The problem

The right team, the right route, the right hormone plan.

Pituitary adenomas are surprisingly common and quietly complex. Outcomes hinge on three things - a dedicated MDT, endoscopic experience by the hundreds, and a hormone plan that runs from day one, not day thirty.

  • MDT case selection

    A pituitary MDT decides whether to operate, watch or trial medical therapy - the single biggest determinant of outcome.

  • Endoscopic volume

    Complication rates fall sharply above 50 endoscopic cases a year. We only use centres above that threshold.

  • Endocrine follow-up

    Cortisol, sodium and pituitary axis testing on a scheduled protocol - not left to your GP to chase.

When it helps

When pituitary surgery is the right step.

The situations we see most, plus the red flag that means neurosurgery today, not next week.

  • Non-functioning macroadenoma pressing the chiasm

    A tumour larger than 10 mm compressing the optic chiasm - classic bitemporal hemianopia on visual fields. Surgery is the standard first step.

  • Cushing’s disease

    An ACTH-secreting adenoma driving cortisol excess. Endoscopic transsphenoidal resection is first-line, with remission rates of 70–90% in expert centres.

  • Acromegaly

    A growth hormone-secreting adenoma. Surgery is first-line for almost all cases; medical therapy (somatostatin analogues) covers residual disease.

  • Prolactinoma failing or intolerant of cabergoline

    Most prolactinomas shrink on cabergoline. Surgery is reserved for drug intolerance, resistance, cyst formation or pregnancy planning with a large tumour.

  • Pituitary apoplexy

    Sudden haemorrhage or infarction into an adenoma - thunderclap headache, visual loss, ophthalmoplegia. Urgent surgery if vision is threatened.

  • Rathke’s cleft cyst or symptomatic craniopharyngioma

    Sellar and suprasellar lesions that mimic adenomas but need drainage or resection when they cause visual or endocrine problems.

  • TSH-secreting adenoma

    A rare cause of central hyperthyroidism. Endoscopic resection is first-line after medical stabilisation.

  • Red flag: sudden visual loss with headache

    Sudden loss of vision, double vision or a violent headache in a known adenoma is apoplexy. A&E and neurosurgery the same day, not a routine referral.

Procedure options

Route and extent depend on the tumour, not the surgeon’s habits.

What each option involves - endoscopic transsphenoidal, extended endoscopic, transcranial, and where radiosurgery or medical therapy earn their place.

  • Endoscopic endonasal transsphenoidal

    The default. A high-definition endoscope through one nostril, through the sphenoid sinus, into the sella. Panoramic view, no head incision, day three to five discharge.

  • Microscopic transsphenoidal

    The older microscope-based technique. Still valid in some centres, but the endoscopic view has become standard for most adenomas.

  • Extended endoscopic approach

    For giant tumours, suprasellar extension or invasion of the cavernous sinus. Higher CSF leak risk, so a formal skull-base repair is planned from the outset.

  • Transcranial (craniotomy) approach

    Reserved for a small share of tumours - giant, dumbbell-shaped, or with extensive lateral or anterior extension the nose route cannot safely reach.

  • Debulking versus complete resection

    For functioning tumours we aim for complete resection to normalise hormones. For large non-functioning adenomas, safe decompression of the chiasm often matters more than clearing the last fragment.

  • Stereotactic radiosurgery adjunct

    Gamma Knife or CyberKnife for a residual or recurrent tumour where more surgery is high-risk. Hormone normalisation takes months to years.

  • Medical therapy first for prolactinomas

    Cabergoline shrinks most prolactinomas and normalises prolactin. Surgery is a second-line, not first-line, choice for these.

  • Watch and rescan

    A small, non-functioning incidentaloma that does not touch the chiasm and behaves normally on bloods often deserves observation, not the theatre list.

Safety and recovery

What to expect afterwards - honestly.

Endoscopic transsphenoidal surgery is one of the great modern neurosurgical stories, but three things - CSF leak, sodium and cortisol - need careful hands.

  • General anaesthetic in a neurosurgical theatre

    A neuro-anaesthetist runs the case, image guidance is on the screen, and a dedicated pituitary nurse specialist meets you before and after.

  • CSF leak - the main technical risk

    Endoscopic transsphenoidal carries a 2–5% CSF leak rate, higher in extended approaches. A multi-layer skull-base repair, sometimes with a nasoseptal flap, is standard.

