Thyroid Surgery in Thailand

Thyroid surgery may be considered when thyroid nodules, enlargement, overactivity or suspected thyroid cancer require surgical treatment.

Depending on the condition, the surgeon may remove one part of the thyroid gland or the entire gland.

Thailand offers specialist thyroid and endocrine surgeons, advanced diagnostic imaging and modern private surgical facilities for international patients considering planned thyroid surgery.

Siam Medica can help you explore suitable providers, share medical records for specialist review, request personalised treatment plans and cost estimates, and coordinate care before, during and after treatment in Thailand.

What is the thyroid gland?

The thyroid is a small butterfly-shaped gland located at the front of the neck.

It produces hormones that help regulate:

• Metabolism

• Heart rate

• Body temperature

• Energy use

Thyroid conditions are common and many can be managed without surgery.

Surgery is considered when the nature, size or behaviour of the thyroid condition makes removal appropriate.

When may thyroid surgery be considered?

Surgery may be recommended for:

• Thyroid cancer

• Nodules suspicious for cancer

• Large thyroid nodules

• Enlarged thyroid causing pressure symptoms

• Difficulty swallowing or breathing caused by thyroid enlargement

• Certain cases of hyperthyroidism

• Multinodular goitre

• Other thyroid conditions that do not respond appropriately to non-surgical treatment

The reason for surgery influences how much of the thyroid needs to be removed.

Thyroid lobectomy

A thyroid lobectomy removes one lobe of the thyroid gland.

It may be considered when a suspicious or problematic nodule is confined to one side.

The remaining thyroid tissue may continue producing sufficient thyroid hormone.

Some patients therefore do not require long-term thyroid-hormone replacement after lobectomy.

Blood tests are used after surgery to monitor thyroid function.

Total thyroidectomy

A total thyroidectomy removes essentially all of the thyroid gland.

It may be recommended for:

• Certain thyroid cancers

• Large multinodular goitres

• Disease affecting both thyroid lobes

• Selected cases of hyperthyroidism

• Other conditions requiring complete removal

Patients who undergo total thyroidectomy require lifelong thyroid-hormone replacement medication.

Minimally invasive and alternative approaches

Conventional thyroid surgery usually uses a small incision at the lower front of the neck.

Some centres also offer endoscopic, robotic or transoral approaches in selected patients.

A transoral approach accesses the thyroid through incisions inside the mouth and can avoid a visible neck scar.

These techniques are not appropriate for every thyroid condition.

The choice should prioritise safe treatment of the thyroid disease rather than scar avoidance alone.

Assessment and diagnosis

Before thyroid surgery, evaluation may include:

• Thyroid ultrasound

• Thyroid-function blood tests

• Fine-needle aspiration biopsy

• CT or other imaging where appropriate

• Examination of the neck

• Assessment of vocal-cord function

• Review of previous pathology or biopsy results

If thyroid cancer is suspected, the surgeon may also evaluate lymph nodes in the neck.

International patients can often send ultrasound images, biopsy results and laboratory reports before travelling for specialist review.

Fine-needle aspiration biopsy

Many thyroid nodules can be evaluated using a fine-needle aspiration biopsy.

A thin needle is used to collect cells from the nodule for laboratory analysis.

The result can help determine whether surgery is necessary.

Some biopsy findings remain uncertain, and surgery may occasionally be recommended to obtain a definitive diagnosis.

Preparing for surgery

Before surgery, patients generally undergo medical and anaesthetic assessment.

The medical team reviews:

• Thyroid function

• Current medication

• Blood-thinning medication

• Other medical conditions

• Previous neck surgery

• Voice symptoms

• Calcium and other blood-test results

Patients with an overactive thyroid may need medication to stabilise thyroid function before surgery.

The procedure

Thyroid surgery is normally performed under general anaesthesia.

The surgeon carefully separates the thyroid from surrounding structures and removes the planned amount of tissue.

Important nearby structures include:

• Nerves controlling the vocal cords

• Parathyroid glands controlling calcium levels

• Major blood vessels

• The airway

Protecting these structures is an important part of thyroid surgery.

Hospital stay and recovery

Hospital stay depends on the extent and surgical approach.

A thyroid lobectomy may involve around two nights in hospital.

Total thyroidectomy may require approximately three nights depending on the patient and provider.

After surgery, patients may experience:

• Neck soreness

• Tightness

• Temporary swallowing discomfort

• Mild voice changes

Most patients begin walking and eating relatively soon after surgery.

Voice changes after thyroid surgery

Temporary hoarseness can occur after thyroid surgery.

This may result from irritation related to the breathing tube or temporary irritation of nerves around the thyroid.

Permanent vocal-cord weakness from nerve injury is an important but less common complication.

Patients with persistent voice changes should be evaluated appropriately after surgery.

Calcium levels after total thyroidectomy

Small parathyroid glands sit close to the thyroid and help control calcium levels.

They can sometimes become temporarily affected during thyroid surgery.

Low calcium may cause symptoms such as:

• Tingling around the mouth

• Tingling in the fingers

• Muscle cramps

Calcium levels may therefore be monitored after total thyroidectomy.

Temporary calcium supplementation is sometimes required.

Thyroid hormone after surgery

Patients undergoing total thyroidectomy require lifelong replacement thyroid hormone.

The medication replaces the hormone previously produced by the thyroid gland.

Patients who undergo lobectomy may or may not need replacement medication depending on the function of the remaining thyroid tissue.

Regular blood tests are used to adjust treatment.

Risks and considerations

Potential risks of thyroid surgery include:

• Bleeding

• Infection

• Neck swelling

• Temporary or permanent voice changes

• Injury to nerves controlling the vocal cords

• Low calcium levels

• Damage to the parathyroid glands

• Need for thyroid-hormone replacement

• Anaesthesia-related complications

• Need for additional treatment depending on pathology results

The individual risk depends on the reason for surgery, extent of thyroid removal and complexity of the case.

Thyroid surgery costs in Thailand

The cost of thyroid surgery in Thailand varies according to the amount of thyroid tissue being removed and the surgical technique.

A broad indicative range is approximately US$7,500–11,000 or more.

Factors affecting cost can include:

• Thyroid lobectomy or total thyroidectomy

• Conventional, endoscopic or transoral surgery

• Surgeon and anaesthesia fees

• Imaging and biopsy review

• Hospital stay

• Pathology testing

• Medication

• Treatment of lymph nodes where required

• Follow-up care

Patients with suspected or confirmed thyroid cancer may require additional investigations or treatment that are not included in a standard surgical quotation.
