Adenotonsillectomy is a procedure that involves the complete removal of the tonsils and adenoids.


The primary indications for Adenotonsillectomy are;

  • Recurrent tonsillitis / sore throats.
  • Obstructive Sleep apnoea.
  • Tonsillar Abscess.


Adenotonsillectomy carries the same general risks as all operations including:

  • Pain.
  • Bleeding.
  • Infection.
  • Scarring.
  • Failure to resolve symptoms.

The main significant risk of Adenotonsillectomy is delayed bleeding, which may occur up to 2 weeks after surgery. This complication occurs in approximately 1-2 per 100 cases when surgery is performed by Dr Morrissey.

Treatment Alternatives

There may be treatment alternatives suitable to you or your child that you can discuss with Dr Morrissey. Recurrent infections may respond to antibiotics in some cases while nasal sprays may assist in obstructive sleep apnoea in limited cases.

Preoperative Instructions

Adenotonsillectomy is performed under a general anaesthetic. You will need to fast prior to surgery and should follow the provided instructions. If you have any queries or concerns please contact your Anaesthetist, admitting hospital or Dr Morrissey.


Under a general anaesthetic the adenoids are removed from behind the nose with a special instrument. Pressure or cautery is applied to control bleeding.

The tonsils are removed using sharp instruments and any bleeding addressed using stitches and / or cautery.

Postoperative Instructions

Return to normal activities

It takes 7-10 days for most children to fully recover. You will need to keep your child away from day-care, kindergarten and school during this period.

General activities can be resumed when your child feels up to it. Please avoid active sports, rough play and heavy lifting for 2 weeks.

Family HQ

Keeping track of medications, temperature and other aspects of care can be difficult following surgery. Please consider using Family HQ and the associated App to make the process a little easier. (

Pain Relief

Children will experience some throat pain and discomfort for up to 10 days following surgery.  Ear pain, jaw pain and neck pain may also occur. This can be improved with pain relief but may not entirely disappear. During this time, it is recommended your child take some regular pain relief.


  • Panadol: Please take every 4 to 6 hours (with a maximum of 4 doses in a 24hr period), continue this regularly for 7-10 days.  If your child refuses oral pain relief medication, Panadol can be given as a suppository. Take as directed by the manufacturer.
  • Anti-Inflammatories (Ibuprofen / Mobic / Celebrex): Please take regularly following surgery as prescribed by your doctor.
  • Oxycodone Syrup: This may be needed intermittently when pain is not controlled by Paracetamol and Ibuprofen. Please take the prescribed dose as directed. This medication can cause drowsiness and constipation.
  • If you have any queries about pain relief requirements, please contact our practice.


Non-Medication Pain Relief

There is some evidence that the following measures may aid in pain relief after tonsil surgery:

  • Maintain hydration to keep the mouth moist;
  • Use chewing gum and/or chewy lollies to exercise the jaw. It works like physio for your mouth;
  • Ice blocks, ice-cream and other cool items can alleviate pain in the first few days after surgery; and
  • A varied diet including some harder to swallow items (bread/meat/apples and whole fruit) speeds up the healing process by ‘cleaning’ the operation site.


There are no restrictions on diet. Children are encouraged to drink as much as required, to avoid dehydration. Ice blocks are a good option as they are soothing and help with hydration. 

If your child refuses solids but is maintaining good fluid intake, then this is acceptable.  At least 80mls fluids per kilo body weight each day is recommended.

Please contact our Practice if your child is not drinking or eating enough. They may need to be re-admitted to hospital for intravenous fluids.


In certain circumstances, children may be prescribed antibiotics following surgery. Please take as instructed if advised. For most children, antibiotics will not be necessary.


It is common to have a mild fever for the first 24-48hrs after the operation.  Please call our Practice or see your GP if there is a persistent fever greater than 38.5°C.

Bad Breath

Bad breath is expected following removal or tonsils and even more so if the adenoids are removed.  It is part of the normal healing process. This usually settles after around 3 weeks, if not sooner.


If there is any sign of fresh bleeding from the nose or mouth greater than a teaspoon in volume, please present to the nearest Emergency Department for assessment.

It is important to stay within 1 hour of a health service with an ENT surgeon for 7 days after tonsillectomy due to the risk of bleeding. While extremely rare, a severe post-tonsillectomy bleed can be a life-threatening event and will require an adequately staffed hospital to address the bleeding.

Follow Up appointment

A follow-up phone call is usually made 4-6 weeks after surgery in most cases. Where an appointment is needed you will be advised by your Surgeon. If at any stage, you wish to see your Surgeon, our staff will be happy to arrange an appointment.
