Early use of follicular unit excision (FUE) as a method of hair transplantation was limited by high rates of hair follicle transection. This hurdle has been overcome by innovative methods, punch shapes, and devices. With the vast array of tools available, it can be difficult for hair transplant surgeons to choose the best option for their practices.
To provide an in-depth review and comparison of currently available FUE methods, punch designs, and motorized devices, and discuss how these tools fit the unique skin and hair characteristics of patients.
A review of the literature and available information on FUE methods, punches, and devices, as well as the authors' experience in this area, is provided.
Innovative FUE methods, punch shapes, and motorized devices have successfully minimized the rate of hair follicle transection. Methods include the use of sharp punches with depth control, and blunt rotating punches. Punch shapes such as flared, hybrid, and edge out have successfully reduced transections by keeping the cutting edge away from the follicles under the skin. The development of motorized devices using features including rotation, roto-oscillation, oscillation, vibration, suction, and hydration has also aided in achieving more successful graft excision.
Follicular unit excision is a widely used technique by hair restoration surgeons. Therefore, it is important for physicians to be aware of the array of punches and devices available and understand how these tools can be used to adapt to the unique skin and hair characteristics of individual patients to optimize successful graft harvesting.
早期使用毛囊单位提取术（FUE）作为一种毛发移植方法，受到毛囊横断率高的限制。这一障碍已通过创新方法、打孔器形状和器械得以克服。由于有大量工具可供选择，毛发移植外科医生可能难以选择最适合其业务的选项。
对当前可用的FUE方法、打孔器设计和电动器械进行深入回顾和比较，并讨论这些工具如何适应患者独特的皮肤和毛发特征。
提供对FUE方法、打孔器和器械的文献及可用信息的回顾，以及作者在该领域的经验。
创新的FUE方法、打孔器形状和电动器械已成功将毛囊横断率降至最低。方法包括使用带深度控制的锋利打孔器和钝性旋转打孔器。诸如喇叭形、混合型和边缘外扩形等打孔器形状，通过使切割边缘远离皮下毛囊，成功减少了横断。利用旋转、旋转振荡、振荡、振动、抽吸和水合等功能开发的电动器械，也有助于实现更成功的移植物提取。
毛囊单位提取术是毛发修复外科医生广泛使用的技术。因此，医生了解可用的打孔器和器械阵列，并理解如何使用这些工具来适应个体患者独特的皮肤和毛发特征以优化成功的移植物采集非常重要。
