Quick answer. A tonsillectomy is an operation to remove the tonsils, usually for repeated bouts of tonsillitis, obstructed breathing in sleep, or an abscess. It is a common ENT procedure with a generally smooth recovery, though bleeding is the main risk to watch for.
A tonsillectomy is the surgical removal of the tonsils, the two soft pads of tissue at the back of the throat. It is one of the more common operations performed by ENT surgeons, in both children and adults, and is usually recommended only when the tonsils are causing repeated or significant problems rather than for a single sore throat.
This guide explains what a tonsillectomy is, the main reasons it is done, how the operation and recovery work, the risks (with bleeding being the most important), and the typical market cost range in Singapore, including where MediSave may apply, so you can discuss it confidently with an ENT specialist.
At a glance
| Indication | What it means | Why surgery may help |
|---|---|---|
| Recurrent tonsillitis | Frequent throat infections each year | Reduces repeated infections and time off |
| Sleep apnoea or snoring | Enlarged tonsils block the airway in sleep | Improves breathing and sleep quality |
| Peritonsillar abscess | A collection of pus beside the tonsil (quinsy) | Prevents recurrence after drainage |
| Difficulty swallowing | Very enlarged tonsils | Relieves obstruction |
| Suspicious tonsil | An unusual or one-sided enlarged tonsil | Allows tissue to be examined |
What is a tonsillectomy?
A tonsillectomy is an operation to remove the tonsils, the pair of oval tissue masses at the back of the throat that form part of the body’s immune defences. Because the rest of the immune system continues to protect against infection, the tonsils can be removed when they cause more harm than good without leaving a person unprotected.
It is performed under general anaesthetic, almost always through the mouth, so there are no external cuts or visible scars. Sometimes the adenoids (tissue behind the nose) are removed at the same time, an operation called adenotonsillectomy, particularly in children with breathing or sleep problems. A tonsillectomy is a well-established procedure and is usually planned in advance once an ENT specialist has confirmed it is the right step.
Who needs it (indications)
A tonsillectomy is generally recommended only when the tonsils cause significant or repeated problems. Common reasons include:
- Recurrent tonsillitis: frequent, well-documented throat infections that disrupt school, work or daily life
- Obstructive sleep apnoea or heavy snoring, where enlarged tonsils block the airway during sleep (a frequent reason in children)
- Peritonsillar abscess (quinsy), a pus collection beside the tonsil, especially if it recurs
- Tonsils so enlarged they make swallowing or breathing difficult
- An unusual, persistently one-sided enlarged tonsil that needs to be examined to exclude other causes
The decision weighs how often and how severely the tonsils cause trouble against the risks of surgery, and is made together with an ENT specialist.
The procedure and recovery
A tonsillectomy is done under general anaesthetic, so you or your child are asleep throughout. The surgeon removes the tonsils through the open mouth using one of several techniques, and the operation itself usually takes well under an hour. Many tonsillectomies are done as day surgery or with a short hospital stay, depending on age and health.
Recovery takes around one to two weeks. A sore throat is expected and is often worst in the first week; ear pain is common and is referred pain from the throat, not an ear infection. Pain relief, plenty of fluids, and eating soft foods help, and staying well hydrated is important. Rest at home is advised, with time off school or work, and avoiding strenuous activity and crowded places while healing. The white coating that forms where the tonsils were is a normal part of healing.
Risks
Tonsillectomy is generally safe, but as with any operation there are risks your surgeon will explain. The most important is bleeding:
- Bleeding, which can happen during surgery or, more concerning, up to about two weeks afterwards as the wound heals. Any fresh bleeding from the mouth after a tonsillectomy needs urgent medical attention.
- Pain, particularly in the throat and ears, during recovery
- Risks of the general anaesthetic
- Infection
- Dehydration if pain makes eating and drinking difficult
- Temporary changes in taste or voice
Knowing the warning signs of bleeding before going home is an important part of a safe recovery.
Typical cost in Singapore
The cost of a tonsillectomy varies with whether it is done in a public or private hospital, the ward class, the surgeon’s and anaesthetist’s fees, and whether the adenoids are removed at the same time. As a broad market guide, a tonsillectomy in Singapore commonly ranges from around a low four-figure sum in subsidised public settings to several thousand dollars or more in private hospitals.
These are general market ranges only, not a quotation. Ask the hospital or clinic for a written, itemised estimate for your specific case. As a recognised day or inpatient surgical procedure, a tonsillectomy is typically claimable under MediSave within the applicable surgical limits, and MediShield Life or an Integrated Shield Plan may cover part of larger bills; government subsidies apply in the public sector for eligible patients. Confirm coverage with the hospital business office and your insurer beforehand.
When to see a doctor & which specialist
During recovery from a tonsillectomy, call 995 or go to the nearest A&E immediately if there is any fresh bleeding from the mouth or throat, as post-tonsillectomy bleeding can be serious. Also seek urgent care for a high fever that will not settle, signs of dehydration, or difficulty breathing.
You should see an ENT specialist if you or your child have repeated bouts of tonsillitis, ongoing heavy snoring with pauses in breathing during sleep, recurrent throat abscesses, or one tonsil that is persistently larger than the other. The specialist can confirm whether a tonsillectomy is appropriate and discuss the options. Find one through our directory of ENT specialists in Singapore.
