Thyroid Removal Surgery in Melbourne

Thyroidectomy is a surgical procedure to remove all or part of the thyroid gland, a butterfly-shaped gland at the front of the neck that regulates metabolism, energy, and several other body functions. It is performed to treat thyroid cancer, large or symptomatic thyroid nodules, goitre, and hyperthyroidism that have not responded to other treatments.

At Specialist Surgical Group, our Melbourne-based endocrine surgeons perform thyroidectomy using techniques designed to protect the structures that lie immediately adjacent to the thyroid: the recurrent laryngeal nerves, which control your vocal cords, and the parathyroid glands, which regulate calcium levels in the blood. Intraoperative nerve monitoring is used throughout the procedure to reduce the risk of voice changes.

Thyroidectomy may involve removing the entire gland (total thyroidectomy), one lobe (hemithyroidectomy), or a specific portion, depending on your diagnosis. The right extent of surgery is determined during your consultation and may be informed by biopsy pathology, imaging findings, and clinical factors.

Is thyroid removal surgery for you?

Thyroidectomy is a well-established treatment for a range of thyroid conditions. It may be appropriate for you if:

  • You have been diagnosed with thyroid cancer requiring surgical removal
  • You have large thyroid nodules causing compressive symptoms such as difficulty swallowing, breathing restriction, or voice changes
  • You have indeterminate or suspicious thyroid nodules that cannot be confidently diagnosed without a surgical specimen
  • You have hyperthyroidism, including Graves’ disease, that has not responded adequately to medication or radioactive iodine
  • You have a large goitre causing obstructive symptoms or cosmetic concerns
  • You have a family history of medullary thyroid cancer and carry a relevant genetic mutation, such as the RET proto-oncogene

During your initial consultation, your surgeon will review your symptoms, imaging studies, pathology results, and medical history to determine whether thyroidectomy is the most appropriate treatment for your specific situation.

Potential benefits

  • Effective treatment for thyroid cancer. For differentiated thyroid cancers, including papillary and follicular thyroid cancer, thyroidectomy provides definitive surgical treatment. The 5-year relative survival rate for localised differentiated thyroid cancer exceeds 99% [1][2].
  • Resolution of compressive symptoms. Patients with large goitres or symptomatic thyroid nodules typically experience significant relief from difficulty swallowing, breathing restriction, and voice changes following thyroid removal [3].
  • Definitive diagnosis for uncertain nodules. When fine-needle aspiration biopsy yields an indeterminate or suspicious result, surgical removal of the nodule provides a definitive pathological diagnosis, eliminating uncertainty and guiding long-term management [4].
  • Permanent control of hyperthyroidism. Total thyroidectomy provides immediate and definitive treatment for hyperthyroidism, including Graves’ disease, avoiding the relapse risk associated with antithyroid medications and the delayed effect of radioactive iodine [5].
  • Prevention of cancer spread. Surgical removal of thyroid cancer before it spreads to lymph nodes or distant organs significantly improves long-term prognosis and reduces the complexity of subsequent treatment [2].
  • Improved quality of life. A 2024 longitudinal study found meaningful, sustained improvements in quality of life following thyroidectomy in patients with differentiated thyroid cancer [6].
  • Established long-term safety. Thyroidectomy is one of the most thoroughly studied procedures in endocrine surgery, with well-characterised long-term outcomes when performed at high-volume centres by experienced surgeons [2].

Potential risks

  • Recurrent laryngeal nerve injury. The recurrent laryngeal nerves, which control the vocal cords, run immediately adjacent to the thyroid. Temporary hoarseness or voice change occurs in approximately 5-10% of patients; permanent significant vocal cord palsy is uncommon, occurring in less than 1-2% of cases when surgery is performed by experienced endocrine surgeons with intraoperative nerve monitoring [7].
  • Hypoparathyroidism (low calcium). The parathyroid glands lie close to or sometimes within the thyroid tissue and may be affected during surgery. Temporary low calcium (hypocalcaemia) occurs in approximately 20-30% of patients undergoing total thyroidectomy and is managed with calcium supplementation; permanent hypoparathyroidism requiring lifelong calcium and vitamin D supplementation occurs in approximately 1-3% of cases [8].
  • Post-operative bleeding. Significant haematoma requiring return to theatre occurs in approximately 1-2% of thyroidectomy cases. Neck haematoma can be serious due to the potential for airway compression, which is why all patients are monitored in hospital overnight [9].
  • Lifelong thyroid hormone replacement. Following total thyroidectomy, daily levothyroxine is required to replace the hormones the thyroid gland no longer produces. This is generally well tolerated, but requires regular blood tests and dose adjustments, particularly in the first 12 months after surgery [10].
  • Scar formation. A small, permanent scar in the natural neck crease is expected following thyroidectomy. Most scars fade considerably over 12-18 months. Remote-access surgical techniques may be considered for selected patients who prefer to avoid a visible neck scar [7].

Your thyroidectomy journey

The following steps provide a brief overview of your journey for thyroidectomy. Individual experiences will vary based on your specific health circumstances.

1. Initial consultation and health assessment

Your surgeon will review your symptoms, imaging, biopsy results, and thyroid function tests, and examine your neck.

The extent of surgery (hemithyroidectomy or total thyroidectomy) will be discussed, and any baseline voice or calcium assessments will be arranged if needed.

2. Pre-operative preparation

You will receive instructions covering fasting, medication management, and what to expect on the day.

Patients on antithyroid medications for Graves’ disease will be given specific guidance on adjusting these before surgery. Any outstanding specialist referrals will be coordinated at this stage.

