This retrospective study evaluated aging and rupture of silicone gel breast implants in 31 women. The implants were removed at a large multispecialty clinic from 1987 to 1990. The implants ranged in age from 1 to 17 years. Of the 51 implants removed, 27 were ruptured, 7 were leaking, and 17 were in good condition. Common reasons for implant removal were discomfort, firmness, or a mass adjacent to a ruptured implant. Injury to the breast (trauma or mammography) led to a removal in only 4 patients. Closed capsulotomies were common in both ruptured and intact groups. The number of intact implants declined over time. All implants older than 10 years were leaking or ruptured. There was a positive correlation between the duration of implantation time and the number of ruptured and leaking implants.
这项回顾性研究评估了31名女性硅胶乳房植入物的老化和破裂情况。这些植入物于1987年至1990年在一家大型多专科诊所被取出。植入物的使用年限为1至17年。在取出的51个植入物中，27个破裂，7个渗漏，17个状况良好。取出植入物的常见原因是不适、变硬或破裂植入物附近出现肿块。仅4例患者因乳房损伤（外伤或乳房X线摄影）而取出植入物。在破裂组和完整组中，闭合性包膜切开术都很常见。完整植入物的数量随时间减少。所有使用年限超过10年的植入物都出现了渗漏或破裂。植入时间长短与破裂和渗漏植入物的数量之间存在正相关。
