Adenoid hypertrophy is not visible to the naked eye because the adenoids are located on the posterior wall of the nasopharynx. It can only be detected through an electronic nasopharyngoscope or a CT scan of the nasopharynx to determine if there is adenoid hypertrophy. Adenoid hypertrophy is most likely to occur during childhood, typically due to long-term inflammatory infections. It often follows acute rhinitis or acute sinusitis. After adenoid hypertrophy, it can lead to bilateral nasal congestion that progressively worsens, along with snoring during sleep, tinnitus, a feeling of ear congestion, and a decrease in hearing. In severe cases, it can lead to a characteristic facial appearance known as "adenoid facies." It is necessary to have a detailed examination at a hospital for adenoid hypertrophy. An electronic nasopharyngoscope and adenoid CT can confirm the diagnosis. For treatment, during the acute phase of adenoid hypertrophy, symptomatic anti-inflammatory treatment is necessary, along with the use of nebulized inhalation to reduce congestion and swelling of the adenoids. If conservative treatment is ineffective and the adenoid hypertrophy continues to worsen, adenoidectomy may be required to completely cure the condition.
