To determine if upper eyelid blepharoplasty causes eyebrow position to drop in a cosmetic surgery population.
Retrospective, observational study. A treatment group that underwent upper eyelid blepharoplasty was compared with a matched control group that did not undergo the surgery.
Private facial plastic surgery practice. All surgery was performed at an ambulatory surgical facility on an outpatient basis.
A total of 82 patients (164 eyes) were included in this study: 54 (8 men and 46 women; average age, 46.8 years) in the treatment group and 28 (6 men and 22 women; average age, 43.8 years) in the control group. The treatment group was chosen in a retrospective fashion to include only those patients (1) for whom preoperative and postoperative photographs were available and (2) who had undergone upper eyelid blepharoplasty by the senior author (F.M.K). These patients underwent no other procedures, either before or during the time span between the photographs, that could affect eyebrow position. The control group consisted of patients who had an available set of matching photographs taken over time. These patients did not undergo blepharoplasty or any other procedure that could alter eyebrow position between their initial and final photographs.
Upper eyelid blepharoplasty performed by the senior surgeon (F.M.K.). The surgical technique was identical in all cases.
The change in eyebrow height reflected as a percentage of the pretreatment height. Results are based on measurements taken from standardized photographs.
Original treatment and control groups of 108 and 56 eyes, respectively, were restricted to a smaller number to create similar populations for comparison. Therefore, 40 eyes in the treatment group were matched with 28 eyes in the control group to control for the duration between measurements. A t test found no significant difference (P = .94) in eyebrow height between patients who had a blepharoplasty and those who had not.
In a cosmetic surgery population, upper eyelid blepharoplasty does not cause a lowering of the eyebrow.
确定在整容手术人群中，上睑成形术是否会导致眉位下移。
回顾性观察研究。将接受上睑成形术的治疗组与未接受该手术的匹配对照组进行比较。
私立面部整形手术诊所。所有手术均在门诊手术设施中作为门诊手术进行。
本研究共纳入82例患者（164只眼）：治疗组54例（8例男性和46例女性；平均年龄46.8岁），对照组28例（6例男性和22例女性；平均年龄43.8岁）。治疗组以回顾性方式选取，仅纳入那些（1）有术前和术后照片的患者，以及（2）由资深作者（F.M.K.）进行过上睑成形术的患者。这些患者在照片拍摄之前或拍摄期间未进行过其他可能影响眉位的手术。对照组由随时间拍摄了一组匹配照片的患者组成。这些患者在最初和最终照片之间未进行过睑成形术或任何其他可能改变眉位的手术。
由资深外科医生（F.M.K.）进行上睑成形术。所有病例的手术技术相同。
眉高度的变化以术前高度的百分比表示。结果基于从标准化照片中获取的测量值。
最初治疗组和对照组分别有108只眼和56只眼，为创建相似的可比人群而减少至较小数量。因此，治疗组的40只眼与对照组的28只眼匹配，以控制测量之间的时间间隔。t检验发现，接受睑成形术的患者与未接受睑成形术的患者之间，眉高度无显著差异（P = 0.94）。
在整容手术人群中，上睑成形术不会导致眉位降低。
