Background:
An obvious saggy tendency was observed in the expanded flaps from mid-facial reconstruction and resulted in an unsatisfactory postoperative cosmetic outcome. At the time of this writing, the authors introduced a novel technique of mid-face lifting to correct the phenomenon by suspending the expander capsule.
Methods:
From September 2018 to August 2023, 11 patients who had undergone our mid-face lifting technique were enrolled in our study. The expanded flap was divided into 2 layers during the surgical procedure. The upper layer, which consists of the skin and the subcutaneous layer, was lifted, and the lower layer, consisting of the expander capsule and SMAS system, was left at the base. Then a capsular flap was lifted from the base and folded upward to lift the reconstructed mid-face. The capsular flap was fixed in the temporal or mastoid region when the saggy tendency was corrected, and the mid-facial contour became symmetric. Finally, the upper layer was trimmed and fixed at the base. Facial movements were restricted after the surgery.
Results:
The saggy tendency of all the expanded flaps was corrected, and the mid-facial symmetry was rebuilt immediately after the surgery. The effect were long-lasting at 3 months to 2 years of follow-ups. No serious postoperative complications occurred. The patients or their legal guardians were satisfied with the esthetic improvement.
Conclusion:
Reconstructed mid-face lifting with capsular flap was an effective and reliable way to correct the saggy tendency of a mid-facial expanded flap and rebuilt the mid-facial symmetry.

Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
