The Synapse02:47

The Synapse

133.2K
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

Synaptic Signaling01:12

Synaptic Signaling

79.5K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Protein-protein Interfaces02:04

Protein-protein Interfaces

14.7K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Area of Science:

  • Plastic Surgery
  • Surgical Simulation
  • Medical Education

Background:

  • Cleft lip surgery demands meticulous planning and 3D spatial understanding for optimal results.
  • Traditional training methods offer limited opportunities for hands-on cleft lip repair practice.
  • A novel physical simulator was engineered to bridge this gap in surgical training.

Purpose of the Study:

  • To develop and evaluate a realistic physical simulator for cleft lip repair and primary rhinoplasty.
  • To assess the fidelity and utility of the simulator in a training context.

Main Methods:

  • Utilized 3D printing, adhesives, and polymers to construct a simulator with multilayered soft tissues, bone, and realistic dissection planes.
  • Experienced cleft surgeons performed simulated cleft lip repairs on the model.
  • Gathered surgeon feedback on the simulator's realism and training value.

Main Results:

  • Seven simulated cleft lip repairs were successfully completed, including Fisher anatomic subunit approximation and rotation advancement techniques.
  • All procedural steps—markings, incisions, dissections, and multilayered closure—were performed effectively.
  • Surgeons unanimously affirmed the simulator's realism and its value as a training instrument.

Conclusions:

  • A comprehensive cleft lip and primary rhinoplasty simulator has been successfully developed and initially tested.
  • This simulator offers a safe and effective platform for surgeons to gain proficiency in cleft lip repair before patient treatment.
