Understanding Thyroidectomy: What You Need to Know

Thyroidectomy, the surgical removal of all or part of the thyroid gland, is a common procedure used to treat a variety of thyroid conditions. Whether you’re dealing with thyroid nodules, hyperthyroidism, or thyroid cancer, a thyroidectomy might be the recommended course of action. As an ENT consultant, with a subspecialist focus on head and neck surgery, I have helped many patients navigate the complexities of thyroid surgery.

In this post, I will explain what thyroidectomy entails, when it’s necessary, and what you can expect during recovery.

What Is the Thyroid Gland?

The thyroid is a butterfly-shaped gland located in the middle of the neck, between the Adam’s apple and your collar bone. It produces a hormone called thyroxine that plays a crucial role in regulating metabolism, heart rate, and body temperature. When the thyroid isn’t functioning properly, it can lead to a variety of health issues.

When Is a Thyroidectomy Necessary?

A thyroidectomy may be recommended in several situations:

• Thyroid Nodules: If you have nodules on your thyroid that are suspicious for cancer, growing rapidly, or causing symptoms such as difficulty swallowing or breathing, surgery may be needed to remove them.
• Thyroid Cancer: The most common reason for a thyroidectomy is thyroid cancer. Removing the thyroid can help prevent the spread of cancer and improve treatment outcomes. Thyroid cancer has a very good prognosis.
• Hyperthyroidism: When the thyroid produces too much hormone, leading to symptoms like weight loss, rapid heartbeat, and anxiety, and other treatments (medication, radioactive iodine) are ineffective or not suitable, a thyroidectomy might be the best option.
• Goitre: A large, non-cancerous enlargement of the thyroid, known as a goitre, can cause symptoms such as difficulty breathing or swallowing, which may require surgical intervention.

Types of Thyroidectomy

There are different types of thyroidectomy depending on the extent of the surgery:

Total Thyroidectomy:

The entire thyroid gland is removed. This is often necessary in cases of thyroid cancer or severe hyperthyroidism.

Partial Thyroidectomy (Lobectomy):

Only a portion of the thyroid gland is removed. This may be done if the problem is confined to one lobe of the thyroid, such as a single nodule or a localized area of cancer.

Subtotal Thyroidectomy:

Most of the thyroid is removed, but a small part is left in place. This may be an option for some cases of goitre or hyperthyroidism.

The Thyroidectomy Procedure:

Thyroidectomy is usually performed under general anaesthesia and takes about 2 to 4 hours, depending on the complexity of the surgery.

During the procedure, I will make a horizontal incision at the base of your neck to access the thyroid gland. Careful attention is given to avoid damaging nearby structures, such as the parathyroid glands (which regulate calcium levels) and the recurrent laryngeal nerve (which controls your vocal cords). After the thyroid is removed, the incision is closed with sutures, and a small drain is placed to prevent fluid buildup.

What to Expect After Surgery

Recovery from thyroidectomy is generally straightforward, but it’s important to follow post-operative instructions carefully.

Pain and Discomfort:

mild pain and discomfort at the incision site are common but can be managed with pain medications.

Voice Changes:

Temporary hoarseness or a weak voice may occur due to the proximity of the surgery to the vocal cords. This typically improves within a few weeks. If this persists we can offer voice therapy or other procedures to help.

Hormone Replacement:

If you have had a total thyroidectomy, you will need to take thyroid hormone replacement medication (levothyroxine) for the rest of your life to maintain normal metabolism. I will work with you to determine the right dosage and refer you to your GP or an endocrinologist as necessary.

Calcium Levels:

If the parathyroid glands are affected during surgery, you may experience low calcium levels, which can cause symptoms like tingling or cramps. This can usually be managed with calcium supplements.

Follow-Up: Regular follow-up appointments are essential to monitor hormone levels, check for any signs of complications, and adjust medications as needed.

Potential Risks and Complications

While thyroidectomy is a safe procedure, as with any surgery, there are risks involved, including.

• Bleeding or Infection: these are rare but possible risks of any surgery. This is the reason I use a drain for your neck and you are given antibiotics during the procedure.
• Damage to the Parathyroid Glands: This can lead to low calcium levels, requiring long-term supplementation. It is more usual after a total thyroidectomy; hence you are likely to receive calcium supplementation initially.
• Vocal Cord Paralysis: some people may have a temporary change in the voice due to the recurrent laryngeal nerve being stretched during the operation. Very rarely permanent voice changes can occur. There are various options to help alleviate this.

Final Thoughts

A thyroidectomy can be a life-changing procedure, especially when it comes to treating thyroid cancer, severe hyperthyroidism, or large goiters. As your ENT consultant, I am committed to providing you with the highest level of care, from pre-surgical consultations to post-operative follow-ups, ensuring that you achieve the best possible outcome.
