背景:胡须毛发作为一种重要的额外供体供应,以支持患有广泛脱发且缺乏足够枕部毛发的多毛患者的毛发移植。然而,尚未在东亚人群中广泛研究大规模胡须提取的有效性和安全性。
方法:分析2017年3月至2018年12月在南方医院接受头发移植的广泛性脱发多毛患者的数据。枕骨和胡须在预评估期间分别评估,intra-,和术后时期。使用外径为0.8-0.9mm的中空冲头在膨胀下收获单个胡须毛囊单位(FU)。随访检查安排在3-5天,1个月,术后9个月检查并发症,确定混合的存活率,移植的FU移植物,并评估患者满意度。收集数据并进行统计分析。
结果:总共36个多毛,男性晚期雄激素性脱发(AGA)(Norwood-HamiltonV-VI)患者纳入本研究.枕骨和胡须区的密度分别为78.6±4.6和48.4±9.3FU,分别。从枕骨区收获3135±863FU需要3.1±0.9h,从胡须区收获2352±599FU需要2.1±0.6h。枕骨FU和胡须FU的横切率为3.7±0.4和3.9±0.2%,分别。手术完成时间约为10.0±0.9h,术后5天未报告严重并发症。移植后9个月观察到FU存活率为95.7±1.6%,在裸露的区域没有可见的低色素疤痕。所有患者对所得的美容外观感到满意。
结论:大规模提取胡须,当结合枕毛拔除时,是一种安全有效的治疗方法,可增强具有高级AGA的东亚男性的美容外观。
BACKGROUND: Beard hair serves as an important additional donor supply to support hair transplantation in hirsute patients with extensive alopecia and lacking sufficient occipital hair. However, the efficacy and safety of large-scale beard hair extraction have not been studied extensively in the East Asian population.
METHODS: Data obtained from hirsute patients with extensive alopecia who underwent hair transplantation between March 2017 and December 2018 at Nanfang Hospital were analyzed. Occipital and beard hair were evaluated separately during the pre-, intra-, and post-operative periods. Individual beard hair follicular units (FUs) were harvested under tumescence using a hollow punch with an outer diameter of 0.8-0.9 mm. Follow-up examinations were scheduled at 3-5 days, 1 month, and 9 months postoperatively to check for complications, determine the survival rate of mixed, transplanted FU grafts, and assess patient satisfaction. Data were collected and analyzed statistically.
RESULTS: A total of 36 hirsute, male patients with advanced androgenetic alopecia (AGA) (Norwood-Hamilton V-VI) were included in this study. The density of the occipital and beard areas was 78.6 ± 4.6 and 48.4 ± 9.3 FU, respectively. It took 3.1 ± 0.9 h to harvest 3135 ± 863 FUs from the occipital area and 2.1 ± 0.6 h to harvest 2352 ± 599 FUs from the beard area. The transection rate for occipital FUs and beard FUs was 3.7 ± 0.4 and 3.9 ± 0.2%, respectively. Completion of the operation took approximately 10.0 ± 0.9 h, and no serious complications were reported 5 days after the procedure. An FU survival rate of 95.7 ± 1.6% was observed at 9 months after transplantation, with no visible hypopigmented scars observed in the bare areas. All patients were satisfied with the resulting cosmetic appearance.
CONCLUSIONS: Large-scale beard extraction, when combined with occipital hair extraction, is a safe and effective treatment to enhance the cosmetic appearance of East Asian men with advanced AGA.
