The aim of this study was to evaluate the correlation between maxillary defects and facial asymmetry, and to establish categories for visual perception of facial asymmetry. The facial data of 47 patients who underwent maxillary resection due to tumors were captured using stereophotogrammetry. Facial asymmetry was measured using a landmark-independent method and assessed with a Likert scale.

Introduction: Clinical data on osseointegration (OI) for limb replacement indicates a concerning increase in mechanical complications after five years post-implantation. Since adequate bone-implant contact and proper implant alignment are critical factors for successful osseointegration, it is essential to identify the factors influencing these outcomes. This study aimed to assess the effects of residual femur length and implant sizing on bone-implant contact and implant alignment.

Significance: Laparoscopic surgery presents challenges in localizing oncological margins due to poor contrast between healthy and malignant tissues. Optical properties can uniquely identify various tissue types and disease states with high sensitivity and specificity, making it a promising tool for surgical guidance. Although spatial frequency domain imaging (SFDI) effectively measures quantitative optical properties, its deployment in laparoscopy is challenging due to the constrained imaging environment.

Objectives: Mixed reality (MixR) is an innovative visualization tool that presents virtual elements in a real-world environment, enabling real-time interaction between the user and the combined digital/physical reality. We aimed to explore the feasibility of MixR in enhancing preoperative planning and intraoperative guidance for the correction of various complex congenital heart defects (CHDs).
Methods: Patients underwent cardiac computed tomography or cardiac magnetic resonance and segmentation of digital imaging and communications in medicine (DICOM) images was performed.
