AI Technical Summary
Existing cheekbone repositioning techniques suffer from problems such as significant trauma, long recovery period, short-lived effects, and unstable fixation, and cannot effectively address mid-facial aging manifestations such as eye bags, tear troughs, and Indian lines.

This method combines minimally invasive puncture, orbital septum tightening and fixation, SOOF lifting and anchoring, and fat pad mesh ligation with 5-0 non-absorbable polyethylene terephthalate sutures and 21G blunt needles to achieve both minimal invasiveness and strong fixation.
It achieves an anatomical solution to mid-facial aging problems, with a short operation time, stable results, and immediate postoperative repositioning effect. There is no significant swelling or complications, and no risk of fat displacement within 12 months.
