Although the follicular unit excision/extraction (FUE) is regarded an easy procedure to perform, however, there are various factors which affect the outcome. The hair transection is dependent of various factors and the donor site characteristics affect largely.
To know the difference in transection rate on various areas of scalp during FUE.
The study was conducted in 10 patients undergoing FUE after obtaining informed consent. In each patient, 1 row was marked with intervening 1 cm . The row contained five boxes of 1 cm . Harvesting of FUs was performed using 0.9 mm serrated punch. The procedures were performed with the patient in supine position with the surgeon sitting on head side. The harvested FUs were checked under microscope. Any transection was calculated. All the data was collected and analyzed statistically.
The total number of FUs and hair were more in center zone as compared to the sides. Whereas, the transection rate was lowest in the mid-occipital zone as compared to the sides. Similarly, the FUs: hair ratio was more in the sides 1:1.85 as compared to 1:1.62 in central zone. The right and left sides also showed some variations. The transection was more on right side (17.7%) of the patient as compared to the left side (16.3%) CONCLUSION: The hair transection was more on sides than in the mid-occipital area.
尽管毛囊单位切除/提取术（FUE）被认为是一种易于实施的手术，但仍有多种因素会影响其效果。毛发横断受多种因素影响，供区特征的影响很大。
了解FUE过程中头皮不同区域横断率的差异。
本研究在10例获得知情同意后接受FUE的患者中进行。在每位患者的头皮上，每隔1厘米标记一排。每排包含五个1厘米见方的区域。使用0.9毫米的锯齿状打孔器采集毛囊单位。手术过程中患者仰卧，外科医生坐在头部一侧。采集的毛囊单位在显微镜下检查，计算任何横断情况。收集所有数据并进行统计学分析。
与两侧相比，中心区域的毛囊单位和毛发总数更多。然而，与两侧相比，枕骨中部区域的横断率最低。同样，两侧的毛囊单位与毛发比例更高，为1:1.85，而中心区域为1:1.62。左右两侧也存在一些差异。患者右侧的横断率（17.7%）高于左侧（16.3%）。结论：两侧的毛发横断情况比枕骨中部区域更严重。
