Why Do Kids Get Their Tonsils Removed?

Tonsils are small, fleshy organs located at the back of the throat. Tonsil removal, a procedure known as tonsillectomy, is a common surgical intervention performed in children. This procedure aims to alleviate various health issues stemming from problematic tonsils.

Understanding Tonsils

The tonsils are lymphoid tissues and part of the body’s immune system. Positioned at the entrance of the respiratory and digestive tracts, they serve as a first line of defense against inhaled or ingested pathogens. These organs contain white blood cells and produce antibodies to help fight off germs. Other lymphoid tissues in the body can take over their function if the tonsils are removed.

Key Conditions Leading to Removal

Two primary medical reasons lead to tonsillectomy in children: recurrent infections and obstructive sleep-disordered breathing. Both conditions can significantly affect a child’s health and daily life, prompting medical intervention when conservative treatments are insufficient.

Recurrent Infections

Frequent or severe tonsil infections are a common reason for tonsil removal. These infections can be caused by viruses or bacteria, often like strep throat. Symptoms include persistent sore throat, difficulty swallowing, fever, tender lymph nodes in the neck, and sometimes a white or yellow coating on the tonsils.

Such recurring episodes can disrupt a child’s schooling and general well-being, leading to missed days and discomfort. Ongoing inflammation and swelling can last longer than two weeks, impacting a child’s ability to eat comfortably and engage in normal activities. When these infections become frequent, the tonsils become a source of ongoing health problems instead of protecting the body.

Obstructive Sleep-Disordered Breathing/Sleep Apnea

Enlarged tonsils can obstruct the airway during sleep, a condition known as obstructive sleep apnea (OSA). This obstruction causes snoring, pauses in breathing, gasping, or choking during sleep, leading to restless sleep and frequent awakenings. Children with OSA may also experience mouth breathing, night sweats, or bedwetting.

The daytime consequences of untreated sleep apnea can be substantial for children. These include daytime fatigue, irritability, hyperactivity, and behavioral problems, sometimes leading to misdiagnosis as attention-deficit/hyperactivity disorder (ADHD). Long-term implications can also extend to growth issues, poor academic performance, and in rare cases, cardiovascular strain.

Deciding on Tonsillectomy

The decision to perform a tonsillectomy involves careful consideration of several factors, including the severity and frequency of symptoms, their impact on a child’s quality of life, and the effectiveness of prior treatments. Medical guidelines help doctors determine when surgery is the appropriate course of action.

For recurrent infections, surgery may be considered if a child has experienced at least seven documented throat infections in the past year; five episodes per year for two consecutive years; or three or more episodes per year for three consecutive years. Each episode should be confirmed by criteria such as a temperature above 101°F (38.3°C), tender cervical lymph nodes, pus on the tonsils, or a positive strep test.

The overall impact on a child’s daily life is a significant consideration. Chronic issues like frequent infections or disturbed sleep can lead to poor school performance, behavioral difficulties, and impaired growth. Doctors also consider whether non-surgical treatments, such as antibiotics for infections or managing allergies, have been attempted and proven insufficient.

For obstructive sleep apnea, a sleep study is often used to confirm the diagnosis and assess the severity of the condition. This overnight study monitors breathing patterns, oxygen levels, and heart rate during sleep. The results help determine if the tonsils are causing significant airway obstruction and if surgery is warranted.
