Adenoid hypertrophy is palpable, as the adenoids are a cluster of lymphoid tissue located at the top of the nasopharynx. If there is localized hypertrophy, it can be directly felt through the mouth. Adenoid hypertrophy most commonly occurs in children, especially those between the ages of three and six, and often follows acute colds, rhinitis, and adenoid hypertrophy, eventually leading to persistent bilateral nasal obstruction. Additionally, it may be accompanied by symptoms such as snoring during sleep, decreased hearing, tinnitus, and a feeling of ear fullness. In severe cases, it may lead to a facial appearance characteristic of adenoid hypertrophy. It is necessary to first visit a hospital for a thorough examination, which can include an electronic nasopharyngoscopy, nasopharyngeal CT, and nasopharyngeal palpation to confirm the diagnosis. In terms of treatment, acute adenoid hypertrophy requires symptomatic anti-inflammatory treatment, along with nebulized inhalation. If conservative treatment is ineffective, adenoidectomy may be necessary for cure.
