Posterior pharyngeal wall follicles may or may not subside on their own. Posterior pharyngeal wall follicles caused by acute pharyngitis can be treated with medication, while those caused by chronic pharyngitis can be eliminated by plasma surgery. Posterior pharyngeal wall follicles usually proliferate during acute pharyngitis, and can be treated with medication under the guidance of a doctor to eliminate the inflammation, such as cefixime dispersible tablets, and follicular hyperplasia may subside after the acute inflammation subsides. If the pharynx has repeated inflammatory stimulation or already suffers from chronic hypertrophic pharyngitis, the follicular hyperplasia may not be eliminated on its own, and if there is obvious foreign body sensation, the follicle can be eliminated by plasma surgery. It is recommended to go to the hospital after examination to clarify the diagnosis, and follow the doctor’s instructions to standardize the use of drugs and treatment.
