[First Experience with Cranioplasty Using the Polyetheretherketone (PEEK) Implant - Retrospective Five-Year Follow-up...

Area of Science:

• Neurosurgery
• Biomaterials Science
• Medical Device Technology

Background:

• Cranioplasty is a common neurosurgical procedure for skull defect repair.
• Autologous bone flaps are preferred but not always feasible due to infection, tumor, or comminution.
• Synthetic implants offer an alternative for complex or unavailable bone grafts.

Purpose of the Study:

• To describe the initial experience and outcomes of using the Cranio-Oss custom implant for cranioplasty.
• To evaluate the safety and efficacy of PEEK implants in skull reconstruction.

Main Methods:

• A total of 26 cranioplasties were performed between 2012-2013.
• Four patients received custom Cranio-Oss (PEEK) implants for large, complex defects.
• Implants were CAD/CAM manufactured based on CT scans and fixed with micro-plates.

Main Results:

• The Cranio-Oss implant demonstrated successful use in four patients with a mean age of 47.
• All cases showed good wound healing and cosmetic outcomes without implant-related revisions.
• Follow-up CT scans confirmed implant stability in situ with no malposition.

Conclusions:

• Cranio-Oss (PEEK) implants are a suitable alternative to autologous bone for cranioplasty when autologous grafts are not viable.
• No complications were reported with the Cranio-Oss implant, supporting its recommendation for skull defect management.
• The importance of synthetic bone substitutes is expected to grow due to logistical and cost factors.
