Summary
This study presents a cost-effective solution for cranial reconstruction using bespoke implants, improving patient outcomes and reducing costs. The developed system enhances skull repair after traumatic brain injury, offering better fit and satisfaction.
Area of Science:
- Neurosurgery
- Biomaterials Engineering
- Medical Device Design
Background:
- Traumatic brain injury (TBI) is a major global health issue, particularly in low- and middle-income countries.
- Craniectomy followed by cranioplasty is crucial for skull integrity and patient recovery after severe TBI.
- Current cranioplasty methods can be costly and may not always provide optimal fit.
Purpose of the Study:
- To develop and implement an integrative surgery management system for cranial reconstructions.
- To create accessible and cost-effective bespoke cranial implants.
- To evaluate the efficacy and safety of bespoke implants in patients undergoing cranioplasty.
Main Methods:
- Bespoke cranial implants were designed for three patients.
- Cranioplasty surgeries were performed using the custom implants.
- Dimensional accuracy and surface roughness of prototype implants were evaluated.
- Patient compliance and quality of life were assessed postoperatively.
Main Results:
- The study successfully designed and implemented bespoke cranial implants for three patients.
- Dimensional accuracy was confirmed across all three axes, with surface roughness measured (minimum Ra of 2.209 μm).
- Patients reported improvements in compliance and quality of life, with no short- or long-term complications observed.
Conclusions:
- The developed system offers an accessible and cost-effective solution for cranial reconstruction using bespoke implants.
- The use of bone cement materials and pre-planning reduced costs and intraoperative times compared to metal implants.
- The study demonstrates improved implant fit, patient satisfaction, and overall outcomes in cranioplasty procedures.
