Background The hemostatic net, which was initially described as a method to decrease hematoma rates in facelift and necklift procedures, has since increased in practice and applicability. However, despite its demonstrated safety and efficacy, there exists significant skepticism with regard to its necessity; in particular, there is concern that the transcutaneous sutures may restrict dermal perfusion. Objectives The goal of this study was to assess flap perfusion, both before and after application of the hemostatic net, to determine if there was an objective decrease in tissue perfusion in relation to application of the hemostatic net, as measured by laser-assisted angiography (LAA). Methods Eight patients underwent cervicofacial flap reconstruction of cutaneous malignancy defects, after which a hemostatic net was applied. All patients underwent evaluation with LAA both before and after application of the net. The average relative and absolute perfusion of different zones of the flap were calculated. Results The average absolute change in relative perfusion was +6.41%, +0.31%, and +3.28% for zones 1, 2, and 3, respectively, after application of the hemostatic net. There was no statistical difference in relative tissue perfusion after application of the net. There were no instances of delayed healing, infections, ischemia, necrosis, or hematoma. One patient developed a seroma after the net was removed. No patients had scarring or residual track marks from the transcutaneous sutures. Conclusions With LAA, we were able to objectively demonstrate no significant decrease in tissue perfusion after the application of the hemostatic net. Level of Evidence: 4
