This paper summarized the clinical experience on staged differentiation and treatment of adenoidal hypertrophy （AH） in children by regulating

qi

and eliminating adenoids. It is considered that the disease location of AH lies in the nasopharynx， and the pathogenesis is rooted in the disharmony of lung

qi

， while phlegm-heat stasis serves as the manifestation. It is put forward that the general principle of treatment is re-gulating

qi

and eliminating adenoids. In clinical practice， AH in children can be divided into attack stage， progressive stage， and remission stage. The pathogenesis of attack period is wind heat from external contraction and phlegm heat accumulating in the lungs， for which the treatment should be dispersing pathogens and diffusing the lungs， clearing heat and reducing phlegm， and self-made

Xuanfei Xiaoxian Decoction

（宣肺消腺汤） is recommended. The pathogenesis of progressive stage is lung-heat coagulating in throat and phlegm and stasis intermingling， for which the method of clearing heat and draining the lungs， purging phlegm and removing stasis is recommended， with the use of self-made

Xiefei Xiaoxian Decoction

（泻肺消腺汤）. In the remission stage， the core pathogenesis is deficiency of lung and spleen

qi

and phlegm and dampness condensatin； the treatment principle is to strengthen lungs and consolidate defensive

qi

， dry dampness and dissolve phlegm， for which self-made

Bufei Xiaoxian Decoction

（补肺消腺汤） is suggested. Simultaneously， it is recommended to treat comorbidities and modify the formulas according to the symptoms.
