A total of 453 patients with acute injuries of the upper and median zones of the facial skull were examined. The most frequent injury was that to the orbital entrance, fractures of the inferior wall; fractures of the exterior, interior, and anterior walls were less incident, and fractures of the orbital apex were the most rare. Types of the skull bone fractures, associated with injury to the orbital walls, were distinguished. The x-ray semeiotics of injuries to the orbital walls was specified making use of panoramic sonography. Panoramic zonography [correction of sonography] with the use of the Zonark [correction of Sonarc] apparatus helps identify the volume and extension of the injuries on all the orbital walls and is altogether an effective method for the diagnosis of the orbital wall fractures.

Controlling charge transport at the interfaces of nanostructures is crucial for their successful use in optoelectronic and solar energy applications. Mixed-dimensional heterostructures based on single-walled carbon nanotubes (SWCNTs) and transition metal dichalcogenides (TMDCs) have demonstrated exceptionally long-lived charge-separated states. However, the factors that control the charge transport at these interfaces remain unclear.

Purpose: To define the anatomical variance between orbital floor and medial orbital wall blowout fractures, and its change with age.
Methods: This was a retrospective, observational study analyzing data from 557 patients with isolated blowout fractures of the orbital floor or medial orbital wall. Axial and quasi-sagittal CT images were analyzed to compare radiologic data on orbital wall morphology between fracture site groups and among age groups.

Objective: The production of 3-dimensional models and materials according to preoperative virtual surgical planning is a time-consuming process and causes high costs. We aimed to demonstrate the navigation mediated reconstruction of the patients who underwent the removal of a tumoral mass in midfacial region according to their preoperatively prepared surgical plannings.
Study Design: Patients who underwent the removal of tumoral mass and reconstruction in their midfacial region were included in the study.

Various space occupying lesions can arise in the orbit, ranging from developmental anomalies to malignancies, and many of the diseases occurring in children are different from the pathologies in the adult population. As the clinical presentation is frequently nonspecific, radiologic evaluation is essential for lesion detection and characterization as well as patient management. While orbital masses may in some cases involve multiple compartments, a simple compartmental approach is the key for the diagnosis on imaging studies, and MRI is the modality of choice.

Hydrogel scleral buckles are a hydrophilic explant that may lead to significant delayed complications. They can insidiously enlarge over decades and may mimic an orbital tumor or cyst. The authors report a case of an expansive hydrogel scleral explant in a previously eviscerated socket.
