There are many indications for breast augmentation, including reconstruction after mastectomy, correction of congenital disorders and cosmetic procedures. The most frequent local complication of this surgery is capsule formation due to fibrosis. The aim of the study was to assess the usefulness of sonoelastography in the evaluation of capsule formation around silicone implants.
The study group included 13 patients aged 20 to 41, who underwent breast augmentation with silicone implants. Their 26 breasts were examined before surgery, 7 and 14 days and a minimum of 8.5 months after surgery. The breast stiffness was assessed with tonometry and shear wave elastography to evaluate elasticity of the breast tissue and capsule formation after surgery.
We assessed the correlation between capsular elasticity measured at successive visits and the Baker scale. There were no significant relationships between any pairs of variables (p > 0.05). We also analyzed the correlation between the time of the follow-up and changes in the tissue elasticity of every region - no significant relationship was found. The greatest decrease in pericapsular elasticity was established in lower and inner quadrants. Moreover, there was a significant difference between the elasticity of the tissue before and 1 week after surgery (p < 0.05) and no significant changes in the elasticity before surgery and at the end of the follow-up.
Sonoelastography is precise in evaluation of capsule formation after breast augmentation. It may show changes that cannot be assessed using palpation.
乳房增大术有多种适应证，包括乳房切除术后的重建、先天性疾病的矫正以及美容手术。该手术最常见的局部并发症是因纤维化导致的包膜形成。本研究的目的是评估超声弹性成像在评估硅胶植入物周围包膜形成中的作用。
研究组包括13例年龄在20至41岁之间接受硅胶植入物乳房增大术的患者。对其26侧乳房在手术前、术后7天、14天以及至少8.5个月后进行检查。通过眼压测量法和剪切波弹性成像评估乳房硬度，以评估术后乳房组织的弹性和包膜形成情况。
我们评估了连续几次随访时测量的包膜弹性与贝克分级之间的相关性。各变量对之间均无显著相关性（p>0.05）。我们还分析了随访时间与每个区域组织弹性变化之间的相关性，未发现显著相关性。包膜周围弹性下降最大的部位是下象限和内象限。此外，手术前与术后1周组织弹性存在显著差异（p<0.05），手术前与随访结束时弹性无显著变化。
超声弹性成像在评估乳房增大术后的包膜形成方面较为精确。它可能显示出触诊无法评估的变化。
