Parents frequently observe symptoms such as excessive mouth breathing, loud snoring, and/or nasal obstruction in their children, and typically believe that these issues will resolve themselves over time. As such, most parents do not seek medical advice, although symptoms continue to persist.
It is not uncommon for enlarged adenoids to be the reason for a child’s continuous mouth breathing or snoring when the child sleeps. Enlarged adenoid tissue can cause many issues with a child’s ability to breathe during the day and night.
A child’s ability to develop can be severely affected by the enlargement of adenoids. Therefore, understanding the causes of adenoid enlargement and the benefits of obtaining timely professional medical attention from a Pediatric ENT Specialist can help avoid long-term complications and promote a healthy, happy child.
Adenoid Enlargement in Kids: Causes, Symptoms, and Treatments
Adenoid Enlargement Develops Due to Repeated Infections and Immune Response
Adenoids, a form of lymphoid tissue, can be found behind the nose, and they provide a defence against infections during infancy. Some children may develop hypertrophied adenoids as they have been exposed multiple times to various viral/bacterial agents (viruses/bacteria).
Many children initially have healthy adenoid tissues, but subsequently develop persistent swelling of the adenoids due to daily exposure to the associated factors with repeated episodes of culture-negative purulent upper respiratory tract infections, often accompanied by concurrent allergic rhinitis. The continued exposure to pollution and secondhand tobacco smoke has been shown to exacerbate increases.
There is also a genetic influence on the strength of the immune response in children; therefore, some kids will exhibit an increased incidence of enlarged adenoids from the ages of two through seven years. Most children with enlarged adenoids typically experience a decrease in the size of their adenoids as their immune systems mature.
Enlarged Adenoids Cause Breathing, Sleep, and Ear-Related Symptoms
The enlargement of adenoids can have an impact on both daily living and the quality of sleep due to the obstruction of airways. In children, one of the first indications of adenoid enlargement is nasal obstruction.
Typical symptoms of an enlarged adenoid include:
- Continuous nasal congestion
- Mouth-breathing both daytime and nighttime
- Snoring by children and interrupted sleep patterns
- Voice quality that has a nasal sound
- Multiple ear infections
- Fluid build-up resulting in difficulty hearing
Many children exhibit signs of fatigue during daytime hours, and a lack of adequate sleep will hinder their ability to maintain concentration and learn effectively. Several children may exhibit facial growth changes secondary to chronic mouth breathing.
Adenoid Enlargement Interferes With Normal Breathing and Sleep Patterns
When an individual’s adenoids become enlarged, airflow through the nasal passages may be blocked, causing the child to breathe through their mouth to compensate; this leads to dry oral tissues and greater susceptibility to infection.
At night, when airway obstruction becomes worse, children can experience sleep disruption. Often, children will snore very loudly and consistently throughout the night, while others may experience apnea (pauses while breathing) as a result of sleep-disordered breathing.
In addition to affecting growth hormone production, lack of quality sleep may also result in behaviour-related issues developing for the child. Early treatment is essential in preventing these complications from becoming long-term issues.
Mild Adenoid Enlargement May Reduce Naturally With Age
Only some kids require treatment for enlarged adenoids. Mild cases may resolve over time as the immune system continues to mature and develop. Usually, adenoids shrink after the age of eight years.
In addition to monitoring mild cases that do not have significant symptoms, we will make decisions about the best way to manage these cases based on symptom improvement. We recommend regular follow-ups to identify complications early on.
For children who breathe easily and sleep well, observation is the best method of management. If a child has persistent symptoms, further evaluation by an ENT specialist is warranted.
ENT Specialists Diagnose Adenoid Enlargement Using Clinical Examination
The field of pediatric ENT medicine places priority on obtaining an accurate diagnosis before commencing treatment. When obtaining a pediatric ENT diagnosis, physicians will typically take a thorough history of the child’s symptoms and perform a thorough physical examination of the child.
Methods of diagnosis may include:
- Endoscopic examination of the nasal passage.
- X-rays of the nasal passage.
- An ear exam that includes checking for fluid accumulation within the ear.
- Audiological testing, if warranted.
An endoscopic examination enables visualization of the adenoids directly. An endoscopic examination provides a definitive assessment with minimal patient discomfort. The benefit of early recognition and diagnosis is reduced incidence of repetitive infections and hearing impairment.
Medical and Surgical Treatments Manage Adenoid Enlargement Effectively
The type of medical treatment offered will depend on a child’s age and the severity of symptoms.
Medical treatments for this type of allergy include:
- Nasal steroid sprays
- Allergy management Treatment of related infections
- Monitoring of sleep and breathing patterns
Surgery will be recommended if the child has not responded to medical treatment, with the overall goal of restoring the airway for nasal breathing and improving the quality of sleep.
Regular follow-up visits are essential for managing symptoms and promoting a healthy, developing individual.
Adenoidectomy Becomes Necessary in Persistent or Severe Cases
Adenoidectomy is a surgical procedure to remove enlarged adenoids. When symptoms continue despite medication, doctors will recommend this procedure for children.
Common indications for adenoidectomy include:
- Significant nasal obstruction in children
- Chronic mouth breathing
- Repeated infections of the ear with hearing impairment
- Sleep disorder, apnea and/ or breathing problems
- Alteration of speech and/or facial structure
The procedure remains both safe and effective; typically, children recover rapidly after an adenoidectomy. The improvement in breathing and sleeping should take place within a few weeks.
ENT pediatric specialists provide a thorough assessment before making the recommendation for surgery, and the importance of postoperative follow-up visits is crucial to obtaining optimal long-term outcomes.
