This case study demonstrates a new operative method of eyebrow reconstruction, in which the hair density of the reconstructed eyebrow is controlled by the surgeon and is more similar to that of the uninjured side, resulting in a more natural facial expression and greater aesthetic value for our patients.
The operation was divided into two stages: Stage 1: Implantation of a soft tissue expander into the corresponding subgaleal position of the parietal branch of the superficial temporal artery on the injured side, followed by dilation of the expander until the density of the hair on the expanded scalp reached a suitable value and was lower than that of the uninjured eyebrow. Stage 2: Harvesting of the scalp island flap pedicled by the superficial temporal artery, the end of which was attached to the expanded scalp, followed by the downward movement of the flap to the defect site of the eyebrow via a subcutaneous tunnel, resulting in new eyebrow formation.
In eight cases who were monitored for 4-16 months of follow-up, almost all of the reconstructed eyebrows successfully assumed a desirable shape and exhibited a natural appearance, which was consistent with preoperative expectations; the transplanted hairs were highly similar to those of the original eyebrows. All participants remained healthy after the operation, which was indicated by sufficient blood supply to the expanded flap and normal growth of a new eyebrow without postoperative complications.
Our study demonstrated the excellent performance of an innovative procedure in which a expanded scalp island flap pedicled by the superficial temporal artery was used in the construction of a new eyebrow. It can be performed very safely and reliably to ensure expected results.

本病例研究展示了一种新的眉毛重建手术方法，通过该方法，外科医生可以控制重建眉毛的毛发密度，使其更接近未受伤一侧的毛发密度，从而为患者带来更自然的面部表情和更高的美学价值。
手术分为两个阶段：第一阶段：将软组织扩张器植入受伤侧颞浅动脉顶支相应的帽状腱膜下位置，然后对扩张器进行扩张，直到扩张头皮上的毛发密度达到合适的值且低于未受伤眉毛的毛发密度。第二阶段：切取以颞浅动脉为蒂的头皮岛状皮瓣，将其末端附着于扩张后的头皮，然后通过皮下隧道将皮瓣向下移至眉毛缺损部位，形成新的眉毛。
在8例接受了4 - 16个月随访监测的患者中，几乎所有重建的眉毛都成功呈现出理想的形状且外观自然，与术前预期一致；移植的毛发与原眉毛非常相似。所有参与者术后均保持健康，扩张皮瓣血供充足，新眉毛生长正常，无术后并发症。
我们的研究证明了一种创新手术方法的卓越性能，即采用以颞浅动脉为蒂的扩张头皮岛状皮瓣来构建新眉毛。该方法操作非常安全可靠，能够确保达到预期效果。
