Implant size selection in breast augmentation patients is one of many variables to be determined before surgery. Few methods exist today that allow the patient to participate in this process and accurately determine optimal size. The authors describe a simple method of preoperative sizing using silicone implant samples.
A total of 567 patients underwent breast augmentation: 297 had surgery before implementation of preoperative sizing and 270 patients were sized preoperatively. Sizing consisted of fitting the patients with various size silicone implants in a larger bra at least twice before surgery to determine desired size. Surveys were sent to both groups to inquire about overall satisfaction, how many preferred a different size postoperatively, and how many ultimately underwent size change surgery.
One hundred two responses (34.3 percent) were obtained from the control group and 142 (52.6 percent) were obtained from the sized group. Sized patients received smaller implants (average, 276.6 cc nonsized versus 246.4 cc sized; p < 0.001). Four patients (1.4 percent) in the control group underwent a size change procedure compared with none in the sized group. In the sized cohort, 69 percent believe they are the size that the process predicted, 21 percent are smaller, 9 percent are larger, and 1 percent did not answer the question.
Sized patients were more satisfied than controls and fewer were interested in having a different size implant postoperatively. Sized patients indicated that preoperative sizing was both helpful and reasonably accurate in predicting final breast size.
在进行隆胸手术前，需要确定许多变量，其中之一是植入物的大小。目前几乎没有方法可以让患者参与到这个过程中，并准确确定最佳的大小。作者描述了一种使用硅酮植入物样本进行术前测量的简单方法。
共有 567 名患者接受了隆胸手术：297 名患者在实施术前测量之前接受了手术，270 名患者进行了术前测量。测量方法是让患者在手术前至少两次在较大的胸罩中试戴各种大小的硅酮植入物，以确定所需的大小。向两组患者发送了调查问卷，询问他们的总体满意度、有多少人术后更喜欢不同的尺寸，以及最终有多少人接受了尺寸变化手术。
对照组收到了 102 份（34.3%）回复，而测量组收到了 142 份（52.6%）回复。测量组的患者接受了较小的植入物（平均，未测量组为 276.6cc，测量组为 246.4cc；p<0.001）。对照组中有 4 名患者（1.4%）进行了尺寸变化手术，而测量组中没有。在测量组中，69%的患者认为他们的尺寸与预测的尺寸相符，21%的患者认为他们的尺寸更小，9%的患者认为他们的尺寸更大，1%的患者没有回答这个问题。
与对照组相比，接受了测量的患者更满意，并且术后对不同尺寸植入物感兴趣的患者更少。接受了测量的患者表示，术前测量既有助于他们的决策，又能合理地准确预测最终的乳房尺寸。
