Cryoablation is the use of plasma cryoablation system to ablate the hyperplastic tissues of rhinitis for the purpose of treating some diseases such as allergic rhinitis, chronic rhinitis and pharyngitis. Cryoablation is the use of nasal endoscopy and the application of plasma cryoablation system to ablate the hyperplastic tissues of rhinitis. This maintains the safety of the local mucosal tissue structure, reduces postoperative edema and painful symptoms, and provides relief for some diseases such as allergic rhinitis, chronic rhinitis, and pharyngitis. The principle is to use low-temperature plasma radiofrequency energy to cut at a lower temperature to achieve the purpose of cutting and stopping bleeding, to reduce the additional damage to the tissue from high temperature, to reduce the pain of patients from the same time, and to shorten the recovery period.
