Abstract

Follicular unit excision (FUE) graft dissection has become the dominant method of donor harvesting globally, however, only a percentage of donor hair can be excised inside the safe donor area before visible donor thinning occurs. Compared to linear strip excision (LSE) where all follicular units inside the harvested ellipse of hair are used, FUE poses substantial limitations for lifetime graft yield and, therefore, cosmetic coverage in patients with advanced pattern hair loss. This paper reviews how combining the donor harvesting methods of FUE and LSE has been shown to optimize graft yield while minimizing the risk of donor depletion from overharvesting. It then describes a surgical technique called FUE-Linear Ellipse (FUE-LE) where FUE dissection of grafts inside a demarcated linear ellipse eliminates the need for a large dissection team which has posed a barrier for many new practices that offer both the donor harvesting methods. For practices that currently offer only FUE, the addition of the LSE method by the modified FUE-LE technique is possible without specialized staff training or associated equipment costs. In this paper, surgery practices that have adopted this technique will report on their experiences. Hair restoration surgeons are encouraged to provide both methods of donor harvesting (FUE and LSE using FUE-LE) in order to optimize graft yield for patients and avoid long-term donor depletion. Based on limited experience, it appears the technique of FUE-LE will help achieve this goal.
