OBJECTIVE The purpose of this study was to compare the outcome of wire osteosynthesis with bone plating in the management of zygomatic complex (ZMC) fractures. The rationale was to enable the oral and maxillofacial surgeon to select either of the treatment procedure with confidence. METHODS In this quasi experimental study, Sixty five patients of ZMC fractures were randomly allocated in group...

Panfacial bone fracture is challenging. Even experienced surgeons find restoration of original facial architecture difficult because of the severe degree of fragmentation and loss of reference segments that could guide the start of facial reconstruction. To restore the facial contour, surgeons usually follow a general sequence for panfacial bone reduction. Among the sequences, the bottom-to-top...

Using freeze-fracture techniques, we have analyzed the glial-axonal junction (GAJ) between Schwann cells and axons in the peripheral nervous system, and between oligodendrocytes and axons in the central nervous system of the rat. We have identified a new set of dimeric-particles arranged in circumferential rows within the protoplasmic fracture faces (P-faces) of the paranodal axolemma in the re...

An experimental system was developed in which the majority of all lymphocyte cell-surface proteins, regardless of antigenic specificity, could be cross-linked and redistributed in the membrane to determine whether this would induce a corresponding redistribution of intramembrane particles (IMP). Mouse spleen cells were treated with P-diazoniumphenyl- beta-D-lactoside (lac) to modify all exposed...

Fractures of the an tenor nasal spine are very rare. A case is reported where a fracture involving the anterior nasal spine was the only significant sequela of a traumatic injury to the face. Appropriate methods of diagnosing such a fracture are discussed.

Intact cells of "Oocystis marssonii" were thin sectioned and freeze-etched, using conventional and double-recovery techniques. Thylakoids extend the length of the single chloroplast and occur in stacks of three to five. The peripheral thylakoids in a stack often alternate between adjacent stacks. Interpretation of double-recovery results suggests that membranes in unstacked regions are asymmetr...

Lombazole, an antimicrobial agent of the imidazole class, induced profound ultrastructural changes in Staphylococcus epidermidis and Candida albicans, as observed by freeze fracture electron microscopy. In S. epidermidis cells, the primary effect on ultrastructure was characterized by a distinct change in the morphology of the plasma membrane. Secondary effects of lombazole were cell wall thick...

We present a family of phase field models for fracture in piezoelectric and ferroelectric materials. These models couple a variational formulation of brittle fracture with, respectively, (1) the linear theory of piezoelectricity, and (2) a Ginzburg Landau model of the ferroelectric microstructure to address the full complexity of the fracture phenomenon in these materials. In these models, both...

METHODS: All operative facial trauma over a 16 year period (1998 – 2013) at a single institution was reviewed. Patients were categorized based on the imaging modality (head or face scan) used to evaluate their facial fractures, excluding those receiving a single imaging study. Fracture patterns seen were categorized and patients receiving both scan types were grouped based on whether the result...
