Paediatric ENT · London
Adenoidectomy, by a paediatric ENT surgeon.
A short day-case operation to remove the adenoid pad in children with snoring, sleep apnoea, glue ear or recurrent adenoiditis. Done by a consultant paediatric ENT surgeon with a paediatric anaesthetist, in a unit set up for children. Home the same day, no external scar.
Indicative pricing
What a private adenoidectomy costs in London.
Indicative ranges across our partner units. Send the symptoms and any prior oximetry or audiology, and we quote firm figures across two or three options.

The journey
From first message to two-week review, what happens, in order.
One team from your first enquiry through consultation, day surgery and the nurse-led follow-up.
- 01
Before
You send us the symptoms
A short, confidential form. Snoring, witnessed apnoea, mouth breathing, ear infections, glue ear, growth or behaviour concerns, and any prior audiology or oximetry.
- 02
Before
We come back with a plan
Within one working day: whether adenoidectomy alone fits, or whether tonsillectomy or grommets should go on the same list. Indicative price. An honest read either way.
- 03
Before
Paediatric ENT clinic visit
Examination of the adenoid pad and tonsils (Brodsky grade), tympanogram and audiology for glue ear, and home overnight oximetry if paediatric OSA is suspected.
- 04
On the day
Arrival at the day unit
A play-friendly paediatric ward. Consent, weight and pre-op checks with the ENT surgeon and paediatric anaesthetist. Parent to induction in most units.
- 05
On the day
The adenoidectomy
15 to 20 minutes under GA, supine with head extended and a Boyle-Davis retractor. No external scar. Suction diathermy is the modern standard.
- 06
On the day
Home the same day
Short paediatric recovery, written aftercare, and home within a few hours. Cool, soft food for 5 to 7 days. Back to school in 5 to 7 days.
- 07
After
Two-week telephone review
A nurse-led call to check bleeding, feeding, snoring resolution and hyponasal speech. Face-to-face follow-up if grommets were placed or hearing was borderline.
When it helps
When adenoidectomy is the right step.
The clinical patterns that most often lead to surgery. Also assessed: allergic rhinitis on skin-prick testing, which is treated medically first rather than surgically.
-
Chronic mouth breathing and hyponasal voice
A blocked nose that never clears, a permanently open mouth and a muffled, blocked-nose voice - classic adenoid hypertrophy.
-
Snoring and paediatric OSA
Loud nightly snoring, witnessed apnoeas, restless sleep and daytime tiredness or hyperactivity that can mimic ADHD.
-
Recurrent glue ear (OME)
Persistent middle-ear effusion causing conductive hearing loss, delayed speech and school difficulties, often better after the adenoids come out.
-
Recurrent adenoiditis
Repeated episodes of purulent post-nasal discharge, halitosis and low-grade fever failing medical therapy.
-
Recurrent otitis media
Repeated ear infections in a child under seven where the adenoid pad is acting as a bacterial reservoir.
-
Failure to thrive and growth failure
A child dropping across weight centiles because sleep-disordered breathing is disturbing growth-hormone secretion.
-
Behaviour and school problems
Poor sleep from adenoidal obstruction driving inattention, irritability and hyperactivity that resolve after surgery.
-
Red flag: severe OSA with desaturations
Documented severe paediatric OSA needs prompt paediatric ENT input and a unit with overnight paediatric observation, not a routine day list.
Procedure options
Adenoidectomy is a family of techniques.
What each option on the table actually involves, and which fits which child. Combined operations are common: see our combined adenotonsillectomy page for that pathway.
-
Cold curettage adenoidectomy
The traditional St Clair Thompson curette with a post-nasal gauze pack. Quick and cheap, but higher rate of residual adenoid tissue and recurrence.
-
Suction diathermy adenoidectomy
Monopolar suction diathermy under mirror or endoscopic view. The modern UK standard: less bleeding, better haemostasis and lower recurrence.
-
Coblation adenoidectomy
Plasma-field dissection at low temperature. Precise, less thermal spread and useful for larger adenoid pads or when tonsils are also being removed.
-
Microdebrider adenoidectomy
A powered suction shaver removes adenoid tissue under direct endoscopic view. Precise and preserves nearby structures such as the eustachian tube openings.
-
Endoscopic-assisted adenoidectomy
A 70 or 90 degree endoscope gives direct visualisation of the nasopharynx. The best option for re-do surgery or when residual choanal adenoids are suspected.
-
Combined adenotonsillectomy (ATT)
For children with combined tonsil and adenoid hypertrophy driving OSA, both are done on the same list. See our combined adenotonsillectomy page.
-
Adenoidectomy with grommets
Combined with myringotomy and grommet insertion for glue ear with hearing loss. Halves the risk of a second grommet operation later.
-
NHS versus private
NHS remains available for OSA, glue ear and recurrent infection. Private routes are chosen for a named consultant and a shorter wait, often within 1 to 2 weeks.

Safety and recovery
What to expect afterwards, honestly.
