Recurrent Sore Throats to Breathing Problems: When Do Doctors Decide to Remove Tonsils?

A sore throat, fever, and difficulty swallowing are common symptoms of tonsillitis, an inflammation of the tonsils caused by a viral or bacterial infection. While most cases improve with appropriate care, some people experience repeated infections or enlarged tonsils that interfere with breathing, sleep, and eating. In such situations, doctors may recommend a tonsillectomy, a surgical procedure to remove the tonsils.

However, not every episode of tonsillitis requires surgery. The decision depends on how frequently infections occur, their severity, and whether enlarged tonsils cause other health problems.

What Are the Tonsils and Why Are They Removed?

Tonsils are two small masses of tissue at the back of the throat. They form part of the immune system and help the body recognise and respond to germs entering through the mouth and nose.

Tonsillectomy may be recommended when the tonsils repeatedly become infected, remain significantly enlarged, or cause complications. Doctors weigh the potential benefits of surgery against its risks, recovery time, and the possibility that symptoms may improve without an operation.

When Do Doctors Recommend Tonsil Surgery?

Frequent episodes of tonsillitis

Repeated tonsil infections are among the main reasons for considering surgery. Doctors may discuss tonsillectomy when a patient has:

• Seven or more documented episodes of tonsillitis in one year.
• Five or more episodes each year for two consecutive years.
• Three or more episodes each year for three consecutive years.

There are commonly used clinical thresholds, rather than automatic rules for surgery. The episodes should be adequately documented, clinically significant, and disruptive to everyday life. Doctors also consider missed school or work, the severity of symptoms, and whether appropriate treatment has helped.

Patients who do not meet these thresholds may still need specialist assessment if their infections are unusually severe or cause complications.

Enlarged tonsils causing breathing or sleep problems

Tonsils can become so enlarged that they narrow the airway, particularly during sleep. This may cause loud snoring, restless sleep, repeated pauses in breathing or obstructive sleep apnoea.

In children, disrupted sleep may also contribute to daytime sleepiness, behavioural difficulties and problems with concentration. Doctors may recommend surgery when enlarged tonsils are responsible for significant airway obstruction or sleep-disordered breathing.

The decision depends on the symptoms, examination findings and, in some cases, a sleep study.

A peritonsillar abscess

According to the American Journal of Otolaryngology, a peritonsillar abscess is a collection of pus that develops near a tonsil, usually following an infection. It can cause severe throat pain, difficulty opening the mouth, a muffled voice, and difficulty swallowing.

Treatment often involves draining the abscess and giving appropriate medication. Tonsillectomy may be considered if the abscess recurs, the patient has a history of repeated tonsillitis, or other clinical factors make surgery appropriate.

Difficulty swallowing or other complications

Very enlarged tonsils can sometimes interfere with swallowing, eating, or drinking. In children, this may affect feeding and growth. Doctors may consider surgery if the obstruction is significant and clearly linked to the tonsils.

Less commonly, surgery may be considered in selected cases of persistent tonsil-related problems that have not responded to other treatments. The underlying cause must be assessed before deciding on an operation.

When Is Tonsil Surgery Not Necessary?

Most viral sore throats and many episodes of tonsillitis resolve without surgery. Antibiotics are useful for certain bacterial infections but do not treat viral infections.

Doctors may recommend observation, symptom relief, and appropriate treatment instead of surgery when infections are infrequent, symptoms are manageable, and there are no significant breathing problems or complications.

Tonsil removal also does not prevent every future sore throat because other tissues in the throat can still become infected.

What Should Patients Expect After Surgery?

Tonsillectomy is usually performed under general anaesthesia. Recovery commonly takes around 10 to 14 days, although it can vary. Throat pain, ear pain, and difficulty swallowing are common during recovery.

Bleeding is an important complication to watch for. Any fresh bleeding from the mouth after tonsil surgery requires urgent medical assessment. Difficulty breathing or being unable to maintain adequate fluid intake also warrants prompt medical attention.

When Should You Consult an ENT Specialist?

Consult an ear, nose and throat (ENT) specialist if you or your child experiences repeated severe tonsillitis, persistent loud snoring with pauses in breathing, difficulty swallowing, or recurrent tonsil-related complications.

Seek urgent care for breathing difficulty, inability to swallow saliva or signs of a serious throat infection. 

Ultimately, doctors recommend tonsil removal when the expected benefits outweigh the risks.

The decision should be individualised, based on the patient's symptoms, medical history and examination rather than the size of the tonsils or the number of sore throats alone.
