The adenoids, or pharyngeal tonsils, are located at the junction of the parietal and posterior walls of the nasopharynx, between the two pharyngeal crypts. The adenoids are usually removed without making a surgical incision on the skin surface, but mainly with the help of a nasal endoscope that is placed into the posterior wall of the nasopharyngeal apex through the oral cavity or nasal cavity to find the adenoids. 1. through the oral cavity: traditional adenoidectomy is commonly performed under non-direct vision, but it is easy to cause damage to the adjacent tissues and has a high risk of complications and a high rate of postoperative adenoidal residuals. Some patients may require secondary surgery; 2. Transnasal operation: including indirect nasopharyngoscopic adenoids scraping, nasal endoscopic application of power system adenoids cutting and attraction, etc., generally through the nasal endoscopic way of surgery, can clearly observe the shape, size and boundary of the adenoids, facilitate the surgical operation, can be complete removal of adenoids at the same time also avoid cutting to the surrounding tissue. In addition, low-temperature plasma radiofrequency ablation can be used to completely eliminate the adenoids and protect the surrounding tissues while simultaneously stopping the bleeding, which improves the problem of large intraoperative and postoperative bleeding. In addition, pathological hyperplasia can cause nasal congestion, open-mouth breathing, snoring, and adenoid facial deformities in the jaw.
