Thyroid Surgery

At Sydney Surgical Associates, we provide expert surgical care for a range of thyroid conditions.

The thyroid is a butterfly-shaped gland located in the lower part of the neck, playing a vital role in regulating the body’s metabolism through the release of thyroid hormones.

When the thyroid becomes overactive, underactive, enlarged, or develops nodules or cancer, surgical treatment may be recommended as part of a comprehensive care plan. Our experienced team of general and endocrine surgeons work closely with endocrinologists, radiologists, and pathologists to ensure each patient receives safe, effective, and individualised care.

Common Thyroid Conditions Requiring Surgery

Thyroid nodules are solid or fluid-filled lumps that form within the thyroid gland. Most nodules are benign and cause no symptoms, but a small percentage can be cancerous.

Causes:

  • Overgrowth of normal thyroid tissue
  • Thyroid cysts
  • Chronic inflammation (e.g., Hashimoto’s thyroiditis)
  • Multinodular goitre
  • Thyroid cancer


Symptoms:

  • A noticeable lump in the neck
  • Difficulty swallowing or breathing (in larger nodules)
  • Hoarseness
  • No symptoms in many cases


Diagnosis and Treatment:

Ultrasound and fine needle aspiration (FNA) biopsy help determine whether a nodule is benign or malignant. Surgery may be required if a nodule is suspicious, causing symptoms, or growing rapidly.

A goitre is an abnormal enlargement of the thyroid gland. It may be diffuse or multinodular and can be associated with normal, overactive (hyperthyroidism), or underactive (hypothyroidism) thyroid function.

Causes:

  • Iodine deficiency (historically common in Australia, though now rare due to iodine fortification)
  • Graves’ disease
  • Hashimoto’s thyroiditis
  • Multinodular goitre


Symptoms:

  • Visible swelling at the base of the neck
  • Tightness or discomfort in the throat
  • Difficulty swallowing or breathing (if the goitre presses on the windpipe or oesophagus)


Treatment Options:

Mild cases may be monitored or treated with thyroid hormone medication. Large or symptomatic goitres may require thyroidectomy, particularly if they compress nearby structures or extend into the chest (retrosternal goitre).

Hyperthyroidism occurs when the thyroid produces too much hormone, speeding up the body’s metabolism. It can be caused by several conditions, including:

  • Graves’ disease: an autoimmune condition causing diffuse overactivity of the thyroid
  • Toxic multinodular goitre: nodules that independently produce excess hormone
  • Thyroid adenoma: a benign tumour that secretes hormone


Symptoms:

  • Unintentional weight loss
  • Palpitations or irregular heartbeat
  • Anxiety or irritability
  • Tremors
  • Sweating or heat intolerance
  • Sleep disturbances
  • Menstrual irregularities


Treatment Options:

Initial management usually includes antithyroid medication or radioactive iodine therapy. Surgery (usually a total or subtotal thyroidectomy) may be recommended for:

  • Patients who do not respond to medical treatment
  • Women who are pregnant or planning pregnancy
  • Large goitres or co-existing nodules
  • Patient preference

Thyroid cancer is relatively uncommon in Australia but has seen rising incidence due to improved imaging and early detection. According to Cancer Australia, over 3,900 new cases of thyroid cancer are diagnosed each year, with a higher prevalence in women.

Types of Thyroid Cancer:

  • Papillary carcinoma (most common, slow-growing, excellent prognosis)
  • Follicular carcinoma
  • Medullary thyroid carcinoma
  • Anaplastic carcinoma (rare, aggressive)


Symptoms:

  • A painless lump or swelling in the neck
  • Hoarseness
  • Difficulty swallowing
  • Enlarged lymph nodes


Treatment Options:

Surgery is the first-line treatment and may involve:

  • Total thyroidectomy – removal of the entire thyroid
  • Hemithyroidectomy – removal of one lobe


This is often followed by radioactive iodine therapy, thyroid hormone replacement, and ongoing monitoring with blood tests and imaging.

Gastroscopy is typically performed as a day procedure under light sedation. A thin, flexible tube with a camera (endoscope) is passed through the mouth into the upper-GI tract. It allows your surgeon to inspect the lining of the oesophagus, stomach and duodenum, take biopsies, and treat certain issues on the spot (e.g., bleeding, removing polyps).

The procedure generally takes 10–15 minutes, and most patients recover quickly with minimal discomfort.

Thyroid surgery is generally safe but, like all procedures, carries some risks:

  • Bleeding or haematoma
  • Infection
  • Injury to the recurrent laryngeal nerve, which may cause hoarseness or voice changes
  • Low calcium levels (hypocalcaemia) due to inadvertent damage or removal of the parathyroid glands
  • Need for lifelong thyroid hormone replacement therapy (particularly after total thyroidectomy)

     

Most patients recover within 1-to-2 weeks, with minimal scarring, especially when modern minimally invasive techniques are used.

At Sydney Surgical Associates, our surgeons offer highly specialised care in thyroid surgery, including the management of complex and cancerous cases. We work closely with referring GPs and endocrinologists to deliver streamlined, coordinated care from diagnosis to recovery.

We prioritise surgical safety, optimal outcomes, and patient comfort. Our team is also experienced in nerve monitoring and minimally invasive techniques, helping reduce post-operative complications and improve recovery time.
