Adenoidectomy

Introduction

If your child — or you — has been recommended an adenoidectomy, you likely already know the background story. There may have been months or years of mouth breathing at night, heavy snoring, repeated ear infections, fluid behind the eardrum that affected hearing, or persistent blocked-nose breathing that did not get better with medication. After trying conservative care, an ENT (ear, nose, and throat) doctor has now suggested removing the adenoids.

This guide is written for that next stage. It explains what adenoidectomy is, how the surgery is performed, what recovery looks like, what risks to be aware of, and what life typically looks like in the weeks and months afterward. Most readers will be parents of a child who is scheduled for surgery, but the article also covers adults, for whom the procedure is less common but sometimes appropriate.

Adenoidectomy is one of the most frequently performed surgeries in children worldwide. It is generally safe, short, and well tolerated. Understanding what is involved helps reduce anxiety on the day and supports a smoother recovery at home.

What Is Adenoidectomy?

An adenoidectomy is a surgical procedure to remove the adenoids. The adenoids (also called the pharyngeal tonsil) are a small pad of lymphatic tissue that sits high at the back of the nose, just above the soft palate, in a space called the nasopharynx. You cannot see the adenoids by looking into the mouth — they are tucked behind the nose.

The adenoids are part of the body’s immune system in early childhood. They help the body recognise germs that enter through the nose and mouth. They are typically largest between the ages of about three and seven, and then naturally shrink during later childhood and adolescence. By adulthood, the adenoids are usually very small or absent.

Sometimes, however, the adenoids stay enlarged or become repeatedly inflamed. When this happens, they can block the back of the nose, interfere with normal drainage from the middle ear (through a passage called the Eustachian tube), and contribute to chronic infection. In these situations, removing the adenoids can relieve the obstruction and reduce the cycle of infection.

The surgery is performed through the open mouth while the patient is asleep under general anaesthesia. There are no cuts on the face or neck, and no visible scars. Most adenoidectomies take about 20 to 30 minutes, and most patients go home the same day.

Why Is Adenoidectomy Performed?

Doctors consider adenoidectomy when enlarged or chronically inflamed adenoids are clearly contributing to symptoms that affect breathing, sleep, hearing, or quality of life, and when those symptoms have not improved enough with conservative treatment. The main reasons it is recommended include:

Sleep-disordered breathing and obstructive sleep apnoea

This is one of the most common reasons for adenoidectomy in children today. Enlarged adenoids (often together with enlarged tonsils) can narrow the airway during sleep, causing loud snoring, gasping, restless sleep, mouth breathing, and in some children, brief pauses in breathing — a pattern called obstructive sleep apnoea (OSA). Untreated childhood OSA can affect daytime behaviour, attention, school performance, and growth. The American Academy of Pediatrics and ENT guidelines describe adenotonsillectomy (removing both adenoids and tonsils) as a first-line surgical treatment for childhood OSA when enlarged tissue is the cause.

Chronic nasal obstruction and mouth breathing

Persistent blockage at the back of the nose can force a child to breathe through the mouth day and night. Over time, chronic mouth breathing may contribute to changes in facial growth and dental alignment in some children. Removing obstructive adenoids can restore normal nasal airflow.

Glue ear (otitis media with effusion) and recurrent ear infections

The adenoids sit close to the openings of the Eustachian tubes, which equalise pressure and drain fluid from the middle ear. When adenoids are enlarged or infected, they can interfere with this drainage, contributing to fluid buildup behind the eardrum (glue ear) and repeated ear infections. Hearing can be affected, which in young children may also affect speech development. Adenoidectomy is sometimes performed at the same time as the placement of ventilation tubes (grommets) in the eardrums, particularly when a child has had repeated episodes or persistent hearing loss.

Chronic or recurrent sinusitis

In some children, enlarged adenoids act as a reservoir for bacteria and contribute to repeated sinus infections. When sinusitis is frequent and has not responded to medical treatment, adenoidectomy may be considered.

