Biportal endoscopy spine surgery is an endoscopic procedure that uses 2 portals, 1 for the endoscope and 1 for the instruments. It provides an excellent and very versatile field of view, with the advantage of another portal to approach the most common degenerative lumbar pathologies. ⋯ Biportal endoscopy is a minimally invasive procedure that is safe and effective, with a low rate of complications. It has a reproducible learning curve and provides very good outcomes regarding functionality and pain scores.

Results of C4-C6 laminoplasty with C3 laminectomy and C3-C6 laminoplasty were compared retrospectively. ⋯ If the C2 interspinous angle is wide and intraoperative semispinalis capitis damage can be minimized, it is worth trying C3 laminoplasty, but if the C2 inter-spinous angle is narrow, C3 laminectomy is recommended from the beginning.

Intraoperative ultrasound is a promising tool for intraoperative tumor resection control. Navigated three-dimensional US (n3DUS) has many benefits over standard two-dimensional US (2DUS). ⋯ Good delineation, noneloquent location, and use of n3DUS was associated with a higher probability of GTR in glioma surgery. Surgeons' experience did not influence the extent of resection. Morbidity was predominantly associated with eloquent location, independent of all other factors.

The incidence of mortality after treatment of unruptured intracranial aneurysms (UIAs) has been described historically. However, many advances in microsurgical treatment have since emerged, and most available data are outdated. We analyzed the incidence of mortality after microsurgical treatment of patients with UIAs treated in the past decade. ⋯ A low mortality rate is associated with recent microsurgical treatment of UIAs. However, nonsaccular aneurysms and higher American Society of Anesthesiologists grades appear to be predictors of mortality.

The main goal of this retrospective study was to examine the morphology of the interthalamic adhesion (ITA) in normal children aged between 1 and 18 years. ⋯ ITA size irregularly decreases with advancing age from 1 to 18 years. Our calculated linear functions, showing the growth dynamics of the ITA by pediatric ages, may be helpful in estimating its dimension.
