Our profession has not decided if it is better to incise parallel or perpendicular (at an angle) to hair follicles when performing a brow lift or a face lift. Thirty patients had one side incised parallel and the other side incised perpendicular to hair follicles. Neither the patients nor the examiners knew how each side was incised. By comparing the invisibility, the nonlinearity, the absence of hypopigmentation, and the abundance of hair into and in front of the scar, we obtained statistical proof that if we incised perpendicular to hair follicles (to preserve the deep follicles in the proximal flap), scars were better in 95 percent of patients.
在进行提眉术或面部提升术时，我们这个行业尚未确定沿着毛囊平行切开还是垂直（成一定角度）切开效果更好。30名患者一侧沿着毛囊平行切开，另一侧垂直于毛囊切开。患者和检查者都不知道每一侧是如何切开的。通过比较切口的隐蔽性、非直线性、无色素沉着以及瘢痕内和瘢痕前方毛发的浓密程度，我们获得了统计学证据，即如果垂直于毛囊切开（以保留近端皮瓣中的深部毛囊），95%的患者瘢痕效果更好。
