In an era of residency duty-hour restrictions, there has been a recent effort to implement simulation-based training methods in neurosurgery teaching institutions. Several surgical simulators have been developed, ranging from physical models to sophisticated virtual reality systems. To date, there is a paucity of information describing the clinical benefits of existing simulators and the assessment strategies to help implement them into neurosurgical curricula. Here, we present a systematic review of the current models of simulation and discuss the state-of-the-art and future directions for simulation in neurosurgery. ⋯ Advances in imaging and computer technology have led to the development of different simulation models to complement traditional surgical training. Sophisticated virtual reality (VR) simulators with haptic feedback and impressive imaging technology have provided novel options for training in neurosurgery. Breakthrough training simulation using 3D printing technology holds promise for future simulation practice, proving high-fidelity patient-specific models to complement residency surgical learning.

There are few papers in the literature comparing outcomes between antero-posterior and posterior-only approaches for treating thoracolumbar tuberculosis (T10–L2) in children. ⋯ Both the antero-posterior and posterior approaches can effectively heal T10–L2 vertebral tuberculosis, but the average surgical time, blood loss, complications, and hospital stay following the posterior approach are prominently less than those following the antero-posterior approach. It might be a better surgical treatment for thoracic spinal tuberculosis in children with poor health status, especially for cases in early phase of bone destruction and/or mild and moderate kyphosis.

Our center previously reported low transfusion rates for craniosynostosis surgery by two experienced neurosurgeons using standard intraoperative techniques and acceptance of low hemoglobin levels. This study evaluated whether low rates were maintained over the last 10 years and if a less experienced neurosurgeon, trained in and practicing in the same environment, could achieve similar outcomes. ⋯ In craniosynostosis surgery, reproducible, long-term low blood transfusion rates were able to be maintained at a single center by careful intraoperative technique and acceptance of low intraoperative and postoperative hemoglobin levels in hemodynamically stable patients. Furthermore, low rates were also achieved by an inexperienced neurosurgeon in the group. This suggests that these results may be achievable by other neurosurgeons, who follow a similar protocol.

Intraoperative ultrasound (iUS) is a valuable tool-inexpensive, adds minimal surgical time, and involves minimal risk. The diagnostic predictive value of iUS is not fully characterized in Pediatric Neurosurgery. Our objective is to determine if surgeon-completed iUS has good concordance with post-operative MRI in estimating extent of surgical resection (EOR) of pediatric brain tumors. ⋯ The results from this study suggest that iUS is reliable with both residual tumor (PPV-100%) and when it suggests no residual (NPV-98%) in tumors that are easily identifiable on iUS. However, tumors that were difficult to visualize on iUS were potentially excluded, and therefore, these results should not be extrapolated for all brain tumor types.

Review Case Reports
Spontaneous rapid resolution of acute subdural hematoma in children.
Spontaneous rapid resolution of acute subdural hematoma developing secondary to trauma has been reported in the literature, yet it is very rare in pediatric population. The aim of the present review is to analyze mechanisms, characteristics, and outcomes of pediatric acute subdural hematoma cases with spontaneous rapid resolution in conjunction with an exemplary case of ours. ⋯ Analysis of 12 pediatric patients revealed a mean and median ages of 6.87 and 3.9 years, respectively (range = 8 months-18 years). Causes for ASH development were fall, traffic accident, struggle, and child abuse. Main clinical presentations were with depressed sensorium, coma, stupor, drowsiness, headache, motor weakness, lethargy, and seizure. Close follow-up with conservative treatment should be mode of approach in pediatric patients with ASH, if neurological and radiological findings are favorable. However, if patients' neurological status deteriorates after admission to hospital, surgery should be conveyed with no further delay.