Chronic adenoiditis

Repeated infection of the adenoid tissue itself — with persistent post-nasal drip, bad breath, and nasal congestion — may be a reason for surgery if it does not settle with medical care.

Who Is a Candidate?

Not every child with enlarged adenoids needs surgery. Many children grow out of the problem as the adenoids shrink naturally. Doctors generally consider adenoidectomy when:

• Symptoms are persistent or recurrent and significantly affect sleep, hearing, breathing, or daily life
• Conservative treatment — such as saline nasal sprays, treatment of allergies, nasal steroid sprays, or appropriate antibiotic courses for infection — has been tried and has not given enough benefit
• Examination (usually with a small flexible camera passed through the nose, called nasal endoscopy) confirms that the adenoids are enlarged and likely the cause
• Sleep study findings, hearing tests, or repeated documented infections support the clinical picture

Most candidates are children between roughly two and ten years of age. Adenoidectomy can be considered in younger children when symptoms are severe, but the threshold is generally higher because adenoid tissue often shrinks naturally with age.

For adults, the picture is different. The adenoids are usually small by adulthood, so adenoidectomy is less common. It may still be considered in adults with persistent adenoid enlargement on imaging or endoscopy, ongoing nasal obstruction, or, less commonly, when a sample of the tissue is needed to investigate other concerns.

Alternatives to Adenoidectomy

Before surgery, doctors typically try non-surgical approaches, particularly when symptoms are mild or moderate. Alternatives and adjuncts that may be discussed include:

Watchful waiting

Because adenoids naturally shrink with age, mild symptoms may be monitored over time, particularly in older children. A “wait and see” approach is appropriate when symptoms are not significantly affecting sleep, hearing, or daily life.

Treating underlying allergies

Allergic rhinitis (hay-fever-type nasal allergy) can cause symptoms similar to enlarged adenoids and can also make adenoid tissue swell. Treating allergies with antihistamines, allergen avoidance, or allergy-focused care can sometimes reduce symptoms enough that surgery is not needed.

Intranasal corticosteroid sprays

Studies have shown that nasal steroid sprays can reduce adenoid size and symptoms in some children. A trial of several weeks is sometimes used before deciding on surgery, particularly when symptoms are moderate.

Saline rinses and good nasal hygiene

Regular saline nasal sprays or rinses help clear mucus and may reduce mild congestion. They are commonly used alongside other treatments.

Targeted treatment of infection

If repeated bacterial infections are the main concern, a doctor may try a longer or different course of antibiotic before considering surgery.

Ventilation tubes (grommets) alone

For glue ear with hearing loss, ventilation tubes may be placed in the eardrums without adenoidectomy in some cases, particularly at a first procedure. Adding adenoidectomy is more often considered when glue ear comes back after grommets, or when there are also significant nasal symptoms.

Whether any of these alternatives is appropriate depends on the specific pattern of symptoms, the child’s age, the findings on examination, and the doctor’s assessment.

Surgical Approaches and Techniques

All adenoidectomies are performed through the mouth, with the patient asleep, and without any external cut. What varies is the instrument the surgeon uses to remove the adenoid tissue. Each technique has the same goal, and outcomes are broadly similar across modern methods. The surgeon usually chooses based on training, the individual case, and the equipment available.

Curettage (the traditional method)

A curved instrument called an adenoid curette is passed behind the soft palate to scrape away the adenoid tissue. Bleeding is then controlled with pressure or cautery. This is a long-established technique and is still widely used.

Suction coagulation (suction diathermy)

A specialised suction device with electrical cautery is used to gently melt away the adenoid tissue while controlling bleeding at the same time. It is commonly used and allows good visual control.

Microdebrider adenoidectomy

A small powered shaver device removes the tissue in a precise, controlled manner under direct vision. It can allow more accurate removal in difficult-to-reach areas.

Coblation

This method uses radiofrequency energy at relatively low temperatures to remove the adenoid tissue. Supporters describe it as gentle on surrounding tissue.