Adenoidectomy is one of the most common paediatric ENT operations in the UK. The things worth planning are the diet, the two-week bleeding window and the return to school.
-
A short, well-tolerated day case
About 15 to 20 minutes under general anaesthetic with a paediatric anaesthetist. Home within a few hours. No external scar and no stitches to worry about.
-
Postoperative bleeding
Uncommon (under 2%), usually self-limiting. Primary bleeding within 24 hours, or secondary bleeding at 5 to 10 days. Any fresh red bleeding is an A&E trip.
-
Temporary hyponasal speech
For 2 to 4 weeks the voice can sound less blocked and slightly different as the palate adapts. Almost always settles without any speech therapy.
-
Velopharyngeal insufficiency (VPI)
Rare (about 1%) persistent hypernasal speech from poor palate closure. Higher risk in children with a submucous cleft or a bifid uvula - screened for pre-op.
-
Dehydration if poor oral intake
Some children eat little on day 1. Cool fluids, ice lollies and soft food (yoghurt, mashed potato, pasta) protect against dehydration.
-
Recovery expectations
Back to school in 5 to 7 days. Avoid contact sport, swimming and flying for 2 weeks. Soft cool diet for 5 to 7 days. Regular paracetamol and ibuprofen as directed.
-
Grisel syndrome (very rare)
Atlanto-axial subluxation after nasopharyngeal surgery. Extremely rare; presents with fever, neck pain and torticollis in the first 2 weeks and needs urgent review.
-
Realistic outcomes
Around 90 to 95% of children see clear resolution of snoring, OSA symptoms or glue ear where the adenoid was the driver. Recurrence 2 to 5% with modern suction diathermy versus 10 to 15% with cold curettage.
-
Red flags after discharge
Fresh red bleeding from the nose or mouth, a fever above 38.5C beyond day 3, refusing all fluids, or a stiff painful neck. Call the unit or attend A&E.
Reading the operation note
The operation note in four parts. Read the last one first.
Whichever technique was used, the note the surgeon sends home keeps to the same shape.
- 01 Header
Indication and pre-op findings
Why the operation was recommended: snoring, OSA, glue ear or recurrent infection, adenoid size and tonsillar Brodsky grade, and pre-op oximetry or audiology.
- 02 Technique
How the adenoids were removed
Whether suction diathermy, coblation, microdebrider or cold curettage was used, and whether grommets or tonsillectomy were done at the same time.
- 03 Findings
Intra-operative findings
The adenoid grade, any residual choanal tissue, middle-ear effusion at myringotomy, and any anatomical notes such as a submucous cleft.
- 04 Impression
Aftercare and follow-up plan
Read this first: diet advice, return to school, red-flag bleeding advice, and whether an audiology or oximetry follow-up is booked.
Recognised by major UK insurers
Cover for paediatric adenoidectomy varies by insurer and by indication, usually funded when medically indicated. We confirm cover before booking.
Frequently asked
Everything parents ask us about adenoidectomy.
Quick answers on anaesthetic, recovery, cost, combined operations and how likely symptoms are to come back.
-
What is an adenoidectomy and why does my child need one?
Adenoidectomy is the removal of the adenoid pad at the back of the nose. It is offered to children with obstructive sleep apnoea from adenoid hypertrophy, chronic mouth breathing, glue ear with hearing loss, or recurrent adenoiditis and ear infections. It is one of the most common paediatric ENT operations in the UK.
-
How long does it take and is there a scar?
The operation itself takes 15 to 20 minutes under a general anaesthetic, done through the mouth with a Boyle-Davis retractor. There is no external cut and no stitches, so no visible scar. Total time in the day unit is usually 4 to 6 hours.
-
How much does a private adenoidectomy cost in London?
Roughly £2,400 to £4,500 for adenoidectomy alone as a day case. Combined adenotonsillectomy is £3,500 to £5,500 and combined adenoidectomy with grommets for glue ear is £4,500 to £7,500. A consultation is £250 to £400. We confirm a firm figure within one working day.
-
How long is recovery and when can my child go back to school?
Most children are back to school in 5 to 7 days. A cool soft diet for the first week, regular paracetamol and ibuprofen, and no contact sport, swimming or flying for 2 weeks. The voice can sound slightly different (hyponasal) for a few weeks and then settles.
-
Will my child need tonsils out or grommets at the same time?
Not always. If the tonsils are large and contributing to obstructive sleep apnoea, a combined adenotonsillectomy is the better operation. If your child has glue ear with hearing loss, grommets are commonly added, which halves the chance of needing a second operation later. The paediatric ENT surgeon decides based on the clinical picture and any oximetry or audiology.
-
How likely is the snoring, glue ear or ear infections to come back?
Around 90 to 95% of children see clear improvement in snoring, sleep-disordered breathing or glue ear symptoms when the adenoid was the main driver. Recurrence of adenoid tissue is 2 to 5% with modern suction diathermy or coblation techniques, compared with 10 to 15% after older cold curettage. Re-do surgery is uncommon.
