Thyroid Surgery

Thyroid Surgery

Thyroidectomy

Thyroid cancer is an abnormal growth of the cells of the thyroid gland, a butterfly-shaped gland located in the front of your neck just below the voice box (larynx). Thyroid gland secretes hormones that help regulate the body’s metabolism and levels of calcium. Thyroid cancer is more common in women than men. People who are exposed to high levels of radiation to the neck and have a family history of thyroid cancer and goitre (enlargement of thyroid gland) are at a higher risk of developing thyroid cancer.

Generally, surgery involving thyroid gland removal is the most common treatment of thyroid cancer. Total thyroidectomy is a surgical procedure to remove all of the thyroid gland. Subtotal or partial thyroidectomy is a surgery to remove part of the thyroid gland. Your doctor may also remove the lymph nodes if the cancer has spread to the lymph nodes. The surgery is performed under general anaesthesia. The surgeon removes the thyroid gland by making a 3-inch to 4-inch incision in the middle of your neck, on top of the thyroid gland. A small tube (catheter) will be placed into the area to drain the accumulated blood and fluids.

Thyroid Biopsy

Ultrasound Guided Thyroid Fine Needle Aspiration

Fine needle aspiration is the most common method used for the diagnosis of a suspicious thyroid nodule. The procedure may also be referred to as needle biopsy which employs a hollow needle to remove small fragments of tissue for diagnosis. This procedure is performed under ultrasound guidance for accurate placement of the needle and identification of the suspicious tissue lesion.

Structure of the Equipment

The equipment consists of a thin needle with a small bore, to aspirate the cells, and an ultrasound imaging device for visualization of the thyroid nodule and to guide the entire procedure.

Procedure

The procedure is usually performed by a specially trained radiologist on an outpatient basis. The site for the insertion of the needle is cleansed with an antibacterial agent.  In some cases a local anesthetic may be administered around this region. A small amount of water soluble gel is applied on the skin over the thyroid gland and an ultrasound transducer is placed over it. The radiologist inserts the needle into the skin under the ultrasound guidance to identify the location of the nodule for the sample. After the collection of the sample, the needle is removed and pressure is applied over the site of insertion to stop the bleeding, if required a bandage may be used for dressing.

The Benefits

The benefits of the ultrasound guided FNA are as follows:

  • Accurate placement of the needle for sample collection
  • Less invasive
  • Less painful
  • Recovery time is short and patient can immediately resume their normal activities

The Risks

The risks of the ultrasound guided FNA include:

  • Bleeding at the site of insertion
  • Infection at the site of biopsy
  • Injury to the adjacent structures
