BACKGROUND: 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. METHODS: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. RESULTS: 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. CONCLUSION: The authors concluded that both procedures are safe and effective, with low complication rates.
