[Additive technologies in neurosurgery]

Area of Science:

• Neurosurgery
• Medical Engineering
• Biomaterials Science

Background:

• Advancements in additive technologies (ATs), including 3D printing, are increasingly integrated into neurosurgical practice.
• Complex surgical interventions necessitate meticulous planning and advanced training for neurosurgeons.
• Accurate 3D models aid in surgical planning and visualization of anatomical regions.

Purpose of the Study:

• To highlight the role and applications of additive technologies in modern neurosurgery.
• To emphasize the benefits of 3D modeling and 3D printing in surgical planning and training.
• To showcase the utility of ATs in reconstructive surgery, particularly for skull defects.

Main Methods:

• Utilizing additive technologies for the generation of precise anatomical and implant models.
• Developing custom molds for intraoperative fabrication of implants using materials like polymethyl methacrylate (PMMA).
• Fabricating patient-specific implants from titanium alloys and polyetheretherketone (PEEK) for surgical use.

Main Results:

• Additive technologies facilitate the creation of accurate, patient-specific skull models for surgical planning.
• ATs enable the efficient development and production of custom molds for intraoperative implant formation.
• Individualized implants made from advanced materials like titanium and PEEK can be fabricated for direct surgical application.

Conclusions:

• Additive technologies significantly improve the planning and execution of complex neurosurgical procedures.
• 3D printing and ATs offer versatile solutions for reconstructive surgery, especially in addressing skull defects.
• The integration of ATs enhances the capabilities of neurosurgeons, leading to more precise and effective treatments.
