The operation, step-by-step · UK

Thyroidectomy - technique, monitored honestly.

The technical guide to removing part or all of the thyroid gland - with continuous nerve monitoring, parathyroid preservation and a structured recovery pathway.

  • 01

    Nerve monitoring on every case

    Continuous intraoperative recurrent laryngeal nerve monitoring is our default, not an upgrade. Superior laryngeal branch is mapped too where the anatomy demands it.

  • 02

    Parathyroids identified and preserved

    Every parathyroid gland is identified and photographed in the operative record. Autotransplantation is used when a gland cannot be preserved.

  • 03

    Day-case ready where appropriate

    Enhanced-recovery lobectomy on a day-case pathway, and one-night stays for most totals - with same-day PTH and calcium built in.

Indications

When thyroidectomy is the operation of choice.

Malignancy, uncontrolled hyperthyroidism, compressive goitre, retrosternal extension and RET prophylaxis.

  • Malignant (Thy 5) cytology

    A definite cancer diagnosis on FNA - needs hemi- or total thyroidectomy depending on stage.

  • Suspicious (Thy 4) cytology

    A strong suspicion of cancer - usually managed with hemithyroidectomy as a diagnostic and therapeutic step.

  • Indeterminate (Thy 3) cytology after MDT

    Cytology that cannot commit - where imaging, molecular testing and clinical picture push toward hemithyroidectomy.

  • Symptomatic multinodular goitre

    Compressive symptoms - dysphagia, positional dyspnoea, cosmetic concern - with a large or retrosternal gland.

  • Graves or toxic multinodular disease

    Uncontrolled hyperthyroidism, active eye disease, planned pregnancy, or where radioiodine is unsuitable.

  • Retrosternal extension

    A goitre reaching below the sternum on CT - usually requires total thyroidectomy, sometimes with sternal split.

  • Prophylactic thyroidectomy

    RET mutation carriers (MEN 2A/B, FMTC) - timing driven by mutation and calcitonin, done before medullary cancer develops.

  • Red flag: fixed lump with hoarseness

    A hard fixed neck lump with new voice change points to locally advanced cancer - urgent two-week-wait head-and-neck oncology, not routine private list.

Variants

Every extent of thyroidectomy we perform.

From isthmusectomy to lateral neck dissection and retrosternal cases with sternotomy.

  • Hemithyroidectomy (lobectomy)

    Removal of one lobe and isthmus. Preserves contralateral hormone production in most people. Day-case pathway suitable in low-risk anatomy.

  • Isthmusectomy

    Removal of the isthmus alone. A narrow indication - a single central isthmic nodule with a small volume of surrounding parenchyma.

  • Total thyroidectomy

    Removal of the entire gland. The standard for bilateral disease, Graves, larger cancers and retrosternal extension.

  • Completion thyroidectomy

    A second operation to remove the remaining lobe after diagnostic hemithyroidectomy - usually because histology upstaged the disease.

  • Central compartment (Level VI) dissection

    Removal of paratracheal and pretracheal nodes for proven or suspected cancer with nodal involvement.

  • Lateral neck dissection (Levels II–V)

    Selective neck dissection for lateral nodal metastases, usually planned pre-operatively on ultrasound and FNA.

  • Retrosternal / substernal approach

    A conventional collar incision handles most retrosternal goitres. A partial or full sternotomy is rarely required - always planned in advance.

  • Robotic and transoral thyroidectomy

    Available in selected UK units for cosmetically motivated cases. Longer operating time, no visible neck scar - patient selection matters.

Our operative standards

Non-negotiables in every case.

A short list of things every unit in our network commits to for thyroidectomy.

  • BAETS-registered consultants performing 50+ thyroid cases a year

  • Nerve-integrity monitor tubes and continuous IONM on every case

  • Parathyroid autotransplantation available and used when indicated

  • Same-day PTH assay and structured calcium replacement protocol

Complications

The specific technical risks, quantified.

Recurrent laryngeal, superior laryngeal, parathyroids, haematoma, chyle leak - each considered.

  • Recurrent laryngeal nerve

    Runs in the tracheo-oesophageal groove. Continuous IONM reduces - but does not eliminate - the risk. Permanent injury under 1 percent in high-volume series.

  • External branch of the superior laryngeal nerve

    Supplies the cricothyroid muscle and pitch control. Injury blunts high notes and projection - a specific issue for singers and teachers.

  • Parathyroid injury and hypocalcaemia

    Transient hypocalcaemia in up to 20 percent of totals; permanent in 1–3 percent. Same-day PTH stratifies who needs supplements.

  • Neck haematoma

    Under 1 percent but time-critical - a bulging, tight wound after surgery needs immediate opening. Every ward has a bedside emergency kit.

  • Seroma and wound issues

    Small seromas may need aspiration. Infection under 1 percent with modern skin closure.

  • Chyle leak

    Rare, after lateral neck dissection on the left. Managed with low-fat diet, occasionally somatostatin or return to theatre.

  • Pneumothorax and tracheal injury

    Very rare complications of retrosternal or extensive dissections - managed intraoperatively.

  • Levothyroxine dose settling

    Starting dose about 1.6 mcg/kg after total thyroidectomy. TSH-guided titration over 3–6 months.

  • Red flags after discharge

    Tight or bulging neck wound, difficulty breathing, sudden voice loss, tingling around mouth or hands - call the same-day team or A&E.

Frequently asked

Technical answers about the operation.

  • What exactly is a thyroidectomy?

    A surgical operation that removes part or all of the thyroid gland through a small transverse incision in the lower neck. It is performed under general anaesthetic in about 60–180 minutes depending on extent, with continuous nerve monitoring and same-day parathyroid function checks.

  • How is a total thyroidectomy done step-by-step?

    A collar incision is made in a skin crease, subplatysmal flaps are raised, the strap muscles are separated in the midline, each lobe is mobilised on its capsule using energy devices, the recurrent laryngeal nerve is identified and monitored throughout, parathyroid glands are preserved on their vascular pedicles, and the gland is removed en bloc. Haemostasis is checked, and the wound is closed in layers with a fine dermal suture.

  • How long does the operation take?

    Hemithyroidectomy typically takes 60–90 minutes; total thyroidectomy 90–150 minutes; with central compartment dissection 120–180 minutes; and lateral neck dissection can extend to 240 minutes. Retrosternal or reoperative cases add time.

  • Will I go home the same day?

    Yes for many hemithyroidectomies on our enhanced-recovery pathway. Total thyroidectomies stay one night for a same-day PTH and morning calcium. Nodal dissections and retrosternal cases stay 2–3 nights.

  • How much does a private thyroidectomy cost in the UK?

    Roughly £7,500–£11,000 for a hemithyroidectomy, £9,500–£14,000 for a total thyroidectomy, £12,000–£18,000 with central compartment dissection, and £15,000–£23,000 with lateral neck dissection. We confirm firm figures across two or three consultants within one working day.

  • What are the specific technical risks of the operation?

    The main technical risks are injury to the recurrent laryngeal nerve (permanent under 1 percent), the external branch of the superior laryngeal nerve, parathyroid gland injury with resulting temporary or permanent hypocalcaemia, neck haematoma, and - for lateral dissections - chyle leak. Each is minimised by high-volume surgery, IONM and careful capsular technique.
