Abstract：
This study was conducted to see if better scar results could be obtained by administering botulinum neurotoxin type A (BoNTA) injection and W-plasty incision for preventing rhytidectomy scar.
All patients underwent extended deep-plane rhytidectomy in two groups. Group 1 had a straight incision line, and BoNTA was not given. Group 2 was injected with W-plasty and BoNTA. Photos were taken before surgery and twelve months after surgery. Two aesthetic surgeons analyzed the results using MSS, MSRS, and SBSES. Interrater reliability was measured using the intraclass correlation coefficient (ICC).
Forty-nine patients were included in the study. Group 1 (Straight incision, No BoNTA) had 26, and Group 2 (W-plasty, BoNTA) had 23 patients. The interrater reliability in Group 1 was excellent for MSS (ICC, 0.957 [0.904-0.981]), and good in two of the interrater reliability measures (ICCs, 0.897 [0.769-0.954] for MSRS, and 0.821 [0.605-0.919] for SBSES). Interrater reliability in Group 2 was good in two out of three measures (ICCs, 0.760 [0.423-0.899] for MSS, 0.746 [0.392-0.893] for MSRS, and 0.851 [0.654-0.937] for SBSES). There was a significant statistical difference between Group 1 and Group 2, showing that Group 2 has superior outcomes (MSS, 6.596 ± 1.569 vs. 5.435 ± 0.590, P = 0.001; MSRS, 4.346 ± 0.967 vs. 3.652 ± 0.510, P = 0.003; SBSES, 3.788 ± 0.695 vs. 4.261 ± 0.541, P = 0.012).
Analyzed by three dedicated scar assessments, better results were obtained through combining W-plasty and BoNTA injections, so it is expected to be a useful method for improving scars.

摘要：
进行这项研究是为了观察通过施用A型肉毒杆菌神经毒素（BoNTA）注射和W-成形术切口以防止除皱术疤痕是否可以获得更好的疤痕结果。
两组患者均行深平面除皱术。第1组有一条直线切口，没有给BoNTA。第2组注射W-成形术和BoNTA。手术前和手术后12个月拍摄照片。两名美容外科医生使用MSS分析了结果，MSRS,和SBSES。使用组内相关系数(ICC)测量评分者间可靠性。
49名患者被纳入研究。第1组(直切口，没有BoNTA)有26例，第2组(W-成形术，BoNTA）有23名患者。第1组的评分者间可靠性对于MSS来说是极好的(ICC，0.957[0.904-0.981])，在两项评估者间可靠性措施(ICC，0.897[0.769-0.954]对于MSRS，SBSES为0.821[0.605-0.919]）。第2组的评分者间可靠性在三项措施中有两项良好(ICC，0.760[0.423-0.899]适用于MSS，0.746[0.392-0.893]适用于MSRS，和0.851[0.654-0.937]用于SBSES)。第1组和第2组之间存在显着统计学差异，表明第2组具有更好的结局（MSS，6.596±1.569vs.5.435±0.590，P=0.001；MSRS，4.346±0.967vs.3.652±0.510,P=0.003;SBSES,3.788±0.695vs.4.261±0.541,P=0.012)。
通过三个专门的疤痕评估进行分析，通过结合W-成形术和BoNTA注射获得了更好的结果，因此，它有望成为改善疤痕的有用方法。
