Purpose: The aim of our retrospective study was to evaluate the feasibility, safety, and diagnostic yield of a frameless method for stereotactic neurosurgical procedures in pediatric patients.
Methods: Twenty-two frameless stereotactic neurosurgical procedures (18 biopsies, 4 catheter placements), using a modified frameless stereotactic navigational system, were performed in 21 pediatric patients in our institution from 2004 to 2009. All procedures were performed by the senior authors (AAK, SC).
Results: We completed 18 biopsy procedures in 18 patients, yielding usable diagnostic specimens in 100% of the procedures. Of this biopsy group, two patients experienced an asymptomatic hemorrhage per CT, and one patient experienced a transient hemiparesis, recovering to baseline within 1 week after surgery. Four catheter placement procedures were completed in three patients, including one patient who had to have the procedure repeated. We had no peri-operative mortality or technical difficulties related to the catheter placements.
Conclusions: Frameless stereotactic neurosurgical procedures in the pediatric population are feasible and can be completed safely for histological tumor diagnosis as well as for accurate placement of intracranial catheters. This method has low rates of morbidity comparable to frame-based procedures, with the advantage of greater operative convenience.

Purpose: Uveal melanoma (UM) represents the most prevalent and aggressive intraocular malignancy in adults. This study examined the outcomes of patients diagnosed with high-risk UM who underwent fractionated stereotactic radiosurgery (fSRS) treatment utilizing a novel LINAC-based frameless technique.
Design: Retrospective, interventional case series.

Background: We assessed the accuracy and performed a directional analysis of robot-assisted implantation of stereoelectroencephalography (SEEG) depth electrodes in children using the frameless neurolocate 3D registration module.
Methods: Thirteen children with epilepsy undergoing stereotactic robot-assisted insertion of SEEG electrodes were included. Six children were operated on with standard frame-based registration while 7 with the use of the frameless neurolocate registration module.

Introduction: Non-invasive frameless systems have paved its way for stereotactic radiotherapy treatments compared to gold standard invasive rigid frame-based systems as they are comfortable to patients, do not have risk of pain, bleeding, infection, frame slippage and have similar treatment efficacy.
Aim And Objective: To estimate immobilisation accuracy (interfraction and intrafraction) and PTV margins with double shell positioning system (DSPS) using daily image guidance for stereotactic radiotherapy in patients with brain tumors.
Materials And Method: A prospective study was done in 19 cranial tumor patients with KPS ≥70, immobilized by the DSPS with mouth bite and treated with LINAC based image guided stereotactic radiotherapy.

Objective: Robotics in neurosurgery is becoming increasingly prevalent. The integration of intraoperative imaging for patient registration into workflows of newer robotic systems enhances precision and has further driven their widespread adoption. In this study, the authors report on a lightweight, table-mounted robotic system integrating robotic cone-beam CT (CB-CT) for automated patient registration in cranial biopsies and stereotactic electroencephalography (sEEG).
