Enhanced Transconjunctival Lower Blepharoplasty: A Novel Method for Intraorbital Fat Transposition and Stabilization

The evolution of lower blepharoplasty has shifted from simply removing of orbital septum fat to smoothing of the lid-cheek junction through fat repositioning. This paper adopts a novel technique to transpose and stabilize intraorbital fat during transconjunctival lower blepharoplasty. The tear trough and nasal alar base were filled to correct the pouch while ensuring the blood supply of the fat flap.

Between September 2019 and June 2022, 104 patients aged between 22 and 49 who underwent bilateral fat flap transposition-nasal alar base filling lower blepharoplasty were selected. The surgical results were assessed by non-operative plastic surgeons according to the Hirmand grading system. Moreover, a self-satisfaction survey was conducted and patients were followed up for at least 6 months to evaluate any complications and surgical outcomes. A high-frequency ultrasound imaging system was used to assess the degree of filling of the tear trough and nasal alar base.

All 104 patients were followed up for at least 6 months. The postoperative Hirmand grade was 0 for 96 out of 104 (92.3%) patients. In terms of self-satisfaction assessment, there were 92 out of 104 (88.5%) patients reported satisfaction. Dermatologic ultrasound showed no obvious gaps 6 months after surgery.

Transconjunctival fat flap transposition combined with nasal alar base filling during lower blepharoplasty has been shown to have a positive postoperative effect and high patient satisfaction. This procedure can preserve the blood supply of the fat flap, reduce the rates of fat absorption and denaturation, and improve facial contour, resulting in a satisfactory repairing effect.
