Introduction Even though orbital complications in acute rhinosinusitis are not very common, they can be very severe complications, with high mortality rates, due to infection spreading to orbital and intracranial tissues (1). Especially due to intracranial complications, acute rhinosinusitis is considered in the life-threatening disease group. As per Chandler et al. (2), orbital complications a...

Purpose To report a case of lagophthalmos caused by cicatricial adhesion of orbital adipose tissue to the orbital roof. Observations A 23-year-old female was presented with right lagophthalmos. Five months prior to consult at our clinic, she suffered from a penetrating trauma to the frontal lobe of the brain through the right orbital roof with cerebrospinal fluid leakage. Decompressive cranie...

For the first time, the nuclear magnetic resonance (NMR) spin-spin coupling mechanism is decomposed into one-electron and electron-electron interaction contributions to demonstrate that spin-information transport between different orbitals is not exclusively an electron-exchange phenomenon. This is done using coupled perturbed density-functional theory in conjunction with the recently developed...

High harmonic generation in the interaction of femtosecond lasers with atoms and molecules opens the path to molecular orbital tomography and to probe the electronic dynamics with attosecondÅngström resolutions. Molecular orbital tomography requires both the amplitude and phase of the high harmonics. Yet the measurement of phases requires sophisticated techniques and represents formidable chall...

Unlike charge and spin, the orbital degree of freedom of electrons in transition metal oxides is difficult to detect. We present a theoretical study of a new detection method in metallic orbitally active systems by analyzing the quasiparticle scattering interference (QPI) pattern of the spectroscopic imaging scanning tunneling spectroscopy, which is sensitive to orbital structures and orbital o...

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 or...
