2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively. The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.

Coordinates and Map Projections

Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...
FAQs
The key imaging principle is geometric separation. Patient positioning and x-ray beam alignment are coordinated so the pedicles project more clearly, with less overlap from adjacent vertebral structures. This reduces obscuration of the bony anatomy and gives clinicians a more interpretable image for assessing vertebral alignment and features relevant to spinal stability.
Image quality depends mainly on controlled patient positioning and accurate x-ray beam alignment. Small changes in either can alter how the pedicles project relative to neighboring vertebral structures. When these factors are coordinated, superimposition is limited and the resulting image is better suited to evaluating anatomy, abnormalities, or spinal instrumentation.
Neighboring vertebral structures can overlap the pedicles and make their margins or position harder to assess. Limiting this superimposition improves the visibility of the targeted bony anatomy, helping clinicians recognize changes in vertebral alignment, identify fracture-related findings, and evaluate whether visible structures correspond appropriately to the expected spinal anatomy.
The procedure begins with deliberate patient positioning, followed by adjustment of the x-ray beam to project the pedicles clearly. The resulting image is then reviewed for adequate visualization and excessive overlap from adjacent vertebral structures. This workflow connects acquisition technique with interpretation, because positioning and beam alignment directly affect the information available for clinical assessment.
This view can support assessment when clinicians need focused information about vertebral alignment, suspected fractures, bone lesions, or anatomy associated with spinal stability. It may also be relevant when reviewing spinal instrumentation. By concentrating interpretation on the pedicles and their surrounding relationships, the image can contribute to diagnosis and treatment planning.
Clear pedicle visualization helps clinicians assess the position of spinal instrumentation, including pedicle screws, in relation to the vertebral anatomy. This information is relevant when interpreting postoperative or treatment-related images and can support procedural guidance. The value comes from seeing the hardware alongside the bony structures that define its intended anatomical context.
