The ability to exercise more easily and weight loss are often cited benefits of reduction mammaplasty. However, measured weight outcomes after this common procedure are lacking. The purpose of this study was to measure body mass index (BMI) changes in an otherwise healthy adolescent sample after bilateral breast reduction.
We retrospectively reviewed the records of patients aged 12-21 years who underwent reduction mammaplasty at our institution between 2007 and 2013, with a minimum postoperative follow-up time of 1 year. Charts were reviewed for preoperative and postoperative height and weight, amount of breast tissue resected, and medical comorbidities. No formal nutritional support or weight loss program was instituted before or after surgery.
Eighty patients meeting eligibility criteria were identified. The mean follow-up time was 2.0 ± 1.0 years. Mean postoperative BMI did not differ significantly from mean preoperative BMI (27.8 ± 7.1 kg/m(2) vs. 27.3 ± 6.4 kg/m(2)). However, among overweight and obese patients, a significant gain in preoperative to postoperative BMI was observed, on average (p = .019). Twelve (22.2%) of these patients increased their BMI by at least 10% after reduction mammaplasty. Although approximately one third (37%) of overweight/obese patients decreased their BMI, only 5.6% decreased BMI by at least 10%.
We found no significant difference between mean preoperative and postoperative BMI among patients who underwent reduction mammaplasty. Our results suggest that although reduction mammaplasty may facilitate exercise and help some patients lose weight, meaningful postoperative weight loss without additional support is rare.
更轻松地进行锻炼的能力和体重减轻常常被认为是缩乳术的益处。然而，对于这种常见手术术后的体重测量结果却很缺乏。本研究的目的是测量双侧乳房缩小术后健康青少年样本的体重指数（BMI）变化。
我们回顾性分析了2007年至2013年在我院接受缩乳术的12至21岁患者的记录，术后随访时间至少为1年。查阅病历以获取术前和术后的身高、体重、切除的乳腺组织量以及合并症。手术前后均未实施正式的营养支持或减肥计划。
确定了80名符合入选标准的患者。平均随访时间为2.0±1.0年。术后平均BMI与术前平均BMI无显著差异（分别为27.8±7.1kg/m²和27.3±6.4kg/m²）。然而，在超重和肥胖患者中，术前至术后BMI平均有显著增加（p = 0.019）。这些患者中有12名（22.2%）在缩乳术后BMI至少增加了10%。尽管约三分之一（37%）的超重/肥胖患者BMI有所下降，但只有5.6%的患者BMI下降至少10%。
我们发现接受缩乳术的患者术前和术后平均BMI无显著差异。我们的结果表明，虽然缩乳术可能有助于锻炼并帮助一些患者减轻体重，但在没有额外支持的情况下，术后有意义的体重减轻很少见。
