Review Case Reports
Intraspinal Canal Schwannoma with Extensive Calcification: Case Report and Literature Review.
Schwannomas are the most common benign tumors in the intraspinal location, with slow-growing and nonaggressive features. Calcification is not a common histopathological and radiological feature in schwannoma. ⋯ Although intraspinal schwannoma with extensive calcification is rare, which increases the difficulty of an accurate diagnosis preoperatively, the tumor can be completely removed with or without excision of the nonfunctional nerve roots.

Review Case Reports
Calcified or Ossified Chronic Subdural Hematoma: A Systematic Review of 114 Cases Reported during Last Century with a Demonstrative Case Report.
Calcified or ossified chronic subdural hematoma (CSDH), characterized by slowly progressing neurologic symptoms, is a rarely seen entity that may remain asymptomatic for many years. Management of CSDH has improved dramatically in recent years as a result of advances in diagnostic tools, but there is still some controversy regarding the optimal treatment strategy. ⋯ Incidence of calcified or ossified CSDH is high in certain countries, including the United States, Japan, and Turkey, with a steady increase in recent years. The therapy of choice is surgery in these patients and it should be considered in the differential diagnosis at presentation because of its infrequency and variable clinical manifestation, after shunting in children or head trauma in adults.

Traditional retraction to access deep intraparenchymal brain lesions results in vascular disruption. Tubular retractors such as the BrainPath tubular retractor system were developed to reduce retractor-related force injuries via radial dispersion of force. Our study seeks to assess the indications, benefits, and complications associated with BrainPath retractors. ⋯ This report is the first formal assessment of the BrainPath tubular retraction system, highlighting technical considerations of the retractor from the surgeon's perspective, patient outcomes, and complications. The retractor is a safe, efficacious system that can be used for tumor resection or biopsy and hematoma evacuation. However, further randomized controlled trials are indicated to accurately assess complication rates and outcomes.

Patients with single-ventricle congenital heart disease may present for scoliosis correction. These patients undergo a series of cardiac operations that create a novel circulation that has a significant impact on the management of their spinal surgery. ⋯ Patients who have undergone a Fontan procedure can successfully undergo a lengthy scoliosis correction, but it requires multidisciplinary planning.

Randomized Controlled Trial
Hybrid robotics for endoscopic skull base surgery: preclinical evaluation and surgeons' first impression.
A robotic endoscope holder should theoretically provide various advantages in transnasal endoscopic skull base surgery, but only recently has a robotic system become commercially available. The objective of this study was to provide a preclinical evaluation of potential advantages and surgeon first impression of this robotic hybrid solution. ⋯ Endoscopic skull base surgeons seem to view a hybrid robotic solution positively. EndoscopeRobot seems to provide a benefit to the single surgeon with experience in bimanual endoscopic surgery. Further preclinical and clinical evaluation of this technology is necessary.
