经脐孔缘切口置入充注式生理盐水假体隆乳术

Transumbilical breast augmentation with insertion of saline-filled breast implants

目的探讨经脐孔缘切口行充注式生理盐水假体隆乳术的手术方法，为隆乳术提供新切口选择。方法沿脐孔缘切口，采用特制专用器械分离皮下隧道至乳房下皱襞，然后穿进胸大肌后间隙，分离假体放置空间，先置入扩张器，充注生理盐水后，调整乳房形态以及扩张器位置。然后取出扩张器，更换为充注式生理盐水乳房假体而完成手术。结果采用经脐孔缘切口行充注式生理盐水假体隆乳术者，均获得了良好的手术效果，无感染、血肿、假体渗水、BakerⅢ或Ⅳ级纤维囊挛缩等并发症发生。结论采用生理盐水充注式乳房假体，经脐孔缘切口可以完成胸大肌下隆乳术，增加了隆乳手术切口的选择范围。

Objective To evaluate the surgical technique and procedures of transumbilical breast augmentation with an inverse U-shape incision and insertion of saline-filled breast implants. Methods With specialized instruments, the subcutaneous tunnel was undermined to the inframammary crease after inverse U incision made along the umbilical border. The subpectoral space was dissected with a dissector after the advancement of obturator across the inframammary crease. The expander was inserted into the subpectoral pocket to be filled to obtain the high degree of symmetry of the breasts. Finally, the previously prepared implants were inserted after the expander deflated and removed. Results All patients gained satisfactory results with no complications, such as hematoma, infection, implant deflation and Baker III or IV capsular contracture. Conclusions Breast augmentation could be performed through umbilical incision with the usage of saline-filled breast implant. This is an alternative of incisions in breast augmentation.
