Adenoiditis is an inflammation of the adenoids, small lymphatic tissues located at the back of the nasal cavity. These tissues play an important role in defending the body against infections in children, but they can sometimes become infected themselves. Adenoiditis is most common in children aged 2 to 7 years, though adults can occasionally be affected as well.
Understanding the causes, symptoms, and available treatments for adenoiditis is essential for parents and caregivers, since untreated cases can lead to chronic breathing problems, ear infections, or sleep disturbances.
What Are the Adenoids?
The adenoids are part of the body’s immune system. Along with the tonsils, they trap bacteria and viruses that enter through the mouth and nose. While adenoids are useful in early childhood, they gradually shrink as a child grows and usually disappear by adolescence.
When adenoids become infected, they swell, leading to nasal obstruction, snoring, and recurring ear or sinus problems. This condition is known as adenoiditis.
Causes of Adenoiditis
Adenoiditis can be caused by different types of infections or irritants:
-
Bacterial infections – The most common cause, often linked to Streptococcus, Haemophilus influenzae, or Staphylococcus aureus.
-
Viral infections – Such as adenovirus, influenza virus, or respiratory syncytial virus (RSV).
-
Allergic reactions – Chronic allergies can cause adenoid inflammation.
-
Environmental factors – Exposure to smoke, pollution, or irritants may worsen symptoms.
Children with frequent respiratory infections are at higher risk of developing adenoiditis.
Symptoms of Adenoiditis
The symptoms vary depending on the severity of inflammation, but may include:
-
Nasal blockage – Difficulty breathing through the nose.
-
Mouth breathing – Children may breathe primarily through their mouths, especially at night.
-
Snoring or sleep apnea – Enlarged adenoids can cause sleep disturbances.
-
Recurrent ear infections – Blocked Eustachian tubes can lead to middle ear infections and hearing issues.
-
Runny nose and postnasal drip – Persistent nasal discharge.
-
Sore throat and difficulty swallowing – Due to swelling in the back of the nasal cavity.
-
Swollen lymph nodes – particularly in the neck area.
If symptoms persist for more than a week or worsen over time, medical evaluation is recommended.
Acute vs. Chronic Adenoiditis
-
Acute Adenoiditis – Short-term infection, often caused by bacteria or viruses. Symptoms appear suddenly and may resolve with treatment.
-
Chronic Adenoiditis – Long-term inflammation, where adenoids remain enlarged. This often causes recurring ear infections, constant nasal congestion, and sleep disturbances.
Diagnosis of Adenoiditis
A physician may use several methods to diagnose adenoiditis:
-
Medical history and symptom review – Identifying patterns of ear infections, snoring, or nasal obstruction.
-
Physical examination – Checking the throat, nose, and ears.
-
Nasopharyngoscopy – Using a small flexible camera to visualize the adenoids.
-
X-rays or imaging – To evaluate adenoid size and airway obstruction.
Treatment Options for Adenoiditis
1. Medications
-
Antibiotics – For bacterial infections.
-
Nasal corticosteroids – To reduce inflammation and swelling.
-
Pain relievers and fever reducers – Such as acetaminophen or ibuprofen.
2. Home Remedies and Supportive Care
-
Ensuring the child gets plenty of rest.
-
Drinking warm fluids and staying hydrated.
-
Using saline nasal sprays to ease congestion.
-
Running a humidifier to keep air moist.
3. Surgical Treatment (Adenoidectomy)
If adenoiditis becomes chronic or causes frequent ear infections, a doctor may recommend adenoidectomy — surgical removal of the adenoids. This procedure is common, safe, and often performed alongside tonsil removal (tonsillectomy).
Complications of Untreated Adenoiditis
If left untreated, chronic adenoiditis can lead to:
-
Persistent ear infections and hearing problems.
-
Obstructive sleep apnea, which disrupts rest and affects child development.
-
Facial growth abnormalities, sometimes called “adenoid face” (long face, open mouth posture).
-
Recurrent sinus infections.
Prevention Tips
While adenoiditis cannot always be prevented, some measures can reduce the risk:
-
Encouraging good hand hygiene.
-
Avoiding exposure to cigarette smoke or polluted air.
-
Ensuring vaccinations are up to date.
-
Strengthening immunity with a balanced diet, exercise, and adequate sleep.
Adenoiditis in Adults
Although rare, adenoiditis can occur in adults, usually due to chronic infections or allergies. Adult cases often require more thorough investigation since persistent adenoid enlargement could indicate underlying conditions, including, rarely, tumors.
Conclusion
Adenoiditis is a common condition in children that can affect breathing, sleep, and ear health. While mild cases may resolve with antibiotics or supportive care, chronic or severe cases may require surgical removal of the adenoids. Early diagnosis and proper management are essential to prevent complications and ensure healthy development.
Parents should watch for warning signs such as constant snoring, mouth breathing, or recurring ear infections, and consult a healthcare provider for timely treatment.