If you are not sure which technique your surgeon plans to use, it is reasonable to ask. The choice does not usually change recovery significantly.

Combined adenoidectomy and tonsillectomy (adenotonsillectomy)

In many children, particularly those with sleep-disordered breathing or obstructive sleep apnoea, the tonsils are also enlarged and contributing to airway obstruction. In these cases, the surgeon may remove both at the same time. This is called an adenotonsillectomy. Recovery after combined surgery is usually slower and more uncomfortable than after adenoidectomy alone, mainly because tonsillectomy involves a more painful throat healing process. If both procedures are being considered, the surgeon will explain why.

Preparing for Adenoidectomy

The preparation steps are similar for children and adults, with extra attention to age-appropriate explanation and emotional support for younger children.

Pre-operative consultation

Before surgery, the ENT specialist will confirm the diagnosis, review the medical history, and explain the procedure. Tell the team about:

• Any allergies, especially to medications
• Current medications, including over-the-counter and herbal products
• Any bleeding problems in the child or in close family members
• Recent illnesses, particularly fevers, coughs, or colds in the past two weeks
• Any previous problems with anaesthesia in the child or family

Routine pre-operative checks are usually arranged. These may include basic blood tests and, in some cases, a hearing test or sleep study, depending on the reason for surgery.

Fasting instructions

Because the surgery is done under general anaesthesia, the stomach must be empty. The hospital will give specific instructions about when to stop eating and drinking before the operation. These are important for safety and should be followed exactly. Typically, solid food is stopped several hours before, with clear fluids allowed until a defined cut-off.

Medication adjustments

Some medications that affect bleeding — such as aspirin, ibuprofen, and certain herbal supplements — may need to be stopped for a period before surgery. Your surgeon will give specific guidance. Regular medicines for conditions such as asthma or epilepsy are usually continued; check with the team.

Preparing a child for the day

For a child, simple, honest explanation is usually best. Things that may help:

• Explain that the doctor will help them sleep, then take out something inside that has been making it hard to breathe and sleep well
• Reassure them that there will be no cuts on the outside
• Bring a favourite toy, book, or comfort item to the hospital
• Pack soft clothes that are easy to change into
• Plan for at least one parent to stay with the child before and after the procedure

If the child or adult is unwell on the day

If there is a fever, an active cold, or a chest infection on the day of surgery, the operation may be postponed. This is to reduce anaesthetic and breathing risks. Let the team know in advance if anything changes.

What Happens During the Procedure

On the day of surgery, the family arrives at the hospital or day-surgery unit at the time given. The team will check identification, confirm the procedure, review fasting, and weigh the child.

Anaesthesia

An anaesthetist (a doctor specialised in anaesthesia) will meet the patient and family before the operation. General anaesthesia is given so the patient is fully asleep and feels nothing during the surgery. In young children, this is often started using a mask with anaesthetic gas, and a small intravenous (IV) line is placed once the child is asleep. In older children and adults, the IV line is often placed first.

The operation

Once the patient is asleep, the surgeon places a small instrument that holds the mouth open. The surgeon then works through the open mouth, using a small mirror or an angled endoscope to see the adenoid tissue behind the soft palate. The adenoids are removed using the technique chosen (curettage, suction coagulation, microdebrider, or coblation). Any bleeding is carefully controlled.

The procedure itself usually takes about 20 to 30 minutes. If grommets or tonsillectomy are being done at the same time, the total time is longer.

After the operation

The patient is moved to a recovery area and watched closely as the anaesthesia wears off. Children sometimes wake up disoriented or upset; this usually settles quickly with a parent present. Vital signs (heart rate, breathing, oxygen levels) are monitored. Pain relief and anti-nausea medicines are given as needed.

Most patients are well enough to go home the same day, usually a few hours after the procedure. Some children — especially very young children, those with severe sleep apnoea, or those with other medical conditions — may be kept in hospital overnight for observation.

Recovery and Healing

Recovery from adenoidectomy alone is generally quick and uncomplicated. Recovery is slower when tonsillectomy has been done at the same time.

