Abstract    Two-stage prosthetic breast reconstruction with initial insertion of a tissue expander is one of the most common methods of breast reconstruction after mastectomy for breast cancer. It offers a "secondary selection" and has high cosmetic stability, and forms the foundation for other breast reconstruction techniques. Breast surgeons should better grasp the technique, make comprehensive consideration from surgical timing, the key points of surgical operation, and the treatments for surgical complications, so as to achieve the best operation effect of two-stage prosthetic breast reconstruction, and effectively improve the patients' quality of life.

摘要： 利用组织扩张器置换假体的两步法植入物重建是乳腺癌术后最常见的重建方式之一，其具有“二次选择”和美容稳定性高的特点，同时也是其他乳腺重建技术的基础。乳腺外科医生应更好地掌握组织扩张器置换假体技术，从假体置换的时机选择、手术操作要点及手术并发症处理等方面进行综合考量，合理规划，以实现乳房植入物两步法重建的最佳手术效果，从而切实提高病人的疗效和生活质量。
