Low-temperature plasma ablation is a minimally invasive treatment for enlarged adenoids and is commonly used in clinical practice. The main mechanism of low-temperature plasma ablation is to use the energy generated by low-temperature plasma radiofrequency to ablate the adenoid lesions at a plasma temperature of forty to seventy degrees, restoring the normal physiological function. This technique usually requires the use of endoscopic treatment, which magnifies the diseased tissues several times in the local area, making the surgical field clearer, the surrounding tissues clearer, the operation simpler and more precise, and the excision process is almost bloodless, which has the advantage of being truly minimally invasive. Low-temperature plasma ablation is able to remove the lesions while avoiding additional damage to the tissues to form adverse reactions, which can greatly reduce the patient’s pain and shorten the recovery period.
