Abstract
The aim of the present study was to evaluate the histological results of the Onemytis® plasma surgery device with Airplasma® technology. We compared the efficacy and the effect on tissues of the new plasma electrocoagulation system with electrosurgery and a scalpel blade. Samples of healthy skin tissue from four dogs that underwent mastectomy were evaluated. Three different incision modes were used, i.e., a cold blade, electrosurgery, and the Onemytis® plasma scalpel were evaluated histologically to assess invasiveness and tissue injuries at different distances from the cutting surface. The histological examinations showed moderate necrosis caused by Onemytis®, compared to the use of the more invasive electrosurgery, which induces thermal damage that extends beyond 1000 µm. Our study shows that the use of the plasma scalpel reduces the extension of the thermal lesion on the skin compared to an electrosurgical scalpel.
