Footnotes Source of Support: But electrosurgery also has its own limitations in that its repeated and prolonged use induces heat accumulation and undesired tissue destruction. We found that the scalpel technique was relatively simple and versatile and that it required minimum time and effort. A 5-year clinical and transmission electron microscopic study in humans.
One day postoperatively, it revealed no pain or discomfort [ Figure 9 ]. Although healing of laser wounds is slower than healing of scalpel wounds, a sterile inflammatory reaction occurs after laser use.
