Few publications are available on eyebrow trichoscopy in patients with alopecia areata and frontal fibrosing alopecia (FFA).
To investigate the validity of using trichoscopy to examine eyebrow involvement in patients with lichen planopilaris (LPP) and FFA.
In this case-control study, 109 patients with eyebrow involvement in LPP and FFA (cases) and with acquired hair disorders of the eyebrows (controls) were included.
Trichoscopy was highly specific and sensitive for the diagnosis of LPP and FFA. Trichoscopic features significantly associated with LPP were peripilar scaling, peripilar pigmentation, broken hairs, peripilar white halos, diffuse empty follicles, and vellus hair. Localized peripilar erythema and empty follicles were significantly associated with the diffuse form of LPP and the zigzag type of FFA. Yellow dots, dystrophic hairs, hair regrowth in different directions, and diffuse empty follicles were associated with LPP activity and FFA severity.
The retrospective nature of the statistical analysis.
Trichoscopy is a valid tool for evaluating eyebrow involvement in LPP and FFA. Thus, it could help increase the diagnostic accuracy and predict the prognosis of eyebrow hair loss at an early stage.
关于斑秃和额部纤维性脱发（FFA）患者的眉毛皮肤镜检查的文献较少。
探讨使用皮肤镜检查扁平苔藓性秃发（LPP）和FFA患者眉毛受累情况的有效性。
在这项病例对照研究中，纳入了109例眉毛受累的LPP和FFA患者（病例组）以及获得性眉毛毛发疾病患者（对照组）。
皮肤镜检查对LPP和FFA的诊断具有高度特异性和敏感性。与LPP显著相关的皮肤镜特征包括毛囊周脱屑、毛囊周色素沉着、断发、毛囊周白色晕、弥漫性空毛囊和毳毛。局限性毛囊周红斑和空毛囊与LPP的弥漫型和FFA的锯齿型显著相关。黄点、营养不良性毛发、不同方向的毛发再生和弥漫性空毛囊与LPP的活动度和FFA的严重程度相关。
统计分析的回顾性性质。
皮肤镜检查是评估LPP和FFA患者眉毛受累情况的有效工具。因此，它有助于提高诊断准确性并在早期预测眉毛脱发的预后。
