Cryogenic plasma radiofrequency technology is a minimally invasive therapy, especially suitable for the special group of elderly and children, and its remarkable and stable efficacy is well received by the majority of patients. Treatment principle: The treatment principle of low-temperature plasma minimally invasive technology is to use the energy of low-temperature plasma radiofrequency to ablate the adenoid lesion tissue at a low temperature of about 40 degrees to restore the normal ventilation of the pharyngeal cavity. And the technology borrows endoscopic treatment, the lesion tissue is magnified several times, the surgical field of view is clearer, the operation is simpler and more precise, ensuring the safety of the operation and reducing the risk.
