Tonsillectomy — 18 Patient Questions
Answered by an ENT Specialist

Recurring tonsil infections usually occur because the tonsils have developed pockets and scarring from repeated inflammation, making them more susceptible to harbouring bacteria. The most common culprit is Group A Streptococcus.

Once this cycle begins, each infection can leave the tonsils more vulnerable to the next — bacterial colonies persist in the tonsillar crypts between episodes, and the local immune response becomes less effective over time.

If you are having four or more infections per year, or if infections are significantly impacting your quality of life or your child's schooling, a specialist review is warranted.

These three are frequently confused because they all cause a sore throat. The differences matter because they require different treatment:

• Common cold — viral, mild sore throat alongside runny nose, cough, and sneezing. No pus on the tonsils. Antibiotics are ineffective and unnecessary.
• Strep throat — bacterial (Group A Streptococcus). Sudden severe throat pain, high fever, white patches or pus on the tonsils, swollen neck glands. Notably, no cough or nasal symptoms. Requires antibiotics.
• Tonsillitis — simply means inflammation of the tonsils. It can be caused by a virus or bacteria. Strep throat is one form of bacterial tonsillitis. The two terms are often used interchangeably in practice.

Most tonsil swelling during an infection is benign and resolves within a week. However, certain patterns of swelling warrant urgent ENT review:

• Swelling involving only one tonsil
• Swelling persisting beyond three weeks without a clear infectious cause
• Swelling associated with a lump in the neck
• Difficulty swallowing, muffled voice, or inability to open the mouth fully
• Swelling in an adult over 40, particularly with a history of smoking or alcohol use

These features require examination to exclude causes including abscess formation, lymphoma, and tonsillar carcinoma.

Yes, though it is uncommon. Tonsillar carcinoma — usually squamous cell carcinoma or lymphoma — can present as a unilateral swollen tonsil, a visible mass, a persistent ulcer, or unexplained neck lymph node swelling.

Risk factors include smoking, heavy alcohol use, and HPV infection. The incidence of HPV-related tonsillar carcinoma has been rising significantly over recent decades.

The most widely used standard is the Paradise criteria:

• Seven or more documented throat infections in one year
• Five or more per year for two consecutive years
• Three or more per year for three consecutive years

Surgery is also considered for tonsils that are causing airway obstruction, obstructive sleep apnoea, a peritonsillar abscess, or where there is a clinical concern about malignancy.

Counting infections alone is not sufficient — the decision requires a clinical examination, a discussion of impact on daily life, and an assessment of whether the criteria are met based on documented episodes rather than memory.

In almost all cases, both tonsils are removed. Even if only one side appears more problematic, removing both prevents future infection in the remaining tonsil and avoids the need for a second procedure.

A unilateral (one-sided) tonsillectomy is performed only in specific circumstances — most commonly when there is a suspicion of asymmetry requiring histological examination to exclude malignancy.

Yes. Tonsillectomy is always performed under general anaesthesia — for both children and adults. This ensures the patient is completely still during the procedure, which is essential for safe surgery in the throat.

The procedure itself takes approximately 20 to 30 minutes. The time in the hospital is longer — typically a few hours — to allow recovery from the anaesthetic before discharge.

In most straightforward cases, yes — patients are discharged the same day once they have recovered from the anaesthetic, are able to swallow fluids, and pain is adequately managed.

An overnight stay may be recommended for:

• Children under three years of age
• Patients with significant obstructive sleep apnoea
• Patients with medical conditions requiring closer monitoring post-anaesthesia

Adults can absolutely have tonsillectomies — and frequently do. There is no upper age limit if the clinical indication is present and anaesthetic fitness is established.

The key difference: recovery is significantly harder for adults. Pain lasts longer (typically 10–14 days versus 5–7 in children), the risk of secondary bleeding is slightly higher, and the time off work is greater. Adults should be prepared for a more demanding recovery than children typically experience.

There is no single ideal age. Tonsillectomy can be performed in children from around three years of age, though surgeons generally prefer to wait unless the indication is clear.

The decision is based on:

• Frequency and severity of infections
• Impact on schooling and quality of life
• Presence of airway obstruction or sleep apnoea
• The child's overall health and fitness for anaesthesia

There is no clinical benefit to delaying surgery if the criteria are met. Waiting does not reduce surgical risk and may allow further structural damage to the tonsils over repeated infections.

