To compare postoperative forehead and scalp sensation for the "open" brow-lift (OBL) (coronal and trichophytic) with that of the endoscopic brow-lift (EBL).
A controlled outcome evaluation study was designed to objectively (mechanoceptive and thermoceptive) and subjectively (visual analog scale) test forehead and scalp sensation in a group of patients having undergone or scheduled to undergo either OBL or EBL in a single, private facial plastic surgery clinic. Prospectively enrolled participants were tested at defined intervals (A, preoperation; B,1-2 weeks after; C, 4-6 weeks after; D, 12-14 weeks after; and E, 24-26 weeks after). To provide extended follow-up data (≥6 months), patients returning for scheduled follow-up examination who had already undergone either OBL or EBL were subjected to the same test battery. For statistical analysis of the extended follow-up data, the participants were divided into 2 groups (F, 6-18 months; and G, >18 months). The null hypothesis was that there would be no measurable difference between the OBL and the EBL groups related to postoperative forehead and scalp sensation.
Twenty-one individuals (EBL, n = 11; OBL, n = 10) were enrolled prospectively. All showed normal objective and subjective values preoperatively. While both groups objectively and subjectively demonstrated decreased sensation over follow-up, the OBL group showed statistically significant decrement in objective scalp sensitivity at times B, C, and D vs the EBL group. Subjectively, the OBL group felt less sensitive than the EBL group at times C and D. Those relationships disappeared at time E. Fifty-eight individuals were retrospectively enrolled. At time F (EBL, n = 16; OBL, n = 10), an objective and subjective difference was again observed with the OBL group demonstrating less scalp sensitivity vs the EBL group. At time G (EBL, n = 20; OBL, n = 12), this difference was no longer observed.
We reject the null hypothesis and state that there is a measurable, statistically significant difference between the studied groups related to postoperative forehead and scalp sensation and that those observed differences are objective and subjective in nature as well as time dependent. However, almost no patients (57 of 58), irrespective of the technique used for their brow-lift, viewed their experienced forehead and/or scalp numbness to have been significant enough to deter them from undergoing the surgery again.
比较“开放式”提眉术（OBL，冠状切口和毛发移植切口）与内镜提眉术（EBL）术后前额和头皮的感觉。
设计一项对照结局评估研究，在一家私立面部整形手术诊所中，对一组已接受或计划接受OBL或EBL的患者进行前额和头皮感觉的客观（机械感觉和温度感觉）和主观（视觉模拟量表）测试。对前瞻性纳入的参与者在规定的时间间隔进行测试（A，术前；B，术后1 - 2周；C，术后4 - 6周；D，术后12 - 14周；E，术后24 - 26周）。为了提供延长的随访数据（≥6个月），对已接受OBL或EBL并返回进行定期随访检查的患者进行相同的测试。对于延长随访数据的统计分析，参与者被分为两组（F，6 - 18个月；G，>18个月）。零假设是OBL组和EBL组在术后前额和头皮感觉方面没有可测量的差异。
前瞻性纳入21名个体（EBL组11名；OBL组10名）。所有患者术前客观和主观值均正常。虽然两组在随访期间客观和主观上均显示感觉减退，但与EBL组相比，OBL组在B、C和D时间点客观头皮敏感性有统计学显著下降。主观上，OBL组在C和D时间点感觉比EBL组不敏感。这些差异在E时间点消失。回顾性纳入58名个体。在F时间点（EBL组16名；OBL组10名），再次观察到客观和主观差异，OBL组头皮敏感性低于EBL组。在G时间点（EBL组20名；OBL组12名），这种差异不再观察到。
我们拒绝零假设，并指出在研究组之间，与术后前额和头皮感觉相关存在可测量的、统计学显著的差异，并且观察到的差异在性质上是客观和主观的，并且与时间有关。然而，几乎没有患者（58名中的57名），无论其提眉术采用何种技术，认为他们经历的前额和/或头皮麻木严重到足以阻止他们再次接受手术。
