背阔肌肌皮瓣联合假体在乳腺癌术后二期乳房再造中的应用

Application of Latissimus Dorsi Myocutaneous Flap with Breast Implant in Delayed Breast Reconstruction after Mastectomy

目的探讨背阔肌肌皮瓣联合假体植入在乳腺癌术后二期乳房再造术中的临床应用。方法 2009年至2013年,共8例乳腺癌术后年轻患者接受二期乳房再造手术。术前以排水法测定健侧乳房体积,根据患者健侧乳房形状、大小及背部组织情况,设计胸背部供区皮瓣,术中测量移植皮瓣的容积,然后根据健侧乳房和移植皮瓣的容积差,选择大小合适的乳房假体,将假体埋植于背阔肌-胸大肌后间隙,利用背阔肌肌皮瓣移植联合乳房硅胶假体进行二期乳房再造。结果本组患者术后随访6个月至4年,再造乳房外形较佳,效果满意,供区无明显并发症。结论对于年轻有生育要求的乳腺癌术后乳房缺失患者,健侧乳房较大,利用背阔肌肌皮瓣联合假体进行乳房再造,可取得良好的手术效果。

Objective To explore the application of latissimus dorsi myocutneous flap and breast implant in delayed breast reconstruction surgery after mastectomy. Methods From 2009 to 2013, 8 cases received delayed breast reconstruction operation after mastectomy. The breast volumetry measurement technique was used to determine the mass of the breast preoperatively, then the donor flap was designed at the chest-back region according to the condition of the dorsal skin and the shape of the contralateral breast. The mass of graft flap was measured intraoperatively, then the suitable implant was selected based on the difference between the volume of the contralateral breast and the graft flap. The breast implant was then placed in the interspace between the latissimus dorsi muscle and the pectoralis major muscle to reconstruct the breast（secondary phase）. Results All patients were followed up for 6 months to 4 years. The overall appearance of the constructed breast were satisfactory, no significant complications were observed in the donor region. Conclusion For young patients of breast cancer with relatively large breast volume, who also have fertility demands, the coalition usage of the latissimus dorsi myocutaneous flap and breast implant in breast reconstruction is proved to have ideal operative results.
