ABSTRACT
BACKGROUND:
The hemostatic net is a recent technique initially developed to reduce the occurrence of postoperative hematomas following facelift procedures. Its applications have expanded to include skin redraping, deep plane fixation, and other areas beyond the face. However, no experimental study has investigated its effect on skin blood supply.OBJECTIVES:
The aim of this study was to analyze facial skin vascularization after applying a hemostatic net to fresh cadavers.METHODS:
Fourteen hemifaces from fresh adult cadavers were examined. The study model involved a deep plane facelift procedure with the use of a hemostatic net. The first step, involving 4 hemifaces, included dissections and two-/three-dimensional angiographies by digital microangiography and computed tomography scan, respectively. The purpose was to evaluate the influence of the hemostatic net on vascular perfusion. The second step involved a sequential dye perfusion study performed on 10 other hemifaces that underwent facelift procedures with the hemostatic net to determine its impact on skin perfusion.RESULTS:
The anatomic and radiologic techniques enabled visualization of skin, and showed the arterial system reaching the subdermal vascular plexus and branching between the vascular territories, without interference from the net. The sequential dye perfusion study showed staining after injection in each facelift flap, with comparable coloration distributions before and after the application of the net.CONCLUSIONS:
The hemostatic net did not affect the skin blood supply, correlating with no clinical increases in ischemia and necrosis rates in the facelift flap. This study provides additional evidence supporting the safety of the hemostatic net in clinical practice.
