Adenoid hypertrophy can be divided into physiological and pathological hypertrophy. Physiological hypertrophy is a normal part of everyone's development. It begins at the age of three, peaks at about seven, and gradually shrinks around the age of ten. Pathological hypertrophy, on the other hand, often occurs on the basis of physiological hypertrophy, followed by inflammatory stimuli. Factors such as viral infections, colds, and allergic reactions are the main causes of pathological adenoid hypertrophy. This type of hypertrophy can lead to poor respiratory function, symptoms such as snoring during sleep, nasal congestion, and a runny nose. If the enlarged adenoids block the Eustachian tube, it can also lead to secretory otitis media.

Can adenoid hypertrophy be seen with the naked eye?

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.

Treatment methods for adenoid hypertrophy

Adenoid hypertrophy refers to the hyperplasia and enlargement of the adenoid tissue in the nasopharynx, blocking the local upper airway passages, leading to conditions such as rhinitis, sinusitis, otitis media, and snoring during sleep. Clinically, there are two treatment methods: conservative medication and surgery. Currently, there are no specific drugs aimed at adenoid hypertrophy. Typically, treatments involve the use of nasal corticosteroids such as mometasone furoate nasal spray and anti-allergic medications like montelukast. However, the effectiveness of the treatment may vary from person to person or be unpredictable. Generally, medication is first tried for one to three months, or depending on the severity of the adenoid hypertrophy, treatment can last about two weeks to four weeks. If the medication is not effective, or shows no results, surgical intervention to remove the enlarged adenoids and facilitate airway clearance is necessary. (Please use medication under the guidance of a clinical doctor and do not self-medicate.)

Does adenoid hypertrophy require nasal irrigation?

Enlarged adenoids require nasal cleansing, which can be done using saline solution for nasal irrigation. During irrigation, the inflammatory secretions on the surfaces of the nasal cavity and the pharyngeal adenoids can be washed off, thereby alleviating the symptoms of enlarged adenoids. This can relieve the patient's nasal congestion and snoring during sleep. This is a conservative treatment method for enlarged adenoids. Additionally, during the acute phase of enlarged adenoids, symptomatic anti-inflammatory treatment is also necessary, using antibiotics such as penicillins or cephalosporins, which are effective. Administration of budesonide via nebulization can also be combined to reduce congestion and edema of the mucous membrane on the surface of the adenoids, relieving symptoms. If the adenoids remain enlarged for an extended period, and conservative treatments are ineffective, and if the patient has severe snoring symptoms, then adenoidectomy might be necessary to completely cure the condition. (Medications should be used under the guidance of a doctor.)

What should I pay attention to in the diet for adenoid hypertrophy?

Adenoid hypertrophy is a common condition in children, primarily due to excessive growth of adenoid tissue on the posterior wall of the nasopharynx. This condition leads to symptoms such as nasal congestion, snoring during sleep, runny nose, and sinusitis. The main treatment for adenoid hypertrophy is surgical removal. Regarding diet, it is first recommended to reduce the intake of cold beverages and spicy, irritating foods to avoid exacerbating local inflammatory responses. Secondly, it is advised to limit foods containing hormones, as they may stimulate the proliferation and congestion of lymphatic tissue, worsening the degree of adenoid hypertrophy.

Is nasal discharge a sign of improvement in adenoid hypertrophy?

Enlargement of the adenoids accompanied by a runny nose is not a sign of improvement but a symptom of worsening. Enlargement of the adenoids is primarily due to symptoms caused by acute viral or bacterial infections following a decrease in the body’s immunity and resistance. This can lead to diffuse congestion and edema of the glands, causing the patient to experience persistent nasal congestion and discharge of yellow nasal mucus. In severe cases, it can cause nocturnal suffocation. Initially, a detailed examination at the hospital is necessary. Diagnosis can be confirmed with an electronic nasopharyngoscope and a nasopharyngeal CT. During the examination, granular masses can be found on the posterior wall of the nasopharynx; these are soft in texture and not painful. In terms of treatment, during the acute phase of adenoid hypertrophy, symptomatic anti-inflammatory treatment is required, including the use of antibiotics and concurrent nebulizer inhalation to reduce congestion and edema of the adenoids. If the enlargement persists and conservative treatment is ineffective, adenoidectomy may be necessary to achieve a complete cure.
