Adenoidectomy

Table of Contents

Adenoidectomy Introduction

An adenoidectomy is a surgical procedure to remove the adenoids, which are small pads of lymphatic tissue located at the back of the nose, above the roof of the mouth. Adenoids are part of the immune system and help fight infection, particularly in young children. However, in some cases, they can become enlarged or frequently infected, leading to breathing difficulties, recurrent ear or sinus infections, and sleep problems including snoring and obstructive sleep apnoea (OSA).

Adenoidectomy is a common and safe procedure, most often performed in children. It is sometimes done on its own or in combination with other procedures such as tonsillectomy or grommet insertion.

Reasons for surgery

You or your child may be recommended for adenoidectomy if they have:

  • Enlarged adenoids causing:
    • Blocked nose
    • Mouth breathing
    • Snoring or noisy breathing
    • Sleep disturbance or sleep apnoea (pauses in breathing at night)
  • Recurrent ear infections or glue ear (fluid behind the eardrum), especially if grommets are also being considered
  • Frequent or persistent nasal infections
  • Ongoing sinus problems not responding to medication
  • Speech or feeding issues related to adenoid enlargement

In many cases, adenoids naturally shrink as children grow older. However, if they are causing significant symptoms, surgery may be the best option.

Benefits of the procedure

  • Improved breathing through the nose
  • Better sleep quality and reduced snoring
  • Fewer sinus and ear infections
  • Less nasal congestion and discharge
  • Reduced need for antibiotics or other medications

Risks & complications

Adenoidectomy is a low-risk procedure, but as with any surgery, there are potential complications, including:

  • Bleeding (very rare)
  • Infection
  • Temporary bad breath or nasal discharge
  • Changes in speech (nasal sounding voice – usually temporary) or Velopharyngeal insufficiency (VPI)
  • Damage to eustachian tube
  • Rarely, regrowth of adenoid tissue
  • Reaction to anaesthetic

Dr Phillips will discuss these risks with you before surgery and answer any specific questions you may have.

Alternative treatments

For mild symptoms, alternative treatments may include:

  • Nasal saline sprays or rinses
  • Steroid nasal sprays
  • Antibiotics for infections
  • Watchful waiting, especially if your child is likely to outgrow the problem

If conservative treatments are ineffective or the symptoms are severe, surgery is often the most effective solution.

Pre-operative instructions

Medications

Let Dr Phillips know about any medications or supplements you or your child is taking as they may need to be stopped before surgery.

Fasting

If general anaesthesia is planned, you or your child must not eat or drink for a specific time before surgery (usually 6 hours for food, 2 hours for clear fluids). Follow the hospital’s fasting instructions carefully.

Illness

If you or your child develops a cold, fever, or other illness before the scheduled procedure, let the clinic know. Surgery may need to be postponed.

Procedure details

  • Adenoidectomy is done under general anaesthesia, meaning you or your child will be asleep and won’t feel any pain during the operation.
  • The adenoids are removed through the mouth – there are no external cuts or scars.
  • The procedure typically takes 15 to 30 minutes and is often combined tonsillectomy or cautery of inferior turbinates.
  • Bleeding is controlled at the time of surgery, and your child will be monitored in recovery before going home.

Post-operative care & recovery

Hospital Stay

Most patients go home the same day, usually a few hours after surgery.

Pain and Discomfort

  • Adenoidectomy usually causes less pain than a tonsillectomy.
  • You or your child may have a sore throat, ear pain, or stiff neck for a few days.
  • Regular paracetamol or ibuprofen can help manage discomfort.

Eating and Drinking

  • It is important to drink plenty of fluids.
  • There are no diet restrictions

Bad Breath (Halitosis)

  • This is expected following the removal of adenoids and is normal. Bad breath usually settles around 3 weeks, if not sooner.

Nasal Care

  • Mild nasal congestion and discharge are common for a few days to a week.
  • Avoid blowing the nose forcefully for the first few days.

Activity

  • You or your child should rest at home for 3-5 days.
  • Avoid strenuous activity, sports, or swimming for 1 to 2 weeks.
  • Return to school or work is usually possible at 1 week, depending on recovery.

What to watch for

Contact our clinic or seek medical attention if you or your child experiences:

  • Heavy or persistent bleeding
  • High fever (above 38.5°C)
  • Difficulty breathing
  • Signs of dehydration (dry mouth, reduced urine output)
  • Severe pain not relieved by medication

Follow-up instructions

You will usually have a follow-up telehealth appointment with Dr Phillips around 4 weeks after surgery to check on healing and ensure there are no ongoing issues.

Frequently asked questions (FAQ)

  • Will removing the adenoids weaken my child’s immune system?

    No. The adenoids are part of the immune system, but their removal does not increase the risk of infections. Other tissues in the body take over their role.

  • Can adenoids grow back?

    In rare cases, a small amount of adenoid tissue can regrow, but it rarely causes symptoms again or requires further surgery.

  • Will my child’s voice change after surgery?

    Some children have a slightly nasal-sounding voice after surgery. This is usually temporary and resolves within a few weeks.
