Forehead augmentation have become popular aesthetic procedures among Asians in recent years. However, the use of polyetheretherketone (PEEK) patient-specific implant (PSI) in the facial contouring surgery for aesthetic considerations is not well documented in the existing studies. The purpose of this study was to develop a novel method for forehead augmentation and assess the clinical outcomes and complications in patients who underwent forehead augmentation with PEEK PSI assisted by endoscopy.
The PEEK PSIs were fabricated using the virtual surgical planning (VSP) and the computer-aided manufacturing (CAM) for each patient, preoperatively. The implant pockets were dissected in the subperiosteal plane, and PEEK PSIs were placed in their designed position and fixed assisting by endoscopy via small incision within the hairline. All patients were asked to complete the FACE-Q questionnaire before and 6 months after the operation. Pre- and postoperative demographics, photographs, and other clinical data of patients were collected and analyzed.
11 patients underwent forehead augmentation were enrolled in this study. All procedures were completed successfully with the help of endoscope. The average patient age was 30.63 ± 2.54 years. The mean thickness and size of PEEK PSI were 4.44 ± 1.77 mm and 38.43 ± 22.66 cm, respectively. The mean operative time was 83.00 ± 29.44 min, and the mean postoperative follow-up period was 11.00 ± 6.50 months. No implant exposure, extrusion or removal were reported. The FACE-Q scores of patients in satisfaction with the forehead increased from 47.64 ± 7.15 to 78.81 ± 6.35.
PEEK PSIs can be prefabricated to achieve accurate remodeling of the frontal contour with good esthetic outcomes. The endoscope provides direct and magnified vision, which allow easy access to the supraorbital rim and lateral edge of the eyebrow arch and confirming the position of the implants without damaging nerves and vessels. Endoscopic-assisted forehead augmentation with PEEK PSI is safe and effective.

近年来，额部填充术在亚洲人群中越来越受欢迎。然而，在面部轮廓整形手术中，出于美学考虑，使用聚醚醚酮（PEEK）患者特异性植入物（PSI）的相关研究并不充分。本研究旨在开发一种新的额部填充方法，并评估内窥镜辅助下 PEEK PSI 行额部填充术的临床效果和并发症。
术前使用虚拟手术规划（VSP）和计算机辅助制造（CAM）为每位患者定制 PEEK PSI。在骨膜下平面切开植入物袋，通过发际线内的小切口在内窥镜的辅助下将 PEEK PSI 放置在设计的位置并固定。所有患者均在手术前和手术后 6 个月完成 FACE-Q 问卷。收集并分析患者的术前和术后人口统计学资料、照片和其他临床数据。
本研究共纳入 11 例行额部填充术的患者。所有手术均在内窥镜的帮助下顺利完成。患者平均年龄为 30.63±2.54 岁。PEEK PSI 的平均厚度和大小分别为 4.44±1.77mm 和 38.43±22.66cm。平均手术时间为 83.00±29.44min，平均术后随访时间为 11.00±6.50 个月。无植入物暴露、挤出或取出。患者对额部满意度的 FACE-Q 评分从 47.64±7.15 分增加到 78.81±6.35 分。
PEEK PSI 可预先制作，实现额部轮廓的精确重塑，具有良好的美学效果。内窥镜提供直接和放大的视野，允许轻松进入眶上缘和眉弓外侧缘，并确认植入物的位置，而不会损伤神经和血管。内窥镜辅助 PEEK PSI 行额部填充术是安全有效的。
