The adenoid, also known as the pharyngeal tonsil or lymphoid tissue, is located at the top of the nasopharynx and the posterior pharyngeal wall. It looks like an orange segment and is most active in growth from ages 2 to 6 in children, gradually atrophying after age 10. Due to repetitive inflammation, the adenoid can undergo pathological hyperplasia, known as adenoid hypertrophy, which can cause clinical symptoms such as nasal congestion and mouth breathing. The main cause of adenoid hypertrophy is inflammation in the nasopharyngeal region or the adenoid itself. Repeated stimulation leads to pathological hyperplasia. Common causes include recurrent acute and chronic nasopharyngitis, various acute infectious diseases in childhood, which exacerbate nasal congestion symptoms, obstruct nasal drainage, and nasal and sinus secretions further stimulate the adenoid, causing it to continue to grow and creating a vicious cycle.

Does adenoid hypertrophy affect development and height?

Adenoid hypertrophy affects development and height. In this case, due to prolonged enlargement of the adenoids, the patient will experience persistent nasal congestion, along with snoring during sleep. Prolonged hypoxia will lead to developmental delays, short stature, and adenoid facies among other symptoms. Adenoid hypertrophy is mainly caused by the symptoms arising from repeated inflammatory infections, most commonly occurring in children aged three to eight. It can lead to nasal congestion, snoring, hearing loss, tinnitus, and a feeling of blocked ears. In severe cases, it can cause abnormal development of adenoid facies, as well as short stature. It is necessary to visit a hospital for a detailed examination, where an electronic nasopharyngoscope can confirm the diagnosis. In terms of treatment, prolonged adenoid hypertrophy may require adenoidectomy to completely cure the condition.

Does adenoid hypertrophy cause a runny nose?

Adenoid hypertrophy can cause a runny nose, which is a very common symptom of adenoid hypertrophy. Since the adenoids are located at the back of the nasal cavity, specifically in the nasopharynx, the mucus secreted by the nasal cavity normally flows backward, precisely to the back of the nasal cavity, passing over the adenoids. When the adenoids are enlarged, they block the drainage pathway of the mucus, causing most of it to flow out from the front of the nasal cavity. Therefore, adenoid hypertrophy can lead to a runny nose, which is one of its symptoms, and can also cause related symptoms of rhinitis such as nasal congestion. After nasal congestion, it may lead to various other manifestations, including snoring.

Reasons for adenoid hypertrophy in children

There are many causes of adenoid hypertrophy in children, most of which are due to infections. For instance, infections like pharyngitis or sinusitis can trigger adenoid hypertrophy. If a child experiences adenoid hypertrophy, it is recommended to visit the otolaryngology department of the hospital for a checkup. After a detailed examination to determine the specific cause, treatment can be tailored based on the child's individual condition. It is important to avoid greasy, spicy, and irritating foods when dealing with adenoid hypertrophy. It's advised that children consume plenty of fresh vegetables and fruits and engage in more outdoor activities.

Can adenoid hypertrophy be felt by touch?

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.

Can adenoid hypertrophy be seen with the naked eye?

Adenoid hypertrophy is a common disease in otolaryngology, and it is not visible to the naked eye. The diagnosis of excessive growth and hypertrophy of adenoid tissue is mainly made through electronic nasopharyngoscopy and lateral nasopharyngeal radiograph examinations. Typically, if the adenoid tissue occupies more than 2/3 of the posterior nasal aperture, it can be diagnosed as adenoid hypertrophy. Patients mainly show symptoms such as snoring, breath-holding, and hypoxia during sleep at night, as well as daytime sleepiness and reduced memory. Patients with adenoid hypertrophy require surgical ablation of the hypertrophied adenoid tissue to improve their sleep conditions at night and achieve cure.
