Tonsillectomy and Adenoidectomy in Children: What to Expect

Tonsillectomy removes the tonsils; adenoidectomy removes the adenoids. Recovery takes one to two weeks and requires careful pain management. Dehydration and post-operative bleeding are the most important complications to watch for.

The two main reasons children have this surgery

Recurrent infections: Current ENT guidelines suggest watchful waiting when there have been fewer than 7 episodes of throat infection in the past year, fewer than 5 per year in the past 2 years, or fewer than 3 per year in the past 3 years 1. When a child's documented infection history exceeds these thresholds and the episodes are severe — requiring antibiotics, causing missed school, or affecting quality of life — tonsillectomy may be considered.

Airway obstruction and sleep-disordered breathing: Enlarged tonsils and adenoids are the most common cause of obstructive sleep apnea (OSA) in children 2. Symptoms include loud snoring, observed breathing pauses during sleep, restless sleep, mouth breathing, and sometimes behavioral or attention problems linked to poor sleep quality. For children with significant OSA, adenotonsillectomy is well-supported by evidence and may result in marked improvement in sleep quality and daytime functioning 2.

What happens during surgery

The procedure is done under general anesthesia. The tonsils are removed through the open mouth; no external cuts are made. Adenoids, which sit higher up behind the nose, are also removed through the mouth using instruments. The whole procedure typically takes 20 to 45 minutes.

Most healthy children go home the same day. Children with significant sleep apnea, very young children (typically under age 3), children with obesity, or those with other medical considerations may be observed overnight as a safety precaution 1.

Recovery: what the first two weeks look like

Recovery from tonsillectomy is often more uncomfortable than families expect. Throat pain typically peaks around days 4 through 6 — sometimes getting worse before it gets better — as the surgical scab (eschar) forms and then begins to dissolve around days 10 to 14 1.

Pain management is the central task at home. The surgical team will advise on a pain plan; current guidelines recommend against codeine or any codeine-containing medication in children under 18 after tonsillectomy because of safety concerns 1. Staying ahead of pain (giving medication on a regular schedule rather than waiting for pain to spike) helps children stay comfortable and — critically — continue to drink fluids.

Cool, soft, and smooth foods and drinks are easiest to swallow: popsicles, ice chips, water, cold or lukewarm broths, yogurt, pudding, and soft pasta.

Hydration and the scab — the most important home management points

Keeping a child well-hydrated after tonsillectomy is not optional — it is the key to avoiding complications. Dehydration is the most common complication requiring a return visit or readmission 1. Families should track whether the child is drinking throughout the day and producing urine.

Around days 7 to 10, the white eschar (surgical scab) begins to fall away naturally. There may be a small amount of bleeding with this — but significant or ongoing bleeding is not normal and requires immediate attention. This is one reason activity restrictions (no vigorous exercise or straining) are maintained for the full two weeks.

Returning to school and activity

Most children return to school and light activity after 7 to 10 days, though some need the full two weeks. Contact sports, swimming, and vigorous physical activity are typically restricted for two weeks 1.

The voice may sound different during recovery — higher-pitched or slightly nasal — as the throat heals; this resolves on its own. Children who had significant airway obstruction before surgery often notice a dramatic improvement in sleep quality and energy within weeks. Families describe the change as transformative in many cases 2.

Common questions

Will my child be more likely to get sick after tonsils are removed?

The immune system does not rely on the tonsils and adenoids — they are a small part of a much larger immune network. Children who have these removed do not appear to have higher rates of serious infections afterward. For children who had airway obstruction, better sleep itself tends to improve overall health and daytime functioning.

When is it okay to stop the scheduled pain medication at home?

The surgical team will give specific guidance, but generally parents are advised to keep pain controlled on a schedule (not just when the child complains) for at least the first 5 to 7 days. Stopping too early — especially around the time the scab is dissolving — can lead to poor fluid intake and avoidable complications. Follow the instructions from the specific surgical team.

What if my child refuses to eat or drink after surgery?

Small, frequent sips are more manageable than large amounts at once. Cold beverages and popsicles are often easier than warm or room-temperature options. If a child is not producing urine, refuses all fluids, or seems very unwell, contact the surgical team. Dehydration requiring IV fluids is something the team wants to know about promptly.

When to get care right away

  • —Any bright red bleeding from the mouth after tonsillectomy — spitting or vomiting blood
  • —Difficulty breathing or swallowing that is worsening rather than improving
  • —Signs of significant dehydration: no urine for 8+ hours, no tears, dry mouth, listlessness
  • —Fever that is high or rising beyond the first day or two post-surgery
  • —Child is inconsolable or seems very ill

Post-tonsillectomy bleeding is a surgical emergency. If a child is actively bleeding from the mouth or throat, go to the emergency department immediately or call 911. Do not wait to see if it stops on its own.
