Tonsil surgery (Tonsillectomy)

What is tonsillectomy?

Tonsillectomy is an operation to remove the tonsils—two oval lumps of lymphoid tissue at the back of the throat. The tonsils help trap bacteria and viruses, but when they are repeatedly infected or enlarged they can cause more harm than good: recurrent tonsillitis, obstructive sleep apnoea, trouble swallowing, or a constant sore throat. When these problems affect health or day-to-day life, removal is often recommended. The same applies when tonsil stones (hard debris in the tonsil crypts) cause bad breath and discomfort. Recurrent infections left untreated can lead to abscesses, middle ear infections, or in rare cases rheumatic fever, so timely assessment is important.

When is tonsillectomy recommended?

An ENT specialist will suggest surgery when the history and examination support it. Typical reasons include:

• Recurrent tonsillitis: for example more than seven episodes in a year, or five in two consecutive years.
• Obstructive sleep apnoea: enlarged tonsils cause difficulty breathing, snoring, or broken sleep.
• Difficulty swallowing or feeding because the tonsils are too large.
• A long-standing sore throat that does not improve with medication.
• Tonsil stones that cause ongoing halitosis or discomfort.

Surgical techniques

Several techniques are used, each with trade-offs in bleeding, pain, and healing: cold dissection (scalpel removal—effective but can mean more postoperative bleeding); electrocautery (heat to cut and seal vessels—less bleeding but often more painful recovery); harmonic scalpel (ultrasonic energy—precise cut, less bleeding and faster healing in many cases); and coblation (radiofrequency to dissolve rather than cut the tonsils—often less painful and quicker healing). All carry a small risk of bleeding, infection, temporary voice change, and reaction to anaesthesia. Choosing an experienced ENT surgeon and a well-equipped facility helps keep complications low.

Tests before surgery

To confirm the need for surgery and rule out other causes, the doctor may arrange a throat swab to identify bacteria, blood tests to check for other infections or immune issues, and sometimes a sleep study (polysomnography) to see if enlarged tonsils are driving sleep apnoea. After that, treatment options—including surgery—are explained.

Alternatives to surgery

Surgery is not always the first step. Antibiotics can treat bacterial tonsillitis; pain relievers (e.g. ibuprofen, paracetamol) ease sore throats; and corticosteroids may be used for severe swelling and pain. At home, saltwater gargles, plenty of fluids, and honey or lemon can soothe the throat. Tonsil cryptolysis is a laser procedure that shrinks the tonsils without full removal and may suit some people who want to avoid a full tonsillectomy. If infections keep coming back or symptoms persist, surgery is often the most effective long-term option.

What to expect after surgery

You can expect throat pain (especially on swallowing), sometimes felt in the ears or jaw. Painkillers are prescribed and should be taken as directed. Drink plenty of fluids to avoid dehydration and stick to soft foods (porridge, yoghurt, mashed potato, soups) at first; then gradually return to solid food. Avoid spicy, crunchy, or acidic foods that could irritate the raw area. Rest and avoid heavy lifting or strenuous activity until you are fully recovered. Recovery is often around 10–14 days, though some people need up to three weeks; children usually bounce back faster than adults. Contact your doctor if you have heavy bleeding from the throat, high fever or signs of infection, or severe dehydration (e.g. not passing urine, dizziness, unusual weakness). Most people heal well and see lasting benefits: fewer throat infections, better sleep, and less daily discomfort.
