This report describes a different approach for diminishing the movements of orbital prosthesis during mimic movements and chewing function. Mechanical devices such as magnets are used to enhance the retention in case lack of the implants. However rigid fixation of obturator and orbital prosthesis can result in movements of the orbital prosthesis during mastication. In this case obturator and orbital prosthesis are combined by magnets. However this combination is not rigid because of an active part which provides movement. This active part allows movements in a space constructed in the acrylic base of orbital prosthesis. Thus, the movements that may occur on orbital prosthesis during chewing can be diminished by this simple mechanism. Due to the fact that designing such a mechanism that minimizes the movements of the orbital prosthesis contributes patient's comfort.

Bilateral anophthalmia, a clinical condition characterized by the absence of globe and ocular tissues from both the orbits, presents considerable challenges to a patient's daily routine and use of prostheses. The patient's inability to orientate custom ocular prostheses (COPs) 3-dimensionally is understandable, and they typically rely on caregivers to manage the prostheses and prevent inadvertent injury to the socket. This clinical report describes the successful integration of braille script into COPs as a solution to these challenges by improving prosthesis management, decreasing caregiver dependence, and encouraging independence.

This study aims to evaluate and compare the usability and performance of mixed reality (MR) technology versus conventional methods for preoperative planning of patient-specific reconstruction plates for orbital fractures. A crossover study design was used to compare MR technology with conventional three-dimensional (3D) printing approaches in the planning of maxillofacial traumatology treatments. The primary focus was on user-friendliness and the accuracy of patient-specific reconstruction planning.

Epithelioid haemangioendothelioma (EHE) is a rare vascular neoplasm characterised by proliferation of vascular endothelial and pre-endothelial cells. The prevalence is less than one in a million people. It is principally observed in the soft tissues of the extremities but can also occur in the bone, brain, liver, lung and lymph nodes.

Purpose: To employ a validated survey for evaluation of quality of life (QoL) outcomes and associated factors in a US cohort of adult patients with acquired anophthalmia wearing a prosthesis.
Methods: A retrospective cohort study was performed at a single, US academic institution of patients cared for between 2012 and 2021. The electronic medical record database was queried for adult patients with a history of evisceration or enucleation surgery and placement of an orbital implant.
