How is forehead augmentation with expanded polytetrafluoroethylene (ePTFE) performed? Experts note that the process is complex, involving both meticulous preoperative planning and precise intraoperative techniques. Below, we detail the surgical procedure for ePTFE forehead augmentation to help prospective patients understand the process.
The specific surgical steps for EPT forehead augmentation are as follows:
① Based on the degree of forehead concavity, facial features, and hairline height, the required augmentation area and volume are pre-determined and outlined. An EPT implant of appropriate size and shape is then designed.
② Forehead incision placement: The incision is designed according to forehead width, positioned either within or outside the hairline.Some experts suggest using 6cm forehead width as a guideline: for foreheads wider than 6cm, the incision is placed along the anterior hairline; for foreheads narrower than 6cm, the incision is made within the scalp.④ Incision of the scalp at the planned site.
⑤ Exposure and dissection of the bony-soft tissue space.
⑥ Implantation of the expanded polytetrafluoroethylene (ePTFE) graft.
⑦ Redraping and fixation of the scalp flap.
⑧ Wound irrigation and scalp closure.
⑨ Postoperative care: Leave negative pressure drainage tubes in place for approximately 1-2 days. Apply external pressure bandaging to the incision site for 5-7 days. Administer routine anti-inflammatory treatment as scheduled. Sutures are typically removed around 10 days post-op.
