Tonsillectomy is commonly performed clinically by peeling method, squeezing and cutting. The means are conventional peeling, electric knife, laser, plasma. And among these means plasma has the most advantages. The electric knife and laser are high-temperature knives, which cause great damage to the tissue and heavy postoperative reactions. While plasma is at low temperature (40~70℃), which is light on tissue damage. We applied plasma to perform tonsillectomy according to the peeling method from April 2010 to April 2011, and it has good advantages compared with the conventional peeling method intraoperatively and postoperatively. We report the following. 1. Methods General anesthesia was used in all cases. In the control group, the peeling method was performed: the tonsils were peeled from above and downward along the perineum, and the trap was used to remove the tonsils and then the gauze ball was compressed to stop the bleeding, and the bleeding points were sutured to stop the bleeding or electrocoagulated to stop the bleeding. Plasma knife group: low-temperature plasma surgical system (USA, Jesse) Evac70 head, energy set to 6 gears, the knife head along the tonsillar peritoneum from the upper pole to the lower excision of tonsils, foot switch control, cutting and hemostasis at the same time. Postoperatively, routine antibiotics were used to prevent infection for 3 to 5 days. 2. Results We compared the operative time (from cutting the tonsils on one side until the tonsils on the other side were removed and sufficiently hemostatic), intraoperative and postoperative bleeding, postoperative pain, postoperative local tissue edema reaction and pseudomembrane formation, and complications in the two groups. Postoperative bleeding occurred in two cases in both groups. The bleeding occurred within 24 hours by the stripping method, with a bleeding volume of about 30 ml, and the bleeding stopped after suturing of the bleeding point by local anesthesia; the two cases of bleeding in the plasma group occurred on the 4th and 5th postoperative days, with a small amount of bleeding (1-2 ml) on the trauma surface due to improper diet, which was not treated specially and the bleeding stopped spontaneously.
