Indicative pricing

What a private ETS costs in the UK.

Indicative ranges across our partner thoracic units.

In short

£7,500–£11,500, home day-case or one night.

Procedure Indicative range
Bilateral ETS (R3 or R4, clipping) £7,500–£11,500
Bilateral ETS (division/cautery) £7,000–£10,500
Unilateral ETS (single hand or face) £5,000–£7,500
Thoracic surgeon consultation only £300–£500
Iontophoresis and botox before considering ETS £350–£900
Reversal attempt (clip removal) £8,000–£13,000

Prices vary by hospital, by the consultant, and by whether clipping or division is used. Reversal attempts sit at the top of the range because they take longer and require the original surgeon’s technique.

The problem

Honest counselling, the right level, and something to try first.

ETS is where cosmetic marketing quietly under-delivers - compensatory sweating minimised, non-surgical options skipped, cool-down periods waived. We fix all three before you consent.

  • Have you tried iontophoresis and botox?

    For most palmar and axillary sweating, non-surgical treatments should be exhausted first.

  • R4, not R3

    Modern practice is R4 for palmar hyperhidrosis - drier torso, less compensatory sweating. We only agree to R3 when the case genuinely needs it.

  • A cool-down that is real

    A minimum two weeks between consent and surgery. Regret after ETS is real and hard to reverse - hurrying benefits no one.

When it helps

When ETS is the right step.

The situations we see most, plus the one red flag that means endocrine and haematology workup first, not a surgical clinic.

  • Severe palmar hyperhidrosis

    Hands that drip, ruin paperwork or make handshakes miserable - after conservative measures have failed.

  • Severe axillary hyperhidrosis

    Underarm sweat that soaks through clothing daily, unresponsive to strong antiperspirants, iontophoresis, botox or miraDry.

  • Facial blushing and craniofacial sweating

    Disabling social blushing or scalp/forehead sweating - usually R2 sympathectomy, higher risk of compensatory sweating.

  • Plantar sweating (feet)

    ETS does not usually help feet. Lumbar sympathectomy is the equivalent operation - we refer if that is your main problem.

  • Failed non-surgical treatments

    You have tried aluminium chloride, iontophoresis, botox, oral anticholinergics - and still cannot function. That is when ETS earns its place.

  • Occupational impact

    Surgeons, musicians, teachers, salespeople whose work is genuinely limited - the calculus tilts toward ETS earlier.

  • Long QT and reflex sympathetic dystrophy

    Rare cardiac and pain indications where sympathectomy is used therapeutically rather than for sweating.

  • Red flag: sudden new sweating

    New-onset sweating with weight loss, night sweats or fever needs endocrine and haematology workup first - not ETS.

Procedure options

Approach and level both depend on the pattern.

What each option involves - clip or divide, R2, R3 or R4, bilateral or unilateral, and non-surgical alternatives.

  • Thoracoscopic clipping (R3 or R4)

    Titanium clips placed on the sympathetic chain - the workhorse. Theoretically reversible if compensatory sweating is intolerable, though reversal is not guaranteed.

  • Thoracoscopic division or cautery

    The chain is cut or burnt. Permanent. Slightly less rebound rate but no route back if compensatory sweating is severe.

  • R3 versus R4 level

    R4 gives drier palms with less severe compensatory sweating and is now the modern default for palmar hyperhidrosis. R3 is stronger but wetter feet and torso are more likely.

  • R2 for facial blushing

    Reserved for disabling social blushing. Compensatory sweating is more common at this level - patients must weigh it carefully.

  • Bilateral versus unilateral

    Almost always bilateral - one dry hand and one wet hand is uncomfortable. Unilateral is rare, for specific one-sided problems.

  • Uniportal versus two-port

    Some centres do it through a single small incision under each armpit. Cosmetic result is subtly better; functional result is the same.

  • Lumbar sympathectomy for feet

    A related but different operation for plantar hyperhidrosis. Done via retroperitoneal or laparoscopic approach - see the dedicated page.

  • Non-surgical alternatives to try first

    Aluminium chloride, iontophoresis, botox, miraDry (axilla only) and oral glycopyrrolate. Most patients should exhaust these before ETS.

