     摘要

     目的：分析汉族人的头发分布特征。方法：本实验通过对146例健康汉族正常人和41例雄激素性脱发(AGA)患者进行系统性分析。实验使用图像分析软件计算正常人及雄激素秃发患者的头顶、颞部和枕部的毛囊单位数(FUs)和毛发数目。结果:146名健康汉族人的平均毛囊密度为74.36×13.33单位/平方厘米，平均毛发密度为143.33×28.08根 /平方厘米，且男性和女性之间的差异无统计学意义(P>0.05)。41名AGA患者枕部平均毛囊密度为77.78×2.99单位/平方厘米，平均毛发密度为148.12×6.98根/平方厘米，均低于健康汉族，且差异有统计学意义(P< 0.001)。双根毛发的毛囊是汉族主要的类型。结论：健康汉族人的头发和头发密度低于白种人和非洲人。本实验将为毛发移植外科医生提供了有关中国汉族人头发分布的信息，为毛发移植手术的供体部位和移植密度提供了定量依据。这些数据也将有助于毛发移植外科医生的术前评估、手术计划和术后效果评估。

     Aim: To explore the characteristics of normal hair distribution in Han Chinese. Methods: A total of 146 healthy Han Chinese and 41 patients with androgenetic alopecia (AGA) were selected as research subjects. Digital photographs of the vertex, temporal, and occipital regions were taken after their hair was trimmed. An image analysis software was used to compute the number of follicular units (FUs) and hairs. Results: The mean FU density of the 146 healthy Han Chinese was 74.36 ± 13.33 units/cm² and their mean hair density was 143.33 ± 28.08 hairs/cm². There was no significant difference between males and females (P > 0.05). The mean FU density in the occipital region of AGA patients was 77.78 ± 2.99 units/cm² and their mean hair count was 148.12 ± 6.98 hairs/cm². Both were lower than those of healthy Han Chinese, and the differences were statistically significant (P < 0.001). Two-hair FUs (52.62%) were the predominant type found in Han Chinese. Conclusion: The FU and hair densities of healthy Han Chinese are lower than those of whites and Africans. the study provides hair transplantation surgeons with information on hair distribution in Han Chinese. It also provides a quantitative basis for the area of donor site and transplantation density necessary for hair transplantation surgeries. the research findings provide some theoretical data for the hair distribution characteristics of Han Chinese. These data can contribute to the preoperative assessment, surgery planning, and postoperative outcome evaluation by hair transplantation surgeons.
