The aim of this study was to evaluate the surgical outcomes using polyetheretherketone (PEEK) patient-specific prostheses produced by computer-aided design and manufacturing for primary and secondary reconstruction in patients with craniofacial defects.
The study included 13 patients who underwent reconstruction for craniofacial defects using PEEK patient-specific implants (PSI). Eight patients underwent single-step primary reconstruction using individual custom-made surgical guides and custom-made prostheses during the same surgery; five patients underwent delayed reconstruction. The material used to manufacture the implants was PEEK in 13 cases. All patients underwent esthetic examination, ophthalmological examination, and radiological evaluation during the preoperative and follow-up periods. The operation duration and short- and long-term complications were recorded.
The shape and global position of the implants were satisfactory in each case. Fitting of the implant during surgery required extensive adaptation in 1 case and minor in 11 cases. Of 13 implants, 11 adequately restored a morphological complex area with satisfactory cosmetic results. No complications related to the implants were reported.
Reconstruction for cranio-facial defects using PEEK computer-aided designed and manufactured implants is a promising new technique that allows for accurate restoration of the complex 3D anatomy of the craniofacial region.
本研究旨在评估使用计算机辅助设计与制造的聚醚醚酮(PEEK)个体化假体,对颅面缺损患者进行一期和二期重建的手术效果。
本研究纳入了13例使用PEEK个体化植入物(PSI)进行颅面缺损重建的患者。8例患者在同一手术中使用个体化定制手术导板和定制假体进行单步一期重建;5例患者接受延迟重建。13例均使用PEEK材料制造植入物。所有患者在术前和随访期间均接受美学检查、眼科检查和影像学评估。记录手术时间以及短期和长期并发症。
每例患者植入物的形状和整体位置均令人满意。手术中1例植入物需要大量调整,11例需要少量调整。13枚植入物中,11枚充分修复了形态复杂区域,美容效果令人满意。未报告与植入物相关的并发症。
使用PEEK计算机辅助设计和制造的植入物进行颅面缺损重建是一种有前景的新技术,能够精确恢复颅面区域复杂的三维解剖结构。
