Survival of grafts in coup de sabre.

[BACKGROUND] Treatment of coup de sabre must remain conservative until the disease is no longer in an active state. When activity has ceased, some operative intervention is safe and effective for the correction of deformity. While hair transplantation showed high survival rates for the correction of cicatricial alopecia, it has not yet been reported to be performed for the correction of coup de sabre.

[OBJECTIVE] To examine the therapeutic possibility of hair transplantation for the correction of coup de sabre.

[METHODS] Follicular units consisting of two to three hairs from the patient's occipital scalp were transplanted using Choi hair transplanters.

[RESULTS] Ten-month follow-up studies showed an 86.5% survival rate and 10-14 cm (mean 12 cm) length of the transplanted hairs.

[CONCLUSION] When coup de sabre is no longer in an active state, hair transplantation is a useful method for cosmetic improvement of the alopecia.
