The principle of action of low-temperature plasma ablation treatment system is to form a thin layer of plasma between the electrode and the tissue, the ions in the layer are accelerated by the electric field, and the energy is transferred to the tissue, which opens the molecular bond between the cells at low temperature (40°CD70°C), causing the cells in the target tissue to decompose into carbohydrates and oxides causing coagulative necrosis of the tissue, called low-temperature radiofrequency (not thermal effect). Necrotic cells are shed or scar contraction is produced to achieve volume reduction of the target tissue. Clinical applications of plasma technology in otorhinolaryngology: 1. plasma tonsillectomy; 2. plasma adenoidectomy; 3. plasma-assisted uvulopalatopharyngoplasty (CAUP); 4. plasma ablation of hypertrophic turbinates; 5. plasma ablation of tongue root resection. Compared with traditional surgery, the advantages of plasma technology for removal of tonsils, adenoids, ablation of hypertrophic inferior turbinates and plasma-assisted uvulopalatopharyngoplasty are as follows: 1. less intraoperative and postoperative bleeding; 2. less postoperative edema; 3. less postoperative pain; 4. ablation of excess fatty tissue in the palatal sail gap without complete dissection; 5. thinning of hypertrophic lateral pharyngeal cords; 6. submucosal ablation of hypertrophic turbinates, effectively Protect the nasal mucosa and relieve the symptoms of nasal congestion.
