You have recently visited your GP with a swelling or lump in your neck or with symptoms that could mean your thyroid is not working correctly. An operation is needed to remove part of the thyroid gland to be sent the laboratory for testing in order to get a diagnosis. This page gives you information about having surgery on your thyroid and the possible risks involved.

What is the thyroid gland?

The thyroid is a small gland in the front of the neck, just below the larynx (voice box). It is shaped a bit like a butterfly, being made up of 2 parts; the wings (lobes) with a central body (the isthmus). The function of the thyroid is to make hormones (thyroxine T4 and triiodothyronine T3) that keep the body working at its normal rate.

Diagnosis

As part of the process of getting a diagnosis, your consultant surgeon may need to remove part of the lobe. This is called a hemi-thyroidectomy (also known as a partial lobectomy). Cells that are removed from your thyroid gland will be sent to the laboratory where they will be looked at under a microscope to see if there are any cancerous cells.

About the operation

The operation will be performed under a general anaesthetic, so you will be asleep and unaware of the process. You will need to stay in hospital for 1 to 2 nights.

A small cut will be made at the front of your neck. The affected half of the thyroid gland will be removed and the cut will be closed. After the operation you will be given pain relief, such as paracetamol, which will help you feel more comfortable.

If you do not have any pain relief at home, please let your nurse know before you are discharged.

Following the operation, a scar will form. The scar is usually in a natural fold in the skin and will fade over a few months. As the wound begins to heal, gently massaging it with a simple moisturising cream will help the scar to flatten and fade.

Risks

As with any operation, there is a small risk of bleeding or infection which can be treated with antibiotics. Due to the position of the thyroid gland, the nerves that control the voice box may be damaged during surgery. If the nerve does become damaged your voice may sound weak and hoarse but this is usually temporary.

Follow up

Your doctor will see you in the outpatient’s clinic a few weeks after the operation. This will be when the results from the laboratory have been received.

The appointment details will be sent through the post after your discharge.

If a cancer diagnosis is confirmed, your doctor will explain what happens next and discuss further treatment with you.
