Development of a Uterosacral Ligament Suspension Rat Model
Published on: August 17, 2022
Background:
Retaining ligaments must be fully released for effective soft-tissue mobilization during sub-superficial musculoaponeurotic system (SMAS) facelifts. Standard deep temporal fascia and lateral SMAS fixation techniques may fail earlier than anticipated, which may cause a relapse of facial aging signs. Reconstruction of retaining ligaments was previously proposed to enhance facelift fixation.
Objectives:
The author sought to assess the effect of their ligament reconstruction technique on early relapse rates and complication rates.
Methods:
This study was a comparative analysis of 188 consecutive facelift cases where retaining ligaments were reconstructed employing the described techniques. A total 104 patients with standard fixation were analyzed in the control group. A novel set of criteria was established for the diagnosis of early relapse after facelift surgery based on the validated Merz scale.
Results:
Early relapse rate was significantly lower (0.53% vs 5.76%) in the ligament reconstruction group compared with the control group. Ligament reconstruction was associated with an increased rate of temporary nerve paralysis (8.5%).
Conclusions:
Sub-SMAS reconstruction of retaining ligaments enhances facelift fixation and reduces the rate of early relapse. Increased risk of temporary neuropraxia is a reasonable trade-off.
