Adenoid hypertrophy is a common condition in children, primarily caused by excessive growth of the adenoid tissue on the posterior wall of the nasopharynx. This can lead to sleep apnea, snoring, and nocturnal hypoxia in patients, subsequently causing a decline in memory, lack of concentration, fatigue, and other symptoms. In mild cases of adenoid hypertrophy, where there are no significant symptoms of breath-holding or hypoxia, conservative treatment can be applied. This includes the use of steroid nasal sprays and oral administration of nasal decongestant granules, which can alleviate snoring and excessive nasal secretions. However, if a patient exhibits clear symptoms of breath-holding or hypoxia, and adenoid hypertrophy is confirmed through sleep monitoring, surgery is then necessary to treat the condition.
