Background : The scar alopecia after cranioplasty (SAC) may decrease the patient's quality of life. We have treated SAC using follicular unit extraction (FUE). The aim of this study was to discuss that efficacy of FUE and how much hair follicular unit (FU) should be transplanted intraoperatively for the treatment of SAC.
Methods : We treated 10 patients (4 men and 6 women) who had SAC using FUE.
Results: The average age, alopecia size, and intraoperative hair density on the graft area were 29.8?±?12.1 years, 29.8?±?44.5?cm2, and 34.6?±?11.8 FU/cm2, respectively. One year postoperatively, the average hair survival rate on the graft area was 66.3?±?6.1%. Hair appearance was rated as good in six, fair in three, and poor in one. Among patients whose 1-year postoperative hair density was ≥ 20 FU/cm2, five of six patients achieved good results. However, among patients whose 1-year postoperative hair density was?
Conclusions: FU excision is useful for the treatment of scar alopecia after craniotomy. Our results suggest that the 1-year postoperative hair density should exceed 20 FU/cm2 to achieve good outcomes.