The first 24 to 48 hours

Expect some throat discomfort, a sore neck, mild ear pain (referred pain from the surgical area), bad breath, and a temporary blocked or runny nose. There may be a small amount of blood-tinged mucus from the nose. A low-grade fever in the first day or two is common and usually settles with paracetamol.

Encourage:

• Plenty of cool fluids — water, diluted juice, ice lollies
• Soft foods such as yoghurt, mashed potato, soft pasta, soft fruit, scrambled egg, or porridge
• Rest at home
• Pain relief on a regular schedule for the first day or two, as advised by the surgical team

The first week

Most children feel substantially better within three to five days. Bad breath is common during the first week as the area heals; this is normal and does not mean infection. The voice may sound slightly different — sometimes more nasal — for a few days to a couple of weeks, as the soft palate and nasopharynx adjust. Most children return to school and normal activity within about a week.

Beyond the first week

Pain control

Paracetamol is the usual first-line pain reliever after adenoidectomy. Ibuprofen may be used as advised, but some surgeons prefer to avoid medications that affect bleeding in the first few days. Aspirin is generally avoided in children. Follow the specific instructions the team gives at discharge.

When to contact the surgical team

Get in touch with the surgical team or seek urgent care if there is:

• Bright red bleeding from the nose or mouth that does not stop within a few minutes
• A fever above 38.5 °C / 101 °F that does not settle with paracetamol
• Persistent vomiting
• Inability to drink fluids, signs of dehydration (very little urine, dry mouth, sunken eyes, drowsiness)
• Severe pain that is not controlled by the prescribed medicines
• Difficulty breathing or persistent very loud noisy breathing

Risks and Complications

Adenoidectomy is considered a low-risk operation, especially compared with many other surgeries. Still, every operation has some risk, and it is worth being aware of them.

Common, usually minor effects

• Sore throat and mild ear pain for a few days
• Temporary change in voice quality (often described as a more nasal sound)
• Bad breath during healing
• Temporary blocked nose or blood-tinged nasal discharge
• Nausea after anaesthesia

Less common complications

• Bleeding. Significant bleeding is uncommon but can occur, either soon after surgery or, less often, several days later as healing tissue settles. In rare cases, a return to the operating theatre is needed to control bleeding.
• Infection. Infection of the surgical area is uncommon and usually responds to antibiotics.
• Velopharyngeal insufficiency. In a small number of cases, the soft palate does not fully close off the nose during speech after adenoid removal, leading to a nasal-sounding voice or air escape through the nose when speaking. This is usually temporary, but in a small number of patients it persists and may require speech therapy or, rarely, further treatment. The risk is higher in children with an undiagnosed cleft palate or submucous cleft, which the surgeon checks for before deciding to operate.
• Nasal regurgitation. Some patients notice food or liquid coming up into the nose for a short time after surgery. This usually settles as healing completes.
• Anaesthetic risks. Modern general anaesthesia is very safe, but, as with any anaesthetic, there are small risks of reactions and breathing problems. The anaesthetist will discuss these.
• Regrowth of adenoid tissue. A small amount of adenoid tissue can sometimes grow back, particularly in very young children, and very rarely a repeat procedure is needed.

Overall, serious complications are uncommon. Most children come through the operation without significant problems.

Life After Adenoidectomy

For most children, the change after recovery is noticeable and welcome. Parents commonly describe:

• Quieter sleep, with less or no snoring
• Easier breathing through the nose, often for the first time the child can remember
• Fewer ear infections
• Better hearing if glue ear was a problem (especially when grommets have been added)
• Improved sleep quality, sometimes followed by improvements in daytime behaviour, concentration, and mood
• Better appetite and weight gain in children whose sleep had been disturbed

Some changes appear within days; others take weeks to become obvious as inflammation in the upper airway settles and the body adjusts.

Does removing the adenoids weaken the immune system?

