPS is associated with a higher rate of overall complications, including infection and bone resorption. Performing cranioplasty and VPS placement in the same operation is associated with an increased rate of complications compared with staged procedures. Surgeons should consider staging these procedures when possible and counsel patients about these risks.

Review Meta Analysis
The Diagnostic Accuracy of Evoked Potential Monitoring Techniques during Intracranial Aneurysm Surgery for Predicting Postoperative Ischaemic Damage: A Systematic Review and Meta-analysis.
To investigate the diagnostic accuracy of various evoked potential monitoring techniques in predicting postoperative neurologic deficit in intracranial aneurysm surgery. ⋯ TcMEP and DMEP have higher diagnostic accuracy than SSEP in predicting postoperative neurologic deficit. The type of anesthetic agent, the use of neuromuscular blocking drugs, and the choice of diagnostic criteria for significant change in cerebral blood flow during aneurysm surgery affect the diagnostic accuracy of evoked potential techniques in predicting postoperative neurologic deficit.

Review Meta Analysis
Meta-analysis on safety and efficacy of microsurgical and radiosurgical treatment of trigeminal neuralgia.
Classic trigeminal neuralgia is often treated pharmacologically first. However, microvascular decompression (MVD) or radiosurgical treatment (RS) can render medication unnecessary. Objective appraisals of the 2 treatment modalities are scarce. ⋯ MVD is a valid first-line treatment option for young patients free of comorbidities. First-line RS can be advised in patients with a higher surgical risk.

For many years, the right hemisphere (RH) was considered as nondominant, especially in right-handers. In neurosurgical practice, this dogma resulted in the selection of awake procedure with language mapping only for lesions of the left dominant hemisphere. Conversely, surgery under general anesthesia (possibly with motor mapping) was usually proposed for right lesions. ⋯ These original findings, which break with the myth of a nondominant RH, may have important implications in cognitive neurosciences, by improving our knowledge of the functional connectivity of the RH, as well as for the clinical management of patients with a right lesion. In brain surgery, awake mapping should be considered more systematically in the RH. Moreover, neuropsychological examination must be achieved in a more systematic manner before and after surgery within the RH, to optimize care by predicting the likelihood of functional recovery and by elaborating specific programs of rehabilitation.

Despite the increasing awareness of scientific fraud, no attempt has been made to assess its prevalence in neurosurgery. The aim of our review was to assess the chronologic trend, reasons, research type/design, and country of origin of retracted neurosurgical publications. ⋯ Retractions of neurosurgical publications are increasing significantly, mostly because of issues of academic integrity, including duplicate publishing and plagiarism. Implementation of more transparent data-sharing repositories and thorough screening of data before manuscript submission, as well as additional educational programs for new researchers, may help mitigate these issues in the future.
