Construction of a Hair Implantation Needle Using Injection Needles and Assessment of its Efficiency Compared with Other Planting Methods.

INTRODUCTION: Hair transplantation surgery requires the efficient completion of hair follicles and thus appropriate hair implantation needles. The objectives of this study were to evaluate the effectiveness and feasibility of self-made hair implantation needles using injection needles and evaluate the speed of different hair implantation methods. METHODS: Four patients were randomly assigned to four groups. A gem knife pre-punching planting method was used for the patient in Group A, while Group B received immediate implantation after punching with ordinary injection needles, Group C was treated with synchronized punching and planting using hair implanters, and Group D was treated with a self-made hair implantation needle. The speed of the different implantation methods for single and double hair follicles and the differences between the planting of single and double hair follicles were assessed. RESULTS: Group D was found to have the fastest hair planting speed for both single and double hair follicles, followed by Groups C and A, with the slowest speed observed in Group B. Groups A and B were associated with significantly lower speeds of double hair planting than single hair planting, There was no significant difference between Groups C and D. CONCLUSIONS: The self-made hair implantation needle is a novel and efficient tool for synchronized punching and planting. It has a faster planting speed and does not require assistance.

The Training and Application of Silicone Products in Eyebrow Transplantation Simulation.

BACKGROUND: Because the structure of eyebrows is complicated, students need a lot of practice to become familiar with the distribution pattern of eyebrow hair. OBJECTIVES: The current study was designed to investigate training methods for eyebrow design and planting practice before eyebrow hair transplantation to improve planting quality. METHODS: Twelve surgical students were selected. The 6 students in the experimental group had never performed eyebrow transplantation surgery, whereas the 6 in the control group had experience of the procedure. Students in both groups received theoretical and simulated eyebrow hair transplantation instruction. Students were required to master standard eyebrow transplantation. The results of the experimental group and the control group were compared before and after training. RESULTS: The results revealed that the overall results of the experimental and control groups significantly improved compared with before training (P < .05). After theoretical training, 2-dimensional simulation training, and 3-dimensional simulation training, eyebrow shape, symmetry, hair angle, and density after the 3-dimensional simulation training were statistically significantly improved (P < .05). There was no statistically significant difference, and the students in the control group did not demonstrate any improvement in their capacity to arrange the eyebrows or shape them symmetrically. After training, however, the angle and density of the hair substantially improved. CONCLUSIONS: The experimental group's technical ability in simulated eyebrow planting significantly improved. The present study demonstrated that the students could develop their skills and get closer to the level of surgeons with experience in eyebrow transplant surgery by integrating theoretical lectures with practiced procedures.
