All implants initiate a foreign-body response that leads to their encapsulation by scar tissue. In order to better understand this encapsulation process and the differences between soft (comfortable) and firm (contracted) breasts, we studied 22 patients who had come in for reaugmentation during a 2-year period. The capsules removed were prepared and measured using a new method. The capsules were (1) removed and stored in physiologic solution until the time of measurement (30 minutes to 2 hours) and (2) measured using a Mitutoyo dial-thickness gauge (MDTG) that employs a uniform pressure of 85 gm. The measurements revealed that soft breasts (Baker 1) have the thinnest scar-tissue capsules, which ranged in thickness from 0.002 to 0.010 inches. Firm breasts yielded the thickest capsules. Baker 3 measured between 0.010 and 0.078 inches thick, and Baker 4 measured between 0.018 and 0.162 inches thick. We also compared the precision of measurement between the MDTG and a standard (screw-type) micrometer by taking a series of readings on a soft, pliable substance (textured silicone rubber).
所有植入物都会引发异物反应，导致其被瘢痕组织包裹。为了更好地理解这种包裹过程以及柔软（舒适）乳房和坚硬（挛缩）乳房之间的差异，我们研究了22名在两年期间前来进行再次隆胸的患者。使用一种新方法对取出的包膜进行制备和测量。包膜的处理方式为：（1）取出后储存在生理溶液中直至测量时（30分钟至2小时）；（2）使用采用85克均匀压力的三丰表盘式测厚仪（MDTG）进行测量。测量结果显示，柔软乳房（贝克1级）的瘢痕组织包膜最薄，厚度在0.002至0.010英寸之间。坚硬乳房的包膜最厚。贝克3级的厚度在0.010至0.078英寸之间，贝克4级的厚度在0.018至0.162英寸之间。我们还通过对一种柔软、柔韧的物质（纹理硅橡胶）进行一系列读数，比较了MDTG和标准（螺旋式）千分尺之间的测量精度。
