Severe traumatic brain injury constitutes a clinical entity with complex underlying pathophysiology. Management of patients with severe traumatic brain injury is guided by Clinical Practice Guidelines and Consensus Statements (CPG and CS). The published CPG and CS vary in quality, comprehensiveness, and clinical applicability. The value of critically assessing CPG and CS cannot be overemphasized. The aim of our study was to assess the quality of the published CPG and CS, based on the Appraisal of Guidelines for Research and Evaluation II instrument. ⋯ The purpose of our study for assessing the quality of CPG and CS was served. We present the strong and weak points of CPG and CS. Our findings support the idea of periodically updating guidelines and improving their rigor of development.

Microsurgical dissection of arachnoid cisterns requires a combination of anatomic knowledge and microsurgical skill. The latter relies on experience and microsurgical dexterity, which depend on visual identification of cisternal microvasculature. We describe a novel standardized operative sequence to allow for bloodless arachnoid dissection when cisternal anatomy is challenging. ⋯ The microcisternal drainage technique uses deliberate and strategic suction, dynamic retraction, and nuanced scissor cuts to enable precise and bloodless microdissection of adherent arachnoid cisterns. This technique combines common neurosurgical maneuvers in a novel standardized sequence to improve efficiency and safety during arachnoid dissection.

The preservation of the temporalis muscle during cranioplasty is very important for postoperative masticatory function and aesthetics. The key technique for temporalis muscle preservation is to find the surgical plane during the operation. ⋯ The technical effect is ideal, the operation is simple, and the technique is suitable for promotion.

Recent advances in intraoperative neuronavigation and cranial access devices have facilitated an increasing interest in the use of minimally invasive techniques (minimally invasive surgery) to safely treat subcortical lesions via a parafascicular approach. Newly developed expandable retractors, such as the MindsEye system further optimize such approaches. In this technical report, we describe the nuances in minimally invasive surgery parenchymal hematoma evacuation using the MindsEye device. ⋯ Minimally invasive catheter-based and parafascicular approaches using tubular retractors are increasingly recognized as a viable option in the treatment of subcortical lesions. The MindsEye is the first expandable brain access port designed for removal of deep intracranial lesions. We believe it represents a recent addition in the armament of cranial surgeons.
