PURPOSE
The aim of this study was to evaluate polyetheretherketone (PEEK) as a patient-specific implant (PSI) material in maxillofacial reconstructive surgery.
MATERIALS AND METHODS
The retrospective study included a cohort of 24 patients who underwent maxillofacial surgery using PEEK PSIs. Each patient underwent preoperative multislice computed tomography (CT) with 0° tilt of gantry. Based on the CT scan, the PEEK PSIs were planned and manufactured using three-dimensional (3D) modeling and computer-aided design/computer-aided manufacturing (CAD/CAM) techniques. All procedures were performed under general anesthesia. Implants were placed intraorally, extraorally or through subciliary, transconjuctival or coronal incisions.
RESULTS
In 22 of 24 cases, the PEEK PSI fit well without adjustments. Although the fit to the surrounding bone was perfect in almost all of the cases, the outer contour of the PSI was modified in nine cases before fixation. However, intraoperative implant modification did not affect the infection rate. In two cases, postoperative wound dehiscence and infection needed additional treatment and healed without removal of the implants.
CONCLUSION
The follow-up data in this study showed good outcomes with reliable results for PSI made of PEEK in the maxillofacial region.
目的
本研究旨在评估聚醚醚酮（PEEK）作为一种患者特异性植入物（PSI）材料在颌面重建手术中的应用。
材料和方法
本回顾性研究纳入了 24 例接受 PEEK PSI 颌面手术的患者。每位患者均行术前多层螺旋 CT（0°机架倾斜）。基于 CT 扫描，使用三维（3D）建模和计算机辅助设计/计算机辅助制造（CAD/CAM）技术规划和制造 PEEK PSI。所有手术均在全身麻醉下进行。植入物通过口腔内、口腔外或经下睑缘、经结膜或冠状切口植入。
结果
在 24 例病例中，22 例 PEEK PSI 无需调整即可良好适配。尽管几乎所有病例的 PSI 与周围骨的贴合都非常完美，但在固定前，有 9 例病例对 PSI 的外轮廓进行了修改。然而，术中对植入物的修改并未影响感染率。在 2 例病例中，术后伤口裂开和感染需要额外的治疗，并在不取出植入物的情况下愈合。
结论
本研究的随访数据显示，颌面区域使用 PEEK 制成的 PSI 具有可靠的结果，可获得良好的效果。
