Patient: mainly nasal congestion; chest tightness; more than 10 years have done chemotherapy; nose injections; no use can do plasma surgery; now the plug number uncomfortable; Patient: nasal septum deviation area; inferior turbinate hypertrophy; mucous membrane red ‘nasal congestion; chest tightness; more than 10 years; this year did do inferior turbinate closure surgery ‘and fog chat; do plasma surgery can Is it; now stuffy so uncomfortable; Xiamen Hospital of Otolaryngology Yu Bin: low-temperature plasma technology is the use of bipolar radio frequency technology to generate energy to accelerate the ions in the electric field, relying on ion energy to open the molecular bond on the tissue cutting, hemostasis, ablation, the tissue temperature of 40 ~ 70oC, compared to the laser and microwave of more than 100 degrees high temperature, plasma thermal damage to the surrounding tissue is reduced to a minimum The ablation of the inferior turbinate can protect the function of the nasal mucosa well. Plasma technology was first invented by American scientists and was approved for clinical use by the U.S. Food and Drug Administration in 2000. At present, plasma knife has been widely used in ENT surgery in the United States, with an average of one plasma surgery in every six cases. In China, due to the economic conditions, plasma knives have only been used in individual hospitals since 2003. Since January 2006, our department has performed more than 110 cases of various types of minimally invasive plasma surgery, mainly for the treatment of chronic rhinitis, chronic tonsillitis, pediatric tonsillar and adenoid hypertrophy, and snoring and sleep apnea syndrome in children and adults. Among them, plasma surgery of the pharynx is the first in Fujian Province, and the number of surgical cases is the first in the province.
