摘要

研究目的本研究旨在使用22 MHz超声波评估雄激素性脱发(AGA)患者和健康志愿者头皮各种参数的差异:随机选取2021年9月至2022年6月在苏州大学附属第二医院皮肤科就诊的30名AGA患者(AGA组)和30名健康志愿者(对照组)。AGA患者均符合《中国雄激素性脱发诊治指南》的诊断标准。根据诺伍德-汉密尔顿量表,男性患者的脱发严重程度为 2 至 4 级;根据路德维希量表,女性患者的脱发严重程度为 2 至 3 级。顶点没有进行人工干预,所有检查条件保持一致。对 AGA 组和对照组的顶点头皮进行了频率为 22 MHz 的超声波检查。共测量了七个参数,即表皮+真皮厚度、整个头皮厚度、皮下组织厚度、平均毛囊宽度、平均毛囊长度、毛囊数量以及皮下组织中是否存在彩色血流信号。然后比较这些参数的差异:结果:AGA 组显示整个头皮和皮下组织的厚度减少,平均毛囊宽度变窄,平均毛囊长度变短,毛囊数量减少,顶点区域皮下组织中出现色流信号的次数减少(p 结论:AGA 组的皮下组织中出现色流信号的次数少于 AGA 组:高频(22 MHz)超声波成像可用于观察头皮的入口回声、真皮、皮下组织和毛囊,从而为脱发的临床评估提供成像。

High-frequency ultrasonography of the scalp: A comparison between androgenetic alopecia and healthy volunteers.

Objective: This study aimed to assess differences in various scalp parameters between patients with androgenetic alopecia (AGA) and healthy volunteers using 22 MHz ultrasound.

Methods: Thirty patients with AGA (AGA group) and 30 healthy volunteers (control group) who visited the Department of Dermatology at the Second Affiliated Hospital of Soochow University from September 2021 to June 2022 were randomly selected. The patients with AGA met the diagnostic criteria outlined in the Chinese Guidelines for the Diagnosis and Treatment of Androgenetic Alopecia. The severity of alopecia was assessed for males between grades 2 and 4 on the Norwood-Hamilton scale, and for females between stages 2 and 3 on the Ludwig scale. No artificial interventions were conducted at the vertex, and all examination conditions remained consistent. Ultrasound examinations at 22 MHz were performed on the scalp at the vertex in both the AGA and control groups. Seven parameters were measured, namely, epidermis + dermis thickness, entire scalp thickness, subcutaneous tissue thickness, average follicle width, average follicle length, follicle count, and the presence of color flow signals in the subcutaneous tissue. The differences in these parameters were then compared.

Results: The AGA group showed reduced thickness of the entire scalp and subcutaneous tissue, narrower average follicle width, shorter average follicle length, lower hair follicle count, and fewer instances of color flow signals in the subcutaneous tissue at the vertex area (p < 0.05).

Conclusion: High-frequency (22 MHz) ultrasonography can be employed to visualize the entrance echo, dermis, subcutaneous tissue, and hair follicles of the scalp, thereby providing imaging for the clinical assessment of hair loss.

期刊介绍: Skin Research and Technology is a clinically-oriented journal on biophysical methods and imaging techniques and how they are used in dermatology, cosmetology and plastic surgery for noninvasive quantification of skin structure and functions. Papers are invited on the development and validation of methods and their application in the characterization of diseased, abnormal and normal skin. Topics include blood flow, colorimetry, thermography, evaporimetry, epidermal humidity, desquamation, profilometry, skin mechanics, epiluminiscence microscopy, high-frequency ultrasonography, confocal microscopy, digital imaging, image analysis and computerized evaluation and magnetic resonance. Noninvasive biochemical methods (such as lipids, keratin and tissue water) and the instrumental evaluation of cytological and histological samples are also covered. The journal has a wide scope and aims to link scientists, clinical researchers and technicians through original articles, communications, editorials and commentaries, letters, reviews, announcements and news. Contributions should be clear, experimentally sound and novel.
