Augmented reality (AR) is gaining popularity in gaming, industrial, military, and medical fields. Neurosurgical applications are currently limited and underdeveloped. ⋯ The article discusses the potential and limitations of AR in its current state and identifies strategies for successful AR application in future surgery.

Locked-in syndrome (LIS) is a rare neurologic disorder characterized as quadriplegia with anarthria. The diagnosis of LIS is challenging and requires a high index of suspicion. The syndrome is typically caused by an infratentorial lesion to the ventral pons, regardless of etiology. LIS secondary to supratentorial injury is extremely rare, and to our knowledge, this is the first reported case. ⋯ This is a unique case of incomplete LIS after supratentorial injury. Initial ICU care and early rehabilitation likely played a major role in the full recovery of this patient. The influence of etiology and site of injury on outcome prognosis is also suggested. Although severe diffuse brain injury may occur in the face of an unremarkable computed tomography (CT) scan, the emerging role of magnetic resonance imaging in optimally evaluating traumatic brain injury with discordant clinical and CT information is highlighted and is useful in cases of LIS where prognosis prediction is important.

There is a paucity of studies on readmission rates in elderly patients over a period of 360 days after spinal surgery. ⋯ We found that electrocardiographic abnormalities, male sex, low hemoglobin levels, asthma, heart disease, intensive care unit admission, low aspartate aminotransferase level, high body mass index, and high platelet level were risk factors for readmission. As the postoperative observational period became longer, the reasons for readmission tended to be more related to non-surgical site-related problems than to surgical-related problems.

Anterior clinoidectomy is considered difficult because important structures are adjacent to but hidden behind the anterior clinoid process (ACP). We sought to make anterior clinoidectomy a simpler procedure. ⋯ Visualizing the optic canal in the early stage of the procedure allows anterior clinoidectomy to be performed safely.

Symptomatic postoperative spinal epidural hematoma is a serious complication that may occur after lumbar spine surgery. We analyzed epidural hematoma using postoperative magnetic resonance imaging (MRI) after biportal endoscopic spinal surgery and its impact on clinical outcome. ⋯ The incidence of postoperative spinal epidural hematoma after biportal endoscopic spinal surgery according to postoperative MRI was higher than expected, regardless of the patients' postoperative symptoms. Postoperative hematoma has a decisive influence on postoperative results, and revision surgery might be necessary if canal encroachment is >50% with concomitant symptoms.
