Symmetrization Management in Breast Reconstruction with Implant after Tissue Expansion

目的：探讨组织扩张后使用假体进行乳房再造过程中，可使两侧乳房对称的方法。方法2006年6月至2014年6月，对48例患者行组织扩张后假体乳房再造，在再造过程中采用对称性处理，方法包括：①选择直径与健侧乳房基底直径相近的扩张器，对称位置埋置，下极位置低于对称下皱襞2~3 cm，超量注水扩张；②依据扩张器注水容积，模拟假体容量及健侧乳房的三维摄像数据选择大小、形态适合的假体；③采用包括患侧的自体颗粒脂肪注射移植、背阔肌肌瓣移植、乳头乳晕移位，健侧乳房缩小、假体置入增大、上提固定等对称性修整手术。结果本组患者术后随访6~48个月，平均11.9个月。术后双侧乳房均达到基本对称，患者对再造效果满意。结论对乳房准确的测量，选择合适的扩张器，置入恰当的假体，结合两侧适当的修整，可以获得对称的再造效果。Objective To explore different techniques for bilateral symmetry in breast reconstruction with implant after tissue expansion. Methods From June 2006 to June 2014, 48 patients received breast reconstruction with implant after tissue expansion. The following symmetrization procedures were used during breast reconstruction. (1) Expander was chosen according to controlateral size and was placed 2 to 3 cm lower than controlateral IMF and then over-expand. (2) The implant was chosen according to the expander, the sizer or the data from 3D photography. (3) Ipsolateral fat transfer, latissimus dorsi muscle flap transplantation, NAC transposition, and contralateral breast reduction, mastopexy, augmentation were used for symmetrization. Results All the patients were followed up for 6 to 48 months, mean 11.9 months. Bilateral symmetry were achieved through these procedures and all patients were satisfied with the results. Conclusion Accurate measurement of the breast, the appropriate choice of the expander and implant, and symmetrization procedures of both side are necessary for better symmetry in breast reconstruction.中国科技核心期刊(ISTIC)267-68,9
