: Follicular Unit Excision (FUE) graft dissection has become the dominant method of donor harvesting globally, however, only a percentage of donor hairs can be excised inside the safe donor area (SDA) 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 life- time graft yield and, therefore, cosmetic coverage in patients with advanced pattern hair loss, especially when baseline density is average. 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. The latter risk increases with aggressive excision density using FUE. However, the LSE approach has had the drawback of requiring a team of assistants for microscopic graft dissection, usually between four and six specially trained assistants. Increasingly clinics have avoided the time and expense of staff and training by simply not offering the LSE method.
This chapter 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. Following FUE of hair inside the demarcated linear ellipse, the harvested ellipse is excised. Any remaining follicular units can be dissected by one or two assistants, and the empty ellipse discarded. For clinics already offering LSE, this technique reduces the dependency on specially trained graft dissectors. For practices that currently offer only FUE, the addition of the linear strip excision (LSE) method is possible without specialized staff training or associated equipment costs. FUE-LE allows clinics to combine donor harvest options to optimize graft yield, critical for patients with advanced pattern hair loss, and minimizes their risk for donor depletion while reducing costs of and dependency on large teams of graft dissectors.
