The paranasal area is closely associated with midfacial esthetics. However, there is no special technique available to achieve ideal esthetics paranasal restoration. The present study aims to apply the 3D printed PolyEtherEtherKetone (PEEK) implants as an innovative solution for esthetic paranasal reconstruction. On the basis of the CT scan, the patient-specific PEEK implant and a surgical guiding plate were manufactured aided by a computer. Preoperative and postoperative CBCT data were utilized to evaluate esthetic outcomes. The average follow-up period was 13 months. All patients' wounds healed by first intention. The statistical analysis of preoperative and postoperative esthetic indices revealed light levels of postoperative paranasal depression ( P <0.001) and the wrinkle severity rating scale for nasolabial folds ( P <0.001). Moreover, the nasolabial angle increased ( P <0.05). The established 3D-printing PEEK implanted prosthesis can individually correct the depressed deformity of the paranasal region, and achieve favorable clinical esthetic outcomes.
鼻旁区域与中面部美学密切相关。然而，目前还没有专门的技术可以实现理想的鼻旁修复美学效果。本研究旨在应用 3D 打印聚醚醚酮（PEEK）植入物作为一种创新的鼻旁重建方法。基于 CT 扫描，通过计算机辅助制造患者特定的 PEEK 植入物和手术导向板。利用术前和术后 CBCT 数据评估美学效果。平均随访时间为 13 个月。所有患者的伤口均一期愈合。术前和术后美学指标的统计学分析显示，术后鼻旁凹陷程度较轻（P<0.001），鼻唇沟皱纹严重程度评分（P<0.001）。此外，鼻唇角增大（P<0.05）。所建立的 3D 打印 PEEK 植入物假体可以单独矫正鼻旁区域的凹陷畸形，达到良好的临床美学效果。
