Adenoid hypertrophy, if not treated, can have serious consequences. It primarily leads to persistent bilateral nasal congestion that progressively worsens. This is often accompanied by snoring during sleep. Additional symptoms include persistent tinnitus, decreased hearing, and a feeling of stuffiness in the ears. Adenoid hypertrophy can also cause a high-arched hard palate, irregular teeth, and facial deformities. Therefore, once adenoid hypertrophy occurs, active treatment is necessary. Generally, adenoid hypertrophy is caused by inflammation, leading to congestion, edema, and proliferation of the adenoids, which is most common in children aged three to eight. In treating acute adenoid hypertrophy, symptomatic anti-inflammatory treatment is needed, including the use of antibiotics and corticosteroids for local nebulization inhalation. If conservative treatment is ineffective, adenoidectomy using plasma may be necessary. This treatment can completely cure the condition.
