Purpose: The purpose of the study was to evaluate the diagnostic value of ultrasonography to determine medial and lateral orbital wall fractures.
Materials And Methods: Sixty-two patients with the clinical diagnosis of an orbital trauma underwent coronal computed tomography (CCT) and ultrasonographic investigation (US). Inclusion criteria were clinically suspected orbital injuries defined by reduced bulbus motility, diplopia, or additional traumatic injuries of the orbit or the globe. US and CCT were used as imaging diagnostic methods.
Results: Ultrasonography showed a sensitivity of 56%, a specificity of 95%, and an accuracy of 88% at the medial orbital rim. Regarding the lateral orbital rim, ultrasonography showed a sensitivity of 92%, a specificity of 88%, and an accuracy of 90% using CCT as a reference method.
Conclusion: Ultrasonography with a curved-array scanner seems to be a valuable method in the detection of lateral orbital wall fractures. Further studies have to be done to improve sensitivity in the interpretation of medial orbital wall fractures.

Objective: to study the anatomical feasibility of laser fiber insertion for interstitial thermal therapy via transorbital approach to the temporo-mesial structures (amygdala-hippocampus-parahippocampus complex).
Methods: Anatomical dissections were performed bilaterally on two human cadaveric heads via a transorbital approach, in which screws and laser fibers were used for magnetic resonance imaging-guided laser interstitial thermal therapy (MRIgLITT) assisted by neuronavigation. In addition, eight transorbital trajectories were simulated using the transorbital entry points obtained from a cadaveric radiological study of four patients previously operated on for mesial temporal lobe epilepsy.

Ablepharon macrostomia syndrome is a rare congenital disorder caused by autosomal-dominant mutations. This condition is characterized by redundant skin, low-set ears, macrostomia, ambiguous genitalia, and underdevelopment of the both upper and lower eyelids. The shortening of the anterior lamella, septum and levator aponeurosis lead to a severe corneal exposure within the first hours of life.

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.

Transverse optical gradient force in untethered rotating metaspinners.

Nanostructured dielectric metasurfaces offer unprecedented opportunities to control light-matter momentum exchange, and thereby the forces and torques that light can exert on matter. Here we introduce optical metasurfaces as components of ultracompact untethered microscopic metaspinners capable of efficient light-induced rotation in a liquid environment. Illuminated by weakly focused light, a metaspinner generates torque via photon recoil through the metasurfaces' ability to bend light towards high angles despite their sub-wavelength thickness, thereby creating orbital angular momentum.
