OBJECTIVE
This study aims to establish the concept of invalid extraction rates in follicular unit extraction and evaluate its clinical value.
METHODS
The present study involved 30 patients with alopecia. Three young surgeons (nominated A, B, and C) each performed follicular unit extraction on a randomly selected portion of the donor site of each patient for ten minutes. The outcomes were separately recorded and calculated, and converted to an invalid extraction rate for each surgeon using the formula, "invalid extraction rate = 1 - successfully extracted follicular units/actually extracted units × 100%."
RESULTS
The follicular unit invalid extraction efficiency of each surgeon gradually declined. The average efficiency level of surgeon B was evaluated as excellent, while the levels of surgeons A and C were evaluated as good.
CONCLUSION
With experience, surgeons can speed up the process of follicular unit extraction and gradually increase performance quality through both extraction speed and success rate.
目的
本研究旨在建立毛囊单位提取中无效提取率的概念并评估其临床价值。
方法
本研究纳入30例脱发患者。三名年轻外科医生（分别命名为A、B和C）对每位患者供区的随机选择部位进行10分钟的毛囊单位提取。分别记录和计算结果，并使用公式“无效提取率=1 - 成功提取的毛囊单位数/实际提取的单位数×100%”为每位外科医生换算出无效提取率。
结果
每位外科医生的毛囊单位无效提取效率逐渐下降。外科医生B的平均效率水平被评为优秀，而外科医生A和C的水平被评为良好。
结论
随着经验的积累，外科医生可以加快毛囊单位提取过程，并通过提取速度和成功率逐步提高操作质量。