Safety and recovery

What to expect afterwards - honestly.

ETS is technically well established. The things worth planning are the level, the technique, and how you will feel about compensatory sweating.

  • GA and single-lung ventilation

    Every case is under general anaesthetic with the anaesthetist collapsing one lung at a time. A thoracic-experienced anaesthetist is non-negotiable.

  • Compensatory sweating is the big one

    Up to 70 percent of patients notice new sweating on the back, chest, abdomen or thighs. In 5–10 percent it is severe enough to regret the operation. It is usually permanent.

  • Bleeding, pneumothorax, chylothorax

    Intraoperative bleeding, persistent air leak or chyle leak occur in under 1 percent of cases. Chest drains are used only when needed.

  • Horner syndrome

    Injury to the stellate ganglion causes a droopy eyelid, constricted pupil and reduced facial sweating on one side. Under 1 percent in experienced hands - but permanent when it happens.

  • Gustatory sweating

    A minority of patients develop sweating around the mouth when eating spicy or hot food. Usually mild.

  • Rebound and bradycardia

    A slower resting heart rate is common after R3/R4 procedures. Rarely enough to cause symptoms; occasionally noticeable in athletes.

  • Regret is real

    Around 2–5 percent of patients regret surgery, mostly because of compensatory sweating. Clipping offers a theoretical reversal window; division does not.

  • Recovery timeline

    Back to office work in 3–5 days, full activity by 2 weeks. Shoulder ache is normal for 48 hours. Palmar dryness is immediate.

  • Red flags after surgery

    Severe breathlessness, spreading redness, high fever or persistent chest pain need the same-day team or A&E, not a routine call.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever level was treated - R2, R3, R4 - the note the surgeon sends you keeps to the same shape.

A quiet reminder

Surgical language is precise and can read coldly - we translate it for you.

If you would like us to talk you through the operation note before your review, just ask.

    Indication and level treated

    Why the operation was done - palmar, axillary, facial - and at which sympathetic ganglion level (R2, R3, R4) each side was addressed.

  2. 02 Technique

    Approach and method

    Number of ports, clip versus division, whether nerves of Kuntz were divided. Any technical issues encountered on either side.

  3. 03 Findings

    Intraoperative findings

    Pleural adhesions, anatomical variation, tumours or unusual chain anatomy. Rare but recorded here.

  4. 04 Impression

    Post-op plan and follow-up

    Read this first: recovery expectations, when to review, and how compensatory sweating will be assessed and logged.

Frequently asked

Everything we get asked about ETS.

Quick answers on compensatory sweating, levels, non-surgical options, cost and recovery.

  • What is thoracic sympathectomy (ETS)?

    Endoscopic thoracic sympathectomy is a keyhole chest operation to interrupt the sympathetic nerve chain that drives sweating in the hands, armpits or face. It is performed bilaterally through two small ports on each side under general anaesthetic and takes about an hour.

  • Will I definitely get compensatory sweating?

    Most patients - around 70 percent - notice some new sweating on the back, chest, abdomen or thighs. In 5–10 percent it is severe enough to cause regret. Choosing R4 rather than R3 lowers the risk, and clipping preserves a theoretical route back, but no surgeon can promise you will avoid it.

  • Should I try iontophoresis, botox or miraDry first?

    Yes for most people. UK dermatology and NICE guidance suggests exhausting aluminium chloride, iontophoresis and - for axillary sweating - botox or miraDry before ETS.

  • Is ETS reversible?

    Clipping is theoretically reversible if clips are removed within 6–12 months, but reversal is not guaranteed and outcomes are unpredictable. Division or cautery is permanent. This is why the two-week cool-down before surgery matters.

  • How much does private ETS cost in the UK?

    Roughly £7,500–£11,500 for bilateral clipping, £7,000–£10,500 for division, and £5,000–£7,500 for a unilateral procedure. Consultation only is £300–£500.

  • How long is recovery?

    Most people are home the same day or after one night. Shoulder ache and mild breathlessness settle over 48 hours. Back to office work in 3–5 days, full activity by 2 weeks. Palmar dryness is usually immediate on the operating table.
