What is a tonsillectomy? Tonsillectomy is an operation to remove the palatine tonsils from the back of the throat. It may be recommended for selected patients with recurrent significant tonsillitis, obstructive sleep-disordered breathing, abscess complications or another specific medical concern.
When may surgery be considered? For recurrent infection, the decision is based on the documented number and severity of episodes, test results, complications and the effect on school, work and quality of life. In children, commonly used criteria include seven significant episodes in one year, five per year for two years, or three per year for three years, although individual factors may modify the decision. Surgery may also be considered when enlarged tonsils contribute to obstructive sleep apnea.
What happens during surgery? The procedure is performed under general anaesthesia through the mouth, so there is no external neck scar. Different surgical techniques may be used. Many patients go home the same day, while some need observation depending on age, health and sleep-related risk.
Recovery Throat pain is expected and may also be felt in the ears. Pain can fluctuate and may become more noticeable several days after surgery. Drinking enough fluid, following the prescribed pain plan and gradually returning to food are important. Recovery commonly takes around 10 to 14 days, but adults may require longer.
Bleeding risk Bleeding is an important potential complication and can occur immediately or during the healing period. Fresh blood from the mouth or repeated swallowing that may indicate bleeding requires urgent medical assessment. The treating surgeon’s emergency instructions should always be followed.
Other risks Risks include anaesthetic complications, infection, dehydration, nausea, dental or lip injury and temporary voice or taste changes. Removing the tonsils does not usually cause a clinically important reduction in immunity.
Expected benefits The operation can reduce future tonsil infections or improve obstruction-related sleep symptoms in appropriately selected patients, but it does not prevent every future sore throat.
