Paradigm Shift in Materials for Skull Reconstruction Facilitated by Science and Technological Integration

Area of Science:

• Neurosurgery
• Biomaterials Science
• Orthopedic Surgery

Background:

• Cranioplasty is a surgical procedure to repair skull bone defects resulting from trauma or previous surgery.
• Historically, various materials have been employed, with ongoing evolution driven by advancements in biomedical technology.
• The optimal material for cranioplasty remains a subject of debate, necessitating continued research into both biologic and nonbiologic alternatives.

Purpose of the Study:

• To provide a comprehensive overview of the materials and techniques utilized in cranioplasty.
• To discuss the historical evolution of cranioplasty materials and their impact on patient outcomes.
• To highlight the ongoing search for the ideal biomaterial for skull reconstruction.

Main Methods:

• Review of historical and contemporary cranioplasty materials, including autologous bone, titanium (plate/mesh), and prefabricated customized implants.
• Discussion of surgical techniques involved in raising the scalp and reshaping the skull.
• Exploration of current research trends in biologic and nonbiologic reconstructive materials.

Main Results:

• Cranioplasty techniques have evolved significantly, utilizing diverse materials to restore cranial contour and function.
• Materials range from autologous bone grafts to advanced synthetic options like titanium and custom biomaterial implants.
• No single material has been universally agreed upon as optimal, indicating a need for further investigation.

Conclusions:

• Cranioplasty is a well-established surgical intervention for cranial bone defects.
• The selection of materials for cranioplasty is critical for achieving successful patient outcomes.
• Continued research into novel biomaterials is essential for advancing the field of cranial reconstruction.
