Images in Scalp Ultrasound Before and After Hair Transplant in Frontal Fibrosing Alopecia.

Abstract

Primary cicatricial alopecias are inflammatory scalp conditions that may lead to permanent hair loss and severe alopecia. Frontal fibrosing alopecia is one of the most frequent etiologies of primary cicatricial alopecias. Hair transplant could be a therapeutic option.High-resolution ultrasound (US) is an imaging technique useful for evaluating scalp with adequate differentiation of the skin layers. Also, hair follicles are visualized.The objectives are present presurgical and posttransplant scalp US studies on hair transplant.Frontal fibrosing alopecia is a chronic entity that can progress to extensive irreversible alopecia. Hair transplant is a surgical option. On US, the hair follicles are visualized as thin hypoechoic lines. With Doppler color imaging, it is possible to evaluate vascularization. In this experience, we can observe the follicles of the compromised area before and after the hair transplant and the depth of the implanted follicles.In conclusion, US impresses as a promissory technique for the imaging of hair transplant. More experience is necessary for a better approach of these findings.
