By means of an ultrasonic technique, skin thickness was measured in 13 women subjected to mammary reconstruction by tissue expansion. Measurements were performed the day before introduction of the expander, after the last inflation, the day before introduction of the permanent implant, and at 2 weeks and 6 months after this operation. Five patients had their expanders inflated every day (rapid expansion), and 8 patients, once a week (slow expansion). A decrease in skin thickness during the inflation period was recorded, and this decrease was permanent even 6 months after the second operation. After exchange of the expander for a permanent implant, there was a transient statistically significant increase in skin thickness. There was no statistical difference between the groups of rapid and slow expansion.
通过超声技术，对13名接受组织扩张法乳房重建的女性进行了皮肤厚度测量。测量时间分别为扩张器植入前一天、最后一次注水后、永久性植入物植入前一天以及手术两周和六个月后。5名患者每天对扩张器进行注水（快速扩张），8名患者每周注水一次（缓慢扩张）。记录到注水期皮肤厚度有所下降，且即使在第二次手术后6个月，这种下降仍然持续存在。将扩张器更换为永久性植入物后，皮肤厚度出现短暂的统计学显著增加。快速扩张组和缓慢扩张组之间没有统计学差异。
