Chronic pharyngitis may have a causal relationship with tonsil cyst formation. Tonsil cysts are formed when the tonsillar crypts are adherent due to inflammatory scarring and the contents cannot be discharged, which is the pathogenesis of tonsil cysts due to chronic cryptogenic tonsillitis. Chronic tonsillitis produces secretions and inflammatory factors will stimulate the pharyngeal mucosa, congestion, capillary dilatation, plasma exudation, so that the submucosal connective tissue and lymphatic tissue hyperplasia, recurrent episodes, and then produce chronic pharyngitis. When chronic pharyngitis has repeated acute attacks and is stimulated by pathogenic factors, it will have an adverse effect on the tonsils at the same time, leading to concomitant or secondary chronic tonsillitis, thus there is the possibility of causing tonsil cysts. If there is discomfort in the pharynx, you should go to the hospital in time for a systematic examination, diagnosis and treatment under the guidance of a doctor.
