Ptosis surgery - the anatomy, and the right technique for it.

A practical UK guide to how oculoplastic surgeons choose between external levator resection, posterior Müller’s muscle-conjunctival resection and frontalis suspension - driven by levator function, phenylephrine response and the underlying cause of the droop.

The NHS operates ptosis where the visual axis is measurably obstructed - typically an MRD1 of 2 mm or less with a documented visual-field defect. Waits for functional cases are commonly nine to eighteen months. Purely cosmetic droop is not funded on the NHS and is treated privately.

The problem

One name, several diseases, and three different operations.

Ptosis is a symptom, not a diagnosis. The right operation depends on which anatomical element has failed - tendon, muscle, nerve or a mechanical load - and on how much lifting the remaining muscle can still do.

  • Diagnose the cause first

    Aponeurotic, myogenic, neurogenic, mechanical, traumatic, congenital or pseudoptosis - each has a different natural history and a different theatre plan.

  • Measure levator function

    The excursion of the upper lid from down-gaze to up-gaze, brow held still. This one number selects between anterior, posterior and sling techniques.

  • Test Müller’s with phenylephrine

    A drop of 2.5% phenylephrine tells you whether a small posterior resection will work. It is the cheapest and most useful office test in oculoplastics.

Classification

The seven types of ptosis - and one imposter.

The classical Frueh classification steers technique choice and warns about the presentations that need neurology, not theatre.

  • Aponeurotic (involutional)

    A stretched or disinserted levator aponeurosis with preserved muscle. Levator function is normal, crease sits high. Fixed by reattaching the tendon anteriorly.

  • Myogenic

    The levator muscle itself is weak - chronic progressive external ophthalmoplegia, oculopharyngeal dystrophy, myotonic dystrophy. Levator function is poor; a sling is usually the honest option.

  • Neurogenic

    Third-nerve palsy, Horner syndrome, Marcus Gunn jaw-winking. Anatomy is intact but innervation is not. Surgery only after the underlying cause is stable, and never before neurology has cleared it.

  • Mechanical

    A lid weighed down by a chalazion, tumour, oedema or scar contracture. Address the mechanical load first - sometimes no muscle surgery is needed.

  • Traumatic

    Levator laceration or disinsertion after eyelid trauma. Best repaired within 6 months; delayed cases behave like aponeurotic ptosis with scarring.

  • Congenital dystrophic

    Fatty and fibrotic levator with poor excursion and absent upper-lid crease. Frontalis suspension for severe cases; large levator resection for moderate ones.

  • Pseudoptosis

    A lid that looks low without true ptosis - dermatochalasis, brow ptosis, contralateral lid retraction, enophthalmos, hemifacial atrophy. Surgery on the wrong tissue leaves the problem intact.

  • Red flag: variability and diplopia

    A droop that changes through the day, with double vision or fatigable weakness on sustained up-gaze, is myasthenia gravis until proven otherwise. Bloods, ice-pack test and neurology before any theatre.

Techniques

Every technique, and the anatomy it addresses.

From a calibrated internal 6.5 mm resection to a maximal Whitnall’s sling, each operation targets a different failing element in the eyelid.

  • External (anterior) levator resection

    Through the skin crease. The aponeurosis is exposed, shortened by a measured length and re-anchored to the upper third of the tarsus. Suits levator function ≥ 4 mm; the workhorse for moderate ptosis.

  • Levator aponeurosis advancement

    A smaller anterior procedure. The dehisced aponeurosis is re-anchored without shortening much muscle. Ideal for classical aponeurotic ptosis with strong levator function.

  • Müller’s muscle-conjunctival resection (Putterman)

    A calibrated internal resection - 6.5, 8.5 or 9.5 mm - through the lid’s inner surface. Requires a positive phenylephrine test and levator function ≥ 10 mm. No skin scar.

  • Fasanella–Servat tarso-conjunctival resection

    A small tarsus, conjunctiva and Müller’s wedge for mild ptosis with good levator function. Simple, predictable, but sacrifices tarsus, so avoided when heavy adjustment is needed.

  • Frontalis suspension (sling)

    A silicone rod, Gore-Tex or a strip of the patient’s fascia lata connects tarsus to the frontalis muscle. First choice when levator function is < 4 mm - the forehead does the lifting.

  • Whitnall’s sling with maximal levator resection

    Whitnall’s ligament is used as a fulcrum after a large levator shortening. A middle-ground option in moderate congenital ptosis where a sling feels like over-treatment.

  • Berke and modified Berke techniques

    Large-volume anterior levator resections for severe congenital ptosis with fair function. Preserves natural lid movement more than a sling but demands accurate function measurement.

  • Autogenous fascia lata versus banked material

    Autogenous fascia lata gives the most durable sling - five-year re-operation rates around 10 percent - at the cost of a thigh incision. Silicone rods are adjustable and reversible but stretch over time.

Safety and recovery

The specific risks of the technique you are having.