  • Diabetes insipidus - usually transient

    Up to a third of patients pass large volumes of dilute urine in the first days. Permanent diabetes insipidus needing desmopressin affects around 2–5% of cases.

  • New anterior pituitary deficiency

    A new cortisol, thyroid, growth hormone or gonadotropin deficit affects 5–20% of macroadenoma cases. We test formally at six weeks and replace what is missing.

  • Sinonasal symptoms

    Nasal crusting, altered smell and a blocked feeling for six to twelve weeks are common. Saline irrigation from day seven speeds it up.

  • Rare vascular and neurological risks

    Carotid injury, cranial nerve palsy and meningitis each affect well under 1% of cases in experienced centres - but they are the events consent must cover honestly.

  • Visual outcomes

    When surgery is done for chiasmal compression, vision improves in about 80% of patients. Recovery starts within days and continues for six to twelve months.

  • Steroid cover and the day-eight cortisol

    Hydrocortisone is given peri-operatively and stopped only when a fasting 9 am cortisol on day eight confirms the axis is intact. Never stop steroids on your own.

  • Red flags after discharge

    Clear watery nose discharge, thunderclap headache, fever with neck stiffness, severe thirst with huge urine output, or worsening vision - same-day contact with the on-call neurosurgery team.

Reading your operation note

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

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 and the histology before your review, just ask.

  1. 01 Header

    Tumour type, size and approach

    Functioning or non-functioning, microadenoma or macroadenoma, and whether the route was endoscopic transsphenoidal, extended or transcranial.

  2. 02 Technique

    Findings and extent of resection

    What the surgeon saw at the sella, whether the chiasm decompressed, whether the cavernous sinus was involved, and gross-total, near-total or subtotal resection.

  3. 03 Findings

    Histology and immunostaining

    The pathology on the tumour - lineage, Ki-67 proliferation index, and hormone immunostain profile. Ki-67 above 3% earns closer follow-up.

  4. 04 Impression

    Hormone plan and follow-up

    Read this first: what to replace now (hydrocortisone, desmopressin, thyroxine), what will be re-tested at six weeks, and the schedule of MRIs.

Frequently asked

Everything we get asked about pituitary surgery.

Quick answers on the endoscopic route, hospital stay, hormone replacement, cost and remission rates.

  • Do you always have to go through the nose?

    For the great majority of pituitary tumours, yes - the endoscopic endonasal transsphenoidal route reaches the sella without opening the skull or retracting brain. A transcranial approach is reserved for the small share of tumours with giant size, dumbbell shape or extensive lateral extension that the nose route cannot safely reach.

  • How long is the hospital stay after transsphenoidal surgery?

    Three to five nights is typical for a straightforward case. You come back to a neuro-observation bay overnight for sodium and fluid balance monitoring, nasal packing comes out at 24–48 hours, and hydrocortisone continues until the day-eight cortisol result confirms the adrenal axis is intact.

  • Will I need hormone tablets for life afterwards?

    Not always. Many patients - especially with small non-functioning adenomas - leave with normal pituitary function. Larger tumours, apoplexy and re-do surgery raise the chance of needing hydrocortisone, thyroxine, desmopressin or sex hormone replacement. We test formally at six weeks and replace only what is truly missing.

  • What is diabetes insipidus and will I get it?

    It is a temporary or permanent loss of the antidiuretic hormone that lets the kidneys concentrate urine - you pass large volumes of dilute urine and become very thirsty. Transient diabetes insipidus is common in the first few days after surgery; the permanent form affects around 2–5% of patients and is easily controlled with desmopressin.

  • How much does private pituitary surgery cost in the UK?

    Roughly £22,000–£32,000 for endoscopic transsphenoidal microadenoma resection, £28,000–£40,000 for a macroadenoma, and £38,000–£55,000 for an extended endoscopic case. Transcranial surgery is £40,000–£65,000. Prices include the pituitary MDT, imaging, theatre, ward stay and initial endocrine follow-up.

  • What is the cure rate for Cushing’s disease and acromegaly?

    In dedicated pituitary centres, endoscopic transsphenoidal surgery brings biochemical remission in 70–90% of Cushing’s cases and 60–80% of acromegaly cases, depending on tumour size and cavernous sinus invasion. Residual disease is treated with medical therapy, repeat surgery or stereotactic radiosurgery.