Tonsillectomy recovery is genuinely painful — patients should be prepared for this honestly, not reassured otherwise.

The typical pattern:

• Days 1–3: Moderate to severe pain, often managed well with regular analgesia
• Days 4–5: Some improvement
• Days 5–10: Pain often worsens again as the white surgical scabs begin to separate — this is normal and expected, not a sign of infection
• Day 10–14: Gradual improvement toward normal

Pain frequently radiates to the ear — this is referred pain from the same nerve supply and does not indicate an ear problem. Taking analgesia regularly on a schedule — rather than waiting for pain to escalate — is far more effective than treating breakthrough pain.

Staying hydrated is the single most important thing — dehydration is the main reason patients end up readmitted after tonsillectomy, and it makes pain significantly worse.

Food guidance by phase:

• Days 1–3: Cold, smooth foods — ice cream, cold yoghurt, cold milk, cool water, smoothies, ice lollies
• Days 4–7: Soft foods — porridge, mashed potato, soft rice, scrambled eggs, soup
• Week 2: Gradually return to normal diet as tolerated

• Talking: Possible throughout recovery, though uncomfortable. Voice may sound muffled initially.
• Desk work / office: Most adults require 10–14 days off. Voice-intensive work may need two to three weeks.
• Children returning to school: Usually one to two weeks.
• Exercise: Light walking after one week; strenuous exercise, gym, and heavy lifting should wait two full weeks due to the risk of raising blood pressure and triggering secondary bleeding.
• Swimming: Avoid until fully healed — typically three weeks.

• Aspirin and ibuprofen — unless specifically prescribed. These thin the blood and increase bleeding risk. Use paracetamol-based analgesia unless your surgeon advises otherwise.
• Smoking and alcohol — both impair mucosal healing and increase complication risk.
• Passive smoke exposure — keep the patient away from smoking environments.
• Crowded places — infection risk is higher during the healing period.
• Strenuous activity — for two weeks minimum.
• Long-haul flights — avoid for two weeks; cabin pressure and air quality can affect healing.

For patients who meet the clinical criteria, tonsillectomy is highly effective. Evidence consistently shows an 80–90% reduction in throat infections in the year following surgery. Most patients who had four to seven infections per year have none or one.

The benefit is durable — the tonsils are the anatomical source of recurring streptococcal infection, and their removal eliminates that source. Patients may still occasionally get throat infections from pharyngeal tissue, but the pattern of repeated, severe tonsillitis typically resolves.

True regrowth of tonsils after a complete tonsillectomy is very unlikely. A complete tonsillectomy removes the entire tonsil including its capsule, leaving no residual lymphoid tissue to regrow.

Partial regrowth can occur after subtotal (partial) tonsillectomy techniques, which are sometimes used in children primarily for sleep apnoea. If a patient continues to have throat infections after surgery, it is usually due to residual lymphoid tissue in the back of the throat — not true tonsillar regrowth.

Tonsil stones (tonsilloliths) are calcified deposits that form in the crypts of the tonsils. They are composed of compacted bacteria, dead cells, and food debris. They cause:

• Persistent bad breath that does not respond to brushing
• A sensation of something stuck in the throat
• Occasional mild discomfort or a visible white spot on the tonsil

Most cases can be managed without surgery through regular vigorous gargling, water flossing, and good oral hygiene. Tonsillectomy is considered when stones are recurrent, large, symptomatic, and have not responded to conservative management over a reasonable period.

Secondary haemorrhage (bleeding after the first 24 hours) occurs most commonly between days 5 and 10 when the surgical scabs separate. The overall rate varies depending on surgical technique — published data shows approximately 1.7% with cold steel dissection, rising to 4–5% with diathermy and plasma ablation techniques. Your surgeon will have discussed the technique being used, but as a patient you are unlikely to know the exact rate applicable to your procedure.

Guidance:

• Any frank bleeding from the throat after surgery — go to A&E immediately
• If the bleeding is heavy — call emergency services
• Spitting out slightly blood-stained saliva in the first 24 hours is common and not an emergency
• Do not drink hot fluids or take aspirin — both can worsen bleeding

Bleeding that appears to stop can restart — hospital assessment is always required even if bleeding seems to have settled.
