An Objective Comparison of Holding, Slippage, and Pull-Out Tensions for Eight Suspension Sutures in the Malar Fat Pads of Fresh-Frozen Human Cadavers

The various suture suspension systems currently available have differing efficacy and safety profiles. The results of this cadaver study clarify our understanding of the safety, benefits, and limitations of these systems. The higher ounces of tension for the ePTFE and Woffles sutures were to be expected, because these systems employ double suture strands that grasp a wider area than single-suture systems. Limitations of the study include the small number of samples, possible departures from clinical technique, and the inherent differences of the elastic and suture-holding properties between fresh-frozen cadaveric versus living tissue.
