Did your doctor advise you that you need an operation to remove your thyroid gland? It is completely normal to feel a bit anxious or overwhelmed when hearing this. However, please know that this is a very common procedure performed successfully by many people worldwide, including here in Sri Lanka. There is absolutely no need to panic. At Nirogi Lanka, let’s talk about this thyroid surgery—or "Thyroidectomy"—in a simple way you can easily understand.
What is a Thyroidectomy?
Simply put, a "Thyroidectomy" is the surgical removal of all or part of your butterfly-shaped thyroid gland located in your neck. This gland is a vital part of your body that regulates metabolism and produces essential hormones.
There are two primary types of this surgery:
- Total Thyroidectomy: Your entire thyroid gland is removed.
- Partial Thyroidectomy/Hemithyroidectomy: Only one lobe (the right or left side) of the gland is removed.
The specific type of surgery you need depends on your clinical condition. Your doctor and surgeon will work together to decide the best path forward for you.
Why is a thyroid surgery necessary?
There are several reasons why a doctor might recommend this surgery. Let's look at the main ones.
| Reason for Surgery | In simple terms... |
|---|---|
| Thyroid Nodules | Lumps formed by cell growth in the thyroid. Some may be cancerous, while others might produce excess hormones. |
| Goiter | An enlarged thyroid gland. If it grows too large, it can press against your trachea (windpipe) or esophagus, causing difficulty in breathing or swallowing. |
| Hyperthyroidism | The thyroid gland produces more hormones than your body needs. Surgery is an option if this cannot be managed through medication. |
| Thyroid Cancer | If a biopsy confirms the presence of cancerous cells, surgery is performed to remove the affected tissue. |
Preparing for your surgery
Your doctor will clearly explain the steps you need to take before your operation. Typically, this includes:
- Testing: An ultrasound scan helps locate nodules precisely. If a lump is present, you may undergo a Fine Needle Aspiration (FNA) to rule out cancer.
- Voice Assessment: Your doctor may check your vocal cord function.
- Medication Management: If your thyroid hormone levels are high, medication may be prescribed to stabilize them. Be sure to tell your doctor if you are taking blood thinners or any other medications, as they will advise you on whether to continue or pause them.
- Fasting: You will be instructed to fast for several hours before surgery. You will receive specific guidelines on this timing.
What happens on the day of your operation?
Initially, an anesthesiologist will administer general anesthesia to ensure you are completely asleep and feel no pain. During the procedure, a breathing tube will be placed to assist you. Your surgeon may choose from several techniques:
- Traditional Approach: A small incision is made at the front of your neck.
- MIVAT (Minimally Invasive Video-Assisted Thyroidectomy): Surgery is performed through a very small incision using camera assistance.
- Scarless Approaches: Surgical access is made through hidden areas, such as inside the mouth or through the armpit.
If you are undergoing surgery for cancer, your surgeon will carefully examine the lymph nodes surrounding your thyroid and may remove them if there is any evidence that cancer cells have spread. Once the procedure is complete, the incision will be closed using dissolvable sutures, and a special medical-grade glue will be applied over the skin. Typically, a total thyroidectomy takes between 1 to 3 hours.
Are there any risks associated with this surgery?
A thyroidectomy is considered a very safe procedure. However, as with any major surgery, there are rare risks that you should be aware of:
- Bleeding: Excessive bleeding can potentially lead to breathing difficulties.
- Voice Changes: If your vocal cords are affected during the procedure, you may experience hoarseness.
- Damage to Parathyroid Glands: Located just behind the thyroid are four tiny glands known as the
(Parathyroid glands), which regulate your body's calcium levels. If these are disturbed during surgery, your blood calcium levels may drop.
Please remember that these complications are very rare. Your surgical team will take every possible precaution to prevent them.
What happens after the operation? (Recovery)
Once you wake up from anesthesia, you will be able to have light food and liquids. You will typically stay in the hospital for at least one night.
- Sore Throat: Due to the breathing tube used during surgery, your throat may feel sore for a day or two.
- Hormone Replacement: If your entire thyroid was removed, you will need to take a daily
(Levothyroxine)hormone tablet for the rest of your life. This is a simple routine that your doctor will discuss with you in detail. - Calcium Supplements: Sometimes, your doctor may prescribe calcium supplements for a few weeks to keep your blood levels stable.
- Healing and Scarring: Full recovery usually takes 2-3 weeks. It is best to avoid strenuous exercise or heavy lifting for a week or two. There will be a small scar on your neck, which will gradually fade over time.
When should you contact your doctor?
Once you are home, please contact your doctor immediately if you notice any of the following symptoms:
| Symptom | Urgent Action |
|---|---|
| Swelling, redness, pus discharge, or excessive bleeding at the incision site. | Seek medical advice immediately. |
| Fever higher than 101°F (38°C). | This may indicate an infection. |
| Numbness or tingling in your face, lips, or fingertips. | This could be a sign of low calcium. Inform your doctor promptly. |
| Significant difficulty breathing. | Do not delay; proceed immediately to the nearest hospital emergency department. |
