BACKGROUND

As hair transplantation evolved into a procedure in which large numbers of very small grafts are moved in a single session, new problems have emerged. These include greater staffing requirements, longer operating time, additional technical difficulties, and increasing problems with quality control.

OBJECTIVE

To introduce a new surgical instrument, the Rapid Fire Hair Implanter Carousel (Carousel), which can automate the most labor-intensive parts of the hair transplantation process, site creation and implant placement, by combining them into a single step and delivering them in rapid sequence. This instrumentation should help to minimize some of the human factors contributing to graft injury and to simplify and increase the speed of the hair transplant procedure.

METHODS

In a patient with a Norwood IIIA balding pattern, 400 follicular implants were placed into a specific section of the bald scalp. The remainder of the bald scalp was transplanted with 800 follicular implants placed in the traditional way. The two areas were monitored and compared for intraoperative bleeding, ease of placing, total placing time, postoperative healing, and hair growth. Photographic documentation was obtained after surgery and at each postoperative visit.

RESULTS

The Carousel visually produced less bleeding when compared with the manual approach. The Carousel was easier to use than the manual technique, since it eliminated graft insertion as a separate step. This was evidenced by the significantly shorter time required to insert the implants (40 grafts/minute with the Carousel vs 6.6 grafts/minute manually) and the decreased need for secondary manipulation once the grafts were inserted. Postoperative healing of the two groups were the same with regard to the duration of crusting and erythema. The rate of hair growth and the total amount of hair observed at 4 months were the same when identical size areas in test and control sides were compared.

CONCLUSION

In this single patient pilot study, the Carousel greatly facilitated the placement of grafts by decreasing bleeding and obviating the extra step needed for the insertion of the implants. As a result, the total operative time decreased, shortening the time the grafts were outside the body, and decreasing the risk of desiccation and warming. By minimizing the human factor in this labor-intensive part of the procedure, the quality of the hair transplant should increase. It is anticipated that these benefits will result in increased hair yield. Further studies are needed, in a larger patient group, so that these benefits can be demonstrated.

背景

随着毛发移植发展成为一种在单次手术中移植大量非常小的毛囊单位的手术，新问题出现了。这些问题包括人员需求增加、手术时间延长、额外的技术困难以及质量控制方面日益增多的问题。

目的

介绍一种新的手术器械，即快速连发毛发植入旋转盘（旋转盘），它可以通过将毛发移植过程中最耗费人力的部分，即供区创建和植入物放置，合并为一个步骤并快速连续进行，从而实现自动化。这种器械应有助于最大限度减少一些导致毛囊单位损伤的人为因素，并简化毛发移植手术流程并提高其速度。

方法

在一名诺伍德 IIIA 型秃发模式的患者中，将 400 个毛囊植入物放置在秃头皮的特定区域。秃头皮的其余部分以传统方式植入 800 个毛囊植入物。对这两个区域进行监测并比较术中出血情况、放置的难易程度、总放置时间、术后愈合情况以及头发生长情况。术后及每次术后随访均获取照片记录。

结果

与手动方法相比，旋转盘在视觉上产生的出血更少。旋转盘比手动技术更易于使用，因为它省去了单独的毛囊单位插入步骤。这体现在植入物插入所需时间显著缩短（旋转盘为每分钟 40 个毛囊单位，手动为每分钟 6.6 个毛囊单位），并且毛囊单位插入后二次操作的需求减少。两组在结痂和红斑持续时间方面的术后愈合情况相同。当比较测试侧和对照侧相同大小区域时，4 个月时观察到的头发生长速度和头发总量相同。

结论

在这项单病例初步研究中，旋转盘通过减少出血和省去毛囊单位插入所需的额外步骤，极大地便利了毛囊单位的放置。结果，总手术时间减少，缩短了毛囊单位在体外的时间，降低了干燥和受热风险。通过在该手术流程中这一劳动密集型部分最大限度减少人为因素，毛发移植的质量应会提高。预计这些益处将带来更高的毛发产量。需要在更大的患者群体中进行进一步研究，以便证明这些益处。
