背景。毛囊单位移植（FUT）是使用通过单条收获和立体显微镜解剖获得的大量自然发生的单个毛囊单位进行的。条带切除造成的供体伤口疤痕虽然是一种罕见的并发症，但仍然引起足够多的患者的关注，因此有必要采取替代解决方案。 目的。本文的目的是介绍毛囊单位提取术（FOX 手术），即通过非常小的打孔切除直接从供体区域取出单个毛囊单位，并描述一种确定哪些患者适合该手术的测试（FOX 测试）。本文探讨了毛囊单位提取 (FUE) 的细微差别、局限性和实践方面。方法。 FUE 使用 1 毫米的打孔器将毛囊单位与周围组织分离，直至真皮中部水平。随后用镊子提取毛囊单位。 FOX 测试的开发是为了确定哪些患者适合该手术。该测试对 200 名患者进行。对 FOX 阳性和 FOX 阴性的代表性患者进行组织学研究。 结果。 FOX 测试可以确定哪些患者适合 FUE。大约 25% 的活检患者是 FUE 的理想候选者，35% 的活检患者是提取的良好候选者。结论。 FUE 是一种微创毛发移植方法，无需线性供体切口。对于某些患者来说，该技术可以作为传统毛发移植的重要替代方案。
BACKGROUND. Follicular Unit Transplantation (FUT) is performed using large numbers of naturally occuring individual follicular units obtained by single-strip harvesting and stereo-microscopic dissection. Donor wound scarring from strip excision, although an infrequent complication, still concerns enough patients that an alternative solution is warranted.OBJECTIVE. The purpose of this paper is to introduce Follicular Unit Extraction (The FOX Procedure), in which individual follicular units are removed directly from the donor region through very small punch excisions, and to describe a test (The FOX Test) that determines which patients are candidates for this procedure. This paper explores the nuances, limitations, and practical aspects of Follicular Unit Extraction (FUE).METHODS. FUE was performed using 1-mm punches to separate follicular units from the surrounding tissue down to the level of the mid dermis. This was followed by extraction of the follicular units with forceps. The FOX test was developed to determine which patients would be good candidates for the procedure. The test was performed on 200 patients. Representative patients who were FOX-positive and FOX-negative were studied histologically.RESULTS. The FOX Test can determine which patients are suitable candidates for FUE. Approximately 25% of the patients biopsied were ideal candidates for FUE and 35% of the patients biopsied were good candidates for extraction.CONCLUSION. FUE is a minimally invasive approach to hair transplantation that obviates the need for a linear donor incision. This technique can serve as an important alternative to traditional hair transplantation in certain patients.
