The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities.
In case 1, a 24-year-old female patient underwent frontal augmentation surgery with simultaneous maxillomandibular and zygomatic osteotomies to correct facial asymmetry. A silicone implant was fabricated preoperatively using a positive template stone mold of her forehead. In case 2, a 23-year-old female patient underwent total facial contouring surgery including frontal augmentation for improved facial esthetics. A computed tomography (CT)-guided rapid prototype (RP) model was used to make the silicone implants. The operative procedure was safe and simple, and the silicone implants were reliable for a larger degree of frontal augmentation. Six months later, both patients had recovered from the surgery and were satisfied with their frontal shape and projection.
Frontal augmentation with silicone implants can be an effective adjuvant strategy to improve facial esthetics in patients with a flat and narrow forehead who undergo orthognathic reconstruction or total facial contouring surgery.
额头的尺寸和形状决定了面部上三分之一的美学效果。韩国年轻人认为宽阔、平滑、圆润的额头更具吸引力。因此，额部增大术在牙颌面畸形患者中越来越受欢迎。额部增大手术中使用了各种手术方法和材料，各有优缺点。硅胶是额部增大术的理想材料。作者介绍了两例使用预制硅胶植入物对牙颌面畸形女性患者进行美学额部增大术的病例。
病例1，一名24岁女性患者接受了额部增大手术，同时进行了上颌下颌骨和颧骨截骨术以纠正面部不对称。术前使用她额头的正模板石模制作了硅胶植入物。病例2，一名23岁女性患者接受了全面部轮廓整形手术，包括额部增大术以改善面部美学效果。使用计算机断层扫描（CT）引导的快速成型（RP）模型制作硅胶植入物。手术过程安全简单，硅胶植入物在较大程度的额部增大术中可靠。六个月后，两名患者均已从手术中康复，对额头形状和突出度感到满意。
对于接受正颌重建或全面部轮廓整形手术的额头扁平狭窄患者，硅胶植入物额部增大术可以是改善面部美学的有效辅助策略。
