Skull base approach is a neurosurgical challenge requiring dexterity of the operating surgeon for good postoperative outcome. In addition to the experience of the operating surgeon, adequate preoperative information of the tumor is necessary to ensure better outcome. In clinoid meningioma, it is sometimes difficult to determine its relationship with the surrounding structure and the feeding artery. Previously, preoperative simulation has been utilized to determine the intracranial course of the compressed nerves in relation to the petroclival meningioma. We report a case of clinoid meningioma where preoperative fusion of three dimensional computed tomography angiography (3D-CTA) and 3T-fast imaging employing steady-state acquisition (FIESTA) images was useful in determining the exact location of the feeding artery to devascularize the tumor and aid in surgery. Preoperative simulation with three-dimensional digital subtraction angiography (3D-DSA) and 3T-FIESTA fusion images can be a useful adjunct tool to supplement surgery and to train neurosurgical trainees.

Background: Peripheral nerve injury commonly results in pain and long-term disability for patients. Recovery after in-continuity stretch or crush injury remains inherently unpredictable. However, surgical intervention yields the most favorable outcomes when performed shortly after injury.

Introduction: anatomical deformities such as developmental dysplasia of the hip (DDH) and Perthes disease represent a challenge for reconstruction. The use of 3D-printed models can be helpful for assessing the deformity, bone mass, implant size, and orientation.
Objectives: to prospectively evaluate the outcomes of 3D simulation in primary total hip arthroplasty.

Purpose: To use parametric numerical simulation to characterize and compare the differences in corneal biomechanical responses to laser in situ keratomileusis (LASIK) and keratorefractive lenticule extraction (KLEx) under various surgical settings.
Methods: The Finite Element Model was used in a parametric study to evaluate corneal biomechanical responses to LASIK and KLEx, considering variations in preoperative corneal thickness, corneal flap/cap thickness and diameter, refractive correction, and optical zone diameter. Surgery-induced stress, displacement, and interface contact pressure were compared between LASIK and KLEx using the Wilcoxon signed-rank test.

Background: Virtual reality (VR) has shown promise as a nonpharmacological alternative to pharmaceutical pain relievers and anxiety medications in clinical trials by decreasing pain and anxiety in orthopedic surgeries. The aim of the study was to evaluate the impact of VR on these outcomes in individuals undergoing total hip arthroplasty (THA).
Methods: This randomized, controlled, open-label research included 50 participants planned for THA with spinal anesthesia (SA).

Purpose: To evaluate postoperative changes in corneal topographic parameters and higher-order aberrations (HOAs) following Müller muscle-conjunctival resection (MMCR) in patients with mild-to-moderate ptosis.
Methods: This prospective clinical study included patients who underwent MMCR after a positive phenylephrine test and with good levator function who were evaluated. Preoperative and postoperative best-corrected visual acuity (BCVA), margin reflex distance 1 and corneal parameters (flat meridian, steep meridian, simulated keratometry, maximum keratometry), along with HOAs including coma, trefoil, spherical aberration, secondary astigmatism and quadrifoil, were assessed at week 1, month 1 and month 3.
