The purpose of this study was to analyze prospectively 50 patients submitted to lower blepharoplasty allocated to two surgical groups at Federal University of São Paulo, between April 2005 and May 2007.
Fifty patients were assigned for interventions into two surgical groups by using random allocation. The SG1 (control group) was composed of 25 patients who were submitted to conservatively standard fat-resection lower blepharoplasty, and routine lateral canthal support. The SG2 (experimental group) was represented by 25 patients submitted to lower blepharoplasty with periorbital fat mobilization and arcus marginalis redrape, and routine lateral canthal support. Preoperative demographic and morphological data from patient charts and standardized photographs obtained before and after surgery were evaluated by an independent observer. Surgical techniques and management of complications were determined from operative reports and clinical notes.
The median follow-up was 395 days (range 364 to 547 days). The mean age was 48.8 years; the population's gender was predominantly female (96%). Analysis of preoperative and postoperative photographs showed that all patients achieved significant improvement. Lateral canthal support was performed in all patients with statistically significant results.
The authors concluded that both procedures are safe and effective, with low complication rates.
本研究的目的是前瞻性分析 50 例于 2005 年 4 月至 2007 年 5 月在圣保罗联邦大学接受下眼睑成形术的患者，将其分为两组。
通过随机分配，将 50 例患者分为两组进行干预。SG1（对照组）由 25 例接受保守标准脂肪切除下眼睑成形术和常规外侧眦支撑的患者组成。SG2（实验组）由 25 例接受眶周脂肪移位和边缘弓重新悬吊的下眼睑成形术和常规外侧眦支撑的患者组成。术前人口统计学和形态学数据来自患者病历和手术前后的标准照片，由独立观察者进行评估。手术技术和并发症的处理根据手术报告和临床记录确定。
中位随访时间为 395 天（范围 364-547 天）。平均年龄为 48.8 岁；患者性别以女性为主（96%）。术前和术后照片的分析显示，所有患者均有显著改善。所有患者均行外侧眦支撑术，结果具有统计学意义。
作者得出结论，两种手术方法均安全有效，并发症发生率低。