3. The thyroidectomy procedure

Thyroidectomy is performed under general anaesthesia at an accredited Melbourne hospital and takes approximately 1-3 hours. A 3-5 cm incision is made in a natural neck crease. Using magnification and careful dissection, the thyroid is separated from surrounding structures.

Intraoperative nerve-monitoring probes are used throughout to protect the recurrent laryngeal nerves, and the parathyroid glands are identified and preserved when possible.

The gland is removed and sent to pathology. The wound is closed with dissolving sutures or surgical glue.

4. Hospital recovery

Most patients can speak and swallow comfortably. Calcium levels are checked by blood test within a few hours of surgery, and supplementation is commenced if needed.

Mild neck discomfort and difficulty swallowing during the first 24-48 hours are common and can be managed with simple analgesia. Most patients stay 1-2 nights.

Before discharge, your surgeon will review your surgical site, voice, and calcium levels, and provide wound care instructions and follow-up details.

5. Follow-up and monitoring

Your surgeon will see you 1-2 weeks after surgery to review your incision and pathology results. If you have had a total thyroidectomy, levothyroxine is typically commenced on discharge, with dose adjustments guided by blood tests at 6-8 weeks.

If cancer is confirmed, your care will be coordinated with an endocrinologist and, where indicated, radioactive iodine therapy. Most patients with differentiated thyroid cancer move to annual or biannual surveillance once stable.

Thyroidectomy surgery FAQ

How long will I need to take time off work after a thyroidectomy?

Most patients can return to desk-based work within 1-2 weeks of surgery. Those with physically demanding jobs or roles involving prolonged voice use may need 3-4 weeks off. We will provide a return-to-work recommendation based on your specific occupation and the progression of your recovery.

Will I have a visible scar on my neck?

A small scar in a natural skin crease at the front of the neck is expected following thyroidectomy. With appropriate wound care, most scars fade considerably over 12-18 months and become difficult to notice at a normal conversational distance. For selected patients who prefer to avoid a visible neck scar, remote-access techniques can be discussed at your consultation.

Will my voice be permanently affected?

The large majority of patients experience no permanent change to their voice. We use intraoperative nerve monitoring throughout thyroidectomy to identify and protect the recurrent laryngeal nerves. Temporary hoarseness or a mild change in voice quality occurs in some patients and typically resolves within a few weeks. Permanent significant voice change is uncommon when surgery is performed by an experienced endocrine surgeon.

What does thyroidectomy cost in Melbourne, and is it covered by Medicare or private health insurance?

The total cost of thyroidectomy varies depending on the extent of surgery, the hospital used, your anaesthetist, and your private health insurance policy.

For medically indicated thyroidectomy, Medicare provides a rebate on the surgeon’s fee under the relevant Medicare Benefits Schedule (MBS) item numbers. Most patients with hospital-level private health insurance will have the main hospital costs covered, subject to any excess and applicable waiting periods.

Out-of-pocket costs, which typically range from $1,500-$5,000 depending on your cover, will be discussed and itemised at your consultation. We encourage you to contact your insurer before booking.

When will I need to start thyroid hormone replacement?

If you have a total thyroidectomy, levothyroxine is typically commenced on the day of or the day after surgery. Blood tests are checked at 6-8 weeks to guide dose adjustments. If you have a hemithyroidectomy, thyroid hormone replacement may not be required if the remaining lobe produces adequate hormone, though this will be monitored with blood tests over the following months.

Can I drive myself home after the surgery?

No. You will need a responsible adult to drive you home and remain with you for the first 24 hours after surgery. General anaesthesia affects reaction time and judgment, making driving unsafe for at least 24 hours. As a general guide, you should not drive until you are no longer taking prescription pain medication and can comfortably perform an emergency stop.

What if my pathology results show cancer?

If thyroid cancer is confirmed, your surgeon will discuss the findings with you in detail at your follow-up appointment. Depending on the type, stage, and features of the cancer, additional treatment such as radioactive iodine therapy may be recommended. Your care will be coordinated with an endocrinologist and, where appropriate, an oncologist. The vast majority of differentiated thyroid cancers (papillary and follicular) have excellent long-term outcomes when appropriately treated.

Will I gain weight after thyroidectomy?

With properly managed thyroid hormone replacement, your metabolism should remain stable, and weight gain should not occur as a direct result of the operation. In the weeks before a stable levothyroxine dose is established, some patients notice mild changes in energy or weight. We closely monitor thyroid hormone levels during the first 6-12 months and adjust your medication as needed to maintain optimal metabolic function.

How does thyroidectomy compare to other treatments for hyperthyroidism?

For hyperthyroidism, the main alternatives to thyroidectomy are antithyroid medications (such as carbimazole) and radioactive iodine. Antithyroid medications must be taken long-term and carry a significant relapse rate after cessation. Radioactive iodine is effective but takes several months to work, cannot be used in pregnancy, and may still result in eventual hypothyroidism. Total thyroidectomy provides immediate and permanent resolution of hyperthyroidism and is generally preferred when the goitre is large, malignancy is suspected, or when rapid control is needed.

How does thyroid surgery relate to parathyroid gland surgery or adrenal gland surgery?

These are three distinct endocrine surgery procedures addressing different glands. Parathyroid gland surgery (parathyroidectomy) treats overactive parathyroid glands that cause elevated blood calcium levels.

Adrenal gland surgery (adrenalectomy) addresses hormone-producing adrenal tumours. All three procedures are performed by our endocrine surgery team and can be discussed in the same consultation if you have concerns about more than one gland.
