Summary
Personalized 3D-printed skull base surgery (SBS) models offer a high-fidelity simulation for training. This practical approach enhances anatomical education and surgical skills for transnasal endoscopic procedures.
Area of Science:
- Neurosurgery
- Medical Simulation
- 3D Printing Technology
Background:
- Transnasal endoscopic skull base surgery (SBS) poses significant challenges for neurosurgeons due to complex anatomy and limited visualization.
- Developing effective training methods is crucial for improving surgical outcomes and patient safety.
Purpose of the Study:
- To design and evaluate a personalized, multimaterial, and multicolor 3D-printed simulation for skull base surgery (SBS) training.
- To assess the fidelity and feasibility of the 3D-printed model for anatomical education and surgical skill development.
Main Methods:
- Personalized 3D models were created from CT and MRI scans of a volunteer using a multimaterial 3D printer.
- Fidelity was assessed by 3 experienced neurosurgeons, and training effectiveness was evaluated by 10 resident trainees using Likert questionnaires.
Main Results:
- The 3D-printed models demonstrated high fidelity in tissue structure representation (mean scores 3.7-4.7).
- Participants reported significant aid in anatomical education (mean scores 3.5-4.9) and surgical training (mean scores 3.5-4.9).
Conclusions:
- 3D-printed SBS simulations are practical, economical, and high-fidelity training tools.
- These models hold substantial potential for enhancing anatomical education and operative training in transnasal endoscopic surgery.

01:22Sutures of the Skull
13.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:08Overview of the Skull
8.1K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

1.5K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