This is one of the questions parents ask most often. The short answer is no. The adenoids are one small part of a much larger immune system that includes lymph nodes, the spleen, the bone marrow, and many other tissues. After the adenoids are removed, the rest of the immune system continues to protect against infection. Studies have not shown a meaningful long-term increase in infection rates in children who have had their adenoids removed for appropriate medical reasons.

Follow-up

A follow-up appointment is usually scheduled a few weeks after surgery. The surgeon checks healing, asks about symptoms, and, if hearing was affected before, may arrange a repeat hearing test. Most children do not need long-term follow-up beyond this. If symptoms come back, or if grommets were placed, further visits may be planned.

Adenoidectomy in Adults

Adenoidectomy is much less common in adults because the adenoids usually shrink to a small size by the end of adolescence. When it is performed in adults, the reasons may include:

• Persistent adenoid enlargement causing nasal obstruction or snoring
• Chronic adenoid infection that has not responded to medical treatment
• Suspicious appearance or growth of nasopharyngeal tissue that requires a tissue sample (biopsy), in which case the procedure is partly diagnostic
• Adenoid tissue contributing to recurrent sinus problems or ear problems in selected cases

The procedure in adults is similar in technique to that in children, but adults sometimes find recovery slightly more uncomfortable, with throat pain and ear ache lasting a few days longer. Most adults can return to office-type work within about a week.

Frequently Asked Questions

How long does the operation take?

The adenoidectomy itself usually takes about 20 to 30 minutes. The total time at the hospital is longer, because it includes admission, anaesthesia, and recovery before going home — usually a few hours in all.

Will my child have stitches?

No external stitches. The area inside the nasopharynx is left to heal on its own; it does not usually require stitches.

How long will my child be in hospital?

Most children go home the same day. An overnight stay may be advised for very young children, those with significant sleep apnoea, or those with other medical conditions.

When can my child go back to school?

Most children are ready to return to school within about a week, once they are eating, drinking, sleeping, and behaving close to normal. If tonsillectomy was done at the same time, the time away from school is usually longer — around two weeks.

Why does my child have bad breath after surgery?

Bad breath during the first one to two weeks is common and is part of normal healing. It is not a sign of infection by itself. Plenty of fluids and gentle oral hygiene help. If it is associated with fever, severe pain, or worsening symptoms, contact the surgical team.

Will my child’s voice change?

A temporary change in voice quality — often a slightly more nasal sound — is common in the first few days to weeks. In most children it settles as the area heals. A small number of children develop a longer-lasting nasal-sounding voice, which may benefit from speech therapy.

Can the adenoids grow back?

A small amount of regrowth is possible, particularly in younger children, but significant regrowth that requires repeat surgery is uncommon.

Will the snoring stop straight away?

Many parents notice quieter breathing within days. Final results are usually clear within a few weeks, once swelling has fully settled. In some children — especially those who also had enlarged tonsils — the change is dramatic.

What is the difference between adenoidectomy and tonsillectomy?

The adenoids are behind the nose; the tonsils are at the back of the mouth on either side of the throat. They are different tissues. Sometimes one is removed; sometimes both are removed in the same operation, called adenotonsillectomy. The decision depends on which tissue is causing problems.

Is adenoidectomy painful?

There is usually some throat discomfort and mild ear pain for a few days, but pain after adenoidectomy alone is generally much less than after tonsillectomy. Simple pain relief such as paracetamol is usually enough.

Conclusion

Adenoidectomy is a short, common, and well-established operation. For the right reasons — persistent nasal obstruction, sleep-disordered breathing, glue ear, or recurrent ear and sinus infections that have not improved with other care — it can make a real difference to a child’s breathing, sleep, hearing, and overall wellbeing. Recovery is usually quick, and most children are back to normal life within a week.

If your child has been recommended adenoidectomy, the most useful next steps are to understand the specific reason it has been suggested, ask the ENT team any questions that remain — about technique, recovery, what to look out for at home — and prepare practically for the day of surgery and the week that follows. With clear information and good support around the operation, families generally come through the experience smoothly and see lasting benefit.
