[Clinical application and curative effect observation of follicular unit extraction and transplantation in the treatment of cicatricial alopecia].

To observe the clinical effect of treatment with follicular unit extraction (FUE) and transplantation in treating cicatricial alopecia. The retrospective cohort study was conducted. From January 2012 to January 2018, 56 patients (36 males and 20 females, aged (25±9) years, 1% to 30% alopecia area of the whole scalp area) who met the inclusion criteria visited the outpatient department of the First Affiliated Hospital of Xi'an Medical University. They were treated with FUE transplantation. The procedure of treatment was performed through the preoperative planning, follicular extraction, follicular preparation, punching recipient site and hair transplantation. The survival rate of hair and density of survived hair were calculated, hair growth and complication were observed. The evaluation was conducted through questionnaire survey by 4 levels: very satisfied, satisfied, not satisfied, and not at all satisfied with effects. After a follow-up of 9 to 24 months, the survival rate of hair in 56 patients was (70±9)%, and the density of survived hair was (35±8) roots/cm. In the evaluation of the curative effect after the first stage surgery, 34 cases (60.7%) were very satisfied, 16 cases (28.6%) were satisfied, and 6 cases (10.7%)thought the treatment was effective but not satisfied. Six unsatisfactory patients and 16 satisfactory patients underwent the second-stage transplantation, with 19 (86.4%) of them being very satisfied and 3 cases (13.6%) satisfied after the second-stage operation. None of the patients underwent the third-stage surgery. The transplanted hairs grew naturally, and there were no serious complications in all cases. FUE transplantation can effectively treat and improve cicatricial alopecia with less trauma, fewer complication, no scar in the donor site and rapid post-operative recovery, so it is worthy of clinical promotion.
