Summary
A new method quantifies flap pliability, crucial for head and neck reconstruction. This flap pliability score (FPS) helps assess flap suitability for surgical sites.
Area of Science:
- Plastic Surgery
- Biomechanical Engineering
- Surgical Innovation
Background:
- Flap pliability, the ability to bend within spatial constraints, lacks a standardized quantitative measurement.
- Assessing flap flexibility is critical for successful reconstructive surgery, particularly in head and neck procedures.
Purpose of the Study:
- To introduce and validate a novel measuring mechanism for quantifying flap pliability.
- To establish a flap pliability score (FPS) for objective assessment of flap flexibility.
Main Methods:
- A novel measuring mechanism was applied to free flaps used in head and neck reconstruction between January 2015 and January 2017.
- A flap pliability score (FPS) was assigned to 40 profunda artery perforator (PAP) flaps and 52 anterolateral thigh (ALT) flaps.
- Correlations between FPS and common variables were observed.
Main Results:
- Proximal profunda artery perforator (PAP) flaps demonstrated greater pliability compared to their distal ends.
- Distal anterolateral thigh (ALT) flaps exhibited higher pliability than their proximal ends.
- The study identified specific patterns of pliability within PAP and ALT flaps.
Conclusions:
- The developed technique allows for the objective measurement of flap pliability at proximal and distal ends of PAP and ALT flaps.
- This innovative measuring mechanism provides a quantifiable flap pliability score (FPS).
- The FPS aids in determining flap suitability for specific recipient sites in reconstructive surgery.

As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

01:29Potential Due to a Polarized Object
748
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Magnetic dipoles in magnetic materials are aligned when placed under an external magnetic field. For paramagnets and ferromagnets, dipole alignment occurs in the direction of the magnetic field. However, the dipoles align opposite to the field in the case of diamagnets. This state of magnetic polarization due to the external field is called magnetization. Magnetization is defined as the dipole moment per unit volume. It plays a similar role to polarization in electrostatics.

17.5K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...
