This study introduces a novel cranioplasty technique using miniplates and acrylic, enhancing cosmetic results and prosthesis resilience for cranial defect repair. The reinforced concrete method improves adherence and contouring for better patient outcomes.

Area of Science:

  • Neurosurgery
  • Plastic Surgery
  • Biomaterials

Background:

  • Cranioplasty is common for cranial defects from trauma, infection, or tumors.
  • Current acrylic cranioplasty has limitations in bone adherence and cosmetic contouring, especially for complex defects like orbital rim involvement.
  • Continuous development of cranioplasty techniques is essential.

Purpose of the Study:

  • To present a novel cranioplasty technique.
  • To address limitations of traditional acrylic cranioplasty.
  • To improve cosmetic outcomes and prosthesis durability.

Main Methods:

  • A technique utilizing miniplates as struts for acrylic application was developed.
  • The acrylic is applied using a "reinforced concrete" principle.

  • Ten consecutive cranioplasties were performed using this new method over five years.

    • Main Results:

    • All ten patients achieved excellent cosmetic results.
    • No complications were reported in the series.
    • The technique facilitated contouring during acrylic curing.

    Conclusions:

    • The described miniplate-reinforced acrylic cranioplasty technique offers superior cosmetic results.
    • This method provides a more resilient prosthesis compared to traditional techniques.
    • The technique is effective for complex cranial defects, including those involving the orbital rim.
