To evaluate and quantify the increase in lower eyelid tension (stress) after endoscopic forehead/midface-lift in a cohort of patients with normal lower eyelid function preoperatively.
A prospective nonrandomized study was conducted at a private facial plastic surgery practice and ambulatory surgical center on 22 patients who underwent subperiosteal endoscopic forehead/midface-lift from October 2000 to June 2002. Patients were evaluated preoperatively, 4 to 6 months postoperatively, and approximately 12 months postoperatively.
Compared with preoperative lower eyelid tension, there was a 4- to 5-fold increase in lower eyelid tension at 3 and 5 mm of distraction immediately after the operation. Four to 6 months after the operation, lower eyelid tension decreased but was still 2 to 3 times that of preoperative values. Twelve-month measurements for the 15 patients who remained in the study (the other 7 patients were lost to follow-up or refused to have measurements taken) showed that lower eyelid tension was 1.7 to 1.9 times preoperative values.
Our results show that lower eyelid tension increases following endoscopic forehead/midface-lift and that this increased tension is long lasting and quantifiable 12 months after surgery.
评估并量化一组术前下睑功能正常的患者在内镜下前额/中面部提升术后下睑张力（应力）的增加情况。
在一家私立面部整形手术诊所和门诊手术中心对2000年10月至2002年6月期间接受骨膜下内镜前额/中面部提升术的22例患者进行了一项前瞻性非随机研究。在术前、术后4至6个月以及术后约12个月对患者进行评估。
与术前下睑张力相比，术后立即在3毫米和5毫米牵拉时，下睑张力增加了4至5倍。术后4至6个月，下睑张力下降，但仍为术前值的2至3倍。对留在研究中的15例患者（其他7例患者失访或拒绝测量）进行的12个月测量显示，下睑张力为术前值的1.7至1.9倍。
我们的结果表明，内镜下前额/中面部提升术后下睑张力增加，且这种增加的张力在术后12个月是持久且可量化的。
