Methods Forty patients with androgenetic alopecia were treated with hair-transplant surgery. During the transplantation operation, manual punch and ZMY-1 hair transplantation system were used respectively to make holes on bilateral recipient bald areas on the forehead of patiens. Data were statistically analyzed by paired samples t test and Wilcoxon rank sum test with the software SPSS 18.0. Results The time taken to make 100 holes was ��2.22 ± 0.71�� minutes by ZMY-1 hair transplantation system, significantly shorter than that by manual punch ����11.33 ± 2.68�� minutes, t = 6.78, P < 0.01��. There was no statistical difference in the occurrence of postoperative complications, such as bleeding, oozing of blood, congestion and edema. On day 10 after the operation, the average survival rate of transplanted tissue was 95.00% for ZMY-1 hair transplantation system and 94.83% for manual punch ��Z =0.853, P > 0.05��. Conclusion The ZMY-1 hair transplantation system could markedly increase the efficiency of making holes in hair-transplant surgery with a favorable safety and reliability. ��Key words�� Hair; Transplantation; Alopecia; Surgical procedures, operative