Some risks - under-correction, contour, Hering - are shared. Others are specific to anterior, posterior or sling work and are easier to plan around when named up front.

  • Local anaesthetic is preferred for adults

    Sitting-up adjustment during external procedures needs the patient awake and cooperative. General anaesthetic is reserved for children, sling surgery on adults who cannot tolerate awake work, and long combined cases.

  • Under-correction - the commonest problem

    Reported at 8–14 percent across published series, most in the first six weeks before final settling. A targeted early revision at three months is preferable to a large one at six.

  • Over-correction and lagophthalmos

    An over-lifted lid does not close fully at night. Managed conservatively with lubricants and lid taping for the first month; persistent cases need a small posterior release.

  • Contour abnormalities

    Peaked, flat or notched lid contours reflect uneven tarsal fixation. Anterior techniques let the surgeon see and adjust the contour on the table; posterior techniques rely on symmetrical calibrated resection.

  • Corneal exposure and dry eye

    A weak Bell’s phenomenon on pre-op examination is a warning - plan a smaller lift and pre-treat the tear film. Preservative-free tears and night ointment for six weeks post-op.

  • Hering’s law - the contralateral lid

    Lifting one lid can drop the fellow lid through equal neural drive. A phenylephrine or manual elevation test before surgery predicts this; sometimes bilateral surgery is the honest answer.

  • Suture granuloma, cyst, notch

    Small local reactions in the first three months. Warm compresses and short topical steroids resolve most; a persistent granuloma needs a small clinic excision.

  • Vision-threatening complications are very rare

    Retrobulbar haemorrhage, orbital cellulitis and optic-nerve compromise are reported at less than 1 in 10,000. Sudden proptosis, severe pain or vision loss needs the on-call team immediately.

  • Amblyopia risk in children

    Congenital ptosis covering the visual axis before age 8 can cause deprivation amblyopia. Sling surgery is sometimes done early to preserve visual development, then revised at adolescence.

Reading your operation note

Your operation note in four parts. The numbers matter.

Whichever technique was used, the note the surgeon sends you follows the same structure - and the millimetre figures are the paragraph a revision surgeon would read first.

Frequently asked

Everything we get asked about ptosis surgery.

Quick answers on technique choice, sling materials, phenylephrine testing, cost and recovery.

  • How do surgeons choose between levator, Müller’s and a sling?

    The single most useful number is levator function - the excursion of the upper lid from down-gaze to up-gaze with the brow held still. Good function (≥ 10 mm) with a positive phenylephrine test suggests a posterior Müller’s muscle-conjunctival resection. Function of 4–10 mm points to an external levator advancement or resection. Function below 4 mm - as in most congenital dystrophic and myogenic ptosis - is best treated with a frontalis suspension, because the muscle simply cannot do the work.

  • Will the NHS or my insurer pay for ptosis surgery?

    The NHS funds ptosis surgery where the visual axis is measurably obstructed - commonly an MRD1 of 2 mm or less with a Humphrey visual-field defect of 30 percent or more superiorly. Purely cosmetic droop is not funded on the NHS; waits for functional cases are commonly nine to eighteen months. Private medical insurers apply the same functional test and generally cover levator, Müller’s and sling procedures on the same evidence.

  • What is a frontalis sling actually made of?

    The two mainstream choices in the UK are a silicone rod (a preformed elastic strap with adjustable Watzke sleeves) and autogenous fascia lata (a strip taken from the patient’s own thigh). Silicone is quicker and reversible but slowly stretches over five to ten years. Fascia lata gives the most durable correction - five-year re-operation rates around 10 percent - at the cost of a small thigh scar. Banked cadaveric fascia and Gore-Tex sit in between.

  • What does phenylephrine testing tell the surgeon?

    Phenylephrine 2.5% drops stimulate Müller’s muscle. If the lid lifts 2 mm or more within ten minutes, the Müller’s muscle has enough contractile tissue to make a posterior conjunctival-Müller’s resection reliable. A negative test does not rule out surgery, but it steers the plan toward an anterior levator technique instead.

  • How much does private ptosis surgery cost in the UK in 2026?

    Roughly £3,500–£5,000 for a posterior Müller’s procedure, £4,000–£6,500 for a unilateral external levator, and £5,500–£9,000 bilateral. A silicone frontalis sling is £4,500–£7,000; autogenous fascia lata £6,000–£8,500. All-in fees generally include the consultation, surgery, up to three months of reviews and - with reputable UK oculoplastic surgeons - a defined revision policy.

  • How long is the surgery and how long is the recovery?

    Posterior Müller’s: 30–45 minutes with almost no bruising, back to work at day 3–5. External levator: 45–90 minutes with a fine skin-crease scar and 1–2 weeks of purple; sutures out day 5–7, back to office work by day 7–10. Frontalis sling: 60–120 minutes with tighter closure for four to six weeks and steady final settling over three months.
