Background: Low follicular donor reserves present a major challenge to successful hair transplantation and patient satisfaction.

Objective: To develop an updated method of harvesting hair follicles in patients with limited donor reserves and to compare the updated methodology with current standards of practice.

Materials and methods: A two part prospective, randomized case control study was conducted to compare the donor site scars of group A (compact tandem line extraction; new method) and group B (scattered extraction; traditional method). Semi-quantitative evaluations of the donor site scars by intervention group were each examined by two dermatologists. Patient satisfaction for each extraction procedure was assessed with a 10 point questionnaire.

Results: The mean number of extracted follicles in groups A and B was 104.60 and 80.33, respectively (group A; p<0.05). These results suggest optimization of the quantity of harvested follicles while utilizing the compact tandem line extraction technique versus standard scattered extraction. Mean patient satisfaction with extraction site cosmesis was 8.83 and 8.20 for group A and B respectively; indicating increased patient satisfaction with compact tandem line technique versus the traditional scattered extraction method (group A; p<0.05).

Conclusion: We found that the compact tandem line harvesting extraction method can yield more follicles that are viable for transplantation than the traditional scattered extraction technique. Furthermore, this novel technique was significantly associated with increased patient satisfaction with the cosmetic outcome of their hair transplant procedure.
