Summary
Virtual surgical planning (VSP) aids craniofacial surgery, but adherence varies. Addressing communication and planning issues improves VSP effectiveness for complex skeletal reconstructions.
Area of Science:
- Craniofacial Surgery
- Medical Technology
- Surgical Planning
Background:
- Virtual surgical planning (VSP) is increasingly utilized in craniofacial surgery.
- Computer-aided design and manufacturing (CAD/CAM) support various craniofacial procedures.
Purpose of the Study:
- To analyze the learning curve and error rates associated with virtual surgical planning in craniofacial procedures.
- To identify factors influencing the successful implementation of VSP.
Main Methods:
- Retrospective analysis of 54 consecutive virtual surgeries (orthognathic and free bone transfers) from July 2012 to October 2016.
- Evaluation of adherence to virtual surgical plans and identification of reasons for plan abandonment.
Main Results:
- 85% of orthognathic VSP were fully adhered to; 4% abandoned, 11% partially adhered.
- 75% of free tissue transfer VSP were adhered to; 25% partially adhered.
- Reasons for abandonment included poor communication, condyle placement issues, soft-tissue impedance, tumor progression, and inadequate preoperative assessment.
Conclusions:
- VSP is a valuable tool in craniofacial surgery, but surgeons must be aware of its limitations.
- Experience and time enhance the utility of VSP as an adjunct to clinical judgment.

The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

6.1K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

A nursing care plan can present in two forms: informal and formal. Informal is a care plan for the individual use of the nurse and goals they wish to accomplish during their shift. Informal care plans are not included in the patient chart. A formal nursing care plan is a written or computerized guide that organizes patient care. It is further subdivided into two: standardized and individualized care plans. Standardized care plans are pre-populated care plans for specific patient populations,...

01:13Principle of Virtual Work: Problem Solving
1.7K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.

01:06Virtual Work for a System of Connected Rigid Bodies
770
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
